Charles was a known crybaby back in the early 90s.
Guy would train his ass off, get in shape looking extremely well when standing alone and then... boom! When compared to others he disappeared.
He disliked Dorian's physique big time too. He made it a point to always go out there and complain about Yates in the magazines, TV interviews, et cetera.
He seemed to like judging more than bodybuilding. Too bad he chose the wrong profession.
