Peter Quill built a family out of an unfamiliar universe, but now it's time for Guardians of the Galaxy's Star-Lord to meet the man who gifted him a Y chromosome (and a little alien DNA to boot). If our earth-bound family reunions are chaos, you can only imagine what's in store for the pilot of the Milano.

Guardians of the Galaxy Vol. 2 will introduce viewers to Kurt Russell's Ego. Although Quill's (Chris Pratt) father is canonically known as the Spartoi Emperor J'son, the MCU will breath new life into the story with the arrival of the Living Planet.

"It's different than what's in the comic books," writer/director James Gunn teased, according to Uproxx. "Peter Quill's father is somebody different in the comics."

Russell commented on his role while attending the Toronto International Film Festival, promising a new set of dilemmas for the leader of the Guardians.

"It's a very complex story and they really get into it," Russell told Collider. "Peter's character in this one, he's got dilemmas and he's got decisions to make that are not just about whether to save that thing or that person. This is about finding out who you are, where you come from, and where you're going."

Unlike many of the Avenger-based films, Vol. 2 will dive deep into the well of biological family.

"It's more connected to human issues, family issues, parental issues, and issues that sons and daughters have with their Moms and Dads and their family tree, where they come from," the actor teased. "I just think it's going to be an interesting."

For fans, Pratt believes the 2017 film will deliver above and beyond expectations - Thanos or no Thanos.

"I can say Guardians 2 is going to be out May 5. It's finished and it's going to be terrific. I'm already so proud of it. We worked really hard on it and it's a joy to be part of," Pratt told The Toronto Sun. "It's a fabulous script. I think it's going to be - I'm not using hyperbole, here - I think it's going to be the biggest spectacle movie of all time."
