Ewing finding stuff from the past to somehow make Moira X work like he did with the TOBA related retcons in Immortal Hulk would be beautiful if he managed.
And it's even weirder to change Moira this much for the people who did like the retcons around her, so the people who liked a callous Moira who was behind everything becoming better (Even if there were hints she's not 100% doing it for mutants and could become a villain) now have to put up with this Omega Sentinel 2.0.
What's gonna happen later? If by any chance Omega Moira is liked, will Marvel change her into something completely unrecognizable too? Shit, this is some Gwen Stacy kind of personality changes, and Gwen made more sense, and I don't say that lightly lol.
