Jean Jean is the leader of Team Unicorn . He is a cunning strategist and tactician , from planning for Crow to crash into Breo just to get a glimpse at Yusei ' s Deck to eagerly awaiting for Team 5D ' s to be disqualified from the WRGP after Jack crashes and would either lose on a technicality if he couldn ' t get to the pits in time or if someone helped him . Biography . History . While gathering members to create an unbeatable team , Jean ran into Andre Duel ing someone and losing . Jean had noticed that Andre could have won if it wasn ' t for his weakness . He then offers him a spot on his team and Andre accepts . After that , the two began traveling around , looking for a third member to join their team . While tuning up one of their Duel Runner s , the two meet Breo . He tells them to leave as it is " his " practice spot , but they refuse by stating that it is a public place . Breo challenges them to a Duel and is defeated by Jean ( unseen ) . Afterwards , Jean tells Breo he is a powerful opponent and that he has potential , asking him to form a team with himself and Andre . Breo ' s girlfriend then asks Jean if she could go out with him but he rejects her saying he dislikes women who aren ' t serious . During all the tournaments that follow , he ' s never had to Duel , since Andre has been able to handle it all on his own . Pre - World Racing Grand Prix . Jean is at the opening ceremonies for the WRGP along with his teammates . They all introduce themselves to Team 5D ' s . Later , he is practicing with the rest of Team Unicorn when Crow crashes into Breo . He is infuriated and demands that there be a punishment . The three decided to have them make up for it by having Yusei Duel Andre , to which he accepts . He and Breo then discuss their plan to watch Yusei Duel and learn how he Duels . As he watches , he is impressed by Yusei ' s Dueling skills . World Riding Duel Grand Prix . After the opening ceremonies , Team Unicorn prepared their team for their match . Jean would be the " Last Wheeler " to Duel . He watches Andre ' s Duels with Jack and Akiza and is still impressed with him . He then watches him Duel with Yusei after Andre defeats the two . Jean signals Andre to lose so that Breo could take over and use his Deck Destruction strategy to win . However , Jean didn ' t count on Yusei defeating Breo , so Jean happily takes over and Duels Yusei to finish him off . Despite Breo having milled nearly all of Yusei ' s Deck , Jean changes his mind about defeating Yusei with Deck Destruction , and believing that it was the best Duel he has ever had , attacks Yusei ' s " Rapid Warrior " with his monster , even though Yusei was Deckless and would lose if Jean simply ended his turn . However , Yusei outsmarts Jean ' s moment of weakness , and uses " Stronghold Guardian " to effectively counter Jean ' s attack and reflect enough damage to defeat Jean . Although he had lost his Duel , Jean was satisfied with the result , and his teammates later approved of his actions during the Duel and did not mind about their incidental loss . Team Unicorn ' s next Duel was against Team Catastrophe , but during the Duel both Andre and Jean crash , due to the use of the Shadow Card " Hook the Hidden Knight " . Jean is later seen at the hospital , when Breo leaves Yusei to check on him . Decks . Jean plays a Beast Deck with an emphasis on Beatdown stratagems . His trump card is " Lightning Tricorn " . Each member of Team Unicorn possesses a key Synchro Monster which can be considered representative of its user . Jean would be represented by " Lightning Tricorn " due to its being the strongest Unicorn Synchro . Its ability to Special Summon either " Thunder Unicorn " or " Voltic Bicorn " represents Jean ' s appreciation of team work and unity .
