Monsters refers to the many antagonistic creatures the player will encounter throughout the game. Antibirth adds over 80 new monsters, many of which are found in the new Chapters.
Monster List
| Monster | Description |
|---|---|
| Fart Maw | Flies around and emits a fart when Isaac gets close, when hit and upon death. |
| Soy Creep | Crawls along walls to try to line up with Isaac and rapidly fires white tears in a straight line. |
| Blood Trite | When it jumps it fires a red tear towards Isaac and occasionally bursts multiple red tears while not jumping. |
| Leech | They constantly move towards Isaac. They can go over holes but not any other obstacle. |
| Water Spider | They float above water and only do little hops of movement towards Isaac. They can also go over holes and no other obstacles. |
| Water Gaper | Spawns in the room after the clearing of the other enemies, |
| Leech Gaper | Same as the Water Gaper but spawns a leech on death. |
| Spit Gaper | When it gets close enough to Isaac it releases a wave of tears towards the player and turns into a normal Water Gaper. |
| Water Gaper Reflection | You can only see the enemy's reflection in the water and not the enemy itself.
When a lightning strikes you can see the full enemy for a split second. |
| Water Fatty | Occasionally shoots a single tear at Isaac.
When Isaac gets too close this enemy farts and bursts tears in random directions. On death he creates a temporary rain of tears where he died. |
| Water Mulligan | Runs away from Isaac and spawns leeches instead of flies. Unlike the normal Mulligan, he drops nothing upon death. |
| Fire Fly | This enemy flies in a ring around Isaac and occasionally shoots orange tears at the player. |
| Strenghty Ghost | This enemy has the ability to pick up obstacles and throw them at Isaac just like the Mom's Bracelet item. |
| Stone Squirt | This enemy charges at Isaac and it doesn't stop until they hit an obstacle or one of the walls of the room.
When it hits any hard surface, it fires waves of stone tears at Isaac and rocks also start falling from the ceiling of the room from the impact. After it gets hit 3 times it transforms into a dip. (thus dying) |
| Stone Bomber | These enemies shoot miniature bombs at you. |
| Bomb Fly | When killed, the bomb fly turns into a mini bomb. |
| Balloon Mulligan | This enemy runs away from you, but when you get too close its head gets inflated and then explodes when it gets too close to Isaac or it dies.
When their head explodes, it also bursts into red tears. When they die, they fire 4 red tears in all directions. |
| White bat spawner | White bats are offscreen at the top of the room. When Isaac gets too close they wake up and chase after the player. |
| Mole rat | This enemy only moves when it's under the floor and it leave a trace of dirt behind them indicating their location.
When the mole is close enough to Isaac it pops out and shoot 3 red tears at the player and then goes back under the ground. |
| Half Headed Gaper | This enemy shoots 5 red tears in different directions and follows Isaac.
When it dies it turns in a Gusher. |
| Rock Host | This enemy acts like a normal Host but it fires lines of rocks from under the ground at Isaac. |
| Stone Spitter | This enemy follows and shoots rock tears at Isaac.
There's a random chance that when the rock tears get destroyed they spawn a rock spider or a lava spider. |
| Hoppy Brain | This enemy jumps around the room and leaves a trace of blood behind which hurts Isaac. |
| Flaming Gaper | This enemy shoots lava rocks towards Isaac. |
| Lava Fly | This enemy flies towards Isaac and on death it drops a tear which when falls on the ground spawns 4 lines of flaming rocks that come out of the ground. |
| Slicer | This enemy has a wide melee attack. It charges towards Isaac similarly to a Bony. |
Warning!
These aren't the official names of these enemies, they're just nicknames I found fitting.
The community should change the name of an enemy to something more appropriate if they think that it would be an improvement.
The list is not yet complete. It doesn't contain all enemies yet. I would love it if people could help with images for these enemies, as cropping out each and every single one enemy is time consuming. (~~~)
