The "Tree Of Might" story has a very different ending...

In a twist of fate, Bardock is transported into the future to the day his sons had their fateful encounter. Given a second chance at life, the psychic Saiyan warrior is faced with a moral dilemma: can he become the father for Kakarot that he never was and help the Earth's Special Forces battle deadly incoming threats to the universe, or is he too far gone to do any real good?

You live your life thinking you know everything that goes on around you. The old perverted man's one-track mind only thinks of groping innocent young women. The chef who can live all alone thinks she's the best choice for a wife. A curse can't be all that hard to live with if it's lasted for nearly two years. Oh, how the universe just loves to prove dear Akane wrong.
