The Ancient One assigns Wong to become Stephen Strange's teacher, and has helped Strange master his skills and become one of Strange's allies. Wong is an expert magic user and a master martial artist, who later becomes the Sorcerer Supreme on a technicality after Strange blips for five years.
Wong's main development is being very wise, and very serious and possessing a no-nonsense attitude. However, he is known for allocating some of his time for other activities such as listening to Beyoncé or participating in drunk karaoke. Other than that, not much else is known about his character.
Wong appears as a sorcerer at Kama Taj, where he meets Stephen Strange after his car accident and offers to help train the visitor along with the Ancient One. Wong isn't too impressed with Strange at first due to his callas behaviour and personality. Wong is also presented as very serious and doesn't understand when Strange calls him 'Beyonce'.
Following the Ancient One's death, Stephen becomes the new sorcerer supreme and Wong is his second in command. The two have since become good friends after defeating Kaecilius and Wong trusts Strange to guard the Santorum.
In 2018, Wong and Doctor Strange learn of the warlock called Thanos, when Bruce Banner crashes into the sanctorum. Wong and Strange learn that Thanos plans to erase 50% of the universe with all six Infinity Stones, called the elemental crystals. In the sanctorum, Wong meets Iron Man and Bruce Banner and eventually Spider-Man, when Greenwich Village is attacked by Thanos' henchmen Ebony Maw and Cull Obsidian. After Iron Man is saved by Wong, he invites him as a guest to his wedding and after Thanos snaps his fingers, Wong is one of the people who survives the snap, while Doctor Strange disintegrates. During this time, Wong is appointed the new sorcerer supreme for the next five years.
After Bruce Banner uses a gauntlet and brings the vanished victims of Thanos' snap back to life, five years later, Wong joins the Battle of Earth alongside the restored Avengers, including Doctor Strange. Wong brings every single superhero/superheroine to the Avengers Compound through portals, where the battle against Thanos and his army takes place. Wong later attends the funeral of Tony Stark who gave his life by snapping Thanos and his army out of existence. Wong soon after, returns to Kamar Taj to resume his duties as Sorcerer Supreme.
Wong appears in the episode "What If... Doctor Strange Lost His Heart Instead of His Hands?", where he meets Stephen Strange, who is mourning the loss of his girlfriend Christine Palmer, who is killed in a car accident. Two years later, Wong tries to help Stephen on the anniversary of Christine's death. Wong eventually learns that Strange is using the time stone to reverse the untimely event and to save Christine, but the universe is eventually destroyed, resulting in Wong's demise.
Another version of Wong appears in "What If... Zombies!?", where he has contracted a zombie virus from the quantum realm along with Doctor Strange, Iron Man and other Avengers. Wong is soon killed by the cloak of levitation decapitating him on the spot.
Since Wong survived Thanos' snap, he is now the new Sorcerer Supreme following Doctor Strange having blipped for five years between the events of Avengers: Infinity War and Avengers: Endgame. While Wong has a minor role in this movie, his memories of knowing Peter Parker is Spider-Man, are erased like the rest of the world, when Doctor Strange casts a spell for everyone in the world to forget who Peter Parker is.
Wong appears in this film, continuing his duties as the Sorcerer Supreme. Wong and Doctor Strange meet a teenage girl named America Chavez, who has the ability to travel to other universes. Wong and Strange vow to protect Chavez when they learn the Scarlet Witch wants to take America's powers to see her children again and be with them in another universe. Wong is kidnapped by Wanda and must take her to where the Darkhold is. Wong is tortured by the Scarlet Witch, but is freed when she destroys all the Darkhold's across the universes. Wong later reunites with Doctor Strange, whom respects Wong as the new Sorcerer Supreme and bows to his leader.
Doctor Strange referred to Wong as "Beyoncé", which is a reference to Beyoncé Knowles. This might also be due to the fact that Wong was heard listening to Beyonce's hit song "Single Ladies" in the film.
He shares his name with his portrayer Benedict Wong.
Wong believes there's an alternate version of himself having hair and wearing a ponytail.
