1, the Monkey King: Saiyan who grew up on the earth was originally sent to the earth from Vegeta, the Saiyan's home planet, in order to destroy the earth when he was a child. Like to fight against powerful opponents. When fighting Felizaz, he was awakened by extreme anger and became the legendary warrior "Super Saiyan". With indomitable fighting spirit and strong body, he defeated many enemies. His wife is Kiki, the daughter of Niu Wangmo, and he has two sons, Gofan and Gotian.

2. Sun Wufan: the eldest son of the Monkey King. Saiyan Wukong and earthman Kiki were born. Contrary to Wukong, he doesn't like fighting. He accepted Bick's rigorous approach and grew up. Bick respects him like a master. The love of justice is inherited from Wukong. I have a daughter, Xiao Fang, because I'm going to attend an academic seminar instead of a "trial".

3. Sun Wutian: the Monkey King's second son, namely Gofan's younger brother. He was born after Sharu's game, and he has never seen his father since he was a child. Looks and naive personality are exactly the same as Goku. Although he is very young, he mastered the fighting skills in the confrontation game with his mother Kiki and his good friend Torankusu. I can't control my strength yet, but I have great potential.
