Storm is a notable X-Men character who has always been overlooked in live-action adaptations. From what she was given in the four X-Men films she starred in, she's a hero anyone can look up to. Assisting Nightcrawler (Alan Cumming) in X2 and stepping up in Professor X's (Patrick Stewart) shoes at the end of X-Men: The Last Stand was evidence enough that she's a figure worth exploring. However, there still needed to be more pivotal moments in the series for Halle Berry and her character. And there almost was one, but Berry got cheated out of showing off just how impactful her character could be.
