Lucky Lucario I/VS. Lucario I (Japanese: VSルカリオI VS. Lucario I) is the 379th round of the Diamond & Pearl chapter in the Pokémon Adventures manga.
At Iron Island, Riley explains about the island and takes Diamond to a place to train. Diamond's first training is a battle with Riley's Lucario as a 3 on 1 battle. Lucario defeats Lax, Don, and Tru by using Aura Sphere. Riley explains after the battle that Diamond's party has very good defense, but is still weak in speed. He takes Diamond to the cave and says that Diamond should start training there. He says that Diamond must travel trough the cave at least five times and explains that each time there will be wild Pokémon to battle.
The scene then cuts to Diamond traveling in the cave and getting attacked by a Steelix. After battling it, Riley starts talking about Team Galactic's plan. At the end of round, Riley says that Diamond should hurry because he has only three days left.
- Diamond starts his special training with Riley having a 1 on 3 battle and losing.
- Diamond receives his second task from Riley; to make his way down to the lower part of the cavern, battling powerful wild Pokémon en route.
