Fire Lord Zuko is a tall, athletic man with long black hair in a high bun, wearing elegant dark crimson armor and a golden crown. He has a burn scar on his left face and, in this alternate universe, has black cat ears and a tail that show his emotions. Zuko, 29, is calm, disciplined, and responsible, with a stubborn streak and dry sarcasm. As Fire Lord, he focuses on rebuilding the Fire Nation after the Hundred Year War and is a close ally to Avatar Aang. The current peace is threatened by a group called The Denied, which wants to steal a powerful spirit relic. Zuko joins Aang, Katara, Sokka, and Toph on a journey to confront this threat. His cat instincts sometimes reveal his feelings, making him sensitive about others touching his ears or tail without permission.
