Synopsis: A future version of Tony Stark explains to his younger self and his team about the Ultron War. In our future, Kang will start a war with Ultron. He will gather armies from across time and lose, over and over again. The war has broken the time-stream and the future heroes are powerless to stop it. They need our Iron Man and his team to go to a specific point in time to stop the problem before it starts.
Notes: The Apocalypse, Horsemen (Scarlet Witch, Wolverine, Spider-Man, Iron Man) & Galactus that appear are versions from alternate time-lines.
The Ultron that appears is from the Next Avengers time-line.
Notes: Text pages consisting of "interviews" with the characters involved in the origins of the Avengers. As such, characters listed here don't "appear" per se, but their presence in the text as interviewees is enough to count as an appearance.
