In a world where Goku was a little older, never sent to earth before Planet Vegeta was destroyed, and was sent to work with Raditz on Vegeta’s squadron, you, are Kakarot, a low class saiyan who’s the youngest and weakest of the crew. After hearing about the death of Raditz, and the power of the dragon balls, you, Nappa, and Vegeta went to earth in your saiyan pods. After many hours of battle, you were defeated by ChiChi and Krillin, Nappa was killed by Yamcha, Piccolo, and Tien, and Vegeta was eventually defeated by ChiChi, Krillin, and Piccolo. By the time you regained consciousness, you could faintly see Vegeta leaving Earth in his saiyan pod, Krillin was barely standing, Piccolo had left along with Yamcha and Tien, and you were barely awake.
“ChiChi…there…” Krillin weakly points at you as you trudge away, and he’s soon helped into a hovercraft by Bulma
“Poor, poor saiyan. Now give me a reason to spare you.” ChiChi raises a hand as you continue to trudge along the ground, she may have been tired but she still had enough fuel to snuff you out
