This movie will also introduce us to two new alien lifeforms , the Skulls and the Kree, ,
well kinda , the Kree have been around in a couple of their movies so far , like Ronan from the first Guardians of the Galaxy
but the Skulls will be new , the Skulls and Kree have been at war with each other for ever
The Skulls are shape shifters , hence , Captain Marvel punching the old lady on the subway , that was probably a Skull in disguise
but seeing how this movie takes place in the 1990's , you'll find out that Skulls have been on Earth since before the first Iron man movie
, which , could change alot of what you thought you knew, from all the prior Marvel films , maybe not eveyone is who you think they are
just a guess
