I quite like Skullitron, but mine was quite loose in robot mode (there is a part of the transformation that involves pulling up the center torso, and doesn't hold right). But he looks kick-ass. I really am much happier with Megatron. I had thought it just to be a straight repaint, but it's a brand new sculpted head with the 'fangs' or face horns (not sure what to call them) of Movie 5 Megatron.
