Darth Horus

Darth Horus was the apprentice of Palpatine after the death of Anakin Skywalker. A clone of an unknown individual, Horus used the unique Blast Saber, a lightsaber modified to shoot blaster bolts. Horus had been created as a perfect Sith Lord, genetically modified with superhuman strength and endurance. Though in-progress during Palpatine's rule, Horus did not emerge until Palpatine passes his spirit to a clone body. Horus was outfitted with a powerful enviromental suit, a white chestplate with several tubes and black shoulderpads. Horus looked out of a red-tinged transparent sphereical helmet. In reality, Horus's armor was grafted to his flesh, unable to remove without destroying his own central nervous system. Though not self-aware, Horus eventually grew his own intelligence and a lust for power. Horus attempted to murder Palpatine and become a new emperor, and while Palpatine survived, he was damaged greatly, which hindered his resistance in his eventual final defeat. Palpatine summoned a battalion of stormtroopers, who blasted Horus several times in the face, killing him.
