The One Reason Spider-Man Is Different From X-Men's Mutants

Spider-Man: Brand New Day (2026) is here, and it's expanded the lore for both the Wall-Crawler and the Marvel Cinematic Universe's version of the X-Men. This is the first time a Spider-Man movie has made it to a fourth film, and they've pulled out all the stops with Sadie Sink officially playing the powerful mutant telepath, Jean Grey.

But considering these are both characters with powers, it begs an age-old comic book question of why Spider-Man isn't considered a mutant when, as Brand New Day shows, he's mutating as well. There's actually an answer for why that further proves how silly Marvel civilians are for hating mutants.

What Is A Mutant In The Marvel Universe?

Mutants in the Marvel Universe make up a small population of the human race and have existed as early as Ancient Egypt, with Apocalypse constantly being hailed as the first mutant. Coined Homosuperior by Magneto, they are people born with an X-gene in their DNA passed down through generations.

Not everyone with the X-gene will become mutants, but what awakens these abilities is often great stress during puberty. Jean Grey, for example, had her powers awakened when she saw her best friend die after getting hit by a car.

Mutants have no control over how their mutations will change their appearance or the powers they will get, and some are unlucky enough to change into something wild, like Beak or Glob. People often fear mutants because it makes them question if their own human existence is threatened, though this is far from justified. The persecution mutants have endured from the Sentinel Program to anti-mutant rhetoric from the likes of William Stryker or Henry Gyrich has been brutal and long-suffered.

What Is A Mutate In The Marvel Universe?

Aside from the X-Men, most of Marvel's greatest heroes are mutates, which is when an individual gains powers through external means. While the external means are typically a form of radiation, like Spider-Man, Hulk, and the Fantastic Four, others got it through different sources.

For example, Black Panther and Captain America gained their powers through herbs and serums, while Deadpool acquired his healing factor through brutal experimentation. All in all, they were never going to have powers if it weren't for some manipulation. Nevertheless, the average person wouldn't know that.

In the case of Spider-Man, mutates can evolve further, as Spider-Man: Brand New Day proves when Peter Parker develops organic webbing and even more heightened senses. This also goes for the Hulk, who has proven that, with time, he's not only gotten stronger but is also immortal. 

But with so few knowing the origins of Marvel's best heroes, it makes mutant hate redundant because, by their logic, any mysterious hero with powers could be a mutant or mutate, but they'd never know. It's become a huge point of contention in Marvel Comics. It has only succeeded in making characters like Cyclops very protective of his kind, to the point of violence, and justifiably so.

Hulk Is The Perfect Mentor For Spider-Man In 'Spider-Man: Brand New Day'

With Jean Grey being in Brand New Day and Peter Parker going through a mutation of his own, it would make sense that she would be the best person to talk him through it. But in reality, their abilities and origins couldn't be further from one another, and one is even more powerful than the other as well. On top of that, Jean is still learning how to control her abilities alone.

Ultimately, Jean Grey works better as a character who shows the result of a natural mutation. However, Bruce Banner is a much better fit as a mentor and aid through Peter's changes. He spent most of his adult life dealing with the effects of an external force changing his DNA and has spent years trying to eradicate, suppress, and coexist with what changed him.

Banner is still mutating, and as Peter navigates these new changes, it would make the most sense to have someone who also changed in ways his body wasn't prepared for to help him understand it. Unfortunately, the average mutant won't relate to what a mutate goes through, as their problems are different from one another. But Bruce Banner proved he is still the best person for Peter to learn from.
