This article is about the boss. For the enemy, see Ministro. For the item, see Lil Monstro.

Monstro is one of the bosses that can appear in The Basement and the Burning Basement. He is amongst the most common to fight, particularly because he can appear on later floors as an enemy.

Behavior

• Hops towards the player.
• Coughs up a large amount of disorganized tears. The larger tears do one heart of damage while the short ranged small ones do 1/2 heart.
  
• Jumps off-screen, aiming to land on top of the player.
  • Fires another set of disorganized tears after landing.

Notes

• Monstro can't hop over Obstacles.
• When Monstro jumps off-screen, he is cured of all status effects.
• If Isaac is somewhere that Monstro cannot reach, Monstro will jump in place.
• Monstro can rarely spawn in a room with two Blood Donation Machines.

Champion Versions

• Red: Two smaller Monstros, each with 45% of Monstro's normal health, replace the normal Monstro.
• Dark Grey: Slightly larger and has 25% more health. Uses tear volleys much more often and is unable to jump off-screen.
