I don't know who wrote this or if it's based on some official manga, but I stopped watching when they got to the "Multiverse Tournament" part. It's a boring and lame idea for a plot. I mean, I know it's DBZ and tournaments are popular in the series. But the "Let's gather fighters from different dimensions and pit the against each other" is a little too unoriginal for my tastes. That and the whole "I'll destroy the mulitverse by killing the original universe." I hope they don't go in that direction.
