Shocksquatch has the appearance of a thick, muscular Sasquatch-like (Bigfoot) alien. He has white, gray, and blue fur, along with a redish-pink face, and pointed eyebrows. He also has green eyes with black pupils. He has metallic grey circular bolts on the back of his hands and on his lower jaw. He wears the Ultimatrix symbol on his chest.
In Omniverse, he appears slimmer than usual and he now has yellow and black fur, along with grey fingers and toes. He now has 4 fingers instead of five. He also now has two bolts on the side of his wrist instead of the back of his hands. He has green eyes with black pupils and yellow horns. He also has a green belt where the Omnitrix symbol is located.
In Dimension 23, his fur is now yellow and blue. His eyes are blue and his belt is blue.
Much like Brainstorm, Shocksquatch has the power to release strong, yellow electrical charges from his body and they are able to be emitted from the mouth. He also possesses super strength, able to take on Four Arms.
