Previously, Shang-Chi and the Legend of the Ten Rings had been described as an “Asian James Bond” style movie, but with the introduction of Fin Fang Foom and the Valley containing the ancient Chinese warrior village, it seems like MCU just could not resist leaning into the well-worn Hollywood tropes regarding China, namely giant dragons, and chi-powered martial arts warriors.
We know that the Mandarin is the main villain of Shang-Chi and the Legend of the Ten Rings, and it could be that his plan is to awaken Fin Fang Foom, and use the alien beast to conquer Earth.
This valley in the comics is known to be the resting place of the giant alien dragon Fin Fang Foom, who previously arrived on Earth to conquer the planet.
While the project has been kept under wraps so far, Murphy’s Multiverse has uncovered evidence that the movie will be introducing a behemoth character from Marvel Comics, in the form of the giant alien dragon Fin Fang Foom.
