* CrackPairing: 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; however [[spoiler: when Scott, who was an agent of Mr. Sinister, makes a HeelFaceTurn in part because of meeting Jean after she was captured by Sinister, the two end up back together.]]
* CompleteMonster: Apocalypse himself, having destroyed most of Asia and Russia and committed mass genocide in North America. The point of the cross-over is what Apocalypse would be able to do unchecked by Xavier's X-Men.
* EnsembleDarkhorse: Blink, though it still took her five years to cheat death and get a book.
* {{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. HilarityEnsues.
* TheWoobie: X-Man, aka Nate Grey.
