Agatha (Quartz)

Agatha is a member of the Elite Four in Kanto, who uses Poison-type Pokémon. She was Professor Oak's rival when they were young.

Kanto
Four trainers, the Kanto Elite Four, gather at a place. The old woman, Agatha, comments it has been some time since a challenger came to the place with eight Gym Badges and understands Lorelei's impatience. Lorelei promises she'll freeze him, while Bruno clenches his fists. Lance, however, wants to see how good the challenger is and warns others to prepare themselves. A trainer, who stands outside the building, promises she will be the best Pokémon trainer in the world by facing the Elite Four.

The challenger's Rhydon defeats Arbok. Agatha calls Arbok back, noting it is no surprise the challenger came thus far to victory. The challenger states it is exactly as she planned, though Agatha smiles, claiming the challenger would actually be collecting Pokémon for the Pokédex of her "old coot". The challenger smiles back, claiming she shouldn't compare her with the Professor Oak just because he's better than her. Instead, the challenger states completing the Pokédex is but a tool to grow stronger. Agatha is amused, as she opens the Poké Ball on her cane, sending Gengar out, who attacks.

Agatha battled with her Gengar against Red and his Dodrio. As Red later faced Lance, Agatha was most likely defeated by Red.
