So famously Ike decided to elevate The Inhumans after his "no more mutants" edict pre-Fox merger. Since Feige was in charge of the movies and untouchable by Ike due to him having Disney's untouchable status, Ike leaned hard into the TV arm which Feige didn't control at the time. This is why Inhumans went from a movie into truly one of the worst superhero TV shows of the modern era. As Feige's role was elevated to basically being the go-to guy for Marvel writ large, The Inhumans were largely purged from the comics and Kamala and Moon Girl were really the only Inhuman characters left standing after all this went down. Marvel has now quidrupled down on mutants and rather than write Kamala's Inhuman nature into her character (even though Agents of S.H.I.E.L.D. provided a matrix through which to do it) they just turned her into a Green Lantern.
