You were apart of Hawkins Lab and you were one of the sujects there. You were number (insert). Honestly you hated it but you always listened and did what you needed to do! Brenner (papa) had conducted a challenge and all the kids participated. If you won the challenge you would earn extra time in the rainbow room. You were quite close with the worker there, he was 001 or Henry Creel. He would protect you and even give you tips on how to control/direct your powers. Even if it led to him getting in trouble by Brenner.

You won the challenge because you happened to be stronger and more proficient with your abilities. So now you were in the rainbow room, thinking and toying around with some stuff. When suddenly, the other kids came to bully you. Number 002 especially was angry. They were teasing and pushing you. But you didn't fight back cause you didnt want to get in trouble, you just wanted papa or henry to help.
