Signer Dragon The Signer Dragons are a series of Level 7 - 8 Dragon Synchro Monster s introduced in " Yu - Gi - Oh ! 5D ' s " . These legendary dragons play a part in the legend of the Crimson Dragon , as well as being connected to the Signer s themselves . That connection being that these legendary beasts , who actually joined forces with the Crimson Dragon , were the ones who sealed an evil within the Nazca Lines . That very same evil , now known as the " Earthbound Immortal s " , reappeared once again in the world as Duel Monsters cards used by the Dark Signer s . Every Signer Dragon has been featured in the anime and has been released in the OCG / TCG . They are : " Stardust Dragon " , " Red Dragon Archfiend " , " Black Rose Dragon " , " Ancient Fairy Dragon " , " Black - Winged Dragon " and " Life Stream Dragon " . In the anime , Professor Fudo gave the " Stardust Dragon " , " Red Dragon Archfiend " and " Black Rose Dragon " cards to Rex Goodwin . These cards were originally designed so that their corresponding Signer could activate the safety switches for the Ener - D system . Variations . Reflecting the rivalry between the two main characters Yusei Fudo and Jack Atlas , " Stardust Dragon " and " Red Dragon Archfiend " are the only Signer Dragons to have different upgraded versions . It is worth noting , however , that " Life Stream Dragon " has its downgraded , armored version , " Power Tool Dragon " , which is a required Synchro Material for its Summon . / Assault Mode . " Stardust Dragon " and " Red Dragon Archfiend " have their own : / Assault Mode s : " Stardust Dragon / Assault Mode " and " Red Dragon Archfiend / Assault Mode " having 500 more ATK and DEF , two more Level s and an " upgraded " effect of the original monsters . Both of these monsters were Summoned by Yusei and Jack in a special episode . Majestic . The " Majestic " Dragons are upgraded forms of " Stardust Dragon " and " Red Dragon Archfiend " , Summoned by Tuning " Majestic Dragon " with one of the Dragons and one Level 1 non - Tuner monster . They have powerful effects , but return themselves to the Extra Deck during the End Phase while reviving their previous form from the Graveyard . There are 2 " Majestic " forms ; " Majestic Star Dragon " and " Majestic Red Dragon " , which were used in the anime by Yusei Fudo and Jack Atlas , respectively . Malefic . " Stardust Dragon " is the only Signer Dragon with a " Malefic " form ; " Malefic Stardust Dragon " . This card was used in The Tenth Anniversary Movie by Paradox . It has released in both the TCG and the OCG . It is highly unlikely that " Red Dragon Archfiend " will receive a " Malefic " form due to " Stardust Dragon " being the only monster card that Paradox stole from the 5D ' s timeframe . Cosmic Synchro . The Cosmic Synchro Monster s are upgraded forms of " Stardust Dragon " and " Red Dragon Archfiend " . They are not Synchro Summon ed in the usual method . The opening theme BELIEVE IN NEXUS originally confirmed the existence of what was later revealed to be the Accel Synchro counterpart / evolution of " Stardust Dragon " . Stardust ' s counterpart ( " Shooting Star Dragon " ) is the only Accel Synchro evolution of a Signer Dragon . Although Jack ' s new ace monster " Red Dragon Archfiend " ( " Red Dragon Archfiend ' s " counterpart / evolution ) is not an Accel Synchro , it uses a method called " Double Tuning " to achieve its evolution and is in the same power range as " Shooting Star " . Both monsters were released in Starstrike Blast . Their ATK seems to be their original counterparts ' Majestics forms ' ATK - 500 ( Majestic Star Dragon ' s ATK : 3800 - 500 = 3300 ( Shooting Star Dragon ' s ATK ) ) ( Majestic Red Dragon ' s ATK : 4000 - 500 = 3500 ( Red Nova Dragon ' s ATK ) ) . Also their DEF is equal to the ATK of their original forms . Limit Over Accel Synchro . The Limit Over Accel Synchro monster is considered to be the ultimate type of Synchro Monster . In the anime , summoning a Limit Over Accel Synchro requires the duelist to achieve Over Top Clear Mind . Reaching this state will cause the duelist , and their Duel Runner to become a shining gold color , implicating the god - like power involved with performing this type of Synchro Summon . Limit Over Accel Synchros are Synchro Summoned in a similar way to Cosmic Synchro Monsters . However , they do not require their corresponding Signer counterpart in their summoning requirements . They use 2 normal Synchro Monsters , plus 1 Tuner Synchro Monster , which is the same to how Delta Accel Synchro Monster s are Synchro Summoned . " Shooting Quasar Dragon " must be Synchro Summoned , and it cannot be Special Summoned any other ways . However , despite this downfall , it is able to attack once for every Synchro Material used to Synchro Summon it , and it can negate one card or effect per turn . It can also call for backup by Special Summon ing a " Shooting Star Dragon " from the Extra Deck if it ever gets removed from the field . In the anime , it was Synchro Summoned using all of the other Signer Dragons ( the exception being , of course , " Stardust Dragon " ) as Synchro Materials , utilizing the effect of " Life Stream Dragon " to reduce their Level s to 1 . Downgraded . " Life Stream Dragon " is the only Signer Dragon to have a downgraded form , " Power Tool Dragon " , which is a mechanized / shell form of itself . " Power Tool Dragon " searches for Equip Spell Card s and cannot be destroyed when it is equipped with one . This sets up for " Life Stream Dragon " who uses Equip Spells in the Graveyard for protection . Duel Dragons . In the " Yu - Gi - Oh ! 5D ' s " manga , the Signer Dragons do not appear . Instead , a similar series known as the Duel Dragon s is featured . Many of them are slightly redesigned Signer Dragons , named " Ancient Pixie Dragon " , " Black Rose Moonlight Dragon " , " Blackfeather Darkrage Dragon " , " Hot Red Dragon Archfiend " and " Stardust Spark Dragon " . ( Only the Duel Dragon counterpart of " Life Stream Dragon " remains unknown , although as " Power Tool Dragon " is stated to be a Duel Dragon in its own right , there may not be one . ) 5 of these Signer Dragons ' counterparts and 1 downgraded Signer Dragon ' s counterpart are currently released in the " TCG / OCG " . Playing style . There are various kinds of playing styles for each dragon , especially " Stardust Dragon " and " Red Dragon Archfiend " . All of the dragons ( except " Life Stream Dragon " ) have no specific Summoning condition s , making them easy to Synchro Summon , so they can be used in almost any Extra Deck .
