Hana Stoppable is Ron's ethnically Japanese adopted baby sister. Her name is Japanese for "flower". She apparently is from the Yamanouchi Clan as it was Sensei who brokered the adoption, and later Yori claimed Hana was "like a sister". At first Ron is resentful of her and how his parents sprung her on him as a surprise, referring to her as "the intruder", before he discovers she is a prophesied weapon called The Han. Eventually Ron warms up to her, fully accepting his role as her big brother. Her mystical and martial arts skills grow until she finally defeats Yono the Destroyer in "Oh No, Yono". As an adopted member of the family, she is most likely raised Jewish. She is voiced by Grey DeLisle.
