Warning! This post contains SPOILERS for Spider-Man: Brand New DayThanks to Spider-Man: Brand New Day, the X-Men’s Jean Grey has officially made her MCU debut. Played by actress Sadie Sink, Jean is surprisingly revealed to be the movie’s primary antagonist, having been put on a darker path of vengeance for what was done to one of her loved ones. Additionally, Marvel Studios has seemingly confirmed a huge part of Jean’s mutant status in the MCU ahead of the upcoming X-Men reboot.
In Spider-Man: Brand New Day, Sadie Sink’s debut as Jean Grey establishes a very new version of the character while also setting the stage for the MCU’s upcoming X-Men reboot from director Jake Schreier. As part of that key set-up, Spider-Man: Brand New Day’s ending leaves audiences with a far more powerful version of Jean than the one they were introduced to at the beginning of the movie.
Featuring a major on-screen evolution of her powers by the movie’s end, it seems very likely that Sadie Sink’s Jean Grey is not only one of the first mutants native to the MCU’s main timeline of Earth-616, but its very first Omega-level mutant as well.
Jean Grey Makes An Impressive (Yet Underpowered) MCU Debut In Spider-Man: Brand New Day

Despite being a classic X-Men hero in the comics and in past Marvel movies, Sadie Sink’s Jean Grey is surprisingly revealed to be the primary antagonist of Spider-Man: Brand New Day (at least at the onset). Despite her sympathetic motivations searching for her secretly abducted sister by the Department of Damage Control, Jean’s isolation sees her darkly determined to do whatever is necessary to get her sister back.
Like Jean, Sara Grey’s status as a gifted telepath explains why the DODC captured her and subsequently subjected Sara to a series of brutal experiments in an effort to replicate her abilities.

01
Before getting his own solo film, Tom Holland’s Peter Parker made his Marvel Cinematic Universe debut by being recruited by Tony Stark to help in a massive superhero conflict. In which MCU film did Holland first appear as Spider-Man?
✓ Correct! Tom Holland first appeared as Spider-Man in Captain America: Civil War (2016), where Tony Stark visits Peter in Queens and recruits him for the airport battle against Team Cap. His quippy, starstruck portrayal instantly won over audiences.
✗ Web miss! The answer is Captain America: Civil War. Holland debuted in the 2016 film before Homecoming (2017). He was recruited by Tony Stark for the iconic airport fight scene, stealing Captain America’s shield with his webs in one of the film’s most memorable moments.
02
In Spider-Man: Homecoming, Peter faces a blue-collar salvage contractor who turned to arms dealing after being shut out of the Chitauri cleanup by Damage Control. Using an alien-tech wingsuit, he becomes one of Spider-Man’s most grounded villains. Who is he?
✓ Correct! Adrian Toomes, played brilliantly by Michael Keaton, is the Vulture — a working-class father who builds a criminal empire selling alien-derived weapons. The twist that he’s the father of Peter’s date Liz is one of the MCU’s best surprises.
✗ Web miss! The answer is The Vulture (Adrian Toomes). The Shocker and Tinkerer are his henchmen in the film, and Scorpion (Mac Gargan) only briefly appears. Toomes is the main antagonist who personally confronts Peter in the unforgettable car ride scene.
03
Tony Stark built Peter a high-tech suit loaded with features Peter didn’t even know about, including an AI assistant that helps him in combat, provides tactical analysis, and even gives dating advice. What name does Peter give this AI?
✓ Correct! Peter names his suit’s AI “Karen,” voiced by Jennifer Connelly. She assists him with web shooter modes, reconnaissance, and even his love life. Friday is Tony Stark’s AI, and E.D.I.T.H. is the Stark satellite system that appears in Far From Home.
✗ Web miss! The answer is Karen. Friday is Tony Stark’s personal AI, E.D.I.T.H. is the Stark defense satellite Peter inherits in Far From Home, and Jocasta is an AI from the comics. Karen, voiced by Jennifer Connelly, is Peter’s suit assistant throughout Homecoming.
04
In Spider-Man: Far From Home, Peter encounters a seemingly heroic figure who claims to be from an alternate Earth, battling elemental creatures across Europe. In reality, he’s a disgruntled former Stark Industries employee using advanced holographic drones. What is his real name?
✓ Correct! Quentin Beck, played by Jake Gyllenhaal, is Mysterio — a master of illusion who uses Stark Industries’ B.A.R.F. holographic technology and weaponized drones to fabricate the Elementals and pose as a hero. His final act of revenge shapes the entire third film.
✗ Web miss! The answer is Quentin Beck. William Ginter Riva is one of Beck’s team members, Aldrich Killian is the villain of Iron Man 3, and Justin Hammer is from Iron Man 2. Beck is Mysterio, the illusionist who manipulated Peter’s trust across Europe.
05
In one of the MCU’s most shocking mid-credits scenes, J. Jonah Jameson broadcasts doctored footage from Mysterio’s final moments that completely upends Peter Parker’s life. What does this broadcast reveal to the entire world?
✓ Correct! Mysterio’s doctored footage, broadcast by J. Jonah Jameson (J.K. Simmons reprising his iconic role), exposes Spider-Man’s identity as Peter Parker to the entire world. This revelation drives the entire plot of No Way Home as Peter desperately seeks to undo the damage.
✗ Web miss! The answer is that Spider-Man is Peter Parker. While the footage also frames Spider-Man for the London drone attack, the earth-shattering reveal is Peter’s unmasked identity being broadcast globally by The Daily Bugle’s J. Jonah Jameson.
06
With his identity exposed and his loved ones under threat, Peter seeks help from a powerful sorcerer to cast a spell that would make the world forget he is Spider-Man. Peter’s constant modifications to the spell cause it to fracture the multiverse. Which sorcerer casts this spell?
✓ Correct! Doctor Strange (Benedict Cumberbatch) casts the memory-wiping spell at Peter’s request, but Peter keeps asking for exceptions — for MJ, Ned, May, and Happy to still remember him. These constant changes corrupt the spell and tear open the multiverse, pulling in villains from other Spider-Man universes.
✗ Web miss! The answer is Doctor Strange. While Wong is the Sorcerer Supreme and actually warns Strange against it, it is Stephen Strange who agrees to cast the spell. Wanda’s multiverse interference occurs in Multiverse of Madness, not here.
07
Throughout all three films, Peter’s loyal best friend serves as his “guy in the chair,” helping with tech support and keeping his secret. In No Way Home, this character even discovers he can open magical portals using a Sling Ring. Who is Peter’s best friend?
✓ Correct! Ned Leeds, played by Jacob Batalon, is Peter’s best friend and self-proclaimed “guy in the chair.” He discovers Peter’s secret identity in Homecoming, supports him across all three films, and in No Way Home he accidentally uses Doctor Strange’s Sling Ring to open portals to other Spider-Men.
✗ Web miss! The answer is Ned Leeds. Flash Thompson is Peter’s rival and bully who ironically idolizes Spider-Man. Harry Osborn is Peter’s friend in the Raimi and Webb films but doesn’t appear in Holland’s trilogy. Miles Morales is only hinted at. Ned is the irreplaceable “guy in the chair.”
08
At the emotional climax of No Way Home, Peter makes an enormous personal sacrifice to save the multiverse. Doctor Strange completes the spell, and when it takes effect, Peter is left completely alone. What does the final spell do?
✓ Correct! The final spell makes every person in every universe forget that Peter Parker exists. MJ, Ned, Happy, the Avengers — everyone. Peter visits MJ at the coffee shop afterward but decides not to re-introduce himself, choosing to protect them. He starts over completely alone, sewing his own suit in a small apartment.
✗ Web miss! The answer is that everyone forgets who Peter Parker is. The spell doesn’t erase Spider-Man — people still know the hero exists — but nobody remembers Peter Parker the person. This devastating sacrifice means MJ, Ned, and even Happy Hogan have no memory of him at all.

Are you an Avenger — or just a friendly neighborhood bystander?
Using her own mind-control abilities, Jean makes her MCU debut as a mysterious figure, entering the minds and controlling various civilians to stay one step ahead of the DODC and Spider-Man himself. Initially, Jean’s powers are fairly limited, as she can only jump into the minds of others within a short range of 33ft. However, things dramatically change for Jean in the movie’s third act once Spider-Man helps the DODC capture Jean (with Peter Parker not yet knowing the dark truth about the DODC, Director Metzger’s lies, and Sara’s abduction).
Why Jean’s Mutant Powers Evolve During Brand New Day’s Ending
After her capture, Jean is subjected to the same painful experimentation Metzger used on Sara, which ultimately caused Sara’s death. That tragic revelation, combined with the trauma and pain of the experiment itself, triggers an enormous evolution in Jean’s powers, expanding the range of her telepathy beyond the previous 33 feet to over a full kilometer. Jean also gains her classic power of telekinesis from the comics as well.
In the comics, mutant powers and the triggering of X-genes are historically tied to intense emotions, pain, and trauma. As such, it makes sense that Jean’s capture by the DODC would result in such a major evolution of her mutant abilities. At the same time, it’s also an important distinction for future X-Men stories in the MCU. It means Jean isn’t starting her journey as a fully established mutant hero. She’s still evolving into one of Marvel’s most powerful mutants…and there’s likely no apparent limit to how far her powers can reach.
Is The MCU’s Jean Grey Now An Omega-Level Mutant?
Jay Maidment/Sony
In Marvel Comics, an Omega-level mutant is defined as a mutant whose dominant power has no quantifiable upper limit. This means there’s no measurable ceiling for the peak of said power, placing said mutant at the top of the power’s classification. Keeping that in mind, Jean Grey herself is one of the most famous Omega-level telepaths in the comics. Other known Omega-level mutants include Professor Xavier, Magneto, Iceman, Storm, and Legion. It’s also worth noting that Jean’s Omega-level status as a telepath is not connected to her future connection to the Phoenix Force.
While the MCU’s Jean Grey hasn’t been verbally confirmed as an Omega-level mutant yet, Spider-Man: Brand New Day certainly makes a strong case after showing such a dramatic evolution of Jean’s telepathy in real time. It’s a truly enormous expansion that happens almost instantaneously, and nothing says it couldn’t happen again in future MCU stories, especially once we get more of the X-Men introduced.
For the time being, it certainly seems as though the MCU’s Jean Grey is well on her way to becoming an Omega-level mutant, even if Marvel Studios hasn’t formally used that label yet. If there’s one thing Brand New Day does to set up Jean Grey’s future, it’s proving the vast potential of her powers with an upper limit she likely hasn’t even hit yet.
Spider-Man: Brand New Day is now playing in theaters from Marvel Studios and Sony Pictures.
