YMMV: Avengers Forever
- Author's Saving Throw: This story to what happened in The Crossing. It's revealed that Immortus had only manipulated Iron Man since Operation Galactic Storm to the Crossing and not from day one and that the Mantis who seemed to have made a Face-Heel Turn was really a Space Phantom.
- Harsher in Hindsight: Immortus's effords to prevent the existence of the sons of the Scarlet Witch, which would lead to a reality warper rocking the cosmos, was based in storylines at the West Coast Avengers, where she was acknowledged as the "Nexus Being". But reading it nowadays, it gets a whole new significance after Avengers Disassembled and House of M.
- Heartwarming in Hindsight: Songbird and Captain Marvel came from a future where both of them were Avengers, and more than that, they were lovers. So far, they never became Avengers, but Captain Marvel joined the Thunderbolts instead and had a lot of Unresolved Sexual Tension with Songbird. As Immortus would say, destiny does not like to be thwarted.
- The Woobie: Captain America. This particular Captain America was plucked from time right after the ending of the saga of the "Secret Empire", where Captain America followed the leader of a terrorist organization to the White House, where he unmasked himself and revealed to be a top-level US officer, planning a coup d'état, and who committed suicide before being captured. This story, written in 1970s by Steve Englehart, left him completely demoralized, and resigned as Captain America shortly afterwards (the Captain America of Avengers Forever had not decided this yet). Well... Kurt Busiek thinks that Englehart's Captain America had not suffered enough. He made him leave Kang's soldiers to their deaths, he sent him to a post-apocalyptic future, he makes him realize that the human race is the most dangerous species of the cosmos, he has to hear things that would happen in his future (such as governments ordering to dismantle the Vision, Iron Man committing murders and framing Hawkeye, etc), a Bad Future with the Avengers turned into a conquering army, a chance to erase Hitler from existence, and so on, and so on... let's just say that, in any other story, if some alien ships begin to fire to the Avengers, he would raise his shield and head to the battle crying out loud "AVENGERS, ASSEMBLE!". Here, he hides in some ruins, unsure of what to do.
