Shang-Chi and the Legend of the Ten Rings will introduce the titular character Shang-Chi, a superhero with incredible martial arts skills. He's referred to as the "Master of Kung Fu" and has complete mastery over his chi, so it's easy to think the character's Marvel Cinematic Universe movies will be typical martial arts offerings. However, there's a very good chance that they'll be much more than that. because in the comics, Shang-Chi has a longstanding association with the British spy organization MI-6. This means the movie character could become Marvel Studios' very own James Bond.
The character first appeared in 1973's Special Marvel Edition #15 (by Steve Englehart, Jim Starlin and Al Milgrom) as more of a wandering martial artist than a secret agent, but he went on to become heavily involved with MI-6 in many of his stories following his introduction.
Shang-Chi first officially worked with MI-6 in 1976's Master of Kung Fu #42 (by Doug Moench, Paul Gulacy and Tom Sutton), when he accompanied Black Jack Tarr on a mission to track down a group of criminals known as the "Oriental Expediters." He underwent vigorous training with the organization and therefore is very familiar with a variety of espionage tactics and methodologies, just like a certain Mr. Bond is.
He went on to ally with MI-6 in taking down the likes of Welsh dragon who had taken human form as a Welsh mob leader, as well as his own half-brother, Moving Shadow, but his most notable and persevering work with the British intelligence organization was helping them take down his own father, the villainous Fu Manchu, preventing him from taking over the world.
Shang-Chi's association with MI-6 in the comics is strong evidence that he could become the MCU's James Bond. Additionally, rumors and news surrounding his upcoming movie further this argument. First, Shang-Chi's dad will be the Mandarin instead of Fu Manchu, given that the character is an extremely problematic racial stereotype. Regardless, Shang-Chi having a villainous father suggests this part of his comics identity will appear in the franchise.
Second, according to Murphy's Multiverse, the movie may introduce comic book characters Leiko Wu, Black Jack Tarr and Clive Reston (the latter of whom was hinted as being the son of James Bond in one story) to the MCU. All three of those characters are MI-6 agents strongly associated with Shang-Chi, and Leiko Wu potentially provides him with a badass James Bond-esque love interest, as she has in the comics.
Additionally, Shang-Chi himself is expected to be introduced to movie audiences as a former MI-6 agent who has since moved on from his life as a spy. Therefore, it can be assumed that the reappearance of three of his former colleagues will result in him being dragged back into that world. If that's the way Marvel Studios is taking the character's movie franchise, things could get interesting really fast. Hollywood could finally have a non-white Bond-esque character.
