Dread


 * Dredd is a planet near the current location of Cybertron..

Dredd is a rather unpleasant planet which possesses both hordes of slavers and the monstrous Chaos. As such, it is also the only planet on which death crystals can be mined.

It probably doesn't get much tourism.

Generation One cartoon continuity
While Optimus Prime and Megatron's crews were taking their stasis lock nap on the Ark, Kup found himself on Dredd, being chased by an Ick-Yak. During his misadventure, he was captured by the Orbs to mine death crystals for them. Managing to get away from his work detail, Kup fled into the tunnels, finding a group of imprisoned robot slaves. As he tried to rescue them, the monstrous Chaos appeared. Kup was so frightened he fled, leaving the other robots imprisoned. He was so ashamed he never told anyone about the incident.

One hundred thousand years later,the death crystals were discovered by the Decepticons. Megatron took Astrotrain and the Predacons to build a massive death crystal cannon. Optimus Prime led a group of Autobots to stop them.
