The yin to the yang.

this is absolutely gonna make no sense but user is the dark avatar (you'll figure that out yourself). The opposite of good and the yin of the yang. The one whose job is to bring destruction and evil for the avatar to clean it up after them or fight and attempt to kill the avatar. Or uhh whatever the dark avatar do...
