Last month, we reported that Oscar winner Matthew McConaughey turned down the villain role in Guardians of the Galaxy Vol. 2, while the highly-anticipated sequel added its first new cast member Pom Klementieff, who is reportedly playing Mantis. Pre-production is currently under way in Atlanta, as writer-director James Gunn prepares to start principal photography early next year. One of the biggest questions swirling around this superhero sequel is the identity of Star Lord's (Chris Pratt) father, which will be revealed in the movie. All we know for sure is that it won't be the same character as it was in the comics, J'son. Today, we have a new rumor from Heroic Hollywood, which has revealed the identity of Peter Quill/Star-Lord's father. Be warned, there will be potential SPOILERS below, so read on at your own risk.

The site has revealed, through four independent sources, that Star-Lord's father is none other that the first Captain Marvel, not Carol Danvers, but Mar-Vell, who first appeared in Marvel Super-Heroes #12 in December 1967. In the Marvel Comics, Mar-Vell was sent to Earth by his Kree commanding officer Colonel Yon-Rogg, to determine whether or not the human race posed a threat to the Kree. In the Guardians of the Galaxy, Star-Lord's father was described as an angel, composed of light, who is part of a race that the Nova Corps hasn't seen in several years. Heroic Hollywood speculates that Marvel may be doing some serious tweaking to Mar-Vell's comic book back story, to fit him into the MCU.

You may recall that Carol Danvers, who is getting her own stand alone Captain Marvel movie in 2019, was originally set to be introduced in Avengers: Age of Ultron. Producer Kevin Feige revealed after the release that this plan was scrapped because they didn't want to introduce her before fans knew "how she came to be." In the comics, Carol Danvers actually gets her powers from Mar-Vell, after both Carol and Mar-Vell were caught in the explosion of a Kree Pscyche-Magneton device, which caused her DNA to become fused with Mar-Vell's, causing a perfect hybrid of Kree and human genes.

If this rumor is true, it's possible that the introduction of Mar-Vell in Guardians of the Galaxy Vol. 2 may be leading up to an appearance in Captain Marvel, where he could play a significant role in her origin story. The site also speculates that Mar-Vell is actually the role that Matthew McConaughey turned down, since the studio most likely wanted to secure the actor for multiple appearances, instead of for "one-off villain." Since we never learned exactly what role Matthew McConaughey was offered, it isn't known if he was up for Mar-Vell or not.

Since, in the comics, Mar-Vell isn't an angel composed of light, the site also speculates that Marvel will be altering his origins, turning him into one of the Inhumans. The site speculates that Marvel wants the Inhumans to be their next X-Men, and even though we still have four years until the Inhumans movie arrives in July 2019, the Inhumans race as a whole have already been set up on Marvel's Agents of S.H.I.E.L.D. None of this has been confirmed quite yet, but the site also mentions that they expect denials from the Marvel camp. Do you think Star-Lord's father could be Mar-Vell?
