Sha Wujing appears as a man-eating ogre dwelling in a castle who ambushes the pilgrims. He attempts to consume Sanzo and Cho Hakkai but is defeated in combat by Son Goku. Following his defeat, he joins the pilgrimage to the west.
His monstrous design reflects his cannibalistic nature. He wields a distinctive moon staff, a long weapon featuring a half-moon blade, consistent across portrayals.
During the group's clash with the Bull Demon King at the Flaming Mountains, he participates in rescue operations alongside Son Goku and others. He aids in freeing the captured pilgrims after their imprisonment for a planned demon feast. His actions contribute directly to the Bull Demon King's ultimate defeat.
The English-language adaptation alters his name to Max Lulipopo, emphasizing a more comedic interpretation. This version omits his original backstory as a banished celestial general who broke a heavenly artifact. The symbolic skull necklace and elaborate mythological context surrounding his river dwelling and punishments are also absent.
His narrative function centers on providing physical strength within the group and participating in combat against later antagonists. He completes the journey to the western paradise alongside the other pilgrims and receives the sacred sutra from Buddha.
The character appears solely in this single film within the animated adaptation's media.
