If they were to only use they`re physical strength: Knuckles, because first of all Knuckles possess alot of power, and Mario can`t crush a guy with super strength...but with weapons...idk...because of course Mario will become star, and for Knuckles...he has the MASTER emerald...which has more power then the chaos emeralds...and can control them...and doesn`t Star Mario run out of power? The Master Emerald doesn't run out.
I like both but Knux will probably pummel Mario.
In my opinion, Mario would win easily. In my opinion, yes. Sonic would win.
No weapons: Knuckles attempts to pummel Mario, who uses his jumping skills to dodge and land on Knuckles head. This would have little effect however, because Knuckles is very tough. Tie. Weapons: Mario uses a Star to go invincible, Knuckles uses the Chaos Emeralds to go super. Tie. Mario because he doesn't look like a platypus. KNUCKLES IS AN ECHIDNA WHICH LOOKS NOTHING LIKE A PLATYPUS!!! KNUX HAS NATURAL ABILITY AND MARIO NEEDS POWER-UPS.
Megaman would most likely win if he was in a fight with Knuckles the echidna.
Sonic
No
if your talking about knuckles the echidna then i would say knuckles :) Can you use logic? The Hulk is 50 times the size of a stupid red animal. All the Hulk has to do is to use his Hulk Smash!
Mario
Mario, in my opinion.A:Espio would win easily because: 1. he runs faster than Mario2. espio is a ninga and ningas kick ass3. espio would turn invinsible then Mario would be doomed4. espio can beat Mario anyday
Mario for sure!
Mario
Mario
