Or it could be Marvel using Storm as the token black character. Storm is poplar but no where near that of the people she's around. Do I think that's fair? Absolutely not because imo out of all the "colored" characters Storm is the most interesting imo.
Basically don't get your hopes up. Try and learn the difference between Marvel actually rooting for Storm or them just using her as a well known Token.
As a side note upon closer looking at the image it may be Avengers related which could be good for Storm. A team that takes on more powerful threats could mean Storm can do more wild feats!
