The Angry Princess is the ghost of Dana Newman and the sixth ghost to be featured in The Black Zodiac.
Dana Newman was incredibly beautiful in life (according to Cyrus, she had the natural looks of a goddess), but was unable to recognize her beauty. Her self-loathing and low self-esteem from which doctors tried to save her from was only fueled by a series of abusive boyfriends, and led to her having breast implants, nose jobs, and other unnecessary procedures.
One night, while Dana was alone in a clinic where she worked, she tried to perform surgery on herself due to an imaginary imperfection on her face, but the unorthodox procedure went horribly awry, and left her blinded in one eye. She then gave up on beauty, and committed suicide in her bathtub by slashing herself with a butcher's knife until she bled to death. When her body was discovered, she was described by her loved ones as being "beautiful in death as she was in life".
Following her death, Dana's spirit remained bound to earth and with a hatred of people. Soon was captured by Cyrus Kriticos to become the Angry Princess. The Angry Princess was then moved to the basement of Basileus's Machine with the other eleven ghosts.
Ben Moss encountered the Angry Princess in her containment cube while in the basement, remarking, "Nice t*ts" at her, which visibly angers her, and she tries to attack him unsuccessfully. A short while later, when the machine is unintentionally activated by Moss, the Angry Princess is the first ghost to be released. She advances menacingly on Moss for mocking her earlier, then watches as he is sliced in half between two sliding, glass doors.
The Angry Princess then leaves the basement, which the other ghosts have haunted, and goes up to the house's bathroom. There, she watches Kathy and looks at herself in the mirror with vanity, ignoring her and then goes to the bathtub where she almost attacks Kathy. But fortunately for Kathy, the latter leaves the bathroom before the Princess can kill her when Arthur arrives asking her for Bobby. Later, when Dennis and Maggie are lost in the basement, The Angry Princess attacks Maggie but she dodges her effectively thanks to Dennis.
Later, a Latin chant causes the Angry Princess, along with the other eleven ghosts, to go to the center of the machine and power it up. When the Princess and the other ghosts are freed from Cyrus's trance, they throw Cyrus into a rotating crest of rings. The house then explodes shortly after, destroying its walls, and freeing The Angry Princess and the other eleven ghosts. She is seen apart from the other ghosts, and she's the last one leaving the house, seeing the house before vanishing.
- Butcher Knife: In her ghost incarnation, the Angry Princess wields the butcher knife she used to kill herself with.
- In the original script, she was called The Suicide and has a more marked running mascara across her cheeks. The script also notes the fact she cut her wrists with the knife.
- According to the DVD subtitles, the whispers which signal The Angry Princess's approach are her whispering, "I'm sorry." Her voice can be heard in other scenes whispering words; in the bathtub scene she can be heard saying "What is she doing?" when Kathy approaches and splashes the water on her face.
- In the bathroom scene, "I'm sorry" is also written in blood on the floor. In the script, these words are on the walls.
- Usually, an area that The Angry Princess is currently present at is covered in blood (visible only through spectral viewers), most notably her containment cube and the bathroom. It's very possible that the bathroom is actually the real bathroom where she died and placed there by Cyrus but re-arranged, given the fact that it's the only place where she can go besides the basement when free, implying that she has a strong connection with it and the words written with blood as her final suicide note.
- The whispers associated with The Angry Princess usually resemble soft, feminine moans.
- The Latin inscription beneath The Angry Princess's symbol in The Arcanum, "sibi mortem consciscere," roughly translates as "she commits suicide" in English.
- She is the third female introduced in the Black Zodiac.
- Her ghost file is represented by a shaving razor.
- In the behind the scenes feature, the actress, Shawna Loyer, stated that she believed her makeup process took the longest due to all the scars that needed to be applied.
- The actress Shawna Loyer was often mistook for many porn actresses such as Aria Giovanni and Shawna Lenee. Her only role in a movie has been the Angry Princess as she's retired from the media and dedicates herself to be a mother.
