Harper and Sarah/Anime/Character

Harper and Sarah enjoy playing with Pokémon as shown in Yo, Ho, Ho! Go, Popplio! where they were pulling on 's cheeks which resulted in them getting shocked and with in The Ol' Raise and Switch! where they were jumping on its back. They also enjoyed to tease her older sister, Lana, such as asking if was her boyfriend, and even after she denied it, continued to ask it. They teased her of having Ash as a boyfriend again in All They Want to Do is Dance Dance!.

The twins often tend to fight over certain things, such as a fan in The Dex Can't Help It! and a pillow in the Poké Problem segment of SM094.

A different side to Harper and Sarah was seen in A Haunted House for Everyone!, when Lana managed to scare them by forcefully yelling at them. This has enabled her to control their antics, as seen in the Poké Problem extra scene of the aforementioned episode.
