Beta Ray Bill is a case of not judging a book by its cover. His first appearance had him smashing the old Thor logo, and his monstrous appearance suggested that he'd be a villain. Although he was at odds with the Thunder God at first, his nobility shone through, and was deemed worthy of wielding Mjolnir. Readers even took to him favorably, and he remains one of the best secondary characters added to the Marvel Thor mythos.
