Frog-Man is a comedic superhero appearing in American comic books published by Marvel Comics. Created by writer J. M. DeMatteis and artist Kerry Gammill, the character's costume is actually borrowed from a previously existing villain named Leap-Frog created in 1965 by writer Stan Lee and artist Gene Colan. Frog-Man was first introduced in the comic book series Marvel Team-Up in issue #121, published in June, 1982. The characters Eugene Patilio and Leap-Frog are both unrelated to the original Marvel villain called Frog-Man.
