Have a wiki while I work on some specifics.

BASIC CURRENT-DAY SCENARIO:
Once upon a time, Liquid Snake was sure he was invincible. This turned out to be false, and upon his death he was essentially butchered for his body parts. Or one body part, anyway. However, his spirit rather tenaciously clung to that arm, causing trouble for Mr. Ocelot with his attempts at possession. Or, at least, he'd tried to.
Turns out Revolver Ocelot had been working on, well, that exact sort of thing. Liquid's attempts at possession didn't exactly go so well when the man was acting like it was happening without him anyway. When Ocelot no longer needed that particular arm, or that particular spirit, thanks to his a-plus double-crossing skills, Liquid found himself ejected from the man's body while it still acted like he was there. Unwilling to just hang around and watch, he headed off for many years, doing normal ghostly things such as getting into concerts for free and watching naked people.
But somewhere, somehow, there was a nefarious lab, with nefarious scientists, doing nefarious things. And in this nefarious lab was a secret project: another set of clones, among them an exact copy of Liquid Snake himself, fully grown and ready to... well, that's classified. But word got out to the shirtless ghost, and he had to see what was going on for himself. There were still quite a few kinks to be worked out, of course. The body couldn't really do much on its own, its brain not really possessing much of... whatever it was that it needed. And that's where Liquid came in.
Opportunity knocked, and Liquid was home.
