"They Say Robot's Can't Drown. Let's Test That!" Mega Water S (メガウォーターＳ Mega Wōtā S) is an amphibian Robot Master from Mega Man: The Wily Wars with a kappa appearance. He is based on the river sprite Sha Wujing, a character from the Chinese novel Journey to the West. He is the smartest of the three members of the Genesis Unit and is in charge of brain labor, but lacks confidence in himself. He has antipathy towards Buster Rod G. Mega Water S is a kikokushijo expatriate, and due to this he has a strange Japanese accent. Being based on a kappa, he has a liking for shirikodama, and dislikes raw fish (his localized CD data contradicts this, stating that he likes sashimi).
