As production for "Captain Marvel" gears up, more and more details about the movie have popped up. The latest one are character descriptions that shed light on some of the Skrulls that Brie Larson's Carol Danvers could be going up against in the upcoming film.

The Hashtag Show" obtained character descriptions from a casting call for what seems to be a female fighter and two male soldiers. Check them out below.

"[Alpha] Female, 20-49. Fight experience. Dance or gymnastics preferred.

[Delta] Male, 20-49. Must be over 6′ tall, broad shouldered and muscular.

[Supporting Male #2] Male, 35-45, a chiseled, cocky guy who is large in stature, but not as big as Delta."

The publication believes that the Supporting Male #2 is Titannus. He is a Skrull born without the alien race's iconic shapeshifting abilities who ultimately ends up gaining super strength and healing factor after taking part in the Super Skrull experiments. In the comics, he crash-lands in Japan where he later fights with the Avengers, something that could play into "Avengers 4," which was confirmed previously to be partially shooting in the Asian country.

As for Alpha and Delta, The Hashtag Show theorizes they could be Princess Anelle and Dorrek VII, respectively. Both are key players in the Kree-Skrull war, with Dorrek ruling his race and Anelle his daughter. Anelle and Mar-Vell, who will be played by Jude Law in the film, fell in love in this arc and shared a child who grew up on Earth as Teddy Altman, later known as Young Avenger Hulkling.

"Captain Marvel" is expected to feature a heavy dose of Skrulls, but they will not be the only nefarious forces. Krees may also share the spotlight as Ben Mendelsohn is reportedly in talks to play the film's main villain, Kree Colonel Yon-Rogg.

When it comes to personal conflict, the Kree officer may be the main antagonist in "Captain Marvel." However, the Skrulls should still have the numbers that threaten to overwhelm Earth.

"Captain Marvel" is set to kick off production in February for a March 8, 2019 release.
