Electrician is my favorite hero and I'm sad to see that he does not yet have an alternate avatar. I think I finally came up with a decent one.
Electric Mouse! (a la pikachu).
His abilities wouldn't change much. He might have a tail made of electricity that he static grips with.
More amusingly, it'd be awesome if , when activating Electric Shield, the mouse began walking as if it were inside a hamster ball.
