Some cards have been released in the TCG with shortened or abbreviated names. A major reason for this was that the names were too long unabbreviated, and Upper Deck Entertainment had not yet figured out the smaller card name font for long names, but other reasons include stylistic choices and occasionally because the card name was also abbreviated in the OCG.

• "T.A.D.P.O.L.E." may stand for something in English, as its Japanese name ("Otamajakushi", 悪(お)魂(たま)邪(じゃ)苦(く)止(し)) is a pun on the Japanese word for "tadpole" ("otamajakushi", 御(オ)玉(タマ)杓(ジャク)子(シ)): "o" (悪(お)) = "evil", "tama" (魂(たま)) = "soul", "ja" (邪(じゃ<)) = "vice", "ku" (苦(く)) = "pain" and "shi" (止(し)) = "stop"
