Wong was the descendant and look-alike of Kan, a Tibetan monk who lived roughly one thousand years ago and was a student of the occult. For the ten generations preceding Wong's, the first-born males in his line 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 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 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 asian 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.
Serving Doctor Strange
When Wong reached adulthood, the Ancient One sent him to the United States to his disciple, Doctor Stephen Strange. Wong was the first member of his family to come to America. Wong served Strange loyally and well for many years. During that time Strange succeeded the Ancient One as sorcerer supreme of the Earth dimension.
At some point after moving to America, Wong received word that the couple of his father's choosing had at last birthed a daughter.
At one point Wong was abducted by other dimensional sorcerers to the realm that was still ruled by the Shadowqueen. Doctor Strange followed Wong there and rescued him from the Shadowqueen's dungeon. Wong helped Strange battle the Shadowqueen, who finally perished.
Strange's secretary, Sara Wolfe, became strongly attracted to Wong, who began to reciprocate her feelings. However, Wong put an end to what might have become a romance with Wolfe, saying that it must not be because some of them had duties in their lives, and initially refused to discuss his decision with Sara. However, after Strange insisted that he explain why he had distanced himself, Wong finally admitted that he had grown fond of her but was not going to allow it to go any further because he was promised to another. Although Sara tried to go back to being friends, she remained upset for some days until Wong, realizing that he had caused her further pain by not fully explaining himself, finally told her about how his marriage had been arranged. Even though she now understood the situation, Sara considered it crazy.
Soon afterwards, Wong and the empath, Topaz, were both abducted to another planet by the alien sorcerer, Urthona, when the latter used his magical powers to steal Doctor Strange's house and the mystical talismans and books it contained. Urthona even viciously mutilated Wong's face while holding him prisoner, Strange defeated Urthona and rescued Wong and Topaz. Once Strange had transported them and the house back to Earth, Topaz used her healing powers to restore Wong's face to normalcy.
In order to rescue Wong and Topaz, Strange had found it necessary to unleash mystical forces that, he believed, destroyed the mystical talismans and books that Urthona had stolen, thus preventing Urthona from using them for evil purposes. (In actuality, and unknown to Strange, most of the the books and talismans were not destroyed but were instead spirited away by the mystical entity, Agamotto.) The disappearance of these talismans from the Earth dimension broke certain ancient spells holding various mystical menaces in check.
After discovering how bad the situation he had created truly was, Strange subsequently cast a spell causing the population of the world, including Wong and Sara Wolfe, to believe him dead. As a result, Wong and Wolfe perceived Strange as a man named Stephen Sanders. Strange made Wong and Wolfe the joint administrators of the Stephen Strange Memorial Metaphysical Institute, an institution for research into the occult. Strange then embarked on a long quest during which he succeeded in defeating a number of the menaces that the disappearance of the talismans had unleashed, most notably Shuma-Gorath.
During the months that Strange was away fighting to save Earth, Imei Chang arrived in New York City to be with her betrothed and apparently began living at the Stephen Strange Memorial Metaphysical Institute. Following the defeat of Shuma-Gorath, Strange returned to New York City and arrived at the institute where Wong introduced "Doctor Sanders" to Imei. Minutes later, Strange partially dissolved the spell, enough to release Wong and Sara Wolfe from his spell and restore their memories of what had actually happened. Realizing that Strange was not dead, Wong and Wolfe warmly welcomed him back.
When Imei was apparently altered into a hideous demon by one of Strange's enemies, Wong hoped that Strange would be able to help her. Strange was having problems of his own at the time, and Wong took this as a sign that Strange wouldn't be able to help Imei. This resulted in the first friction between the Sorcerer Supreme and his old friend. Finally, Strange managed to redirect some attention to this matter, the magical probe revealed that the demon just acted like Imei. In fact, he discovered that it wasn't Imei at all, but only a construct that was made to believe it was and that the true Imei had been killed. Although Wong was as yet unmarried and childless, he has stated that his first-born son would follow the family tradition of serving a mystic devoted to good.
This incident caused Wong to become mentally unhinged. For a while he operated as a staunch opponent of Strange, allying himself with other forces in order to battle him. The two eventually made their peace, re-establishing their old relationship. Said relationship then changed for the better, as both tried to treat each other as equals, instead of master and servant.
Sometime before the beginning of Civil War, Wong discovered he had developed an inoperable brain tumor. He tried to conceal his condition from Strange, but the sorcerer found the medicine he had been using to mitigate his symptoms. Doctor Strange found and battled the demon-god Otkid to retrieve Otkid's Elixir, a magic potion which had the power to "erase what troubles the mind of man" and which was in fact the cure for cancer. After some misadventures, Strange spent the last remaining drop of Otkid's Elixir to save Wong's life.
Following the Civil War, the New Avengers, a small group of super heroes who had gone underground in protest of the Superhuman Registration Act, took refuge in Doctor Strange's home. Wong served them just as ably as he served Strange, albeit with some grumbling at their treatment of his kitchen. But when the New Avengers left the Sanctum Sanctorum (shortly after Strange himself left, having surrendered the position of Sorcerer Supreme), Wong did not go with them.
When Doctor Strange rejoined the Avengers, he suggested hiring Wong as cook and housekeeper for Avengers Mansion. Though he groused at becoming "a second-rate Jarvis for a second-rate pile of Avengers," Wong accepted the position.
Leaving Dr. Strange
Having remained by Strange's side as his master regained the title of Sorcerer Supreme and returned to the Sanctum Sanctorum, Wong eventually departed after having a falling out with Stephen over the doctor's method to saving the life of their ally Zelma Stanton, who was fatally ill after transferring the effects of a deadly poison from Strange to herself in order to save his life. Having devoted his entire life to the ways of magic, Wong set out to build a life of his own.
- Sorcery: Despite originally stating that he has "no powers of sorcery, black or white," he seems to have become a competent sorcerer since then. Wong has been deemed sufficiently worthy to be one of dozens of candidate for the vacant role of Sorcerer Supreme by Agamotto through his Eye (though Wong failed to inherit the title from his master in favor of Brother Voodoo). Wong also appears to be now skilled in uttering mystic incantations sufficiently accurately, as he did so while reading from a spellbook in an arcane language not of his mother tongue or English through the Orb of Agamotto when the Sorcerer Supreme was stabbed in Japan while working with the New Avengers.
- Martial Arts: Wong is an expert in the martial arts of Kamar-Taj, achieving great mastery over it, although he has rarely used them in recent years. Hence, although Wong can overpower many adversaries, he is no longer a match for a master of the martial arts who keeps himself at or near peak condition; Wong has even been shown capable of directly driving off the likes of the Nisanti demon-enhanced the Hood in moments through sheer will and physical prowess, despite Robbins having the advantage of surprise, the guidance of Dormammu and a formidable gun capable of firing bullets splashed with demonic fire.
Wong's skill in magic, even recently, is nowhere near that of a truly adept mystic. He would be at a disadvantage while confronting a superhuman, whether versed in occult means or not.
