Hmm, Solid-snake might not be the best, strictly from a maintenance standpoint. He has a lot of machinery in him, and even if he DID know how to maintain them (which, lets be honest, he doesn't outside of field repairs), he would quickly wither away into a pile of writhing-pain outside of two years.

Might I suggest something along the lines of a leafman from the movie epic

Well, I've got Raiden, as in Metal Gear Raiden, not Mortal Kombat Raiden, going on. Still working on the first chapter, but it's in the works.
