Well, that's one way to deal with Ultron-12... I love Pym's horrified reaction on the ground.
So, Ultron-12 manages to put his head back on(the wrong way!)and with the help of Wonder Man and Pym, Ultron-12 manages to destroy Ultron-11, but not without a heavy toll.
I think this may qualify for the most dramatic robot death I have EVER read!
