Johto League Silver Conference, she returns to Cerulean Gym and resumes her duties as the Gym Leader while her sisters leave for a cruise around the world. As such, she is not featured as a main part of the
Advanced Generation series and only appears in five episodes and in
The Mastermind of Mirage Pokémon, a 10th Anniversary special episode event. However, she is often a central character in the
Shūkan Pokémon Hōsōkyoku, and
Pokémon Chronicles. In one of her few appearances in the
Advanced Generation series, her Togepi evolves into
Togetic. Misty releases Togetic after it chooses to stay behind to defend the Mirage Kingdom. After Ash finishes competing in the Hoenn League, he returns home to
Pallet Town to find Misty waiting for him. However, she isn't the only one to rejoin Ash, as May, Max, and Brock join him as well for the Battle Frontier challenges. She remains in his team for two episodes, and shortly after returns to her gym. Although she might be returning in Sinnoh and will join Ash,Brock and Dawn for the rest of Sinnoh. And might be bringing her Marill along with her and will be entering in Contest with Dawn with it.
