— Captain Magma, "Mermaid Man and Barnacle Boy V"
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 (I.J.L.S.A.) He was replaced by Squidward Tentacles.
He has the ability to shoot lava from his head. His costume is a red jumpsuit and a volcano hat that spurts out lava. In "The Bad Guy Club for Villains," there is another superhero who is 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. His magma is triggered by the code word, "Krakatoa!"
- If he gets hit by water, he disintegrates into ash, as evidenced when Mermaid Man, who mistook him for The Quickster, hit him with a water ball.
