Hamburger Baby is a superhero whose costume is made of hamburger ingredients like cheese and lettuce. He has the head of a baby but the intelligence of an adult. He uses his powers of meat, bread, and onion vision to create food to feed hungry children. However, he has weaknesses like running out of energy if he doesn't eat. His enemy is Hotdog Baby, who gained hotdog powers from Hitler's grandmother and uses them to steal food from children. The two heroes represent different eating disorders and intentions, with Hamburger Baby helping kids through his binge eating, while Hotdog Baby harms them despite his bulimia.
