Sun Wukong and the Were-Monkey Macaque

Origin: Born from a magical stone egg on the Mountain of Flowers and Fruits, absorbing the power of heaven and earth. Path to Power: Became the Monkey King, mastered the art of immortality, the 72 transformations, and the ability to fly on the clouds. Rebelled against Heaven and, after defeating Buddha, was imprisoned beneath the mountain for 500 years. Main Mission: Became the faithful protector of the monk Xuanzang on his quest to India to acquire Buddhist sutras. At the end of his journey, he received the title of Buddha. Weapon: The heavy staff "Ruyi Jingubang," capable of changing size.

Origin: A mythical creature with perfect pitch ("hears everything within three thousand li"). The macaque's appearance is a mirror image of Sun Wukong, his evil double or shadow self. Biography: Appeared when the monk Xuanzang once again became angry with Sun Wukong and drove him away. The macaque assumed Wukong's form, beat the monk, stole his luggage, and created a fake team of companions so he could independently go and retrieve the sutras and take Wukong's place.
and the mask also knows everything

Conflict and Death: No one could distinguish the impostor from the true Monkey King—even the mirrors of the gods and the magic of the bodhisattvas demonstrated absolute identity. Only Buddha Shakyamuni resolved the dispute. When the true Wukong struck him with his staff, the monkey attempted to fly away, but was caught in the Buddha's cup and killed by Sun Wukong. Character Comparison
Essence: Sun Wukong underwent purification and redeemed his pride through service, while the Six-Eared Macaque embodies envy, greed, and the desire to obtain others' merits through deception. Meaning: Their battle is an allegory of the internal struggle of a tamed consciousness with the remnants of the ego.
