Whiplash uses whips, which limits his posters to 3 things, no weapons at all, arms out with whips down(as seen) and an action shot considering you can't wrap an energy whip around yourself like a real whip. And considering no weapons would leave most people clueless as to who the hell that is, and an action shot would probably be too far away to tell it was Rourke, we are left with the incredibly common dark head-down eyes-up with weapons drawn shot that is in everything, who the OP first connected with Warrior Within.
