Red-Eyes Black Dragon (Monster World)
Red-Eyes Black Dragon appeared as a Monster World figure in the title page for Yu-Gi-Oh! Duel 52: "Millennium Enemy 3: The Fumble of Doom", but did not feature in the story and was unnamed at the time.
It did not re-appear until twenty seven chapters later, where it was a Duel Monsters card, "Red-Eyes Black Dragon", rather than a Monster World piece.
