BLACK WIDOW WILL INTRODUCE MUTANTS To MCU
Makes sense since, from now on, Marvel Studios can introduce members of the Mutant race in the cinema or Disney+ series.
Before 2019:
Debut of members of the Asgardian race in the cinema
Debut of members of the Xandarian race in the cinema
After 2019:
Debut of members of the Eternal race in the cinema
Debut of member(s) of the Mutant race in the cinema? Confirmation of members of Mutant race e.g. Scarlet Witch and Quicksilver?
Debut of member(s) of the Inhuman race on Disney+?
Before 2019:
Debut of super hero team Avengers in the cinema?
After 2019:
Debut of super hero team Fantastic Four in the cinema or Disney+?
Debut of super hero team X-Men in the cinema or Disney+?
Like in the comics, members of the super hero team 'X-Men' can be non-mutants e.g. Calvin Rankin aka Mimic and Longshot
