I like the plot concept. It's got a defined purpose, and some defined sides. I do think that including Sebastian Shaw might be overkill for the villains. Shaw's power is too flexible and powerful I think for the concept you have presented. Part of the reason I say this is also due to Starlequin's interest in playing an OC that has some form of power absorption. I think that will make up for Shaw's combat dynamic. Exchanging Shaw for Magneto would even the battlefield a bit more, and create more of a fluid dynamic between the good guys and bad guys as they're not out to completely destroy each other. They merely disagree - violently.<br/><br/>Shaw is more of an "I don't care what happens to anyone as long as I get what I want" type. Where as Magneto has a slightly less destructive goal of world domination in mind. Just my two cents.
