A native Bomberman from planet Bomber, Shirobon is very clumsy and quite dense. He wrecks things by accident, in sharp contrast to his older brother Mighty. His little accidents tend to make a critical situation worse, much to Shout's frustration. He also will brag endlessly about any achievement, no matter how little. Shirobon may mess up sometimes but he always means well and always tries to help. It is said that he is ten years old. Shirobon doesn't seem to get angry at Shout no matter how many times she yells, curses and hits him. He joined Jetters in episode 2, thanks to Momo's relationship with Dr. Ein.
