There can be multiple heroes sponsored by the Leaguers. I'm sure not all of them will be taken anyway because player's don't exactly have to give them a similar power set to the sponsor. I also just edited in the Powers & Weaknesses parts of the CS template. Can't believe I forgot them initially. 

My guy just has Superman as a sponsor cause he's also a humanoid alien who crash landed on Earth, but instead of Smallville it was in Metropolis.
