Signer The Signers are the only group that can summon the legendary Crimson Dragon , the embodiment of the red star . There are six people in the world that have the Mark of the Dragon and Signer Dragon s that fit into the legend . Each birthmark represents a part of the Crimson Dragon , as these marks themselves are actually broken pieces of the Crimson Dragon itself , that later were divided into six parts . Thus engraved and sealed into six people called " Signers " . The present day Signers in " Yu - Gi - Oh ! 5D ' s " include Yusei Fudo , Jack Atlas , Crow Hogan , Akiza Izinski , Luna and Leo . Although Rex Goodwin has stated he is the fifth Signer in the dub , this contradicts the original anime until later on , when he infuses Roman ' s arm onto himself thus only technically making him the fifth Signer for the time by proxy . It is known that their powers were awakened by Rex Goodwin himself through the Fortune Cup . According to Goodwin , he did it so that they would defeat their archenemies , the " Dark Signer s " , along with the task of closing the door to the " Netherworld " . Although according to the Star Guardian , to those who are Signers exist within some kind of " fate " , derived from the Dragon Star , one which cannot be escaped from . That strange fate was the one responsible for the fact that the four signers came together . Thus the " Fate of the Signers " unites each and every one of Yusei , Jack , Akiza , and Luna ' s own destiny together in order to guide them all . Nonetheless , according to Goodwin the four of them are not only duelists chosen by the Dragon Star himself , but they are also the reincarnations of the ancient Signers themselves . Also , it was already predicted thousands of years ago the four of them would encounter one another . History . Before " Black - Winged Dragon " was revealed as a Signer Dragon , " Life Stream Dragon " was shown participating in the ancient battle between the Crimson Dragon and the Earthbound Immortal s . It is unknown what exactly happened to " Black - Winged Dragon " after the battle against the Crimson Devil , Red Nova . The same goes for " Life Stream Dragon " after the battle against the Earthbound Immortals before it was encased in armor to form " Power Tool Dragon " . Yusei Fudo ' s mark was originally the Tail , Jack Atlas ' represents the Wings , Akiza Izinski and Luna ' s each represent a claw ( the former ' s being the Foot and the latter ' s being the Hand ) , and Roman Goodwin ' s was the Head . However , during the ultimate Shadow Turbo Duel against Rex Goodwin , the Tail and Head Marks are transferred : the Head is now under the possession of Yusei while the Tail ( formerly Yusei ' s ) chooses Crow Hogan as its new owner , making him the new fifth Signer ( the Head Mark signifies a leader of sorts , choosing Yusei as its new owner ) . Ultimately , a new mark , the Heart ( seen on the full Dragon Mark in the claws of the Crimson Dragon ) , was bestowed to Leo when he sacrificed himself during his Duel against Aporia alongside Luna and Jack and was revived , making him the new sixth Signer . It is interesting to note that both Jack and Roman had their marks from birth whereas Akiza got her mark at a young age , Luna received hers after she went to the Spirit World the first time , Yusei did not receive his until Episode 5 and it was not permanently burnt in until Episode 25 , and Crow and Leo received their ' s in Episodes 64 and 142 respectively . Unlike their Dark Signer counterparts whose Mark of the Shadows and Earthbound Immortals are connected , a Signer ' s Mark of the Dragon and Signer Dragon are connected only to the Signer and not to each other , as shown when Yusei inherited the Head Mark but kept " Stardust Dragon " . A Signer ' s mark throbs and glows while they are in close proximity of one of the Dragons when it is fighting with a great deal of determination , particularly for the sake of their Signer . A Signer ' s mark glows and painfully digs into their arm , when they are in the presence of a Dark Signer . A Signer ' s mark also glows while in the company of the Team Ragnarok .
