Syrus Truesdale, known in Japan as Sho Marufuji (
Syrus's character design was overseen by Kenichi Hara. His usual outfit consists of the standard Duel Academy uniform with alternating colors over the course of the series. The designs for all three uniforms worn by Syrus are identical in basic makeup. With his red uniform, a yellow shirt is worn underneath the jacket, whereas with his yellow uniform, this is reversed. With his blue uniform, the shirt is black, and the collar has buttons not present in his other incarnations - similar to Chazz's uniform before he attended North Academy. The blue uniform also has fins in the back similar to his brother's outfit also not on his other uniforms. His blue hair (of a lighter tint than his brother's) is sectioned in three layers, his grey eyes positioned between the three bangs closest to his face and behind a pair of round-lensed glasses. He carries an Academy-issued Duel Disk on his left hand. He has also been shown wearing the Academy jersey when necessary. In episode 8, during a flashback sequence when he was young, he wore a yellow collared shirt with blue shorts and black sneakers. At the end of Episode 64, while searching for Jaden he wears an explorer outfit, consisting of a khaki hat, a khaki collared shirt with a blue undershirt, khaki shorts, white socks, and his (at the time) Ra Yellow uniform shoes.
In the first season of the dub, Syrus often makes a joke about how his brother has amazing Dueling skills while apparently he always had "the looks".
Syrus is a insecure and unconfident Duelist. However, he not only grows into becoming a better Duelist, but a more brave and confident person.
He is a very loyal friend, often thinking of Jaden as a second big brother figure.
Syrus is easily captivated by any woman, real or otherwise, who happens to catch his eye. However, these feelings are superficial as he often moves from one crush to another. His main crush is the Monster Spirit of "Dark Magician Girl". He has also displayed crushes on the cards "Thunder Nyan Nyan", "Maiden in Love" and "Gamble Angel Bunny".
In the original version, he ends the majority of his sentences with "suu" (an elision of "desu"). Furthermore, he calls Judai "Aniki," meaning "big brother," while referring to him as "Bro" in the English-language manga. In the English anime, Syrus also refers to Jaden simply as "Jay." In the third season of the original anime, however, Syrus starts to call Jaden by his first name because of Jaden's selfish actions during his Duel against Brron, Mad King of Dark World that led to the deaths of Chazz, Alexis, Hassleberry and Atticus. For these transgressions he begins taking on the self-appointed role as an observer of the season's events. However by the end of the third season his faith in Jaden is restored and he begins to call him "big brother," again.
Starting with the third season of the dub, Syrus is able to break the fourth wall. This is shown when he says he's just there for amusement and would never move the plot along, when Jesse and Hassleberry are ignoring him when he's tied up, he says "I know I'm not the star but come on, a little respect people" and that he carried Jaden's water for three episodes. He's even admitted that he doesn't move the plot along, and complains that nobody listens to him. Another instance is when they start discussing where Wheeler originally was worked on; Syrus says "Man, that was a weird episode!" When he ran away from Jaden in the third season, he claimed that the Syrus spin-off show had begun. During the episode he spoke as if each of his actions were the next episode in the spin-off. In the dub he tends to say "oh man".
His Japanese given name means "soar" or "fly", and is homophone for "small", signifying he is the younger brother. His Japanese last name means "Perfect Wisteria", with 丸(maru) meaning round, circle or perfection and 藤(fuji) meaning "Wisteria". His English given name comes from the Persian word Kuros, which means Sun. It could also be a different form of Cyrus, from the Ancient Greek Κυρος (pronounced Kyros), which means "young" or "far-sighted".
Syrus has made progress as a Duelist throughout the series. From the onset, he faced Jaden in preparation for a Tag-Team Duel, but, priding himself on finding a way to outdo his roommate, overlooked the abilities of his own cards. It was for this same reason that Zane forbade him from using the "Power Bond" card, for Syrus was unable to cope with its potential drawback.
During the second season, Syrus is given an opportunity to advance to Ra Yellow, should he be able to defeat Missy. Feeling that he should not shoulder his brother's legacy, Syrus gives his "Power Bond" card to Chazz Princeton to pass to Jaden before the start of the Duel, though Jaden convinces him to put it back in his Deck after the Duel.
In episode 55, Syrus develops a rivalry with Tyranno Hassleberry over which of the two is better suited to being Jaden's best friend (in the Japanese version, it is over who has the right to call him "big brother"). They constantly argue and fight, prompting their repetitive separation by Alexis Rhodes. By episode 64, their rivalry comes to a temporary halt, when the two Duel to settle matters once and for all. Before the last blow is dealt, Tyranno discovers that Syrus went without food or sleep to search for Jaden, who had gone missing since his defeat at the hands of Aster Phoenix. Seeing Syrus' devotion to their friend, he chose not to activate his "Jurassic Impact" card, which would have wiped both players out simultaneously.
During the field trip to Domino City, Syrus teams up with Tyranno in a Duel against the first duo of The Light Brigade, Frost and Thunder. Although the two are pinned down by their opponents, who tuned their Decks specifically to combat their cards, they end up pooling their efforts to combine their monsters into "Super Vehicroid Rex Union". Despite their teamwork, however, Frost ends the Duel by wiping out all players but himself, and promptly drags them to his master's lair, from where they are transported to Kaiba Land as bait for Jaden and Aster by order of Sarina.
As he observes his brother's actions following his "rebirth," Syrus notes Zane's newfound disrespect for his own cards and opponents. He dismisses the barbaric persona, refusing to believe that his brother has sunk so low. Determined to bring his brother back to his senses, Syrus acknowledges the inevitability that the two of them will face one another. During the Genex Tournament, Syrus and Zane Duel, they are hooked up to electrodes, just as Zane and Mad Dog were in the Underground Duel. Despite his best efforts and Jaden's secret move to place "Power Bond" back into his Deck, Syrus loses, but he does not give up in hoping that his brother can be returned to his former self.
Shortly after the beginning of the third year at Duel Academy, Syrus advances to Obelisk Blue. As a result of Survival Duels being called for by Thelonious Viper, Syrus becomes self-conscious of his worthiness to wear the outfit of the elites, and sets out to prove himself. In the Japanese version, he also wishes to adopt his brother's discarded title, and thus merit the name of "Kaiser Sho" (カイザー翔, Kaizā Shō). Inspired by Jaden's match with Axel Brodie, however, he decides to remain in Ra Yellow, and sets aside his goal for the future. (In the English version he quits the Obelisk Blue dorm stating that Blue wasn't his color and he left Blue to protect Jaden). After Duel Academy is transported to the first alternate dimension, Syrus falls to the Duel Ghouls and becomes one himself.
Later, when Jaden and company venture into another alternate dimension to rescue Jesse Anderson, Syrus is the only one of Jaden's closest friends who isn't sacrificed by Brron. After Jaden wins, he verbally scorns Jaden saying he wants nothing to do with him and up leaving him. While separated from the others, Syrus decides to act as an observer, but later reunites with Aster and Zane when Jaden is released from his possession. After Zane loses to a Yubel-possessed Jesse, Syrus watches Zane die and fade into particles of light before breaking down in tears.
In season 4 Syrus advanced to Obelisk Blue again. Syrus later attempts to finish Zane's Duel with Makoto Inotsume after Zane becomes too weak to Duel, but immediately regrets his decision later as he begins to develop the same heart problems as Zane because of his use of the "Cyberdark" Deck. However, Syrus manages to overcome his problems and defeat Inotsume, thus inheriting Zane's Cyber Dragon Deck later on and promises to improve it. However, he still later falls to Trueman, and is absorbed into the World of Darkness. It is shown within the World of Darkness that Syrus fears that he will be unsuccessful at creating a Cyber Art Pro League with Zane (as it is his brother's dream) and that he will have to be the successor of the Cyber Art when Zane becomes greatly ill (as Zane has his limits). He also fears that he will be unable to make this dream come true due to few to no people and sponsors being interested in it. It is also shown that if Zane dies when Syrus is still unsuccessful at creating a great Pro League, then he will feel relieved that he is finally released from trying to create something he couldn't succeed at creating. He is revived after Jaden defeats Nightshroud.
In the manga, Syrus is a much better Duelist than his anime counterpart, although he is hampered by his desire to not cause pain to his opponents.
In Yu-Gi-Oh! GX Tag Force, Syrus can be selected as a partner. Upon getting his heart level to full, he gifts the player with a "Steam Gyroid" card. He partners with Zane Truesale during the Tag Force tournament if not partnered with the player. During part three, he is brainwashed by Abidos the Third and will Duel the player and their partner alongside the Shadow Rider. He is returned to normal upon defeating him.
Syrus uses a "Vehicroid" Deck, mainly focused on Fusion Summoning his more powerful monsters. He also uses a large quantity of cards dedicated to punishing his opponent's defensive plays such as "Drillroid" and "Shield Crush". Syrus later uses cards that focus on negating an opponent's attacks and shutting down their strategies. When he Duels his brother, Zane comments that Syrus has filled his Deck with cards that protect his Life Points such as "Life Force" whilst using cards such as "Pair Cycroid" and "Mirror Damage" in combination with "Power Bond" to reduce his opponent's. His Deck also features a loop consisting of "Ambulanceroid", "Rescueroid", "Decoyroid", and "Cyber Summon Blaster".
Syrus later comes into possession of Zane's Underworld Deck after he is hospitalized by it, which he combines with his own Deck. By respecting the Deck, Syrus is able to use without any repercussions, and Zane acknowledges that Syrus has surpassed him as a Duelist. It mainly focuses on Mill tactics through cards such as "Power Wall" and "Remove Bomb" which he then takes advantage of with his "Cyberdark" monsters. As the Deck heavily relies on having Dragon-Type monsters in the Graveyard, Syrus uses cards such as "Dragonroid" and "Rebirth Judgment" to combat any form of counter his opponent has to this.
