Cinderella is one of the classic Disney characters who appears in Kingdom Hearts. The main character from Walt Disney's 1950 film Cinderella, she plays a small but important role in the game as one of the Princesses of Heart. Maleficent destroyed her world and took her into captivity as well.
 Kingdom Hearts Birth by Sleep
Cinderella was born a wealthy girl, but after her mother passed away while she was still young, her father re-married another woman, Lady Tremaine, to care for Cinderella. However, after her father passed away too, her evil stepmother revealed her true self and turned her into her own home's maid.
One day, the King of the Castle of Dreams holds a ball for Prince Charming invites all unmarried women from the kingdom to help him find a bride. Instead of letting her join them, Lady Tremaine and her daughters give her unfinished chores to prevent her from getting ready for the ball. During Ventus' visit, he assists her mouse friend, Jaq, in making a dress for her while Cinderella finishes her chores. Despite his appearance, Cinderella believes him to be a mouse due to his unexpected miniature size.
Cinderella's stepsisters angrily tear apart her dress. Cinderella runs to the garden in tears just as Terra arrives, who encourages her to continue to believe in her dreams for a better future. Eventually, her Fairy Godmother helps her make a beautiful princess gown and a carriage to take her to the ball, with Terra as her bodyguard. While at the ball, she meets the Prince and they fall instantly in love with each other. While dancing, she and the prince are suddenly interrupted by a gigantic Unversed until Terra comes to their rescue. But not soon after the Unversed is defeated the clock strikes midnight and she is forced to leave the ball before the Fairy Godmother's magic runs out. As she runs through the Grand Hall, she loses a slipper.
Prince Charming declares to find the girl of his dreams with the glass slipper by letting every girl in the kingdom try it on. Lady Tremaine, having discovered that Cinderella is the girl at the ball, locks her in her room and attempts to make one of her daughters the Prince's bride. However, Aqua and Jaq cooperate and manage to free Cinderella just before the Grand Duke is able to leave. Lady Tremaine trips him and the slipper breaks to pieces before she is able to try it on, but Cinderella pulls out the second glass slipper from her pocket and uses it to replace the broken one.
The Grand Duke is about to take her to the castle when Lady Tremaine summons a gigantic Unversed to murder the princess, since she is now free. Aqua manages to destroy it and bring her safely to Prince Charming. Charming is at first surprised to see that Cinderella is in fact a servant girl as opposed to the princess he believed her to be, but nevertheless accepts her for who she is.
Some time after Xehanort's defeat, she is dancing around the ballroom with the prince while Jaq and the Fairy Godmother look on.
 Kingdom Hearts
Eventually, her world was consumed by the Heartless and she was taken and held deep within Hollow Bastion until all seven Princesses were collected; when her world was destroyed, the Fairy Godmother escaped, but, it is unknown what happened to Jaq and the other mice. It is unknown when she was captured but from scenes it can be assumed it was before Snow White and Alice placing her as either second captured or third either before or after Belle.
Once her heart was restored, she stays behind in the castle of Hollow Bastion with the other five princesses to hold back the darkness lurking out of the Final Keyhole, until Sora returns and closes it. Though the Final Keyhole is sealed, Cinderella and the others feel another dark power approaching from somewhere else (End of the World where Kingdom Hearts is held), and asks Sora to stop Ansem, Seeker of Darkness from fulfilling his evil plans while they remain behind to protect Hollow Bastion.
When Kingdom Hearts is sealed she is returned to her own world.
 Kingdom Hearts II
Cinderella has fair skin, long, blonde hair, and blue eyes. When dressed in her maid outfit, she wears a brown dress, a long-sleeved, pale blue undershirt, black shoes, and a white apron. She also ties her hair into a ponytail.
When in her ball attire, Cinderella wears long, white gloves that reach to halfway up her upper arms, as well as an elegant, flowing, white dress. The straps of this dress sport puffy disks decorating them. She also wears a white headband, white earrings, and a black choker. Though usually hidden by her dress, Cinderella wears her famous glass slippers in this outfit as well. She also ties her hair into a bun. In the original Kingdom Hearts, Cinderella wears this outfit, albeit her hair and dress are brighter in color. In her Awakening emblem, Cinderella's hair is brown and her dress has a slight blue tint.
Despite Kingdom Hearts Birth by Sleep being set ten years before the original Kingdom Hearts, Cinderella appears unchanged.
Cinderella has been known to be a very hardworking and honest young woman, who is skillful in doing multiple house chores each day and cooking as she constantly serves her stepmother and two stepsisters. She is not afraid to speak her mind and her dreams to her mouse friends, yet is completely passive and obedient to her step-family right until she goes to the ball. She has shown kindness to everyone around her, including her mouse friends and even to her harsh stepmother and mean stepsisters. She is shown to have unwavering patience and perseverance that has helped her, even when her first dress was destroyed by her stepmother and stepsisters and she seemed to have lost all hope. It was her strong belief in her dreams that allowed the Fairy Godmother to come and help her get to the ball.
 Powers as a Princess of Heart
Because Cinderella is a Princess of Heart, her heart holds part of the ability to open the Final Keyhole that leads to Kingdom Hearts, which can only be opened when she is joined with the other six princesses. Should her heart be lost, her body will remain in a dormant state until it returns.
In Kingdom Hearts Birth by Sleep, Cinderella becomes a D-Link for Terra, Ventus and Aqua separately after the events of her world, able to send them her power to assist them in battle. Terra and Cinderella have a Finish move called “Dream Waltz”. Aside from Cinderella, her fellow princess, Snow White becomes one as well for Aqua and Ventus.
While in link with Cinderella, the characters can lift enemies up into the air with magic and temporarily immobilize them. They can also make a powerful vortex to blow away their enemies.
Cinderella is originally from the Disney movie titled Cinderella. She was born wealthy, but after her father passed away, her evil stepmother, Lady Tremaine, turned her into her own home's maid.
When the King of the Castle of Dreams held a ball for Prince Charming, she wished to go but her stepmother and stepsisters forbade it. Instead of just forbidding her to go, they told her if she finishes all her chores and finds a dress to wear that she could go, but kept adding more chores to keep her from being able to. Her mouse friends encouraged her by secretly stealing different accessories to make a dress for her while Cinderella finished her chores. On the night of the ball, however, Lady Tremaine caught on quickly as Cinderella's stepsisters tore apart her dress. As Cinderella cried in the garden, her Fairy Godmother and her mice friends helped her make a beautiful princess gown and a carriage to take her to the ball, where she would find a new future.
