Is there another character like Kingpin who could fill the same role? The role I envision is someone pulling the strings like an organized crime boss would. His goons run across several heroes in origin stories. The heroes figure out these goons are not the boss and they vow to go after the leader. Maybe the leader could be tied to AIM or be a head of HYDRA sowing chaos. The the heroes end up together to take on several goons and the leader in the team-up film. I think this is a similar formula to how a Masters of Evil film would develop with minor differences.
