Bubbles Utonium is one of the main characters in The Powerpuff Girls.

The Ending Theme refers to her as "the joy and laughter," meaning that she is defined as very sweet in personality. In Meet Fuzzy Lumpkins short when she was hit from Fuzzy's meat gun, one of her pigtails turned into a chicken drumstick.

Bubbles do, however, 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. 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 Jojo to fight her sisters.
