I'm here playing as Sonic and I defeated this guy twice already with two stocks remaining. I died at f*cking 12% here only because I choose to be fast/light-weighted and close ranged? Nobody dies at 12%, ever. Little Mac is the most unstable character in a Smash game ever and I don't know what Sakurai took into his body but it wasn't something from the Fountain of Youth this time. Everybody with a little bit of common sense would remove this character from his game immediately. I'll stop waisting my time with people playing as Little Mac. Just jump off the stage and find somebody else before I kill everybody in my path due to rage. 

He used his KO punch...

Ive died at 0% several times. Lost track of my character and ran off the stage

I agree that Little Mac is annoying to fight but the KO punch is not much of a problem since it has a timer. I usually go into bait/run away mode whenever the KO punch is active.

Just grab Mac and throw him on the air. He's literally useless on the air.

Neh, hes not that hard to kill... It shows u when his power meter is up so just be more careful when it reaches KO point

Well... you also kind of ran directly into a fully charged fsmash. So, no johns.

Or you could have just not gotten hit by the KO punch. You didn't seem to have any trouble dodging all of his other attacks.

Anyway, match-ups are what they are. "Counter-picks" are a real thing. Next time someone picks Little Mac, try Mega Man.

Well, it depends, you might get a Little Mac like this which is usually what happens in my case

EDIT: No, this isn't my video

I don't blame myself for being close to him since Sonic IS a close range character. Do I have to run away for several minutes only because of his overpowered smash? Where's the fun in that. Dying at 12% is ridiculous especially for characters who always have to be close to their opponent. The KO hit shouldn't be there in the first place besides his cheap-ass super armor. Besides that, you can clearly see who's the better player here. I only lost because he's playing as Little Mac
