Who is the fake Sun Wukong?

The fake Sun Wukong appears in the classic Chinese novel Journey to the West, specifically during a sequence where Sun Wukong faces a series of challenges and confronts a false version of himself. This fake Sun Wukong is not a true reflection of his character but rather a doppelgänger created by the Taoist immortal, Prince Nezha, or a trick played by other forces like the White-Bone Demon (Baigujing).

One of the most notable instances of a "fake" Sun Wukong occurs when the White-Bone Demon (Baigujing), in her attempts to deceive the monk Xuanzang and capture him, transforms herself into a fake Sun Wukong to trick the real Wukong. In this scenario, the White-Bone Demon uses her shapeshifting abilities to impersonate Sun Wukong, and it takes the real Wukong some time to detect the deception. This moment is significant in the novel because it illustrates the trickery and illusion-based powers that enemies of the monk can use to confuse the protagonists.

Additionally, there is another storyline where the Buddha or celestial beings create illusory versions of Wukong in order to test his resolve and purity of mind. These "fake" versions of Wukong are not true duplicates in power or essence but are magical constructs intended to challenge the real Sun Wukong.

Summary: The "fake" Sun Wukong is typically an imposter, often created by shape-shifting demons or supernatural forces like the White-Bone Demon, or even celestial beings testing his resolve. While these fakes can mimic Wukong's appearance or actions, they lack the true power, spirit, and cunning of the original character.
