In the game Yu-Gi-Oh! Nightmare Troubadour, the card lore for this card is actually "A winged dragon brought back to life by means of modern technology". This was actually the first lore in previous games.
Despite being referred to as a mechanical alligator, both its OCG and TCG lores refer it to as an animal that is NOT an alligator; OCG's a winged dragon, and TCG's a pterodactyl. Also, its name, when translated from Japanese is a "Cybernetic Wyvern".
It also bears a strong resemblance to "Alligator's Sword", whose OCG name is "Wyvern Warrior".
