- Crack Pairing: Quicksilver & Storm, Gambit & Lila Cheney, Boliver Trask & Moira MacTaggart, Exodus & Dazzler... they really go all over the place with this. However, the more official ships are acknowledged, even if they go a bit differently in this universe. For example, Jean ends up with Wolverine, since Cyclops was never an X-Man and they never met until after the cross-over begins.
- Complete Monster: Apocalypse and Dark Beast. See X-Men.
- Ensemble Dark Horse: Blink, though it still took her five years to cheat death and get a book.
- Sabretooth seems to fall into this as he was put into the main cast of the Exiles and has appeared in pretty much every story which involved Age of Apocalypse verse.
- Local version of Sunfire is also often preferred over the main one due to his cool design. They even turned him into a Horseman of Apocalypse in the main universe to make him look more like this version.
- Older Than They Think: The comic book event was actually inspired by the X-Men episode "One Man's Worth", not the other way round. The fact that animation has a much longer development time means that the comic event was published before its inspiration aired. (Incidentally, it also explains why the episode has both the AoA Morph and the animated Morph. The comic creators took designs from concept art for the episode, so the character who appeared in the comics as Morph was apparently designed as a separate character. Which makes sense, considering that AoA!Morph's powers are only marginally similar to the original's.)
- Squick: Lots of examples.
- One example stands out above all others. The Generation Next team member Vincent has the power to turn into a liquid or a gas (and maybe other things, the exact nature of his power is never explained). At one point, the GN kids are infiltrating a concentration camp. Husk gets inside by posing as a human prostitute hired by one of the camp bosses. She carries Vincent, in his liquid state, with her in a flask. After the camp boss blows her cover, he decides he wants a drink before he kills Husk, and drains the flask containing Vincent. Hilarity Ensues.
- The Woobie: X-Man, aka Nate Grey.
- Unintentionally Unsympathetic: X-Men in the 2005 mini-series. Husks betrayal was a despicable act especially after she took a child as a hostage and tried to kill her former friends. But being left behind, witnessing all of her close friends die, including the man she loved, and being tortured for a long time in a Crapsack World makes her Jerkass Woobie after all. So, maybe burning her sister alive and crushing her brothers to death in front of her, getting a "Reason You Suck" Speech from Rogue and being Impaled with Extreme Prejudice by Kirika was a bit too harsh?
YMMV / Age of Apocalypse
