Princess Morbucks is one of the recurring villains from the Cartoon Network original series The Powerpuff Girls. She is a spoiled rich girl whose personality is based on that of Veruca Salt from Charlie and the Chocolate Factory. She wants to become a Powerpuff Girl, but because she is evil, she can never achieve this goal, and as a result, she is often attempting to destroy Blossom, Bubbles, and Buttercup.
In the series' Christmas special Twas the Fight Before Christmas, Princess declares that, since her father is rich and can buy her any material goods that she wants, she has written to Santa Claus about her desire to be a Powerpuff Girl. However, the Girls point out to her that she is most definitely naughty, and therefore she will only be receiving coal from Santa. Princess furiously refuses to believe that, but she soon finds that her servants also seem to think so. She then takes her private jet to the North Pole, where she sneaks into Santa's workshop. When she finds his documents, she is dismayed to find that she is the only child in the world on Santa's "naughty" list, so she switches the headlines of the "naughty" and "nice" lists, making it look like she is now the only nice kid in the world, and all the others are naughty.
When Blossom, Bubbles, and Buttercup find out that Santa has mistakenly given coal to all the nice children in Townsville, Princess shows up and attacks them, having received superpowers from Santa. She gloats over the fact that she has now received what she wanted and plans to go tell Santa that the Girls are coming to destroy his workshop for branding them naughty. When they finally reach Santa's workshop, Princess tries to convince him not to listen to the Girls, but Santa has a hard time believing he shouldn't, since he knows that the Powerpuff Girls are good people. Princess then insults Santa and threatens to have her father build a parking lot over the workshop. This results in Santa finally realizing that Princess deceived him, so he places her name on the Permanent Naughty Plaque and strips her of her superpowers when she tries to escape. At the end of the special, the Powerpuff Girls bring Princess to jail while delivering Santa's presents, wrapped up as a present to the cops.
