X-Men Cinematic Universe - Timeline (Revised & Original)

[Regsta]

Only problem with this is that he clearly isn’t 12

I know, he doesn't look like 12, but this the way to use his birth year in Apocalypse and Origins taking place in 1979, as officially is. I know your "Shaw Theory" fix this, but my explanation is without the theory. We have a lot of movies that adult actors play teenagers, could be the case.

In Original Timeline, in early 1979, a 12 years old Scott Summers had his powers manifested in a public place, he was with his brother Alex, so people witness he was a mutant. Alex say that he should go to Xavier's school, but Scott didn't want, Alex didn't insist and send him there (like he did in Revised Timeline), Alex then have a idea, he asks his friend Hank McCoy/Beast, to do "special glasses" to his brother. Scott then get his ruby quartz glasses, made by Beast, and returns to his normal life. School was informed that he need to use the glasses, because of eyes condition. Stryker learned, through news reports, about a mutant with "laser eyes" in Ohio, it's causing interest in Stryker to use this mutant powers in Weapon XI, so he send his crew to investigate, leading then to discover the mutant identity, which was Scott Summers, eventually learn what school he was attend, they informed Stryker. In Origins, when we see Scott he was recently starting using ruby quartz glasses, he was bored/tired with Spanish class, he didn't get teacher's attention at first/she hadn't noticed he was wearing sunglasses when she meet him and class. The Spanish teacher eventually notice him with glasses, seeing he was bored of the class, then she ask him to remove the glasses, he say that he was with headache as a excuse. She was a substitute teacher, that didn't knew that he need to use glasses, Scott, who was shy, didn't say that he need and he didn't have friends to support him in that class. The teacher then put him in detention after class. Victor Creed and Stryker capture him in school.

Scott and Jean's age is very down to the wire to where you have to consider him looking older in the OG timeline and Jean looking looking younger in that same OG timeline compared to the revised one.

They are both around 16 in X-Men Apocalypse (1983) as an approximation.

And I choose to ignore Stryker's "15 years" line like I chose to ignore Joe Chill in CW Gotham Knights' "50 years" claim.
