Pom Klementieff has landed a major role in the heavily anticipated sequel for Marvel’s Guardians of the Galaxy, but who she’ll play remains a secret.

Marvel conducted an intense search for the right actress for the mystery part in which Klementieff was cast, according to The Hollywood Reporter. The studio had been searching for an Asian actress for the role, and had held several rounds of chemistry reads before deciding that Klementieff was the right person for the job.

Marvel has remained tight-lipped on the details of Klementieff’s role, as well as the plot for Guardians of the Galaxy 2. But, which of the characters in the galaxy could Klementieff have been tapped to play?

The most likely comic book candidate is Mantis, the German/Vietnamese “Celestial Madonna,” who joins the Guardians of the Galaxy, according to HitFix. In addition to being superhuman in just about every way, Mantis also possesses telepathic, telekinetic and pyrokinetic abilities.

Moondragon comes in as a close second possibility for Klementieff’s first major blockbuster part. In the comics, Moondragon is the long lost daughter of Drax the Destroyer, who grew up on Earth as Heather Douglas. Eventually, she makes her way to the planet Titian and competes with Mantis for “Celestial Madonna” status. Like Mantis, she’s both telekinetic and telepathic – but she can also shapeshift into a dragon.

Other possibilities include Aleta Ogord aka Starhawk and Phyla Vell.

Klementieff is relatively unknown stateside, but has done work in French cinema. Her one major English-language project to date was Spike Lee‘s remake of Korean thriller Oldboy.

With Guardians of the Galaxy 2, Marvel is looking to recreate the success of the 2014 original, which grossed $774 million at the global box office. Returning for the sequel are stars Chris Pratt as Star-Lord, Zoe Saldana as Gamora and Dave Bautista as Drax, as well as Bradley Cooper and Vin Diesel, who voice Rocket Raccoon and Groot, respectively.

Guardians of the Galaxy 2 is slated for release May 5, 2017.
