Qi'ra is a fictional female in the Star Wars film series who was portrayed on screen by Emilia Clarke. It was originally thought that the name would Kira but they've changed the name slightly to Qi'ra. Qi'ra is the lead female character in the Solo - A Star Wars Story. but is not the only female in the film.
Qi'ra follows the long line of lead females in the Star Wars series, Padme Amidala, Princess Leia, Rey and Jyn Erso. All the lead females are all white with dark brown hair. In real life, the actress who plays Captain Phasma has blonde hair but we don't see her without her mask yet. The male characters are a bit more diverse and in no particular order, we have Lando Calrissian, Cassian Andor, Luke Skywalker, Chirrut, Bodhi and Finn.
Emilia Clarke is a thirty year actress from the United Kingdom who was catapulted to fame after her role as daenerys targaryen in the Game of Thrones series. In G.o.T., she has a blonde wig but in this and other films, she uses her natural hair.
As Qi'ra and Rey are both brown haired white females, there is again speculation that Rey's mother could be Qi'ra. When exactly Solo is set in the time frame may exclude Rey from Qi'ra from being Rey's mother. When Rogue One came out, Jyn Erso was considered as a possible mother for Rey given they also share the same racial traits. Its not the first time that Qi'ra has been mentioned as a possible character in the Star Wars movies. Rey had been referenced as being Qi'ra once.
There is a shot in the trailer where she is disembarking from a space ship with a droid, L3-37. It was believed that L3-37 belonged to Qi'ra but L3-37 is actually owned by Lando Calrissian.
Life doesn't get much harder in the galaxy than on the shipbuilding world of Corellia. Corellia is the home world for both Qi'ra and Han Solo. Han and Qi'ra are lovers who aim to get off the planet and journey across the galaxy, exploring and making money.
When they get their attempt to get off the planet, at the very last moment, they are separated and Qi'ra is forced to stay on the planet. Han joins the Imperial Navy in the hope that he will be able to buy a ship and come back and rescue her.
Three years later, Han is reunited with Qi'ra onboard Dryden Vos' sail barge where Han is with Tobias Beckett trying to make a deal. Qi'ra is a lieutenant of Dryden Vos and has a tatoo on her forearm to show she's owned by the Crimson Dawn. The Crimson Dawn is a large criminal empire that spans the galaxy. Qi'ra reveals to Han that she had done things unspeakable in the name of Crimson Dawn and isn't the same as he knew her. The tattoo is inspired by what happens in the real world where people are tatooed to show as a sign that they belong or owned by a criminal gang.
Qi'ra is told to go with Han and Tobias to get the raw Coaxium ore, process it and then hand it over to Dryden Vos on the desert/water planet of Savareen. It is Qi'ra who introduces Han Solo to Lando Calrissian who would go on to become Han's friend. Han takes part in a game of Sarbacc but ultimately losses everything. Han was hoping to win the Millennium Falcon off Lando so that he'd have a ship to get to Kessel and back. Lando wins everything that Han has so Han and Tobias persuade Lando to help take part in the operation for a cut.
On Kessel, Qi'ra is disguised as a woman of nobility who has two slaves, Han Solo and Chewbacca to hand over to work in the mines. Its all a ruse so that Han can get at the Coaxium and steal it.
Once the Coaxium is stolen and Han has managed to navigate the Kessel Run, the group are reunited with Dryden Vos on Savareen. It is at this point that double crossing starts beginning.
Enfys Nest, the marauder who had been chasing Han Solo through the film reveals herself and tries to persuade Han to join the rebels but Han declines. Tobias leaves the group but turns up again when Han and Qi'ra tries to trick Dryden Vos. Dryden wants to kill Han and when Han gets his chance to kill Dryden, Qi'ra prevents Han. Qi'ra stopped Han because she wanted to kill him instead.
After Dryden is killed, Qi'ra tells Han to leave with him which he does reluctantly. Qi'ra has assumed the role that Dryden Vos did, as a senior member of the Crimson Dawn.
Qi'ra contacts the leader of the Crimson Dawn who happens to be Darth Maul, the red and black Sith Lord from first film chronologically, The Phantom Menace. Darth Maul tells Qi'ra to come and join him on Dathomir, a blood red planet that hasn't yet appeared in the films, only in the cartoon series and expanded universe.
When the next movie in the Han Solo series gets made, Qi'ra will return alongside Darth Maul. Tobias mentioned a hot shot gangster from Tatooine putting together a crew for a mission implying Jabba, the Hutt and therefore both Jabba and Darth Maul are expected to appear. There had been talk of a trilogy so whether Jabba will appear as well is open to debate and speculation.
