In The Anime
In the anime, Johanna makes her debut in Pokémon Diamond and Pearl. She is Dawn's mother and a former Top Coordinator with a great reputation in the Sinnoh region. She is Dawn's inspiration for becoming a Top Coordinator. Johanna gives Dawn one of her Ribbons as a good luck charm when she leaves on her adventure.
Johanna is eager to see Dawn embark on her journey and reminds her early that she needs to become a great trainer in order to become a top Coordinator. Dawn frequently chats with Dawn, as well as Ash and Brock, through their travels in Sinnoh; she especially makes an effort to speak with Dawn after every Pokémon Contest.
Johanna's main Pokémon partner is her Glameow.
