Essence of SinEdit

A alternative of Mom's Heart found in first floor of The End. It looks like mom's heart, except with all seven of the sin's fused together on it (They are all attached to greed, who is holding them up with a noose around his neck). You fight through the seven phases. Each phase with one of the sins disappearing.

Phase one, 7/7-6/7: Sloth fires 3 poison bombs at a time at Isaac. He then throws up in a circle leaving green creep except for the center. Repeat. Sloth then falls off with 25% health and you have to defeat him while the next phase starts.

Phase two 6/7 to 5/7: Lust is connected to pride with an umbilical cord. She drops down and spreads creep wherever she walks. She then pulls herself back up and throws syringes at you. Repeat. Lust drops with 25% health and you have to defeat her while the next phase starts. 

Phase 3 5/7 to 4/7: Pride shoots x lazers and + lazers alternating. An occasional troll bomb appears. He drops with 25% health and you fight him while next phase starts.

Phase 4 4/7 to 2/7: Gluttony shoot's a continuous lazer at you while firing a 8 projectile peep shot. Repeat. He drops and blahblahblah.

Phase 5. 2/7 Wrath just explodes. Joke phase.

Phase 6 2/7 to 1/7. Envy shoots little heads at you. Blahblahblah rinse and repeat

Phase 7 1/7 to 1/14 Greed drops greed heads around the arena. When the boss reaches 1/14 health, the starts grabbing the noose and makes choking sounds. His health starts dropping on his own, and he dies.

ZangiefB: Sorry I didn't mention this, but the End has only 1 floor.

Little IssacEdit

This boss only appears if the player has over 200 deaths in the game.

Found in first floor of The End

Appears in Hell (Or whatever floor is after Sheol, I'm sure someone has a fan idea)

Looks like dead isaac corpses strung together in a similar fasion to Little Horn from smb.

He is standing in a chasm that takes up the top half of the room, so you have to move in the bottom.

Little Isaac has 3 attacks. His first is he smashes his fist down on either the left or right part of the room. He then sweeps to the opposite side. Only the furthest row of tiles are safe from the attack.

His second attack is a slam attack. He slam's his arms down and lifts them. This attack spawns 4-6 of any humanoid enemy that looks similar to isaac.

His last attack is a head smash. He slams his head down covering all but two rows to the furthest from the center. This attack leaves fire tiles.

If you wanted to have an alternative boss to this one, you could make it little horn from smb. It's moveset has not been thunk yet.

Eye of Anubis Jr.Edit

A regular enemy spawned if Eye of Anubis is going to be the boss of that area. there is a 1-20% chance (chance increases when going deeper) to drop the polaroid as a pickup. a group of 10 Eye of Anubis Jr. appears as a miniboss in Sheol, Womb, Cathedral, and The Chest.

GodEdit

God is a boss located only in Heaven 2, and is the only boss there.

Phase 1: God will look like Isaac but with angel wings and gray hair, God will shoot white tears and white beams without warning. The music in this phase is "Carmeaty Burana" from super meat boy. only with more choirs.

Phase 2: God will shoot constant lightning bolts at Isaac. and also spawn 4-5 white troll bombs near Isaac. If Isaac doesn't beat him before the clouds turn grey, phase 3 begins.

Phase 3: God will grow gigantic,starting a mom type boss fight. but can still spawn troll bombs. when killed,there is a 30% chance that phase 4 will begin.

Phase 4 (optional): God will go back to his normal size. "Carmeaty Burana" will stop playing and "Escape!" from Super Meat Boy will play and a time limit will appear on the top of the screen. the time is 2 minutes. and God will spawn more lightning bolts and the background is a sky when going way down. If Isaac doesn't kill God in time, Isaac will die instantly. and the message will say that the player was killed by a crack instead of God.

SkinwalkerEdit

Skinwalker starts as a wolf in the middle of the room shoting red tears and chaseing Issac with max speed for 2 seconds when he reaches 50% health he will turn human and start shooting black brimstone tears in the cardnal directions and will turn into any boss except Mom, Isaac, ???, Mom's Heart, or Satan. when he dies he drops any devil or angel room item. the song playing will be 'Helpless' by Gothic Storm.

Kid DevilsonEdit

Actually, this is Vlad Cronqvist in boss form. It starts similar to the Isaac/??? battle, albeit, much weaker. Rather than using psychic tears or normal tears, he shoots Charm of the Vampire tears. He also occasionally summons Death, instead of several Angel Babies. The music will change once he reaches his second form, where he suddenly grows taller than Isaac, and changes his moveset, something similar to Castlevania Dracula.

Here, he will teleport, shoot triple tear shots at you or shoot a bomb and a delayed bomb, or even use "He is Coming" on you. Death still occasionally appears, to say hello, by cutting you open with his scythes.

Finally, after draining his healthbar once more, he changes into a form resembling Dracula's giant demon bat form the intro in Symphony of the Night. He jumps, similar to Monstro, and can either shoot Blood-Beams at one of the cardinal directions (which ever direction you are near him), shoot massive blood-tears, or make a massive leap and do a more localized version of He is Coming.

Theme 1: Crusade

Theme 2: Maybe a theme inspired by, but not exactly Dance of Illusions?

UboaEdit

Uboa is from the game Yume Nikki and is an alternate of Monstro II,he looks the same as from the game and when you start the fight you will see Poniko saying "Well, it was good to at least see you" then the battle begins

Form 1Edit

Uboa will fire Brimstone lasers from his eyes and shoot spiders at you, he will not jump on you but Uboa will move without an animation though.

Form 2Edit

Uboa will become a shadow and re-appear with his eyes bleeding and with his mouth gone, he wil now fire brimstone lasers at you more frequently and shoot homing blood tears at you till he dies.

Form 3,the final formEdit

Uboa says "You are strong, but I won't let you live!" and then the final battle starts, Uboa has Poniko's face and a hand in wich he holds a knife similar to the sacrificial dagger,he can:

-Summon's 1 invincible skeleton. (Poniko's skeleton)

-Teleports randomly and leaves a creep that has Uboa's face and slows and hurts you(making him really dificult)

-Summon's 2 troll bombs (both at him and you)

-Throwing the knife at you.

-Shooting blood tears.

When you kill him you hear him saying "I...wil..have.....my....revenge.....soon!" then he dies exploding. :D

Drops:

-Uboa's Soul (in production)

-Poniko's Memory (also in production)

-My Little Demon

Jack FrostEdit

Looks like Isaac, except is blue and has ice for hair. Found anywhere except Depths/Womb 2, Sheol, Cathedral. unlocked by using ???: The Cold 10 times(fan made Tarot card). By Anonymous

Attacks:

-Tries to hit you with blue tears that slow and do 1/2 a heart of damage

-Makes a Loki-esque pose, then shoots 8 ice tears

-On 50% health, charges you like Gemini while leaning blue creep that slows you down.

-On 5% Health, he will shoot blue Brimstone lasers at you, and will stop charging.

He drops the Soulless Winter passivated item(see Fan Made/Pickups)and 2 soul hearts. Also has a chance to drop The Polaroid for Wrath of the Lamb(10% chance).

The SlendermanEdit

The Slenderman is more or less Isaac´s fears all rolled into one. The music played is the Super Smash Bros Brawl remix of Snowman from Earthbound.

Phase 1Edit

Attacks:

  • Crush you with his long limbs.
  • Teleport from time to time.

Phase 2Edit

Slenderman grows HUGE and gets tons of tentacles around his head.
Attacks:

  • He will try to hit you with his tentacles causing 1 heart of damage. If he hits you, a mask will spawn that the duke of masks spawns and will try to kill you. the mask has more hp than usual.
  • He will shoot a brimmstone from one of his tentacles and will rotate where you walk to when it is firing the laser.

Phase 3Edit

Slenderman's tentacles stick to the ceiling

Will spawn Depths - womb bosses and when he spawns them he rises to the ceiling, unable to get hit. You must kill the boss to access hitting him.

Just like Mom's Heart, at one third of health left, it will stay down but instead of firing bombs, it will spawn bosses just like he usually does, but will stay down. He dies like Mom's Heart does, exploding and blood pours down from the walls. Then a tiny slenderman comes and starts beating you up. The hits do no damage. when you hit him once with anything, he dies instantly. He dies just like The Mask of Infamy's mask does, faces the screen and blows up.

DropsEdit

Slenderman will always drop the Slender figure.

The slender figure item allows Isaac to have a max speed stat but lower health. Also grants the power to smash rocks.

UnlockEdit

Defeating The Slenderman with ??? will unlock Zalgo.

No FaceEdit

It is a odd spirit, it seems to be strongly linked with Isaac's emotions.

It can replaces any boss from The Basement to The Depths but Mom. In its [1] Worm's Hole in Cavesbattle there will be Worm's Holes in corners of the room that summon Maggots every time and can't be stopped until No Face is completely defeated.


First ModeEdit


In this form No Face will slowly chase you and won't do anything besides this, however it has a great health and the Maggots can annoy you.

When its health reaches to zero it will change form and health will be filled again.


Second ModeEdit


[2]

Now No maicra will chase very aggressively like Lust.

In this form it can shoots black drops that slow you like those from Gish.

No Face besides chase you will try to eat the Maggots, if you can't manage to kill it before it eats enough Maggots it will change to the third and final form.

If No Face is killed in this form it will drop a normal boss item.

[3]No Face Second Mode BattleAdded by Colddyshadow


Third ModeEdit


[4]

No Face reaches its final form by the gluttony's corruption. It will walk in the room and charge in your directions like Chub. It can summons Baby, can also shoots black explosives projectiles that leave slowing puddles and a fast bloody tear that steals money like those from Greed.

When finally defeated it drops theFoolish Gold.


TriviaEdit



  • It is based on No Face from Studio Ghibli's movie Spirited Away.
  • While in First Mode No Face tries to be Isaac's friend, however it being constantly rejected and goes mad (Second Mode).
  • Third Mode is a reflex from Isaac's sins.

DestructionEdit

Destruction is a pitch black horseman with 3 eyes, huge brimston horns which go down it's head like hair except rougher and a crimson pony. Destruction can only be found in Limbo 1.

Phase 1: Destruction will roar and cause troll bombs to rain everywhere and occasionly drops 4 mega troll bombs under him. He will then dash towards you and repeat.

Phase 2: Once down to half health he will turn bigger and start shooting tears and blood beams at you (with the occasional mega troll bomb)

Phase 3: When he dies Destruction will fly up into the sky and leave you with a present. 6 MEGA TROLL BOMBS.

Destruction will drop the the mark which increases damage by II. It's more of a good luck than a parting present.

NOTE TO THE CREATOR: in the bible there are 5 horseman of the apoc,since binding of isaac is based upon christian religion, i dont think it will make it.

NOTE TO ^^^: Pestilence is not actually part of the Bible though, just a Horseman brought through popular culture.

CatalystEdit

Catalyst is a gigantic worm like scolex except pitch black and twice as long. He has 4 eyes and brimstone horns. At the end of his tail is a triachnid pinsir that's closed. Catalyst is only found in limbo 1.

Phase 1: Catalyst goes around like scolex except he's invincible. When he pops out of the ground he can pop out with his head or tail. If it's his head he'll fire 2 brimstone lasers at you. If it's his tail he'll be vunerable but he'll be stomping at you with a triachnid leg.

Phase 2:3 more doors will appear and Catalyst will initiate a mom-type boss fight. He will pop out either his head out of a door to shoot a laser or he will put out his tail to hit you with his vunerable triachnid leg.

Phase 3: Once killed he will explode into a tear rain that can hurt you.

Catalyst will drop the pact which gives you soul hearts and tears up. It's more of a good luck than a parting present.

Eye of AnubisEdit

[5] The Eye of Anubis is a rare boss found within the Catacombs. It is the manifestation of Isaac's fear of being judged by the eyes of others. It is unlocked by beating all the bosses in the Catacombs.
322px-IsaacVSEyeOfAnubis

Vs. Image


AttacksEdit

-The Eye of Anubis always starts off with a single blink, sending a salvo of 5 bullets towards the bottom of the screen.

-It can use its arm, made of tears of blood, to charge towards Isaac. If it slams into a wall, a dual Brimstone laser fires along the face of the wall.

-In addition, it may scrape its blood arm along the floor, causing a stream of arching blood (similar to Monstro's attack) to fly towards Isaac. Doing this makes it lose its arm, in which it will repeat its first attack until the arm comes back.

Champion FormsEdit

Pitch Black: Spawns with a clone, both smaller and faster. One will repeatedly charge at you while the other will focus on salvo shots. Neither will scrape their arms on the ground.

Green: Does not shoot a salvo of bullets. Instead, it hurls vomit bombs whenever it blinks. Scraping its arm on the ground creates multiple vomit bombs instead of arching blood. Charging leaves behind vomit creep but has no dual laser upon impact.

Purple: Larger, slower, and has about 25% more health. Shoots two homing shots instead of a salvo of bullets. Charging into a wall creates three purple-tinted brimstone lasers, the original two and a third going behind it.

DropsEdit

The Eye of Anubis has a chance of spawning an eye-based item upon defeat, including:


  • The Inner Eye
  • Mom's Contacts (If unlocked first)
  • Mom's Eye
  • The Peeper
  • Polyphemus

-The fourth time Whitehead lands, he spawns a purple creep that damages you on touch.

After being reduced to 25% health, all times he lands before every fourth time, Whitehead spawns four purple shots in all directions.

After killing him, Whitehead drops "Whitehead", which is a giant white pimple on your head that allows you to fire in all cardinal and ordinal directions, basically an upgrade of Loki's Horns. All the projectiles act the same, meaning if you have the Common Cold, all eight projectiles will poison enemies on hit. It can rarely be found anywhere else. If you have the item when you battle Whitehead, he drops Brimstone instead.

To unlock Whitehead, you would have to beat The Womb 30 times or make it through the Cathedral without getting hit once. When you unlock him, you'll get a message saying "Something pimple-like has appeared in the Utero"

HostileEdit

[12]Hostile 1st phase prototype ready. When I get Corel, it will be betterAdded by GarfieldMasterX

- by GarfieldMasterX

I saw that the Depths doesn't have many bosses, so I have an idea for a new Depths boss called Hostile. This boss is made of monsters.

400px-Hostile prototyp

Boss Image

- Mother Brains as feet.

- Maws as hands.

- Vis as body.

- Host as head.

Between Vis and other parts of the body will be some kind of balls like Mr. Maw ones after head attack. Hostile is huge somehow. Every part unless head can be attacked at any moment. In his first form he has that attacks:

- Punch with Maws.

- Make 3 steps with M. Brains while they spread bullets.

- Use body tentacles to make the Vis fire his lazer.

Host didn't attack in the first phase. When the one part is killed, the ties between them disappear. When Vis is killed all the ties are destroyed and the other parts start fighting like they usually do. ( Host still can't be attacked until the death of his partners). When they finally be destroyed the health bar is down to a half and the second phase begins. Host start growing to a Monstro size and has that attacks:

- Open up and fire lazers like The Fallen.

- Open up and fire bullets in a spiral type.

- Fire big lazer in the player direction.

- Spawn 2 Hosts.

He could be encountered in Depths normally like others, unless you have a Book of Sin . (Now the chances are 100%) He drops a spacebar item Hostile Skull which decreases each enemy attack to half a heart. I'm also thinking of Hostile II, but I need to know did you guys like my idea.

SkullerEdit

[13]Picture. Crappy work with Paint and Flash, but you guys got the ideaAdded by LucasKabiiby LucasK

The Skuller would be an depths boss and a rare necropolis boss wich sometimes would replace Mask of Infamy. The Skuller is a giant Host with some gray touchs and a angry face, his skull also has some cracks and he has stone hands with blood falling. Him would be unlocked by defeating all bosses that Necropolis and Depths have. (Not including Gish)

264px-Skuller

Boss Image

- Skuller uses one of hands to try to smash the player, causing half heart of damage if hit and splitting blood in a "+" direction

- Skuller tries to smash the player with all two hands, causing one heart of damage if hits the player, and splitting blood in a direction similar to Peep when he does a small jump (X and + directions)

- Every time that the player aligns directily in north to Skuller, his head opens up and fire a laser similar to Gluttony's

286px-Skullerunlock

Acheivement Unlocked

- If the player try to align in west, east or south, he will open up and fire blood, a salvo with 5 bullets. But after firing 2 times, he stops for a while

[14]Secret Unlocked! "Necropolis" is Written, but Depths could fit aswellAdded by LucasKabiiTo Beat him:- The primary way of damaging Skuller is attacking his hands when they come down to smash you, Skuller's head can't be damaged in the First phase

- You can also attack him when he's opening his skull to fire blood of a lazer, if so, the tears will do 1.5x more damage to him.

Phase 2

After losing about 60% of health, Skuller's skull will break, making him look like the red hosts, but still with a angry face, his hands will break too

- Skuller now can be damaged on his head anytime, but he will fire various types of bullet salvos including:

- 2 salvos with 4 normal bullets

- 1 salvo with 6 big bullets

- He still can shot his laser

- He now will summom 2 red hosts to help him (each on the sides) or one normal host (in front of him)

After Killing him, he will drop the "Lil Hosty" that attacks enemys firing 4 blood bullets. This item can be found on the item room, but it would be pretty rare. If you defeat Skuller already having the Lil Hosty, Skuller's drop will be a normal boss item.

CaasiEdit

By LucasK

[15]It would be like this...but more "Isaac-ish"
Cassi

Boss Image

290px-Caasi

Vs. Screen


Caasi (isaaC) would appear as a boss in any floor except for every level after the Womb. (He could appear as a mini boss in Sheol and Cathedral aswell) Caasi is a Entity that has the exact shape and size as Isaac,but inverted colours. Caasi would be unlocked after beating Isaac as Blue Baby.

Attacks:



- Mimic the Player Movements for 10-20 seconds, walk cicle and tears. The time would depend on the current floor you're battling him.

- The Tears that he would mimic would be rightly directed to the player instead of an o [16]Secret Unlocked!Added by LucasKabiipposite direction

- Spawning 2 doples in the Room

- Kick a troll bomb at the player

Caasi would also has a defense system that would make it harder to be hurt by bombs. If you put a bomb in the room, Caasi would place a super troll bomb aswell. So it would be more dangerous trying to damage him using a bomb next to him. Player's Tear's Rate and Strenght would be copied by Caasi, like. If the Player has more than 4 points of attack, Copier attack's would take one whole heart, if less, half a heart. But Caasi's range it's already "maxed".

[17]How about this?Added byZangiefB

[18]This is how caasI looks like right?Added by FlashMasterXD

Caasi's health would be choosed depending on the current floor, like. He would have a lot more health in the Depths than in The Basement. Upon killind Caasi, he would drop the item "Duplicator", that would create a clone of the Player to Mirror his movement and Attacks, the clone would last until the end of the current room, and the item would recharge at every 3 rooms.

PramkusEdit

By LucasK

278px-Pramkus2

Boss Image

Pramkus would be a boss that has random chance of appearing in the Angel Room. It would be Krampus's counterpart. He would act as a "guardian" or something like that. Pramkus has the appearance of a White Krampus, with a closed mouth and without the two "backhorns" that Krampus has. He has a halo with sticks around his two horns. Pramkus would fight like this:

- He starts firing much like Krampus does, 3 salvos of (white) bullets, one with 4, other with 5.

- He tries to charge at the player (but not chase) in a high speed, you can predict this when he does a roar. But it's hard to avoid when you has, like, Maggie's base speed.

- Like Krampus, he shoots (blue) lasers, but he can only shoot in two of the cardinal directions when you align with him in one of these

- Last but not least, he can make light beams fall off the sky, much like Isaac's final form

Pramkus would have the exact same health as Krampus. Upon defeat, he would drop The Pebble of Ice (see fan item ideas). Pramkus could drop some pickups aswell:





[19]Added by LucasKabii

- One Spirit Heart

- One full heart

- 3 super troll bombs

- A mostly good pill

- Ultra Rarely, a Eternal Heart

Upon rerolling the Pebble of Ice, it would result in a normal angel room item.

The ShadowEdit

By LucasK

The Shadow would be a boss that spawns in the Depths. Shadow would have the appearance of a human wich looks like Isaac is a bit bigger, his body is pitch-black and his eyes are red, but they are closed in the beggining of the Fight

- Shadow can't be attacked directly, when the battle starts, he has the form of a black Shadow in the floor wich moves constantly, if you touch it, you get hurt.

- The Shadow sometimes shoot out black bombs that explode in the Ground, making another Shadow that does not move, if the player touches it, he will get hit too, the created Shadow disappears after 5 seconds.

- After shooting out a bomb, Shadow will rise up the floor as the pitch-black person. He would shoot out 4 or 5 bullets that increase in size as far they travel. Now you can hurt him with tears.

- When he open up his red eyes, a lot of small hostile shadows will spawn in the floor.

- After a while, he will hide again in his Shadow form, then open up after doing the bomb attack.

Larry Stone is a boss: Spawns in the caves: 2 basic attacks:

LuciferEdit

By Qw3rtypounc3s

Lucifer is the final final boss of the game and is unlocked by defeating ???. After beating ??? a staircase that goes down into the ground will appear. Lucifers level goes in a straight line and is called DOOM. The line of levels will ONLY have bosses/minibosses, no enemys. Once you enter lucifers chamber there will be 2 satan statues and lucifers statue in the center. He will tell you that only Isaac is worthy to beat him and that you must prove you are Isaac. The only way to do this is to (A use the D6 in his chamber or (B Weild the polaroid. Upon doing one of these two, he will grin and spawn 2 krampuses from the statues. Once they are killed he will turn into his giant form and start viciously attacking you. Here are his phase 1 attacks:

Fire blood beams in front left and right.

smash both fists on the ground

spawn a mini fallen

fire 6 bullets

fly off the screen and stomp twice

After that form is killed he will summon black beams(like the holy beams, only unholy) and fly into the air and start STOMPIN'!

Phase 2 attacks:

Stompin'

Firing a black holy beam(unholy beam)

spawn any of the super sins

(Plus he is SUPER fast. If you don't have at least 4 speed ups your stuffed)

Also a bit more oomph in the form of phase 3!!!

Lucifer will turn into a more sized down (a little taller than you) version of himself, and will:

chase you around firing random shots, from freeezing shots to IPECAC shots.

If you are frozen/ slowed down, he will take the time to heal

He will also randomly fire a + blood beam then a x blood beam, then both at the same time

Once that form is killed he will make a LOUD roar of defeat Then fly off screen, at which point a chest will appear.

The cutscene will have Isaac opening the chest and having a holy light burst out of it, and he will smile, have wings and halo, and will fly up to the sky, presumably into heaven. Finito. Pics coming soon! (Lucifer sounds like lucifer from Dante's inferno, only slightly deeper) Could someone please add a picture? If i'm happy with it it stays.

The PuppeteerEdit

The Puppeteer is a Boss that sometimes appears in the Cellar.

[22]Added by Kasimiez
268px-The Puppeteer

Vs. Screen

In the first phase of battle you have to destroy the Isaac puppets. The puppets run around aimlessly but if you get to close they suddenly chase after you.

In the second phase of battle the Puppeteer will chase you fast while spinning his head around.The only way to hurt him is shooting him directly in his mouth. After his Mask is broken he will move slowely, while red Orbs spinn around him (they deal a half Heart damage), just shoot him till he is dead. He will drop the Best Friend.

The LambEdit

* Written before The Binding of Isaac: Rebirth *

By: ZangiefB

A powerful boss, can only be fought at the fanmade floor "The End". Here are his forms:

Form 1Edit

A crying skull with twisted horns lays on a pedstal. Enemies from lower floors slowly but continuously spawn. To make it stop, you have to attack the skull. There is no music at this point.

Form 2Edit

After Form 1's health bar is empty, the skull starts glowing white. A few seconds later, the skull floats in the air, and grows a skeletal body. The Lamb will then start chasing the player, shooting blood beams, firing salvo of 5 homing projectiles, and spawning more enemies (and eventually one of the seven deadly sins). During both this and the next phase, fast metal/electronic music with choirs plays.

Form 3Edit

The Lamb grows the purple skeletal wings Isaac grows from the trailer. He will then start rapidly spawning enemies, summoning heavenly beams in random places around the room, and shooting white projectiles in all directions.

After defeat, the music stops, light rays come out of his body, and The Lamb yells "ISAAAAC!!!" in a low-pitched voice similar to Satan. Then the screen goes white, and the player is taken into a completely white room with the chest in it. The white room has no name in the corner, and the music as heard in the library plays.

Zombie fetus

[30]Added by ShirakoYuri==Him==

"Him" is a new boss that appears in Omega. (see Fan Ideas/Floors and Rooms)

"Him" is actually the true form of Isaac, looking similar to Isaac holding items:The Nail, Lord of the Pit, The Mark. The Mark appears to be black white, though. (His body is dark grey, whereas the Mark would be pitch black)

Battle with Him

Phase 1Edit

The battle starts with Him sitting in the middle of the room, with messages appearing in the top of the screen (much like the ones that show up from Fortune Telling Machine. Trying to attack Him will result in nothing.

"You've finally come, my friend."

"You had a long way to go."

"You defeated my minions."

"But it will not be easy anymore!"

And then the actual battle starts.

In the phase 1, He shoots out three salvos of homing bullets - 4,6 and 8, respectively. He also sometimes teleports out of the room and spawns a random Boss. (possibilities include 2 Monstros 2, a pair of Hollows, The Bloat or two Teratomas. He teleports back once the summoned boss/es is/are defeated.

He also occasionally shoots out a blood beam in + pattern.

Phase 2Edit

When brought down to 75% of HP, will start charging at the player at notably high speed, but taking twice as much damage while doing so. He shoots out blood beams in a + pattern at the end of the charge, accompanied with spawning 4 Kamikaze Leeches.

Phase 3Edit

When at half of the HP, Him will start shooting violet bombs (in the amount of 3), which home at player. He also teleports around the room randomly. He occassionally shoots out 5-bullet salvos instead. (those do NOT home at the player, though)

Phase 4Edit

When His HP drops to the 25%, a message saying "Time to end this!" appears on the top of the screen.

Beams of light (similar to those created by Crack in the Sky) will start to cast, and Him will now shoot at double the maximum rate of fire - the shots are homing and explode, which effectively creates a lot of explosions.

Once player defeats Him, a faint cry will be heard and a message "I'll see you on the other side..." will appear.

Defeating Him with certain characters will unlock an item (open to suggestions).

Request An image of Him for VS screen.

Effectively the demonic Dople, albeit with black Mark (similar to that of Loki).

THE SERPENTEdit

The very serpent that started the long road of sin...And Isaac challenges him! The serpent will be found if you choose to fight him after killing ???, by either choosing the chest or a door that has the letters S Y N on the arch, including the heads of the super sins on the sides of the frame. The serpent is like pin cross scolex with satans head. Once you enter his boss room, he will yell "IIISSSSSAAAC!" In a high pitched sssssnake voice. He shoots 6 homing bullets, then 5 blood bullets. He will also randomly spawn any of the sins, super sins, or ultra pride. He will also summon unholy beams, and copy pins attacks, as well as scolexs. Upon killing him , you will be hit by an unmissable unholy beam, Then madgalene will come out of you and fly up into the sky. From then on she is unplayable. If you defeat the serpent again, cain will do the same, and so on and so forth, until the seventh time you defeat him, then he will rise from the ground, roar, and start chasing you. from then on you have to simply run aaway from him, seeing as he will chase you to the starting room of the chest. Then a rope will be tossed down from the sky, and you will climb it to meet-Maggy! she will then distract the serpent, and will possibly be killed whilst trying, but the distraction will give you time to run through the cathedral with the serpent shooting six blood bullets at you. You will keep going until you climb the rope up to the basement, and then, when the serpent comes up, he will stay in the same place hes in and start attacking you. He does the same attacks as his first form, only this time more quicker. Once you kill him a cutscene will play:

Isaac realises that he has no choice but to do gods bidding, and so he takes moms knife from the kitchen, With the serpent gaining on him, wipe a tear away, and plunge it into his chest, which makes the serpent roar in defeat, and die. Then Isaac is raised into the sky, and calls a voice(presumably god) Isaac, you have done my bidding, so I shall reward you: You shall be known as, SAINT, ISAAC! and Isaac opens his eyes.

A rare boss that can be found in the Catacombs, he very well resembles a Vomit Gaper, but larger. He has a primary feature of leaving green creep where he goes, much like Pestilence, but walks much faster and targets the player. His first attack consists of vomitting 4-5 green bomb-like blobs, like Sloth, that will scatter across the room and leave green creep when they land. His second attack is vomitting right where he is, causing the creep thathe is currently in to grow larger. After he only has 25% of his [32]Added by SkirdusHP left, he will pick up his head and throw it at the player, causing it to explode (leavingcreep) and lobbing 5 green bomb-like blobs across the room. He will now appear with no head and no longer be able to do his second attack, but he will speed up and begin using his first attack more often. He is a good chance at dropping Bob's Curse on death. (His name is a play on Putrid).

Can appear in Sheol as ordinary enemies. Do not appear in Cathedral. By Mnemonical.

Iblis (Wrath)

Takes on the appearance of Super Wrath, albeit darker with red eyes, burn marks on the "helmet" and curved horns. Spawns Mega Troll Bombs much like Super Wrath, however also scatters red bullets whenever shot. Furthermore, getting close to him increases the rate at which he spawns Troll Bombs.

Mammon (Greed)

Takes on the appearance of Greed, except with a dollar hanging from his neck, curved tusks from the mouth and bloody pennies in the eye sockets.

Furthermore, when tiny Leviathan blobs are killed, they will spray bullets in 6 directions.

Belphegor (Sloth)

Takes on the appearance of Super Sloth, except he is greener and lighter in color, but also has curved horns and mulligan-like infections across his body. Fires two poison bombs that spread in random directions, and spawns Brains. Furthermore, attacking him will cause red flies to spawn periodically. When killed, he'll go into an "ooze" state much like Globins, from which he will regenerate from with 10% of his HP if not killed.

ScleritisEdit

A giant eye, similar to the ones found in Sheol. Jumps around the room in a similar fashion to Widow, and occasionally fires a beam at the player. Can also spawn a single Eye (like the ones found in the Womb/Utero), and is allowed up to 2 on the screen at a time. Upon defeat, has a 90% chance of dropping Inner Eye, and a 10% chance of dropping Polyphemus. By Mnemonical.

SimonEdit

By Mnemonical.

First appear to be Isaac, albeit with a rosary cross around his neck. Has four forms.

1st Form - The PureEdit

Simon stands in the center of the room. Beams of light occasionally will appear around the room, hurting the player. Relatively easy to wittle down.

2nd Form - The DescentEdit

Simon floats into the air and his eyes glow white, like Isaac's would with Sacred Heart. He'll shoot out slow-moving white tears in 4 directions that have enhanced homing capabilities. Beams of light will continue to rain down from the sky.

3rd Form - The FallEdit

Simon's skin turns dark grey, and he grows demon wings. The blue cross around his neck becomes an up-turned red cross and his tears go from white to red. Same homing tears as before, except they will be red and travel a lot faster. Beams of light will no longer fall from the sky; instead, Simon will randomly spew out red bombs that leave harmful ooze behind.

K

Final Form - The DamnedEdit

Simon's final form. He grows curved horns like the Lamb, his expression turns evil, he grows demonic teeth and the mark appears on his head. Now, he will mirror Isaac's movements around the room, firing a salvo of red bullets in 8 directions at random intervals and firing salvos of 4 spreading bullets whenever Isaac shoots (albeit at a slower fire rate). Furthermore, if Isaac ever lines up horizontally with Simon, he will fire a laser without warning, much like the Bloat.

Upon defeat, a pentagram appears under Simon, and Satan's hand emerges, grabbing him and pulling the screaming Simon down into Sheol forever more. Simon is the final boss of my fan idea scenario, the New Genesis. It can be found in Fan Ideas/Floors and Rooms.

The SwarmEdit

By ZangiefB

The Swarm is a boss similar to the Duke of Flies, only much more powerful, found only in the Depths or Necropolis. He appears as a dead gaper being carried by a ridiculous amount of flies. If you've defeated the Duke of Flies or the Husk in the same run, the chance of finding him is higher.

Form 1Edit

The Swarm is carried around the room by the flies in a similar way to the Duke of Flies himself. The dead body being carried coughs up a random type of fly every now and then. The swarm of flies carrying it will get smaller every time you hit him, and red flies will come out of it automatically.

Form 2Edit

At three quarters of health, the swarm of flies will be completely gone. The gaper will start chasing the player at a moderate speed, occasionally stopping to cough up more flies or spit a black bomb that also spawns flies when it hits the ground.

Form 3Edit

At half health, the gaper's body explodes into a bloody mess. His head is kept off the ground by flies. He will then use the same movement and attack pattern as Form 2, only he attacks at a much faster rate.

Final FormEdit

At one quarter of health, the flies lifting the head will die, thus the head finally touches the ground. He will then start using the same movement pattern as a Hopper, but he leaves red creep wherever he lands. He uses the same attack pattern as before, only at a nearly unpredictable speed, and with an added attack: a stomp similar to a Membrain, but when he lands, a large puddle of the sme creep spawns under him.

After defeat, he will drop any fly-related item, excluding Skatole, along with health like usual bosses.

MirrorEdit

Mirror is a boss, which could only appear in Angel Rooms and the Cathedral. If you've defeated Krampus already, he couldn't appear in Angel Rooms anymore.

Phase 1Edit

His behavior in this phase is the same like a Dople, but if you could fly, he could to and he has the same shoots like you. His range is at minimum, so you have to attack him by range. If your range is at minimum too, you must damage yourself, but unlike you, Mirror isn't invincible after one. When you reduced his live to half, he activates an endless version of the Unicorn item, until he hits you once. Now the second phase starts.

Phase 2Edit

Mirror now has the same stats and items (including bombs, trinkets and "Space-items") as you. Now he walks independently through the room and attacks you. He wil activate the space-item when you reduced his live to a quarter (If he has the batterie, the candle or the habit, he will use the space-item as often as possible). If he has the Teleporter, he will use it to, but is instantly killed.

After he is defeated, two random Angel Room items will be dropped.

The 7 SinsEdit

The seven sins aren't a really new boss. All of the seven sins will appear in the same boss room. In the Womb, the Utero, the Sheol, the Cathedral and the chest, it would be at least four super sins instead. Ultra Pride could never appear as part of this boss.

The ArchangelsEdit

The Archangels are equated to the Harbingers, but have a different behavior. They are looking like little white versions of Satan, but without any face, which also could be compared with the angel in the Angel room. All of them make damage by touching and shooting spectral tears on the player. If you kill all in one run, you unlock Abbadon.

MichaelEdit

Michael is one of the Archangels, who appears in the Basement and Cellar. He has big wings, which makes it impossible to attack him from behind or site, so he could only attacked from the front. He tries to hide behind stones to attack you with his spectral tears. If you've killed him, he drops the Archangel Wings (Fan idea item).

GabrielEdit

Gabriel is also an Archangel, who appears in the Caves and Catacombs. He has normal wings, like all Archangels out of Michael, but instead of tears he uses the Sacramental Bread item (Fan idea item) to attack you. His attacks have the spectral upgrade to. Unlike Michael, he tries to come close to you, to give you also the touchdamage. If you've beaten him, he drops the Sacramental Bread.

RaphaelEdit

Raphael is the third Archangel. He appears in the Dephts and Necropolis. He has small wings and normal tears, but if he hits you, he regenerates live. He also tries to hide behind stones and attack you with his spectral shoots. After he is defeated, he drops the Soul Eater (Fan idea item).

UrielEdit

Uriel is the last Archangel. He appears in the Womb and Utero. He has small wings and maximum speed. He attacks you only but often with the God's Eye item (Fan idea item). He only stops while he is using it, so now you can attack him without he is dodging. If he is killed, he drops the God's Eye.

AbbadonEdit

Abbadon has wings and spectral shoots like an Angel, but he isn't an Archangel. He has two phases with differently behavior. After he is unlocked, he could appear in Sheol and Cathedral in a random room.

Phase 1Edit

Abbadon has all Archangel items and looks like one of them, but he changes Sacramental Bread, God's Eye and Spectral tears as attack. He isn't as fast as Uriel but faster than the other Archangels. He tries to hide behind stones like Michael and Raphael. If you reduces his life to 50%, he loses his wings and falls to the ground. A cloud appears around him. Now the second phase starts.

Phase 2Edit

The cloud disappears, so now you can see the demon form of Abbadon. He is completely black and has Brimstone, Vampire Charm (which is activated with a 100% chance), the Anarchist's Cookbook (which he can use as often as he wants) and the Spirit of the Night. He is resistent to bombs. He changes now Brimstone, the Anarchist's cookbook and spectral tears as attack against you. For every 10% he loses from his live, he spawns a random sin (no super/ultra sins). After he is defeated, he drops a random Angel room and a random devil room item.

TwinsEdit

By ZangiefB
Twins

This picture took a LOT of effort.

Like The Fallen, this boss has a rare chance of appearing anywhere except for in areas where final bosses appear, although much rarer than The Fallen himself. The lower the floor, the higher chance it has of appearing, and the more health it has. For example, this boss would be really hard to find in the Basement and would have the health of Monstro, but would be fairly common in the Womb and have the health of Blastocyst.

This boss has its own music, part angelic, part satanic.

AttacksEdit

Demonic Twin
Twin demonic

The demonic twin.

  • Shoots blood projectiles similar to the pattern of Monstro's giant hop attack.
  • Shoots a salvo of 3 blood projectiles toward the player.
  • Summons a Demon Baby (See Monsters) or Kamikaze Leech.
  • Uses Krampus's Brimstone laser attack, however, this can sometimes be an X instead of a +, or if low on health, he will do it in all cardinal and diagonal directions simuntaneously.
  • Teleports around the room.
  • Chases the player at a fairly high speed for 10 seconds. If he manages to touch the player, he stops and the player recieves 1 heart of damage.

<u>Angelic Twinthumb|link=

  • Shoots homing projectiles in the same manner as Isaac.
  • Calls down 1-3 beams of light.
  • Shoots a white IPECAC style bomb at the player.
  • Summons an Angel Baby or Holy Leech.
  • Teleports around the room.
  • Dashes toward the player at a notably high speed just like Chub would, with his wings glowing white. If he manages to touch the player, he stops and the player recieves 1 heart of damage. Unlike Chub, he cannot be paralyzed by bombs. Doing this will stop him in his path, but sends the bomb flying at nearly light speed in the direction he was charging.

Unlike all other bosses, it drops two items: one satanic item where the demonic twin dies, and one Christian item where the angelic twin dies.

The angelic twin can spawn as a mini-boss in the Cathedral, and the same for the demonic twin in Sheol. Rarely, this can be the other way around.

The HATREDEdit

Boss of the floor TIME

When you enter the room, there will be a ghost like figure standing there (completely black except for glowing red eyes, upper body looks like isaac except for fact lower body is a ghost like tail coming out. He will stand there in that pisition staring at you. No matter where you move, he will stare at you. The battle begins when you first lay a hit on him.

Phase 1Edit

Movement: The hatred will move around the room to random spots. No other real movements.

Attacks: He will stare at the player and fire a DEADLY accurate red shot that may take out 1 heart and a half depending on players stats. If player has the wafer, damage reduced to 1 half. Rarely he will head towards you and turn red signally that he will shoot a beam like monstro 2 towards whichever direction you are in. If you are diagnol, He will instantly fire five shots like the ones above.

Health: About 10 hearts. Each shot should take out 1, but hes pritty darn hard to hit because he moves fast.

Strategy: A good idea is just to dodge him untill he charges at you and then hit him while he prepares his LAZOR or when hes going diganol, You could get 5 hits off of that.

'Phase 2'.1Edit

Shape: The ghost will begin to shake where you defeated him and phase one and parts will begin to crumble off.

Movement: He will try anything to get away from you in this phase. Charge at him and get revenge for whatever he did to you in the first phase >:3

Attacks: Very rarely will he spawn a charger. Nothing to worry about, just hit it.

Health: About 5. Each hit will take off 1 heart, so this shouldn't take too long.

Condition: If you take too long to kill him off in this form (which i doubt any legit isaac player would) he will release a giant black light that overwhelms the screen and insta kills. It takes a VERY long time for this to happen.

Strategy: No fears, charge at him and lure him into the center area to get the most damage out of him.

Phase 2.2Edit

Shape: After tasting defeat, the crumbles will become colossal and the screen will go dark. After it goes back on, he will be about 3 times his original size (original was about as big as isaac) And he will appear as a demonic spirit with skeletal dark glowing red wings behind him. His eyes glow red and so does his body. Oh, your in for a treat now.

Movement: He will go side to side from the edges of the top wall at the start. After awhile, he will turn and go up and down on the left or right wall. After done on the left or right wall, he goes to top one and pattern repeats.

Attacks: While he is on the top one, he will fire a beam downwards occasionally similar to satans second form. He also will shoot out a large amount of red bullets like the ones from phase one in a formation similar to monstros attack. Sometimes when your infront of him or beside him he will shake then charge strait at you. This is easy to dodge if you see it coming, deadly if you don't. It will probably take out 2 hearts. Wafer reduces it to 1. Also, when he returns to his spot he will be temporily stunned. (very very short time) When he is on the side walls, he will do the same pattern as this just in the direction he is tilted.

Health: 40. Your shots will only take HALF hearts off him, remember that.

Strategy: Deadly huh? I would focus on dodging and hit him when he uses the beam or when he recovers from using the charge attack. Save health here, because the last phase is terryfying.

Phase 3Edit

After he is hurt he falls onto the ground and turns grey. When you head towards him clocks will appear and start ticking superfast and overwhelm the screen. After they disapear you will be in the room, however its abit darker than it was before and the Hatred is gone. Then a voice like satan laughs Hahaha! and then he will appear, slightly bigger then in the last form. Exact same appearance, through. However, he appears to be preparing for something.

Movement: He will stay at the TOP of the room, SIDES of the room, or BOTTOM of the room and commonly switch those spots.

Attacks: He will move his hands outward and grin then on the wall grey clocks will appear and fire out beams similar to monstro 2. These do 1 heart and 1 half, regardless of wafer or not. You can squeeze inbetween 2 shots however. His hands will glow red and he will releases a giant stream of bullets that weaves in then goes out then stops. They spread over time and would do 1 heart of damage on touch. He is vunerable while doing this. He grins and his mouth opens releasing a grenade towards you. After that he will look puzzled and release 2 more. After that he is vunerable for a split second. Grenades would do 1 heart and 1 half.

Health: 50. Again, half hearts. That means he takes 100 hits.

Strategy: Well, this is terryfying. Your most of the time too busy dodging to hit him. 3 Key places to hit him are- 1: If you can get infront of him while the clock move is going, you take no damage and DEAL damage.

2: After he releases grenades. Dodge the 2 ones he releases quick, and hit him for a split second. 5-10 shots should go in there.

3: Get in close when hes about to release the bullet streams. You can get in good hits AND dodge the bullet streams in the same attack.

Also, to dodge the bullet stream, after time the bullets will have holes, and the bullets spreading will make those so big that you can fit through them. Repeat and Defeat.

Final PhaseEdit

Shape: After defeating him the room will light up again. 2 chests that contain enough hearts to heal you and have a chance of giving you 1 heart will appear. After they are opened the large chest at the end will appear. However.. When you open it a godly looking form of Hatred with a mask to cover up wounds on his face will emerge. Ooooh, time for the final final battle.

Movement: He moves for diffrent attacks. Check attacks for info.

Attacks: His attack cycle works like this = 1st: Moving to the top of the room, he will scream spawning 2 hoppers and 2 chargers, who have a chance of being champion buffed, and he will shoot out 3 monstro 2 type lasers infront of him. If you are infront of him, you just lost 2 hearts. Ouch. 2nd: After you dodge that beam he will glow and a spirit will rotate around him like a angel baby or cube of meat. The spirit can be destroyed by hitting it 40 times (20 health- only take off half hearts) and while that is there, he will spawn more hoppers and chargers for any that you kill. He will continue to do this untill the spirit is destroyed. 3rd: He will teleport all over the room charging something. If you hit him in the short time before he teleports to a diffrent spots he will be shocked and go onto his next phase. If you don't do it fast enough, gigantic hands will come out of where ever he finished the attack and charge right at you dealing 1 heart and 1 half for each. 3 Hearts down, also they are UNAVOIDABLE. Final: After that the mask egnites with a purple flame and he will begin shooting purple bullets that take 1 heart out rapidly at you. At one point he will stop and throw 1 purple grenade at you and almost immediatly after that another one. Grenades take 2 hearts. After the grenades he does another purple bullets as long as he did the first one then he goes to the center of the room where he glows vunerable. After being hurt the attack cycle goes back to 1 and it repeats.

Health - 4. He is invincible to all damage except for the part after his attack cycle. Have fun with that. Also, you can only score 1 damage. Meaning the attack cycle is done 4 times. Ouch.

Strategy: DODGE DODGE DODGE. Heres the attack cycle for you:

1st: Don't mind the hoppers or chargers here, just try to not let them lure you close to him. You WILL be punished if you don't do what I just said.

2nd: Take out the minions, because there is a slight delay for the respawning. Hit the spirit once there is a oppertunity. The chances are it should die in 2 - 4 oppertunitys to hit it.

3rd: Pay attention to only one direction. If you keep firing in one direction, that wont work because the bullets will be blocked and he will teleport out. When he comes in, thats your que to hit him.

Final: Run run run, Wait till the bullets get close the run to a diffrent section of the room. Repeat untill he begins throwing grenades. Grenade dodging is easy to figure out. After that repeat the top section then hit him. Repeat all of this advice untill he is dead.

Death: He goes out in a bang, Where the darkness of him fades away and he screems ISAAAAAAAAAAAAAAC as he dies. After most of his body is gone, it explodes and the entire room is silent. A chest appears infront of isaac. What is this chest? Go check out the floor TIME in fansuggustions/floors. Also after beating, a note will appear saying LOST TIMES have appeared in the basement.

AbominationEdit

By ZangiefB
Abomination

Picture by ZangiefB

Abomination is a boss that can be encountered in Necropolis or The Depths, or rarely in The Caves or Catacombs replacing Gurdy.

He is named after the Abomination from World of Warcraft, an undead, ogre-like creature made of corpses cobbled together.

Just like Gurdy, he is static, sitting in the middle of the room.

AttacksEdit

  • Lashes out one of its arms at the player.
  • Spits a red explosive projectile at the player that explodes into normal red projectiles like Monstro's super hop attack.
  • Makes a fart sound and oozes out dark brown creep that both slows and damages the player if he touches it.
  • Vomits a salvo of 7 green projectiles at the player.
  • Attempts to grab the player with one of its many arms. If he manages to grab him, he will pull him towards his body and try to eat him, dealing 1/2 heart of damage every 5 seconds. The player can break free by either attacking him or placing a bomb.

​When defeated, he will explode violently and drop a common boss item.

Mega LumpEdit

By ZangiefB

The Mega Lump, as its name suggests, is a greatly enlarged Lump. It is a <u>boss that appears in The Womb and Utero.

AttacksEdit

  • Spits a wave of red projectiles in the same manner as Monstro.
  • Shoots a Brimstone-style blood beam from its mouth.
  • Goes into the ground for 3 seconds and pops back up close to the player.
  • Spawns 1-3 smaller Lumps by hacking them up.

The Duke of MasksEdit

A superior version of the boss Mask of Infamy.

It is unlocked after defeating The Mask of Infamy twice.

It can be be encountered in The Depths and the Cathedral.

Phase 1 Edit

Dukeofmasks1


It will slowly chase after Isaac, shooting blood drops (similar to Monstro's) that will cause half a heart of damage of damage. In addition, it will also summon little masks (see below). The Duke's heart follows close behind and acts as its weak spot.

Little Mask

LittleMask

These masks will bounce around the room diagonally. Touching them will cause half a heart damage to Isaac. It takes 3 tears for not upgraded Isaac to kill one.

Phase 2:Edit

DukeofMasks2

When Duke of Masks loses its heart, it eyes will begin to glow with rage and its face will form an angry mouth with teeth showing. Its speed increases by 250% and it will begin to shoot a brimstone-like beam either from the front, the back or even from both sides. Like in phase 1, little masks are stoll summoned. The back of the mask will continue to stay its weak spot.

Phase 3Edit

DukeofMasks3

When the Duke is nearly destoryed, its crown will grow twice its size and seize control of the mask.

It will start chasing relentlessly (without the need to take a break unlike similar bosses like Gemini)

The Duke of Masks will (similar to the Headless Horsemen) drop one of two special items:

  • The Duke's Crown
DukesCrown


Drops 5-7 Coins and 2-4 Keys
  • Mask Minon
MaskedMinionLittleMask Isaac


Increases Damage, Speed and Health by 1

Bobby

Boss Image (by Greygoo64)

Le bobby

My version of bobby

BobbyEdit

Ever wonder what happened to Brother Bobby, since we assumably know what happened to Magdalene/Maggy? 

Bobby appears to be a larger (Roughly a bit smaller than Gurdy), Gaper of the happy variant, wearing a crown similar to that of Pageant Boy, but larger and purple instead of pink. He is a two phased boss battle. 

He is a boss that appears on the Basement/Cellar 1, Basement 2, and very rarely Caves (Not Catacombs) 1 and 2.  He may also show up in the Chest, but not alone. In the chest, he is usually accompanied by another Bobby, or a Gurdy Jr, or a Duke of Flies, or a Husk, or a gemini, or maybe paired with two lusts.

(If someone could provide a picture, please do. That would help! ^_^)

Phase 1Edit

Bobby follows you like the average Gaper would, but he is quite slower than you at base speed and should never capture you. To add a slight bit of difficulty to a rather easy encounter, he spawns Gapers of the happy variety and of the frowning variety. These Gapers are the same as normal ones and have a chance to become a Pacer or Gusher when killed. He may also spawn Horfs and the various other zombie-like mobs encountered only in the basement. He will spawn them in groups and won't spawn another set of mobs until you kill the existing spawns. You can kill Bobby without having to deal with the mobs he spawns until the very end after he dies so you can progress. He has a chance to spawn champion mobs too. He only spawns mobs in groups of two and rarely three at this phase, and it should be very easy to kill.


Phase 2Edit

At half health, like most Gapers, his head explodes and he's basically a giant gusher. At this phase, he wanders around randomly, and shoots small bullets in groups the size of monstro hordes of bullets in the direction he's facing, though his movement is random as said basically meaning his tears are random. Most of the tears he shoots will deal half a heart of damage, easily noted by their average size, though like Monstro, very few can deal an entire heart, as noted by their larger size.

He also starts to randomly fire Ipecac missiles, and can easily be seen when he shakes up for roughly half a second before lodging out 1-3 Ipecac bullets. They land where the player was standing just before Bobby started shaking and should be easy to avoid. When firing Ipecac shots, he doesn't shoot monstro-like hordes of projectiles.

There is no set pattern to this and he alternates between ipecac and wide spreads of bullets randomly. He starts to spawn Globins, a step up to Cave monsters, though the difficulty is reduced from fighting Globins because Bobby can reduce them down to an ooze state in one ipecac and kill them with another. He tends to do both attacks quite frequently, so if you play strategically, you can let Bobby kill the Globins while dodging easily as you widdle away at him. 

Upon DeathEdit

Once he dies, he explodes into blood, which does nothing but cover the floor in blood just like the blood created from killing any other mob. Mobs that you haven't killed spawned by him still live and the room is uncompletable until you kill these mobs. He drops normal boss items and drops like any other, though has a 10% chance to drop Little Bobby. If you have Little Bobby before encountering this boss, Little Bobby disappears until the fight is over.

Champions of this bosses include a tankier variant with more health, and a variant that spawns flies and spiders and nubs instead of zombies, as well as a variant that spawns nothing that just runs as fast as a normal Gaper. There is also a variant that in second phase, he only shoots Ipecac.

Overall, this boss is Basement/Celler style difficulty and ranks among the harder ingame Cellar/Basement bosses in difficulty, though he isn't a stretch and is a believable first boss encounter.

Notes:Edit

If you have Brother Bobby OR Sister Maggy on the Basement/Cellar and you've recieved one before you faught the boss, you are destined to encounter Bobby as a boss in either Basement/Cellar 1 or 2.

If you have Brother Bobby, he has a 10% chance to drop a random familiar you do not have, and a 90% chance to drop a random average boss item.

He CANNOT drop orbit familiars or 3rd/4th level meat boy, or Dead Bird.

He is based off of Brother Bobby, an item that is based off of Isaac's dead PRESUMABLE brother as there is Sister Maggy, who is obviously an item relating to Isaac's dead sister, Magdeline who he cross dresses as. 

It is possible that Bobby was like Isaac and fled to the basement, died, and ruled the zombies in the basement.

Although he's not an entirely difficult and masochistic boss, both phases have the same health as the average monstro, meaning in total, he has double the health of monstro. This boss isn't terribly difficult or punishing, and his difficulty mainly comes from his second phase where he produces alot of bullets and you're bound to take a hit or two, maybe three or four in that phase and need to dodge often. This boss follows along the line that you PROBABLY won't die, he won't nearly kill you, but he will atleast get one or two hits on you, maybe five if you're unlucky. The average time to kill this boss isn't long or tedious. Just double the average time it takes to kill monstro without a good damage item, which is common to be nearly bare that early in the game. He's pretty much that boss that's like a road bump. Not much of a problem but can slow you down. As a boss that massively spawns, rage is a preferably item thus making Samson more of a good character in the early game with the bosses that spawn mobs who are in abundance.

He's the type of boss that hurts you and slows you down, but makes up for it considering that most of the time, bosses drop hearts/soul hearts/eternal hearts, as well as guaranteed upgrades.
