The Queen

The Queen, also known as Evil Queen, Wicked Queen, the Witch, or Queen Grimhilde, is a character in Kingdom Hearts Birth by Sleep. She appears in her homeworld of Dwarf Woodlands as the expected main antagonist, taking on both her Queen and Witch forms. She is the stepmother of Snow White.

Kingdom Hearts Birth By Sleep
Scans have shown the Queen confronting both Terra and Ven in Dwarf Woodlands.

One screen shows her in her normal form, explaining to Terra that she isn't interested in a person's heart. She also tells Terra that if he kills Snow White, she will use her Magic Mirror to show him the location of Master Xehanort. In another shot, she's shown in her Witch form, with Ven handing her the poisoned apple which she had dropped. She would later give it to Snow White.

Origin
The Queen made her debut in Disney's first ever animated film; Snow White and the Seven Dwarfs. Stepmother of Snow White, she longed to kill the girl out of jealousy of her beauty. Consulting her Magic Mirror, she hired a huntsman to do the job. The man let Snow White escape, however, much to the Queen's displeasure.

She eventually found the girl in a cottage owned by the Seven Dwarfs, transforming into an old hag; her intention was to look like a kindly grandmother, yet this was not the case. She convinced Snow White to bite from a poisoned apple, that would kill her unless she received Love's First Kiss. The Dwarfs went after the Queen, however, the villain sent toppling off a cliff when one of her own schemes backfired.
