His quotes and expression from the episode 39 is sometimes used as a meme:
Kachidoki: "イダテンの効果発動! このカード以下のレベルのモンスターとバトルする場合、相手モンスターの攻撃力は0となる!" (I activate Idaten’s effect! When this card battles against a lower level monster, that monster’s attack becomes zero!) Yuuya: "エクシーズモンスターはレベルを持たない。よって効果は無効。" (Xyzmonsters do not have levels. Therefore, that effect is negated.) [*1] Kachidoki: "何? レベルを持たないならレベル0ではないのか!?" (What? If it doesn’t have levels, doesn’t it mean that its level is 0?)
([*1]: Technically speaking, the effect cannot be activated in the first place.)
