Agatha/Anime/Pokémon Generations

Agatha appeared in The Challenger, where she was first seen talking about, the first in a long time to collect eight Gym Badges, with the rest of the Kanto Elite Four. Later, she was the third Elite Four member challenged by Blue. After her was defeated, Agatha admitted to Blue that she had expected him, as the grandson of Professor Oak, to focus on completing the Pokédex, but Blue responded that, for him, filling the Pokédex was just a tool to become stronger. Blue managed to defeat Agatha and her off-screen, allowing him to move on to Lance's room.
