Alien Princess

aka: Alien Prince

Seven years before she became Starfire, she was Princess Koriand'r.

She comes to you from a world far away. When they say she's out of this world, it's not hyperbole. And she's royalty. Ladies and gentlemen, may we present, Her Royal Highness, The Alien Princess.

She may be a Green-Skinned Space Babe, a Rubber-Forehead Alien, or she may look like one of us. At least, externally.

Whatever the case, she hails from another world, and will undoubtedly have customs and traditions vastly different from a human protagonist. Because Most Writers Are Male, this may include coming from a society with No Nudity Taboo, making her an Innocent Fanservice Girl. Though in some settings, she may also be The Vamp, perfectly aware of the effect she has on the hero of our story. If her race has sufficiently advanced tech, she may have much in common with the Mad Scientist's Beautiful Daughter. She may or may not ask What Is This Thing You Call "Love"?.

Sometimes, she's a Princess Classic. Sometimes, she's a Rebellious Princess. She may come to be on our world to escape an Arranged Marriage. Or maybe, someone ends up engaged to her due to misunderstandings.

Often she will arrive either commanding or fleeing a vast interstellar armada. In some settings, however, she may be the Last of Her Kind.

She may or may not be part of a Planetary Romance, and/or a Space Opera.

If the story is set on Earth, our Princess may well be the herald of an invasion fleet, wittingly or otherwise. If she gets engaged to a human, her Father might try to annul the engagement with an Earth-Shattering Kaboom, making her an Unwitting Instigator of Doom. She could also, as the next in line for the throne, cause a host of jealous suitors and interstellar foes, who either want her as a prize or a hostage, to descend on the Earth.

If the story is set on another world, expect our Earthling Audience Surrogate character to influence the Alien Princess during a Rescue Romance. She will likely be impressed by the Earthling's feats of bravery and daring, and her culture and customs may demand he marry her, even if he's not aware of it. He will earn the ire of any previous suitors, even her unwanted ones. On her native world, she may overlap with The Chief's Daughter.

Merely being a straight-up human princess in a sci-fi setting does not qualify her for this trope; for that, see Feudal Future. (Sorry Princess Leia, it's not that we don't love you.)

Her Spear Counterpart is the Alien Prince, less common, though not unheard of. He's often the Conquering Alien Prince.

Examples:

Advertising

• Quisp and Quake: Quisp is the Crown Prince of Planet Q (he rejects the "king" title because he thinks it's too pushy) and has large eyes, the ability to fly, and a "scrooch" gun.

Anime & Manga

• Di Gi Charat: Dejika is the princess of the eponymous planet, Di Gi Charat, with cat ears, eye beams, and who came to Earth to be an idol singer.
• Future Robot Daltanious: Very early into the series, the main protagonist, Kento, learns that he's descended from the Helios Empire — a.k.a., the very Empire Dr. Earl is from - and is next in line for the throne. Kento rejects all claims to royalty, wanting to live a normal human life, and gets irritated when Earl calls him "Kento-sama". Kloppen, Dolmen, Catine and most of the Heliosian nobility are villainous examples.
• Meteor Prince: Io is a prince from the planet Yuptia, who arrives on Earth in order to mate with the protagonist Hako, who he believes shares the same heart wavelength as him. While she is initially put off by his advances, she slowly falls in love with him.
• Outlanders has Kahm, a Horned Humanoid Alien Princess of the Santovasku Empire. She enters the series running from an Arranged Marriage.
• Project A-Ko: C-ko Kotobuki (Shiiko), though ignorant of the fact at first, is the lost princess of the Lepton Kingdom of Alpha Cygni, a seemingly One-Gender Race of women warriors (though it can be hard to tell with some of them at first). C-ko eventually turns down all efforts to be returned to her home kingdom, electing instead to remain on Earth with her close friend, A-ko.
• Raideen:
  • Reiko Hibiki is actually Princess Lemuria of the Mu Empire. Her son is the show's protagonist, making him a Half-Human Hybrid. He was raised by his father as Lemuria had to find the La Mu Star device to stop Barao from taking over the world. By the end of the anime, Akira's all that's left of the Mu Royal Family as Lemuria gives her life to defeat Barao. Tragically, she could never have the mother-son relationship with him that she dreamed of.
  • Charkin is the Prince of the Demon Empire and ends up committing Seppuku halfway through the anime.
• Robot Romance Trilogy:
  • Voltes V has Prince Heinel, the Prince of the Boazanians. He seeks to conquer Earth to bring honour to his family name, as his father opposed the cruelty of the Boazanian Fantastic Caste System and led many slave rebellions against Emperor Zambajil, thus earning the moniker of "the Traitor" amongst his fellow nobles. Based on real-life French Aristocrats, Heinel dresses in exquisite blue furs and wields a longsword, which he uses to force others into submission. He is also skilled at using daggers, commanding militia, riding horses and piloting mecha.
  • Daimos has Richter, the Prince of Planet Baam, who seeks to invade Earth as revenge for the loss of his father, who the Earthlings assassinated during a peace conference. It's later revealed that it was all a great big lie and he was tricked. In actuality, his father was poisoned by his personal advisor, Olban, and he used the despair of the Baam Empire to crown himself as the Emperor. His sister, Erika, is the Love Interest of the main character.
  • In Victory Five, it's revealed that Heinel has a twin sister named Marine. Like Heinel before his Heel–Face Turn, she is a cruel aristocrat that wants the Boazanian Empire to dominate the world. She despises Heinel because of an ancient Boazanian custom stating that twins are bad luck - which was why when she was born, she was given to a noble family of another planet. Unlike her brother, she has no redeeming qualities.
• Space Battleship Yamato 2199: Sasha and Yurisha are Princesses of the planet Iscandar. Both venture to Earth in an effort to provide relief from the war with Gamillus. Yurisha was rendered comatose for a time by a terrorist attack, and became the navigation system of the eponymous Yamato during that period, until she was revived towards the end of their journey. Sasha died in a crash landing on Mars, delivering the Wave Motion Core. Yurisha also helps to persuade her sister, Queen Starsha, to allow the humans to have the Cosmo Reverse System.
• Tenchi Muyo!: Ayeka and Sasami are both Human Aliens from Jurai, with a host of strange powers and outlandish hair colors. Ayeka is more concerned with her royal status than Sasami is. The Juraian Emperor enters the story at one point, trying to get his daughters to return home, and setting up an Arranged Marriage to a Juraian noble named Seiryo, stating that Tenchi must defeat Seiryo in a duel if the girls wish to remain on Earth.
• To Love Ru:
  • Lala is a Princess on the run, initially, until a teleporter accident puts her in Rito Yuuki's bathtub, leading to the two becoming Accidentally Engaged.

  • Run Elise Jewelria, Princess of Memorze, as well as her Gender Bender counterpart, Ren Elise Jewelria. The two become separate individuals in To Love Ru: Darknesss.
• UFO Princess Valkyrie: The titular Valkyrie, as well as her sister, Hydra, are Princesses of the planet Valhalla. Valkyrie crashes on Earth trying to escape an Arranged Marriage. And Hydra crashes on Earth trying to drag Valkyrie back to the Arranged Marriage so that she won't have to marry the guy herself.
• UFO Robo Grendizer: Duke is the Crown Prince of Planet Fleed, possesses super-agility and pilots the Grendizer against the Vegans who murdered his family. He also falls in love with a human girl, despite being engaged to the daughter of the Vegan leader.
• Urusei Yatsura: Lum set many of the standards for Alien Princesses in manga and anime. Though humanoid, Lum has bioelectricity and can fly. She also got accidentally engaged to Ataru Moroboshi when he grabbed her horns in a game of tag to save the Earth, and now she lives in his closet. Her relatives and other aliens frequently show up, including the Queen of Neptune Oyuki and Benten of the Gods of Luck clan.
• Voltron: Princess Allura fits this trope to a tee. That said, she still looks human enough (even in Legendary Defender).

She crashes to Earth, is decidedly of the Green-Skinned Space Babe variety, briefly forms a sexual relationship with him before cheating on him and insulting his sexual prowess, and he discovers later that the alien STD she gave him causes his body to melt.
