The Moth is muscular, has a light brown body, a green head, speedo, has hands, and has red eyes. He also has giant wings.
The Moth is an underwater, small, miniature insect that wears a typical superhero suit but unfortunately he is a villainous bug. He was attracted to all the light given off at SpongeBob's house, especially the lighthouse. SpongeBob trapped him inside the lighthouse, but he escaped by carrying it inside the cage. He flew away, and has not appeared since. He later appears as an action figure in "Mermaid Man Begins."
He is voiced by Mark Hamill (actor of Luke Skywalker from Star Wars and the voice of the Joker in most of the Batman animated series and voices Skips in Regular Show).
He resembles the Famed monster, Mothman, with wings and red eyes.
He is a parody of Batman's villain "The Killer Moth."
