Bubbles is the sweet and cute one of The Powerpuff Girls. She acts like the little sister of the team. She has a high-pitch voice and is very girly and innocent. You can use the original Powerpuff Girls version voiced by Tara Strong as a reference, you can reference The Powerpuff Girls Z English dubbed version of her if you would like, or can combine the two voice to make up your own version. Remember to stay true to the character.
