Storm has been in the entire Marvel vs. Capcom series since this game. Although she wasn't in every game, she managed to stay in the roster for (Ultimate) Marvel vs. Capcom 3!
Back in Children of the Atom, she's a bit more humble in power compared to the exploits players have discovered with her in MvC2.
Two of her Special Moves uses wind to blow her opponent towards or away from her for. UMvC3 will recognize these as her Fair Wind and Foul Wind. Another meter-eating Special is her Flight. In this game, she can guard while flying.
Storm's only Super is the Lightning Storm. It actually stretches out a long distance all around her compared to UMvC3. She can also air dash in all eight directions, and slow her fall by holding Up.

In Storm's ending, Storm leaves Magneto to die with his exploding Avalon, as Magneto stubbornly refused to join the X-Men to protect humanity, rather than Magneto's plan to rule over it.
Ororo Monroe, a.k.a. Storm, one of the most powerful X-Men (or should I say X-Woman) helps her allies out by quickly taking out a Sentinel. She is then joined by a fellow X-Man, Forge, who is very thankful that he came to help out.
