The main plot of North Kaiō

The Monkey King and Raditz died in World War I, and the immortal recommended Wukong to practice in North Kaiō to deal with the two Saiyans who arrived a year later. The Monkey King came to North Kaiō's planet through the snake road and asked North Kaiō to teach him martial arts. The Monkey King's joke successfully amused North Kaiō, so the Monkey King practiced on earth, and the king of the northern territory taught the Monkey King his unique skills: Wang Jie Boxing and Yuan Qi Bombing.

After World War I, Bick, Tianxington, Leping and Jiaozi were all killed. In order to revive them, Bulma, Kobayashi and Sun Wufan went to Nami Nemesis to look for the Dragon Ball, and then the Monkey King also set out. On the planet Nemesis in Nami, they clashed with the cosmic emperor Felisa and his men. On the other hand, Bike, Tianxintang, Leping and Jiaozi also successfully passed the Snake Road and got the guidance of North Kaiō. The bicycle passed through North Kaiō, which made the beautiful Nemesis Lomborenga send him to fight in the beautiful Nemesis. In the final decisive battle between the Monkey King and Felisa, the king of the northern territory watched the battle with Tianxintang, Leping and Jiaozi. The King of the Northern Boundaries talked telepathically with the elders of Nami's nemesis, and wanted the Dragon to transfer everyone to the earth except Felizaz, but the Monkey King insisted on winning with Felizaz.

On May 26th, 767, the Battle of Shahrukh began. In Sharu's game, it became Super Saiyan 2. Sun Wufan defeated Shahrukh, and Shahrukh spat out the artificial man 18 and changed back to the second form. Desperate shah rukh was forced to die with the earth with the idea of self-destruction. At the critical moment, Wukong teleported himself and Sha Ru to Wang Xing in the northern boundary, and North Kaiō died in the self-explosion of Sha Ru and Wukong. After Sun Wufan destroyed Charouk, people hoped that the Dragon would resurrect the Monkey King, but the Monkey King declined politely. Neither the king of the northern boundary nor his pet was resurrected to accompany the Monkey King.

In the final decisive battle between the Monkey King and Magic Man Buo, the Monkey King used gas bombs, while Vegeta sent a message to the people on earth through North Kaiō, asking them to contribute their strength. With everyone's efforts, the Monkey King destroyed the magic man Buo with gas bombs. In "The Master of the Galaxy Facing Crisis", the king of the northern boundary, the king of the east, the king of the south and the king of the west joined hands to seal the universe thug Bojack on the planet at the end of the galaxy. However, due to the death of the northern border king, Bojack and his followers lifted the seal.

In "The Condor Heroes", the virus of the God of Destruction competed with the Monkey King, the Super Triumph, and claimed that it lost hide-and-seek with North Kaiō, destroying half the world.
