Black Widow/Natasha Romanoff

Black Widow is one of the world's most talented agents and assassins and one of the founders of the Avengers. Originally a spy for the Soviet Union's foreign intelligence agency, the KGB, she later became an employee of S.H.I.E.L.D., a global counterterrorism organization. First of all, she possesses a close combat ability that is not inferior to Clint Barton. And yet, Black Widow is also a super spy. She can get information from anyone in any way she wants and the victim remains ignorant.

Black Widow possesses high martial arts skills and is equipped with Widow's Bite, Black Widow became one of SHIELD's best agents. Natasha's physical strength is enhanced to the limit of human maximum potential. Natasha's body is strengthened to withstand much greater bodily damage than usual, she has enough strength to withstand falls from above in combat. In addition, Natasha's agility, flexibility, balance, and dexterity are increased to perfection. Her reaction speed is much faster than the average human's, as well as easily spotting and even dodging bullets at close range. In fact, Natasha was also injected with a super-soldier serum, which is similar to the serum that Captain America was injected with. This explains Black Widow's super slow aging, and also explains her superior intellectual, physical, and other great skills.
