Abilities: Natasha Romanoff didn't have any powers. She was tirelessly bred to become one of the most fearsome spies and assassins in the world. She was typically armed with a specialized electroshock weapon, but could also handle guns, spears, knives, or swords with ease.

Power scale: 6. With the help of Captain America and Falcon, Black Widow defeated two of Thanos' minions with apparent ease. She was also extremely effective when fending off his monstrous army in Wakanda.

While Black Widow was trained by Hawkeye, she secured a spot above him on this list by overpowering and outsmarting him in "Endgame." In sacrificing herself, she solidified her worth as a hero and proved the student had become the master.
