OmniSpectra
when I read this, at first I was LIKE NA COOLER IS OUT OF CHARACTER then I sat down and thought about Cooler's character and stuff and did research and I have to say you nailed Cooler too bad he never got stronger I do hope eventually he unlock a new form instead of being golden Cooler he can be Silver or Platinum ya know.
love it, specially how you expore more about the universe, i mean they destroyed planets and sell them, imagine how vast and interesting is the alien Society as a whole, glad you explored that and make mc have some planets under his wing, my only oncenr would be mr satan, dont get me wrong he is a good person and everything, but i wouldnt like him to steal mc's fame and glory while making him look weak like canon, it would be better if 1) MC make his alien and powerfull existance known to erth so they know who is their ruler, or 2) keep the people on earth on darkness, they wont know about freezer or buu and they certanly wont asume mr satan is stronger than he is, yet he will still be famous since no one knows about the real threats of the universe
