Fairy Godmother

The Fairy Godmother is Cinderella's godparent.

Kingdom Hearts
''A powerful but generous and good-hearted fairy who helps Sora and his friends. Slightly absent-minded, but an expert at magic. She gives Sora and the others lessons in magic as well as advice on their journey. She first appeared as Cinderella's fairy godmother in "Cinderella" (1950)''

Origin
In Disney's animated production of Cinderella, the Fairy Godmother appears to Cinderella to grant her a ride and beautiful clothes to go to the Prince's ball.

In the sequel Cinderella II: Dreams Come True, she helps the mice make a book for Cinderella, which is a very minor only showing up in the movie a couple of times.

In the threequel Cinderella III: A Twist In Time, her magic wand gets stolen by Anastasia, one of Cinderella's stepsisters.

Kingdom Hearts
In Kingdom Hearts, when her world, Castle of Dreams is destroyed, she moves to Traverse Town and lives with Merlin. She always appears in the form of a small carriage that's identical to the one she created for Cinderella. When you talk to her, she will return to her true form.

If you give Summon Gems to her in Kingdom Hearts, she will turn them into Summon characters. Among these are the Earthshine, Watergleam, Naturespark, and Fireglow. Respectively, these turn into Simba, Dumbo, Bambi, and Mushu. After these summon gems are turned into summon allies, she gives Donald the Lord Fortune.

Birth By Sleep
She may return in Kingdom Hearts: Birth by Sleep as her world is featured, but is still unknown at time.
