Biff Wellington
Biff is a rich billionaire and has a big adventure spirit, but he chose the wrong path when he believed in the lies of Mr. Mysterio and chose to "become" the pirate Captain Skunkbeard as he was caught by the Mystery Inc. He is tall, handsome (for an older man) and has a brown hair and beard, since he's a big adventurer he may be a possible hunk too, but that's yet to be confirmed!
