Onslaught will appear during the shows run.
Hey, Age Of Apocalypse made an appearance, so, why not?- Maybe because Xavier's in a coma for the next 20 years? So even if Onsluaght does pop up somewhere, it'd have to be in the Age Of Apocalypse...and an epic battle would ensue.
- Perhaps he'd come to life because of the coma? While Xavier's unconscious, sooner or later, Onslaught will take control, hypothetically.
Gambit will join the team in Season 2.
- Because the fans will want it.
Emma Frost is not dead.
- Death Is Cheap in comics, even many of their adaptations.
- This was actually confirmed. The producers said, had the show continued, Emma would've come back.
Rogue is Logan and Mystique's daughter.
Back when he knew he was James Howlett, he and Raven got along much better than he currently knows. Sabretooth got jealous and ratted them out to Thorton and Cornelius, but Raven was already pregnant. She went into hiding to protect little Anna, and trusted her good friend Irene (Destiny) to raise her while she worked for Magneto to make the world a better place for mutants, including her and James'/Logan's daughter.- Logan fought in just about every major war, wars that Rogue never read about in history class.
- Alternately, Nightcrawler is Logan and Mystique's son, if Mystique is still his mother.
The Legacy Virus will be a future plot line, perhaps subplot.
- It got a shout out with the 'legacy cure'. Perhaps the cure will be taken by a group of terrorists and corrupted into the virus, meant to kill mutants rather then cure them?
This is the same universe Nocturne from Exiles originated from.
- Wanda and Nightcrawler in love? Check. Wolverine leader of the X-Men? Check. Cyclops Darker and Edgier? Check. The ground work is there. Hopefully she will at least appear in one of Xavier's futures.
Stryfe would have appearred in Season 2.
- Sinister had Scott's and Jean's DNA, and I doubt he'd be eager to make Cable or X-Man.
- He's been eager to make them before, he just didn't expect the results he got.
- Considering the future seen in the finale was similar to Age of Apocalypse, it would probably have been Nate Grey (X-Man) who would have appeared.
Future!Xavier is suffering from dementia.
Possibly caused by or compounded by the brain damage from his long coma. That's why he picked loner Wolverine as leader instead of groomed-for-leadership-since-puberty Cyclops.- Yeah, because a guy who's obviously depressed and maybe even unbalanced from loosing his girlfriend is the perfect choice over a former CIA agent, who has over 100 years of combat experience, in leading a black ops-style team of superhumans.
- Who knows if that's even true, given how messed up his memories are at this point.
- And how else does one explain Storm and Beast not being considered as replacement leaders? Storm's led the team in the past in the comics when Cyclops wasn't around and Beast is considerably more responsible than Wolverine.
The whole series is a Danger Room scenario to test whether Wolverine is any good at leadership.
- Judging by the show's cancellation, he failed.
- Not really he DID succeeded in stopping the Sentinel-Takeover-The-World Timeline but then Xavier probably decided to give him new test but Wolverine probably got tired of it and decided to leave
Cyclops would have finally done something heroic on his own with no help from anyone
- Seeing as how he ended up working for the bad guys in the future, probably not.
Cyclops would finally figure out that Jean Grey was the wrong girlfriend for him, break up with her and go hook up with the resurrected Emma Frost, who obviously is right or at least a better girlfriend for him than Jean
- Emma couldn't possibly treat him worse than Jean and Jean was probably getting tired of pretending to love Cycke anyway.
The other X-Men besides Nightcrawler would finally get some actual character development.
- Given the show's formula, probably not.
- Call it karma for Nightcrawler getting shafted in too many adaptations.
Colossus and Kitty would finally get together
- Lord knows they'd make more sense than Cyclops and Jean.
Jean and Xavier were secretly mind raping Cyclops for years prior to the events in the show.
- Seriously, Xavier just doesn't give a damn about Cyclops and Jean at best treats Cycke like an abused dog she found in an animal shelter that she has to keep on a leash so that he doesn't go around biting people. How else can their cold treatment of him be explained other than Mind Rape?
Cyclops' attitude is partially due to brain damage
His inability to control his eye beams and thus need special lenses is in most continuities is due to brain damage. It is possible that same brain damage also impacted part of the brain that deals with emotions and and like. Hence his behaviour.
