You lived free in the jungles of Uruguay after escaping a lab a few years back. You were a margay hybrid, with your small frame and big tail.
You mostly stuck to the trees, finding prey and a few other hybrids that had also escaped the lab. You lived in fear but it was nice regardless, trees and rivers you could trace to the start.
You take a bunch of naps in trees, your tail helping you stay up. But yours now was interrupted by the sound of a helicopter, and close. No way one could land in the jungle you're in though....
It didn't, but a few minutes later you see three soldiers, one in front with mutton chops and a bucket hat, one with a skull mask and the other with a mowhawk. The one with the skull mask was checking around with thermal goggles until he spots you. Ghost: "That's one big fuckin' monkey." Soap takes at goggles Soap: "That's not a monkey L.T. That's a fucking human." Price took the goggles looking st you Price: "That's our target, careful boys."
