It Looks Like Mantis WAS Originally Star-Lord's Sister in the MCU

It looks like Mantis was intended to be Star - Lord ’s sis - at least in the developing ofGuardians of the Galaxy Vol . 2 . Director James Gunn recently confirm thatanother of Mantis ' speciesappeared inGuardians 2as one of Ego ’s many , many love interests , but he seemed to err away from suggesting this was Mantis ' female parent ( and thus making Mantis Ego ’s daughter and Peter Quill her half - brother ) .

In the releasedGuardians of the Galaxy Vol . 2,Mantis ' backstoryis rather simple : she was come up by Ego when just a larva and was conjure up on his planet , kept around to allow for the Celestial being to sleep . She witnessed his repeated attempts to find an heir powerful enough to serve him take over the universe , eventually turn on her master - turned - capturer with the Guardians .

However , it may have earlier been more complex . Jennifer Sharp , the actress who played the microbe alien whom Ego romanced , posted on Instagram ( viaReddit ) a picture of her on the primed ofGuardians of the Galaxy Vol . 2captioned " It was an honor to work with Kurt Russell even for a short flashback scene in Guardians of the Galaxy Vol 2 as Mantis ' Mom(even though the scene was cut ) . " Since Gunn ’s check of the Easter egg and pink slip of Mantis ' relation to Ego , however , that ’s been edited to remove any citation of a flashback scene or her family relationship to Mantis ( and also chasten the grammar on the shortening of " Volume " ) .

It ’s entirely possible that Sharp was merely strike her fictitious character ’s parentage of Mantis based on them being the same metal money - indeed , as the role was presumptively a single take ( Gunnlater said she was a fashion model for theCGI of Ego ’s whirl ) then she may not have been given full information of the case . This would make the earlier post inaccurate and the edit a correction .

However , given how tight the idea that Mantis is Ego ’s issue - and was kept around only because of her power to help him residue - it ’s possible that this was once the plan in the cause ofGuardians of the Galaxy Vol . 2but was then pulled back to instead be equivocal or otherwise a mystery . The only word prior to this week was Jennifer Sharp saying she was Mantis ' mother , and Gunn has n’t explicitly said sheisn’t , just that it should n’t necessarily be infer - something the edits to Sharp ’s Instagram also suggest . As the detail is so flimsy , it could have never actually have meant to be reassert .

As for why matter are being avoided now , it may be done to allow a retcon of the fact down the line , but could also be to hide aGuardians of the Galaxy Vol . 3twist . If Mantis is Star - Lord ’s half - sister , then that could have some jolly serious ramifications for the self - defined folk team and their third dangerous undertaking .
