Bonnie Kaji

Bonnie Sylvia Kaji is from Lumiose City in the Kalos region. She previously traveled with Ash, Alain, and Dawn in Kalos while they searched for the first two Plates of their journey. She's the little sister of Clemont Kaji. Her main Pokémon is a Dedenne.

Present
After running into her older brother, Clemont, the Mokusetsu (Ash, Alain, and Dawn) were invited to stay with her family while they were in Lumiose City for their journey. It was okay, since her family saw Alain on the news recently, explaining the objective of his group.

After their stay ended, Bonnie and Clemont followed them, revealing that their father, Meyer, had allowed them to travel with them a bit longer. They remained with the Mokusetsu through the journey for the first Plate, Shizuku, and were there when they encountered Serena and tried to return her home.

After the fight for the second Plate, Ikazuchi, Bonnie was caught by the Tekiyoku and was kidnapped, similar to what happened with Serena when she was younger. They took her to a lab in Geosenge Town to use her for experiments with the Science Division.

Upon arriving there, they locked her in a room with steel bars, while they left to get things for the upcoming experiments. They returned briefly to give her a substance meant to induce extreme sleepiness, which was supposed to take a while to have an effect. They left again. While they were gone, Bonnie freed herself with some bobby pins given to her earlier by Shauna.

She went outside, which was very foggy. After wandering around trying to find where to go, she became sleepy as the experiment from earlier was taking effect. She fell down asleep and unconscious. Ash ended up finding her and brought her back to the group. Clemont took her home, where things went back to normal.

Personality
Bonnie's pretty quirky and full of pep and can talk for quite a while at a time. Oftentimes, she'll bicker with her older brother, Clemont, constantly annoying him, usually by trying to get in his business while he's doing science-related stuff.

Despite that, she's loving of her big brother and wants to do more things that he does. She wants to be more involved with things her young age currently prevents her from doing, such as being a Manipulator.

General
She has a Dedenne, which she befriended ever since she was younger. It was owned by Clemont, but once she turned 10, Clemont gave it to Bonnie to officially own. The Dedenne is usually traveling outside of its Poké Ball.

Naming

 * Her first name, Bonnie, is her name in the English dub of the Pokémon anime. It comes from "Bonnie Brae", which is a variety of lemon. Between her, her brother, and her father, they're all named somehow relating to lemons, perhaps referencing their lemon-colored hair.
 * Her middle name, Sylvia, was randomly selected from a French name generator. French was chosen for this generator due to her home region, Kalos, being based on France.
 * Her last name, Kaji, was given to her after picking Clemont's last name. Kaji is the surname of Clemont's Japanese voice actor, Yuuki Kaji.

General

 * Her birthday, April 22nd, was randomly selected.
