Dawn (Crimson)

Dawn is the female player character in Pokémon Diamond and Pearl as well as Pokémon Platinum. If the player chooses Lucas, the male player character, Dawn will be Professor Rowan's assistant. She helps you by giving you items on your adventure and she does the Pokedex project with you. 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 and be polite. In the game, you will befriend others, such as the champion, and people you tag team with, like Bucky, before and after you beat the game. Dawn will be in possession of the other starter that wasn't chosen, the one which your starter will have an advantage against. i.e. if you have chosen Chimchar, she will have a Turtwig in her arsenal. The reason if your Lucas you don't battle her is because she has the disadvantage Starter Pokemon of you, as the same goes for Lucas.
