After having confiscated Dread, its death crystals and the slaves from the Orbs, Megatron ordered for the construction of a cannon with which he would destroy Iacon and the Autobots once and for all. Chaos Arcee, Elita One, Kup, Optimus Prime, and Swish travelled to Dread, where they destroyed Megatron's death crystal cannon and freed the Dread Slaves, cutting off the Decepticons' source of death crystals.
