The main characters and their Signer marks. From top to bottom: Yusei Fudo, Jack Atlas, Crow Hogan, Akiza Izinski, Luna and Leo.

Yusei Fudo (不動 遊星 Fudō Yūsei?)Script error: No such module "anchor". Voiced by: Yuya Miyashita (Japanese), Frank Frankson (English)
Yusei is the main protagonist of the series, a young man who grew up in the Satellite. When he travels to New Domino City in order to retrieve his Stardust Dragon from Jack Atlas, he soon discovers that he is a Signer, a person chosen to bear the mark of the Crimson Dragon. Whilst initially bearing the mark of the Crimson Dragon's tail, following his battle with Goodwin, it is replaced with the dragon's head. He is a cool and collected duelist who believes no card is useless. He uses a "Warrior" and "Synchron" deck which focuses on managing small monsters of various levels in order to summon out powerful Synchro Monsters, such as Junk Warrior. His key card is Stardust Dragon and later obtains two further evolutions; the powerful Majestic Star Dragon and the Accel Synchro monster, Shooting Star Dragon.
Jack Atlas (ジャック・アトラス Jakku Atorasu?)Script error: No such module "anchor". Voiced by: Takanori Hoshino (Japanese), Ted Lewis (English)
Jack is known as the "Absolute King of the Turbo Duel", and was once Yusei's best friend, but they became bitter rivals after Jack stole Yusei's Stardust Dragon and Duel Runner and left for New Domino City. Now, as a former resident of Satellite, he must hide his past from the rest of society. But he was defeated by Yusei Fudo in the championship round of the Fortune Cup. He starts off as very arrogant and cruel, but his conscience is revived thanks to Carly Carmine, who heals his wounded heart and teaches him to let "the real Jack Atlas" live, and become a good person. His signature card is also a Synchro monster, Red Dragon Archfiend (Red Demon's Dragon in the Japanese version) which, when granted the power of the Signers, can be upgraded to Majestic Red Dragon. He later achieves a Burning Soul which can summon out Red Nova Dragon. He plays a "Power" Deck, focusing on quickly summoning powerful monster to obliterate his opponent's defenses. Jack is one of the five Signers, the chosen ones of the People of the Stars, and carries the Crimson Dragon's Wings. He has attracted Mina, Carly, and the waitress Stephanie.
Akiza Izinski / Aki Izayoi (十六夜 アキ Izayoi Aki?)Script error: No such module "anchor". Voiced by: Ayumi Kinoshita (Japanese), Bella Hudson (English)
She is the main female protagonist that doubled as antagonist. Akiza appears as a cold and pathologically sadomasochistic girl with the power to bring the monsters and magic of Duel Monsters to life, a psychic power ability only used through anguish and cruelty. Because of this, and her abilities, she is called the "Black Rose" ("Black Rose Witch" in Japanese). Because of this, she earlier chose to distance herself from people, believing her power to be caused by the Dragon birthmark she possesses, but became more 'open' after her second Duel with Yusei. She holds strong feelings for Yusei. She is the third Signer, who plays a deck based around Plant-Type Monsters and holds the "Black Rose Dragon". While she is the Black Rose, she hides her appearance with a tattered cloak and covers her face with a mask. She, along with Leo, Luna, and their friends, attends the Duel Academy after the Dark Signers' defeat and later becomes a Turbo Duelist, acting as a reserve member of Team 5D's in the WRGP.
Leo / Rua (龍亞?)Script error: No such module "anchor". Voiced by: Ai Horanai (Japanese), Cassandra Morris (English)[1]
Leo is the lively and blundering twin brother of Luna. He plays a "Morphtronic" deck ("Deformer" in Japanese, also written as "D-Former"), with monsters based on Transformers that have different abilities in attack and defense position. He idolizes Jack, and even owns figurines of him, his Duel Runner, and his Dragon. He duels in the Fortune Cup tournament in place of his sister, but lost in the first round to Greiger. He has some knowledge of the dragon birthmarks, since his sister has one, and was shocked to discover that Yusei has one too. Whilst he is not a Signer himself, his key card, Power Tool Dragon, is similar to one of the five dragons. Leo's original dub name was going to be Luca, but 4Kids changed it.
Luna / Ruka (龍可?)Script error: No such module "anchor". Voiced by: Yuka Terasaki (Japanese), Cassandra Morris (English)[2]
Luna is the calm and collected twin sister of Leo. She plays a "Fairy/Spirit" deck, and gained the ability to speak with Duel Monster spirits, after an incident that occurred eight years ago. Luna fell into a coma at the age of three, but recovered after a month, thanks to Leo, who was by her side the whole time calling her name. After she awoke, she claimed to have visited the Duel Monsters Spirit World in her dreams, where she met the spirit of Ancient Fairy Dragon, who charged her with the duty of keeping the spirit world safe. Luna was invited to enter the Fortune Cup, however she had no interest in participating. Leo thought of the idea to enter in her place. She dislikes dueling, as speaking to monster spirits tires her. She is also one of the five Signers. Her birthmark is one of the Crimson Dragon's Claws. Her dragon is Ancient Fairy Dragon, which she retrieved after defeating Devack.
Crow Hogan (クロウ・ホーガン Kurō Hōgan?)Script error: No such module "anchor". Voiced by: Shintaro Asanuma (Japanese), Jason Griffith (English)
Crow is one of Yusei's friends and a thief. His parents died when he was little, and he was alone until Duel Monsters gave him friends and taught him how to read. He passes his knowledge on to a group of children he looks after, and his motives for stealing are to provide for them. He later became a member of Team Satisfaction with Yusei, Jack, and Kalin, but he quit due to Kalin taking the fun out of dueling, both from himself and his opponents. His custom Duel Runner, Blackbird, has a built in Flying Formation used to cross large gaps and can also fire hooks to change direction. After facing Goodwin alongside Yusei and Jack, Yusei inherits the Dragon Head birthmark while he inherits Yusei's Tail Birthmark, becoming a Signer himself. He uses a Blackwing deck that can quickly summon monsters (a.k.a. "swarming") and use their abilities to win a duel, and his main Synchro Monsters are Blackwing Armed Wing, Blackwing - Silverwind the Ascendant, and Blackwing Armor Master. He later obtains his own Signer Dragon, Black-Winged Dragon. In the third season Crow opens a delivery service and his Duel Runner is the main vehicle, naming his business "Blackbird Delivery".

Allies

Tetsu Trudge / Tetsu Ushio (牛尾 哲 Ushio Tetsu?)Script error: No such module "anchor". Voiced by: Kouji Ochiai (Japanese), Dan Green (English)
Trudge is a Security officer who observes the residents of Satellite. He initially duels using a "Guard" deck, but after his first clash with Yusei, he upgrades to a specially-designed "Pursuit" deck, with Goyo Guardian as its main Synchro of choice. He has a violent character but also great pride as a duelist and for this Yusei respects him. After losing to Yusei, he vows to defeat and arrest him, no matter how long it takes. After the first confrontation between Yusei and the Dark Signers, Trudge falls under their control, becoming a Dark Signer himself, and challenges Jack to a duel while he was still recovering from his injuries from his Fortune Cup finals match against Yusei, using a Worm-based deck that focuses on Deck Destruction. Just like the other brainwashed Dark Signers, Trudge gets back to normal after being defeated by Jack. He later reappears to help Mina spy on Jack and brings the signers to Martha's place where he develops a deeper respect to the people of Satellite. He has also shown to have a crush on Mina, and is incredibly jealous of Jack to the point he gains super strength. As time goes on, he becomes less hateful and shows more concern for his allies. Following the Dark Signer incident, he becomes Mina's assistant in an Investigation unit. He is also an examiner who tests those looking to acquire a license for Turbo Duels. It has been revealed that he is the same Tetsu that picked on Yugi at Domino High.
His character is based on Ushio, to whom Yugi Muto challenged his first Shadow Game. In the dubbed version, Trudge has a rivalry with Yusei going for some time now. The pilot dub shown at Comic-Con referred to him by his Japanese name, Ushio, rather than Trudge. In Yu-Gi-Oh! 5D's: Wheelie Breakers, his full English name is Officer Tetsu Trudge.

Mina is Jack's secretary. She is often very concerned over Jack and tries her best to be useful despite the fact that he is always cold towards her. She is the only one that know Jack's true reason of fighting the Dark Signers: Carly. She has shown to have feelings for Jack (though he doesn't seem to reciprocate) and envy's Carly for the attention he gives her. Following the Dark Signers incident, she becomes a chief in the Special Security Investigation with Trudge as her assistant.
Lazar / Yeager (イェーガー Yēgā?)Script error: No such module "anchor". Voiced by: Tetsuya Yanagihara (Japanese), Marc Thompson (English)

Antagonists

Dark Signers

Dark Signers are the antagonists of the second arc of the show, who go against the Crimson Dragon and the Signers. Dark Signers are born when someone who has died, usually someone wanting revenge from what a Signer does to them, is resurrected by an Earthbound Immortal (Earthbound God in the Japanese version), evil entities imprisoned in the Nazca Lines by the Crimson Dragon. Infused with dark powers and dark cards, the Dark Signers are able to form a barrier around their opponents, initiating a Shadow Duel where attacks from monsters cause real damage. Sometimes if the Dark Signer is showing weakness or resistance, the Earthbound Immortal itself can take over its body. Dark Signers have special cards called Dark Tuner Monsters that can summon Dark Synchro Monsters with a negative level. They also have an Earthbound Immortal, representative of their birthmarks. When summoned, these monsters sacrifice the souls of anyone caught within the Dark Signer's geoglyph (with the exception of the duelists, Signers, and anyone protected by a barrier emitted by a Signer's birthmark.) Their common attribute is to be able to attack directly and not be chosen as a target, although some circumstances allow them to attack monsters and be attacked themselves. In the anime, they are also unaffected by Spell and Trap cards.

There are also Dark Signers-like figures (called Shadow Drones in the dub) who are recruited by Roman using his spiders to control them, though they only have access of Dark Tuner and Synchro Monsters. When these Dark Signer are defeated, their Mark of the Shadows and Deck disappear and they lose memory of when they were possessed. However, according to Goodwin, a true Dark Signer cannot be returned to normal since they have already died as well as their duels end with the losing duelist being killed (in the dub, they are sent to the Netherrealm). When a true Dark Signer is defeated, all the souls that were used for summoning their Earthbound Immortal are freed (this also seems to apply to non-Dark Signers who were defeated in Shadow Duels). After Goodwin and the King of the Netherworld are defeated. Goodwin and Roman pass onto the afterlife whilst Carly, Misty, Devack and Greiger are revived with no memory of when they were Dark Signers. Kalin is actually shown later that he does have his memories of being a Dark Signer. It's speculated since he willingly became a Dark Signer that he kept the memories unlike the others.

Rex Goodwin (レクス・ゴドウィン Rekusu Godowin?)Script error: No such module "anchor". Voiced by: Shinya Kote (Japanese), Pete Zarustica (English)
Rex Goodwin is the original leader of the Yliasters and the chief of public maintenance for New Domino City. He, alongside his brother Roman, was an assistant to Professor Fudo during the Zero Reverse accident. With his elitism, he transformed the city into a hierarchical society. He shows interest in the Signers, explaining their significance to Jack prior to holding the Fortune Cup to gather the remaining Signers and awaken their powers. It is seen that he can be aggressive if necessary, but usually keeps a calm demeanor. Known as a legendary D-Wheeler, Goodwin lost his left arm around the time he didn't finish Daedalus Bridge, the only means for the Satellite to be connected with the city, and had it replaced with a cybernetic one which doubles as his duel disk. He additionally possesses his brother's severed arm with the head part of the Mark of the Dragon. In the dub he claims to be the fifth signer, but it is not actually so. But after the deaths of the Dark Signers, Rex reveals himself to have become one of them during a duel with Roman, having the condor birthmark on his back and control of the Earthbound Immortal Wiraqoacha Rasca. Furthermore, he integrates his brother's arm onto himself to gain the power of a Signer as part of his plan to use both the Earthbound Immortals and the Crimson Dragon to recreate the world in his image. He is defeated by the joint efforts of Yusei, Jack and Crow, and passes onto the afterlife with Roman.
Roman Goodwin / Rudger Goodwin (ルドガー・ゴドウィン Rudogā Godowin?)Script error: No such module "anchor". Voiced by: Taketora (Japanese), Marc Thompson (English)
The leader of the Dark Signers. He possesses a birthmark resembling the Spider Nazca line and can use it send out spiders that can possess civilians, turning them into Dark Signers, giving them Shadow powers and Dark Tuner and Synchro Monsters. They can also be used as a means of surveillance, reporting all it has found once it returns to its owner. He reveals himself to be Rex Goodwin's big brother and an assistant to Professor Fudo (Yusei's Father), until he met a mysterious man from Yliaster, that told him to look into Ener-D's light and learn of the Earthbound Immortals' battle against the Crimson Dragon. Though revealed to be the Fifth Signer, Roman betrays Professor Fudo and causes the Zero Reverse incident after ripping his own arm off and giving it to Rex, telling him to unite Signers and defeat him. The resulting explosion transformed Roman into a Dark Signer.
Like Rex, he has a bionic arm in place of it, which he uses to trigger explosives. He is defeated by Yusei, however before he dies he triggers an explosion that sends Yusei down into the Ener-D's light. His deck focuses around Spider type monsters, and specialises in changing an opponent's monster into defense mode to obtain counters for summoning his Earthbound Immortal Uru, who can control an opponent's monster by sacrificing one of their own. He's later on defeated by Yusei, but sets off an explosive in his mechanical arm before crumbling to dust, so that Yusei would fall into the gate to the Underworld. His spirit remained in the world until Goodwin is defeated, joining his brother in the afterlife.
Kalin Kessler / Kyosuke Kiryu (鬼柳京介 Kiryū Kyōsuke?)Script error: No such module "anchor". Voiced by: Yuki Ono (Japanese), Marc Diraison (English)
Kalin was once the leader of a group called Satifaction ("The Enforcers" in the English Dub.)with Yusei, Jack and Crow, who would go around battling rival duel gangs (In the English Dub, Satifaction defeat Satellite gangs in order to make Satellite a safer place; after defeating all the gangs, Kalin find Security as the enemy). As time went on however, he became a bit more sadistic against his opponents and started going out of control as a result, which caused Crow, Jack and Yusei to leave. Kalin decides to provoke Security and attacks a Security officer. When Yusei tries to take the blame for it, his attempt fails and Kalin is arrested. Misunderstanding the situation and believing Yusei had sold him out, he later becomes a Dark Signer, branded with the giant birthmark, in order to get his revenge on him. His first duel is cancelled due to a malfunction on Yusei's Duel Runner, but he loses his second duel with him, when Yusei's feelings allows him to synchro summon Majestic Star Dragon. He forgives Yusei before disappearing. In the 4kids version he admits he was wrong to think that Yusei sold him out.
He is revived after Goodwin's defeat, but still has memories of being a Dark Signer and the crimes he committed. He goes to a place called Crash Town looking for a way to die, and ends up duelling Yusei again. They are soon both captured and taken to work in a mine, though Yusei manages to break him free. Whilst assisting two siblings, West and Nico, in rescuing their father, Kalin regains his will to live.
He uses an Infernity Deck that specialises in effects used when the player has 0 cards in his hand. His Dark Signer deck additionally has two key monsters; a Dark Synchro Monster called One-Hundred Eye Dragon, which can gain the effects of the monsters in his graveyard, and the Earthbound Immortal Ccapac Apu, which inflicts additional damage for every monster it destroys. His Dark Signer birthmark is based on the giant Nazca line. In Crash Town, it is revealed that he has his own Ace, the LV8 Synchro Monster, Infernity Death Dragon.
Carly Carmine / Carly Nagisa (カーリー渚 Kārī Nagisa?)Script error: No such module "anchor". Voiced by: Li-Mei Chiang (Japanese), Veronica Taylor (English)
Carly is a reporter who came from the country to seek out her dreams (in the English dub, she is a weblogger working as an intern who hopes to become a true reporter). She tends to get pushed around by others as she attempts to obtain a big scoop and is generally called "Stutter Stammer Carly" due to her nervousness. She uses a "Fortune Fairy" Deck which she uses to predict her fortune and have tips for the day. Despite her anxiety, she is a truly good person and gets her happiness by seeing others try hard.
She safeguarded Jack for a short while and garners some affection for him, but he leaves her behind to avoid her getting involved with the Signer battles. However, she infiltrates the Arcadia Movement and ends up being killed after plummeting through a window as a result of Sayer's Psychic Monsters during their duel (In the dub, her fall was prevented by the Dark Signers). She is revived as a Dark Signer herself, with an alternate vengeful personality that brandishes a birthmark of the Hummingbird, a "Fortune Lady" deck with monsters that grow gradually stronger with each turn, and the Earthbound Immortal Aslla Piscu, which destroys all her opponents monsters and inflicts damage accordingly should it ever leave the field, although she is never shown with any Dark Synchro monsters. But despite the new persona, the true Carly still exists within her and desires to be with Jack. She ends up dueling Jack, where she shows him a vision where they are together as Dark Signers, but Jack aims to reach her true desires. He confesses his love for her and is willing to sacrifice himself to make Carly understand. While he manages to reach her, the Earthbound Immortal takes over Carly and Jack is forced to fight her. Jack tries to play a trap card that would make the duel end up in a tie but Carly activates one her trap cards before Jack did, ending the duel with her as the loser. Carly tells Jack that she will always be cheering him on and that she loves him, before dying. She is revived by Goodwin as he faded away. She reappears in the third season, occasionally helping Jack out. While her memories of her time as a Dark Signer disappeared, her feelings for Jack have not.
Misty Tredwell / Misty Lola (ミスティ・ローラ Misuti Rōra?)Script error: No such module "anchor". Voiced by: Junko Minagawa (Japanese), Rebecca Soler (English)
Misty is a famous model who can read someone based on facial appearance. When her younger brother, Toby, is allegedly killed by Akiza's powers (disappeared in the English dub), Misty's depression causes her to drive off a cliff, leading her to become a Dark Signer with the lizard birthmark and the Earthbound Immortal - Ccarayhua, which destroys all cards in play on both sides of the field when destroyed.
She seeks out Akiza and duels her with the intent of revenge. Their duel however is postponed due to the aftershock of Carly's duel with Sayer, so she waits for her at the Lizard control unit. She duels Akiza again in the hall of mirrors of an old carnival site, showing Akiza events of the past to dwindle down her spirit. However, she eventually learns that Sayer was the one who killed Toby, and after using Ccarayhua to take revenge on him, she is defeated by Akiza to stop the Earthbound Immortal inside her. She is revived by Goodwin as he faded away.
She uses a Reptiless Deck, her ace monster being Bad End Dragon, featuring cards to either seal her opponents draw phase or remove all her opponents monster attack power then forcing them to attack her monsters, drawing them into suicide attacks. Like Carly, she is never seen with any Dark Synchro monsters. She also appears to be able to use lizards as surveillance, much like Roman's spiders.
Devack / Demak (ディマク Dimaku?)Script error: No such module "anchor". Voiced by: Kenji Nomura (Japanese), Scottie Ray (English)
Devack is another Dark Signer who has Ancient Fairy Dragon in his possession. Devack hates the Signers although his reason for doing so is never explained. He possesses a dark birthmark of the monkey and the Earthbound Immortal Cusillu. During the chaos surrounding Carly and Misty's duels, he frees Greiger who was being escorted by Security in order to recruit him to the Dark Signers. He duels Leo and Luna is in the Spirit World, but is defeated and turned into dust when Luna reappears and reclaims Ancient Fairy Dragon. He is the first Dark Signer to be defeated, when he is beaten by Leo and Luna. After Goodwin's defeat, Devack is revived.
Like his birthmark, his deck features Monkey monsters, including the Dark Synchro Monster, Zeman the Ape King, which focuses around increasing the power of his monsters in play through the number of monsters in his graveyard. He is also able to use captured spirits from the Spirit Realm in order to summon his Earthbound Immortal Cusillu, who can avoid destruction and cut the opponents life points in half as long as he sacrifices his other monsters in order to do so.
Greiger / Bommer (ボマー Bomā?)Script error: No such module "anchor". Voiced by: Keiji Hirai (Japanese), Sean Schemmel (English)
Greiger is a physically well-built Duelist first met in the Fortune Cup tournament, battling first against Leo (which was posing as Luna), then again in a Turbo Duel against Crow, although he was trying to duel Yusei. He apparently originates from arid Central America, which he believes that Goodwin used Greiger's village as the site of an "experiment" to summon the Crimson Dragon, that completely destroyed the village, leaving the whereabouts of Greiger's younger brother and sister unknown. Enraged to learn the truth prior to his match with Yusei, Greiger attempts to take revenge on Goodwin for his village's destruction.
When he lost, Greiger reveals this to the audience before using his Duel Runner to rocket toward the box room to take out Goodwin. But Yusei stops Greiger and he is soon arrested by Security for his attempt of Goodwin's life, publicly labeled insane to discredit his word against Goodwin and sentenced to death. However, he is later set free by Devak and brought before Roman who made him a Dark Signer himself, giving him the whale birthmark, to extract his vengeance on their mutual enemies Goodwin and Yusei. But while hunting them, Greiger ends up dueling Crow, where he learns that the Dark Signers were the ones that caused his village's destruction, and its residents, including his brother and sister, are being used for his Earthbound Immortal's summoning until Crow defeats the monster to free Greiger's people.
