Dragon Ball: The Degenerate Known as Kakarot

The soul of a modern man is unceremoniously dumped into the body of a 3 year old Kakarot, who just woke up in his space pod after crashlanding on earth. As he gains awareness of his situation, he ponders upon the threats he must face. Frieza. Cell. Buu. Beerus. In order to prepare for these threats, he must train. Train harder than he ever has before. He must break his limits, time and time again. Push himself to the max, just to survive... But those threats are years away! For now, let's just have fun.
