Like tbh, Magneto wouldn't even need to be that involved in the secret. If he saves his people via asteroid and he's up there and sees all you people coming into space he'd scatter your asses anyway. Although his whole point in space will be to collect mutants who have been scattered. So let's just go with Reed Doom fucking it up? Does he generally hate everybody enough to do that just to do it or does it have to involve his hateon for the FF? My most vivid comic memories of him are the marrying Wanda and letting Squirrel girl use his library.
...It hadn't even occurred to me for Howling Commandos omg. Nick would proooobably want the resources of Nova Corps but not want to not...be in charge. So maybe he'd get himself in there then steal some ships and stuff like 'lol' and he and Jasper could run off doing Howling Commandos stuff?
