Blossom is "the smart one" and self-proclaimed leader of the Powerpuff Girls.
Her personality is "everything nice," her signature color is pink, and she has long red hair with a huge red bow and hair clip in the back.
She was named for having spoken freely and honestly to the Professor shortly after her creation.
She is often seen as the most mature, level-headed and composed member of the group, though she can be fussy, forgetful, overbearing, vain and overly analytical at times.
She tends to "parent" Bubbles and Buttercup, and often tries to play peacemaker between the two if they fight (though she is very quick to argue with Buttercup).
