While Gamora and Nebula were two fun female characters entering the Marvel universe, it seems like director James Gunn wants to keep adding female roles to his sequel to Guardians of the Galaxy, which could mean a few big comic names could be popping up.

According to Collider on Monday, during Dragon Con, one fan asked Gunn about any new female superheroes entering the Marvel universe in Guardians of the Galaxy 2 and the writer/director seemed excited to be adding more than just a few.

"While he agreed that more than likely, Carol Danvers would appear sooner rather than later in the Marvel movies, there were plenty of other women in the comic book roster of the Guardians of the Galaxy and he was more than excited to begin introducing them into future films," the site said.

"The plan, according to Gunn, is to introduce new female characters into the world of Guardians as soon as he could."

MTV speculated on a few heroines who could join the Guardians world with four names that would make the most sense: Martyr, Moondragon, Mantis and Angela.

The one name that could work best in the sequel is Moondragon. MTV talks about the history of the character saying, "Didn't Drax's personal story feel a little undercooked? Ronan didn't remember killing his family, and then he did, but Drax wants to go after Thanos, who killed his wife and daughter in the comics.

"It's possible that the sequel could introduce the twist that Thanos actually did kill Drax's wife, but not his daughter. In the books, Drax's daughter grows up on Thanos' home moon and becomes Moondragon after the attack that leaves her parents dead. Introducing Moondragon would have big implications for Drax and perhaps bring some closure to his story."

This would allow a tie between the story of Drax and Thanos that was hinted during the first movie and could add another strong, fighting female role to the movie.

Guardians of the Galaxy 2 is set to open in theaters on July 28, 2017.
