Izuku/Zuko : The Avatar

In this story Ang would die in the ice and Zuko would be born the Avatar. No one knows this until he is burned by his father. When his father burned him instead of just crying he got pissed and used all the elements at once even gaining access to lightning and blood bending then his body was engulfed in white he woke up in the woods and was found by inko midoriya. Also I am making him seven when he was burned because I need a reason for him to actually like inko as a mother.
