Deconstructionist

Take Whipping Boy even further. Here you work for a demolition company. You got that job because you happen to be a gigantic robot. 

Take the Wiimote and nunchuck and guide your crushing robotic hands to tear out walls and roofs and support beams with the satisfying sound of snapping timber and crumbling stone.

 

It's not just mindless smashing. You've got to take out this building without damaging the ones next to it, you've got to make it fall a certain direction or collapse in its own footprint, etc. Until you get to a level where there's an emergency and you've got to clear two blocks in two minutes, then it is just a mindless, frantic rampage of destruction. 

Seriously, you're going to see workplace violence drop through the floor once these bastards hit the shelves. I feel less murderous just talking about it.
