Doctor Strange: 31 Easter Eggs & References You Must See
18. Wong
Wong is of course a character from the comics too, but he has been adapted out to a more modern, less difficult character. On the page he was a stereotypical (caricatured) servant character, capable of fighting but not magic.
Here he's still a martial arts expert, but he has been elevated to a real Sorceror able to wield artefacts and cast spells.
His comics universe father also appears - or a version of him - in the shape of Master Hamir, one of the sorcerors who the Ancient One directly addresses. In the comics, Wong's father was Hamir the Hermit, close ally and servant to the Ancient One.
