Captain Magma is a superhero who is only seen in the episode: Mermaid Man and Barnacle Boy V. He is part of The International Justice League of Super Acquaintances. He is probably retired and was replaced by Squidward. 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
