Mario vs Luigi

It should come as no surprise to me that you have taken such a simplistic and wrongheaded approach to determining a victor in this particular brawl.   To help demonstrate the asininity of your conclusion, I find it helpful to think of Mario and King Koopa as the Dons of rival mafias.  Luigi, in this scenario, is the covetous underboss, jealous of the power his shorter, redder kin wields.  From the outside, this undercurrent of envy is clear to all, but Mario is oblivious – his eyes, and worries, remain firmly fixed on his terripanic rival, never suspecting that Luigi is plotting a move to usurp him as head of the Mario syndicate. 
The brawl itself would end swiftly.  Luigi unexpectedly knocks his brother to the ground with a blow from behind.  Savagely, he pummels Mario’s limp, lifeless body, until his green shirt and hat are as red from blood as his dead brother’s.  And, like that, Mario goes to sleep with the Cheep Cheeps.
