Yu-Gi-Oh!

A Japanese Manga created by Kazuki Takahashi. It has spawned a franchise that includes multiple anime shows, a trading card game and numerous video games. Most of the incarnations of the franchise involve the fictional trading card game called Duel Monsters, where each player uses cards to "duel" each other in a mock battle of fantasy "monsters". The Yu-Gi-Oh! Trading Card Game is the real world counterpart to this fictional game on which it is loosely based.
