Shocksqach

Shocksquatch is a white and blue Yeti/gorilla-like alien with some small metal plates over his body. With these metal plates, he can create friction and conduct electricity and release it in a form of a powerful yellow lightning beam. He briefly debuts by accident in the special crossover "Ben 10-Generator Rex: Heroes United" due to the Alpha Nanite hacking the Ultimatrix a couple times. Ben was unable to name the alien at the time.

Shocksquatch returns in Ben 10: Omniverse, with a new design like Eatle. His gray and blue fur is now yellow, he has an electric shard on the tip of his head, and the skin on his face is now gray instead of pink. He has white stripes on his arms and neck with black fur around it, with bults still around his ears and hands. He now has a green white striped belt with the Omnitrix symbol on his chest.
