Gargantua (Edward Cobert) is a fictional character appearing in American comic book published by Marvel Comics.

Gargantua first appeared in The Defenders #126 and was created by Alan Kupperberg and J.M. DeMatteis.

Edward Cobert started out as a S.H.I.E.L.D. agent and scientist working on an experiment called Project: Lazarus (also known as the Olympus Project). The project went horribly wrong when he tested it on himself, causing Edward to be stuck in giant-size with a greatly limited intelligence. He went on a rampage until he was subdued by S.H.I.E.L.D., and was dubbed Leviathan. However, he escaped S.H.I.E.L.D. custody and battled the Defenders who managed to subdue him. He was later freed from S.H.I.E.L.D. custody by Professor Power and the Secret Empire who arranged for his release and used him as a henchman, but he was defeated by the Defenders again.

The Secret Empire freed him again when the Defenders infiltrated the Secret Empire's HQ and he helped capture the Defenders. Even so, the Defenders escaped and overthrew the Secret Empire again.

Gargantua (Marvel) has not been a contender in any CBUB matches.
