King Dedede (デデデ, Dedede) is a playable character in Super Smash Bros. Ultimate. He was confirmed as playable along with Rosalina & Luma and the rest of veterans on June 12th, 2018. King Dedede is classified as fighter #39.

King Dedede’s voice clips from Super Smash Bros. 4, where he was voiced by series creator Masahiro Sakurai, have been repurposed for in Ultimate.

How to unlock

Complete one of the following:

• Play VS. matches, with King Dedede being the 30th character to be unlocked.
• Clear Classic Mode with Donkey Kong or any character in his unlock tree, being the 4th character unlocked after Rosalina & Luma.
• Have King Dedede join the player's party in World of Light.

With the exception of the third method, King Dedede must then be defeated on Fountain of Dreams.

Attributes

King Dedede is tied for the third heaviest character in the game with Donkey Kong, making him a super heavyweight. King Dedede shares some typical attributes with other heavyweights, such as a high damage output, high KO potential, great endurance, quick falling and third fastest fast falling speeds (both tied for second and third fastest respectively), overall sluggish mobility, and a high susceptibility to combos. In addition to having an average initial dash and the thirtieth highest gravity, King Dedede has the twenty-eighth slowest walking speed, eleventh slowest dashing speed, the worst air speed in the game, and the fourth slowest air acceleration. To counteract these flaws, however, King Dedede is gifted with four midair jumps.

As a super-heavyweight, King Dedede has immense endurance, both vertically and horizontally. His massive weight makes him difficult to launch, and his incredibly fast falling speed lets him return to the ground quickly. Despite having the worst air mobility, his four midair jumps and Super Dedede Jump, the latter of which travels a very long vertical distance and has super armor during its ascent and descent, gives him great recovery for a heavyweight. Super Dedede Jump also has a meteor smash hitbox during its descent, making it risky to intercept if he recovers high. His tech rolls are unusually long-distanced for a character of his size, making him difficult to tech-chase. Finally, King Dedede's trademark hammer grants him a long disjoint in many of his attacks, allowing him to safely space his opponents.

True to a heavyweight character, King Dedede is gifted with an abundance of KO options and finishers. King Dedede's dash attack is a notable example, dealing huge damage, high pressure to shields, and being able to KO at a mere 55% on middleweight opponents. King Dedede's smash attacks all possess good damage and knockback, while having their own perks: forward smash can KO at 30%, has deceptively short ending lag, allowing King Dedede to quickly react, while also being able to deal immense pressure to shields with only a slight charge; up smash KOs at 100% and sports transcendent priority, while coming with good range and speed, easily being able to hit even the smallest of opponents, while dealing great vertical knockback; lastly, down smash is the fastest smash attack in Dedede's arsenal, KOing at 80%, having transcendent priority, and easily punishing rolling opponents.

The rest of King Dedede's grounded moveset comes with merits: neutral attack can deal multiple hits, being able to combo into itself, while the finisher's unique vertical knockback allows this move to KO at 150% under rage. King Dedede's forward tilt sports good range and startup lag, while its multiple hits are effective for dealing damage and starting combos, while also trapping rolling or floor-bound opponents; up tilt has quick startup lag and good range, allowing it to combo into itself while dealing good damage and leaving King Dedede's body and head intangible; lastly, down tilt deals good damage and has good range, being able to pursue opponents or retreat from them.

King Dedede's aerial game is also decent, thanks to his multiple midair jumps which allow him to stall and bait reactions from opponents. Neutral air is his fastest aerial due to coming out on frame 7, which can help disrupt enemy combos, and its late hit can also set up combos for Dedede himself, such as up tilt or up air. Forward air has a lot of range in front of Dedede, which is good for spacing with its decent startup speed, and can wall of pain at lower percents. Back air is a potent kill option with a good range behind Dedede, which is also a good option for spacing and landing. Up air can beat out a lot of down aerials thanks to its long-range, and it also has strong KO potential. Down air, when sweetspotted, is a powerful meteor smash offstage, but its use in general is limited due to its slow startup and small awkward hitbox.

King Dedede's grab game is less overwhelming than his grounded and aerial attacks, but it is still sufficient. King Dedede's grab only has average range, but this problem can be mitigated by simply dash grabbing. King Dedede's pummel is good for racking up on damage, due to its quick speed, which is especially deadly at high percentages; forward throw has good edgeguarding potential, due to sending opponents forward, easily being able to follow up with Gordo Toss; back throw is Dedede's strongest throw, dealing the most damage and knockback while having limited degrees of damage racking and edgeguarding potential; up throw can also be used to launch opponents into previously thrown Gordos, and can follow up with an up aerial; lastly, down throw's low damage and knockback lend it great combo potential, easily stringing into itself, and initiating combos with Dedede's neutral, forward, and back aerials.

King Dedede's special moves have decent utility as well. Inhale acts as a strong command grab that can be B-Reversed for landing options against shielding opponents on the ground or on platforms above Dedede. The spit can force opponents into a recovery state by sending them offstage or even spit them under the stage, which is perhaps where Dedede is strongest. Inhale also doubles as a reflector, allowing him to contest against projectile campers. The Gordos from Gordo Throw act as powerful stage control options with KO potential in their own right at 140% and above and can set up deadly ledge traps. Lastly, Jet Hammer is an effective punishing tool with heavy armor that does very high damage and knockback, and with a max charge, it can break full shields.

In spite of these strengths, King Dedede still has noteworthy drawbacks. King Dedede's biggest problem is his approach, which is among the worst in the game. His mobility is sluggish, especially in the air, giving King Dedede immense difficulty catching up to or retreating from his opponents. King Dedede's below-average dashing speed also makes him over-reliant on fox-trotting to cover grounded distances, which itself is somewhat predictable.

Although King Dedede's high weight and falling speeds allow him to easily return to the ground, they also render him vulnerable to combos, juggling, and chain throws while hindering his recovery. King Dedede's recovery is further hampered by his low airspeed and jump height, often forcing him to use his Super Dedede Jump to return onstage. Super Dedede Jump itself, in spite of traveling high, also causes King Dedede to descend very quickly; this, coupled with its limited horizontal maneuverability, renders Super Dedede Jump unreliable for recovering at certain distances offstage.

King Dedede's other specials can work against him, as well. Inhale has high ending lag, allowing other characters to easily punish him. Gordo Toss' Gordos can be reflected back at King Dedede from any attack that does 2% or higher, dealing immense damage to him and potentially resulting in a self-induced KO, requiring him to exercise caution or utilize Inhale on his reflected Gordos. Jet Hammer also takes a long time to charge, leaving King Dedede susceptible to attack, and its high ending lag leaves him vulnerable to punishment from his opponents.

Overall, King Dedede's high weight, endurance, range, and power allow him to punish his opponents with relative ease from distances, but his poor overall mobility makes King Dedede's approach somewhat abysmal and renders his recovery somewhat predictable and overly reliant on Super Dedede Jump. Dedede players should be careful to not make a mistake, else his high weight would render him to heavy punishment.

Changes from Super Smash Bros. 4

King Dedede was infamous for being one of the worst characters in SSB4, owing to a large number of considerable nerfs he received both at SSB4's launch and via game updates while not receiving a single buff in return, and his large amount of weaknesses, including notoriously poor frame data, his moveset's lack of power despite being a super heavyweight, and his special moveset's lack of utility outside of Gordo Throw. Possibly as a result of his poorly regarded status, King Dedede has been buffed overall in the transition from SSB4 to Ultimate.

Among King Dedede's biggest buffs are those to his ground game. Neutral attack's KO power was significantly improved, and it has undergone adjustments that make it harder for opponents to fall from the move as easily. Forward tilt connects much better overall, allowing it to deal its maximum damage more frequently, whereas up tilt has increased KO power (now having power comparable to its Brawl incarnation, especially with rage) and down tilt's angle was positively adjusted while its hitbox was fixed, which when combined with the changes to jostling allows it to connect much more frequently. Dash attack now deals significantly increased knockback and has had its hitbox fixed, now making it a usable (albeit still rather slow) punish option. His smash attacks are also more useful, with both forward and up smash dealing more damage and knockback, and his forward smash is now slightly faster.

King Dedede's aerial game has been improved overall as well. The universal reductions to landing lag improve King Dedede's limited combo and set-up ability, making his neutral aerial a more potent combo starter, and giving his up aerial's looping hits the capacity of starting drag-down followups. Particularly, his up aerial now deals significantly increased knockback, turning it once again into a reliable KOing option despite its angle rendering it more vulnerable to LSI. Forward aerial has also increased knockback, improving its ability to edgeguard. His grab game has been slightly buffed as well, thanks to his grabs lasting for one more frame and his standing and dash grabs reaching further, in spite of all his grabs receiving slightly increased startup and increased ending lag.

King Dedede's special moveset has also received several miscellaneous buffs, giving him options that either he previously lacked or were outclassed. Inhale has a much larger grabbox and has gained the ability to spit out inhaled projectiles with a one-time increase to their damage, effectively giving him a reflector, which helps alleviate his vulnerability to projectile camping. Gordo Throw's hitboxes are larger and more accurate and the move has less ending lag after a Gordo has been thrown. Additionally, Inhale's new ability to suck in projectiles to spit them out combines well with Gordo Throw, giving King Dedede another way to throw or re-launch Gordos at a faster speed, which gives the projectile much more utility. Lastly, Jet Hammer now deals more damage and knockback, has shield breaking potential, and it now has heavy armor before the move comes out that resists up to 14%, improving the move as a hard punish option.

Aside from direct changes, King Dedede also benefits from a few changes to universal gameplay mechanics. The universal increase to mobility has buffed his abysmal horizontal mobility (although it still remains among the worst across the series), while the streamlined jumpsquats and the new limitations to air dodge mechanics have increased the effectiveness of his aerial moveset, by giving him additional landing options when combined with the reduction on landing lag, and improving his edgeguarding ability, now making the latter more formidable. The changes to air dodging also don't affect him as much as other characters, thanks to him still boasting multiple jumps and a long-distanced recovery move.

However, King Dedede is not without a few nerfs. His back aerial, despite having a visually more accurate animation, has smaller hitboxes, slightly decreasing its range. His neutral attack and up tilt deal less damage, making the former a less reliable option for racking up excess damage. He has also received some nerfs in game updates, such as his forward smash not breaking shields at once. Despite this, most of his nerfs have all been minor in comparison to his more useful buffs.

Altogether, King Dedede's entire kit has been noticeably improved from SSB4, and while this doesn't change his core playstyle significantly (aside from Inhale becoming a reflector), it allows him to play to his strengths better thanks his moves gaining improved consistency and utility, allowing King Dedede to utilize his strengths better. However, it is important to note that, due to this, King Dedede still retains most of his core weaknesses from the previous game, such as slow movement speed, a lackluster disadvantage state, a vulnerability to some forms of camping, and a high susceptibility to rushdown and combos. Although King Dedede was initially considered among the best super heavyweights in the game, and remains a decent choice across all levels of play, his representation remains lackluster at top level, despite efforts from players such as ZAKI, Atomsk, and Peli achieving solid results in nationals and regionals. His vulnerabilities are also compounded by most top-tier and high-tier characters, such as Mario, Palutena, and Pikachu, among others. As a result, players have debated on whether King Dedede is as effective as originally imagined, with the current general consensus being that he stands at the lower end of mid-tier or the higher end of low-tier, since his improvements from SSB4 haven't fully addressed his weaknesses. In the end, King Dedede's true viability remains questionable.

Aesthetics

• Due to the aesthetic used in Ultimate, King Dedede's model features an altered color scheme. His clothing and general design are more cartoonish, with higher contrast colors and greater detail in his clothes; the fur on his coat and hat appears fluffier and more detailed, and his sash has more depth.
  • Normal map changes to the star textures on his hammer give the illusion that they protrude slightly more, as depicted in his official artwork.
• Like many other characters, King Dedede is more expressive. For instance, he now squints in a humorously seductive manner during his crouching animation. King Dedede generally has more furious expressions during attacks, his Screen KO, and his helpless animation.
• Down taunt now has a more exaggerated animation, with the belly-drumming animated to be more obvious.
• Two of King Dedede's victory poses were slightly altered:
  • His up-inputted victory pose now shows a Waddle Dee walking up to him. The ending animation is now more exaggerated, with Dedede bouncing while laughing gloatingly.
  • His right-inputted victory pose now finishes with him charging Jet Hammer.
• King Dedede's star KO voice clip has been shortened, as it no longer extends past the KO's animation.
• King Dedede's Boxing Ring alias has been changed to "Self-Made King", a direct translation of the Japanese title, for consistency with its appearance in Kirby Star Allies.

Attributes

• Like all characters, King Dedede's jumpsquat animation takes three frames to complete (down from 6).
• King Dedede runs faster (1.36 → 1.496).
  • Initial dash is much faster (1.4 → 1.815), enabling fox-trotting for boosted ground mobility.
• King Dedede walks faster (0.98 → 1.029).
• King Dedede's air speed is much faster (0.63 → 0.735), now being nearly on par with Luigi's.
• King Dedede's gravity is higher (0.08788 → 0.097).
  • His short hop and jump are shorter as a result (38 frames → 36 frames (short hop), 55 frames → 48 frames (jump).
• King Dedede is much heavier (119 → 127), allowing him to survive even longer.
• Forward roll has less ending lag (FAF 33 → 32).
• Forward roll grants less intangibility (frames 4-19 → 4-16).
• Back roll has more startup with less intangibility (frames 4-19 → 5-17) and more ending lag (FAF 33 → 37).
• Spot dodge intangibility starts sooner but also ends sooner (frames 4-19 → 3-18).
• Air dodge grants more intangibility (frames 4-29 → 4-32).
• Air dodge has much more ending lag (34 → 43).

Ground attacks

• Neutral attack:
  • The first hit has less ending lag (FAF 38 → 33).
  • The first two hits of neutral attack can now lock.
  • Neutral infinite has less startup lag (8 → 5), is faster, and connects more reliably.
  • Neutral infinite's finisher has less startup lag (6 → 4) and more knockback scaling (150 → 162).
  • Neutral infinite's finisher has 2 hitboxes rather than 1 (10u → 7u/7u), and the hitboxes extend farther vertically (Y offset: 10u-12u → 7.5u-13u (both)). The finisher has more range overall as a result.
  • The finisher has more ending lag (FAF 47 → 50).
  • Except for the finisher, each hit of neutral attack deals less damage (first hit: 4% → 2.5%, second hit: 4% → 2.2%, neutral infinite: 1% → 0.5%).
  • The infinite has gained a shieldstun multiplier of 5×. This allows it to lock opponents into their shields between each hit, and thus pressure them more effectively, but also allows them to cancel shieldstun and punish King Dedede more easily if they shield 10 hits or more.
• Dash attack:
  • Dash attack deals more knockback (40 base/100 scaling → 65/92 (clean), 35 base/100 scaling → 55/92 (late)), improving its already potent KO potential. This is boosted further by the changes to the Sakurai angle on the ground.
  • The clean hit and first late hitbox extend further inwards (Z offset: 7.8u-11.8u → 5u-11.8u), improving their ability to hit opponents at the edge, and combined with the changes to jostleing remove its blind spot.
  • Dash attack hitbox duration lasts longer with 2 new sourspot hitboxes (Frame 26-36 → 26-42).
• Forward tilt:
  • Forward tilt's looping hits have altered angles (25°/96° → 22°/100°) and have altered knockback (20 base/24/80/90 set/100 scaling → 60/50/30/26 set/100 scaling), allowing the move to connect more reliably.
  • Forward tilt has an altered animation.
• Up tilt:
  • Up tilt has less startup (9 → 7) and ending lag (FAF 44 → 39).
  • Up tilt does slightly less damage (12%/10% → 11.5%/9.5%).
  • Up tilt deals more knockback (50 base/80 scaling → 65/94), making the move much stronger despite the damage reduction.
  • Up tilt's hitboxes are smaller (7u/8u → 6u/6.5u), reducing its range.
• Down tilt:
  • Down tilt's clean hitbox now extends inwards (Z offset: 12u → 12u-6u), which combined with the changes to jostle mechanics removes its blind spot.
  • Down tilt launches at a lower angle (45˚ → 35˚).
• Forward smash:
  • Forward smash has less startup (42 → 40) and ending lag (FAF 82 → 78).
  • Forward smash deals more damage (15%/24%/6% → 16%/18.5%/25%/11%), and all but the shockwave and early hitboxes deal more knockback (30 base/93 scaling → 50/70 base/85/74 scaling).
  • There is now a hitbox on the handle during the early hit which instead of launching opponents pushes them into the sourspot of the main hit (which is still stronger than the early hit), making it slightly easier to land the main hit.
  • Forward smash has a new sourspot on the hammer's handle that's much weaker (though is still powerful in its own right), and the early hit deals less knockback (30 base/93 scaling → 85/55), hindering its KO potential despite its increased damage.
• Up smash:
  • Up smash deals more damage (14%/9% → 16%/10%) with no compensation on knockback, improving its KO ability.

Aerial attacks

• All aerials have less landing lag (15 frames → 9 (neutral), 30 → 18 (forward/down), 21 → 13 (back), 22 → 13 (up).
• Neutral aerial:
  • Neutral aerial possesses much greater combo potential due to its reduced landing lag and King Dedede's shorter jumpsquat, especially when hitting with the late hit.
  • Neutral aerial causes King Dedede's belly to wobble around during the move.
• Forward aerial:
  • Forward aerial has more knockback scaling (90 → 98).
  • Forward aerial has a snappier animation, with a significant delay on when King Dedede flips.
• Back aerial:
  • Back aerial is now a horizontal hammer swing, which better matches the move's hitboxes.
  • Back aerial now has 3 unextended hitboxes rather than 1 extended one (10u → 6.5u/6.5u/6.5u). Compared to the previous hitbox, the new hitboxes have both less vertical range (Y reach: 20u–0u → 16.5u–3.5u), and less horizontal range (Z reach: -25u–1u → 0.5u–-24.5u).
    • The hitboxes are now able to interpolate with King Dedede's movement.
  • Due to his reduced short hop duration, King Dedede can no longer jump out of a short hop back aerial before landing.
• Up aerial:
  • Up aerial's final hit deals more knockback (50 base/150 scaling → 55/167).
  • Up aerial launches at a lower angle (70°/80° → 60°), hindering its KO potential close to the upper blast zone, while also making it much more susceptible to DI and LSI.
• Down aerial:
  • The duration of the hitbox has been slightly increased (22-23 → 22-24).
  • It has an altered animation: King Dedede swings his hammer from his right instead of his left. It also has a more forceful animation.

Throws and other attacks

• Grabs:
  • All grabs have more startup (frame 7 (standing)/9 (dash)/10 (pivot) → 8/11/12) and ending lag (FAF 36 (standing)/45 (dash)/42 (pivot) → 40/48/43).
  • Standing grab's grabbox extends farther (Z2 offset: 11.5 → 12.5), improving its range.
  • Dash grab's grabbox extends slightly farther (Z2 offset: 14 → 14.4), slightly improving its range.
  • Pivot grab's grabbox does not extend as far outwards (Z2 offset: -19.5 → -19.3), which combined with the changes to jostling hinders its utility.
• Pummel
  • Pummel deals more hitlag (5 frames → 16), but has much less startup (frame 9 → 2) and ending lag (FAF 25 → 8), shortening its duration overall as well as making it harder to escape between each pummel.
  • Pummel deals less damage (3% → 1.6%).
• Up throw:
  • Up throw has improved combo potential due to King Dedede's faster jumpsquat and jump speed.
• Down throw:
  • Down throw has an altered animation, with King Dedede slamming his opponent face-first onto the ground.
  • Down throw now deals 8 frames of hitlag to King Dedede and the opponent before the throw occurs, rather than dealing 6 frames of hitlag to the opponent only. This makes down throw easier to DI and increases its ending lag, as its total duration was unchanged.

Special moves

• Inhale:
  • Inhale has less startup lag (frame 17 → 14).
  • Inhale acts as a reflector, giving a 1.5x damage boost to any projectiles spat out. Once Inhaled, the projectile is spat out almost immediately, and eliminates almost all of the move's ending lag.
    • Inhale can catch and spit Dedede's own Gordos. This gives him an option to relaunch Gordos that are hit back at him, and manually allows him to launch Gordos forward much further and at a much faster velocity compared to throwing one with Gordo Throw.
  • Inhale has a much larger grabbox.
  • Inhale's spit deals more damage (10% → 12%).
  • Spat out opponents deal more knockback to bystanders (70 base/70 scaling → 77/78).
  • Inhale has an updated, more opaque visual effect.
• Gordo Throw:
  • Gordos have significantly larger hitboxes on their bodies that don't shrink over time (3.1u/2.9u/2.6u/2.4u → 4u), and also have hitboxes that cover their spikes, considerably improving their area of attack, and doing a much better job at accurately representing the overall size and shape of the Gordos.
  • Gordos gain a surprised expression when deflected. Additionally, they have animated spines.
  • Gordos have a higher chance of sticking to walls (50% → 60%), improving their edgeguarding potential.
  • Gordo Throw has less ending lag (FAF 64 → 59).
• Super Dedede Jump:
  • Super Dedede Jump's landing hit deals more damage (11% → 12%).
    • It has altered knockback (80 (base)/100/80 (scaling) → 105/100 (base)/70/82 (scaling)).
  • Super Dedede Jump will snap to edge when reversed.
  • Super Dedede Jump descends more quickly.
  • King Dedede has blue trails form around him when using Super Dedede Jump, indicating armor.
• Jet Hammer:
  • Jet Hammer deals more damage (grounded: 11%-38% → 12%-40%, aerial: 10%-27% → 11%-32%).
    • Fully charged Jet Hammer deals more knockback (grounded: 5 (base)/66 (scaling) → 60/46, aerial: 10 (base)/70 (scaling) → 60/54).
  • Jet Hammer has heavy armor during the swing (frames 1-14) when used on the ground.
  • Uncharged and fully charged Jet Hammer's hammer head hitbox is larger (7.5u → 9u).
  • The fire from Jet Hammer is blue instead of red.
  • Fully charged Jet Hammer triggers Special Zoom upon hitting an opponent.
• Final Smash:
  • King Dedede has a new Final Smash called Dede-Rush, which features King Dedede taking his "Masked Dedede" persona from Kirby Super Star Ultra before trapping opponents inside of a caged boxing ring, attacking them with a barrage of missiles, and launching them with his Jet Hammer.
  • It deals more damage (46% → 59.6%) and knockback.
  • Unlike Dedede Burst in SSB4, it is not possible for opponents to escape once trapped.
  • Dede-Rush cannot trap more than one opponent at a time for extra damage.

Update history

King Dedede has garnered a mix of buffs and nerfs via game updates, but has been buffed slightly overall. The most notable nerfs were to Gordo Throw, as Gordos have smaller hitboxes and deal less shield damage, removing some shield break set-ups. Additionally, the Gordo-boosted Super Dedede Jump was removed altogether. Moreover, King Dedede's shield pressure was further toned down by removing forward smash's ability to hit grounded characters twice, which removed its ability to instantly break shields. It wasn't until update 8.0.0 where King Dedede had some of his kit improved. Up tilt gained a noticeable damage increase, down tilt's launching angle was lowered, and both forward aerial and especially up aerial gained increased knockback. Inhale was also made safer via reduced startup and larger grabboxes. Both up and down tilt now give King Dedede strong, reasonably fast KO options that he lacked, and Inhale is now better at catching approaches and projectiles. While King Dedede retains a lot of his fundamental flaws and hasn't been improved as much compared to other tepidly received characters, his buffs have given him more consistency despite his initial nerfs.

2.0.0

• Fixed King Dedede's knockback facial expression after Inhaling an opponent holding an explosive item.
• Gordos' hitboxes on their spikes (4.8u→3.8u) and body (4.5u→4u) have been reduced.

3.0.0

• Forward smash no longer hits grounded opponents twice. This significantly hinders its shield breaking potential.
• Fixed reflected Charge Shot from Samus that would launch the other way using Inhale.
• Opponents now properly gain intangibility when caught by Inhale; previously opponents would become stuck in hitstun during Inhale.
• Gordo Throw deals less shield damage.
• Gordo Boosted Super Dedede Jump was removed.
• Aerial Gordo Throw's animation has been adjusted.

3.1.0

• Scenarios where the opponent would not escape from Inhale after King Dedede gets hitstunned at a specific frame has been fixed.

4.0.0

• Fixed an issue where Inhaling certain projectile would become stuck at the center of the stage.
• Fixed an issue where Gordo would become stuck under King Dedede after catching it back during invulnerabily.

7.0.0

• Overall shield size has been increased by 1.15×.

8.0.0

• Up tilt deals more damage (10%/8% → 11.5%/9.5%) with no compensation on knockback, drastically improving its KO potential, to the point it is only slightly weaker than his up tilt in Brawl without rage.
• Down tilt launches at a lower angle (45° → 35°), allowing it to set up tech-chases more effectively at low percents and improving its KO potential at high percents.
• Forward smash has had its jostling properties adjusted.
• Forward aerial has more knockback scaling (90 → 98).
• Up aerial's last hit has much more knockback scaling (147 → 167), greatly improving its KO potential, being able to KO under 150% from ground level without DI.
• Inhale:
  • The move has less startup (frame 17 → 14).
  • The grounded version's grabboxes are larger (Z offset: 4u → 4u—7u (initial), 5u—9u → 5u—12u (vacuum), greatly improving its range.

Moveset

• King Dedede can perform 4 midair jumps.

For a gallery of King Dedede's hitboxes, see here.

Note: All numbers are listed as base damage, without the 1v1 multiplier.

		Name	Damage	Description
Neutral attack			2.5%	A pair of hammer swings, followed by thrusting his hammer forward while twirling its head, followed by an upward swing. Unlike most neutral infinites, its finisher launches opponents at a nearly vertical trajectory and has KO potential, as it KOs around 150% without rage. It is much faster than it was in SSB4, and connects more reliably.
			2.2%
			0.5% (loop), 3% (last)
Forward tilt			2% (hits 1-4), 3% (hit 5)	Thrusts his hammer forward while twirling its head. Very good range, though its fourth hitbox can only connect if the move lands at the tip of the hammer. However, its rather long ending lag makes this move unsafe if it does not connect at its farthest range. It is very useful for Dedede's ledge traps as its speed, range, and long-lasting hitbox allows it to trap rolls and neutral get-ups, but this is less rewarding than using his smash attacks. Also good for catching landings when reversed out of a run, and can stuff out punish attempts for a landed back aerial.
Up tilt			11.5% (head & neck), 9.5% (tip of head)	An upward headbutt. King Dedede's head and upper body are intangible while its hitbox is active. It has fast start-up lag with low ending lag. This move can combo into itself at low percents, and has KO potential at high percents. Its high knockback makes it the fourth strongest up tilt in the game, being able to KO Mario at 103% in Final Destination at 85% rage and no DI.
Down tilt		Rolling	10% (early), 6% (late)	A cartwheeling tackle. Dedede's fastest move, coming out on frame 6. It is capable of being used after most defensive options and attacks, as a good out of shield option, or for disrupting opponents. It can also lead to itself and other attacks if the opponent does not tech.
Dash attack		Belly Flop	16% (clean), 13% (late)	His signature belly-flopping tackle. A slow and powerful KOing option, it is the strongest dash attack in the game and is even stronger than some of the cast's smash attacks, KOing middleweights at around 55% near the edge due to its exceptionally high knockback. The attack can be used for a hard read or setting up tech-chases. Can hit every character on the ledge after their ledge invincibility has ended. However, its high ending lag causes the attack to be very punishable when missed. Originates from Kirby's Dream Land.
Forward smash			16% (head, early), 25% (head, late), 18.5% (handle), 11% (shockwave)	Rears his hammer back and slams it down. The most damaging and strongest forward smash in the game {and the third strongest forward smash overall, behind Lucario's at max aura and Hero with a critical hit). It can KO as early as 30% near the edge, even when uncharged, and when fully charged, it is even capable of OHKOing some lighter characters like Pichu near the edge of Final Destination. It has a very slow startup, but a deceptively short end lag and a long-ranged quakebox. It can break shields point blank with only a little bit of charging. Originates from Kirby's Dream Land.
Up smash			16% (hammer), 10% (body)	An upward hammer swing. A decent anti-air option with great vertical knockback, KOing at middleweights at 100%. Has good range in front and behind Dedede with consistent power throughout the duration, being able to hit short characters unlike in SSB4. It also has a transcendent priority.
Down smash			13%	A spinning hammer swing around himself. King Dedede's fastest kill move, sending foes at a low angle and can KO around 80% near the edge. Best used for catching rolls as well as ledge attacks. It also has a transcendent priority. Appears very similar to the Giant Dedede Swing from Kirby's Return to Dream Land.
Neutral aerial			12% (clean), 7% (late)	A splash. Dedede's fastest aerial, coming out on frame 7. Functions like a sex kick, but unlike the majority of them, it has transcendent priority, meaning that it cannot cancel out projectiles. When coupled with a fast fall, its late hit has follow-up potential, such as an up tilt at low percents, neutral, forward or back air at mid percents, and up air at higher percents.
Forward aerial			12%	Somersaults to perform a downward hammer swing. Has good range in front of Dedede, but can be unsafe on hit at lower percents if spaced poorly. This move does not autocancel in a short hop and has more landing and ending lag than his back aerial, but starts much earlier. Is capable of performing a pseudo wall of pain while edgeguarding. It can also lock and fend off edgeguard attempts while recovering, due to its long-range reaching through ledges.
Back aerial			16%	A horizontal hammer swing behind himself. One of Dedede's best moves for spacing and KOing, doing so reliably below 120%. Can be autocanceled in a short hop, and is also relatively safe on shield when spaced at max range.
Up aerial			1% (hits 1-7), 5% (hit 8)	Thrusts his hammer upward while twirling its head. It has tremendous reach above Dedede and can beat out numerous down aerials. It is quite strong for a multi-hit move, being able to KO below 130%. Like his forward aerial, it can hit edgeguarding opponents through ledges.
Down aerial			15% (middle of head), 8% (edge of head)	A downward hammer swing. The sweetspot is a very powerful aerial-only meteor smash. The meteor smash only activates at 28% or higher. On grounded opponents, it deals high horizontal knockback, KOing at around 100% near the edge. However, its usage is very limited due to its high startup, causing it to be Dedede's slowest aerial.
Grab			—	Reaches out. King Dedede's grab range is average.
Pummel			1.6%	A headbutt. Quicker but less damaging than it was in Smash 4. Good for racking damage.
Forward throw			4% (hit 1), 6% (throw)	Strikes the opponent forward with his hammer. It can be used to set up an edgeguard or launch the opponent into a previously thrown Gordo. King Dedede's second strongest throw. It can KO middleweights at around 160% at the edge of Final Destination.
Back throw			4% (hit 1), 9% (throw)	Strikes the opponent backward with his hammer. King Dedede's strongest throw, but due to the fact that it launches at a very high angle, it does not KO until very high percentages, it can KO middleweights at around 148% at the edge of Final Destination with no DI, but around 30% later with good DI. It is better at damage racking due to these factors. Like forward throw, it can be used to launch the opponent into a previously thrown Gordo.
Up throw			4% (hit 1), 5% (throw)	A jump set, a technique used in volleyball. It can lead to up aerial at low to medium percentages, but down throw is generally more rewarding and consistent. Like forward throw, can be used to launch the opponent into a previously thrown Gordo. It is King Dedede's weakest throw, as it only starts KOing middleweights at around 261% on Final Destination.
Down throw			6%	A one-handed body slam. King Dedede's best combo starter, it can initiate true combos into a neutral or forward aerial at very low percents and back air at low to mid percents. At medium percentages, down throw to up aerial is a KO combo if the opponent DIs incorrectly. It also has slight KO potential at very high percents, as it can KO middleweights at around 235% on Final Destination.
Forward roll Back roll Spot dodge Air dodge		—	—
Techs		—	—
Floor attack (front) Floor getups (front)			7%	Gets up and kicks in front of himself and then behind himself.
Floor attack (back) Floor getups (back)			7%
Floor attack (trip) Floor getups (trip)			5%	Swings his hammer in of himself and then behind himself while twirling the hammer's head.
Edge attack Edge getups			10%	Performs a kick while climbing up.
Neutral special		Inhale	12% (spit)	Inhales the opponent. While they have been Inhaled, King Dedede can then walk around and spit them out to inflict damage. He will also receive a 0.25x Received Knockback Multiplier, making it almost impossible to KO him while someone is inhaled. Inhale can also be used to swallow items and spit back projectiles, acting as a reflector. The reflector property is quite notable as unlike the rest of the cast, it has no reflect limit. Inhale is also a good landing mix-up to catch sidesteps and shields.
Side special		Gordo Throw	10% (hammer), 14%/12.5%/11%/9.5% (Gordo)	Hits a bouncing Gordo with his hammer. Its trajectory can be angled upward, forward, or downward, which can be used for mindgames. By extension, his throws can be used to launch the opponent toward a previously thrown Gordo. The Gordos disappear after almost 3 seconds. An upward-angled Gordo can be used to deny most options at the ledge or even all when combined with an attack. Gordo can also stick to any surface that allows wall jumping, and is much more consistent than it was in SSB4. They can also be reflected by any attack dealing at least 2%. Of further note is that Dedede can hit opponents with the hammer swing used to serve the Gordo, potentially leading into a hit by both the hammer and Gordo for a considerable amount of damage. Dedede can also inhale his own Gordo and spit it out at a considerable speed.
Up special		Super Dedede Jump	15% (drop), 12% (landing), 5% (stars)	His signature jump. It concludes with a diving double foot stomp that buries grounded opponents and meteor smashes aerial ones. Like Yoshi Bomb, it emits stars on both sides after the diving double foot stomp hits the ground, which can make it difficult to punish, especially against characters that lack a projectile. While it cannot grab edges during its descent, it can do so upon being canceled. However, if it is canceled too late before landing, Dedede will endure landing lag that lasts for more than a second.
Down special		Jet Hammer	12% (uncharged grounded), 11% (uncharged aerial), 40% (fully charged grounded), 32% (fully charged aerial)	Activates the afterburner in his hammer to charge up a very powerful swing, which is released when the special button is released. Dedede can walk around slowly and jump once while charging. It has heavy armor during the swing, and it can hit opponents hanging from the ledge after their invincibility wears off. The jet hammer will inflict the most amount of knockback if released just before the full charge. Dedede can hold the hammer out indefinitely, but it slowly does recoil damage if he holds it when fully charged up until 100%. A fully charged Jet Hammer can easily KO opponents below 50% near the edge, and is able to break shields with a full charge.
Final Smash		Dede-Rush	8% (hit 1), 1.8% (missiles), 20% (hammer hit), 10% (last hit)	Strikes the opponent with his hammer sending them into his trademark boxing ring with a cage set up. Adopting his Masked Dedede persona, he attacks his opponent with a barrage of missiles, followed by a powerful spinning hammer swing. Deals approximately 60% in total with considerable knockback, but can only trap one opponent at a time.

In competitive play

At the beginning of Ultimate's metagame, many professionals noticed Dedede's improvements from the previous installment, albeit still retaining some of his weaknesses there. This led to most of the community considering him as a low-mid or even low tier character. However, as professionals such as ZAKI and Atomsk began making notable impacts in major tournaments, most players' perception changed, citing his positive qualities such as his great edge trapping with Gordos, resilient endurance, disjointed range, and stronger KO power in comparison to SSB4. This led to Dedede becoming a popular choice among all levels of play in comparison to his release, most notably in local and regional tournaments, with the general perception casting him as an upper mid-tier or even high tier character.

However, updates removing Dedede's shield break combinations as well as shrinking the Gordos' hitboxes hurt Dedede's success: ZAKI's results failed to reach his prior success, Atomsk reduced him to a co-main, Big D rarely uses the character anymore, and Peli went through a short retirement followed by a several months-long character crisis and is currently co-maining the character with Palutena. Because of this, Dedede's representation has significantly dropped, with some players reconsidering him to be strictly a mid-tier character instead of a high tier character or, in some instances, a low tier character. In addition, Dedede's poor disadvantage state, inconsistent KO potential, and laggy frame data have caused him to struggle against most top tier and/or high tier characters, such as Palutena, Mega Man, and Fox. Although King Dedede is seen as a better character than he was in SSB4, his first definitive tier placement in Ultimate remains to be seen.

Role in World of Light

Finding King Dedede in World of Light

King Dedede was among the fighters that were summoned to fight against the army of Master Hands.

During the opening cutscene, King Dedede was present on the cliffside when Galeem unleashed its beams of light. He was vaporized offscreen and placed under Galeem's imprisonment along with the other fighters, excluding Kirby.

Dedede can only be accessed in a sub-area themed after the Gourmet Race minigame from Kirby Super Star, where the player must collect exactly 11 pieces of food for him to appear on the podium.

Trivia

• During the segment of the Nintendo E3 Direct that focused on King Dedede's Final Smash, his eyes are normal colored while he is wearing his mask. In the final game, his eyes are yellow.
• King Dedede is one of four characters that has appeared in all games with Final Smashes to have a different Final Smash in all of them; the other three are Pit, Zero Suit Samus, and R.O.B..
• King Dedede's pose in his official render resembles one of his idle poses.
• King Dedede's prank to the Kongs in King K. Rool's reveal trailer is considered an in-joke within the fandom, as it is perceived as his voice actor, series director Masahiro Sakurai, making a practical joke at the expense of the fans.
  • Ironically, both King Dedede and King K. Rool are opponents for each other's Classic Mode route.
• In the Korean version of the game, the Announcer calls him "King Dedede", despite having a slightly different name in Korean, "Dedede Daewang", which translates to "King Dedede the Great".
• In the Chinese version of the game, the Announcer calls him "King Dedede" in the Simplified version, while the Traditional version has the "Dedede!" announcement from the Japanese version.
• In the French and European Spanish versions, the name tag and voice clip from the announcer on the victory screen is slightly different from the one used on the character select screen, instead featuring a noticeable translation of "the" (le Roi Dadidou and el Rey Dedede, respectively). This trait is shared with Wii Fit Trainer, Pokémon Trainer, Villager, Ice Climbers, Inkling, Hero, and the Mii Fighters. Additionally, he and Duck Hunt are only two fighters having this trait in the European version, but not in the American version.
• King Dedede is one of the only two antagonists that can be unlocked in the Light Realm, the other being Bowser.
• Prior to 3.0.0, if King Dedede threw a Smart Bomb at his opponent and tried to Inhale them, the Inhale would not affect anyone until the bomb explosion was over. This glitch may likely have been caused by opponents stuck during the hitstun. When this happened, anyone caught in the Inhale from before will teleport into King Dedede's mouth once the explosion ended. Kirby could do this too. This was patched, where characters can now no longer be put into hitstun during Inhale.
• King Dedede is one of the five veterans from Smash 4 to have their Boxing Ring alias changed in Ultimate, the others being Link, Kirby, Mega Man, and Ryu.
• King Dedede appears in the most spirit battles in DLC Spirit Boards, appearing in the Yusuke Kitagawa, Hero's Comrades, Gruntilda, and Kim Kaphwan spirit battles.
• Dedede has his own damage effect known simply as Dedede, which applies to all hammer-related moves with the exception of Jet Hammer. It is identical to normal.
