Xanadoth Xanadoth is a supervillain appearing in American comic books published by DC Comics. The character was created by writer Brian Michael Bendis and depicted by artists Kevin Maguire and John Timms, first appearing in Superman (vol. 5) #23 (July 2020). Although appearing in a Superman title, the character serves as a reoccurring adversary for Doctor Fate (Khalid Nassour).
During Khalid Nassour's psychotherapy with Superman following the outing of his secret identity to the public, Xanadoth is accidentally awakened by an agent of the Department of Extranormal Operations (DEO) and assaults the Tower of Fate to claim the Helmet of Fate's power and add to her already overwhelming power. Nabu first reveals her origins as a Lord of Chaos so extreme both the Lords representing order and chaos banded together to seal her away. With Nabu's guidance and the timely intervention of the Justice League Dark, Superman and Doctor Fate manage to banish Xanadoth. Later, she reappears with intents to hijack Black Adam's body for her own means. Confident, she sends visions to Nassour and Zatanna, the top "mystic warriors" on Earth of a possessed Adam before achieving her goal and pilfers the Helmet of Fate. Regrouping, the Justice League and Justice League Dark combine their efforts to combat Xanadoth. Doctor Fate regains his helm, the team frees Adam of his possession, and a combined attack from Doctor Fate, Zatanna, Madame Xanadu, Adam, and newcomer Naomi McDuffie (whose powers amplify magic) defeats Xanadoth. Xeen Arrow Xeen Arrow was a vigilante hailing from Dimension Zero, an alternate world inhabited by telepathic giants. A scientist by day, he had a secret identity as the vigilante Xeen Arrow, being a counterpart of Green Arrow, whom he met when he was accidentally transported to Prime Earth.
Xerø
Xiang-Fa Minister Xiang-Fa was the ruler of the trading city of Chao-Tzu in Chinese Empire during the 10th century. In order to ensure China's Westward expansion, Xiang-Fa created an army known as the Yellow Warriors and a wall around the city. The army under Xiang-Fa's command opposed renegade Green Lantern Yalan Gur, who was then weakened by the Guardians of the Universe to become vulnerable to wood, and therefore, even the peasants could hurt him with their wooden clubs.
