No one has ever went out and purchased a storm comic book. I dont even know if she had her own solo series before. The fact is the popular characters even the ones in groups always get their own spinoff. If they can carry that on their own then they are established characters. If not, then they aren’t that popular. This is the reason Antman had lower expectations than all the other avengers movies. He was the least read character of all them. I know plenty of people who’ve read Thor, Hulk, Cap, and even some Ironman solos. But Storm? Always part of an ensemble. True she was one of my favorite X-men. But outside of Wolverine, I wasn’t interested in any of the other characters solo adventures. If they can’t carry a solo comic they probably can’t carry a solo trilogy of films. This is reason Gambit will likely flop. Nobody is checking for a solo Gambit adventure. He’s a cool Xman but boring on his own. Same goes for cyborg, as a teen titan? Flames. but as solo act?
theres a well of difference between gambit and cyborg. gambit has had multiple solos as well as team led books. and despite what people will try to tell you now, was one of the most popular marvel characters. the closest cyborg has had to popularity is the teen titans cartoon, and he was an admitted second banana to robin. i dontthinkit will be successful, but is due to the development side of the movie, not the character
