User blog comment:ADour/Official title for Marvel's The Avengers sequel announced!/@comment-1671874-20130721222300/@comment-4651179-20130721231726

Who knows, in the comics, Ultron was revealed to be Hank Pym's creation sometime after his appearance, rigth?

Anyways, they can make Ultron Tony Stark's invention (what I personally dislike, as it would make the MCU even more Iron Man-centric than before, even if I'm a big Iron Fan), after all, Tony already created an A.I..
