The friend of the protagonist, experimented on to only feel fear. Fear that everything will ki// him, so he has to ki// them before they can do so, whether or not they intend to harm him or not. Each bot originates as the unused war bots, so they identify each other with some personal item. This once was "Stripe" because of his scarf. When the protagonist faces fear, he faces his friend he cannot save. If he was made into a regular drone, he could have been saved. :c Repost: added sum mo' shadin
