Sonic has the edge in speed and he’s obtained many power ups over the years. He has the 7 Chaos Emeralds and he can also transform into Darkspine Sonic. I don’t want to underestimate Dio Brando, but he just won’t have enough skills to win this round. Sonic massively speed blitzes him for the win and Dio Brando just won’t have any defense against him. Sonic is just far too skilled to lose this round. Sonic wins.
