He also helped Wasp to escape from the Microverse after the Avengers/X-Men conflict. Giant-Man also helped Matt Murdock and his friend Foggy Nelson in many moments and fought his enemy Ultron during the Rage of Ultron event.

He died during the final battle. He returned and encountered the Uncanny Avengers, joining the team as Ultron. However, the group didn't trusted him and called the Wasp for some help. Then, Giant-Man becomes the Ultron and fights the Unity Division, destroying the Hulkbuster. The Vision helped the team to kill his father, but Ultron is later revealed to be still alive.
