He was great freinds with GE-5 or gess, until, she was thrown into the incinerator with azul, azul could run, and tried to save gess, but he was too late, gess was already in the incinerator. All he heard was gess screaming for him to run, crackling and roaring of fires consuming gess's body. and that wretched song.... mr blue sky, looping over and over

and when he hears that song, that rage he had, the rage at the people who decided to murder his friend and attempted to murder him. he will kill anyone, who isnt his friends in his wake.
