2539. Master Mantis

Master Mantis is the smallest of the Five, but he is obviously the strongest proportional to his size. He can perform such feats as throwing Po and single-handedly holding up a severed rope bridge burdened by most of his comrades and Tai Lung and still have the strength to snap the bridge when needed. He is also a skilled acupuncturist, although his success does depend on the type of body he is working with; a body like that of Po or Viper can sometimes give him problems until he familiarizes himself with the particular anatomy. Pragmatic and open minded with a dry sense of humor, Mantis was the first of the five to develop acceptance and liking of Po as a person, alongside the factor of Po's girth, declaring size did little to define a warrior and could actually be used as an advantage no matter what style one practices. An unused line from the movie is Mantis saying, "I've got to admit, that panda has a lot of heart. And he's incredibly fun to watch bounce."
When he was a few years younger (in Secrets of the Furious Five), Mantis was extremely impatient, feeling that the world was too slow for him and he was too fast for the world. On a mission to retrieve wool coats back from the Wool Stealing Crocodile Bandits, he was captured due to his overconfidence and lack of listening skills when one of the sheep villagers tried to warn him of the bandits' traps. Mantis was locked in a cage for days and forced to sit and wait for something to happen, and he entered a trance that allowed him to survey the world moving faster than he did. This allowed him to develop the patience needed to devise a plan of escape, playing dead to trick the crocodiles into opening his cage and defeat them.
In the sequel, Mantis' background is further revealed. When the group interrupts Po and Tigress in an effort to give "emotional support," Mantis says wistfully that he never got to know his father, because his mother ate his father's head. Later, when it seems as if they are about to die, Mantis sighs that he always expected to settle down with "a nice girl who would later eat my head."
Mantis is also shown to be able to move at inhuman speeds and break metal with his super strength.
