I updated all 3 timelines with the new informations we got from DARK PHOENIX.
1- "Dark Phoenix" features the third alien element in the saga (D'Bari). Adamantium comes from an alien substance extrapolated from a meteor, and Apocalypse's special armour and body-swapping equipment/base is obviously alien (Celestial?).
2- In the original timeline(s), the Cosmic Force was orbitating around Earth in 1992, but the "Endeavour" shuttle wasn't there, as well as the X-Men (more specifically, Jean Grey). So presumibly, the Force ignored Earth and kept travelling across galaxies as always. D'Bari people followed it... elsewhere.
3- Hank uses a different (new) serum, because he can convert into Beast without getting "angry", as evinced before the train fight.
4- Mystique is the third X-Man to die in the final timeline, after Banshee and Havok.
5- Vuk must be a "mutant" D'Bari and not a normal D'Bari, because she managed to handle the Force and absorb it from Jean.
6- The helmet Magnet uses is the original one from "First Class", apparently.
7- DP Selene resembles LS Callisto a lot.
8- Beast is the first X-Man to join the Brotherhood of Mutants.
9- The Mutant Containment Camp must have been existing BEFORE the events of "Dark Phoenix". This means that humans STILL secretly feared mutants, despite the X-Men had become national heroes.
10- The KITCHEN where Hank confronted Charles is not the SAME where Charles met Raven for the first time, as claimed. The school has been rebuilt from scratch at the end of "Apocalypse", indeed.
11- In the movie, Raven criticized the use of identical uniforms. Surely she preferred the individual costumes at the very end of "Apocalypse".
12- Raven doesn't display any super-agility feats in either "Apocalypse" and "Dark Phoenix".
13- Beast's make-up in DP was the best out of the 5 Fox movies featuring Beast.
14- The "killing spree" of Nightcrawler is totally IN CHARACTER. First, he already had got his "sin tattoos" by the age of 18-20 (see "Apocalypse"), and this means that rage and other negative aspects are already present in him.
Besides, this version of Nightcrawler has a feral attitude, as evinced in the Danger Room at the end of "Apocalypse", where he growls like an animal.
15- Storm could have kept Apocalypse's power enhacement, after all. The impressive multiple lightning display is very powerful and never shown by any other incarnation of Storm before.
16- Storm apart, codenames are almost never mentioned.
