What's worse - a chainsaw-wielding Ganado with a burlap sack over his head or the 7-foot Ganado wielding a double-bladed chainsaw?
Either way, this mofo is one of the more infamous members of the Ganados, since he will come at you the fastest way possible to kill you. Thank God for the Handcannon, I. Rocket Launcher and the Typewriter.
