Winona

Winona (ナギ Nagi) is the Fortee City Gym Leader, and holds the Feather Badge. She uses Flying-Type pokemon in her gym.

In Anime
Winona's first appearance in the anime was in the episode Who's Flying Now?. Just as in the game, Winona is the Fortree City Gym Leader, though in the anime Winona's Swellow is a shiny pokemon.

When Ash makes a visit to the Fortree Gym he discovers that Winona is not in the gym, but that she was at a local festival. Upon meeting her, Ash is still unable to battle her due to Team Rocket's interference.

The two battle in the next episode Sky High Gym Battle. Ash won the battle using Grovyle, Swellow, and Pikachu against Winona's Altaria, Pelipper and her own Swellow. When defeated, Winona rewarded Ash with the Feather Badge.

In Game
Winona first appeared in the main game series in Pokémon Ruby and Sapphire. She has the same Pokemon team that she used in the anime (Swellow, Pelipper, Skarmory and Altaria)

In Pokemon Emerald, Winona's team changes slightly during the rematches. She now includes a Tropius, Hoothoot and its evolved form, and Dratini and its evolved forms.

When the player defeats her, Winona will reward the player with the Feather Badge, and TM40 (Aerial Ace).
