3) Moondragon
The reasons why Moondragon should turn up in a future Guardians of the Galaxy movie speak for themselves. In the comics, she’s the daughter of Drax the Destroyer. How can Gunn resist pairing her up with her dad?
Drax’s whole motivation in the movies is to destroy Ronan the Accuser for the brutal killing of his family. But what if it turned out that his daughter hadn’t actually died, or he had another daughter somewhere else out there in the galaxy? In the comics, Heather Douglas – she’s human because, in the source material, Drax is actually a transformed Earthling rather than an alien – has an intense, humourless personality. Much like her father does at the start of GotG. It could be a lot of fun then for the mellowed Drax to meet someone much like he used to be.
As for what she could bring to the team, Moondragon has a bunch of useful skills, including telepathy, martial arts prowess and expertise in genetics. The only issue is that the team already has a badass, terse bald woman in Karen Gillan’s Nebula. Still, I’m sure they could make room for another.
