Sun Wufan is the protagonist in Toriyama Akira's Dragon Ball and the eldest son of the Monkey King. He has great potential, but his character is not as belligerent as that of a purely Saiyan fighting nation like his father. He studied diligently under the guidance of his mother Qiqi since childhood, and his dream is to become a scholar when he grows up. Kind and brave, don't like fighting very much, but when angry, they will exert great strength. When I was a child, I shouldered the heavy responsibility of repelling Saiyans and protecting the earth. When I was only 4 years old, I was forced to leave my family and practice martial arts in the wilderness with my bike. They have established a deep affection.

Later, he went to Nami to fight against Felisa, the great universe. In a state of anger, he beat Felisa and forced Felisa to complete his last transformation. When the artificial man attacked, he went to the paranormal time house to practice with Wukong. In extreme anger, he became Super Saiyan 2, defeated the artificial man Shahru and surpassed his father. Seven years later, in the battle with the magic man Buo, he showed his full potential under the guidance of old Kaiōshin and became one of the strongest fighters in the universe. After the defeat, Magic Man Buo married his high school classmate Videl, concentrated on his studies and lived a quiet life. 10 years later, he became a famous scholar and had a daughter, Xiao Fang.

Toriyama Akira wanted him to replace his father as the leading role, but the Monkey King was too deeply rooted in people's hearts to succeed. In addition, Gofan's name comes from Sun Wufan, an earthman who adopted his father Wukong.
