Voltron Wiki

The Robeasts are the monsters of the Drule Empire that are sent to fight the two Voltrons of the Galaxy Alliance.


The robeasts from planet Doom were created through superscience and/or Haggar's magic, some of them simply being giant robots piloted by Doom soldiers or fully automated.

The Drule robeasts that battled the Explorer were uniformly technology based.

In Golion, they are referred to as Deathblack Beastmen and later Mechablack Beastmen. Dairugger XV called them Combat Machines.

In Voltron: Legendary Defender, they are simply called beasts and are infused with quintessence and a soul of a sapient being as a base, be it a slave like Myzax, a simple reptile, or one of the Empire's own commanders such as Prorok. The Robeasts are created specifically to battle Voltron, and the process of creation usually entails painfully transferring the being's very essence into a larger artificial body, leaving the original corpse behind. In the second season, they are referred to as robeasts again.

Known Robeasts

Planet Doom Robeasts (Wave 1)

The Robeasts from planet Doom sent to battle the Voltron Lion Force are reared in gladiatorial combat and are humanoid monsters created through a combination of superscience and Haggar's magic, usually from prisoners of war, though some of them are volunteers while others are simply giant robots piloted by Doom soldiers.

Planet Drule Robeasts (Wave 2)

In Voltron Force, a new series of Robeasts are produced by infusing Apex predators from various planets with Haggarium. The resulting creatures are biomechanical beasts with the Haggarium enabling them to normally weaken Voltron with special abilities augmenting their natural talents.

Voltron: Legendary Defender Robeasts

In Voltron: Legendary Defender, the Robeasts were simply called beasts by Zarkon and the Galra. However, the term "Robeast" is later coined by Hunk in season two of the show. In addition of three Robeasts that were mechanized robots infused and given life by the quintessence of a being's soul implanted into the beast by Haggar's dark magic, there's also a Robeast created by Branko. Excluding Branko's Robeast, only three Robeasts have been seen so far in Legendary Defender.
