Chancellor Foster forgets to take the " Armed Dragon " Deck back after Chazz opts to remain at Duel Academy ( in the dub this line is changed to him bemoaning the fact that he didn ' t get a kiss from Ms . Dorothy ) . Despite this , Chazz keeps the cards and the issue is never brought up again . It is around this time in the original version that he debuts his nickname " Manjoume Thunder . " The name is a pun in Japanese , but was considered untranslatable . The chant is simply changed to " Chazz it Up " in the dub . 0 - ATK .

Some of the cards from his " Chthonian " Deck were featured in the opening theme and also discard ed via card effect s .
