Author's Notes:
Right, here's the timeline that I've been meaning to make for a while. Most of the events stated above are taken from the DBO, Xenoverse, and GT, as well as making my own little adjustments to fit what I have in store for this story. Suggestions are also welcome. I also be updating this part from time to time.
Bloom Leigh is my OC creation and Vegeta's little sister who'll be appearing briefly in Chapter 4. She looks like Bulma but her hair spiky in a way that resembles a mix between Bulma and Videl's hairstyles from the Cell Saga and Majin Buu saga respectively.
In case if any of you didn't know, Beat and Note are from the arcade game Dragon Ball Heroes. They're the default male and female Saiyan heroes from the trailers and its spin-off manga. Decided to include them because "Why not?"
