Dio Brando is very powerful and he can fight at high speeds. His mastery over time helps make this illusion even stronger and there aren’t many fighters who can stand up to him. Of course, Vegeta happens to be one of those fighters and one Big Bang Attack would certainly bring an end to this match. Dio Brando just doesn’t have the physical abilities needed to keep up with a Super Saiyan like Vegeta. The match is as good as over before it has truly begun. Vegeta wins.
