Yu-Gi-Oh Poke Duel came to this game portal. This game is a mod for Pokémon Fire Red that replaces all Pokémon with iconic Monsters from Yu-Gi-Oh. All Gym Leaders, Elite 4 and Champion were replaced by Yu-Gi-Oh characters. NPCs throughout the region have their dialogue updated to make references to the Yu-Gi-Oh anime and trading card game. Gym Leaders/Elite Four use 6 monsters (from 3rd gym onwards).
