Mr. Sinister's 2028 X-Men Plot May Already Be Hiding in Spider-Man: Brand New Day

Spider-Man: Brand New Day may have already clued us into how Mr. Sinister gets used in Jake Schreier's X-Men movie, set for 2028. The connection comes down to a government program, a mysterious tank, and a scientist who might not be who he says he is.

Brand New Day already sets up playing God with mutant genetics

Brand New Day introduces the idea of playing God with genetic science through the DODC, which is shown experimenting with mutant genetics. That premise alone opens the door to a much bigger idea: what if the DODC is working with a scientist they do not realize has his own far more sinister agenda?

That scientist could be Adam Driver's Nathaniel Milbury, otherwise known as Mr. Sinister. Sinister is obsessed with mutant genetics, and the idea is that the DODC could be working with him without realizing what he is actually planning.

Sinister could be using the DODC to replicate Jean Grey's powers

The theory is that Sinister could be using the DODC's technology to replicate Jean Grey's telepathic abilities in another mutant, and that this could have been his whole experiment from the start.

But for that to even be possible, some other scientist already working at the DODC would have had to have other mutant test subjects on hand, subjects they had already spent decades researching in order to identify their genetic classification.

Frank Castle's discovery of a tank with a Chitauri head is a clue

Frank Castle saw a tank inside the DODC headquarters containing a stewing Chitauri head, and that detail shows there is some freak working at the DODC who is very interested in biological samples.

The Goblin Queen storyline is probably too early to pay off yet

Jean Grey's prior Goblin Queen storyline, seen in X-Men '97 season 1, would be a bit too early to explore in this movie.

Nathaniel's cover story: helping the government while secretly hunting mutants

The way I see this playing out is that Nathaniel is going to present himself to the government as a scientist trying to help identify and contain mutants, only for it to come out that he is actually hunting them for his own experiments.

Is Brand New Day quietly building the foundation for Mr. Sinister's real agenda before his own movie even starts?
