Here's the new plot. New bad guy shows up and he's stronger than everyone. Even though he can kill all the Z fighters , he still gives them time to train and prepare, so the Z fighters train profusely , and eventually they fight and they fail, all while waiting for Goku to show up because he's either dead, sick, or still training...but definitely not too busy being a good husband and father. Finally, Goku shows up!
Goku and the villain stare at each other for 20 minutes while floating in the air. Then, there's endless amount of irrelevant dialogue in between punches, kicks, and energy attacks, which leaves the villain surprised that Goku is so strong, even though he gave him time to train and prepare. Goku puts up a good fight and he eventually transforms into a SSJ 20, but unfortunately he's still not strong enough, so he needs help from all his friends, including Vegeta, who is angry at the new writers. In the end, they defeat the villain and Goku takes ALL the credit as the sole savior of earth. The end.
