One hundred thousand years ago, Kup was visiting planet Dredd, when he was kidnapped by Orbs and forced to work in their death crystal mines. One day, Kup and the other slaves were attacked by some bat-like aliens, and a fellow slave explained that the aliens were fleeing from the monstrous Chaos. Seconds later, Chaos caused an earthquake that killed the entire group of slaves, except Kup, who ran off and found dozens of imprisoned robots in the caves. As he was preparing to free them, Chaos appeared, and Kup ran away in fear and left the slaves behind. Kup never forgave himself for this, and refused to recount this story to anyone until he discovered that the Decepticons had discovered the dangerous death crystals.
