The Fire Nation circus was a group of traveling performers that gave demonstrations in various Fire Nation colonies in the Earth Kingdom. The circus entertained Fire Nation and Earth Kingdom families alike by hosting acts from rope walkers, acrobats, and plate jugglers. It also featured a large collection of rare and exotic animals, including a lion vulture and at one point a "wind buffalo".
After the capture of Omashu, PrincessAzula visited the circus, searching for her childhood friend Ty Lee, who had been employed there as a tightrope walker. After Ty Lee declined Azula's invitation to join her mission to capture Zuko and Iroh, the princess asked to see one of her performances. The circus hosted a private show in her honor, featuring an acrobatic performance by Ty Lee, who walked the tightrope over a burning net while the circus' wild animals ran loose, circumstances initiated by Azula's orders. After this terrifying experience, Ty Lee decided to resign from the circus and join Azula on her quest.
