Bubbles 1997

Bubbles does have a tendency to be overemotional, despite having a habit to be ditzy, naive and sensitive, leading to her sometimes being regarded as the group's weakest link, by friends and foes alike. She can be quite prone to tears. However, she can become very independent and aggressive, let alone extremely mad when tempted, as seen in Bubblevicious. Out of all the Powerpuff Girls, she is the most feared by Mojo Jojo after having single-handedly taken him down in a fit of rage in the aforementioned episode. At one point, Bubbles gets severely hit on her head and dresses up as Mojo to fight her sisters.

After the girls were created in The Powerpuff Girls Movie, Professor Utonium named her Bubbles for her cute, bubbly, and joyful attitude (which she revealed by giggling when he named Blossom). Her best friend is Octi, a stuffed octopus given to her by the Professor. Her special ingredient is sugar and her signature color is light blue. She was also told in an interview from The Powerpuff Girls Movie that she was not afraid to show her emotions. She is also generally shown to be very caring of her sisters and the Professor as well as others.
