New set photos from Marvel Studios' Avengers 4 gave fans their first look at Brie Larson suited up as cosmic superhero Captain Marvel, but with a twist: the Academy Award-winning actress was captured sporting a suit reminiscent of the uniform worn by the original Captain Mar-Vell in the classic Marvel comics.

The suit, which is likely not Danvers' final comic book-inspired look first seen in the initial concept art, comes from Danvers' ties to the alien race known as the Kree.

Online reactions to the suit were mixed to positive — a subsequent fan-edit even gave Larson's Carol Danvers a suit more familiar to modern comic book readers — but the photos have given rise to a new hashtag, #KreeLarson, established in support of the Academy Award-winner's unofficial debut as the half-alien superhero.

Larson has been hard at work researching her role as a member of the United States Air Force-turned-superhero, visiting with service members at Nellis Air Force Base in Las Vegas, Nevada.

Fan support for Larson has been strong since the actress was announced as Danvers in July 2016, making her the first woman to play the title character in a Marvel Studios production.

The 28-year-old actress was initially hesitant to accept the role, admitting it took her a "really long time" to board.

"Ultimately, I couldn't deny the fact that this movie is everything I care about, everything that's progressive and important and meaningful, and a symbol I wished I would've had growing up," she said.

Larson is encouraged by the largely positive response to her casting, explaining in September she understands the importance of tackling an iconic Marvel heroine.

"It requires so much physically, and it's a lot longer shoot, and there's also the pressure because this is a character that is incredibly inspiring to people and means a lot," Larson said. "So you just want to get it right. I feel really excited about how everything is shaping up."

Captain Marvel most recently brought aboard She's Gotta Have It star DeWanda Wise, who joins the cast alongside Jude Law (Fantastic Beasts: The Crimes of Grindelwald), Ben Mendelsohn (Rogue One), and Marvel Cinematic Universe veteran Samuel L. Jackson, who reprises his role as Nick Fury.

Mississippi Grind filmmakers Anna Boden and Ryan Fleck direct from a script by Meg LeFauve (Inside Out), Nicole Perlman (Guardians of the Galaxy), and Geneva Robertson-Dworet (Tomb Raider).

Larson makes her debut in Captain Marvel, out March 8, 2019, before reprising the role in Avengers 4, out May 3, 2019.
