Ep 22. Beyond the Rainbow!

While Ash and his friends are heading to the next town, Pikachu discovers a Rainbow Stone, a special gem that is said to have the power to make rainbows appear. As they examine the gem, a woman named Nicolette appears and tells them about the history of the Rainbow Stone. She explains that long ago, a Pokémon named Hoopa carried a Rainbow Stone with it wherever it went, and whenever it used its powers to transport people and things, rainbows would appear in the sky.

Nicolette also tells them that a man named Gurkinn, who has a close relationship with Hoopa, has been trying to locate all of the Rainbow Stones in the world. The group decides to accompany Nicolette to find Gurkinn and learn more about the Rainbow Stones.

Along the way, they come across a group of Pokémon trainers who are experiencing strange weather patterns caused by a malfunctioning weather machine. Ash and his friends help to fix the machine, but they soon discover that it was stolen and tampered with by a man named Millis Steel, who is searching for the Rainbow Stones.

Millis believes that the Rainbow Stones can lead him to a mythical Pokémon named Hoopa, and will stop at nothing to find them. Ash and his friends team up with Nicolette and set out to find Gurkinn and the Rainbow Stones before Millis can get to them.

As they journey through a treacherous mountain pass and encounter wild Pokémon and dangerous obstacles, they eventually reach Gurkinn's dojo where they are met with a surprise. Gurkinn challenges Ash to a battle and reveals that he possesses a Rainbow Stone himself.

After an intense battle, Ash emerges as the victor and Gurkinn agrees to let him and his friends learn more about the Rainbow Stones. The group is amazed to discover that the Rainbow Stones have the power to create a portal to another dimension, where they meet Hoopa, who is thrilled to reunite with his friend Gurkinn.

However, their joy is short-lived when Millis and his henchmen arrive and attempt to steal the Rainbow Stones. In a dramatic battle, Ash and his friends team up with Hoopa and Gurkinn to defeat Millis and his Pokémon and protect the Rainbow Stones.

As the episode comes to a close, Hoopa bids farewell to Ash and his friends, promising to always be there for them whenever they may need him. The group continues on their journey, with newfound knowledge and excitement for the adventures that lie ahead.
