Dawn

Dawn is a young, blue-haired Pokémon Coordinator who traveled through the Sinnoh region along with Ash and Brock. Dawn started her journey at the age of 10, honing her skills as a Pokémon Trainer and focusing on becoming a Top Coordinator like her mother, Johanna.

She's notable for her confidence, even when things are not going well. She has learned a lot throughout her travels and battles and can get very emotional when it comes to winning or losing in a contest. Throughout her Sinnoh travels, she has developed rivalries with many coordinators such as Zoey (her main rival, albeit a friendly one), Nando, Jessie, Kenny, and Ursula.

Personality
Dawn is very confident in her abilities, though not to the same extent as Ash. She often gets emotional when she loses, and Ash and Brock often helped her to cope with that. When she lost two contests in a row, not managing to get through the first round of appeals, she became very depressed. However, she regained her confidence after she won the Wallace Cup, along with a new found sense of maturity. She is also very sensitive and supportive of her friends. A clear example of that occurred when she worked on a cheerleading recital to help Ash feel better after he fell into depression following his humiliating defeat at the hands of his bitter rival Paul. She also appears to be quite quick-tempered sometimes.

Trivia

 * Dawn's bike was destroyed by Pikachu's Thunderbolt, a sort of ongoing gag that has been used with Misty and May, but wasn't angry at Ash or Pikachu for it due to unfavorable circumstances (attacked by Team Rocket) on their end. This ended with Iris, who started the gag of being shocked by Pikachu directly.

 * Both Hikari and Dawn mean some type of light.
 * As revealed in DP161, Dawn's nickname Pikari/Dee Dee is tied with her fear of Plusle and Minun.
 * Dawn is the first main character other than Ash to see a Legendary Pokémon right at the beginning of her journey with her destined Pokémon. Ash saw Ho-Oh with Pikachu on his side while Dawn saw Mesprit after saving Piplup.
 * Ash later encounters Azelf during the Wallace Cup, with the subsequent conversation seeing Zoey reveal herself as being from Snowpoint City.
 * Dawn is the first of Ash's companions to have caught an Electric-type Pokémon, Pachirisu.
 * Dawn's personality reflects that of the emotion Pokémon, Mesprit.

 * Dawn became famous for winning the Wallace Cup.
 * Dawn has battled two Gym Leaders in the anime: The first was Maylene and the second was Cilan.
