Lady Selphy (Japanese: アキホAkiho) is a rich girl who debuted in Pokémon FireRed and LeafGreen. She offers expensive items in exchange for showing her Pokémon registered in the player's Pokédex within a limited period of time.
In the games
Selphy lives in a house in Resort Gorgeous. However, her house is empty when the player first arrives, and the player needs to find her in Lost Cave before doing anything else. After finding her, she will fight the player with her two Persian.
After her defeat, she returns to her house, where she and her butler Sebastian (Japanese: セバスチャンSebastian) live. After that, she will ask the player to show her a specific species of Pokémon. If the player does, she gives an expensive item. However, if the player takes more than 250 steps before showing her the Pokémon, she will be disappointed and ask for a new Pokémon to see. She can ask for any Pokémon registered as seen or caught in the player's Pokédex.
