It is like how I described her
last May in the
A:IW closing credits scene. Captain Marvel is a major player. She will be the most powerful in her movie, which is why I think is one reason why they are hyping it so much as to not catch the non-core audience off-guard, but because she is comparable with the other heavy hitters already established in the MCU also.
That is not just my opinion, It's Marvel.com's. Here are some comparisons:
Captain Marvel
Thor
Hulk
Iron Man
Thanos
As powerful as he is, Thanos confronted the Avengers, Guardians and Wakanka with an army and was still a Stormbreaker strike to the head from defeat. In my opinion, CM will be the tipping point in Endgame. And the funny thing is I do not think Thanos will ever see her coming, lol.
I may add all the reference links later. Or anyone can visit Marvel.com, select a character and choose the
IN COMICS FULL REPORT for the characters' comparisons I embedded above.
