Chu Hsi was a Chinese-American firefighter who lived in New York's Chinatown district. While trying to save the life of a child he became trapped in a burning building. A mysterious curio shop owner uses an ancient relic to turn Chu into a Dragon so he and the child could escape. He had been empowered by a dragon spirit, which transformed him into the gigantic Warrior Dragon. Now that he was one with the Warrior Dragon spirit, he transformed a second time and assisted the Turtles in battling a giant Foot Soldier, which was impaled on the Statue of Liberty.
