Spider-Man: Brand New Day Rumor Reveals Insane Peter Parker Twist And It's Dividing Fans - Spoilers

An insane new Spider-Man: Brand New Day rumour claims to reveal a major Peter Parker twist, shaking up his status quo in the MCU heading into the MCU's next Saga of storytelling.

There have been a lot of wild Spider-Man: Brand New Day rumours, with the biggest being that Sadie Sink is playing the MCU's Jean Grey. Fans have been left scratching their heads over Marvel Girl's involvement, especially as it appears she's the movie's main antagonist.

The Department of Damage Control is expected to be a major threat for the X-Men down the line, with the organisation likely responsible for creating mutant-hunting Sentinels. The organisation manipulating Jean makes sense, and her psychic powers would explain why the Hulk goes savage and battles the web-spinner.

Still, she's an odd fit for a Spider-Man movie, especially as Peter Parker has no real history with Jean to speak of. Tom Holland has said he pushed for Sink's character to be included in Brand New Day, and a new rumour may reveal why.

We'll preface this by pointing out that this claim comes from 4chan, a notoriously unreliable source of information...that's also been the source of many reliable leaks over the years. That's why we're not dismissing this one completely out of hand.

So, take this with a pinch of salt, but the rumour claims Jean Grey is in Spider-Man: Brand New Day, and that she'll reveal that Spider-Man is also a mutant. The spider bite awakened his mutant gene, just as the Mind Stone activated the Scarlet Witch's powers and Kamala Khan's bangles made her Ms. Marvel. 

The changes Peter is going through are a secondary mutation, and the plan is for Spider-Man to bridge the gap between the old and new MCU. This was in the works for Ms. Marvel, but it sounds like the response to The Marvels changed that. If it's anywhere close to true, it would certainly explain why Jean is debuting in Spider-Man: Brand New Day years before the X-Men reboot is released.

We'd be remiss not to point out filmmaker Destin Daniel Cretton's history with the DODC, as Wonder Man strongly hinted that Simon Williams might be a mutant.

Back to Spider-Man, and Marvel Comics will reportedly follow suit, with the upcoming DNX event set to establish that Spider-Man has been a mutant all this time. It's hard to picture, but this could open the door to Spidey joining the ranks of the X-Men on the page and screen.

Needless to say, this has divided opinions, with many fans expressing unhappiness with the notion of such a major change being made to the wall-crawler. Marvel Studios has, however, left the door open to this being possible by never actually revealing Peter's origin story in the MCU.

On a related note, Daniel Richtman has said that the mysterious "VMax" we've heard so much about is mentioned during Spidey's meeting with Yelena Belova in Spider-Man: Brand New Day

Do you think this rumour is true, or is it complete nonsense? As always, we want to hear your thoughts in the comments section below.

During the Infinity Saga he was Iron Man Jr., and now he's an X-Men honorary member; I miss when Spider-Man was his own character, as now it seems like they don't think he's good enough to stand on his own.

@TheJok3r - when played by tom holland he's 100% not good enough to stand on his own. they should have just merged andrew garfield in from the start.

@ferf - He's a good supporting actor, but he can't lead a movie to save his life. They should've used the ending of No Way Home to phase him out of the MCU and bring in an actor who can actually carry a franchise.

Really confounding that they would allow this under any umbrella. Why start off the mutant saga with such a sour [frick]ing taste??

I am a hundred and ten percent against this. It takes away what makes Spidey unique. No. I really am hoping they don’t go down this road. Wow. And the comics doing the same thing?! He’s been with the X-Men many times before and him being a mutant or not had nothing to do with it.

I mean, this isn’t anything new. Marvel Comics has been trying to tie Spider-Man to the X-Men for years. Ultimate Spider-Man was made an honorary member of the team, Spider-Man and His Amazing Friends paired him with two mutants, and a lot of kids who grew up with that show genuinely thought he was a mutant. Even in the main Earth-616 universe, Marvel occasionally teases the idea, but it never really sticks.

Spider-Man has his own corner of the Marvel Universe, separate from the X-Men, and that’s how it should be. If they make him a mutant, the character loses a big part of what makes him unique. It’s the same mistake they made with Ms. Marvel. There are already hundreds of mutant characters in the Marvel Universe, so there’s no reason to turn established non-mutant heroes into mutants. It doesn’t add anything to the character it just undermines their original identity.

Sounds similar to the crossover episode between the animated Spectacular Spider-Man and X-men 1997 when Peter went to ask Prof X for help with his progressing mutation into man-spider. The X-men naturally assumed that Peter was a mutant.

Originally, Peter was bitter by a radioactive spider that mutated his genes. That's why they used the word radioactive. This would be a small departure

As comic accurate as the MCU has been, why would anyone believe this? The MCU sticks to the origin stories pretty good. There’s no reason to change that at all, especially starting now.
And what happens when it comes out that Sadie Sink is NOT playing Jean Grey? It should be a WHOLE LOT less rumors on this site because every shred of credibility is in the toilet at this point.
And let’s not forget that Sebastian Stan was CONFIRMED as Harvey Dent based off of zero evidence. They even gave him a wife in Scarlett Johansson and a dad in Charles Dance based off of nothing, even though the director, himself said “This villain has never really been done on the big screen before”.
