A new boss would be awesome

Ok, now think about this mojang. We have the wither and the enderdragon, but what about another boss? I was thinking of an golem that slams the ground and lifts blocks up. Then it has a cool down and that is when the player attacks. Also, whenever the cooldown happens, I think his arms should drop and the player could run onto his arms and hit his head for extra damage. I think it would be very cool with this. If not, could you bring back the copper golem, I mean who could say no to him? I know I can’t.
