Fics like Flint and Steel

The bald man grabbed Sokka by the throat, but his grip went slack when he heard shouts of alarm from his companions. Sokka began to laugh. Fire Lord Zuko stood in the center of the road, eyes blazing almost as bright as his fists. A red dragon stood shoulder height to him, tail swishing and teeth bared. They looked like two iterations of a dangerous spirit, blessed by the sunset behind them. Smoke escaped both of their noses. When Zuko spoke, his harsh words were accompanied by a lick of flame. “Take your fucking hands off my husband.”
