The Moth is muscular, has a light brown body, a pale green head, wears a pale green speedo, and has pale green hands, and has red eyes. He also has giant light yellow wings.
The Moth is an underwater, small, miniature insect that wears a typical superhero suit but unfortunately, he is a villainous bug.
He first appears in the episode "Night Light" and he is attracted to all the light given off at SpongeBob's house, especially the lighthouse. SpongeBob traps him inside the lighthouse, but he escapes by carrying it inside the cage. He flies away. 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."
