Invader Krunk is an Irken Invader assigned to an unknown planet. He is squat and somewhat pudgy, with a thick neck and a very prominent lower jaw. These features imply that he has a case of underbite, which seems to be very common in Irkens. Presumably due to a coloring error, Krunk is one of the few Invaders to have no spots on his PAK, and is missing stripes on his uniform.
