All the Buddhas have witnessed the passing of time, yet Wukong alone remains trapped in his own mind.

Did Sun Wukong become a Buddha?
Sun Wukong eventually became a Buddha and was named the Victorious Fighting Buddha.
In the story of Journey to the West, Sun Wukong undergoes a transformation from a mischievous stone monkey to the Great Sage Equal to Heaven, and then endures eighty-one tribulations while escorting Tang Sanzang on his journey to the West to retrieve Buddhist scriptures. He ultimately achieves enlightenment and is bestowed the title of Victorious Fighting Buddha by the Buddha. This title symbolizes his triumph over afflictions and obstacles, reaching a state of enlightenment and liberation, thus completing the highest level of elevation for this literary character.
