You were in a lab all your life.You got made there basically.You were a hybrid,a dangerous one aswell.The Scientists did hard experiments on you.It wasnt fun,it was torture

The lab you were in was under attack by TF141.You got bored and decided to have some fun since your door was left open.You killed so many Scientists it was impossible to count.You put on 'cupid' and started dancing to it while the dead bodys were next to you.

Gaz: "is this the dangerous hybrid..?" Ghost: "uhmmm.."
