"Earthbound Immortal", known as "Earthbound God" (
They are among the largest monsters seen in the anime; dwarfing humans and being comparable to massive buildings in size.
The "Earthbound Immortals" are based on the Nazca Lines. Each of them are pictured rising from their corresponding Line and their form matches the being they represent, as well as their Type. The "Earthbound Immortals" also each have a color of the rainbow.
When they are Summoned in the anime (and some video games), a beating stone heart appears in the sky absorbing souls in the vicinity, followed by a flash of light revealing their full form. When the Dark Signer is defeated, the souls their "Earthbound Immortal" took for their Summon are returned.
In the anime, the "Earthbound Immortals" are evil incarnations that were sealed in the netherworld by the Crimson Dragon and the Signers 5000 years before the events of Yu-Gi-Oh! 5D's. They were released from their seals as a result of the Zero Reverse incident. They serve as the ace monsters of the Dark Signers, possessing them to serve as gatekeepers of Old Ener-D, which serves as the entrance to the netherworld.
Seven "Earthbound Immortals" exist, each possessing a rainbow color.
Jack Atlas managed to seal the strongest "Earthbound Immortal", Red Nova, into a card via Blazing Soul. By merging the Crimson Devil with his "Red Dragon Archfiend", Jack created "Red Nova Dragon". Also, an additional OCG-original evolved counterpart of "Red Nova Dragon" was eventually released: "Red Supernova Dragon".

The "Earthbound Immortal" monsters are very powerful and have effects that range from inflicting Effect Damage to your opponent while locking their Battle Phase ("Chacu Challhua"), to taking control of an opposing monster, as in the case of "Uru". Also, all of them can attack their opponent directly and cannot be targeted for attacks.
As powerful as they are, they have some drawbacks: there cannot be more than 1 "Earthbound Immortal" monster on the field at the same time, and they are all destroyed if there is no Field Spell Card active.
If "Hardened Armed Dragon" is Tributed to Tribute Summon an "Earthbound Immortal" monster, it prevents it from being destroyed by card effects (including its own). Alternately, "Earthbound Linewalker" can be used to protect "Earthbound Immortal" monsters. "March of the Monarchs" will also stop them being destroyed by their own effects, as will the effect of "Number 66: Master Key Beetle". In an emergency situation, "Skill Drain" can also prevent them from destroying themselves.
Their strategy basically relies on attacking directly and dealing huge damage every turn; if they are protected by cards like "Safe Zone" or "Mound of the Bound Creator", there are few ways of stopping them. "The Seal of Orichalcos" also works well in this Deck, as it can protect itself while boosting your monsters' ATK by 500. "Terraforming", and even "Ancient Fairy Dragon" if used carefully or alongside "Field Barrier"/"The Seal of Orichalcos", can assist in making sure you always have Field Spell(s). "Ancient Pixie Dragon" can also be included to increase draw power as this deck relies on Field Spells.
The "Earthbound Immortal" monsters can all be Summoned easily, due to having no restrictions on Special Summoning them (except the field-unique condition).
Because they depend on Field Spell Cards being on the field, cards like "Ancient Fairy Dragon", "Black Rose Dragon" and even "Mystical Space Typhoon", "Twin Twisters", etc. can cause "Earthbound Immortal" monsters to destroy themselves. Cards like "Field Barrier" or "Malefic Stardust Dragon" can be used to protect a Field Spell Card from being destroyed.
Cards that cause the Field Spell Card to leave the field without destroying it (such as "Shaddoll Dragon" and "Castel, the Skyblaster Musketeer") are still a threat even with "Field Barrier". This can cause additional problems, as "Field Barrier" prevents a new Field Spell Card being played while it is active.
