Since we had precedent that Thanos liked to 'save' little girls from his genocides and raise them as his daughters, including the line from GOG1 from Nebula "Of all of our sisters, I hated you least,' there certainly could have been a Moondragon, the former daughter of Drax, Kymera (sp?), raised by Thanos as one of his daughters, and maybe empowered by the Mind Stone (which was in his possession before he lent it to Loki, and, again, precedent with the Scarlet Witch and Quicksilver showed that an Infinity Stone could be used to kickstart powers in people, which, if even Hydra could just sort of figure it out, certainly *Thanos* could have done!).
It would have flowed interestingly with the whole 'family' theme that was running through both Guardians films, having Drax encounter his fully-grown daughter, raised by his worst enemy and perhaps convinced that he abandoned her to that madman's clutches.
Missed opportunity, IMO.
But really, the list of Guardians I would have wanted to see other than Mantis starts with Cosmo and ends with Aleta, and Nikki's on it twice.
The 'whore' line super bugged me, not *only* for being tone-deaf, but because it came after it was excruciatingly pointed out that Drax's people are completely literal and incapable of metaphor. So he couldn't call Gamora a whore
unless he actually thought she was a prostitute. Which he didn't.
Murderer. Killer. Psychopath. Assassin. Butcher. Any of those could have passed. But 'whore' was completely wrong for him to say, after the whole 'completely literal' thing.
And yeah, *also* offensive. :/
