To further enhance the presence of powerful female heroes in to their movie universe, Marvel could bring in one who appeared in the original Infinity Gauntlet story arc: She-Hulk. She-Hulk is Jennifer Walters and she is essentially a female version of Hulk, as the name would suggest. Walters gained her powers after being shot my some gangsters when her cousin, Bruce Banner (the aforementioned Hulk who already exists as a prominent character in the Marvel Cinematic Universe), saved her life by desperately giving her a blood transfusion using his own gamma-infused blood. This is a sub-plot that could easily be brought up - even in passing - in the Marvel Cinematic Universe, as an easy way of introducing the character. As She-Hulk, Walters' powers are very similar to those of her powerful cousin she possesses great superhuman strength, endurance and healing abilities but she usually retains her intelligence after the transformation and can transform at will, rather than by having to get angry, and the level of her strength is somewhat watered down in comparison to the green goliath. She-Hulk has been a key member of some of Marvel's most prominent heroic teams such as the Avengers, the Defenders, the Lady Liberators and Heroes For Hire, amongst others and her brute strength would be a welcome addition to the MCU's Avengers roster (and a potential face-to-face meeting with fellow green female Gamora would bring a nice moment of comedic relief).
