Sun Wukong is a famous character across East Asia, including China, Korea, and Japan, where he is known as Son Goku.
As a legendary Chinese deity, his original story has several different versions. The most popular version is the story revealed in the classic novel Journey To The West. In this novel, Sun Wukong came out from a rock as a monkey-shaped creature. He becomes the leader of a monkey tribe and titled himself, Monkey King. He then decides to learn magics from an immortal saint, and it turns out that he is a quick learner.
He mainly learns immortality, invincible (his body became impenetrable like metal), flying by driving clouds, and the 72 transformations that allow him to shapeshift into 72 different objects (possibly more). He also is given the name Sun Wukong which means understanding the essence of emptiness.
After he mastered all his magics, he dives underwater to seek the dragon king of the east sea to borrow a weapon that matches his strength. Dragon king introduces him to a gigantic pillar at the bottom of the sea, thinking Sun Wukong won't be able to lift it. It turns out that this pillar is a magic pole that can change its size according to the owner's wish. Sun Wukong successfully controls this weapon and claims it as his own. Dragon king regrets his decision and reports to the emperor of heaven to catch Sun Wukong.
Sun Wukong turns against the whole heaven, and he single-handed defeats most deities, forcing the emperor to call the Buddha for help. The Buddha throws a mountain at Sun Wukong and uses a spell to make this mountain unmovable, keeping the Sun Wukong a prisoner under the mountain.
500 years later, Sun Wukong is released by Xuanzang to be his protector on the journey to the west for exchange. Xuanzang is given the mission from the Chinese emperor to reach the land of Buddha in the west to collect sacred scriptures. Sun Wukong slays demons who threaten Xuanzang on the journey and finally ascended as the god of war (or the Buddha of war) after he finished his mission.
Sun Wukong was the inspiration behind the character Son Goku, from the Dragon Ball franchise of Japanese manga, anime, and games. In turn, Sun Wukong himself is believed to have been influenced by the Indian Hindu mythological character Hanuman.
In video games, Sun Wukong has appeared in a number of East Asian video games, as well as a few Western video games, such as Enslaved: Odyssey to the West.
