Phase Four- Is Chang Shi's Vivian The Mandarin?

*Contains Spoilers To Iron Man 3

Chang-Shi And The Legend Of The Ten Rings is a MCU film that we are ALL excited about. A fan theory suggests that the villain will be one that we are already familiar with. If you have watched Iron Man 3, you know that The Mandarin was a life-taking villain who really just turned out to be a goofy actor, faking all the things people thought he was really doing. With the addition of Fire people and a few other weapons to threaten with, it was very hard for Iron Man to defeat him, especially when Pepper Potts, his wife, was infused with the fire serum. This fan theory say that the Mandarin is the villain of this movie, makes sense, right?
