The race is on to see who, if anyone, is going to kill Thanos in "Avengers: Infinity War." Members of both the Avengers and Guardians of the Galaxy -- whom the movie will unite -- are certainly hoping for the glory that will come with killing the Mad Titan. However, Zoe Saldana, who plays Gamora, doesn't want to be the one to slay her adopted father; she wants Gamora's sister Nebula to kill him.

"I think that me, as his golden child, I sort of gave up," Saldana told Comicbook.com. "I'm done. I'm resolved. I wouldn't want anybody else to put him in the place than the first person he struck and he hurt the most which is his kids. So, I would want Nebula to do it."

"I would love to go with my sister and kill daddy dearest," Saldana jokingly added when asked whether that common goal could reunite the sisters.

In the comics, Nebula played an important role in the Infinity Gauntlet storyline, which saw Thanos successfully obtain and use the titular weapon. In that story, Nebula takes the Infinity Gauntlet from the Mad Titan's unconscious body and uses it to undo the damage he has done. However, this might not be what happens in the film, since the movies are only loosely adapted from the comics. Most recently, Drax killed the villain, but several other heroes have beaten the Mad Titan before.

Gunn and Karen Gillan, who plays Nebula, have indicated in the past that the second movie in the "Guardians" franchise will expand on the character. Gunn has also stated that he's focusing on the relationship between Gamora and Nebula, which is one of the reasons Thanos won't be in "Guardians of the Galaxy Vol. 2."

While Nebula's role in "Avengers: Infinity War" and its untitled sequel is still unknown, the character will appear in the upcoming "Guardians of the Galaxy Vol. 2," which picks up just after the events of the first film. The second installment will follow the Guardians as they struggle to keep their group together while helping Peter Quill learn about his true parentage. Early reaction to the movie has been positive, with critics touting the movie as one of Marvel's best.
