A warrior from an early age, Mantis had a fast-paced attitude that led him into trouble when he was captured by the Wool Stealing Crocodile Bandits. Forced to stay still for many days, he learned the patience needed to free himself. After learning this kung fu discipline, he eventually came to form the Furious Five with Tigress, Monkey, Viper, and Crane. Upon meeting Po, he made light of the panda being the Dragon Warrior, but was one of the first to relate to him. He now fights alongside Po as a friend and ally.
