During the battle, both sides Gigantamaxed their Pokémon, with Pikachu even managing to land a couple hits on Charizard, but in the end, Pikachu was defeated. Beforehand, Leon gave Ash an explanation of how Dynamaxing and G-Max Moves worked and gave him his own Dynamax Band.

The next day, Leon approached Ash and Goh at the Wyndon Pokémon Center and accepted Ash's earlier request for a battle. He gave Ash advice that allowed him to defeat Drednaw before properly introducing himself to them. Leon saw Ash battling a Gigantamax Drednaw with his Pikachu and noticed that he had Gigantamaxed without a Dynamax Band. Shortly after the battle with Lance, in The Climb to Be the Very Best!, where Leon heard a commotion outside the stadium and went to see what was happening. After a hard-fought battle, Leon emerged victorious, making him the Monarch of the World Coronation Series.

Leon debuted in Flash of the Titans!, where he had a bout against Lance in the finals of the World Coronation Series at Wyndon Stadium, using his Charizard to go up against Lance's Gyarados. On his journey, Leon went through the Pokémon League of Galar undefeated, and eventually reached the top spot among the Masters Eight of the World Coronation Series. In Sword and Shield: "From Here to Eternatus!", Rose reveals that his goal with this was to guide Leon so that he would become the hero of Galar, and be able to control Eternatus.

But, Leon's closeness to Rose ended up driving Sonia away from him, which made the two go their separate ways over time. As revealed in Toughing It Out!, Rose was responsible for inserting Leon into the world of competitive Pokémon battles. In this period, Leon met more people and knew more about Pokémon. In his first victory in battle, it was evident that Leon had a natural gift for being a great Trainer. He wound up losing to her, but still found battling exciting and decided to devote his life to it. Sonia and Leon traveled together when they started on their journey, where Leon shortly after had his first Pokémon battle against Sonia herself. During this period, Leon found a Charmander that would become his first Pokémon and what motivated him to go on a Pokémon journey. Due to having to take care of his family for a long time, she was his only friend and taught Leon the concepts of a Pokémon battle.
