The Real Monkey King was a Chinese martial arts novel that told the story of Sun Wukong and the Bull Demon King. The main plot of the story was as follows:
Sun Wukong was the Monkey King of the Flower-Fruit Mountain. He had become a member of the Immortal World because he had eaten the immortal peaches of the Taishang Laojun. Later, he was given the title of "Great Sage Equal to Heaven" by the Jade Emperor and was forced to live under the Five Fingers Mountain for 500 years. During this time, he got to know Princess Iron Fan, Bull Demon King, and others.
Five hundred years later, Sun Wukong was recruited by Tang Sanzang and decided to go to the Western Paradise to obtain Buddhist scriptures. Along the way, he had a series of fights and adventures with Bull Demon King, Princess Iron Fan, and the others. The real Monkey King incident was a conflict between Sun Wukong and Princess Iron Fan.
The fake Sun Wukong was disguised by Zhu Bajie and Sand Monk, the disciples of Tang Sanzang. They wanted to use the conflict between Sun Wukong to stop Sun Wukong from learning the scriptures. However, Sun Wukong had already seen through their plot and decided to fight them. In the battle, Sun Wukong and Princess Iron Fan joined forces to defeat the fake Sun Wukong, but there was a more complicated conspiracy behind the fake Sun Wukong.
In the end, Sun Wukong successfully defeated the conspiracy of Princess Iron Fan, Zhu Bajie and Monk Sand through his wisdom and courage and successfully arrived at the Western Paradise to learn the scriptures. In this process, he gradually understood the true meaning of life and the way of life.
The Monkey King has many adventures. For instance, he rebels against the Jade Emperor in heaven. He fights against various powerful deities there. Then, during the pilgrimage to the West, he uses his magical powers like the 72 transformations to overcome difficulties. He also battles with powerful demons such as the Bull Demon King. His adventures are full of challenges and his cleverness and strength are constantly tested.
The Monkey King is extremely powerful. He has mastered many magical skills like 72 transformations, which allow him to change into different forms at will.
Another theme could be the clash of different universes. Amazo is from the DC universe and Saitama is from One Punch Man. Fanfics might play around with how these two different universes' rules and powers interact when these two characters meet. Also, there could be themes related to respect and rivalry. Saitama is often very nonchalant about his power, while Amazo is a complex android with various abilities. How they view each other in the fanfic can create interesting storylines.
There is actually a misnomer here as they belong to different mythologies. Hanuman is from Hindu mythology and the Monkey King (Sun Wukong) is from Chinese mythology. However, both are monkey - like figures with superhuman abilities. They are both very strong and clever, often using their wits to get out of tricky situations.
In the chapter of The Real Monkey King, there was no explicit mention of whether the real Sun Wukong was dead or not. This chapter mainly described the battle between Sun Wukong, the Bull Demon King, Princess Iron Fan, and the others, as well as the story of the Bull Demon King using Red Boy to lure Sun Wukong out.
Although Sun Wukong was an important character in Journey to the West, he had never died, so the real Sun Wukong did not die.
The Monkey King is a legendary figure in Chinese mythology. He's known for his rebellious nature, amazing powers, and adventures. He defied the gods and fought against evil to protect the innocent.
Saitama would win. He has shown incredible strength with just one punch. His power seems limitless, and in a fanfiction scenario, his simplicity and raw power would likely overpower Jiren's more complex abilities.
