Think DBZ. The Androids won in the main universe of DBZ. Future trunks went back and created a new timeline where the heroes win. The universe that, from our perspective, is the main universe, could just be an alternate universe that was edited. In all the universes trunks didn't edit, everything after majin but didn't happen because Androids. It also is the only universe where this is the case.
