Monstro II is the posthumous version of Monstro. Monstro II consists of a skull with only a small patch of skin covering its right eye, which is now white.
- Hop towards the player, similar to Monstro.
- When Isaac is standing alongside Monstro II, he will shoot a brimstone laser.
- Leaps off screen and lands on Isaac's position two times in a row.
- Shoots eight blood tears after landing the first time.
- Spawns 4 suckers after landing the second time.
Champion Versions Edit
- Red: Moves and attacks much more quickly, but only spawns 2 suckers when landing.
- The strategy of always standing horizontally to Monstro II to make him shoot brimstone is not as effective. A new pattern was added so Monstro II will always make a sky leap/small hop after a brimstone attack.
- A spinal cord can be seen attached to Monstro II in his Versus image, meaning at one point Monstro had a lower body.
