Bonnie is the sister of Clemont in the anime and one of Ash's major traveling companions in Kalos.
She is a young, adorable and very pretty little girl with golden-blonde hair and blue eyes. She wears a brown sleeveless top with a soft black bow on it and she wears knee length black leggings covered by a white skirt resembling a cloud under it. Bonnie also wears pink Mary Jane shoes and a yellow purse.
She has a great love for Pokémon. She has strong ambitions and goals of being a Pokémon trainer, despite not being of age to be a trainer yet. She tends to forget she is the younger sibling and becomes very protective of her older brother Clemont. As a result, she'll often look for a beautiful girl to be her brother's wife, much to his chagrin. She is sometimes annoyed with his over-protectiveness and nagging, but she understands that he loves her very much, and she returns these affections. When frightened or stressed, Bonnie will reach for her brother's hand, or hide behind him, thus displaying a keen element of trust in their relationship.
Bonnie is Clemont's little sister. She travels with him and supports him in his battles. She is younger than the age of 10.
Taking care of
Clemont caught a Dedenne upon Bonnie's request to take care of since she is too young to be a Trainer.
Bonnie befriended a Flabébé and wanted Clemont to catch her. But she finds out that she belongs to someone else. She later helps her find a new flower for her so she can restore her health and return to her owner
Bonnie is a reference to Max, as she is a younger sibling. Like Max, Bonnie shares the following:
She does her best to help out her older sibling, like Max does with May.
She is related to a Gym Leader, that being Clemont, like Max is to Norman, the Gym Leader of the Petalburg City.
She is also a little similar to Brock, as she'll often propose to a beautiful girl to be her brother's wife, but ends up being pulled away. However, Brock will almost always flirt with an older girl, usually a Nurse Joy or an Officer Jenny, while Bonnie will go after any beautiful girl, either a little younger than, as old as, or older than Clemont, (yet only the latter one has happened so far) and so far, none of them were Joy or Jenny.
She is Ash's first female companion that is not an actual Pokémon Trainer.
She is also Ash's first female companion to be younger than the age of 10.
Unlike Max, she is the first younger sibling traveling with Ash that is based off a game counterpart. Also, she has a Pokémon, despite not being of age to have one yet.
