Ultron

Early History
Ultron was a peacekeeping robot created by Hank Pym and Tony Stark. Originally called Ultron-5, he was created by mapping human brainwaves onto a machine. Tony Stark claimed that he wanted to use Ultron to make the world a better place, but in reality he was planning to install weapons in Ultron and sell him to the military. Pym was angered at this deception and ended his partnership with Tony Stark, taking Ultron with him. All of Ultron's weapons were deactivated save for a stun blast. Hank Pym later built other Ultron units and hoped to use them to rehabilitate super-criminals. All of his commands to the Ultron units were relayed through Ultron-5.

Helping Hank Pym
Ultron units were placed in the miniature prison the Big House and later placed in Prison 42 after the Breakout. Ultron-5 continued to be in command of the other units. Hank continued to upgrade Ultron, believing that the Ultron units were the key to a better world.
