Master Croc is a master of kung fu. He was the former leader of the Wool Stealing Crocodile Bandits, now having turned over a new leaf as a member of the Kung Fu Council. Croc's origins are currently unknown. However, it is known that he was once the head of the infamous Wool Stealing Crocodile Bandits of Crocodile Island, a gang of criminals noted to be "unmatched in their mischief" and known for their skill in trap-setting. One such trap successfully captured Master Mantis, though the bandits themselves were eventually fooled by his "staying-still-for-a-really-long-time" technique. It is also known that Croc eventually crossed paths with Master Thundering Rhino, whose kung fu was proven superior in their battle on the shores of the Wa Su Li River. Beaten, Croc prepared himself for death, but the fatal blow never came. Thundering Rhino instead asked Croc to use his kung fu skills for doing good. Croc was so moved by Master Rhino's compassion that he immediately quit his criminal ways. He then traveled across China, following Rhino's advice to use his kung fu for good by righting wrongs and protecting the weak. Croc gained fame for his victorious deeds during this time. One such victory was his silencing of the Badger Bandits, who insulted Croc by talking about his mother. Eventually he came to sit at Rhino's side as a member of the Kung Fu Council.
