The space pod touched down on the green land. Where is he? Tarble thought. Come on big brother. I know you're here. He used his scouter to try to find the Saiyan prince. 5 power levels. North. One of them has got to be Vegeta. The young Saiyan flew off. Haven't seen you since I was young. Here I come.
Authors note: Tarble's date of birth or even year hasn't been confirmed. It's assumed he's older than Goku but younger than Vegeta. So that's the case in this reality.
