According to the Deathbringer, the Reapers were warriors who caused utter destruction. However, their prowess caused them to be feared even among their own, leading to isolation and bringing them towards madness. They found each other and resolved to use their powers to destroy war within the universe by eliminating violent races and removing things worth fighting over. They laid waste to the strategically important planet, Mumu-Obscura, to remove it from the equation and spare needless future conflict. When Decepticon Sixshot arrived on Mumu-Obscura to locate the his 'friends', the Terrorcons, the Reapers attacked him as a test of his abilities. The Deathbringer offered Sixshot a place among them if he would kill the Terrorcons, but Sixshot was still unable to sever his connections to the Decepticons. The Reapers accepted his decision and said that they would cross paths with him again, hoping that he would later be able to accept their offer. Spotlight: Sixshot
