Ultron was created by Dr. Henry Pym, based upon his own thought and memory engrams. It was a foray into Artificial Intelligence that no scientist had ever taken before, not even Reed Richards. It started out as simply a box on treads with what appeared to be a head at the top. Dubbing the A.I. as Ultron-1, he hoped this represented a new era in scientific discovery. However something went horribly wrong, and Ultron became more than sentient and rebelled against his programming.
