Kaiser Onions are baddies that make their first appearance in Papa Louie 2: When Burgers Attack!.
Kaiser Onions are a small group of high-ranking officials within the infamous Onion Ring. They take direct orders from Sarge and oversee squads of Army Onions. Kaiser Onions have sharp, pointed helmets that counterattack any customer foolish enough to pounce on them from above. They can be spotted marching atop the wooded walls of Fort Onion.
