One Punch Man VS Sargeras
One Punch man. Since he's a shtick character he would only appear in fiction in which he could easily win. More likely though is a draw with Sargeras destroying OP's planet while he was out getting groceries and OP is just stuck floating in space forever.
A couple of old paladins with reckoning bomb.
One Punch Man is so strong that his hair fell out. Sargeras still has hair (fire hair is still hair).
Therefore One Punch Man beats Sargeras in a fight.
It depends what mood Chuck Norris is in at the time.
Probably running on a Pentium 4
I sincerely hate the newfg Saitama fanboys beyond what words can describe.
Probably Gandalf
Saitama. His power is always so strong that he kills in one punch
