Link VS Mario= Link
Reason: Out of all Marios bosses he has had to face, Bowser is the toughest, but I bet Bowser isnt even as tough as the first boss Link had to face. (Gohma) Link has been through a lot more, and has a larger arsenal of weapons, and in Sword VS Fist combat, who do you think is gonna win?

Bowser VS Donkey= Bowser
Reason: Bowser has an armor shell and spikes. He also has fire breath, he is also stronger, he also meaner, he is also bigger. I think this one is obvious.

Zelda VS Samus= Samus
Reason: Its basically Magic VS Technology here, along with the fact that Samus is agile enough to dodge any Magic attacks, and since she speciallizes in fighting, this one was the hardest choice but it still wasnt that hard.


BTW I got a question with some real debate potential:
Mario VS Luigi

I know everyone thinks that Mario is better because he has been in more games, but I dont think that necessarily means he would win in a fight with Luigi.
