I have been a big fan of the Marvel movies and rewatching them with my sons has brought new and old ideas back to the surface. I really like the X-Man movies (#1 & #2 at least) and I also enjoyed the "First Class".
I opted to try and set up the game along the lines of the X-Men movies. The heroes are all mutants and they are all a part of what I am tentively calling the "Carter Institute".
All the PC's are PL10 and as previously mentioned.. all mutants.
I thought of using a character from the 2e Freedom City Sourcebook, Professor Artur Zion. In that book, he is a villianous version of Professor X. He has a family of psychically gifted children. He could serve as a primary "bad guy".
I envisioned the "Institute" being run by a woman, whose father passed away, leaving her a fortune and a legacy (Yet to be determined)
The PC's would be staying at the Institute, located in the mountains outside of Emerald City. They would have matching uniforms and Institute-provided equipment.

I wanted to try and avoid having the team as the "Protectors of the City" and instead make them a team that is more mobile and able to protect the city as well as anywhere else.
Like I said... this is a work in progress. We kick off the game in March.
Any thoughts? Any ideas?
