After returning home and reuniting with Cynthia, Yong brought her to a mountain near Pallet Town to find an unusual Pokémon he hoped to catch. The pair began climbing toward it, though Yong had not yet revealed what it was.

• Yong led Cynthia up the winding mountain path to search for the Pokémon.

Yong and Cynthia explored Mount Miacha, where the wild Onix grew increasingly enormous, as Yong searched for a giant Onix to become a companion for his Steelix. As a powerful disturbance approached from deeper in the valley, Yong faced east, hoping the giant Onix he sought had finally appeared.

• Yong and Cynthia traveled into Mount Miacha, where Gliscor defeated wild Pokémon and they entered a valley filled with Onix.

• Onix grew angry at being ignored, and Yong turned to face her and prepare to earn her respect.

• Onix thrashed in pain and crashed into the surrounding rock walls as Yong ordered Excadrill to attack repeatedly with Rapid Spin and Metal Claw.

Yong and Cynthia entered a secluded valley after Yong caught its Giant Onix, hoping to discover the valley’s origins. They found what appeared to be ancient ruins, and Cynthia began studying the worn markings on a central bluestone slab.

• Excadrill defeated the Giant Onix with Smart Strike, and Yong caught it in a Heavy Ball.
• Yong recalled Excadrill and went with Cynthia to explore the valley where the Giant Onix had come from.

They planned to establish a research institute and Pokémon wildlife park on Mount Miacha, then parted with Cynthia preparing to return to Celestic Town while Yong stayed to begin his challenge.

After leaving Excadrill to secure Mount Miacha and gather local Pokémon, they flew toward Saffron City to begin the next stage.

After Cynthia encouraged Yong to keep building toward the top, he returned to Pallet Town and stayed at Professor Oak's Laboratory while planning a laboratory on Mount Miacha.
