These are the stories of Son Goku. These aren't the story of young Kakarot being sent to Earth where he grows up to be Earth's greatest protector. These are the stories of Son Goku after Chance interfered with Fate's plan.
Fate always finds a way. Even if Kakarot died on Vegeta, there would always be a protector of Earth and seeker of Dragonballs named Son Goku. No matter who filled the role, or how wildly different their life was, Son Goku would save the world from all who would threaten it.
These are the stories of those who filled the role after the demise of Kakarot.
Beyond this page is the first part of their tales, the day they were given and accepted the name of the protector of Earth.
