We're fifty parts into this story already. Amazing, no?
Remember folks, no matter what, Kirby > Meta Knight.
Meta Knight > King Dedede
Kirby > Meta Knight > Keeby > King Dedede
Meta Knight > Kirby = Keeby < King Dedede
In SSBB, anyway.
'Course, in SSB4, that won't be true since they'll nerf MK into oblivion...
@Meta-Mind: Okay, seriously, why is Meta Knight in the number 1 spot on the tier list? HE'S NOT THAT POWERFUL. Most of his moves just allow you to cheaply and quickly damage your opponents, allowing people to win against any opponent with no real skill and...
Oh, never mind. I just answered my own question.
He's quick and has ULTRA-powerful KO moves (Fsmash, Shuttle Loop, and Dsmash), plus the infamous Spammy Weather Attack. Add that to his EPIC (some even say broken) recovery... Well, you see the result.
Okay, then. It's just that the moves you mention never seemed particularly powerful to me... Yeah, they CAN KO pretty easily, but your opponent needs significant damage already... Plus, his Final Smash is kind of lame.
Kirby > Everybody
