The Moth is one of Mermaid Man's arch nemeses whom he has been tracking down for 57 years. He appears in the episodes "Night Light," "Mermaid Man Begins," "Squid Noir," and "Appointment TV," and is voiced by Mark Hamill.


He is muscular, has a light brown body, a pale-green head, dark orange antennae, pale-gren hands, giant light yellow wings, and red eyes. He wears a pale-green speedo.

The Moth is an underwater, small, miniature insect who wears a typical superhero suit but is a villainous bug.

Role in episode

"Night Light"

He is attracted to all of the light given off at SpongeBob's house, especially the lighthouse. SpongeBob traps him inside said lighthouse, but he escapes by carrying it inside the cage, and he flies away.

"Mermaid Man Begins"

He appears as one of the Mermaid Man and Barnacle Boy action figures owned by SpongeBob.

"Squid Noir"

He once again appears as an action figure on a display inside of Near Mint Comic Books.

"Appointment TV"

He, along with Man Ray, the Sinister Slug, and the Dirty Bubble, are seen ganging up on Mermaid Man on the poster for the lost episode "The Case of the Curious Cliffhanger."


  • Due to his voice being provided by Mark Hamill, he sounds a bit like Hamill's other famous role, The Joker from Batman: The Animated Series.
  • He resembles the famed monster, Mothman, with wings and red eyes.
  • The Moth looks similar to Superman (even though he is a bad guy whereas Superman is a good guy) and the Owlman.
  • It's unknown how he's able to breathe underwater despite not having a diving suit.
