On a road trip with his cousin Gwen and his Grandpa Max, Ben finds an alien watch, the Omnitrix, which allows him to transform into 10 different aliens. Once transformed, Ben takes on the alien’s appearance and powers, while always remaining a ten year old boy. The result…the ultimate kid superhero! Cannonbolt can curl himself up into an unstoppable, nearly invulnerable sphere. Like a life-sized pinball, he can ricochet off surfaces and knock down his enemies at super speeds! He has no trouble getting moving, but sometimes he has trouble stopping!
