that kinda messes up any plans to use Ultron in Avengers in future
Yeah, I keep going back to MA Avengers for ideas, but it's good stuff.
I figure, just borrow the plot for MA Avengers #1 for Avengers 2: another section of the government/military builts the Ultron program to replace the Avengers (inter-department rivalry, natch), which immediately tries to take over the world, so the Avengers have to stop it.
