Sun Wukong, the Monkey King
A legendary figure best known as one of the main characters in the 16th-century Chinese novel Journey to the West (西遊記/西游记) and many later stories and adaptations. The Monkey King's origins predate the novel and can be traced back both to the Monkey-God, Hanuman, from the Hindu epic, the Ramayana as well as from the Song dynasty. In the novel, he is a monkey born from a stone who acquires supernatural powers through Taoist practices. After rebelling against heaven and being imprisoned under a mountain by the Buddha, he later accompanies the monk Tang Sanzang on a journey to retrieve Buddhist sutras from the West (India) where Buddha and his followers reside.
