Theory Briefing
- Bill Metzger, a confirmed anti-mutant political villain from X-Men: Children of the Atom, is now an MCU character played by Tramell Tillman.
- Fans theorize Sadie Sink plays Jean Grey, whose rogue psychic powers mirror the film's central threat of an uncontrolled mind-invading mutant.
- Marvel may be using Brand New Day to seed its 'Mutant Saga' arc rather than close out the Multiverse Saga — with Spider-Man as the unlikely ambassador.
