The Warrior Dragon is a curio shop appearing in the Teenage Mutant Ninja Turtles Magazine story of the same name. In the story, the Turtles enter while looking for a gift for Splinter, and to get out of the rain. The Turtles and the shopkeeper discuss a potential gift, with Mikey suggesting a dragon-shaped jar, and the shopkeeper saying it's not for sale and suggesting a flat-bottomed wok that can make egg rolls or pizza instead.
Just then, a gang of thugs barge in, demanding "protection" money from the shopkeeper. The Turtles attack the thugs, but the shopkeeper interrupts them by throwing the dragon jar to the ground and unleashing a Warrior Dragon that scares off the thugs. After they leave, the Leo then suggests they get back to the discussion of the demonstration of the wok.
