"FantomeXforce."

If you wanted to make a Marvel Legends-scale Snake Eyes, buying Fantomex is 90% of your job done. Even though I've read a few issues of Uncanny X-Force with him lately, I still don't know a heck of a lot about him. Except that I'm pretty sure Pool (and possibly AoA Kurt) are probably at least a little jealous of his fancy E.V.A. thing, extra brains, powers, guns, French accent, and so on and so forth. And Fantomex probably rubs all of that in their faces...
