Chazz Princeton Chazz Princeton , known as Jun Manjome ( , " Manjōme Jun " ) in the Japanese version , is an arrogant Duelist who serves as one of Jaden Yuki ' s rivals throughout the series . Chazz is considered Jaden ' s main rival in the same effect that Seto Kaiba is the rival of Yugi Muto . The two have Dueled one another a total of seven times throughout the seasons of the anime . Through his evolution , he goes from being a Duelist who only respected powerful cards to a Duelist who believes that there can be effectiveness in any card . He becomes a marked threat after becoming the North Academy representative but after that becomes more and more a comic relief character . In the manga , Chazz originally serves much the same purpose as in the anime , but later becomes a . Design . Chazz ' s character design was overseen by .

Voice and mannerisms . When he becomes the top of the North Academy , he gains the catch phrase " Chazz it up , " while in the original version of the series it is " ichi , jū , hyaku , sen , Manjōme - sandā " ( 一 、 十 、 百 、 千 、 万丈目サンダー meaning one , ten , hundred , thousand , Manjome Thunder ) , which serves as a pun given that the " Man " portion of his surname is the symbol for the number ten - thousand , and is preceded by the numbers one ( ichi ) , ten ( jū ) , hundred ( hyaku ) , and thousand ( sen ) . In the latter case , he also acquires the moniker " Manjome Thunder " ( 万丈目サンダー ; " Manjōme Sandā " ) . Due to his insistence that he be addressed respectfully , he often finds himself correcting others who merely call him " Manjome " by saying " Manjōme - san da ! " ( " It ' s Manjome - san ! " ; " - san " being a Japanese honorific ) . The students of North School , however , mistook the title as " Manjome Thunder " ( " sandā " being a Japanese pronunciation of the word " thunder " ) , and the name stuck upon his return to Duel Academia . In the English version , he often refers to himself in the third person as " The Chazz " , and at times uses the phrases " It ' s go time " and " You go bye bye " .

He hated Jaden so much that during Jaden ' s tag - team Duel against the Paradox Brothers to determine whether or not they are expelled , he watched with a malicious smile on his face , waiting for Jaden to lose and be expelled . After losing his Duel to Jaden , he left Duel Academy and ended up in North Academy , whose entrance exam required the Duelist to find 40 cards to make a makeshift Deck . From this experience , he learned to appreciate any and all cards , weak or powerful , which have the potential to be useful . After losing to Jaden yet again , he returns to Duel Academy but has to be a Slifer Red . After Duel Academy ' s " takeover " , Chazz had to again make a makeshift Deck of useless cards and still won .

Despite having access to rare cards provided by Vellian Crowler , Chazz is defeated by Jaden Yuki early on in the first year . He is then overwhelmed by Bastion Misawa , and eventually became so dispirited and confused from his losses that he left Duel Academy to enter North Academy .

Acting as North Academy ' s representative Duelist , he was defeated again by Jaden , but realized the errors of his ways and was finally able to take charge of his own life ( during the Duel , Chazz tried to win on his own by using the Deck given to him from North Academy for the Duel as opposed to the Deck that his brothers wanted him to use ) . He was welcomed back to Duel Academy , but forced to restart his studies out of the Slifer Red dorm . From the ordeal , Chazz obtains a spirit partner in the form of " Ojama Yellow " , who Chazz finds annoying .

Because of this , all the Slifer students , convinced he did like the Slifers , began rooting their appreciation despite his protests : in turn , Crowler announces Chazz had chosen to stay in Slifer , much to Chazz ' s distain . As a result of this , Chazz began renovating the dorm ' s interior to build a luxurious room just for him : this caused him to room with Jaden and Syrus until Tyranno Hassleberry moved in .

Also it ' s revealed that as a Slifer Red Chazz acts more like a slob because when he was still his old self he used his old black jacket to wipe up food from the cafeteria . It ' s also revealed that unlike he is made to believe Chazz harbors a great deal of dislike for the color white .

Chazz goes on to Duel the Academy ' s strongest student , which happens to be Jaden .

Chazz ' s Deck changes the most of any " Yu - Gi - Oh ! " character , evolving and growing as his circumstances and outlook on Dueling shift . His initial Deck is a Hell Deck , consisting of powerful Fiend and DARK monsters , including " Chthonian " monsters . This Deck isn ' t seen at length but appears to have several control elements to it , " Chthonian Polymer " and " Chthonian Soldier " turning an opponent ' s powerful monsters against them , and " Mefist the Infernal General " and " Helpoemer " discarding cards from the opponent ' s hand . During a school exhibition Duel , Vellian Crowler gives Chazz the " VWXYZ " series with the intent for him to humiliate Jaden . These cards focus on combining and fusing together to form powerful Fusion Monster s . Chazz draws the needed monsters into his hand with " Magical Mallet " , then summons them to the field quickly by using " Frontline Base " , or discarding them to be revived . When he arrives at North Academy deprived of his Deck , Chazz is forced to scavenge cards from the grounds to make a new Deck . This Deck relies on a One Turn Kill strategy , such as a combo of " Inferno Tempest " , " Chaos End " and " Return from the Different Dimension " . At this time Chazz acquires " Ojama Yellow " as his spirit partner . As a prize for becoming North Academy ' s top Duelist , Chancellor Foster grants Chazz the " Armed Dragon " series . This Deck focuses on evolving the " Armed Dragon " monsters into stronger forms and using their effects to destroy opposing monsters by discarding cards from the hand . When Chazz ' s brothers attempt to buy out Duel Academy , Chazz is forced to Duel Slade using a Deck of monsters with only 0 ATK . He gathers cards other students have thrown into the Reject Well and forms a largely defensive Deck , protecting himself with monsters with high DEF and limiting Slade ' s attacks with " The Dark Door " . Chazz also acquires " Ojama Black " and " Ojama Green " , completing his " Ojama " trio , and beginning to make regular use of them in all future Decks . At this point for much of the rest of the series , Chazz combines all his previous Decks together , interchangably using his " Ojama " , " Armed Dragon " or " VWXYZ " cards . He uses a Power Deck that is continually supplemented with more and more support cards for the themes , largely using his " Ojama " cards as support for his " Armed Dragon " or " VWXYZ " cards , such as with " Ojama Ride " . While serving Sartorius , Chazz adds the " Beetron " cards to his Deck , along with " White Veil " and " Infernal White " . Sartorius later grants him a " White Knight " Deck centering on " White Knight Lord " . Unlike previous Deck themes , Chazz does not keep the " White Knights " once he leaves the the Society of Light , though he still makes brief use of the " Beetron " cards . In the manga , Chazz uses a Dragon Deck , with his signature card being his Spirit Partner , " Light and Darkness Dragon " .
