I'll be honest. I've never liked the Monster, not in his Marvel incarnation. I'm going to assume that you all know his story, and I lack the patience to go into detail about his Marvel adventures, so I'll simply say this about him: he helped save innocent lives in 1898, from a crewman of the ship that rescued him to a village of disfigured outcasts to various Germans. He even fights against Dracula on at least two occasions, killing the vampire at least once.
