Wong debuted in Strange Tales #110 (July 1963), created by Stan Lee and Steve Ditko. He appeared in the 2006 Dr. Strange: the Oath miniseries.

Wong is the descendant and look-alike of Kan, a Chinese monk who lived roughly one thousand years ago and was a student of the occult. Kan was also a teacher and a healer, and though his order of monks was devoted to the ways of peace, he was also a skillful warrior who would fight when necessary.

One day, Kan discovered a strange temple. Exploring it, Kan was drawn against his will through a mystical black mirror into an other-dimensional realm. There Kan met Jehan, king of Siridar, his sister, Princess Shialmar, and their court magician, Vung, the one who had cast the spell drawing Kan through the mirror. Jehan persuaded Kan to lead his people in a war against the Wizard Kings who ruled this other-dimensional realm. Kan agreed to do so. During his time in this realm, Kan and Shialmar fell in love with each other.

Ultimately, Kan led his forces to complete victory over the forces of the Wizard Kings, and all but one of the Wizard Kings were killed. But Kan did not realize he was a pawn in Vung's secret plans. Vung captured both Kan and Shialmar and prepared to sacrifice them to the demonic race he secretly served, the N'Garai. Shialmar offered the N'Garai her own soul in exchange for power. The N'garai complied, transforming Shialmar into the Shadowqueen, a sorceress of great mystical power who was nearly incapable of love. The Shadowqueen slew Vung and sent Kan back to China.

Back on Earth, Kan returned to the life of a priest. Kan deeply regretted aiding Vung in defeating the Wizard Kings and sought to atone by devoting his life and those of his first-born male descendants to the service of mystics who themselves serve the forces of good. Ever since then, the firstborn males of Wong's family have carried on this tradition. For the ten generations preceding Wong's, the first-born males have served the Ancient One, the former sorcerer supreme of the Earth dimension. The last of the members of Wong's family to serve the Ancient One was Wong's own father, Hamir the Hermit, who remained with the Ancient One up to the time of the latter's death.

Wong was born in Kamar-Taj, the first-born son of Hamir, and thus his life was dedicated to the Ancient One from earliest childhood. When Wong was four years old, Hamir presented him to the Ancient One. Subsequently, Wong was sent to a remote monastery to become a student of the martial and mystic arts of Kamar-Taj, and receive training in how to serve a master sorcerer. Wong's relatives were allowed to visit him on occasions. Shortly before Wong's tenth birthday, Hamir brought a young couple to the monastery to visit Wong and made a marriage pact with them, betrothing Wong to their as yet unborn daughter. During his training at the monastery, Wong mastered certain Eastern martial arts. He remains highly adept in the martial arts, although since actually becoming a servant he no longer practices them as much as he once did.
