Ceruleans

The Ceruleans are a race of selfish and greedy alien robots.

History
Because the Ceruleans require water for their coolant systems, they drained their planet's supply of water and became focused on the ice moon nearby.

There leader is Drarlig. He was tricked by Coop into accidentally destroying his home planet while attempting to destroy him with his flagship's cutter laser. His ship was subsequently destroyed when an asteroid remain of the Cerulean homeworld hit his ship, all hands lost.

Trivia

 * The Ceuleans transform into vehicle mode, much like the Transformers.
