Synopsis: The Avengers are attacked in present-day New York City by an alternate time/universe version of Apocalypse and his Four Horsemen. Iron Man (Tony Stark) learns that Apocalypse has no idea where/when he is or why/how he is there. Apocalypse vanishes into the time stream, but now Tony can follow his trail trough the damaged timestream. The team splits up, half working on building a time machine, and half fighting the time-displaced threats in present-day New York.
Notes: The Apocalypse & Horsemen (Scarlet Witch, Wolverine, Spider-Man, Iron Man) that appear are versions from an alternate future.
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.
