9. She-Hulk
She-Hulk is the alter-ego of Jessica Walters, Bruce Banner's cousin. She received an emergency blood transfusion from Banner that causes her to turn into She-Hulk, a milder version of the big green rage monster. When transformed, Walters largely retains her personality, and has been a member of several of Marvel's teams: The Avengers, Fantastic Four, Heroes for Hire, the Defenders, Fantastic Force, and S.H.I.E.L.D. She's also a skilled lawyer and has acted as legal counsel to numerous superheroes. She-Hulk was almost featured in a film of her own in the '90s (after a couple TV pilots failed to get off the ground), but the project never materialized. She could be an interesting addition to the Marvel universe, especially once the studio moves forward with more Hulk-centric projects. She may not be fit for her own film, and a One Shot would be an interesting way to introduce her to the world. Perhaps the short could focus on her in the courtroom? Or act as an origin story, focusing mainly on Jessica Walters and then ending with the blood transfusion and subsequent transformation.
