Duel Dragon " Duel Dragon " ( , " Dyueru Doragon " ) is a series of dragonic monsters used by several key characters in the " Yu - Gi - Oh ! 5D ' s " manga . They are said to be cards specifically designed for Turbo Duel rituals in ancient times . Six of the " Duel Dragons " shown are counterparts of the " Signer Dragons " from the anime , and play a similar role in the manga . The " Duel Dragon " cards are ancient cards , who are held by the Skeleton Knight and Rex Goodwin in the present . They possess a massive dark power , enough to control their own holders if they are unable to tame them . A man who holds a " Duel Dragon " becomes a Duel Priest , while a woman becomes a Duel Priestess . Etymology . In the Japanese version , the names of all " Duel Dragons " have the following composition : " ( Adjective 1 ) ( Adjective 2 ) Dragon - ( Name ) " with the adjectives and " Dragon " written in kanji and the name in katakana . Some have two adjectives , while some have only one ; all Level 8 " Duel Dragons " have two kanji characters for the adjective ( s ) , and all Level 10 " Duel Dragons " have three . The kanji of each dragon that is based on a " Signer Dragon " from the anime ends in " 竜 " , while the ones original to the manga end with " 龍 " . In English , the names of the " Duel Dragons " have the composition " ( Name ) ( Adjective ) ( Dragon ) " . Most of the Dragons which have anime counterparts keep the name of their anime counterparts with the addition of an adjective , such as " Stardust Spark Dragon " , the Duel Dragon counterpart of " Stardust Dragon " . Design . The majority of the series are Dragon Synchro Monster s ( the exceptions are " Power Tool Mecha Dragon " , which is a Machine monster , and " Dragonecro Nethersoul Dragon " , which is a Fusion Monster ) . " Duel Dragons " with " Signer Dragon " counterparts display markings that seem to evoke the Mark of the Dragon somewhere on their bodies . " Duel Dragons " distributed by Skeleton Knight , as well as Skeleton Knight ' s and Rex Goodwin ' s Dragons , do not possess these markings . Both " Power Tool Mecha Dragon " and " Ancient Pixie Dragon " , which resemble their anime counterparts , can be considered dark counterpart s due to their DARK Attribute s and alternate effects . The " Duel Dragons " which are " Signer Dragon " counterparts often have a darker color scheme than the original , though " Stardust Spark Dragon " and " Blackfeather Darkrage Dragon " only demonstrated this when being used by the Priest of Light and Dark Crow respectively . Jack ' s " Hot Red Dragon Archfiend " does not appear to exhibit a darker color scheme , but this is difficult to discern due to the natural color of the " Duel Dragon " . Both " Power Tool Mecha Dragon " and " Ancient Pixie Dragon " exhibited darker color schemes while Leo and Luna were possessed by their Dragons ' Shadow Miasma ; after both Dragons were purified by " Stardust Spark Dragon " , they assumed the same color scheme as their original counterparts . " Duel Dragons " originating from Skeleton Knight all have 3000 as ATK and / or DEF values . " Void Ogre Dragon " and " Beelze of the Diabolic Dragons " have both 3000 as ATK and DEF , while " Dragonecro Nethersoul Dragon " has 3000 ATK with 0 DEF . Upon evolving , these " Duel Dragons " increase their ATK to 4000 ; " Beelzeus of the Diabolic Dragons " also has 4000 DEF , and " Dragocytos Corrupted Nethersoul Dragon " has 2000 DEF . Rex Goodwin ' s " Ascension Sky Dragon " also possesses a 3000 value , with 3000 DEF ( its ATK is ? ) . Abilities . " Duel Dragons " possess a strong miasma which causes their owners ' personalities to become darker , or even takes over them . When this happened to Kalin , Jack angrily asked if his " Duel Dragon " had eaten his soul , suggesting that Kalin had failed to control the dragon and was instead being controlled . The signs of the strength of the bond with a " Duel Dragon " have many stages ; those who have not gained dominion over the dragon properly often have blank eyes and a progressively darker personality , often emitting Shadow Miasma . Further succumbing to the " Duel Dragon " can lead to the skin of the face cracking and / or the whites of the eyes turning black , though all of these symptoms can be removed when purified . They also appear to have more occult powers ; When attacking Yusei , Leo ' s dragon showed him memories from Leo himself , while when Sect got mad at the Skull Flame s , his " Duel Dragon " card ' s miasma instantly caused them to fall on the ground unconscious . Furthermore , Rex Goodwin was able to pass memories of Akiza ' s past life directly to her mind by just making her have contact with a " Duel Dragon " card . " Stardust Spark Dragon " was able to show Yusei Fudo its " own " memories when he engaged in a One - Shot Run against it . However , the negative influences can be removed when a " Duel Dragon " is purified by another dragon . The only way to sever the link between a " Duel Dragon " and its holder is in a Duel . It usually happens when another " Duel Dragon " destroys the corrupted dragon , which is first demonstrated when Jack ' s " Hot Red Dragon Archfiend " clashed with Kalin ' s " Void Ogre Dragon " . Kalin ' s Shadow Miasma was removed , and he returned to his original personality . Yusei Fudo ' s " Stardust Spark Dragon " later destroyed both " Power Tool Mecha Dragon " and " Ancient Pixie Dragon " , freeing first Leo , and then Luna . Yusei would theorize that destroying " Beelze of the Diabolic Dragons " with " Stardust " would free Sect Injuin " from the " Duel Dragon " , which was later proven to be true when he destroyed its upgraded form . History . According to Rex Goodwin , since ancient times , Turbo Duel ing has been a ritual designed to fight and seal the darkness , and that the " Duel Dragons " were specifically designed for such rituals . In the past , they were fought on horseback . He says they are cards which sealed the dragonic power of the priests who controlled them , and adds that controlling or being controlled by that power depends on the strength of the Duelist ' s mentality . Because of that , he organized the D1GP in order to gather Duelists with strong mentality in order to control the " Duel Dragons " , and according to him , save the world from Skeleton Knight . However , his true intentions were later revealed to be reviving and controlling the Ultimate God through the Ritual , to which he needed strong Duel Priest s and Priestesses . Five dragons ( " Stardust Spark Dragon " , " Hot Red Dragon Archfiend " , " Blackfeather Darkrage Dragon " , " Ancient Pixie Dragon " and " Power Tool Mecha Dragon " ) belonged to Priests of Light in the past , plus " Black Rose Moonlight Dragon " , who belonged to a Duel Priestess . They were passed to new Priests and Priestess in the present by Rex and the Skeleton Knight , reviving the ancient ritual . Usually , the " Duel Dragons " cards are blank , and only take form after obtaining a holder . Rex Goodwin and the Skeleton Knight seem to possess all of the " Duel Dragon " cards in the present , and distribute them to powerful Duelists , which they choose through several methods . Some include : After Rex obtains the Ultimate God ' s power , he claims that all cards , including the " Duel Dragon " cards , were born from the Ultimate God , who is their master . With the Ultimate God ' s power , Rex gains control of the " Duel Dragons " of all Duel Priests and Priestesses , making their cards turn blank . However , their prayers ultimately awakens the dragons ' souls and release them from the Ultimate God ' s control , allowing Yusei to use them for their real purpose : to seal the Ultimate God and save the world from its darkness .
