Even in the show most of those teens are still training maybe not as much as the older ones.But, like, aren't most X-men just teenagers? I mean, yeah, Storm and Cyclops and Wolverine have been training for ages. But like, the school is named "Xavier's School for Gifted Youngsters." Doesn't that preclude that some of the X-men aren't fighting fit because, you know, they were just some kid prior to getting mutant powers?
(Not a rhetorical question. I am legitimately asking.)
