I'm sorry but I'm one of the fans that cares. I do not like this casting, I would rather have a 40 year old pretending to be teenager. I guess Zendaya probably fit the party girl best or maybe just because shes a "Disney Princess" (contract Disney singer who has their own Disney show).
I consider him a Marvel character, he was an Invader (but I don't know if he was an Avenger or appeared in an issue), he was in Defenders, he was involved with FF, he was a member of the X-Men, he was in The Illuminati, and I think he once was apart of Heroes for Hire. Only thing he wasn't apart of was SHIELD.
