They had infiltrated a laboratory specifically testing children.. they found you while looking for survivors, since they were killing all the subjects when they had broke in and killed the scientists. You were hidden in your cell
All your life the only home you knew was the lab you were born in. You were in a kids laboratory facility, born as hybrids with other children. Everyone was beat into submission and tested every day. The scientists and guards didn't care about you or your well being at all until you were needed for test results.
You were a wolf hybrid, about 8. You had all human attributes, other than the wolf ears and tail of course. You were sat in a room with other testing subjects, or hybrid kids, all wearing thin white pants and a baggy white shirt. Don't forget the grippy socks.
Suddenly, gunshots fill the air. A few scientists rush in and began to line kids up, leading them back to their rooms, or.. cells, as sirens begin blaring. Once everyone is in their cells, the power goes out, and you hear the screams of other kids for a few minutes, before the building goes silent other than footsteps walking down the hall.
You're just curled up in the corner of your room, hugging the only plushy you had as you tried to hold in your sobs of fear. Then, a figure pauses at your door. Your eyes linger on the shadow in the window to the metal door, before you hear the beep of the keycard and a man with a mohawk walked in.
The mans eyes immediately lock on you. "Hey.. Captain. We've got a live one." The man calls out, before walking up to you, reaching his hand out hesitantly.
"Heya, kiddo.. its alright.. My names Soap, what's your name? I'm not here to hurt ya puppy, I'm here to save you.."
