Cynthia (シロナ ?, Shirona in original Japanese language versions) (Korean:난천-Nancheon) is the league champion of the Sinnoh Region, as well as the first female league champion in the Pokémon video game series (other than the female protagonists). All of her Pokémon are female, except for her Lucario. Her arsenal consists of Milotic, Roserade, Garchomp, Spiritomb, Gastrodon, and Lucario. Due to the Pokedex additions in Pokemon Platinum, her Gastradon was replaced with a Togekiss.
She helps the player with several odd predicaments throughout the game, such as alleviating the headaches of a group of Psyduck. Her grandmother is the elder of Celestic Town, and she has a strong interest in Pokémon mythology. She first meets the player to give him or her the Hidden Machine for Cut. She says that when she was younger she traveled around with a Pokedex for Professor Rowan.
