Rey is a fictional female in the Star Wars series. The character was portrayed on screen by Daisy Ridley. Her allegiance / loyalty is to The Alliance. Rey is the lead female in the Star Wars - The Force Awakens, a scavenger who lives on the desert world of Jakku. To survive, Rey scavenges a Star Destroyer that crashed during a battle between the Galactic Empire and the Rebel Alliance many years ago. What she scavenges, she hands to Unkar Plutt who gives her credits and food to survive.
Rey's home is a destroyed AT-AT Walker which although isn't much, it is none the less home for her. She rescues BB8, a small droid that will go on to affect her life. BB8 refuses to leave her sight and when Rey is given the option of selling it to Unkar Plutt, she declines to sell it, instead keeps it which lands her in trouble when people want the droid, both scavengers and the First Order when they arrive.
Not much of her history prior to finding BB8 has so far been revealed. Through a flash back scene in her first film, we see Rey being left on the planet by her parents but the identity of the parents have not been revealed yet
Through the droid, Rey meets Finn, a Stormtrooper deserter who tells Rey that he is part of the Rebel Alliance which is a lie but one that Rey gets taken in by. It is evident from early on that Finn has feelings and is probably in love with Rey, during Jakku, he is trying to grab her hand, trying to protect her he says. Finn was indoctrinated as a Stormtrooper from the moment he was captured as youngster so won't have probably experienced feelings or love for anyone. Finn and Rey steal the Millennium Falcon from a junkyard when Rey's craft is blown up. They attempt to get off the planet, however as soon as they get off the planet, the Falcon is captured by Han Solo and his co-pilot Chewbacca who announce that they're home. Rey reveals to Han Solo that they are trying to get the BB8 droid to the Rebellion so that they can help in the war effort. Han takes them to Takodana and to meet a fellow smuggler, Maz Kanata who Han believes is able to put them in contact with the Rebel Alliance, now called the Resistance.
It is on Takodana that Rey finds Luke Skywalker's lightsaber and when she picks it up, she gets visions of the past and future including of what is believed to be Luke Skywalker and R2-D2. The vision of Luke and R2-D2 is actually of the past, when Ben Solo rebelled against Luke's teachings and went on to become Kylo Ren.
In the same set of visions as per above, Rey sees Kylo Ren face off with someone on a snow world but doesn't see who it is. The images are a bit much for the youngling but Finn takes possession of the lightsaber and uses it to fight against a stormtrooper. During the First Order assault on Takodana, Rey is knocked out and is captured by Kylo Ren who whisks her back to his command ship.
On Starkiller Base, Rey is no shrinking damsel in distress, she begins to feel the Force Awaken inside her and uses the force to force a stormtrooper to free her from captivity. It is said that the soldier she persuaded was played by Daniel Craig, more famously known for playing British Secret Agent James Bond, only a rumour though. Rey manages to group up with Finn and Han Solo who have came to knock out the planets shield generators.
The Rebellion manage to knock out the shield generator by capturing Captain Phasma and forcing her to turn off the shields. The three rebels escape the base as its blowing up but once outside in the forest, they are confronted by Kylo Ren. Finn starts to fight Kylo but is knocked unconscious and it falls to Rey to take up the lightsaber and fight Kylo. The fight ends with Kylo defeated but its unclear as to whether he's been killed but Kylo almost dead-cert to make it to the next movie. For someone who had little experience of fighting with a lightsaber, Rey is a natural. Rey and Finn leave the snow planet in the Millennium Falcon piloted by Chewbacca as Han Solo was killed by Kylo when Han confronted his son inside the base.
When the Millennium Falcon reaches D'Qar, the rebel headquarters, the final piece of the puzzle as to where Luke is is put in place. Rey meets General Leia as shes called now and gives Leia, Luke Skywalkers lightsaber.
Rey and Chewbacca set off to the unknown planet where they find Luke Skywalker alone on a Rock Island in the middle of a large ocean. There's nothing said between the two characters and it ends there. In the follow up film, Luke receives his lightsaber and then tosses it casually away like it means nothing to him.
If you're expecting Rey to do anything like what Princess Leia had to do, i.e. wear a metal bikini whilst tied to a slug then you're going to be sorely disappointed. Talking of costumes, she remains in the same costume throughout the film, in much the same way as Princess Leia did in the Star Wars IV - A New Hope.
Its evident from the early scenes that Finn has an attraction towards Rey although it is reciprocated. From the moment Finn first sees that Rey is in trouble, Finn runs into action to protect her but he is involvement is not welcome. Finn continues to stick with Rey throughout the film.
At the end when Han Solo and Chewbacca are to sneak onto the Starkiller base planet, Finn volunteers to join them saying he worked on the planet which he did but only in sanitation. Finn just wanted to be in Han's team so he could rescue Rey.
Finn is knocked unconscious in the fight between Kylo Ren and Rey and Finn. Finn is taken back to the Resistance Headquarters and is nursed back to health in a medical pod. When Finn wakes up, the first thing he asks about is Rey and nothing else.
At the end of the second film, when Rey and Finn are reunited at the end of the movie, they embrace as friends. Romance is still on the cards between the two of them but nothing has happened and also Rey has competition in the guise of Rose Tico although Finn is recipricol to Rose.
When Rey travels to Ahch-To to meet Luke Skywalker, Luke is not interested in training Rey. Luke wants the Jedis to die out, Luke believes that the Jedis have had their time. Where were the Jedis when Sentator Palpatine from Naboo was working his way up to become the Emperor of the galaxy. Luke believes the Jedis should have sensed it and seen to stopping him.
Eventually, Rey with the help of Chewbacca who Luke is pleased to see on the island, Luke agrees to train Rey in the ways of the force. Luke doesn't like it when Rey starts to veer into the dark side of the force. When Luke asks to reach out, Rey thinks physically and reaches out with her hands which get slapped by Luke because its the wrong reach out. When the emotions turn to darkness and a hole, Luke decides to bring to a close the training.
Rey visits the dark hole she saw in her vision when she was reaching out with the Force. The hole leads to an underground pond and where she believes she will get to see who her parents are. When Rey looks into a mirrored wall, expecting to see her parents, all she sees is herself.
Kylo had a small interest in Rey in the first film, more for the lightsaber than for Rey herself. In the second film, Kylo is able to create a telepathic link to Rey where they talk at various points during the film including when Kylo is topless. Although Rey can see where Kylo is, the reverse is not possible, Kylo is not able to see Reys surroundings and so couldn't see where Luke Skywalker was. The link occurs a number of times throughout the film. It is similar to the link that Luke had had with his father Darth Vader in a couple of scenes in the original trilogy.
When the training ends, Rey goes to Supreme Leader Snoke's supermassive star destroyer and meets with both Kylo and the Supreme Leader. Rey hopes she can turn Kylo back into Ben Solo and work for the Resistance/Rebel Alliance. Rey is disappointed that she fails to turn Kylo. When Rey refuses to join the First Order even through being tortured by the force. After failing to get Rey to join, Snoke orders Kylo to execute Rey. Kylo turns on Snoke and kills him using Rey's lightsaber by turning it on and slicing Snoke into two pieces. Rey and Kylo work together to kill Snoke's Red guards.
Kylo tells Rey that her parents are nobodies, no one special. Kylo uses the fact that Rey doesn't know who her parents are to try and turn her to the dark side. Its not yet revealed exactly whether that is the truth or whether it was just something Kylo said to turn Rey. We'll have to wait to find out whether anything is revealed in the final film.
Rey escapes from Kylo adamant that she will not join the First Order. Kylo Ren has now assumed control of the First Order by Force strangling General Hux into submission.
After escaping from Kylo Ren, Rey helps the resistance escape from Crait by firing the Millennium Falcon guns whilst Chewbacca piloted the craft with help from his new friends, the Porgs.
There's not much we know of Rey's past except that she was deserted at a young age on Jakku and has had to fend and feed her self since that time. There is still speculation that she is the daughter of Luke Skywalker given that she has awoken the force within side her. She has the ability to control the minds of the weak and is able to move things with her mind. It is the awakening that Supreme Leader Snoke talks about when he talks about the 'There's been an awakening, can you feel it.'
Rey will be back for Episode IX when it comes out in 2019. Luke Skywalker won't be back in human form but maybe in ghost form to provide Rey with some new training. The romance between Rey and Finn will obviously be expanded on unless there is a new character who intervenes or tries to do what Lando Calrissian tried in Bespin before getting the cold shoulder.
Another theory to Rey's past is that Rey is the daughter of Jyn Erso, the lead female rebel alliance spy who breaks into the Death Star to steal the plans that the Rebel Alliance use to blow up the space station. This is based on the fact that Jyn Erso and Rey are both white females and that in the timeline, things could fit in, Jyn could quite easily fit the mother timeline. As Jyn Erso never made it off Scarif after stealing the Death Star plans, this rumour is 99% unlikely. Until the truth is revealed, you can't discount anything considering what plots have been done in the interests of entertainment.
Alternatively, she could be the daughter of Palpatine who was created in the Sith Lords dying days. As you need a mother to create a child, the mother, Palpatines mistress could have hidden her away so that Palpatine could never find her. There are rumours even that she could be the Force generated daughter of Darth Plagueis who is not dead after all. Darth Plagueis had a reputation for being able to create or destroy life.
Rey might be a clone of someone which she doesn't know. The memories that Rey has in her are possibly to make her think that she is not a clone. The only memories that we've seen of her is as a little girl being left on the planet. A traumatic event in Reys life could be blocking the memories of her parents, of what they looked like. A child her age would presumably have some memories of her life before that date. That she has no memories of before makes me think she might be a Force clone.
When Hasbro released an updated Star Wars Monopoly set, there were no pieces based on the female character. The pieces that were included were characters such as Luke Skywalker, Finn and Kylo Ren but no female characters. Hasbro were caught out by this and eventually created a Rey character.
