Sha Wujing
In Japan he was popularly seen and depicted as a kappa, another fearsome kind of water demon.
In the manga/anime Saiyūki, Sha Gojyō is loosely based on Sha Wujing, with a modified version of the same weapon (albeit incorrectly called a shakujō, the Japanese name for the Chinese xīzhàng). However, Gojyō is described as being half human, half yōkai with the ability to breathe underwater, instead of a man-eating river monster.
Mega Man: The Wily Wars had a character based on Sha Wujing named Mega Water.S in the unlockable "Wily Tower" game. Mega Water.S later made an appearance in the CD Database for Mega Man & Bass.
In the manga/anime Dragon Ball, the character Yamcha, the Desert Bandit, was originally based upon Sha Wujing.
There is a Digimon called Shawujingmon.
