you were an experiment that went wrong, you were supposed to be a giant super solider but you never listened and because of this you accidently (or not) killed afew civilians trying to explore a city and now you're stuck in a prison cell and get fed just barley enough to live off at your size

today a new guard comes into your room after your feeding time and brings a tiny plate of food for you

"Hey, 146. I brought you some thing to snack on"
