Syrus Truesdale, known in Japan as Sho Marufuji (丸藤翔, Marufuji Shō), is a former Slifer Red, then Ra Yellow, and now Obelisk Blue student as well as Jaden's best friend. A decent duelist, though hindered by a great deal of self doubt, Syrus' journey toward strengthening himself provides sharp contrast to protagonist Jaden's active determination. Syrus is often a "comic relief" character, partially due him being very nervous a large portion of the time, in a sharp contrast to Jaden's optimistic nature.


Character design

Syrus' design incorporates multiple layers of clothing and a wide range of expressions. Depicted here is the duelist in full Slifer Red regalia from front, side, and rear alongside views of his head from different angles.

Syrus' 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 hidden 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. 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.


Syrus is considered to be the "weaker" younger brother of Zane Truesdale who attends Duel Academy, originally residing in the Slifer Red dormitory along with Chumley Huffington and Jaden Yuki.

Syrus has made progress as a duelist throughout the series. From the onset, he faced Jaden in preparation for a tag 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 to pass to Jaden before the start of the duel (reclaims it afterwards).

In episode 55, Syrus develops a rivalry with Tyranno 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. 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. 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 KaibaLand 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 Disclosure Duels being called for by Professor 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 the Academy is transported to the other world, Syrus becomes one of the zombified students along with Chazz.

Later, when Jaden and company venture into an alternate dimension to rescue Jesse, Syrus is the only one of Jaden's friends who isn't sacrificed by Brron. After Jaden wins, he verbally attacks Jaden saying he wants nothing to do with him. While seperated from the others, Syrus decides to act as an observer, but later reunites with Aster and Zane when Jaden is freed 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. Later Syrus 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 issues as Zane because of his use of the Cyberdark Deck. However, Syrus manages to overcome his problems and defeat Izimu, thus inheriting Zane's Cyber Dragon Deck later on and promises to improve it. Even with his new deck though, he could not defeat Trueman and was thus erased from existence. During Atticus's duel with Nightshroud, he is shown dueling dressed as Hell Kaiser Sho with a suit similar to his brother's dark outfit. He is revived just before Jaden defeats Nightshroud.

In Yu-Gi-Oh! 5D's

In the English version of Yu-Gi-Oh! 5D's, Blister mentions that Truesdale is one of the people he wanted to duel in the Pro Leagues. Truesdale may be interpreted as either Syrus or Zane, as Zane was in the Pro League and Syrus has also accepted an invitation to join.


Syrus in the Manga

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 the past, he held forfeited a duel when his friend was in tears, despite victory being in his hands, prompting Zane to consider him too kind to be a duelist. He still refers to Jaden as bro (he is questioned by Jaden, Alexis and Bastion about this but is interrupted before he can answer), and later thinks that this is because Jaden reminds him of when his brother taught him to duel. Unlike in the anime, the manga version of Syrus sees his brother's lack of regard for his abilities as something to overcome, rather than proof of his inferiority, and is determined to be acknowledged by him. He fights Jaden in a duel to stay at the academy, and insists that Jaden not forfeit the duel for his sake, despite his deck being at stake. Syrus loses, but Jaden acknowledges the duel as fun, and Syrus stays at the academy. Although it is unknown if other characters in the manga view him as such, but Bastion Misawa views Syrus as Jaden's lackey. This thought is revealed (not to other characters) after Bastion finds out Syrus has Alexis' cell phone number. In the tournament, Syrus loses to David Rabb in the preliminaries and Chazz in the first round of the finals, but his skill and resolve impress his brother.


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 actions he begins taking on the self-appointed role as an observer of the season's events. However by the end of the third season and the beginning of the fourth 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 Tyranno 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!" Durring Jaden's Duel with Aster Phoenix, Syrus references a rather "Adult" line from American Pie in the english dub, but is cut off by Chazz. Syrus hasn't broken the fourth wall in a while.

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 was the next episode in the spin-off.

In the Japanese version Sho is voiced by Masami Suzuki. She also voiced Ghost Kotsuzuka, who called Bandit Keith "Aniki" as well.
