Captain Magma is a superhero who first appears in the episode "Mermaid Man and Barnacle Boy V." He is part of The International Justice League of Super Acquaintances. He was replaced by Squidward Tentacles.


He has the ability to shoot lava from his head. His costume seemingly is a red jumpsuit and a volcano hat which spurts out lava. In "The Bad Guy Club for Villains," there's another superhero that's possibly the same person as Captain Magma, but is called "Professor Magma" and does not speak clearly, as he only makes gargle sounds.


  • Magma Spout; Lava will come out of his head if angered. Magma is triggered by the code word, "Krakatoa!!!"


  • If he gets hit by water he disintegrates into ash (He gets mistaken for the Quickster by Mermaid Man)


  • "No...No, I'm not the Quickster, I'm Captain (in ashes)."
  • "Krakatoa!" (catchphrase).


  • Captain Magma is a parody of the Fantastic 4s Human Torch, DC's Firestorm, and Marvel's Pyro.
  • In "The Bad Guy Club for Villains," there is another superhero named Professor Magma who's possibly the same person as Captain Magma.
  • When Captain Magma attacks, he says Krakatoa, which was the name of an Indonesian volcano in real life.
