Warlock of YS
Searching for her missing father on Earth, the heroine Zatanna had faced the Druid alongside the size-changing Ray Palmer. Zatanna had read ancient manuscripts and learned of the land of Ys. She tried to conjure the blue flame but was able to stop it from bringing her to the Other Side of the World when she learned how truly powerful it was. Her magic kept her held between Earth and Ys. Forced to find another avenue to Earth, the Warlock sought out the power ring of Green Lantern Hal Jordan. Zatanna was aware of this but could not prevent the Warlock from using her as a stepping stone to send a sorcerous entity, Patch-Eye Pete the Pirate, to draw Green Lantern into his clutches. Zatanna dueled with the Warlock's magic and granted Green Lantern her powers.
