X-Men: Days of Future Past (Unmarked Spoilers)

[J Ryan]

Well remembered, I had completely forgotten that part.

Hmmm, well any explanation depends on how far you're willing to stretch SoD. (In reverse order of probability) Xavier used his powers to bully his legs into working again if only briefly; another mutant was using TK to make his legs work, or at least support him for that brief scene; an experimental treatment that restored function for only a short time before failing and causing even more damage so that he can't use it again; the director was on drugs.

Or he was actually sat in the Helicopter and for some reason decided to project a walking image into the Kid's minds.

Pretty disappointing.

And do they just hate Colossus?

[Kojiro]

Could you perhaps go into detail Havok?

[Havok]

When I have some time. I may see it again though.

Okay, I don't think this has been answered: How the fuck was Charles even alive in the war-torn future timeline? Wasn't he ripped to pieces by Phoenix in Last Stand? I heard he made a brief cameo in Wolverine with a throw-away remark about having 'gifts', but I can't recall anybody offering up an actual, even in-universe explanation for his reincarnation.

Wolverine Origins was before X-Men 1. I have no idea why Charles was able to walk in that bit, though, and still have his powers. That one's going to take some explaining, if they ever get around to it and don't do some after-the-fact Lucas-style ass-pull digital editing a wheelchair in.

In universe... he just happens to have an identical twin brother. Uh huh. That's terribly fuckin' convenient.

There's a basis for it in the comics, at least.
