11 Comic Book Origins That Were Very Different In The Movies
11. Professor X - X-Men: First Class (2011)
The weird thing about X-Men: First Class and its origin stories is that, while Magneto's is kept entirely the same, Professor X has huge portions of his past changed for reasons that aren't immediately apparent.
While the fact the Xavier came from a wealthy family is still within the film, we learn that in this universe, the telepath met Mystique in his childhood, with the two bonding over their shared experiences as young mutants. This is especially interesting, as Charles would meet the blue mutant considerably later in the comic side of the franchise, and the two sharing no lifelong bond as they do in the film.
As is often the case with these types of changes, this was likely done to avoid having centuries-old characters within the film series, as where the film has Raven be a child in 1944, the comics have her as an already grown adult in 1921.
