Ice Witch

The Ice Witch is the main antagonist of the Studio 4°C OVA Tweeny Witches: The Adventures episode The Ice Witch and the Dragon of Fire and Ice.

History
The Ice Witch ruled the Blizzard Forest as the Dragon of Ice & Fire. She planned to take over the world as the strongest being. In her early days, she froze the land and her many foes (who were all sent by the previous grand master), the latter with her cursed blizzard.

As the strongest witches in the Magical Realm, Gana and her companions went on the mission, only to find Kunetke frozen the next morning even though they had made five magical barriers over their camp. When the remaining witches reached Blizzard Castle, the Ice Witch descended from the thundering sky. After freezing Tole as well, she stabbed Hanamomo with an icicle from her mouth.

Possessing the girl, the Ice Witch revealed to Gana that she kept Kunetke and Tole alive and that removing the icicle would kill her host. She took all Gana's companions hostage, eating Gana by coercion in an attempt to absorb the magic of the most powerful witch serving the grand master. The icicle eventually left Hanamomo, who woke up an unfrozen Tole. The Ice Witch, however, possessed Hanamomo again, grinning maliciously as she tried to stab Tole in the back. Gana managed to save both herself and her remaining companions as her spell immobilized the Ice Witch, who then fell and got stabbed by the top of Blizzard Castle.

Once a flash of lightning fell, however, the dragon disappeared. Returning in humanoid form somehow, the Ice Witch decided to seal Gana away as a last resort. Gana and her remaining companions were so tired in the previous battle that they could barely defend themselves from the Ice Witch's ice breath. And their mission had a bittersweet ending when Hanamomo burned the Ice Witch (whom Gana and Tole distracted beforehand at her suggestion) from the inside, slaying the evil dragon for good at the price of her own life.
