The Marvel Special Presentations that are available to people with a Disney+ subscription are allowing the MCU to expand on corners of its world while also filling in gaps of Marvel mythology. The shorts featured in "I Am Groot" show the tree creature growing up and dealing with various issues. Michael Giacchino’s "Werewolf By Night" recreated the 1940s Creature Feature while also introducing Man-Thing and opening the door to monsters in the MCU. And now, in the upcoming "Guardians of the Galaxy Holiday Special," creator James Gunn is revealing a secret he has had Pom Klementieff sitting on since the moment she accepted the role of Mantis.

There has been speculation in the MCU community that Mantis might be the sister of Peter Quill (Chris Pratt), because their shared “father,” Ego the Living Planet (Kurt Russell) had children with women all over the galaxy in hopes of finding an heir that could access the Celestial power the way that Star-Lord could. At one point, when Ego was laying out his plans, there was a mural of all of the women that Ego had impregnated. And fans noticed that one of them definitely looked like Mantis.
