MCU's Black Widow is the Mightiest Avenger

One unexpected result from my MCU (Marvel Cinematic Universe) re-watch is that now I can't wait to see the upcoming Black Widow movie that will be out next year. From Iron Man 2 to Avengers: Endgame, Natasha Romanoff gave it her all (including her life) to save the day. And what made her efforts so remarkable is that she had absolutely no powers or enhanced abilities but she was out there fighting mercenaries, aliens, Hydra, etc. as if she did.

Natasha is exceptionally skilled and can handle nearly any task or mission but there were times when even she was afraid such her having to run away from the Hulk on the Helicarrier in The Avengers movie but she didn't let that stop her from doing what she needed to do. I think what motivates her is a strong sense of duty and trying to overcome the guilt of her past.

To me the Black Widow is the Mightiest Avenger because not only did she save the world without any superpowers but also while striving to be a better person.
