All the news and artwork coming out of Marvel’s Guardians of the Galaxy is really intriguing. When last we reported mid-March we told you that Dave Bautista had been cast as Drax the Destroyer and he would be joining Chris Pratt as Star-Lord. Now one of our favorite Star Trek leading ladies is in talks to join the crew.

Star Trek and Avatar heroine Zoe Saldana is said to be in talks to join the cast as the female lead, according to THR. Here’s what they said about her character.

Saldana would play Gamora, the green-skinned humanoid who is the last of a species that was exterminated by a race known as the Badoon. She also happens to be a skilled assassin.
