[MCU] Okay, I finally saw Shang-Chi. What was the dragon he rode out of the sea? I am totally in the dark with this guy.

A quick bit of info might be nice.

That dragon is the Great Protector that they were talking about earlier in the film, though she doesn't have any other name that we're privy to at this time.

There are some rough equivalents in the comics, though you may as well look into the Chinese Dragons, also known as Lung Dragons, for more information.
