While most of Avengers: Endgame is still being kept secret even with it arriving in a little less than four months, one of the things we can definitely look forward in the final Phase 3 installment is Carol Danvers, a.k.a. Captain Marvel, teaming up with Avengers: Infinity War's surviving heroes. It's quite the next step forward following her first MCU appearance in early March, and Captain Marvel co-director Ryan Fleck is looking forward to the prospect of Carol coming to blows with Thanos in Endgame. As Fleck put it:
At the beginning of our movie, she doesn't know how powerful she is. But by the end, you'll see that, uh... let's just say this, I'm very excited to see what she does to Thanos in Endgame.
Ryan Fleck teased Carol Danvers' power levels while speaking with AMC Theatres alongside the other Captain Marvel co-director, Anna Boden, but it should be noted that Fleck wasn't divulging any insider information Avengers: Endgame, and he was likely speculating as a fan when making his comment about Carol and Thanos. That being said, if Brie Larson's version of Carol is as mighty as Fleck is hinting, then one can assume that the chances of her throwing a punch or two at the Mad Titan are stronger than not.
This isn't the first time we've heard about just how powerful Carol Danvers is in the MCU, as last year, Brie Larson noted that Carol has the ability to move planets. The only feat we've seen in this franchise that comes remotely close to that is Thanos using a moon as a projectile in Avengers: Infinity War, and he needed an Infinity Stone to make that happen. Carol can accomplish that and then some without any aid.
Still, let's not forget that although the Infinity Gauntlet was damaged at the end of Avengers: Infinity War, all six Infinity Stones are still intact and in Thanos' possession. It's possible that their powers have diminished after Thanos carried out his genocide, but regardless, while Carol has the ability to go mano a mano with him, presumably it will still be a difficult battle for her, assuming these two even face off against one another.
Before Carol Danvers crosses paths with the other MCU heroes and aids them in undoing Thanos' slaughter of half of all life in the universe, we'll learn about her origins more than two decades ago in Captain Marvel. Set in 1995, the penultimate Phase 3 movie will show Carol as an operative for the Kree military team Starforce. But upon being drawn back to Earth, she'll uncover the secrets of her past, i.e. how she went from a fully human U.S. Air Force pilot to a half human, half Kree noble warrior hero, and all while she prevents her homeworld from being overtaken by the conflict between the Kree and the Skrulls.
Captain Marvel flies into theaters on March 8 and Avengers: Endgame will follow on April 26. For everything else the MCU has in development, check out our handy guide.
