The main protagonist of the famous novel: Journey to the West. An unnamed monkey born from a huge rock. After he has mastered 72 marvelous magic skills he names himself "Sun Wukong" (孫悟空, translates to "Son Gokū in Japanese). "Sun" is a common Chinese surname, and "Wukong" is a Buddhist given name meaning "awakening to emptiness", given to him by his master Bohdi who taught him the said magic skills. He violates everywhere he pleases such as the hell for extending his lifespan and Celestial Court for stealing the Peaches of Immortality, and thus before the novel starts, he was well known for causing havoc that shook the heavens through his rebellious attitude, but has a notable soft side and cunning, confident exterior.
"Seiten Taisei" is the Japanese translation of the Chinese name "Qitian Dasheng" (齊天大聖) which translates to "Equaling Heaven Great Sage", a title Sun Wukong placed on himself when trying to win the respect of the heavens the second time by force. After his attempt to insult Sakya he is imprisoned under the Five Finger Mountain for 500 years until he is freed by Xuanzang and joins his journey towards Tianzhu with two other companions.
It is believed that Sun Wukong's creation by the author of the book, was heavily influenced by the Hindu monkey god, Hanuman.
Wu Kong can be obtained by evolving a Hanuman at level 50. Unlike Kurama and Queen Mab, since Hanuman can only be obtained by evolving Onkot and he never appears in any normal battle (Genma and Fury race demons never responds to negotiation in battle anyway), making Wu Kong the only demon in the game which requires secondary evolution to obtain.
Save for the Fiend demons, Wu Kong has the above average resistance attributes including immunity to physical without weakness (the others being Girimehkala and Albion). The only hindrance of his usefulness is that his repertoire of skills lacks any magic spell. The only way to redeem it is to fuse an Onkot with some magic spell (Elec spell is recommended against Rangda) and retain those spells during level up until Wu Kong succeeds them.
Shin Megami Tensei IV
Wu Kong is a boss in the Challenge Quest, Capture the Berserker. It is given to Flynn when he talks to demons in Naraku, with the actual client being Kishin Erlang Shen.
The quest description recalls Wu Kong's mischief, and he has made a link from the Heavens to Naraku. After he escapes from battle two times, the third time is where he gets tired of Flynn's meddling, and fights seriously. After this he surrenders and reveals he was expecting a God to beat him and not some mortal. Regardless he lost so he returns to the heavens. Flynn then receives the Tokkosho sword as a reward.
