Chimera is one of the bosses that can appear in the Corpse.


In its first phase, Chimera will slowly chase the player while using the following attacks:

  • Spawns a Sick Boom Fly and hurls it towards the player
  • Spawns multiple Small Maggots
  • Sprints towards the player, trailing creep
  • Does two consecutive jumps, spurting out tears on the first impact and creating a swirl of ground rocks on the second
  • Spits out a flurry of fast, small ipecac shots in the air
  • Spits fast shots towards the player

Once its HP is reduced to 50%, its head will pop off, acting as a separate entity from now on. The body will still slowly chase the player. The two parts will use the following attacks:

  • The body will:
    • Do a Cage-like rolling attack
    • Pick up the head, throwing it towards the player. When the head hits a wall it creates a burst of bullets
    • Go to a wall, fire a Brimstone shot away from the wall, spurting out Cage-colored tears in every direction in a Monstro's Lung-like pattern
  • The head will:
    • Do a hop and then slide towards the player trailing creep
    • Fire three parallel chains of bullets that move in a sine wave-like pattern
    • Fire five parallel chains of three bullets
    • Do a Dingle-like triple charge, trailing creep
    • Spawn Small Maggots
    • Charge towards the player trailing creep, upon missing and hitting a wall or rock, blood bullets will scatter randomly



  • The Chimera was, according to Greek mythology, a monstrous fire-breathing hybrid creature, usually depicted as a lion, with the head of a goat arising from its back, and a tail that might end with a snake's head.
  • The term Chimera is also used to describe an organism formed with multiple separate genetic codes. This phenomenon occurs when multiple fertilized eggs merge during the pregnancy or after a transplant operation when the host and giver's codes coexist.
