The '''Dark Signers''' are were a mysterious group of duelistsDuelists resurrected and in the service of the [[Earthbound Immortals]], who serve served as antagonists the evil counterparts to the [[Signers]] and were the primary antagonists for the [[Dark Signers (arc)|second arc ]] of ''[[Yu-Gi-Oh! 5D's]]''.

==Background==When a person diesdied, he or she is was given a chance to live by becoming a Dark Signer at the time of their death. If they display displayed a great will to live or a reason for revenge, an [[Earthbound Immortals|Earthbound Immortal]] may spare them (provided they agree willingly, whether or not they remember doing so after being brought back), turning them into a the Dark Signer Signers in the process. However due to this phenomenon which derives from the Underworld itself, there's no way to revert As the transformation. As a Dark SignerSigners, those individuals are were given a great power and a great lust for revenge. With all All of the Dark Signers, with the exception of CarlyRoman and Rex, they hold held some form a of grudge against (or connection to, in the case of [[Devack]] and [[Carly Carmine|Carly]]) a Signer, which would provide an another answer to why the Earthbound Immortals chose them. They are Due to this phenomenon which derived from the Netherworld itself, there was no way to revert the transformation or revert to their former selves, and were said to be no longer of the living world . If they turned over a new leaf in a Duel, the Earthbound Immortal would take over them and incapable continue the match (however Akiza noted, their control can potentially be broken if the Earthbound Immortal is destroyed without getting rid of reverting to their former selvesthe person's Life Points).

Thus because of this distinctive group of individuals already had died once, it is seen that once they have been defeated in their own Shadow Duel or Shadow Turbo Duel for that matter, their departure from this world would be completely different. As instead of simply dying like a normal human being, they instead would wither until they became dust when they were sent into the Netherworld. They are were capable of using a distinctive new type of monsters known as [[Dark Synchro MonstersMonster]] s which are were black lined. Their [[Signature Cardsignature card]] are the "[[Earthbound ImmortalsImmortal]]s", along with the use of Field Spell cards in order to maintain the effects of these powerful beasts in a Duel.There were only five Dark Signers at any given time, each one possessed by a different geoglyph. In the anime present altered time-line, a total of seven awakened, due to the fall of others. Devack was 'succeeded' by Greiger and Rex was revived after his Duel with Roman. Dark Signers are shown to have a red [[Criminal mark]]-esque patterns on their face and black sclerae. ==Members=={| class="wikitable"|-!

Later, right after Akiza’s Duel against Misty concludes, before the Signers were able to seal the last Tower, the King of the Netherworld appeared from the Original Ener-D Reactor, and was moving toward New Domino City. At that time Rex who had acquired the powers of a Signer with Roman's arm, revealed to be the last of the Dark Signers. As the dark mark of the Condor appeared on his back, it revealed his Dark Signer nature and gave him supernatural powers, he declared that a [[Shadow Turbo Duel]] would be held within the Condor geoglyph as a ritual to welcome the [[King of the Netherworld]]. Therefore, Rex faced off against Yusei, Jack, and Crow in one final Shadow Turbo Duel. The Duel raged fiercely upon them and Rex. Though both Jack and Crow were unable to continue due to [[Earthbound Immortal Wiraqocha Rasca|Wiraqocha Rasca's]] deadly effect, Yusei managed to win with their help. [[File:DS.jpg|thumb|Four of the Dark Signers returning to life]] After the King of the Netherworld was finally destroyed by the combined power of Yusei, Majestic Star Dragon, and the Crimson Dragon, all of the other Dark Signers were returned to life, leaving only the Goodwin brothers to pass on to the afterlife. As for the former Dark Signers, it's unknown if the others do or don't have recollection of ever being one, judging by Carly's statement and Kalin's current state. (Although it appears that Kalin and Greiger are the only ones with any recollection of their crimes as Dark Signers).  Order of reappearance:*[[Misty]]: It is shown that she and Akiza become close friends, and are now pen pals. She reappeared in many advertisements in Season 2, but had yet to make a physical appearance.*[[Carly]]: She appeared by throwing off her old man disguise a short while after Akiza mentions Misty. She continued to be friends with everyone, normally helping [[Jack]] out of any tight spots. It is unknown if Carly was still friends with [[Misty]].*[[Kalin]]: He went on a trip and ended up in [[Crash Town]]. His "new life" didn't seem to be as successful as the others; he wore a ragged black cape, is physically exhausted, and has lost all emotion, joining a large group of Duelists that Dueled against "[[Malcolm]]´s" group, with lifelong slavery as the loser's penalty (Even then, he is still admired by the kids of the town.). He Dueled Yusei one more time, so that he can leave the world of Dueling behind him (It is revealed, that he kept his Dark Signer memories, and wanted to die for those actions). However, after a series of events, Kalin's will to live changed, making sure that the town and its inhabitants live peacefully from now on.*[[Greiger]]: He returned to his hometown, where he reunited with [[Annie (Greiger's sister)|Annie]] and [[Max]]. Since then, his family moved to [[Nazca Lines|Nazca]] where they build a shrine to pacify the [[Earthbound Immortal]]s and spent the rest of the series tending to it. He also kept his memories as a Dark Signer, and wanted to repent for that crime.{{clear}} In an information file that [[Z-one]] reads in [[Yu-Gi-Oh! 5D's - Episode 149|Episode 149]], in the "original" timeline before he and [[Iliaster]] caused the [[Zero Reverse]] to split the cities, there were only five Earthbound Immortals that fought the Signers - Uru, Ccapac Apu, Cusillu, Aslla Piscu, and Ccarayhua. This would seem to suggest that Rex and Greiger did not originally become Dark Signers, and that it was Z-one's interference with the timeline that caused them to become such. ==PowersAbilities==

While brainwashed, the victim's Duels become became Shadow Duels and their Deck is was changed to one more fitting to a Dark Signer. In the English version the brainwashed person was known as a '''[[Shadow Drones|Shadow Drone]]''', while in the Japanese they refered to themselves as actual Dark Signers.

The spell is was lifted when the victim loses lost a Duel. At this point the spider is was ejected from their body and erupts in erupted into a powder. The victim's Deck is was then restored to normal and they have had no memory of what happened while they were brainwashed.

People who become became real Dark Signers are were believed to be brainwashed. Their motives are were fueled by revenge. While some accept accepted it to be their own free will, in Carly's her actions it appeared that when their hatred motives are not always as she wishes and appears as though she is no longer pursued, then the Dark Signer will become possessedby their corresponding [[Earthbound Immortal]]. In This happened in [[Yu-Gi-Oh! 5D's - Episode 053Greiger]], [[Carly Carmine|episode 53Carly]], and [[Earthbound Immortal Chacu ChallhuaMisty Tredwell|Chacu ChallhuaMisty's]] openly possessed Greiger after he no longer wanted Duels, forcing them to continue fightingagainst their will.

When a Dark Signer engages engaged in a Duel, the arena is was surrounded by a forcefield force field of dark fire, taking the shape of the Dark Signer's respected geoglyph and becomes became a Shadow Duel(However it has been proven that they can choose whether or not to make the geoglyph appear. This is evidenced by Misty in episode 60, whom Duels Akiza, but the flames do not appear until she makes it). When a brainwashed Dark Signer servant engages engaged in a Duel, the arena is was instead surrounded by a purple glow.

During a Shadow Duel, players suffer suffered real damage when attacked by monsters. The blasts from the attacks are fatal and often cause caused damage to the surroundings. Also, according to [[Divine (Character)|DivineSayer]] during his duel Duel with [[Carly NagisaCarmine]] in episode 39, the effects from a [[Shadow Duel]] are more powerful and deadlier than that of [[Psychic Duelist|Psychic Dueling]].
