Cheryl (Japanese: モミ Momi) is a Pokémon Trainer from Sinnoh. She specializes in Pokémon with high HP.
In the games
Cheryl is one of five Trainers who can join with the main character during an event in Pokémon Diamond and Pearl. Later, she can join the player in competition at Sinnoh's Battle Tower. She first appears in Eterna Forest. She asks the player to join her because she's afraid she might run into Team Galactic. Her Chansey is good at using restoration techniques like Refresh and Softboiled, but it is not good at offense.
In Platinum, she will also give the player a Soothe Bell at the end of the Eterna Forest.
