Mario is the referee of every fight. He starts the fight, he counts up to 10 when Mac or his opponent kisses the mat and he declares KO! and TKO.
After Round 3 Mario decides who the winner is. But according to the manual Little Mac has to fear Mario`s unfair home side decisions.
 

Rumor:
It seems that Mario is marries and has at least one child.
In Mike Tyson`s Punch-Out!! Mario only acts as guest appearance. But Mario is the real hero of Nintendo. Games like Super Mario Bros. are milestones of video game history!!!!
