Voltron
Voltron is the giant robot created from the combination of all five Voltron Lions It has been ten thousand years since it was last formed, and its return is brought about when Shiro returns to Earth a year after his capture by the Galra Empire, drawing Keith, Lance, Hunk, and Pidge together to locate the Blue Lion and use it to find the Castle of Lions on Arus. They reawaken its sleeping inhabitants, Princess Allura and Coran, and these last living Alteans help locate the subsequent Lions to form Voltron and defend the universe against Zarkon's empire.

In the past, Voltron's said creation by King Alfor after a comet of trans-reality ore collided with Daibazaal during a time when planet Alfor held an alliance with the planet's ruler, Zarkon. King Alfor built the Voltron Lions from the Quintessence-infused ore of the comet and Zarkon became the Black Paladin to defend his home planet from the darkness escaping from the reality rift left at the comet's crash site. He was joined by Alfor, Trigel, Gyrgan, and Blaytz. Coran's grandfather built the Castle of Lions to house the Lions and Voltron was known as a heroic fighting force.

Once Zarkon and his wife, Honerva, became obsessed with the Quintessence found in the reality rift, the exposure damaging Honerva's health, Zarkon attempted to bring Honerva into the rift using Voltron so he could save her with the Quintessence and darkness within. His fellow Paladins were not aware of his trickery until it was too late. The overexposure seemed to kill both he and his wife when they recklessly left the safety of Voltron inside the rift.

But after Alfor held their funeral and destroyed the evacuated Daibazaal to erase the reality rift forever, Zarkon and Honerva awakened, changed and corrupted by their ordeal. Zarkon flew into a rage at Alfor and the Alteans for the loss of the rift, sparking a war and the beginnings of the Galra Empire. Zarkon desired to capture Voltron so he could use the robot's power to create another rift and obtain the purest Quintessence of infinite amount. This led King Alfor to put Allura and Coran in a deep sleep inside cryo-pods within the Castle of Lions and to scatter the Voltron Lions to hidden locations across the universe so they would not fall into Zarkon's hands. Alfor led Zarkon to believe the Lions were destroyed, and so Zarkon slew the king, his fellow Paladins, and destroyed Altea.
