Rapid Run is proud of being the toughest member of
the Bullet Train team. He is always ready for a fight and loves
a good brawl. He fires his grenade launcher to confuse the enemy
with a blinding wall of smoke, so that his fellow Autobots can send
in the heavy weapons. His aim is always accurate, so he never has
to fire more than once.
Later versions of Rapid Run came with
painted blue windows.
