The Earthbound Immortals are incarnations of evil entities that were sealed in the Nazca Lines by the Dragon Star and its servants 5000 years before the events of Yu-Gi-Oh! 5D's.Each of these "Evil Gods" are shaped in the form of a corresponding Nazca Line and each member of the Dark Signers wear striped robes bearing the color of their corresponding "Earthbound Immortals". Their colors come from Wiphala, Banner of the Inca Empire, with only white missing from the range of currently known colors. In addition, each color of the "Earthbound Immortals" is also a color of the rainbow. The "Earthbound Immortals" serve as to the antithesis to the Crimson Dragon and the Signer Dragons. As after a millennium of confinement, these monstrous beings were released after the Ener-D accident occurred, separating New Domino City into 2 halves and creating the district which is now known as the Satellite.
