| 23 | ->Debut: ''The Binding of Isaac'' |
| 24 | ->Debut (Super variants and Ultra Pride): ''Wrath of the Lamb'' |
| 25 | |
| 26 | \ |
| 27 | The physical embodiment of the Seven Deadly Sins, which can be encountered as mini-bosses on any floor barring the Chest and Dark Room. Stronger variants known as the Seven Super Deadly Sins can sometimes replace the normal sins. |
| 28 | ---- |
| 29 | * AmbiguouslyHuman: It's not clear if they are humans under the effect of various items[[note]]The Virus makes Isaac resemble Lust without the pink coloration and Mr. Mega gives him Wrath's "mask"[[/note]], humanoid monsters from the start, or the actual Sins themselves given physical embodiment. The implication that [[spoiler:every character is an alternate Isaac as he only imagined the events of the gameplay]] just complicates things further. |
| 30 | * AnthropomorphicPersonification: They're humanoid personifications of their respective sins. |
| 31 | * DegradedBoss: Zig-zagged. The sins, along with their Super variants, can be encountered as mini-boss enemies following the Womb, but it's still possible to encounter them as a mini-boss in a floor. |
| 32 | * KingMook: The "Super" variants introduced in ''Wrath of the Lamb'', as well as Ultra Greed in ''Afterbirth''. |
| 33 | * InescapableAmbush: Unless you hold certain items, they won't show up on the map at all until you run into them, and you cannot leave unless you carry a teleportation item. Their rooms also have metal bars around the doors so that you cannot even bomb your way out as you could with normal enemy rooms. |
| 34 | * QuirkyMinibossSquad: They fight you individually, but in any of the levels following the fourth chapter, you may encounter up to three different Sins to fight in the same room. |

| 38 | !!Envy/Super Envy |
| 39 | [[quoteright:142:https://static.tvtropes.org/pmwiki/pub/images/envy_new.png]] |
| 40 | A grinning sin that bounces around his room diagonally, splitting into two heads when killed initially and continuing to split when killed. '''Super Envy''' will split into three heads when killed initially, and each subsequent head moves at a faster pace. |
| 41 | ---- |
| 42 | * AsteroidsMonster: When defeated, he splits into two heads, which each split into two smaller heads, which finally each split into two tiny heads. Super Envy splits into threes instead of twos, except for the smallest heads. |
| 43 | * DamageSpongeBoss: To make up for the fact that he is easily the least dangerous Sin in either form, he has more aggregate health than the other Sins. |
| 44 | * KaizoTrap: The last Super Envy head killed can drop a Troll Bomb. |
| 45 | * SlasherSmile: The usually amusing trollface turns into a more terrifying one when it belongs to something vibrating and hovering ominously towards you. |
| 46 | * ShoutOut: Envy's main expression resembles a [[Webcomic/RageComics trollface]], while the smallest variant resembles a pokerface. |
| 47 | * VillainousBreakdown: While most sizes of Envy's heads are smiling, the second-smallest is actually grimacing angrily. The smallest size just doesn't know what to think anymore. |

| 52 | [[quoteright:210:https://static.tvtropes.org/pmwiki/pub/images/gluttony_new.png]] |
| 53 | A fat sin that fires a Brimstone laser at Isaac if he gets in his line of sight or shoots an 8-way projectile shot otherwise. '''Super Gluttony''' fires a laser from both ends. |
| 54 | ---- |
| 55 | * BloodFromTheMouth: A non-lethal example with Super Gluttony, who has blood emitting from his mouth. |
| 56 | * DoesThisRemindYouOfAnything: If you stand above Gluttony (and, to a lesser extent, Super Gluttony) when they shoot upwards, it looks disturbingly like they're flashing you. Which, like Vis, they kinda are. [[BloodyMurder To the viewer's utter chagrin.]] |
| 57 | * FatBastard: Both of them try to kill you and, par for the course for Gluttony personifications, they're also overweight. |
| 58 | * HighPressureBlood: He shoots Brimstone lasers from his belly, like a Vis. Super Gluttony fires out his back, too, like a Double Vis. |
| 59 | * KingMook: He's basically a Vis with a head, with Super Gluttony being a Double Vis with a head. |
| 60 | * VisualPun: A very disturbing one. His chest has been slashed open right where his heart would be, there is blood around his mouth (mainly as Super Gluttony), and (as Gluttony) he frequently drops <3 on defeat. The implication? ''He literally ate his heart out.'' |
| 61 | [[/folder]] |

| 63 | [[folder:Greed/Super Greed]] |
| 64 | !!Greed/Super Greed |
| 65 | [[quoteright:204:https://static.tvtropes.org/pmwiki/pub/images/greed_new.png]] |
| 66 | The shopkeeper now risen to life, who can appear in either a shop or secret room. He creates Hoppers and shoots 3 projectiles that cause Isaac to lose coins if hit. '''Super Greed''' will appear after Greed has been killed in a previous floor and now spawns Keeper Heads and shoots 4 projectiles. |
| 67 | ---- |
| 68 | * BanditMook: His shots (and [[CollisionDamage mere contact]] with him) take away a couple of pennies from you, while making you drop a variable amount on the floor that you can try to retrieve. Just be careful while doing so, if you don't want to be [[DeathByMaterialism killed in the process]]. His mook-look-alikes have the same ability as him. |
| 69 | * BreakoutCharacter: He's the most memorable and ubiquitous of The Seven Deadly Sins mini-bosses, and ''Wrath of the Lamb'' cemented his status by adding a quite a few new versions of him. [[spoiler:And ''Afterbirth'' makes Ultra Greed the final boss of Greed Mode.]] |
| 70 | * CharacterBlog: The ''Afterbirth'' AlternateRealityGame [[https://twitter.com/iamisaacsbody gave him a Twitter]]. On the other hand, most of the entries were made by the ''players'', who completed the ARG by logging into the account and posting tweets. |
| 71 | * ChestMonster: Replaces shops and secret rooms. He's more likely to appear as you go further in the game. |
| 72 | * DegradedBoss: While several sins appear as enemies in the Womb onward, Super Greed can be encountered as a mini-boss enemy as early as The Depths. |
| 73 | * {{Expy}}: He shares some traits with ''VideoGame/{{Spelunky}}''[='=]s Shopkeeper, including his multi-shot ability, potential to turn hostile on the player without previous warning, and overall [[{{Jerkass}} dickishness]]. |
| 74 | * KingMook: ''Wrath of the Lamb'' added Super Greed, who is bigger, meaner, scarier, and can spawn Keepers, who are essentially Greed heads. They can also appear in the Depths, the Catacombs, and the Necropolis. [[spoiler:Also, the final boss of ''Afterbirth''[='=]s Greed Mode is Ultra Greed.]] |
| 75 | * MirrorBoss: Fighting him as Keeper invokes this trope. |
| 76 | * MookMaker: Normal Greed summons Hoppers, while Super Greed summons Keepers (which are Greed heads). |
| 77 | * MoneyForNothing: {{Invoked|Trope}}; he gives a lot of money when defeated, but his battle has a tendency to replace a shop where there would ''be'' one. There's also a chance he might appear in Secret Rooms, making for a bit of a subversion. |
| 78 | * MookPromotion: {{Inverted|Trope}}. The game's standard version features him as a mini-boss, but the expansion added mook-versions of him that share some of his most aggravating attributes.[[note]]Multi-shot and, most importantly, the ability to drain your money.[[/note]] |
| 79 | * NooseNecktie: A prominent fixture of his design. |
| 80 | * PreFinalBoss: A pack of Greeds or Super Greed are possibilities for the last fight [[spoiler:before Ultra Greed in Greed Mode]]. |
| 81 | * UpgradedBoss: Unlike other Super Sins, which can replace a normal sin regardless if their normal variant has been encountered, Super Greed can only appear as a mini-boss once normal Greed has been killed. |
| 82 | * TookALevelInBadass: He's pretty unimpressive as a mini-boss even in his super form, then comes [[spoiler:his Ultra Greed form]]. |
| 83 | * WingdingEyes: Super Greed either has cent signs for eyes or actual coins jammed in his eye holes. |
| 84 | [[/folder]] |
| 85 | |
| 86 | [[folder:Lust/Super Lust]] |
| 87 | !!Lust/Super Lust |
| 88 | [[quoteright:204:https://static.tvtropes.org/pmwiki/pub/images/lust_new.png]] |
| 89 | A sickly-looking sin that chases after Isaac, dealing contact damage. '''Super Lust''' will leave a trail of red creep wherever she runs. |
| 90 | ---- |
| 91 | * AbhorrentAdmirer: Possibly due to being the personification of Lust and not exactly in the [[FacialHorror good-looking department]], and her only attack is chasing after the player at great speed and causing CollisionDamage. |
| 92 | * BadassNormal: Pride can spawn bombs from nowhere and has SuperScream or can stretch out tentacles. Greed can sap money away from Isaac through collision or even ''bullet contact'' and can spawn monsters. Lust, however, just seems to be a fast girl with a harmful virus. Super Lust averts this by having a trail of harmful blood that doesn't damage her, which is not "normal" by any standard. |
| 93 | * BloodFromTheMouth: Super Lust seems to have blood leaking from her mouth, though not as much as Super Gluttony. |
| 94 | * BloodyHorror: Lust seems to be affected with some sort of blood disease (likely HIV) and her Super variation bleeds from the face and leaves a trail of blood everywhere she goes. |
| 95 | * BullfightBoss: She does nothing but charge at you. Thankfully, she can't turn on a dime and there are plenty of rocks around to kill her momentum. |
| 96 | * DoesThisRemindYouOfAnything: Lust and Super Lust's diseased appearance bear reference to sexually transmitted diseases, and Super Lust's battered and bleeding face implies a rough or violent sexual act. |
| 97 | * FacialHorror: Both of them have deformed faces, ''especially'' Super Lust. |
| 98 | * FragileSpeedster: Not really that tough of a battle compared to the other Deadly Sins since her only gimmick is just running really fast, and she can be brought down rather quickly even with no special tear upgrades. What would make her dangerous, though, is if you had a very poor speed stat. |
| 99 | * PinkMeansFeminine: Both Lust and her super form are pink, and she's the only Sin who is female. |
| 100 | * TheSmurfettePrinciple: The only one of the Sins/Super Sins that have been identified as female. |
| 101 | [[/folder]] |

| 104 | !!Pride/Super Pride |
| 105 | [[quoteright:204:https://static.tvtropes.org/pmwiki/pub/images/pride_new.png]] |
| 106 | A sin that attacks by either shouting or spawning four Troll Bombs. '''Super Pride''' will fire projectiles when he shouts and spawn two Mega Troll Bombs. |
| 107 | ---- |
| 108 | * CallingYourAttacks: Pride's expression indicates which attack he's going to do; a forever alone face means he's going to do his shout attack, while a trollface means he's going to spawn bombs. |
| 109 | * MadBomber: Occasionally, Pride randomly spawns Troll Bombs in an attempt to catch you in the blast. |
| 110 | * PaletteSwap: In ''Wrath of the Lamb'', Super Pride's appearance was just that of Pride, but larger and pink instead of grey. In ''Rebirth'', the face is slightly different, but he still resembles a giant, pink Pride. |
| 111 | * ShoutOut: Makes a [[Webcomic/RageComics trollface or a forever alone face]] before attacking. |
| 112 | * SuperScream: One of his attacks consists of him screaming. The attack is represented by zigzagging lines forming an X-shaped cross around him. His super variant will fire six projectiles while shouting. |
| 113 | [[/folder]] |
| 114 | |
| 115 | [[folder:Sloth/Super Sloth]] |
| 116 | !!Sloth/Super Sloth |
| 117 | [[quoteright:204:https://static.tvtropes.org/pmwiki/pub/images/sloth_new.png]] |
| 118 | A palette-swapped globin sin that spawns Chargers and vomits an Ipecac projectile towards Isaac. '''Super Sloth''', also palette-swapped, will vomit two Ipecac projectiles. |
| 119 | ---- |
| 120 | * GreenAndMean: His skin is sickly green since he's ''quite literally'' rotten. |
| 121 | * GreenAroundTheGills: He's permanently green and he vomits out Ipecac shots for one of his attacks. |
| 122 | * LastNameBasis: Sloth is his last name, according to WordOfGod. His first name is [[AerithAndBob Bob]], as in the one referenced by items related to poison bombs like Bob's Rotten Head. |
| 123 | * MadBomber: He'll belch out green spit bombs. |
| 124 | * MookMaker: He'll spawn Chargers on occasion, while his Super variant will spit out two spiders. |
| 125 | * PaletteSwap: Of the Globin. See below. |
| 126 | * StealthPun: Unlike the other sins, Sloth is a PaletteSwap of an existing enemy, in this case the Globin. ''Sloth has a lazy character design.'' |
| 127 | [[/folder]] |
| 128 | |
| 129 | [[folder:Wrath/Super Wrath]] |
| 130 | !!Wrath/Super Wrath |
| 131 | [[quoteright:204:https://static.tvtropes.org/pmwiki/pub/images/wrath_new.png]] |
| 132 | A sin wearing a bomb suit that randomly wanders and throws bombs at Isaac if he spots him. '''Super Wrath''', instead of throwing bombs, will spawn a Mega Troll Bomb wherever he stands. |
| 133 | ---- |
| 134 | * AlienBlood: While the normal Wrath averts this via having red blood, Super Wrath instead bleeds grey. |
| 135 | * AshFace: Super Wrath's face is sooty and blasted, implying at a bomb-handling attempt that went awry. |
| 136 | * CartoonBomb: His bombs are identical to yours, skull marking and all. |
| 137 | * {{Expy}}: Of VideoGame/{{Bomberman}}, as they both look like him (though it's more prominent with Wrath) and fight using bombs. Both of their rooms also often have hard blocks making them into a grid shape, like in classic ''Bomberman'' games. |
| 138 | * MadBomber: Throws bomb after bomb at you. Since he's Wrath, this doubles as a StealthPun. |
| 139 | * TacticalSuicideBoss: Probably the finest example in the game, as he has exactly one attack which can easily [[{{Pun}} blow up in his face]]. This can result in [[HilarityEnsues hilarious situations]] where, if you have the Bobby-Bomb collectible, every bomb the boss drops proceeds to walk back toward him. Less so with Super Wrath, as he throws Mega Troll Bombs, which follow the player around and cannot be pushed. However, these can potentially be lured into him. |
| 140 | * WrongGenreSavvy: He seems to think he's in a ''Bomberman'' game. This doesn't work out too well for him, since Isaac can just push his bombs back at him with tears. |
| 141 | [[/folder]] |
| 142 | |
| 143 | [[folder:Ultra Pride]] |
| 144 | !!Ultra Pride |
| 145 | [[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/ultra_pride_new.png]] |
| 146 | Two familiar-looking sins comprised of a humanoid that spits out a huge trail of green creep and his baby familiar that teleports occasionally, which can randomly replace both Pride and Super Pride as a mini-boss. |
| 147 | ---- |
| 148 | * AlienBlood: Has green blood. |
| 149 | * CreatorCameo: He's a stylized representation of artist Edmund [=McMillen=], while his familiar is one for programmer Florian Himsl. [[MeaningfulName Hence why he's]] [[SelfDeprecation named Ultra Pride.]] |
| 150 | * DeathByCameo: You do fight them, after all. |
| 151 | * DualBoss: He comes with his familiar, and both have to be defeated. Sometimes, two Edmunds or two Florians can appear instead of one. |
| 152 | * MeaningfulName: The creators are ultra proud of their product. Additionally, putting yourself as a cameo in your own game is usually a show of pride, because why would you put yourself in your own game if you aren't proud of it? |
| 153 | * MythologyGag: As of ''Repentance'', if you defeat Edmund first, Florian has a small chance to drop an Eternal D6 if you've unlocked it, which is a reference to ''Eternal Edition'', which Florian made. |
| 154 | * PaletteSwap: He's basically Sloth with different moves, while the familiar is a graphically altered Baby with a different shot type. |
| 155 | * PowerAtAPrice: Both of the items you can get from them: |
| 156 | ** The Left Hand is a Trinket that replaces every chest that spawns with a red one. While you can score some pretty good items out of them without the need for keys, you can also just spawn Spiders or Troll Bombs. |
| 157 | ** The Eternal D6, being gained if you beat Edmund first, acts exactly like the extremely powerful D6 with a faster recharge time… but has a 30% chance of straight-up deleting the item you tried to reroll. |
| 158 | * ZombiePukeAttack: Instead of spawning Chargers, he has an attack where he pukes out green creep. |

| 166 | ->Debut: ''Christmas Update'' |
| 167 | |
| 168 | \ |
| 169 | A demon that can occasionally appear in a Devil Room as a mini-boss. It possesses similar attacks to The Fallen. |
| 170 | ---- |
| 171 | * BadSanta: Most often drops a Lump of Coal, which [[CursedWithAwesome increases the damage of your tears based on how far they travel]] and gives Isaac an AshFace. |
| 172 | -->'''Item Description:''' My [=XMas=] present. |
| 173 | * ChestMonster: Randomly appears in Devil Rooms. He's more likely to appear if you have already entered a Devil room, even more so if you've made a deal. |
| 174 | * EarlyBirdCameo: He can be fought in Greed mode, even if he hasn't been unlocked yet. |
| 175 | * HighPressureBlood: Just like the Fallen, but he'll do it if you pass by him in any direction rather than after a charge. ''Afterbirth'' adds in a chance of him rotating his beams, and ''Afterbirth†'' adds in a chance of him firing them off ''diagonally''. |
| 176 | * TheKrampus: It's in the name, after all. |
| 177 | * MiniBoss: By virtue of being a weaker version of the Fallen, not to mention he has the same kind of entrance as the Seven Deadly Sins. Though unlike the Sins, he only appears in Devil Rooms and is the only mini-boss that [[AllYourPowersCombined Delirium]] can turn into. |
| 178 | * MovesetClone: He was initially one of The Fallen, except he doesn't split into two and lacks the chase portion, just taking the cardinal lasers and projectile spray. DLC for ''Rebirth'' diversified his attacks, adding occasional rotating lasers in ''Afterbirth'' and the ability to fire diagonally in ''Afterbirth†''. |
| 179 | * {{Nerf}}: His rotating laser was given a tell in ''Afterbirth†'', where he'll do a short lunge towards the center of the room first (this also prevents undodgeable lasers when he starts the attack against a wall). It also nerfed the Head of Krampus item though, removing the occasional rotating lasers it would do. |

| 185 | ->Debut: ''Rebirth'' |
| 186 | |
| 187 | \ |
| 188 | Secret bosses in ''Rebirth'', a fight with one of two Angels is initiated by bombing the statue in an angel room at any point throughout the game. Beating one unlocks a piece of a key each time, and beating both and combining the keys allows the player to unlock the true final boss of the game. |
| 189 | ---- |
| 190 | * TheBlank: Even when not in statue form, they lack faces. |
| 191 | * BoltOfDivineRetribution: They shoot coherent beams of holy light, which functionally behave like Brimstone lasers. |
| 192 | * ColorCodedForYourConvenience: Uriel wears silver or blue, Gabriel wears red. |
| 193 | * DegradedBoss: Two Fallen Angels attack you as [[spoiler:Mega Satan's flunkies]], and to get to that point, you're almost required to have already killed the normal ones in this run. [[spoiler:One interpretation of this is that they kept the pieces of the Golden Key safe, failed when Isaac took the pieces, and were subsequently punished for it.]] Incidentally, the degraded versions are actually ''stronger'' than the originals. |
| 194 | * DismantledMacGuffin: They each hold a piece of the key required to open the Gold Gate. |
| 195 | * DualBoss: ''Afterbirth†'' gave Angel Rooms a chance to contain two angel statues, letting you fight both at once if you are so inclined (or are short on bombs, or used Mama Mega on the same floor). However, before ''Repentance'' fixed it, fighting both at once will only spawn one Key Piece, making it better to fight them in sequence. |
| 196 | * EarlyBirdBoss: Though Gabriel is the stronger of the two, they spawn in random order, making it possible to fight him rather than Uriel on an early floor. |
| 197 | * GuideDangIt: [[spoiler:Bomb the angel statue in an Angel Room to provoke it into a fight. Less aggravating than other examples since there are more in-game clues and it is often next to blue fires, which can be bombed for soul hearts, so the player might figure this out by mistake if nothing else.]] |
| 198 | * HiddenInPlainSight: [[spoiler:Those statues in the Angel Room aren't just there for decoration. A fight can be initiated at any point in the game, provided you have beaten either ??? or The Lamb and a spare bomb.]] |
| 199 | * OurAngelsAreDifferent: They are much larger than Isaac and have [[TheBlank no faces]]. They're also [[LightIsNotGood hostile and attack Isaac]] like every other boss in the game (though Isaac has to pick a fight with them, rather than the other way around). |
| 200 | * PaletteSwap: Their main distinction is the color of their scarves. Uriel wears a pale blue one, while Gabriel's is red. [[spoiler:Delirium makes note of this when he mimics either of them.]] |
| 201 | * PersonalSpaceInvader: Unlike Uriel, Gabriel likes to fly directly at Isaac to deal contact damage. |
| 202 | * WingedHumanoid: They have wings and are human-like, although they're also [[TheBlank faceless]]. |

| 208 | ->Debut: ''Repentance'' |
| 209 | |
| 210 | \ |
| 211 | After grabbing Knife Piece 2 in a subarea of the second floor of the Mines or Ashpit, an invincible ghostly being of Mom's face will chase after the player until they leave the subarea. |
| 212 | ---- |
| 213 | * AdvancingBossOfDoom: There's literally no way to fight her once she appears. All you can do is run away and hope to escape back into the Mines/Ashpit with your life. |
| 214 | * CollapsingLair: Zig-zagged. When Mother's Shadow awakens and begins the chase, the whole area starts to shake with rubble falling down, indicating it will collapse and kill you if you don't get out in time. However, barring Mother's Shadow draining your health with CollisionDamage, there's no risk of taking your time getting to the end. |
| 215 | * DungeonBypass: The main difficulty of the encounter involves having to bomb your way to escape, due to rocks being in your way and single tile-wide gaps needing to be filled in with those rocks being blown up. However, characters with built-in flight (Azazel, The Lost, etc) can just fly straight to the exit without needing to bother with all of that. |
| 216 | * EldritchAbomination: Just what the hell is this thing? It's obviously related to Mom, but there's no foreshadowing of its existence apart from how Mom looks on the box art of ''Repentance''. It borders on GiantSpaceFleaFromNowhere. |
| 217 | * EvilSoundsDeep: Mom's voice is pitched down to the point it sounds far more ethereal and nightmarish. |
| 218 | * ImplacableWoman: The Mother's Shadow is invincible and will continue to chase after Isaac until he reaches the end of Knife Piece 2's area. And by "invincible", [[NoSell we mean she's immune to everything that could possibly hurt her.]] Not even the fabled [[OneHitKill Chaos Card]] works on her! |
| 219 | * MovesetClone: It isn't apparent at first, but her attacks mirror that of [[spoiler:Dark Esau]], only without the OneHitKill CollisionDamage. She even has a similar if not identical {{Hitbox|Dissonance}}, despite being a lot larger. |
| 220 | * NightmareFace: Whatever Mom originally looked like in reality has been twisted and warped into a terrifying visage, where only her mouth and eyes are discerned from the dark shadowy body. Her mouth is filled to the brim with ScaryTeeth, and her eyes are [[RedEyesTakeWarning a crimson red]]. |
| 221 | * NoGearLevel: Her area takes away all non-"story" items the player has obtained up to that point, forcing them to avoid her with base stats and no items to help. Flying characters can still just fly to the end. |
| 222 | * NothingIsScarier: The Classic variation. Before her encounter, the player needs to go through a series of empty and quiet rooms first, with no monsters on sight. Then after getting the Knife Piece at the very end, she appears and chases the player down. |
| 223 | * RedAndBlackAndEvilAllOver: She is entirely red and black and one of the most threatening obstacles in the game. When she appears, all the torches light red, and the empty pits are filled with a strange red glow. |
| 224 | * UnstoppableRage: Mom is apparently so incensed by Isaac putting the Knife Pieces together that she manifests as this dark monstrosity in an effort to kill him on the spot. |

| 240 | * ClippedWingAngel: The Grey Champion version is bigger with more health and uses his bullet spray attack more frequently, but he can't use the leap attack of the normal version, making it far easier to circle around and shoot with no risk to yourself. Even in pairs, he's much less of a threat. |
| 241 | * DegradedBoss: After the game is beaten six times, he'll start showing up as a boss enemy in The Depths onwards. |
| 242 | * DualBoss: The Red Champion version is two smaller Monstros with less health but the same attack pattern. |
| 243 | ** Double Trouble boss rooms can contain Monstro paired with another Monstro, The Duke of Flies, Larry Jr, or Fistula. |
| 244 | * FlunkyBoss: Monstro can occasionally appear with several enemies, such as Flies, Gapers, Hoppers, Mulligans, or Ministros. |
| 245 | * EasterEgg: One Active item, Monstro's Tooth, calls in the aforementioned boss to body-slam enemies. On the chance that you end up getting it as one of your first items, guess which boss you can't use it against. |
| 246 | * HeelFaceTurn: The Monstro's Tooth item lets you summon him to crush your enemies. Just make sure there's actually something for him to hit, or else… |
| 247 | * KingMook: To the Ministros added in ''Afterbirth+''. |
| 248 | * PreFinalBoss: Oddly enough, Monstro will occasionally appear before an [[spoiler:Ultra Greed]] battle. |
| 249 | * UnskilledButStrong: His Gray Champion version trades his high jump for being bigger, tougher, and having the ability to shoot his bullets faster. |
| 250 | * WarmUpBoss: One of the less complicated bosses and one of the most likely to run into first. Many prefer getting zero-damage boss battles on Monstro to increase the likelihood of Devil Deals spawning. |

| 259 | \ |
| 260 | A blood-soaked segmented worm that wander around its room, splitting into shorter individual variants if any of its segments are destroyed. |
| 261 | ---- |
| 262 | * AsteroidsMonster: Not so much as other bosses, but if the middle section is killed first in a 5-segment one, it will split into two more versions with just two segments. This happens much more easily with his Eternal counterpart in the ''Eternal Edition'', where a broken-off segment can last as just a head and can regenerate segments. |
| 263 | * TheCameo: A smaller version of [[VideoGame/MeatBoy Larrie's Lament]]. |
| 264 | * DegradedBoss: One of the earliest boss enemies to be encountered, appearing as early as The Caves. |
| 265 | * DualBoss: Easily the most common one; his standard fight in the Basement is always two of him. ''Afterbirth'' occasionally mixes things up with a single very long Larry Jr., but he'll likely be splitting into multiple Larries over the course of the fight anyway because of how the boss works. |
| 266 | ** Double Trouble boss rooms can contain a Larry Jr. paired with Monstro, Pin, or Sisters Vis. |
| 267 | * DungFu: Will randomly spawn poop while moving, which serves as an obstacle. |
| 268 | * FluffyTheTerrible: Larry Jr. is a blood-coated demonic giant maggot, yet has one of the most cutesy-sounding names in the game. |
| 269 | * KingMook: As of ''Wrath of the Lamb'', smaller enemies similar to it appear. |
| 270 | * SegmentedSerpent: Larry Jr. is composed of several body segments that have individual HP bars and can be destroyed separately. Killing a segment in the middle of its body can cause it to split into two individual worms, but a segment cannot survive if it isn't attached to another. |
| 271 | * UpgradedBoss: Blue Champion Larry Jr. has more health and is larger, but cannot spawn any poop. Green Champion Larry Jr. will occasionally fire a projectile in the direction that its facing. |
| 272 | * WarmUpBoss: Shares this with Monstro. He's a common early-game boss who can't even shoot at you (except for the Green Champion version), but his movement patterns can be erratic thanks to the poop he leaves behind. |

| 283 | ---- |
| 284 | * BodyHorror: It's safe to assume that the only reason he can move around is because of the flies that have infested his bloated body. He also lacks eyes of any kind. |
| 285 | * DegradedBoss: After unlocking "Everything's Terrible!", he can appear as a boss enemy in The Depths onwards. |
| 286 | * DualBoss: Double Trouble boss rooms can contain The Duke of Flies paired with another Duke of Flies, Monstro, or Rag Man. |
| 287 | * FatBastard: He's evil and fat-looking. |
| 288 | * FlunkyBoss: "Attacks" by creating tons of flies, which act as both defense and offense. |
| 289 | * MeaningfulName: His name is a reference to Beelzebub, a demon often referred to as the "Lord of Flies". |
| 290 | * MookMaker: As his name implies, he creates flies. |
| 291 | * KingMook: To the Dukies. |
| 292 | * TakingTheBullet: Spawned flies circle the Duke until he commands them to attack you, letting them soak up your shots. |

| 304 | ---- |
| 305 | * AllThereInTheManual: Their actual names aren't mentioned in-game at all. They come from ''Gish'', which they were originally designed as a boss for [[DummiedOut but never got implemented]]; the larger twin is Contusion while the smaller twin is Suture. |
| 306 | * BigGuyLittleGuy: Contusion is the big twin, Suture is the little one. |
| 307 | * BrainsAndBrawn: Suture is the Brains while Contusion is the Brawn. |
| 308 | * BullfightBoss: Contusion can tire out after a few moments of charging the player. If he is killed first, Suture will turn red, give chase, and never tire out. |
| 309 | * ConjoinedTwins: Suture is an underdeveloped parasitic twin. |
| 310 | * DegradedBoss: Begins appearing as a boss enemy in the Womb onwards. |

| 312 | ** Double Trouble boss rooms can contain Gemini paired with another Gemini or Rag Man. |
| 313 | * FetusTerrible: Both of them seem to represent fetuses, even having an umbilical cord attached to each other. Suture even moreso. |
| 314 | * GameBreakingBug: Not necessarily game-breaking, but fairly annoying. The game will not count Gemini kills if you kill Contusion first (which happens 99% of the time). To unlock the Cellar, you need to have killed every Basement boss at least once, which this bug makes very difficult. |
| 315 | * HeelFaceTurn: The Gemini zodiac sign item gives you a friendly copy of Suture who attacks your enemies. |
| 316 | * PolarOppositeTwins: Contusion is aggressive and chases you; Suture looks calm and makes ranged attacks until you kill his brother, at which point it charges at you. |
| 317 | * TurnsRed: What Suture does when Contusion dies, chasing after Isaac in a blind fury. |
| 318 | * UpgradedBoss: Blue Champion Gemini will have Suture firing homing shots, while Green Champion Gemini will have the twins already separated. |

| 332 | * ConjoinedTwins: Averted, despite the splash art. Little Steven is never actually attached to the main Steven, and instead just floats near him. However, the Steven item does give Isaac a conjoined twin on his head. |
| 333 | * DeliberatelyMonochrome: He's a pure black and white contrast, like his entire home game. He even overrides [[spoiler:Delirium]]'s colour scheme! |
| 334 | * DegradedBoss: Appears as a boss enemy only in Sheol. |
| 335 | * DualBoss: More or less the same fight as Gemini, except Little Steven will begin chasing the player while big Steven is still alive once his health gets low enough. |
| 336 | * HeelFaceTurn: The Little Steven item summons a friendly version of Steven who shoots at enemies, and is almost always dropped by this boss (except when it drops the "Steven" item instead, which is just a damage upgrade). |
| 337 | * LastDitchMove: Both parts of Steven shoot bullets in all directions when they die. |
| 338 | * TimeTravel: Described as "Something from the future" in his achievement, so it's very likely he did this. |

| 353 | * BadBoss: She has no issue stepping on her own minions. |
| 354 | * BodyHorror: She's made out of a head with four eyes, leg bones, and toes. |
| 355 | * ConfusionFu: The Black Champion version fires a six-bullet spread at random orientations. |
| 356 | * DarkIsEvil: The Black Champion version spawns big spiders with half health instead of sacks, and shoots 6 bullets instead of spiders. |
| 357 | * DegradedBoss: Begins appearing as a boss enemy in Necropolis onwards. |
| 358 | * FragileSpeedster: Relatively low HP for a boss, but moves fast and unpredictably and spits out the equally unpredictable spiders, making her harder to beat without taking any damage than most bosses early on. Her Pink Champion version emphasizes this a bit more: she jumps faster, but is smaller and weaker. |
| 359 | * GiantSpider: She's a larger version of the Trites, which are spider-like. Considering that those are already the size of Isaac, it can make for an intimidating boss fight! |
| 360 | * MookMaker: Not only does she spawn spiders directly, but she can also spawn Sacks. And that's not even getting into the ones that can spawn bigger AsteroidsMonster spiders or other kinds of Boils. |
| 361 | * KingMook: To the spider enemies, particularly the Trites. |
| 362 | * PinkMeansFeminine: One of her champion colors is pink, and she's one of the few female bosses. |

| 380 | * PerpetualFrowner: The only expression Pin has is a sad frown. It even looks like the ":C" {{Emoticon}}. |
| 381 | * SandWorm: A Sand ''Tapeworm'' at that, but nevertheless, it's a giant worm creature that attacks by burrowing through the earth and diving out of the ground. |
| 382 | * SegmentedSerpent: Like Larry Jr., Pin has multiple body segments that take damage separately. However, what separates Pin is that each segment does not have a separate health bar, which will cause it to take significantly more damage from piercing and explosive attacks. Amusingly, attacking Pin while it's petrified or throwing a Chaos Card at it will destroy its segments, shortening its body significantly. |
| 383 | * TacticalSuicideBoss: It is not immune to its exploding Ipecac projectiles, and due to a quirk in hit detection, can actually damage itself with them when it begins to bury underground. [[RemovedAchillesHeel The dark grey one averts it, replacing the bombs with bullets.]] |
| 384 | * WarmUpBoss: Competing with Larry Jr. and Monstro for the easiest boss in the game; telatively low health, a large hitbox, extremely predictable and avoidable attacks, and he's not immune to his own projectiles. Many players feel silly if they take ''any'' damage to this boss at all, let alone die to him. |

| 421 | * CreepyTwins: When fought as a pair. Identical ''and'' dangerous. |
| 422 | * DegradedBoss: They appear as regular enemies as early as the Caves, and don't even get a health bar. On the other hand, they constantly leave behind damaging trails of creep (as opposed to only doing so when charging) and shoot six-way blood bursts rather than spawning flies, making them actually slightly ''more'' dangerous than the boss version. |
| 423 | * DualBoss: They always appear as a pair. Yellow Champion Gurglings have three faster ones appear, but they don't leave creep behind or spawn flies. |

| 444 | * AdorableEvilMinions: His Dips. |
| 445 | * BullfightBoss: One of his attacks is to charge at you three times in succession, occasionally leaving a pile of poop on the first charge. He scrunches up just before the charge and gets pooped (heh) after the third charge, allowing you to get damage in. The Red Champion version charges four times but slower and shorter, the Black Champion version charges only once at much greater speed, and Dangle charges twice and leaves slippery brown creep. |

| 487 | * WaveMotionGun: In his second phase, he'll fire Brimstone downwards as he strafes along the top of the screen. It has minimal telegraphing compared to most Brimstone attacks, so stay on your toes.

| 516 | \ |
| 517 | A mischievous baby imp that attacks Isaac by using pitfalls, Dark Balls, and Troll Bombs. |
| 518 | ---- |
| 519 | * DegradedBoss: Fittingly, he can be encountered as a boss enemy in Sheol onwards and the Chest. |
| 520 | * DualBoss: Double Trouble boss rooms can contain Little Horn paired with Rag Man, Loki, The Fallen, or Big Horn. |
| 521 | * EnfantTerrible: Appears to be a baby version of Big Horn. |
| 522 | * GetBackHereBoss: Spends a lot of the fight teleporting away from the player, often leaving a Troll Bomb behind. He also flees from the player if approached. |
| 523 | * HomingProjectile: He fires large homing projectiles that will track you forever until you destroy them with your own attacks. |
| 524 | * PlayingWithFire: Orange Champion Little Horn spits out burning Troll Bombs instead of the black homing projectiles, which deal contact damage and leave behind a damaging fire upon detonation. |
| 525 | * PortableHole: Can make these to teleport himself around the room, teleport Troll Bombs around the room, or to send straight at you so that you will fall in and take damage. |
| 526 | * RedEyesTakeWarning: Despite appearing cute, his red eyes are a hint that he wants to play with Isaac violently. |
| 527 | * ScrewThisImOuttaHere: When his health gets depleted, instead of dying, he retreats into one of his portable holes. |
| 528 | * TacticalSuicideBoss: Has a tendency of teleporting into his own Troll Bombs that can shave off half of his health bar until the 1.7.8a patch of ''Repentance'', after which they do much less damage to Little Horn. The boss room also tends to have fires, which Little Horn will run into and burn himself to a crisp if you herd him in that direction. |
| 529 | * ThinkingUpPortals: Can open up two holes that are linked to each other, either to teleport itself around the room or as a lead-up to the following trope. |
| 530 | * ThrowDownTheBomblet: Attacks with Troll Bombs by opening a pair of portals between his location and the player and throwing one in. |
| 531 | * TooDumbToLive: [[TacticalSuicideBoss Just to reiterate]] — Little Horn has a tendency to deploy Troll Bombs [[ExplosiveStupidity that blow up in his face]]. But that can be chalked up to recklessness rather than complete stupidity, since the bombs are haphazardly scattered around the room. What ''really'' cements this trope is Little Horn being [[LongRangeFighter so committed to keeping his distance]] that [[BossArenaIdiocy he can be tricked into bumbling into a fireplace and burning himself to death]]. |

| 541 | A giant fly that bounces around playfully while firing loads of projectiles against Isaac, but will reward him if spared. |
| 542 | ---- |
| 543 | * AscendedGlitch: Patch 1.7.9 introduced a new death animation for Baby Plum as part of the [[ProductPlacement G-Fuel themed daily challenge]], where a poorly-cropped missile will fly down and blow her up when defeated. However, this death animation was accidently set to trigger outside of the daily challenge. In the subsequent 1.7.9a patch, this death animation was changed to have a 0.0001% chance of occurring during normal gameplay. |
| 544 | * BigCreepyCrawlies: She's a giant fly. |
| 545 | * BulletHell: Very mild compared to most examples in the game (especially the final bosses), but she shoots a ''lot'' of projectiles for a boss you can fight on the first floor. |
| 546 | * DegradedBoss: Appears as a boss enemy in Cathedral onwards. |
| 547 | * KaizoTrap: Fires a ring of 10 projectiles after being killed. |
| 548 | * KingMook: Of various flies, most notably the Red Boom Flies. |
| 549 | * SheatheYourSword: If you don't attack her and survive her attacks, she'll happily fly off after waving and drop the Plum Flute, an active item which summons her for help.

| 583 | A massive leech that tunnels out of the ground, tearing its boss room apart in the process. |
| 584 | ---- |
| 585 | * BossArenaUrgency: It can punch holes in the floor with its tail. Given the way pits work in this game, this won't kill you, but it does make it more difficult to dodge Wormwood's attacks and gives it more places to ambush you from. |
| 586 | * DeadlyLunge: Gains a ''very'' fast one when it's at low health. |
| 587 | * FeedItABomb: Place a bomb while it's chasing you and it will swallow the bomb, taking huge damage from the explosion. |
| 588 | * FlunkyBoss: Two small leeches |
| 589 | * KingMook: To the leech enemies found throughout the game, but especially the Small Leeches in Downpour. |
| 590 | * MakingASplash: Its projectiles appear to be water, as opposed to the standard blood projectiles. |
| 591 | * MeaningfulName: Named after the biblical [[https://en.wikipedia.org/wiki/Wormwood_(Bible) Wormwood]], a star which will fall and turn a third of Earth's waters bitter and deadly. |

| 621 | A flame ghost possessing the body of the Husk, who commands a swarm of Willos. After the Husk's body is destroyed, she dives underwater and comes up only to attack. |
| 622 | ---- |
| 623 | * DemonicPossession: She's a small flame ghost possessing the body of the Husk. |
| 624 | * {{Foil}}: To Lil Blub. Lil Blub is basically the Duke of Flies, still alive, but drowned and bloated and still using attacks similar to his first form, with the addition of jumping up and down to spray water bullets everywhere. Min-Min, by comparison, just uses the Husk's body to protect itself while summoning flies in ways that are different from the Duke and the Husk, and once the body takes enough damage, she quickly dumps it in exchange for using the water to hide herself. |
| 625 | * GetBackHereBoss: In her second phase, she constantly ducks underwater and summons Willos for Isaac to dodge. |
| 626 | * KingMook: To the Willo Flies found in the Downpour. |
| 627 | * MeaningfulName: Named after the Min Min lights, a phenomenon in Australia where unexplained lights are reported to follow people at night. |
| 628 | * MookMaker: Her first phase involves surrounding herself with Willos that you need to clear away. Her second phase also has her summon mass numbers of Willos, but only to shoot once before disappearing. |
| 629 | * SequentialBoss: First you fight her Husk shell. Once that's destroyed, you have to kill the ghost herself. |
| 630 | * UndergroundMonkey: Zig-zagged. As a Willo-like boss using the Husk's body, you'd think she'd use the Husk's attacks too. While she does summon flies, said flies are used in ways the Husk never did, Min-Min always approaches Isaac instead of bouncing everywhere, and getting Min-Min down to half health makes her ditch the body entirely. |
| 631 | * WreathedInFlames: Strangely for the boss of a water-themed level. She's meant to be a WillOTheWisp, so the fire makes some sense. |

| 696 | * BodyHorror: It's named for a real-life chunk of BodyHorror in which organs try to absorb each other. |

| 735 | * EyeScream: It detaches its eyeballs when its HP starts getting low. They block your shots and will inflict CollisionDamage on you if you touch them. Oh! And [[EyesAreUnbreakable they're indestructible]] until you kill their original owner (unless you use Chaos Card or have the Little Horn, Euthanasia, or God's Flesh passive items). |

| 741 | * HeelFaceTurn: Not the boss itself, but The Peeper item gives you a floating eyeball familiar that moves the same way as Peep's eyes. |
| 742 | * KevLard: A FatBastard with good HP. |
| 743 | * MeaningfulName: His name, Peep, could be a reference to several things. |
| 744 | ** Pronounce the second "p" as though you were saying the letter "p". He can also attack you with [[UrineTrouble pee-pee]]. |
| 745 | ** There's also the fact that "peep" can mean to look at something, and he attacks you with his eyes. It could also be reference to the term "peeper" which is an informal term for an eye. |
| 746 | * PsychopathicManchild: He gives some of these vibes. While Peep seems to be an adult, he sorta acts like a CheerfulChild during his boss fight and he throws a fit after being defeated. |
| 747 | * TurnsRed: When he loses 2/3rd of his HP, one of his eyes detaches and it begins acting as an obstacle. His other one does the same when he's left at 1/3rd of health. Averted with his Cyan Champion variant, who starts the fight with both of his [[{{Pun}} peepers]] detached. |

| 808 | * DualBoss: The Blue Champion variant is two smaller Gurdy Jr.'s, who only attack by charging. |
| 809 | ** Two Gurdy Jr.'s can appear in a Double Trouble boss room in the Depths. |
| 810 | * HeelFaceTurn: The Lil' Gurdy item gives you an even smaller version of this boss, who uses her charging attack. |
| 811 | * MetamorphosisMonster: She appears to be the second stage of the Gurdy line. |
| 812 | * MissingSecret: Before '"Wrath of the Lamb'' version 1.2, she would only appear as a DegradedBoss due to a bug. |
| 813 | * MookMaker: She can summon a Pooter during her boss battle. |
| 814 | * {{Nerf}}: In ''Rebirth'', Gurdy Jr. was moved from the Cellar to the Caves due to being much harder than other Chapter 1 bosses. She effectively traded places with Fistula. |
| 815 | * ShedArmorGainSpeed: Being smaller than the standard Gurdy means that she's able to actually move, albeit by oozing so much viscera that she can slide around with her momentum. |

| 1071 | * BigBrotherInstinct: He rather fiercely protects his younger kin, Little Horn. The eponymous passive item causes Big Horn to extend this protection to Isaac as well. |
| 1072 | * DamageSpongeBoss: Not as tanky as Mega Fatty, but still on the high end. His constant teleporting doesn't help. |

Evidently, [[spoiler:Dark Esau]] is so dangerous that even demons like Big Horn try to keep him contained. |
| 1075 | * FeedItABomb: When his mouth opens, you can kick a bomb into it. This will stun him for a bit and cause him to take 20% more damage for the duration of the stun. |
| 1076 | * FlunkyBoss: A downplayed example. During Big Horn's boss fight, he occasionally summons Little Horn as a DegradedBoss, not that he summons anyone else. |
| 1077 | * GetBackHereBoss: Ducks underground constantly, then reappears somewhere else in the room. |
| 1078 | * HeelFaceTurn: The "Little Horn" passive item has Big Horn assist Isaac, by sticking his hand out to crush or slap enemies. |
| 1079 | * MiniBoss: In ''Afterbirth†'', he can summon a significantly weaker version of Little Horn during the fight. ''Repentance'' changed this to instead have Little Horn sitting on one of his hands to spit out a few Dark Balls and leave. If Big Horn runs out of health and retreats during this, however, Little Horn will jump down and fight with a tiny health bar. |
| 1080 | * PortableHole: He creates two or three holes around the room as his main attack, which either expands to become pitfalls or his hands will stick out and either throw bombs or chase the player. His head is also sticking out of one. |
| 1081 | * RoarBeforeBeating: Can be heard growling in his versus screen. |
| 1082 | * ScrewThisImOuttaHere: Once defeated, he retreats into his hole. |
| 1083 | * SiblingTeam: Becomes this with Little Horn in ''Repentance'', which makes it clear that Big Horn is supposed to be an older brother to Little Horn. Rather than summoning Little Horn to fight, Big Horn keeps him protected so he can fire out Dark Balls, though Little Horn will join the battle if Big Horn falls during this. The item named Little Horn, which gives the player a single horn similar to the ones Little Horn has, causes Big Horn to assist them by crushing enemies. |

| 1103 | * MoneyFetish: He loves coins, and will instantly ignore Isaac to pick up any coins on the ground. |
| 1104 | * PunnyName: With a mix of BilingualBonus. "Bambino" is Italian for child, so Bumbino is a child Bum-bo. |
| 1105 | * ShoutOut: In a weird recursive way to ''The Legend of Bum-bo'', which is technically a prequel to ''The Binding of Isaac'' based on a BreakoutCharacter... Regardless, all of his attacks, animations, and sound effects are based on the Bum-bo game more than the actual Bumbo item. |
| 1106 | * SoreLoser: When defeated, he starts crying and throws a mini-tantrum. |

| 1116 | \ |
| 1117 | A little devil that rides around in a minecart, travelling between doors while throwing bombs at Isaac. Once his health has been depleted, he drops out of his cart and Isaac has a chance to kill him for extra bombs or an item. |
| 1118 | ---- |
| 1119 | * BigRedDevil: He only has one horn, but otherwise he looks like a stereotypical demon. |
| 1120 | * BlowingARaspberry: Will occasionally stick his tongue out at you instead of attacking. |
| 1121 | * BoobyTrap: His decoys are trapped to burst into troll bombs if destroyed. |
| 1122 | * BrattyHalfPint: He's meant to come off this way. His initial working name was even "Little Shit". |
| 1123 | * CartoonBomb: Most of his bombs resemble the typical grey ball with a fuse, but his Brimstone bombs have a different, more "high tech" design. |
| 1124 | * CentrifugalFarce: In one of his attacks he rides around the same section of track in a loop, until he makes himself dizzy and throws up. |
| 1125 | * CheshireCatGrin: He wears a mischeivous grin up until the point where you destroy his minecart. |
| 1126 | * CombatPragmatist: He deliberately tries to trick and distract you, uses attacks that deal twice as much damage as most other bosses, and when he's beaten, he tries to escape rather than just letting himself be killed. |
| 1127 | * ConfusionFu: Hornfel's attacks are erratic and unpredictable, especially when combined with other factors like the decoys and enemies arriving on carts. Beating him requires less rote memorization of attack patterns and more of an ability to react to a quickly changing environment. |
| 1128 | * DrearyHalfLiddedEyes: His eyes are somewhere between this and TsurimeEyes. |
| 1129 | * EnemyPosturing: He'll sometimes stop attacking just to stick his tongue out at you. |
| 1130 | * EnfantTerrible: An implied example. While his age isn't confirmed, his immaturity and small size makes him come across as quite young. Regardless of his age, however, he still clearly wants you dead. |
| 1131 | * EvilIsBurningHot: He can shoot incendiary bombs or {{Fireballs}} at you. |
| 1132 | * FangsAreEvil: Has prominent fangs which are visible at nearly all times. |
| 1133 | * {{Fireballs}}: In one of his attacks, he pukes up a fireball that spreads across the floor in a cross-pattern. |
| 1134 | * FlunkyBoss: Sometimes appears with a couple of fly bombs. Other enemies in carts also appear randomly throughout the fight. |
| 1135 | * FragileSpeedster: He only has 240 HP, less than some Basement bosses. But his minecart makes him move very quickly and erratically, and so he still takes a while to kill. |
| 1136 | * GetBackHereBoss: In his second phase, he stops attacking and runs for the exit. You don't have to kill him to win the fight, but you get some extra bombs if you do. |
| 1137 | * GlassCannon: His HP is low[[note]]he has 240 HP[[/note]], but most of his attacks do a full heart of damage. |
| 1138 | * GreenAroundTheGills: He briefly turns green when nauseous. |
| 1139 | * HoistByHisOwnPetard: One of his attacks has him riding around and around the same section of track, making him sick and vulnerable to attack. |
| 1140 | * HornsOfVillainy: Well, only one horn. |
| 1141 | * InelegantBlubbering: A downplayed example, but [[VillainousBreakdown he does some crying when you destroy his mine cart]]. |
| 1142 | * IronicName: He's named after a [[https://en.wikipedia.org/wiki/Hornfels type of rock known for being tough and durable]], so you'd expect him to be a StoneWall rather than a FragileSpeedster. |
| 1143 | * KnowWhenToFoldEm: After you break his minecart, he realizes that he can't beat you and runs for the exit. |
| 1144 | * LaughablyEvil: Hornfel displays a lot more personality than most bosses. In particular, his tendency to do silly things like taunting you, accidentally making himself sick, and bursting into tears when defeated makes him quite engaging. |
| 1145 | * MadBomber: His main modus operandi is to ride around on his minecart, chucking various bombs at you. |
| 1146 | * MadeOfIncendium: Why exactly his vomit explodes is a mystery. |
| 1147 | * MinecartMadness: Inverted. He's the one on the minecart, but you're still the one doing the dodging. |
| 1148 | * OutfitDecoy: Can send out decoys in carts that burst into troll bombs when hit. |
| 1149 | * PintSizedPowerhouse: He's much smaller than most bosses, being about the same size as Isaac. However, he's just as dangerous (if not more so) than many bosses that are at least five times larger than he is. |
| 1150 | * PlayingWithFire: Can spit fireballs and sometimes uses incendiary bombs. |
| 1151 | * ProneToVomiting: He seems to get motion sick easily. Both on his own and as part of The Horny Boys, he ends up throwing up from moving too fast. |
| 1152 | * ScoobyDoobyDoors: His boss room is lined with them, and Hornfel can emerge from any one at any time. However, the player can't use them. |
| 1153 | * ScrewThisImOuttaHere: Depleting Hornfel's health destroys his minecart, at which point Hornfel will run for the nearest door. This makes Hornfel one of only three bosses that can be defeated non-lethally[[note]]the others being Baby Plum and Bumbino[[/note]], but you do get a few bomb pickups or even a bomb-based item, as well as unlocking an item, if you can kill him before he escapes. |
| 1154 | * SequentialBoss: Technically has two phases with separate health bars, though the second phase just consists of him running away. |
| 1155 | * SheatheYourSword: He can be defeated non-lethally by letting him escape during his second phase. Unlike Baby Plum and Bumbino, you're rewarded for killing him rather than letting him go. |
| 1156 | * ShoutOut: The Brimstone bombs he uses are visually based on the grenades launched by the Iron Bomber, an unlockable weapon in ''VideoGame/TeamFortress2'' which was originally designed and submitted to the Steam Workshop by Kilburn (one of ''Antibirth''[='=]s creators). |
| 1157 | * SuperSpit: His main non-bomb attack has him continually speeding up on his minecart, only to end up going so fast that he gets sick and [[VomitIndiscretionShot projectile vomits in your general direction]]. The puke, of course, explodes. |
| 1158 | * ThrowDownTheBomblet: All of his attacks bar one are bomb-based. Even his vomit explodes into fire. |
| 1159 | * TrickBomb: Hornfel's bombs use several different modifiers: he can throw Hot Bombs which leave damaging fire behind, Rock Bombs which send rock waves in the cardinal directions, and a unique Brimstone bomb that explodes into a four-way Brimstone laser. |
| 1160 | * TsurimeEyes: Has these to highlight his cocky attitude, but they change to circular once his cart breaks and he starts panicking. |
| 1161 | * TurnsRed: Inverted. In his second phase, he stops attacking completely and [[ScrewThisImOuttaHere just tries to run away]]. His contact damage is also reduced from a full heart to half a heart. |
| 1162 | * WaveMotionGun: His Brimstone bombs fire beams in the cardinal directions. |
| 1163 | * VehicularAssault: Attacks from a minecart which you have to destroy to defeat him. |
| 1164 | * VillainousBreakdown: He begins freaking out once Isaac destroys his minecart. |
| 1165 | * VomitIndiscretionShot: One of his attacks has him vomit up a fireball that explodes in the cardinal directions. |

| 1180 | * FireBreathingWeapon: One of Gideon's attacks has it spewing fiery bullets down the middle of the room, which will leave lingering fires on the ground. It also exploits this by summoning a number of enemies that [[InfernalRetaliation become more powerful when lit on fire]]. |
| 1181 | * KingMook: To the Grimaces, using a mix of different skills from quite a few of them. |
| 1182 | * MookMaker: Summons six waves of enemies to attack you in addition to shooting at you himself. Defeating all of the minions ends the fight. |
| 1183 | * MultiMookMelee: You have to fight 6 waves worth of enemies before the fight is finished. |
| 1184 | * NamedAfterSomebodyFamous: Shares his name with a prophet and military leader from the Old Testament who is said to have defeated an overwhelming army of Midianites with only 300 Israelite soldiers. |
| 1185 | * NighInvulnerable: Like the [[InvincibleMinorMinion enemies]] he's based on, Great Gideon is immune to everything that's not a Chaos Card, and you defeat him (without actually killing him) by killing all of the other monsters in the room. |
| 1186 | * NonLethalKO: Instead of exploding into gore like most bosses, he turns off after you defeat his MultiMookMelee. You can subvert this using the [[OneHitKill Chaos Card]], which causes him to explode into pebbles. |

| 1198 | ---- |
| 1199 | * BossArenaIdiocy: The Tuff Twins start out covered in a rock shell that makes them impervious to attack and must be broken with explosions. Their boss room always happens to contain a number of Bomb Grimaces that provide free bombs to chuck at them, and occasionally a couple of TNT barrels as well. |
| 1200 | * BrokenArmorBossBattle: Their hard shells must be destroyed with explosions before your tears are able to damage them. |

| 1253 | * ArtShift: Clutch has a notably scratchier art-style than anything else, implying that he's some sort of outside force possessing his way into the game. |

| 1256 | * BlackEyesOfCrazy: His eyes are completely black save for two small purple pupils. |

| 1261 | * PlayingWithFire: In his second phase, Clutch spews waves of purple fire around the room. |

| 1297 | * TheArtifact: The Pile was made for ''Antibirth'' back when Polycephalus didn't have an UpgradedBoss variant in the official game. This was rectified in ''Afterbirth'' with the Stain, but the Pile still got added into ''Repentance'', making Polychephalus one of two bosses (the other being the Haunt) with two undead versions. As fights, however, the Stain and the Pile are different enough from each other to both fit in. |

| 1370 | * DegradedBoss: Appears as a boss enemy only in the Dark Room. |
| 1371 | * EarlyBirdCameo: It's possible to encounter Gish in the Void even before he's unlocked, as unlocking him requires beating Chapter 3 20 times while the Void can be unlocked much earlier. |
| 1372 | * FlunkyBoss: Can sometimes be fought alongside Clotties. |

| 1374 | * KingMook: To the Clots. |
| 1375 | * MookMaker: Spawns Clots on his second jump attack. |
| 1376 | * UndergroundMonkey: An alternate version of Monstro II that can be encountered in the Depths and Dank Depths. This makes him the only alternate version of a posthumous boss as he was present in the original game alongside Monstro II. |

| 1388 | * AllInTheManual: As stated in the bestiary, the heart is called Heart of Infamy. |
| 1389 | * AttackItsWeakPoint: The mask is invincible until you destroy her heart. Even after that, you need to hit her from behind. |
| 1390 | * CatAndMouseBoss: The first phase of the fight: you chase the heart, while the mask chases you. |
| 1391 | * ChasingYourTail: The second phase of the fight has you trying to attack the mask's vulnerable rear, while she continues to try and run you down. |
| 1392 | * DegradedBoss: Appears as a boss enemy only in the Dark Room. |
| 1393 | * FemaleMonsterSurprise: The Mask is female, as confirmed by Edmund. |
| 1394 | * InterfaceScrew: The only boss without a health bar in the original version, though fixed in ''Rebirth''. The fact that it's not easy to land a shot in the last stage made the fight look depressingly long. |
| 1395 | * KingMook: A beefed-up version of the Mask + Heart enemies also added in ''Wrath of the Lamb''. Her second phase behaves much like a faster version of the Knight enemies. |
| 1396 | * MeatPuppet: A face can be seen peering out from Mask of Infamy's back in her second phase. |

| 1411 | ---- |
| 1412 | * BlackoutBasement: Can turn the screen dark for his attacks. |
| 1413 | * BodyHorror: Noticeably downplayed compared to the other posthumous bosses. Whereas the other ones looked decidedly mangled, warped, or just plain ugly (or uglier), the Adversary… is just missing a horn and is covered in bandages. Even then, he's still recognizably intact. At least, until he starts opening his torso to reveal that basically his ''entire ribcage'' has been replaced with a nest of spiders, and the bandages are coiling around what remains of his innards. |
| 1414 | * BreathWeapon: He can now shoot Brimstone in any cardinal direction, but don't think you're safe if you stand at a diagonal, because it curves towards you. |
| 1415 | * TheComicallySerious: Despite looking a bit sillier than the other posthumous bosses, it looks like he's taking things ''more'' seriously now than he did as Dark One. |
| 1416 | * DegradedBoss: Appears as a boss enemy in Sheol onwards and the Chest. |
| 1417 | * DishingOutDirt: He can jump up in the air and slam down, creating a circular wave of rocks around him. |
| 1418 | * EvilCounterpart: Possibly one to Azazel; both are red-eyed demons with black skin who have a broken horn and use Brimstone attacks. However, while Azazel is a non-villainous PlayerCharacter, The Adversary is a boss. |
| 1419 | * LetsGetDangerous: Its expressions in the first fight make it seem as if he was toying with you. Now that doing that has gotten him injured, he's decided to stop playing around with single-direction attacks. |
| 1420 | * MeaningfulName: The Adversary is one of the ways Satan's name can be translated from Hebrew. |
| 1421 | * MoodWhiplash: Compared to the other posthumous bosses, the Adversary is pretty goofy. The only comparable one is Lokii, and he at least comes from an already cartoony boss. And yes, the dark and edgy name only makes him funnier. |
| 1422 | * MookMaker: Occasionally spawns spiders from [[TorsoWithAView the hole in his chest]]. |

| 1458 | ---- |
| 1459 | * BulletHell: Red Champion Gate has an alternate set of projectile attacks that are considerably much more difficult to dodge due to their unusual patterns. |

| 1461 | * DualBoss: Double Trouble boss rooms can contain The Gatepaired with another Gate in Womb, Utero, and Scarred Womb. |

| 1463 | * MeatPuppet: A pair of eyes can be seen whenever The Gate opens his mouth. When defeated, something that looks like a tiny Isaac peeks outside a crack right before expiring. Red Champion Gate has a demon inside him that can be seen when he is killed. |
| 1464 | * MookMaker: Spawns a series of Leapers in order to set up his Brimstone attack. |
| 1465 | * ReflectingLaser: One of his attacks is to spawn three Leapers and then fire a Brimstone laser that connects between the three and deals a whole heart of damage. Killing the Leapers before he fires it causes the beam to simply travel straight down instead. Interestingly, the effect isn't just limited to Leapers - if the Gate spawns with other enemies (e.g. Greed Mode and Boss Rush), the laser chains to those enemies as well and will most likely kill them for you. |
| 1466 | * StationaryBoss: Just like its living counterpart. |

| 1480 | * AbnormalAmmo: Corn. |
| 1481 | * BulletHell: Tends to fire much larger volleys of projectiles than most bosses. Also drops Corn Mines that explode into even more projectiles. |
| 1482 | * CompanyCrossReferences: Shares its name with a boss from ''VideoGame/SuperMeatBoy'', another Edmund [=McMillen=] game, who also happens to be made of poop with corn in them. |
| 1483 | * DegradedBoss: Appears as a boss enemy only in the Chest and Dark Room. |
| 1484 | * EarlyBirdCameo: It's possible to encounter Brownie in the Void even before it's unlocked, as unlocking it requires beating the Chest 3 times while the Void can be unlocked much earlier. |
| 1485 | * HopelessBossFight: Because Butt Bombs heal Brownie instead of damaging it, encountering it during the Beans! challenge will almost certainly end the run if Isaac has no other means of attacking. The same is true in Hot Potato if you were (un)lucky enough to find Butt Bombs. |
| 1486 | * ImmuneToBullets: Using Butt Bombs against Brownie will heal it instead of damaging it. |
| 1487 | * MookMaker: Spawns Brownie Corns in large numbers throughout the fight. |
| 1488 | * OneHitKill: Using Flush! will instantly kill him and any Brownie Corns, without him turning into Dangle. |
| 1489 | * RushBoss: Although its attacks and minions can be difficult to dodge, Brownie doesn't have a particularly large health pool. The fact that one of its attacks is essentially CastFromHitPoints doesn't help its case. |
| 1490 | * TacticalSuicideBoss: The exploding turds Brownie places down can not only damage it, they can also ''poison'' it. Zig-zagged in that Brownie also trails poisonous creep while poisoned. |

| 1506 | * BadBoss: If you don't destroy them first, she hurls the familiars she summons at you after a set amount of time. |
| 1507 | * BeatTheCurseOutOfHim: If she steals one of your familiars, you can get it back by shooting it. |
| 1508 | * BulletHell: Like a number of other bosses, The Siren can unleash a dense array of bullets in all directions. Her shots actually curve in the air, making them harder to dodge. |
| 1509 | * CharmPerson: Her singing can lure your familiars over to her side. |
| 1510 | * EvilCounterpart: To Lilith, as they are both female demons who specialize in summoning familiars to fight for them. |
| 1511 | * {{Expy}}: Of, oddly enough, the Gorgun from ''VideoGame/EnterTheGungeon'', having several similar attacks and a similar appearance. |
| 1512 | * NotQuiteDead: In ''Antibirth'', if she stole an extra life familiar like Dead Cat or 1up!, she would use it to bring herself back with 10% health and [[BanditMook eat the extra life in the process]]. This feature was removed in ''Repentance''. |
| 1513 | * NumberOfTheBeast: She has exactly 666 HP. |
| 1514 | * OurSirensAreDifferent: Rather than a traditional alluring fish woman or even a mythologically-accurate bird woman, this Siren is a demon. She's closer to a PG [[SuccubiAndIncubi succubus]] than something you'd normally refer to as a siren. |

| 1529 | ---- |
| 1530 | * TheArtifact: Similar to the Pile, the Heretic was created to be a [[UpgradedBoss harder]] UndeadCounterpart of the Haunt in the ''Antibirth'' mod. Thanks to the presence of the Forsaken in ''Afterbirth'', The Haunt now has two very different undead(er) versions, all encounterable in separate chapters. |
| 1531 | * BackFromTheDead: Also like the Pile, the Heretic can be seen as the "third stage" in a sequence of decay from the original boss, considering how his skeleton looks. |

| 1536 | * OneHitKill: Like with all ghost bosses, using Vade Retro when he's at 50% or less health will kill him instantly. |
| 1537 | * OurGhostsAreDifferent: And apparently more undead. |

| 1552 | ---- |
| 1553 | * AdaptationDeviation: The Visage is the only boss from ''Antibirth'' to not appear in its original floor, the Mausoleum; instead only appearing in Gehenna. Its appearance has changed from purple flames to red flames to reflect this. |
| 1554 | * AdaptationDyeJob: In ''Antibirth'', its flames and heart were purple to match the Mausoleum. Since it was moved to Gehenna, it was changed to red in ''Repentance''. |
| 1555 | * AttackItsWeakPoint: Initially, it's the chain holding the two together; afterwards, the heart itself becomes the weak point, and the mask can be incapacitated by attacking it from behind. |
| 1556 | * TheArtifact: Still shoots purple EyeBeams despite its eyes being changed to red. |
| 1557 | * CatAndMouseBoss: As with Mask of Infamy, the heart flees while the mask tries to run you down. The difference is that the heart is fully capable of fighting back, and the mask doesn't like to stay dead. |
| 1558 | * DualBoss: As opposed to the original Mask of Infamy, which is taken down one part at a time, both parts of The Visage attack simultaneously, and even come with a number of {{Combination Attack}}s. |
| 1559 | * GrapplingHookPistol: The Visage's heart can use chains to pull itself to nearby surfaces. Note that this includes the mask and ''[[YouWillNotEvadeMe Isaac]]''. |

| 1574 | * BodyHorror: It's Loki and Hornfel turned into ConjoinedTwins by stitching their bodies together. They seem to be alright with it, though. |
| 1575 | * BulletHell: One attack has Loki sending out a bullet pattern which is considerably more complex than the one he uses when he's by himself. |
| 1576 | * CombinationAttack: They're built for this, fusing mechanics from their separate boss encounters. For example, Loki can use his teleportation while Hornfel throws bombs. When Loki summons a Boom Fly, it'll have a few bombs orbiting it. When Loki does his GroundPound bullet spray, he starts doing it faster and faster until Hornfel gets sick and coughs up incendiary bombs. |

| 1592 | * PowerFloats: They constantly hover above the ground. |

| 1594 | * SmokeOut: They can teleport rapidly around the room while dropping smoke bombs. |
| 1595 | * SuperSpit: Hornfel has incendiary vomit, though he only seems able to use it by accident. |

| 1600 | * TricksterTwins: Both of them clearly love working together in being as obstructive as possible with their combined skills. |
| 1601 | * {{Troll}}: Judging by his expression, Loki seems to enjoy forcing Hornfel to use the bullet spray attack against his will. |

This is one boss you'll ''always'' want to attack from the back, even more so than Mask of Infamy[[note]]which, may we remind you, ''is invulnerable from the front''[[/note]]. |
| 1622 | * EyeScream: His eyes are covered in red growths, and aren't attached to him. |
| 1623 | * FatBastard: Infamously moreso than his living version. |
| 1624 | * HitboxDissonance: [[https://bindingofisaacrebirth.gamepedia.com/The_Bloat The official wiki]] states that there is a glitch with The Bloat's floating eyes having the same collision radius as his main body, making the eyes harder to evade as the hitbox does not match up with the eyes' visual size. This may have been a contributing factor to his hated status before it was mercifully fixed in ''Repentance''. |
| 1625 | * KevLard: A FatBastard with a fairly high amount of HP. |
| 1626 | * MeaningfulName: "Bloat" is the medical term for abdominal distention, and he is a FatBastard. Could also be attributed to the fact that he's the rotting corpse of Peep (i.e. "bloated corpse"). |
| 1627 | * PoisonousPerson: Green Champion Bloat leaves green creep and fires Ipecac shots. |
| 1628 | * RecurringBoss: You fight him on ''every floor'' in the Aprils Fool challenge. |

| 1639 | A pair of giant Vis. They roll around and occasionally stop to fire a gigantic Brimstone beam or bullet spray towards each other. When one sister dies, the other turns red and becomes much faster and more dangerous. |
| 1640 | ---- |
| 1641 | * TheCameo: Originally appeared as bosses in Edmund's earlier game, ''Gish''. |
| 1642 | * DistaffCounterpart: To The Cage. They're female and look almost identical to him, except they have heads. They were also supposed to debut in ''Afterbirth'', but were cut and replaced with the pink Champion Cage (which is, of course, two Cages). |
| 1643 | * DualBoss: Sisters Vis spawns in pairs by default. Can come in as many as eight at once in Greedier Mode. |
| 1644 | ** Double Trouble boss rooms can contain a Sisters Vis paired with Larry Jr., The Husk, or Lokii. |
| 1645 | * EarlyBirdCameo: It's possible to encounter Sisters Vis in the Void even before they're unlocked, as unlocking them requires beating The Chest with six different characters while the Void can be unlocked much earlier. |
| 1646 | * GiantMook: A pair of giant Vis, although they don't really look like them. |
| 1647 | * RollingAttack: Just like The Cage, with one of them leaving [[PoisonousPerson green creep]] and the other leaving [[ToiletHumor brown creep]]. |
| 1648 | * TurnsRed: When one Sister is killed, the other will literally turn red and begin moving faster. |
| 1649 | * WaveMotionGun: Much like the Vis enemies, their main attack is opening up their stomach and firing blood lasers similar to Mega Satan's blood laser. They usually do it facing towards each other, but if one does it alone (or the other one is dead), they will sweep it left to right. |

| 1660 | A colossal zygote that hops around and sprays shots at Isaac. It splits into two smaller cells on death, which split in two again, then each leave a harmless Embryo on the ground. |
| 1661 | ---- |
| 1662 | * AsteroidsMonster: As it gets damaged, it splits into smaller blobs. The smallest blob variety leaves behind the Embryo inside when destroyed. |
| 1663 | * BlobMonster: Judging by the name, it's a gigantic, blob-like cell. |
| 1664 | * BulletHell: Can happen if too many of them are left onscreen. Since they only fire in a set direction, however, it's pretty tame compared to most other examples in the game. |
| 1665 | * DegradedBoss: The Embryo form can appear as early as the Basement, and the medium-sized form can be encountered in the Womb and Scarred Womb before the boss itself. Its full form appears as a proper boss enemy in Sheol onwards and the Chest. |
| 1666 | * FakeUltimateMook: Amusingly enough, the helpless Embryos that spawn as regular enemies on early floors had mini-boss health bars in the original game, as the game counted them as Blastocyst. |
| 1667 | * KingMook: To the Embryos found in early stages. |
| 1668 | * MegaMicrobes: They're cells/developing embryos that are bigger than Isaac. |
| 1669 | * WeaksauceWeakness: Poison, at least until ''Afterbirth†''. Normally, a boss would only take a bit of damage from poison, as their health bars reach in the hundreds, but if Blastocyst is poisoned when it divides, it's instantly killed, ending a long boss fight within a few minutes. They got a BalanceBuff in ''Afterbirth†'' that removed the insta-kill, but they still pass debuffs onto their smaller forms when splitting. |

| 1680 | ---- |
| 1681 | * AttackItsWeakPoint: You can only damage it by hitting it in the very back segment. |
| 1682 | * FragileSpeedster: It has the lowest health of any boss in the game, but it makes up for this with its speed and only being vulnerable to damage in one hard-to-hit weak point. ''Rebirth'' gave Scolex a health buff (so it's at least beefier than most of the Chapter 1 and 2 bosses), but it still has notably lower HP than every other Womb boss. |
| 1683 | * MeaningfulName: A scolex refers to the head of a tapeworm. |
| 1684 | * TacticalSuicideBoss: One of its attacks has it poking its vulnerable tail out of the ground for a fairly lengthy period of time before firing three Ipecac shots, giving the player a perfect opportunity to take off a lot of its health. |
| 1685 | * UndergroundMonkey: It's [[UpgradedBoss a much tougher version of Pin]], but unlike the UndeadCounterpart versions of other bosses, Scolex is noticeably different in appearance from its easier version (and was also in the game ''before'' Pin). There also isn't really anything about Scolex's appearance to suggest that it's undead or already maimed, whereas all of the UndeadCounterpart bosses have some degree of death-and/or-injury-related BodyHorror (such as rotting, missing body parts, [[DemBones being skeletons]], being covered in blood, etc.). |

| 1713 | A variation of Daddy Long Legs that only has three legs to stomp with but also leaves slowing white creep while doing so. |
| 1714 | ---- |
| 1715 | * AscendedGlitch: In the first launch of ''Wrath of the Lamb'', it was possible for Triachnid to replace Isaac as the boss of the Cathedral. While the bug was fixed, his unlock method in ''Rebirth'', killing Isaac 10 times, is a reference to this. Daddy Long Legs, whom Triachnid replaces, can also be encountered as a DegradedBoss in Cathedral. |
| 1716 | * TheCameo: Triachnid is a reference to a previous flash game by Edmund [=McMillen=]. Furthermore, Triachnid is an alternate of Daddy Long Legs; in his own game, Triachnid was finding a home for his young. |
| 1717 | * EarlyBirdCameo: It's possible to encounter Triachnid in the Void even before it's unlocked, as unlocking it requires beating Cathedral 10 times while the Void can be unlocked much earlier. |
| 1718 | * GiantFootOfStomping: Shares Daddy Long Legs' stomp attacks, but while Daddy Long Legs has four legs to stomp you with, Triachnid only has three. |

| 1732 | ---- |
| 1733 | * TheArtifact: With the "Double Trouble" mechanic in ''Rebirth'', Lokii is kind of redundant; the fact that the halves summon Red Boom Flies instead of regular Boom Flies and that they're fought in a 1x1 room is the only way they're different from a Double Trouble Loki fight. |
| 1734 | * DegradedBoss: Appears as a boss enemy in Sheol onwards and the Chest. |

| 1737 | * MadeOfBologna: His in-game sprites prior to ''Repentance'' had the two halves cut off with solid red innards. ''Repentance'' averts this, with [[BodyHorror visible guts]] on the cut like his VS artwork. |
| 1738 | * MookMaker: Unlike standard Loki, they summon ''Red'' Boom Flies. This gives them an advantage because they won't be blasted in the face if their minions die near them. |
| 1739 | * TeleportSpam: Just like normal Loki. |
| 1740 | * VisualPun: The last two "i"s of his name have a line crossed through them on the bottom, making them resemble part of the Roman numeral II. |
| 1741 | * UndeadCounterpart: Loki has been split in two, but both halves live on. |

| 1753 | ---- |
| 1754 | * AsteroidsMonster: The same as Fistula, except now filled with spiders instead of Chargers. The biggest difference between them is that Teratoma's largest form splits into three, whereas Fistula splits into four. |
| 1755 | * BodyHorror: Like Fistula, it's named after a real-life phenomenon in which the body forms a growth containing all three germ layers, one of which can potentially manifest as ''bone shards and teeth!'' |
| 1756 | * DegradedBoss: |
| 1757 | ** Teratoma's smaller forms can appear as early as Catacombs, while the full version appears as a boss in Sheol onwards, the Chest, and Corpse. |
| 1758 | ** Teratoma is one of four bosses that can be spawned by It Lives. |
| 1759 | * UndeadCounterpart: Kind of. It's the posthumous version of Fistula in mechanics, although given that both are different real-life tumors without any personality or even attack method, it's hard to to say how "posthumous" they can really be. |

| 1775 | * SuperSpit: One of her moves has her spew orange vomit all over. |

| 1806 | * CompositeCharacter: She's Chub [[EquippableAlly wrapped up]] in a Fistula, although the boss herself doesn't actually use any attack patterns from those two until she takes enough damage, upon which she'll [[DecompositeCharacter essentially fall apart and become them]]. |

| 1869 | * MookMaker: The first phase can vomit out Globin and Glazing Globin goos along with Small Maggots, the second phase can shoot out Attack Flies, and the third phase can shoot out Leeches. |
| 1870 | * SequentialBoss: Has three separate phases. First it's a fight with the creature itself. Once that's defeated, it eats you and you kill a maggot in its gut. Then you kill it by destroying an organ deeper inside that looks suspiciously like a ballsack. |
| 1871 | * StationaryBoss: It can't move in any of its three phases. |

| 1880 | The four HorsemenOfTheApocalypse, unlocked after beating Mom for the first time. Famine, Pestilence, War, and Death each have the ability of replacing one of the bosses of the Basement, Caves, Depths, and [[spoiler:Womb]] respectively, while the Headless Horseman has the capability to replace any of these bosses, and Conquest was introduced as an alternate boss to Death. |
| 1881 | ---- |
| 1882 | * CombatBreakdown: Interestingly, most of the Horsemen actually get ''easier'' in their second phases, usually due to you destroying parts of them. The main exceptions are Famine, who switches to a SpreadShot that isn't much easier to dodge than his charge and Pooters, and Conquest, who never changes behavior. |
| 1883 | ** Pestilence is reduced to spitting Attack Flies after losing his head, whereas his first phase spawns Chargers. |
| 1884 | ** War loses all of his existing attacks after his horse is destroyed, at which point all he does is run at you. And he frequently gets knocked down while you're firing on him, cutting his combat potential even more. |
| 1885 | ** After jumping off his horse, Death's only attack is to spawn Knights which, more often than not, get run over by said horse. The horse itself also follows a much more predictable pattern than his first phase's scythes and Hourglass. |
| 1886 | * DegradedBoss: All four harbringers appear as boss enemies in Cathedral and Sheol onwards. |
| 1887 | * HeelFaceTurn: The 7 Seals item will spawn a lil harbinger familiar that cycles between the five horsemen and spawns locusts based on the current horseman. |
| 1888 | * HorsemenOfTheApocalypse: The very same (except the Headless Horseman). Like many portrayals, Pestilence initially took Conquest's place before Conquest himself was added. |
| 1889 | * OffscreenTeleportation: Most of them charge against you through the screen and return from the other side. Essentially, they're weaponizing the concept of WrapAround movement. |
| 1890 | * QuirkyMinibossSquad: Despite being full bosses in their own right and fought one at a time, they still fit the bill. Their item drops, the Cube of Meat and the Ball of Bandages, become more powerful by collecting more Cubes or Balls from multiple Horsemen, they can be summoned by the Book of Revelations, multiple Horsemen will appear at the same time as normal enemies in later levels, and they're easily recognizable. They also will all appear when fighting two of the final bosses: [[spoiler: Mega Satan and The Beast, the later having the Ultra versions of the horsemen]]. |
| 1891 | * SequentialBoss: With two stages. Except for Conquest and the Headless Horseman, the latter being a DualBoss. |
| 1892 | * SignatureRoar: The Horsemen that charge at you let out a distinctive shout before doing so. |
| 1893 | * UncattyResemblance: Each of the Horsemen's horses look similar to their rider. |

| 1902 | \ |
| 1903 | The first Horseman, Famine floats around spawning Pooters and charges across the screen if Isaac stands horizontally to him. Upon taking enough damage, Famine's horse and body are destroyed, and his floating head fires a triple shot at Isaac. |
| 1904 | ---- |
| 1905 | * BodyHorror: He represents degradation in general, so this is a given. The lack of lips is especially noticeable, making his SlasherSmile all the more deranged-looking. |
| 1906 | * EyelessFace: Downplayed, as he only has small pinpricks in his eye sockets instead of actual eyes, but it's easy to miss. |
| 1907 | * KingMook: His second phase has him fighting similar to a Maw by shooting 3 bullets at Isaac and slowly moving towards him, which could also lead to an inverted version of this trope because Maws start naturally spawning in the caves, which is the next chapter. |
| 1908 | * LosingYourHead: After taking enough damage, Famine's body explodes, leaving only his floating head. He's reduced to just slowly moving around and firing triple shots at you. |
| 1909 | * MookMaker: Creates Pooters. |
| 1910 | * NightmareFace: Famine's face isn't pleasant to look at, to say the least. [[spoiler:His Ultra form somehow has it worse, as he gains a proper EyelessFace and his SlasherSmile seemingly reaches from ear to ear. And when his body is destroyed, the way his head moves as he fires bullets makes it look like he's laughing maniacally even as you kill him.]] |
| 1911 | * ScaryTeeth: His pearly whites are on display, revealing how pointy and dangerous they are. Though he never uses them to attack with. |
| 1912 | * SlasherSmile: Famine has this as his trademark. |
| 1913 | * UpgradedBoss: Blue Champion Famine shoots out bullets instead of spawning Pooters and will veer towards Isaac while charging. In his second phase, he shoots out a bullet spray similar to Monstro's. |
| 1914 | * WarmUpBoss: As the Horseman of the Basement, Famine has the lowest health and simplest attack pattern out of the Harbingers. |
| 1915 | * WrapAround: Famine charges out the side of the boss room and back in through the other side. |

| 1925 | The second Horseman, Pestilence leaves a trail of green creep, creates chargers, and spews explosive green shots that leave creep puddles. His head is destroyed in his second phase, and he spawns flies instead of chargers and fires shots faster but more chaotically. |
| 1926 | ---- |
| 1927 | * ArtisticLicenseReligion: Pestilence is not an official Horseman and was never mentioned in the Book of Revelations, actually making himself and other portrayals of him look more like [=OCs=] than canonical Biblical villains since the canon horsemen are Conquest, War, Famine, and Death. |
| 1928 | * BodyHorror: No eyes, rotting body with swollen parts, filled with explosive, possibly-toxic fluids, and surrounded by maggots and flies. |
| 1929 | * DegradedBoss: Like the other Harbingers, he can be found in later floors as a normal enemy after Womb. He can also be found in Corpse, making him the only Harbinger to be encountered in the alt path. |
| 1930 | * GreenAroundTheGills: His ''entire body'' is sickly green, swollen, and leaking some sort of disease-ridden fluid. So is his horse. |
| 1931 | * IncurableCoughOfDeath: His [[{{Pun}} hoarse coughs]] summon flies. |
| 1932 | * LosingYourHead: Only the body (still riding the horse) remains after the first part, leaving a gaping hole in his neck where it used to be. |
| 1933 | * MadBomber: Will vomit up explosive ipecac shots. |
| 1934 | * MookMaker: Chargers and Spitties at first, Attack Flies later. Black Champion Pestilence will spawn Trites and later Spiders instead. |
| 1935 | * UpgradedBoss: Black Champion Pestilence leaves white creep instead of green creep and fires six bullets instead of ipecac shots. |
| 1936 | * WalkingWasteland: As the personification of disease and toxin, he leaves a trail of creep everywhere he moves. |
| 1937 | * YourHeadAsplode: When entering his second phase, Pestilence's head detonates akin to an Ipecac shot. |

| 1947 | The third Horseman, War alternates between charging across the room and filling it with troll bombs. At half health, his horse is destroyed and he chases after Isaac while occasionally stopping to cry. |
| 1948 | ---- |
| 1949 | * BullfightBoss: After losing his horse, he starts running after you constantly like Lust. He can be momentarily knocked down by hitting him enough. |
| 1950 | * BullSeeingRed: He's red, and his horse has bull horns and charges. |
| 1951 | * MadBomber: One of his attacks drops bombs randomly. |
| 1952 | * OhCrap: After losing his horse, hit him enough times and he'll fall to the ground stunned, with a terrified look on his face. |
| 1953 | * ProneToTears: War bursts out crying after his horse is killed and stops chasing you to cry about it some more after taking more damage. |
| 1954 | * RedIsViolent: His entire body is red, being a personification of violence and hatred. |
| 1955 | * UpgradedBoss: Gray Champion War has more health and is larger, summons two Mega Troll bombs and spawns a Troll bomb when charging, and shoots out six bullets when stunned. |
| 1956 | * WrapAround: Like Famine, his charge takes him out one side of the room and back into the other. He performs his three times instead of once. |

| 1966 | The fourth Horseman, Death spawns scythes that chase after Isaac and uses The Hourglass to slow his movement. In his second phase, he dismounts his horse which charges across the room constantly, while Death spawns Knights. |
| 1967 | ---- |
| 1968 | * DeathsHourglass: A literal example, in that one of his first stage's attacks is to use the Hourglass item on Isaac and slow him down. |
| 1969 | * DualBoss: He hops off his ride on his second stage, which goes on ramming aimlessly while he hovers around spawning Knights. |
| 1970 | * EarlyBirdCameo: Death can appear in the Boss Rush, which otherwise only features bosses from before Chapter 4. |
| 1971 | * TheGrimReaper: The skeletal kind, complete with black cloak and scythes. |
| 1972 | * MookMaker: Creates Knights, or Maws and Leeches with his Black Champion version. |
| 1973 | * RedEyesTakeWarning: His Black Champion form has glowing red eyes in his sockets. |
| 1974 | * ShoutOut: One of his attacks is very similar to one that [[Franchise/{{Castlevania}} a certain other Death]] you may know of uses. |
| 1975 | * SinisterScythe: He can summon flying, spinning scythes to attack. |
| 1976 | * VisualPun: His champion form is [[TheBlackDeath black]]. Reinforced by the enemies summoned by the champion version: the Red Maws summoned by the first form reference the swelling caused by the disease, while the Kamikaze Leeches refer to the use of leeches as a treatment for the blood build-up. |

| 1986 | The forgotten Horseman, Conquest occasionally replaces Death (War in ''Wrath of the Lamb''). He only has a single phase, and he switches between calling down beams of light or leaving the room and creating an army of clones that all charge at Isaac. |
| 1987 | ---- |
| 1988 | * BeCarefulWhatYouWishFor: Some players complained that War was "too easy" for a boss in the Depths. |
| 1989 | * BlindfoldedVision: Despite having a blindfold over his eyes, he can see you just fine and charges when you get in his sight. |
| 1990 | * BoltOfDivineRetribution: One of only two bosses in the game to summon beams of light from up high. |
| 1991 | * DoppelgangerAttack: He can charge across the screen alongside five or so clones. In ''Rebirth'', it's upgraded to about a dozen. |
| 1992 | * GeniusBonus: [[invoked]] The secret calls him "A Forgotten Horseman", reflecting the fact that he's been replaced by Pestilence both in the game and in nearly every other version of the HorsemenOfTheApocalypse. Also, it was replaced because it was too similar to War. Conquest has improved versions of War's attacks. |
| 1993 | * HolyHandGrenade: His beam attack. |
| 1994 | * LightIsNotGood: He sports a white blindfold, has an attack involving beams of light, and is a Horseman of the Apocalypse. |
| 1995 | * MissingSecret: Weird variation. Conquest does not need to be specifically unlocked, [[http://imgur.com/a/AZ5GE but there is an unused picture for unlocking him.]] Subverted in ''Rebirth'', where taking ten angel room items unlocks him. |
| 1996 | * SharedLifeMeter: During Conquest's DoppelgangerAttack, hitting any of his duplicates will cause damage to the main Conquest. If his health drops to zero during this attack, all Conquests will die at the same time. |
| 1997 | * SixthRanger: An additional horseman added later. Technically, the original passage from the Book of Revelations likely referred to Conquest, not Pestilence, but the most modern usage of the horsemen ignore Conquest. |
| 1998 | * VictorGainsLosersPowers: Drops his White Pony on defeat. |

| 2008 | The Headless Horseman has a low chance to replace any of the Harbingers. He is a DualBoss between his body and his head, and he uses a combination of attacks from the original four Horsemen. |
| 2009 | ---- |
| 2010 | * AllYourPowersCombined: The head has Famine's triple shot and War's triple charge, while the body is Pestilence minus spawning enemies. Plus, you fight two bosses at the same time, which is what happens when Death loses half his health. |
| 2011 | * BodyHorror: His head appears to be missing his jaw, letting his tongue and blood drop out of his mouth. |
| 2012 | * DegradedBoss: The head alone can appear in normal rooms once you reach the Depths. The body can as well starting from Sheol/Cathedral. |
| 2013 | * DualBoss: The boss is split into: his head, that charges and shoots small bullets, and his body, which shoots large bombs and leaves trails of blood. |
| 2014 | * EarlyBirdBoss: While the Headless Horseman is manageable with a few items, he can just as easily show up in the Basement and wipe the floor with you due to being much stronger than just about any other Basement boss. |
| 2015 | * HeadlessHorseman: [[ShapedLikeItself Well, yeah.]] |
| 2016 | * ManiacTongue: Justified. While he's a boss and his tongue always sticks out, he also doesn't have a jaw. |

| 2028 | A demon that can replace any regular boss after Isaac enters a Devil Room, who drops a random item from the Devil Room pool on defeat. The Fallen fires projectiles or chases Isaac then shoots a 4-way Brimstone beam. At half health, The Fallen splits into two copies of itself which each possess the same attacks. |
| 2029 | ---- |
| 2030 | * AsteroidsMonster: After 50% of his health his gone, he splits into two versions of himself. |
| 2031 | * BullfightBoss: Does this when he isn't shooting. The charge is stopped by shooting him enough times or when he reaches you, after which he'll [[BeamSpam shoot blood in every direction.]] |
| 2032 | * DegradedBoss: In Sheol. He's later fought at full strength when the Satan fight begins. |
| 2033 | * DualBoss: A Double Trouble boss room in Womb or Utero can contain two Fallens or a Fallen with Little Horn. |
| 2034 | * EarlyBirdBoss: He can replace ''any'' boss that's not pre-set by the level. If you're really unlucky, he can appear as early as ''[[NoobCave Basement 1]],'' which in most cases is long before you can get access to any of the more powerful items. Thankfully, ''Rebirth'' toned this down and made him nearly impossible to encounter before Caves 1 (the only way is a Red Chest taking you to the Devil Room and you getting ultra unlucky). |
| 2035 | * TheDragon: To Satan. He even acts as the first stage of his master's boss fight! |
| 2036 | * FallenAngel: [[ExactlyWhatItSaysOnTheTin It's in his name, after all]]. It's especially apparent when he precedes his master, {{Satan}}. |
| 2037 | * HighPressureBlood: He shoots Brimstone lasers in all four cardinal directions simultaneously for one of his attacks. |
| 2038 | * {{Nerf}}: In ''Rebirth'', The Fallen's health scales based on the floor, making him significantly weaker on early floors. Additionally, he now only appears if you've been inside a Devil Room previously. |
