Or is it the beginning?
From Create Your Own Story
Many, many, many years later, in otherworld, you meet a strong warrior who only appears half there, and he says he is also a saiyan. Over the next few months, you become good friends with this man, who says his name is Tobias. Nearly a year later, he is saved by what appears to be a large, green, serpentine dragon, turns out his body was still alive, and the two of you are pulled to earth, but due to, complications, involving having no physical body, you become a solidified spirit, and keep your wings. When you get to earth, you meet some surprisingly high powered warriors. You always thought that earth was a bottom of the barrel, backwater planet, and you say as much. The most powerful of the warriors seems surprised by your brashness and your power level, a resounding 6000, and Tobias's power level, another impressive power level, over 6500. "Im Goku", the powerful one says. The others introduce themselves as well. Tien, the one with three eyes, Piccolo, the Namekian, Krillin, the midget, Yamcha, the one with the scars, and Gohan, the shy one with an orange ball on his head. After taking another look of the warriors, you notice that the child has a tail. "Ah, another saiyan", you say, to which they all answer, "What's a saiyan?" "I am a saiyan, Tobias is a saiyan, and Gohan is a saiyan, you can tell by the tail" you say.
"Me and my son are humans, but i never could explain the tail," Goku says. "Whatever you say," you concede, knowing how stubborn saiyans are, whether they believe they're saiyans or not.
You spend the next few months living and training at the KAME house, when a saiyan with rockstar hair and a scouter comes, takes Gohan, threatened Goku, and smashed Krillin into the wall, and then tried to fly away.
