Ninja Bomber faces White Bomber in the first round of the B-1 Grand Prix. His special bomb is the Shuriken Bomb which acts as a smoke bomb. By throwing many of them at his opponent, he creates a confusing smoke screen. Once the smoke screen is set up, he conceals himself and throws regular bombs. He can also move quickly enough to produce after-image clones of himself, encircling his opponent.

Ninja Bomber is defeated when White Bomber throws a bomb back in his direction after he attacks. He later appears to help other Bombermen challenge the Proto-Max Units.
