Nice idea, but I have something different in mind: Satan has always had a burning hatred for Mario.exe since he escaped Hell years prior to the arc. So, during the final battle of 'SMG4: Mariopocalyse.exe', Mario summons Satan, who then grabs Mario.exe and drags him down to Hell for eternal punishment, therefore stopping the apocalypse and saving the kingdom. However, much like your idea, this is the only time Mario.exe shows fear.
