The Guardians of the Galaxy Holiday Special is set to push Mantis and Drax into the forefront, and a new revelation about the identity of Star-Lord's sister may have shed some light on the impact of the Disney+ special on its MCU characters. 

The upcoming Special Presentation will bring Christmas cheer to the MCU as Mantis and Drax head to Earth to find the perfect gift for Peter Quill. The journey back to Earth presents many opportunities to find out more about the history of these two Guardians, more so with the ever-mysterious backstory of Mantis. 

Pom Klementieff's Guardian was first introduced in Guardians of the Galaxy Vol. 2 when the team finds her on Ego's planet. While she did help the Guardians to defeat Ego, minimal details about her history have since been revealed. 

And now, a surprising new reveal has finally been unearthed that potentially explains why the character decides to return to Earth for Quill's Christmas gift. 

Who is Star-Lord's Secret Sister?

At the end of Mantis' episode of Marvel Studios Legends, a deleted scene between Pom Klementieff's MCU heroine and Drax from Guardians of the Galaxy Vol. 2 became part of the recap. 

In the scene, Drax promptly asks Mantis why she doesn't want to tell Peter Quill that she is his sister. Mantis then told Drax that their only connection is "the source of his greatest shame" so she doesn't see the need to tell him: 

Drax: “Why don’t you want me to tell him?”
Mantis: (shrugs)
Drax: “He should know you are his sister.”
Mantis: “Our only connection is the source of his greatest shame. I think not.”

The scene confirmed that Mantis is a daughter of Ego, thus making her the half-sister of Star-Lord.

Will Mantis Finally Tell Star-Lord Her Secret?

Disney+ might've included this deleted scene in the latest Marvel Studios Legends episode to set up the eventual reveal that Mantis will finally tell Peter Quill that she is his half-sister. 

It is unknown how Star-Lord would react to the news. However, given that they've been together as teammates for quite a while now, there's a good chance that he would wholeheartedly accept Mantis' revelation. 

Moreover, it's possible that Drax and Mantis will not be successful in retrieving Kevin Bacon in the Holiday Special. Instead, Mantis revealing to Quill that she is his half-sister would be an incredible Christmas gift that would cap off the holiday adventure. 

Mantis being Star-Lord's sister would instantly change the dynamic between the pair. 

Karen Gillan and Pom Klementieff admitted that the threequel's script made them cry, thus suggesting that the threequel will be an emotional affair. That said, Mantis and Star-Lord's emotional bond will be tested as they face one of their most dangerous villains yet, The High Evolutionary. 

The Guardians of the Galaxy Holiday Special is set to premiere on Disney+ on Friday, November 25.
