While trying to reach the Fire Temple in time for the winter solstice, Team Avatar attempted entry into the Fire Nation by air, but they encountered the blockade and were consequently fired upon by order of Zhao, a commander at the time and in charge of the blockade. The fact that Prince Zuko was also in pursuit of the Avatar and about to be caught in the attack was of no concern to Zhao, not only because of their rivalry, but also because Zuko was banished from the Fire Nation and was not permitted in Fire Nation territory. During the attempt to stop Team Avatar's advance, the engines of Zuko's ship were badly damaged by a fire ball. When Team Avatar managed to pass the blockade, Zhao allowed Zuko to pass through as well in the hopes he would lead him to the Avatar's destination.
