R.A.M is from a futurist and cyberpunk dimension , he is a interdimensional warrior because his world is in constant war. And he dropped in the actual dimensions by a gadget made in the Dunshot enterprises (the company responsible for the war). To hide his identity, changed his white spotted coat to a black-ish with purple color and always carries a black bandada to hide himself plus he changed his name (Kai) to "R.A.M". his personality can vary depending on the situation and how the other person reacts and treats him- he can get to be very kind and even protective with people he loves and care about but if someone attacks him or any of his friends he will attack (or in some cases even kill) and he can get pretty cold, serious and sarcastic towards someone he hates or feel uncomfortable with.
