Monstro II is a boss found in The Depths and the Dank Depths, and 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.

Behavior[edit | edit source]

  • Hops towards the player, similar to Monstro.
  • When Isaac is standing to the left or right side of Monstro II, he will shoot a horizontal Brimstone 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 | edit source]

  • Red: Moves and attacks much more quickly, but only spawns 2 Suckers when landing.

Gallery[edit | edit source]

Notes[edit | edit source]

  • Monstro II can often be seen with 2 Attack Flies to its left and right sides.

Trivia[edit | edit source]

  • 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. The spine can also be seen when he fires a Brimstone Brimstone

    laser.
  • Monstro II is missing a tooth, most likely a reference to Monstro's Tooth.
  • In the Versus image Monstro II can be seen to have three bottom teeth, yet when you fight him, they do not appear.
  • Unlike other posthumus bosses, Monstro II is found two chapters away from his base boss, Monstro.
    • This also applies to Teratoma, who is found three chapters away from Fistula.
  • In the original Binding of Isaac, Monstro II was the only posthumous boss ingame, prior to the Wrath of the Lamb DLC.
