Moon

Moon (Japanese: ムーン Moon) was the former Champion of the Alola Region. She gave up her position as Champion to pursue other careers. Although there is no challenger who has defeated her yet, she would still come over to the League and battle. A running joke is that she tries to lose on purpose, but always ends up winning by pure luck.

During the events of USUM
Moon is a sweet and timid girl that used to be a pushover most of the time. She tends to apologize for almost every single thing she does, even if the blame is not directed towards her. Due to her nervousness and anxiety, she used to stutter her words when communicating with others.

Current
As of lately, Moon rarely ever stutters. The only times where she does is when she gets surprised. The reason being is that she gained a lot of confidence months after the events of Necrozma and the Ultra Beasts. Because of this, she slowly developed an aggressive, yet daring side.

She tends to call herself "your friendly neighbourhood controversial child" due to her having a strange sense of humour and constantly playing a sweet girl act to cover it up.

Childhood
Moon was born in Celadon City in the Kanto Region and has lived there with her mom until they moved to Alola. Her birth was completely accidental and due to this, Moon was often referred to as a “mistake child” by other adults. The only time where she has met her dad was on her first day of kindergarten. The reason as to why her dad was never around was because he did not want to have anything to do with her because she was a "mistake". Another reason was that he has another family to take care. In short, Moon has half siblings that she has never met.

When growing up, Moon did not make a lot of friends and was bullied everyday. The reasons were her voice was so high pitched that she sounded like a Pichu and that the other children's parents have told them that she was an illegitimate child. When she no longer had the restraint to endure the torment the bullies have given her, out of pure anger, she punched one of the bullies in the face.
