Gravattack

Gravattack is an alien who is confirmed to appear in Ben 10: Omniverse. His powers may have to do with gravity, the names Graviton (intended name) and Gravattack (actual name) suggest that as they both contain the word gravity. He is a bulky rock armoured future human species with a giant mouth. His foot is gray with 2 toes, and has a red molten-rock-heart on his chest. He also wears black pants with blue stripes and a blue belt with white stripes. He wears the Omnitrix that is up-sized on the his back like a large back-pack. It is confirmed that he and a blue villain were placed at the wrong packages like Feedback and the new appearance of Ben Tennyson. His name was originally intended to be Graviton, but they realized that was the name of Marvel's villain who fights the Avengers.
