For all the good things the X-Men movies managed, they still held back on a lot, like some characters' powers.

Which hero from the movies got dealt the worst hand, considering how powerful they are in the comics? For me its Storm, a god-like character that they make basically just push things around with the wind.

i think you have it down with storm, she was underutilized

"Do you know what happens to a toad when it's struck by lightning?"

Definitely Storm along with Rogue and Darwin.
