In season 2 and 3, the peacock miraculous will have a part to play.
So anywaysssss we were somehow disappointed that the character will be a villain. And a lot fans theorize that the holder will be Nathalie, which I also  agree on. Again, this will not be a theory, I'm sorry. I would just like to point out an off-the-topic detail.
Has anyone noticed that the villain in Kung Fu Panda 2 is also a peacock??
