Ultron really is one of the weirdest comic book villains. He was created by a human, decides he wants to kill all humans. Then creates a “son” who turns on him much like he did to Hank Pym. Then he creates a “wife” based off of Pym’s wife Janet Van Dyne, who also eventually turns on him. Ultron must have the worst daddy issues of any villain ever. Certainly of any robot.
