When things became too much for Dax and Drake in their fight with Drake's uncle, they talked about the potara earring fusion. While they were talking, Gotan was charging a Spirit Bomb while Goten fought Drake's uncle. It was decided. Dak was born. Drake uncle was close to losing, but he was the power level of a Legendary Super Saiyan 3 at base and he can go Legendary Super Saiyan 6. So Goten and Dak had to fight him. Dak seemingly died in rage. Goten went Dark Super Saiyan, and Gotan finished the Spirit Bomb. And then he threw it at Dak. 3 weeks passed since then, and and the two separated from Goten cosmic gands after cosmic Kamehameha. They yelled all day after that painful pull. THE END.
