Yes, she's gone in the field with them, joined Excalibur at some point, was one of their medics.
Humans have been on the team before.
Don't be naive.
You don't need a movie to tell you they were X-Men for them to be X-Men. If you do, you're not that smart.
I think you guys are missing the point here. The group of mutants in first class were not fighting as Official X-men. A Beta stage perhaps, but NOT OFFICIALLY x-men. The name did not even exist or had been thought of so they couldn't have been "x-men" until the very end or whenever the kids thought of the name officially later in the timeline. Just because the movie is called XMEN first class, doesn't mean they are x-men in the movie. X-men Origins: Wolverine had the name X-men in it. Where were the X-men? There were mutants who would BECOME X-men... Just like the first class movie. The movie was a setup, an origin, a beginning for those character, who would become X-men.
Whatever was left of the band of mutants on that island fighting for Xaviers said became X-men. So basically Havok and Beast. Before that it was a mutant free for all, some bad, some good.
I understand what psylockolussus is trying to say. It takes a little work to understand, because its very hard to explain properly. Just because they were wearing the yellow and blue protective outfits doesn't mean they were officially x-men.
If the students came up with the name, and it was adapted by the students
(presumably Cyclops, Storm and Jean and others unknown) Then in no was was the band of mutants in first class the X-men, since there were no students and no school until the very end of FC.
Also Keep in mind the First Class was in name only. Of COURSE the movie was going to be named X-men, lol, what else would they call it? it DOES lead to the events of the X-men Creation. It really doesn't make sense in the first place, since the school hadn't been founded yet. Its really all a set up for the final scenes. The mutants involved in the movie will become the
literal first class, but it wasn't filmed. Singer just thought it was a cool name to call the movie and he stuck with it, Even if there was no official "class" as of yet. Its just a loose term to describe the first act, the initial events, the first players in the big picture, while incorporating what would become a "class" learning dynamic at the school,for future mutants, and future X-men.
Some of the first "x-men" were still Jean and Cyclops, but the first band of mutants were Havok, Beast, ERIC, Charles, etc, that helped the cause and the founding of the X-Men name, and not officially X-men in the FC climax. Like i said its hard to explain, you kinda either get the logic, or don't i guess. In the end you can chalk them up to bing X-men if you want because some of them do become officially X-men and the others affiliated with them, but with the other movies in the fold, it makes more sense that the X-Men name be adopted after the FC movie.
Cyclops sure did!

Such is the life of nerds haha.
