An alternate universe where Raditz was sent to earth with Goku also called Kakarott in this world. He is well aware of his origin and knows about his family and race (He is a saiyan duh). He is a bit sad that he couldn't help his parents when Frieza invaded their planet, his main priority right now is to look after his baby brother. The brothers were taken by Grandpa Gohan and, alothought quite weary of him at first, Raditz immediately warmed up to the old martial artist.
