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
 In Terra's storyline, she asks him to bring her Snow White's heart, and in exchange she would allow Terra to look in her Magic Mirror so he could find Master Xehanort. However, Terra couldn't do so and made the evil Queen angry, which causes her darkness to take control of her mirror to fight Terra. However, Terra wins and escapes. She also mentioned she doesn't care about hearts, claiming they fade easily.

In Ven's storyline, she appears in her witch form and prepares to carry the poisoned apple to Snow White, but drops it on her way. Ven, unaware of her motives, politely gives the apple back. She also tells to Ven how deep Terra is dabbling into darkness. The Seven Dwarves later inform Aqua that they chased the Queen off.

By the time of Aqua's arrival in the world, the Queen is nowhere to be found. The Magic Mirror states that his service to her has been completed. However she appears on a Awakening platform in Kingdom Hearts awake implying she did not die.

Appearance
The Queen is a pale-skinned woman with blue eyes, red lipstick, and seemingly penciled-on eyebrows. She wears a gold crown with five spikes on the front and a jewel on the tip of the middle and tallest spike. She also wears what seems to be a black balaclava that covers her ears, neck, and hair and only leaves her face exposed. She wears a close-fitting, han blue dress with enormous hanging sleeves with white cuffs. The Queen's dress has a high collar that is white on the inside and she wears a red cape, much like Snow White and The Prince. She also wears a gold pendant around her neck with a ruby set in it, as well as a long, rope belt tied around her waist.

In her witch form, the Queen dons a black, hooded robe that retains the hanging sleeves of her dress. Her physical appearance changes from that of a youthful queen to that of an ugly, old witch with long, tangled white hair. She has thick, black eyebrows, gold eyes, and dark rings around her eyes. Her nose becomes long and crooked and gains a large wart and she only has one visible tooth on her bottom jaw. Her hands are gnarled and have pointed, dirty fingernails. In this form, the Queen is also often seen with a basket filled with poison apples. She also seems to wear grey slippers.

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, and transformed herself 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, and sent the villain toppling off a cliff when one of her own schemes backfired.

Trivia

 * The Queen's first appearance in the Kingdom Hearts series was actually in the first Kingdom Hearts, a picture of her witch form appearing on Snow White's stain-glass podium in the Awakening.
 * The Queen is one of two Disney main antagonists featured in the Kingdom Hearts series who do not serve as bosses in their own world, the other being Lady Tremaine. A similar case could be applied to Gaston, the villain of Beauty and the Beast, the only difference being that he did not appear at all in the series.
