From Bulbapedia, the community-driven Pokémon encyclopedia.
Natalie (Japanese: ナオコ Naoko) is a character of the day who appeared in The Lotad Lowdown. She is the youngest sister of Rita and Nicole. She is voiced by Leah Applebaum in English and 西原久美子 Kumiko Nishihara in Japanese.
Natalie, along with her older sister, run a Flower shop near the lake of the Lotad. When Ash and co. were playing at the lake with the Lotad, Natalie told them to come with her to get lectured. But instead of them being lectured, she gets lectured by her older sister Nicole for being rude to the travelers. When Natalie saw how Brock treated her sisters with more kindness, she gets a bit jealous, showing that she had a crush on him.
Afterwards, wherever Brock is, Natalie is always next to him, willing to do whatever Brock wants or needs. Natalie's infatuation for Brock also leads her into trouble when she decided to search for a Sitrus by herself, thinking that it would help Brock achieve his goal as a Master Breeder. After finding a Sitrus Berry, Natalie suddenly gets attacked by a swarm of Beedrill. Brock comes to the rescue and saves Natalie from danger.
At the end of the episode, Natalie gives Brock a list of Berries and their effects on Pokémon, which she promised to do earlier in the episode.
