actually water gun lols at dk's recovery haha
i'm going to be honest, of all the characters, dk is the one i ENJOY battling the most, with all three. i really felt that all three pokemon were at least neutral.
but anyway, i highly agree with ivysaur, and charizard as well. although i would make a case for charizard to be x4 strong if he weren't so outranged. flamethrower is AMAZING against dk, it's almost like bullet seeding him. seriously. and dk has NO effective way of getting out. the closest thing would be to di towards you and dair or something...but even if you get daired, you'll take like...15-20% tops maybe? and he will have taken at least 30% if you really got a good flamethrower on him. flamethrower on dk is like flamethrower on falco, you rack up damage like crazy. especially if you use it to edgeguard. ;D i think flamethrower cancels out his spinning kong, but i'm not sure. also, your grab outranges his, so if you have the spacing necessary, feel free to shieldgrab his tilts and go to town. dk is one of the easiest characters in the game to "string" attacks against.
AS such, if you do get a squirtle grab or something in on dk, you can and usually will string a nice series of attacks on him. if he airdodges your fair or something, that's no problem because squirtle's attacks are so **** fast that you can just bair right after and keep going!
iduno, i mean dk's ftilt is "slow" enough that if you jump in and he tries to swat you with it, you can dodge it and jab him and follow him into the air.
but egale makes a valid point about shieldgrabbing, which i don't believe any of the dks i've faced have really abused against me. but for that reason, i think a defensive squirtle, playing slightly outside dk's (huge) range and waiting for an opportunity to strike could be effective. as you are outside that range, you can also mix in some shellshifting and hydrograbs to get things going and keep dk on his toes.
really, i think squirtle should try to bait and avoid an attack on dk's part to take advantage of the opening unless it's the uber quick dtilt, which, if he is spamming, lets you quickly go to the air and hit him in the face. i'm pretty sure dtilt's hitbox only extends to his hand and arm. and yeah, some dk's will dtilt maybe 3 times in a row because they know it totally shuts down any ground game squirtle has. but you have to be CLOSE to take advantage of this, which is why you should play a smart mid ranged game, poking at him and shellshifting around so you stay relatively safe.
i think squirtle is at a slight disadvantage at worst here, all things considered. maybe even like 45-55 neutral? if you do land an attack on him, there's always a strong possibility that you can follow up with at least 2 or 3 more. it's so insanely easy stringing attacks against him...
EDIT
also, yeah i think zard/should be neutral AT BEST and squirtle/meta down to slight disadvantage. check the last post in the old thread for why i think so
PERHAPS we should make the next discussion on DK?
