LukeLeia

Lukeleia is the familyship between Leia Organa and Luke Skywalker from the Star Wars fandom.

Canon
Luke and Leia are the twin children of Anakin Skywalker and Padmé Amidala. Like their father, the two are strong in the force.

The twins were separated at birth, due to the fall of the Galactic republic and the death of their mother. Luke was placed in the care of his Aunt and Uncle, and given the surname Skywalker. Leia was adopted by Bail and Breha Organa, and grew up on the planet Alderaan as a princess. The twins grew up unaware of their connection to the force, or that they had a secret sibling somewhere across the galaxy.

Luke first becomes aware of Leia when he finds R2-D2, who has a recorded message from Leia stored within him. Luke brings the message to Obi-Wan Kenobi, and they set out to rescue Leia from Darth Vader. Luke disguises himself as a Stormtrooper and finds Leia in one of the cells. She famously remarks that he's a "little short for a Stormtrooper". The pair escape the prison cell and run through the Death Star. At one point, before swinging across a deep pit, Leia gives Luke a kiss on the cheek "for luck".

Luke and Leia spend much of The Empire Strikes Back apart from each other, with Luke training on Dagobah with Yoda and Leia on the Millenium Falcon with Han. However they reunite on Bespin near the end of the film. Luke calls out for help, and Leia senses him through the Force. She directs Lando on where to fly the ship, and they rescue Luke. This is the first inkling we receive from the films that Luke and Leia might be connected as something deeper than friends.

Fanon
Lukeleia is the main familyship of the whole Star Wars fandom, as they are part of the Original Trilogy.

As Luke and Leia are not revealed to be siblings until the final installment of the Original Trilogy, many fans shipped the two characters romantically in the early days of the fandom. This was likely due to the implication that Luke had a crush on Leia in the first film, as well as the kiss they shared (to make Han Solo jealous) in the second film. However, the majority of fans nowadays only ship the two characters together as a familyship. They were finally revealed to be twins in the final film of the Star Wars prequel trilogy, and were only known to be siblings prior to that movie's release.
