Ep 31. The Aura Storm!

Ash and his friends decide to take a detour on their journey to add a new Pokémon to their team. They come across a mysterious village where they learn about the legend of the Aura Guardian, a powerful trainer who had the ability to control the mystical aura energy.

As they explore the village, Ash and his friends meet a young girl named Korrina who is on a quest to become the next Aura Guardian. She tells them about her grandfather who was the previous Aura Guardian but had gone missing. They all decide to help Korrina in her quest and set out to find clues about the whereabouts of her grandfather.

Their search takes them to a remote mountain where they encounter a powerful and mysterious Pokémon. Korrina learns that this Pokémon is the key to unlocking the aura energy and decides to challenge it to a battle. However, the Pokémon proves to be too powerful for Korrina and her Lucario, and they are soundly defeated.

Undeterred, Korrina begins to train with Lucario and tries to harness the power of aura energy. Meanwhile, Team Rocket has also arrived on the scene and is trying to capture the powerful Pokémon for themselves. Their nefarious plans are thwarted by Ash and his friends, who team up with Korrina to protect the Pokémon and the village.

As Korrina's training progresses, she discovers that her grandfather is still alive and being held captive by Team Flare, a mysterious organization with nefarious intentions. Korrina, Ash, and their friends set out to rescue her grandfather and stop Team Flare from using the aura energy for their own purposes.

The final showdown takes place at a hidden temple where Team Flare has set up their base. Korrina, Ash, and her grandfather confront the villainous group and engage them in a fierce battle. The fate of the aura energy and the village hangs in the balance as the two sides clash.

In the end, Korrina successfully masters the aura energy and becomes the new Aura Guardian. With the help of Ash and their friends, she defeats Team Flare and restores peace to the village. Korrina and her grandfather are reunited, and she thanks Ash and his friends for their help. With their mission accomplished, Ash and his friends resume their journey, knowing that they have made a difference in the world of Pokémon.
