Ep 30. Guarding the Guardian of the Mountain!

Ash and his friends continue their journey to the White Ruins, where they are excited to uncover the mysteries of the legendary Pokémon Reshiram. Along the way, they stop in a small town where they meet a young girl named Brycen, who is the gym leader of the town's Pokémon gym.

Brycen invites the group to join him on a hike up the nearby mountain, where they hope to catch a rare glimpse of the legendary Pokémon Cobalion. On the way up the mountain, they encounter many obstacles, including steep cliffs and treacherous terrain.

As they near the top of the mountain, the group comes across a beautiful shrine where they meet the Guardian of the Mountain, a fierce and powerful Pokémon named Terrakion. Terrakion warns them of the dangers ahead and asks them to leave the mountain immediately, but Ash and his friends insist on staying and exploring the area.

Brycen tells the group about his past encounter with Terrakion and how he was able to earn its trust. He explains that Terrakion is very protective of the mountain and its inhabitants and that it will stop at nothing to protect them from danger.

As they explore the mountain, the group encounters a group of trainers who are trying to capture Terrakion. Ash and his friends team up with Brycen to protect Terrakion and prevent it from being caught by these ruthless trainers.

The battle between Terrakion and the trainers is intense, but with the help of Ash and his friends, as well as Brycen's powerful Pokémon, they are able to defeat the trainers and save Terrakion.

Terrakion thanks them for their help and tells them that they have earned its trust. The group continues on their journey, now with a newfound respect for the power and importance of the legendary Pokémon in the world of Pokémon.
