Carol Danvers has been alone in space for years, investigating a strange phenomenon affecting the galaxy's jump point network. She's isolated herself, still processing the guilt of her Kree past and the people she hurt before she knew the truth. Then she uses her powers and teleports into a teenage girl's bedroom in New Jersey.
Kamala Khan—Ms. Marvel—has been manifesting light-based powers since the bangle she inherited awakened her abilities. When Carol switches places with her, Kamala is thrilled. She's meeting her hero! Carol is confused. This shouldn't be possible.
The third point of the triangle is Monica Rambeau, now a S.A.B.E.R. agent with her own light-based powers gained during the Westview incident. When she uses them, she switches with either Carol or Kamala. Three women, entangled across space, forced to coordinate their powers or trade places at the worst possible moments.
The villain is Dar-Benn, a Kree revolutionary wielding a bangle matching Kamala's. She's using the jump point network to steal resources from other worlds—air, water, the sun itself—to restore Hala, the Kree homeworld that Carol devastated when she destroyed the Supreme Intelligence. Dar-Benn blames Carol. She's not entirely wrong.
The entanglement leads to some of the MCU's most creative action sequences. Three heroes in three locations, switching constantly, having to trust each other's instincts. A fight through a Kree ship becomes a coordinated dance. A rescue mission requires split-second timing across light-years.
Carol faces her past directly. She freed the Kree from the Supreme Intelligence's control, but without their AI god, Kree society collapsed. Civil wars. Starvation. Billions dead. Carol saved them from tyranny and accidentally doomed them to chaos. Dar-Benn's rage is justified, even if her methods aren't.
The climax threatens Earth itself. Dar-Benn tears open a rift to steal Earth's sun, and Monica must sacrifice herself to seal it from the other side. She succeeds—but she's trapped in another universe, where she's found by a variant of her mother Maria, alive and apparently part of the X-Men.
Kamala officially joins the superhero community. Carol commits to helping rebuild Hala instead of running from her past. And in the post-credits, Kamala begins recruiting for a new team, approaching Kate Bishop. Young Avengers are coming.
The Marvels is slight but fun—a brisk adventure that does important work setting up future storylines while giving three heroes room to interact. Monica's exile to another universe opens multiversal doors. Carol's guilt drives character growth she's needed for years. And Kamala Khan proves she belongs alongside any Avenger. The franchise is in good hands.
