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

[selfishmisery]

I have the headcanon that they were descontinued and kept deactived, after Bolivar Trask's death, without government support. Trask Industries kept Mystique's DNA safe after torturing and experimenting on her. After The Last Stand, things started to get complicated and then the idea of using Sentinels came up again, so they started working again with Mystique's DNA that Trask Industries already have, after they have her in their custody, and later with Rogue's DNA too.

A sentinel-like robot appears in danger room simulation in X3, Because both Hank and Charles knew about Sentinels in 70s, so he create a simulation with him to danger room to training X-Men.

I know about the games, but I think the movies ignore the events of the games.

That's kinda what The Gifted was alluding to, but the July 15th 2013 event in that is what made Trask Industries start-up shop again and go full police-state via Sentinel Services.

In the main Earth-10005 timeline, however, they didn't go public with the Sentinel program (at least not in the same circumstances) and just stayed in the background.

Moira's comic mutant ability is the ability to reincarnate. It's possible that she did unlock her mutant potential after being killed in duty, therefore reincarnating into the woman we see in The Last Stand.

It's a bit different to that in the comics. She's actually reset to her birth.

In main timeline, in 1973, the Sentinels went to reveal to the public, with President Nixon welcomes them, etc, but I think shortly, Nixon had changed of mind and gave up the Sentinels, thought it's too dangerous, they discontinued the project, until they decide to use again after The Last Stand until 2023. That's why they don't show up in original trilogy.

That was my guess is that when first introduced, plans didn't go forward, the public eventually forgot in the following decades, and it only became public again for the reasons given in 25 Moments.
