A feared doctor and man of science, Dr. Starline thinks he's far better than his villainous contemporaries, including Eggman. He's a smug, devious, self-serving sociopath seeking to be the fattest and most powerful slob on Mobius, he'll do anything to achieve his goals, including squashing any heroes hoping to stop him under his enormous belly or his gigantic flabby butt. He can use portals to feed and special gloves to hypnotize people to stuff themself or do his bidding.
