Adversary has only been in like, 3 stories, and in 2/3 of them, Forge essentially solos him. Adversary is a minor demon, he's not even a real god.
Claremont had Storm taking down Brood ships with cosmic lightning back in the 80's, and she didn't need 5 issues to charge up. Even Hudlin had Storm knocking space ships out with a thought.
Coates can't write competitively in the comics medium. I hope they don't saddle Ororo with him on her solo. Marauders is not Storm at her best, but I will say it's more entertaining that what Coates manages. Let Hickman do his thing on Storm's Giant Size issue and then we can reassess the situation.
