You're a bit silly.
You're implying and stating that those match ups are '**** match ups'
WHEN the character has the 3rd best tournament representation (IIRC over total amount of tournaments since Ankoku started hes 3rd as well, 4th at worst) with 500 billion **** match ups, how about you do the math?
Similar logic was applied to Wario at one point.
Dedede isn't ***** by ANY of those characters, as I said it's stage dependant!
They have (oh the irony) gay cgs that rack up considerable damage. But guess what? Dedede is the ****ing heaviest character in the game with DI, and other than MK and Pikachu, all those characters are HUGE BEACONS OF **** for d3's gimping game.
D3 is one of the only characters in the game to actually outspace some of IC's broken crap (hallo blizzard). With the right stage Dedede becomes a troublesome match up for the ICs (his only issue is his size and speed allowing him to be more 'easily' grabbed).
Without a large enough stage for Falco to phantasm away for 7 minutes (Battlefield... Lylat...), Falco will not only have a hard time killing D3 (like he does on every stage), but can't indefinitely avoid the destruction d3 can force onto Falco through easy throws off the stage, ***** recovery, and invincibility frames on his utilt going straight through his silly phantasm, and on those smaller stages, d3 will always be an ftilt away; D3 PS'n all of Falco's lasers while D3 gets closer is going to win, eventually. It's just an exhaustive and over all gay match up.
Pika is unbelievably similar to Falco; I'm pretty sure I've heard Pika mains say it's no better than 60:40, maybe EVEN.
You're silly for mentioning Meta Knight. If MK can't get d3 off stage, MK struggles. Wasn't it M2K who said "Dedede vs MK is more even than you think"? I don't see Atomsk complaining as he always getting top 4 in one of the highest saturation of MK regions in the WORLD.
Lolimar gets gimped hard, and D3 has reliable down throw tech chases on him? What? D3 also outranges Olimar's moves? Only thing D3 doesn't outprio is purple pikmin with his jab, dtilt and bair? Oh, right, D3 gets *****. Disregard this then!
