Princess Kenny is the princess alter-ego of Kenny McCormick. She appeared throughout Season Seventeen's Black Friday trilogy, consisting of "Black Friday", "A Song of Ass and Fire", and "Titties and Dragons".
Originally, Kenny was a member of the Xbox One-supporting group, under the name Lady McCormick, but he betrayed them to become the leader of the PlayStation 4-supporting group, because Wizard Cartman would not let him be a princess.
In "Black Friday", Wizard Cartman sought out Lady McCormick to tell her to come to a meeting about getting cheap Xbox Ones. In the Garden of Betrayal, Cartman talks to Lady McCormick about the possibility that Sir Kyle could betray them, and tells her that her influence could be used to "take care" of Kyle, if it became necessary to do so. However, Kenny goes on to betray Cartman, and the Xbox One-supporters, by becoming the leader of the PlayStation 4-supporters, taking the title of "Princess Kenny".
In "A Song of Ass and Fire", Princess Kenny gives a narration about the coming war between the supporters of the Xbox One and the PlayStation 4 and asserts that her followers would fight until she was accepted as the princess of both sides. Eventually, Cartman brings his Xbox army to Princess Kenny's backyard, asking for their surrender and insulting Kenny for wanting to play the role of princess, which Kenny refuses, calling Cartman a "ball-lickng lesbian". Later, the Sony President comes before Princess Kenny with the Sony Princess Box. Opening the box, the Sony President gives Kenny a medallion, which turns Kenny into a Japanese princess.
In "Titties and Dragons", Princess Kenny receives orders at the Sony Headquarters and stops Microsoft's blockade of ships, filled with PlayStation 4s, en route to the South Park Mall. Later, Kenny is invited to a "wedding" at the Red Robin by Cartman, where she is told she will be accepted as the princess of both sides, after whitch, she jumps out the window and falls hard on the ground, with blood, to the sony workers dismay, but she gets back up and brushs herself off. While the "wedding" appears peaceful at first, Sir Kyle betrays Cartman, and the covert Xbox One-supporters, by joining the PlayStation 4-supporters. After Bill Gates kills the Sony President in the Red Robin, Princess Kenny, along with all the others, apathetically gets the Xbox One from EV Games.
Prior to being titled as Princess Kenny, Lady McCormick wore an unkempt blonde wig and a pink dress over Kenny's usual parka. The blonde wig is similar to the one Kenny wore in "Cartman Joins NAMBLA" when posing as a girl.
Princess Kenny has a styled golden-blond wig (the same color as Kenny's natural hair), topped with a golden crown. She wears a bejeweled white and purple dress with a gold trim, gold shoulder guards, and white gloves. Again, the entire princess outfit is worn over Kenny's usual parka; however, an unused earlier design gets rid of the parka and instead has Kenny wear makeup, with the dress being colored orange.
After becoming a "Japanese princess", Kenny takes on an "anime" look, complete with large, purple eyes. In her anime incarnation, Kenny speaks intelligible (and mangled) Japanese, although her voice is still slightly muffled and is an obvious female impersonation. She seems to refer to herself in the third person, a trait commonly associated with "cute" characters in anime. She also has the power to solicit extreme admiration from (other) males simply by acting cute, a trait carried over (somewhat) to her non-anime incarnation in The Stick of Truth. This version of Princess Kenny may be an exaggerated parody of the sector of the South Park fandom that often draws the characters in "kawaii" anime style and characterizes them as such.
Kenny's princess costume and wig are heavily based on the dress and hairstyle of various incarnations of Princess Zelda, a recurring main character from from the Legend of Zelda series.
Kenny appears in the game South Park: The Stick of Truth in his princess alter-ego as a companion to the player, and later reveals herself as the main antagonist of the game, betraying his friends and becoming the final boss of the game.
Kenny first appears as a member of the human army, being Cartman's right hand man and the princess of the Kingdom of Kupa Keep. Despite her high rank, she is still mocked by Cartman due to Kenny's choice of being "a chick" and uses her as a target to test Douchebag's new fart ability. Kenny later becomes a companion to the player and can accompany her through battles, having abilities like calling her rat friends for help (who can also kill her in the misuse of the power), exposing her "Double D's" to charm enemies and take their guard down, etc. She participates in many battles, including Craig's rescue mission at the school, the assault to the Inn of the Giggling Donkey and the battle against the elves at the school. Like many other characters, she is a member of the army that assaults Clyde's fortress.
However, after the government shows up and the chief agent takes the Stick and offers it to the kids to share power with him, Princess Kenny allies herself with the agent and takes the Stick for herself, betraying her friends, who refused the Stick for friendship. Morgan Freeman explains that inside the game's fiction, Kenny is the daughter of an orc and an elf, the original holders of the Stick of Truth, and that her entire orc community was slain by human and elves, and then she had sworn revenge on them, by getting the Stick of Truth and avenging her fallen people.
The player and his companions battle Kenny and after being defeated for the first time, Princess Kenny drinks a sample of the Nazi virus, and becomes a Nazi Zombie, greatly increasing her strenght and resistance. As all the companions are taken out of battle (or he avoids this and kills her enough), Douchebag is left with little chances of defeating Kenny, so Cartman decides to break the Gentlemen's Code by having Douchebag fart on Kenny's balls. As Cartman holds Kenny, Douchebag releases a fart on Kenny's groin, defeating her and causing a flash that expands through the town and cures the Nazi Virus.If you don't fart on Kenny's balls she'll break Cartman's hold and kills him, and you have to start the boss all over again.
Despite being defeated, Kenny can still be used as a companion after the credits end. It is implied he made up with the others and as said by Butters he was just "PMSing".
The following quotes are in Japanese and are from Princess Kenny's anime incarnation. She retains Kenny's usual muffled speech in her regular incarnation.
- "Princess Kenny reporto!" ("Princess Kenny is reporting!")
- "Hai, Princess Kenny assisto!" ("Yessir, Princess Kenny will help!")
- "Minna-san, Kenny kimasu!" ("Everyone, Kenny has arrived!")
- "Minna-san, ii yo. Princess Kenny ganbaru." ("Everyone, it's all right. Princess Kenny will try her best.")
