Way Big

Way big
Way Big (voiced by Fred Tatasciore) is an enormous alien, nearly 100 feet tall, and by far the biggest alien in Ben's arsenal.[24] His species and home planet are unknown, but his appearance is somewhat reminiscent of tokusatsu super heroes, particularly those of the Ultra Series. Way Big's size grants him extraordinary strength and invulnerability to most attacks; however, in proportion to his size, Way Big does not seem to be any more durable than normal, as Vilgax is able to cause him pain by digging in with his sharp claws.

Way Big first appears in Ben 10: Secret of the Omnitrix, when Azmuth activates it on the Omnitrix so Ben can fight Vilgax and his forces.
