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, Nando, Jessie, Kenny, and even a fierce one with Ursula, her rival. There's also a disputable romantic interest she has in Ash because when characters accuse her of it she blushes.
Diamond and Pearl
Dawn made her debut in the first episode of Pokémon: Diamond and Pearl, Following A Maiden's Voyage!. In the next episode she met Ash's Pikachu after it had temporarily escaped from Team Rocket. Returning Pikachu to Ash would be how she met him and Brock. Dawn traveled with Ash and Brock through Sinnoh until Ash and Brock left for home after the Sinnoh League.
Dawn is a very confident person, when she makes a mistake she will often quickly recover and strive to do better. Sometimes she can be a little overconfident though, and it may cause her to make a mistake, like when she had her newly evolved Ambipom use swift. Despite this, Dawn is carefree, upbeat, cheerful and is always confident in her abilities, even from the beginning of her journey. Dawn will do whatever it takes to save her Pokémon when they are in trouble, much like Ash. Dawn will usually say the phrase, "No need to worry!", to which her mother views this as a cause to worry more. Dawn's mother, Johanna, gave Dawn her very first ribbon in the first episode and now Dawn keeps it with her as a good-luck charm. Her old friends for some mysterious reason (which Dawn keeps trying to hide) call her "Dee Dee" (Diamond Dandruff). In DP161 it was revealed that the reason for the name was due to her hair glittering (ピカピカ pikapika) after being shocked by the class pets in her kindergarten, Plusle and Minun. Due to the trauma from being teased by her entire class with the nickname, she is very reluctant to let others know the origin of the name.With her hair ruined, Kenny spread the word and soon she was teased by the nickname.
Dawn seems to be more fixated on her appearance then the other two main female characters Misty and May. In an episode, Dawn would refuse to show herself to Ash and Brock until she straightened out her bed hair. She will also brush her hair thoroughly before appearing on T.V. Dawn also seems to have some talent in designing, as she designed a series of outfits for the Hearthome Collection and Buneary's outfit.
In her first contest, Dawn makes friends with a talented Coordinator called Zoey. Dawn loses her accessory just before the contest, and after much panicking and searching, it is revealed that she had dropped it and Zoey had picked it up. After returning it to Dawn, Zoey goes on to win the contest. Dawn cries at her loss and after a quick word of support from her mother, Zoey talks to Dawn about how losing is just a lesson that you should learn from. Dawn promises that she will become just as good as Zoey one day, and at this a rivalry is formed between the two girls.
For a while, Dawn seemed to be on a losing streak, losing in the appeal round of her competitions two times in a row. Though learning that the Gym LeaderMaylene had similar problems and confidence issues she agreed to battle her in the episode Crossing The Battle Line!. Though she lost this battle, it motivated her to train harder and she did. She eventually would go on to win the Wallace Cup, defeating May in the process. From here on Dawn currently has three ribbons and is strongly pursuing her goal.
Her goal proceeded as she participated in her fourth Pokémon Contest in the episode 'Another One Gabites the Dust!'where Dawn faced a rather mean and arrogant girl named Ursula. After insulting her, the two coordinators developed a fierce rivalry. Soon enough, two girls faced each other at the finals where Dawn's Pachirisu barely managed to beat Gabite from Ursula though winning the battle. Dawn won the contest and so won her fourth ribbon. Now only one ribbon is keeping her away from the goal of participating in the Grand Festival and possibly fulfilling her dream of becoming the Top Coordinator
As she learns about the double appeals in the upcoming contest, Dawn is determined to create a new combination. At first she lacks of ideas, but soon develops a Ice-Fire combination idea consisted out of Mamoswine and Cyndaquil. While using Flame Wheel, Cyndaquil is trapped inside of the ice block. Dawn however fails to perfect her combo and it's not until her fifth contest in Daybreak town where she faces Ursula that she manages to use it successfully. With the help of Plusle and Minun, Ursula manages to make Dawn's hair glitter again embarrassing her in front of everyone. Dawn relives the flashback from the past, but soon finds encouragement as she orders one final combo from Cyndaquil and Mamoswine. Within Mamoswine's ice block, Cyndaquil manages to form an ice rocket powered up with a Flame Wheel from inside. The attack successfully collides with the little Plusle and Minun assuring Dawn her fifth and final contest ribbon and finally overcomes her trauma.
In episode 171 Dawn passes through a town where a Pokémon contest (Last one) before the Sinnoh Grand Festival is about to start. Dawn enters the contest as of everyone's surprise (especially Jessie) but the truth is that Princess Salvia, a girl who looks like Dawn, posed as Dawn and entered the contest with her Togekiss. Meanwhile, Dawn posed as the princess. Dawn was not suiting for this, as she had no princess-like qualities and also showed discourtesy, thus had major trouble portraying Salvia. However she managed to pull through without being discovered. During both Appeal and Battle Round the princess enters with her Togekiss and actually winning it. But Later she gives away the Ribbon to Jessie for her hard work and gives Dawn her Togekiss so that it may continue to participate in contests. Thus Dawn acquires a Togekiss to her Team.In episode 172 Dawn teaches her new Pokémon Togekiss about battles and to maintain elegant looks.
In episode 174 the grand festival begins. All the coordinators start-off against each other in the Appeal Round. During the First Round, Ursula uses two Eevees which were evolved into Flareon and Vaporeon, Nando uses Altaria and Kricketot, Zoey uses Gastrodon and Lumineon, Jessilina uses Seviper and Yanmega, Kenny uses Empoleon and Floatzel, Dawn uses Buneary and Cyndaquil and the Festival continues with others. Kenny's performance is flawed when his Empoleon's Flash Cannon hits Floatzel's Whirlpool which knocks Floatzel down. At the end of the day, the results are announced. Except Kenny, all of Dawn's rivals including Dawn make it to the Battle Round.
In episode 175 Dawn battles Ursula once again and after 5 minutes of intense battling Dawn defeats Ursula. After Ursula's defeat she admits that she is weaker than Dawn and the two go from rivals to best of friends upon leaving the hotel.
In episode 176 Dawn manage to reach the top 4 of the grand festival. There finds herself against to no other than Jessilina. In the end Dawn won and advanced to the final to face Zoey who beat Nando in the semi-finals.
In episode 177 the Sinnoh Grand Festival starts between Zoey and Dawn, they both showcase their skills as top coordinator; but as the time runs out, with only few points difference Zoey wins the title of Top Coordinator and the Sinnoh Ribbon Cup so she gets in the second place. She promises to her Pokémon that they will not stop trying until they reach the top.
In DP191, this is Dawn's last appearance as a main character. Upon returning to Twinleaf Town, Johanna informs Dawn that Paris from Hearthome City wants Dawn to model Buneary and the outfits she designed. Although Dawn was originally going to leave with Ash and Brock to go to Kanto, she decides that she will remain in Sinnoh.
Ash, Dawn, and Brock arrive at the port at Sandgem Town, where they are getting supplies. Dawn thanks Ash and Brock for all their help and wishes them luck in their futures, while Ash and Brock wish her the same. Ash and Dawn give each other one last high five before parting. As Ash, Brock, and Pikachu board the ship, Dawn feels very saddened and looks away as the ship leaves the harbor. Ash then calls out to Dawn, reciting her phrase "No Need to Worry! We'll meet again someday!". Dawn then brightens up and she and a tearful Piplup run out to the harbor and sadly wave goodbye to Ash, Brock and Pikachu as they sail away in the sunset. Piplup then jumps into Dawn's arms and give each other a big hug, knowing although Ash and Brock are no longer with them, they will always have each other.
In the Pokémon DP Special Episode 1, Dawn has been spending her time in Twinleaf Town since Buneary's photo shoot, trying to decide whether to pursue becoming a Pokéstylist or continuing contests. She visits Rowan's lab where she meets a new trainer, Cinco, who is about to start her journey. However, while she and Cinco are looking for Chimchar and Piplup, who got into a fight and ran off (like the first episode), they are attacked by wild Ariados. Piplup and Cyndaquil do battle against them, resulting in Dawn's Cyndaquil evolving into Quilava. Near the end of the episode, Dawn decides to continue to her journey to the Hoenn region.

Having run off from the lab in a dispute with Chimchar, Dawn finds Piplup trapped in a web and helps it out. Piplup & Dawn grew a close bond very quickly. Piplup can be described as a brat, but it truely tries its best in battles, despite the fact that its not the most powerful Pokémon. Piplup usually tries to show off his pride by taking the lead. Dawn tends to let Piplup stay out of its Poké Ball but does keep it in sometimes. In the final episode, Piplup is very upset when Ash, Brock and Pikachu return to Kanto, and cries while waving goodbye to them.
After having various Buneary attack her during her travels, Dawn came across another Buneary. Eager to add it to her team, she attempts to battle it and eventually succeeds and captures it.

It is a loving Pokémon, that is known to shock Dawn whenever it is happy, causing Dawn a Bad Hair Day. However, it has some powerful attacks including Spark so it is able to hold its own in battle.
After evolving from Piloswine, Mamoswine seems to be even more hot-headed and immediately charged at Ash & Co. With its powerful attacks such as AncientPower and Ice Shard, Mamoswine is the major massive powerhouse of Dawn's team. After it evolved, it had trouble obeying Dawn until Dawn managed to convince it to obey when she took care of it when it was injured. When it's not in battle, it has a habit of sleeping.
While Dawn was helping Professor Rowan to get some runaway Pokémon back, Dawn & her Pokémon got captured by a swarm of Ariados. In order to help, Cyndaquil evolved into Quilava and managed to use its massively powerful attacks such as Eruption to defeat the Ariados and protect its trainer.
After allowing a princess called Salvia to take her place in a Pokémon Contest, Salvia was kind enough to allow Dawn to have her Togekiss so that Togekiss can partake in Pokémon Contests, which Salvia herself is unable to do. Togekiss has many powerful attacks such as Aura Sphere that allow it to be able to be able to hold its own in battles as well as create dazzling appeals. On Normal Situations, it acts like the eldest Pokémon, just like a big sister to all of Dawn's other Pokémon.
Before evolving, Ambipom was originally Ash's Pokémon. However, since Ash met it, it has loved the idea of contests and not battling and was eventually traded to Dawn and evolved soon afterward. Through the training it received from Ash when it was an Aipom, Ambipom is one of the major powerhouses of Dawn's team, and with this and its love for Contests, it is likely to be used many times in Dawn's campaigns. After partaking in a Pokémon Ping-Pong Tournament, it learned it's true calling and after much consideration, decided to leave Dawn & Ash and stay training in Ping-Pong.
After hooking it while fishing, the strong Buizel managed to take out Pikachu, Piplup and Zoey's Glameow. This made all three want to get it. After rescuing it from Team Rocket, Buizel allowed Dawn to battle it in order to capture it, which she did. Buizel is a rather strong and arrogant Pokémon, the strength of her team. However, due to its arrogance, it is not above disobeying orders. Buizel was more into battling than contests. This led Zoey to ask Dawn if it was right to be in her team. After a trial, Dawn decided to trade Buizel for Ash's Aipom.
