Let me tell you that Sun Wukong is not a character created by the author, but is integrated through some other characters. To put it simply, there are some character archetypes. Speaking of which, there are actually quite a lot of prototypes of Monkey King, which you can understand as an alternative stitching.
Wuzhiqi: Huai River Water Monster.
First of all, let me tell you that Wuzhiqi is one of the prototypes of Sun Wukong. Therefore, because of the existence of this prototype, it has a certain relationship with the Ruyi golden hoop stick. We know that when Dayu controlled the water, this monster came out to make trouble when he was fine. And the power of this monster can be said to be quite large.
Within a thousand miles, the wood charm, the water spirit, the mountain demon, and the stone monster all obeyed his orders and were subject to his control.Therefore, such a character prototype, you can correspond to Journey to the West, that is, the demon king who subdued the 72 holes. In addition, it has a certain relationship with heavy rain, so it is also related to the Ruyi golden hoop stick of the Dragon Palace in the East China Sea. Let me tell you, theoretically speaking, this guy should still be suppressed in the Huai River. By the way, let me tell you about this character, in fact, he was the first scene in Journey to the West, and his name is Ahuizotl.
As for the time of appearance, it was in the disaster of Xiaoleiyin Temple that Sun Wukong went to ask for help. The other party said that the Ahuizotl Great Sage was in turmoil, and he needed to suppress him. There is no kung fu to help Sun Wukong subdue demons.
Indian Monkey? 
There is another archetypal character, which is that he is a god monkey of India, and we can see how such a character is recorded in the books.
Its face and body can change at will, and it can move mountains and seas.It can be seen that there is a word change that stands out here. One of Sun Wukong's biggest skills should be the so-called 72 changes, so is such a character archetype overlapping in an instant? And in Journey to the West, Sun Wukong's strength is also quite large, and he should also have the ability to move mountains and reclaim the sea. Especially in the case of the Golden Horn and the Silver Horn. Sun Wukong ran fast directly on his back against the two mountains. Theoretically, this should also be one of the prototypes of Monkey King. But to be honest, the presence of this archetype is not particularly high, at least what people on our side know is not particularly clear, after all, it is an Indian monkey.
Shen Yang Gong. 
knows that Sun Wukong is the Monkey King, and there are many sworn brothers. So such a character archetype should correspond to Shen Yanggong, which should also be a monster in ancient China, what kind of ability does this monster have? In the book, there is not too much description of his ability, focusing on describing him as a perverted monkey. If you read Journey to the West carefully enough, you will find that in many details, you will see that Sun Wukong seems to be very lustful. If it is in the original book, there is not a single piece of evidence.
It's because when the author wrote this character, he corresponded to this monster, but he didn't write his deeds in the book. By the way, in the end, this monster was suppressed by Erlang God, and there was no need for the Buddha to take action.
The archetypal synthesis of the Monkey King.
Therefore, Sun Wukong should be regarded as a complex, many characters, his character and experience have been adapted to a certain extent, and then put it on Sun Wukong's body. Because the author wants to make a perfect monkey, he removes the shortcomings of these characters. And at the same time, the advantages of this character have been infinitely magnified, and it has become a Monkey King we see now. Especially the part of love, put all this shortcoming on Marshal Tianpeng Zhu Bajie. It can only be said that this way of writing is indeed quite common, after all, the protagonist must not have any moral flaws.
