Dawn is the female player character in Diamond, Pearl and Platinum. If the player chooses Lucas, the male player character, Dawn will be Professor Rowan's assistant. She helps the player by teaching them about important elements in the game, such as item shops and Pokémon Centers, how to catch Pokémon, and also gives items during the adventure. She is also part of the Pokédex project. The other blond haired rival will fight you throughout the game, but Lucas/Dawn (depending on the choice of being a boy or a girl) will only assist you politely.
