True Fusion Begins (A DBZ fan fiction)

7 years after Dragonball Z ended, So Pan is 11 and Bulla is 13, everyone capable of fusion with one another has figured out how to normal or Potara. Although the basic rules still apply for instance, with normal fusion you have to be the same size and must have your power levels the same but it can be held for longer or shorter than 30 minutes. And with Potora you don't have to hold it forever. (P.s. My story starts 7 months after kid buu was defeated but works its way to 7 years after it ended.)
