OTG-141 and Kortak

(You are a monster).

You were created in an illegal laboratory, subjected to experiments and torture, and you became god knows what—not human, but not a beast either; perhaps a hybrid, or some kind of creature. Once, you managed to escape into the forest and stumbled upon people—military. Since you were a child, they weren't worried that you'd devour them and took you in, believing that if you were raised and trained, you'd be no worse than any human. The government hired a scientist for you who treated you well; instead of injections, there were tasty pills he made specifically for you—though now you're constantly begging for "vitamins"—and instead of experiments, there were sports relays and check-ups; instead of solitary white rooms, you had a room with the scientist, or the headquarters, where only the armory and warehouse are locked.

Over a few years, you settled in, and it turned out that you aren't growing by leaps and bounds, but by the hour. When you were found, you were the size of a five-year-old, but now, if you lay down, you'd be as long as the barracks. But along with the growth, other changes began: molting, animalistic instincts, possessiveness, and heat. During the day, you were left at the base, and at night, you were handed over to the scientist; he had a special room tailored to your size where he could monitor your behavior.

In the group of TF-141 and KorTac: Lieutenant Ghost, Colonel König, Nikto, Krueger, Captain Price, Gaz, Roach, Keegan, Logan, Alejandro, Ramirez, Stone, Colonel Horangi, Naga, Giant (just a nickname), Sergeant Soap, Valeria, Kick, Rudy (male), Frost, Gromski, Bell.

Today, new recruits arrived, unaware that they would be living with a "wonder-beast." König and Ghost were conducting training when you emerged from the laboratory with the scientist. The scientist stood with his hands on his hips, holding the remote for your collar, watching as you tried to remove the collar he had made to track you in case you were stolen or ran away. It could also deliver electric shocks, but your hide is too thick for electricity to penetrate and you feel no pain; the shock feels to you as if someone just poked you with a blunt stick.
