this is a complete, but quick list of all my matchup opinions.
We all share different experiences as DK mains. Some of us are are more experienced than others in certain matchups. I think referencing our experience to credited players of those characters is useful.
Personally, i don't see DK having any true advantage on any high tier- and in fact losing to almost all of them, losing to some mids, going even with some mids....
know what logic what say about that? He's lower-mid. Yup, i just went there.
MK: 65 ('nado and reverse UpB edgeguarding) (i have Lee, Dojo, etc exp in this matchup)
Snake: 60 (people seriously underestimate the power of CAMPING in brawl) (exp= razor, lee, ice, etc)
DDD: 80+. No point in listing credentials for opinion here. IMHO 80 might as well be 100 because its not winnable against a pro DDD who won't **** up.
G&W: 50 (i blame B.air, otherwise DK's advantage)
Falco: 65 (laz0r, chains, phantasm runaway) (some matches w/ sethlon)
ROB: 60 (edge camping ftl, don't get behind for one second) (Sudai aka gayest rob ever)
Marth: 50 (RoyR, Dphat, ect. I can humbly say i probably know the DK vs Marth matchup better than anyone. Its been the vast majority of my brawl experience, and i'm certain its even.
Wario: 60. set w/ PhantomX. Assuming he at least averages 50 damage from the chainthrow and DK has grab release KOs from 80-120%. But if Wario doesn't mess up any chainthrows + farting DK's recovery = bleh
Lucario: 50 (i'm probably the authority on DK vs lucario. Lee Martin is obviously a better player than me, but i almost always bring him to his last stock w/ 50+%. Lucario can combo the CRAP outta DK, DK can KO lucario at 100% which takes away some of his Aura's effectiveness, both are very dangerous versus each other when off stage.
Diddy: 65 (i dont even feel like talking about diddy. i hate him, but its 'winnable', with good games around and using bananas yourself, i guess.
Pika: 55? (pika's my true 2ndary, but lack IRL pika exp, but previous disucssion makes obvious sense.
Ice: 60 Dk is comparatively an easy target to grab, DK can Kill Nana easily, but DK's lack of safe approaches really hurts him.
Kirby: 50? I lack enough good kirby exp.
Pit: 55? I've played Kawn, and Esca but i'm not confident i have enough experience yet-but its obvious to me Arrows are super gay vs DK, and Pit's attacks have enough longevity to get around most of DK's dodges plus knockback so DK can't punish.
wolf: 50..mayber 45 to DK's adv.
toon: 60 caaaaaaaaaaaaaaaaaaaamping >>>> DK (exp = Jerm, HyrulianRoyalty aka Hyro, and Lee)
olimar: 45? the only olimars i've played i've *****..but i can understand where people would disagree here.
fox: 40 lasers, uptilt combos and thats about it. DK makes up for it enough elsewhere.
zelda: 40. As long you don't rush her like an idio, DK should be able to control the pace.
zamus: 50. her B and forward B **** DK. she needs to run away to win, but DK can outlive her easily
bowser: 40
luigi: 40?
peach: 50 range and power vs safety and combos
ike: 40 i think still very winnable for ike
sheik: ??
lucas: 20 (or 40 w/out gay infinite to d.smash)
ness: 20
mario: 45 (bluejay, best mario in TX)
trainer: 40
samus: 40 (matches with xyro)
yoshi: 40 (matches with bwett and furbs)
sonic: 45 sonic is too fast and hit and run...
jigs: 35?
ganon: 35
link: 40
capt: 40
