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, 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
Mario for sure!
Mario
Mario
An orca would win the battle!
