Isabelle likes doing the Leekspin in her hometown, Tokyo, Japan. She has a crush on Timonthy and a strong friendship with Shawna. She is the opposite of Misty, whom she dislikes. Isabelle is hyperactive and sometimes climbs up trees or houses. Her catchphrase is "I feel ready to Leekspin!" ("I'm all pumped for this" in the Japanese version). Despite this, she is not fond of spinning herself as seen in Isabelle's Long Spin. In The Spinning Bombs, it was revealed that Isabelle doesn't like bombs.
