Let's see.

Black Widow: Supporting character. Dead in MCU by suicide.

Peggy Carter: Supporting character. Dead in MCU by old age.

Gamora: Ensemble/supporting-ish character. Dead in MCU after her adoptive father threw her off a cliff, timeline shenanigans means the one from the past shouldn't exist otherwise it breaks things

Okoya: Minor supporting character to a film whose lead actor died IRL of cancer.

Valkyrie: Supporting character nothing like any version of the comics. Alive but with an alcohol level so high even RDJr never came that close.

Wasp: Supporting character. Probably going to get cancelled because Lily spoke out against masks mandates or the aggro truckers were getting

Scarlet Witch: Supporting character. Portrayed so badly in her solo show even normies are calling out the fact she mind controlled an entire town

Nebula: A literal supporting character for another supporting character whose entire background is "I failed so much I'm mostly robot now. Also I killed my past self so surely I should be dead, right?"

Carl Manvers: Should have been played by Nova in Endgame. Gets called "an assist" and has one of the stupidest scenes in the entire MCU because of how overpowered she is nobody could even come close to providing her support anyway.

Hmm, yes. Much stronk. Many indepenis.

Also worth noting that: Black Widow [ninja with guns], Peggy [Brit with guns], Gamora [ninja with guns], Okoya [ninja with "magic" spear"], Valkyrie [actual magic sword], Wasp [same suit as the main character but with guns, and wings], Nebula [another ninja with swords] are all the same boring character archetype.

They are either a copy of the main character with more bells and whistles put on, or a generic "ninja with guns" grrrl-powah featherweight that should be knocked down by even a stronk wind.
