Also a comic book character by Marvel Comics. Gargoyle was a man over 70 who was tricked by a devil into switching bodies with an animated evil gargoyle. He attempted to atone for this by becoming a hero and fighting with The Defenders.
He joined the team (I believe) in issue 97, and remained with them as the only constant member until the end of the comic (or there abouts - in one of the team's final battles his body was carbonized and his soul freed to wander the universe - I will consult the specifics as soon as I pull out the collection).
He had a excellent 4 issue limited series devoted to himself, and I hear he came back briefly after the Defenders were dismantled - but I heard that story wasn't any good and never pursued reading it.
If you can't tell, he was always my favorite character. :)
