Hana Stoppable
Voiced by: Grey DeLisle
Hana Stoppable is Ron's adopted baby sister. Hana Stoppable's name is both a play on "unstoppable" (through her nickname, Han) and she is ethnically Japanese, evident since it was Sensei who helped arrange the adoption and the fact that her name is Japanese for "flower". Ron is resentful at first but then becomes her true big brother. He later discovers her mystical and martial arts skills in "Oh No, Yono". She may be related to Yori as seen in that episode. As the adopted member of the family, she is most likely raised Jewish.
