His name is Flicker (off state)
Struck by lighting as a teenager turned his body into a bright light source and also transparent so you could see his skeletal system. While in his off state when no light source is coming from his body his body is fully transparent and you can see his bones clear as day. When in on State he can emit a bright light from his body. He can give a lethal electrical punch, he wears special gloves so he doesn’t effect everyone.
