There isn’t any martial arts for Wong in Doctor Strange actually, he’s more of a drill sergeant to Kamar-Taj.
However, when Doctor Strange comes out later this year, that version of Wong won’t be relegated to being Stephen Strange’s manservant, instead being more of an authority figure.
For one thing, he and Benedict Cumberbatch are about the same age, whereas Wong in the comics is younger than Stephen Strange.
Doctor Strange may be the Master of the Mystic Arts, but in the Marvel comics universe, he wouldn’t be nearly as successful in his endeavors without the assistance of Wong.
