Well, this is the closest fight that we will ever get to see a fight between this two I guess before Saitama gets a potential power creep in One-Punch Man, but anyways let us see how this fight goes. Saitama is around star level according to Secret One-Punch Man Notes Compus stating that Boros's Collapsing Star Roaring Roaring Cannon can obliterate the star with Saitama canceling out the attack like it was nothing, and obviously we don't want Saitama fighting against Frieza tier opponents who can destroy Namek that span an explosion that reached several light years in the anime. Therefore, Slug tier opponents will be the challenger for Saitama in this fight!
