In an attempt to help us better understand Dedede as well as the game as a whole (in the form of complete MU charts for every character), I'd like to make a new matchup thread where people can speculate and attempt to form a legitimate MU chart for every opponent. The other thread is like, old and not really the same.
So, post what you think all (or some, if you only feel confident in some) matchup numbers are and I will collect this data and keep this post updated.
I've reconsidered my previous 10's only strategy; this game is too balanced for sticking to just multiples of 10. Since there probably aren't matchups worse than 70 - 30, and there's no need for numbers outside that extreme, using multiples of 5 gives more granularity in the smaller overall space we have. Or something.
tl;dr 70 - 30, 65 - 35, 60 - 40, 55 - 45, 50 - 50, and so on in the other direction. Put Dedede's number first and the opponent's number second.
Here is a matchup chart mockup that we can fill in:
I'll be using the standard Wiki matchup icons:
I think I'll also use my Wiki user page to host the matchup chart table, instead of me having to always edit that image up there.

My thoughts. Mario has a good neutral game / approach with fast fireballs and has good combos on DDD with up-tilts and up-airs, etc. He also has a pretty solid recovery, especially on stages with walls. I'd say Mario is ahead in the matchup, but maybe not by much. Truthfully I haven't seen this matchup play out all that much. This is just theory crafting.
I think it's probably 60 - 40 for Mario.
- - -I can agree with Mario being tough. 40-60.
Luigi
- - -I'm inclined to say we beat Luigi, but I don't have enough experience in the match-up to say how much
Peach
- - -I feel confident about the Peach MU, I'd put it near 55-45. Debatably 60-40
Bowser

Yoshi

Wario

Donkey Kong
- - -Donkey Kong also feels good for Dedede.
Diddy

Link
DDD loses hard to link (not 30-70, but definitely around 40-60) and although i've never played a competent toon link main, it seems as though that matchup wouldn't be much better
- - -DDD link is even
Toon Link
Tink is difficult but not unwinnable. 40-60
- - -DDD loses hard to link (not 30-70, but definitely around 40-60) and although i've never played a competent toon link main, it seems as though that matchup wouldn't be much better
Zelda
- - -ALSO, as Zelda I don't mind facing DDD. his offstage game still works on her, but smart teleports can get her to the edge before DDD can land fair. On stage dins can create some obstacles for him because I'm not sure how many fast moves he has to eat them that can't be baited to land kicks. Lastly she can land kicks easier on bigger targets. She still dies super early however, and DDD has solid punish and some range to hit through Nayrus. I would say it could go either way, will try to think more about it next time I play it.
Sheik
- - -We win vs Sheik, but I'm not sure by how much. This is a MU I've talked with Fly about and he likes it too. I'd chalk it up to 60-40 for now.
Ganondorf
- - -Ganondorf appears to have a lot of trouble with D3. 65-35
Samus
- - -We are well equipped to deal with Samus. 60-40
Zero Suit Samus
- - -ZSS is bad news
Kirby
- - -Kirby is a challenge, but I'm not sure its all that good or bad for us.
Meta Knight
- - -MK 55-45 our favor.
Fox
- - -
Falco
- - -
Wolf
- - -
Pikachu
- - -Pikachu feels uphill, but not too steep. 45-55 to 40-60
Jigglypuff
- - -
Mewtwo
- - -Mewtwo doesnt seem far from even, but I don't really feel afraid of the MU.
Squirtle

Ivysaur
One of Dedede's most apparent character weaknesses is his unimpressive neutral game. Because of this, the tools that Ivy has here are much more useful. Keeping Dedede out is fairly easy, and this should be put on blast in the match-up. At best, your opponent should have to sift through an unreasonable ocean of defenses. Forehead height razor leafs will gain you a lot of mileage alone. A Dedede will quickly learn to fear vine whip and Ivy players should be keen to learn how this move can be used to restrict their opponent's gameplay. For example, on stages like Battlefield and Dreamland 64, D3 players have a powerful urge to jump from the ledge due to the fact that any aerial they preform will be auto ledge-cancelled. You should be able to snag a few vine whips from this habit. King Dedede also has the gift of arguably the deadliest off-stage game in Project M, so you should be careful, unpredictable, and very safe when making your way back on stage. Be wary of using your dair recklessly, as it is a great move for Dededes to try and strike you out of.
- - -Ivysaur is only winnable with a lot of experience. 35-65
Charizard
- - -
Lucario
- - -Lucario always struck me as annoying. 40-60
Captain Falcon
- - -Falcon is one of the characters I prefer going Dedede for, rather than (my main) Ivy. 55-45 to 60-40
Ness
- - -Ness feels 50-50, as does Marth.
Lucas
- - -Theoretically, Lucas should be crazy hard because of all the momentum he can get going, but all the Lucas' I've faced make it seem about 45-55. Idk though, I don't have too much experience in the MU.
Ice Climbers
- - -
Marth
- - -Ness feels 50-50, as does Marth.
Roy
- - -
Ike
- - -I'm confident we have adv over Ike. 60-40
Mr. Game & Watch
- - -GnW vs DDD is really difficult from my end. Even with bacon being a pretty good wall, there is no safe recovery to get around DDD's fair.
Pit
- - -
Olimar
- - -
ROB
- - -
Sonic
- - -We lose to Sonic.
