In the story bordok thinks freezer is going to find out about the legendary super sayain and is going to turn is back on the sayains and destroy them all.
But they did not show something;it is that bardok could see in to future events, he saw that freezer will distroy them so he told gine to send kakarot to be sent to earth . Gine as a mother said no, bardok said freezer is going to distroy as gine still does not agree with him so bardok says if it does not happen i will go and get him. So that how goku is on earth. But it was hard to get kakarot though freezers army so bardok fights the amy and is almost winning but freezer uses his energy blast that is surprisingly destructive it is called a death beam. Before bardok is destroyed he has a vision of kakarot fighting freezer and wins, am not doing to say the second one but the third one was about the tournament of power he see freezer and kakarot working together in a way he is happy and not happy 😀😡 at the same time and thats the story of bardok .
