I loved this guy. To me, one of the most awesome regular baddy bots in a Megaman stage. I always called him Cactus Joe; whether or not that's his name or not is another story. Cowboy Joe? Bandito Joe? Not a Joe? I dunno. Anyways, it's that green, gun-toting enemy from Tomahawkman's Stage in Megaman/Rockman 6 of the Classic Series.
Go ahead, make his day.
