Queen

The Queen (クイーン) is the ruler of the Garden of Light, and is also the one who grants the first generation's Pretty Cure. She is one of the two largest characters in Futari wa Pretty Cure, only rivaled by the Dark King himself. She has stated that she is impressed with the courage and hope of Pretty Cure, and aids them when she can.

Futari wa Pretty Cure
In Futari wa Pretty Cure the Queen rules over the garden of light and Nagisa and Honoka first meet her when they go to the garden of light to return the prism stones. Later she helps them temporally defeat the dark king before he is revived by the three seeds of darkness.

Futari wa Pretty Cure Max Heart
In the sequel, the Queen vanishes, separating into three parts: the twelve Heartiels, which represent her will, the Queen Chairect, which represent her heart, and Kujou Hikari, who represent her life. Although she and Hikari technically are the same person, they somehow managed to separate from each other at the end of the series, the Queen continuing to rule the Garden of Light, and Hikari staying in the Garden of Rainbows together with Nagisa and Honoka.

Etymology
The Queen got her name because she is the holy ruler of the light and the Garden of Light.

Trivia

 * The Queen is able to "teleport" herself to places, including the Dusk Zone, and minimize herself into the same size as a Pretty Cure.
