The Inedible Hunk appeared in the first Captain Underpants comic made by George Beard and Harold Hutchins. He was the villain of the comic. He started eating everything around him. When Captain Underpants arrived, he distracted it and they went into the toilet. He threw some plungers at it but it ate them, then once again he made him run around. When the Inedible Hunk got tired, Captain Underpants offered him a drink from the Toilet Bowl, when he started drinking, Captain Underpants flushed him.
He had a slime-like body and he would get bigger as he started to eat things.
- His name is a parody of The Incredible Hulk from the Marvel Comics.
