Earthbound Immortal " Earthbound Immortal " , known as " Earthbound God " ( " Jibakushin " ) in Japan , is a sub - archetype of the " Earthbound " archetype used by the Dark Signer s in the " Yu - Gi - Oh ! 5D ' s " anime , composed of 7 Level 10 DARK monsters with various Type s . " Earthbound Immortals " are based on the . 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 . They are among the largest monsters seen in the anime ; dwarfing humans and being comparable to massive buildings in size . Anime . The Earthbound Immortals are the evil incarnations that were sealed away in the underworld by the Crimson Dragon and its servants 5000 years before the events of " Yu - Gi - Oh ! 5D ' s " . These malicious entities were released as a result of the Zero Reverse incident . They serve as the ace monsters of the Dark Signer s , possessing them to serve as gatekeepers of Old Ener - D , which serves as the entrance of the underworld . Playing style . 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 " " . 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 . Another strategy is to use " Mausoleum of the Emperor " ( protected by " Field Barrier " ) with " Prohibition " blocking Spell and Trap removal cards such as " Mystical Space Typhoon " , " Twin Twisters " , and " Dust Tornado " . This can also be supplemented by " Dark Bribe " , " Magic Jammer " , " Seven Tools of the Bandit " , " Ultimate Providence " , and " Earthbound Wave " , and " Trap Stun " in more desperate conditions . The " Earthbound Immortal " monsters can all be Summoned easily , due to having no restrictions on Special Summoning them ( except the field - unique condition ) . Weaknesses . 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 .
