Nearing Blackthorn City, Ash, and his friends found Clair's Dratini and Gyarados. Team Rocket snatched the Dratini, however, and Clair gave chase. During the ensuing battle, an electric shock was heading straight for Dratini, but Clair jumped in front of it. Dratini witnessed its Trainer's devotion and evolved into a Dragonair to stop Team Rocket. Clair performed a ritual to purify the legendary Dragon Fang at Riverhead Falls. Afterward, Clair accepted Ash's challenge for a Rising Badge.
Ash and Clair began their Gym battle. Clair quickly gained the upper hand, but the fight ended when Team Rocket stole the Dragon Fang. Everyone chases Team Rocket into the Dragon Holy Land, where Team Rocket tricked a Dragonite into helping them. Liza and Ash's Charizard arrived on the scene, and they calmed down the raging Dragonite and put out the fire that threatened the Dragon Holy Land.
Clair and Ash then had their rematch. Clair called on her Kingdra, but it was left exhausted by its confrontation against Ash's Snorlax, knocked out by an Ice Punch. Gyarados defeated Snorlax by paralyzing it with a Dragon Breath attack. Pikachu's speed and super-effective Thunderbolt attacks helped him defeat Gyarados. Dragonair took out Pikachu and then faced off against Charizard. The round was initially in Clair's favor until Charizard managed to grab a hold of Dragonair and defeat it with a "Flaming Seismic Toss" combination, thus earning Ash his final Johto League Badge, the Rising Badge. Clair informed Ash that the Silver Conference will be in Silver Town, located at the foot of Mt. Silver, in three months.

Clair came to Cave Island in the Decolore Islands to hunt for a Shiny Druddigon. She bumped into Ash and his friends, revealing that she caught the Dragonite from the Dragon Holy Land, which later had a fight with Iris's Dragonite after the latter crushed a flower. The Druddigon she was searching for went on a rampage on the island, but she was able to calm it down before it joined her team. Clair visited Iris's hometown, the Village of Dragons, before meeting with Drayden. Before departing, Clair and Iris agreed to battle each other the next time they met.
After her travels with Ash, Iris journeyed to Blackthorn City for her promised match. Clair first took Iris to visit the Dragon Holy Land so she could help calm down a Gible that was damaging the city. Iris's Dragonite went up against Clair's Shiny Druddigon and lost the battle. Clair thanked Iris and told her that her ambition was vital to becoming a Dragon Master.
