Buzzshock is similar to a battery. He is black with green eyes. He has a white large lighting like line down the place where his neck starts to where his legs start on his front and back. He has a positive and negative symbol on his back. He wears the Omnitrix/Ultimatrix symbol on his chest.
He appeared in Ben 10,000 being used by Ben 10,000 himself, and in Ken 10 being used by Ken.
In Ultimate Alien, Buzzshock's Ultimatrix symbol is on his chest and is green. He now has a battery tip over the hole on his head.
Fire takes away his power, as well as getting trapped in something made of a nonconductive material without any electricity to absorb. Also water seems to make him short-circuit, just like any machine.
