Howard the Duck is a fictional character appearing in American comic books published by Marvel Comics. The character was created by writer Steve Gerber, based very loosely on his college friend Howard Tockman, and artist Val Mayerik. Howard the Duck first appeared in Adventure into Fear #19 and several subsequent series have chronicled the misadventures of the ill-tempered anthropomorphic animal trapped on a human-dominated Earth. Echoing this, the most common tagline of his comics reads 'Trapped In a World He Never Made!'.

William Timothy Mantlo is an American comic book writer, primarily at Marvel Comics.

An attorney who worked as a public defender, Mantlo was the victim of a hit-and-run accident in 1992 and has been in institutional care ever since.
