King K. Rool (キングクルール, King K. Rool) is a playable character in Super Smash Bros. Ultimate. He was announced as a newcomer during the August 8th, 2018 Super Smash Bros. Ultimate Direct. King K. Rool is classified as fighter #67.

Rather than being voiced by Toshihide Tsuchiya, who voiced the character since the 2007 title Donkey Kong Barrel Blast and the 2008 title Mario Super Sluggers, both games for the Wii, King K. Rool has a set of realistic crocodile roars and bellows, similar to how Bowser, Donkey Kong, and Diddy Kong emit realistic animal sounds in place of Bowser being voiced by Kenny James, Donkey Kong being voiced by Takashi Nagasako, and Diddy Kong being voiced by Katsumi Suzuki.

Attributes

King K. Rool is a character that ostensibly fits the mold of a super-heavyweight, being the second-heaviest character in the game behind Bowser and possessing a large array of powerful attacks with long range, but with below-average mobility. However, he has some characteristics that notably set him apart from his heavyweight peers; he has a wide variety of moves that serve multiple utilities, a great recovery, and other valuable techniques that aid his playstyle, focusing on punishing mistakes and zoning against horizontal approach.

King K. Rool's greatest strength is the immense utility of his moveset. Though many of his attacks are typical of super-heavyweights, he also has attacks that lack brute strength in exchange for unique attributes that contribute to his punish-focused playstyle. This is best shown through his character-specific perk, Belly Super Armor: attacks with this property gain short periods of this super armor, which can block incoming attacks during their duration. This mechanic gives him an advantage that allows him to win more exchanges than he would normally. Additionally, it affects a large amount of his moves, granting more safety on moves such as his forward tilt and dash attack to break through projectiles or difficult to punish attacks. As a result, Belly Super Armor heavily helps his approach and defense.

Alongside the utility of his Belly Super Armor, King K. Rool has effective tools for ground offense. His neutral attack has good range and speed, making it reliable as a quick spacing option. It is also the most damaging in the game. This is especially useful out of a foxtrot, which is faster than his normal dash speed, making him about as fast as Inkling. His tilts are very effective; for example, up tilt comes out very quickly, has decent knockback especially at the beginning, and has enough range to hit platforms above K. Rool. This can also be used to anti-air or prevent approaches from characters such as Lucina and Marth. It is also the most reliable move out of down throw, becoming a true combo from around 120% and scoring a KO on most characters. Down tilt can bury opponents or KO airborne ones, making it a potent punishment option. It also works at the ledge as a ledgehang punish or 2-frame option.

All of his smash attacks are incredibly powerful, and coupled with their unique traits and the belly armor on his up and down smashes, allow for very effective punishment. Forward smash deals heavy knockback regardless of where it hits, especially if angled upwards. It also confirms out of a down tilt bury at 70%, usually killing the opponent. Up smash functions as a quick anti-air, has a small spike hitbox and a third hitbox that punishes ground foes. However, only the first is really useful as the other two are weak. Down smash deals massive shield damage and lifts K. Rool's entire body off the stage from frame 4, allowing it to dodge most ground-hugging moves and makes it his best hard punish option. Overall, his smash attacks are all formidable for hard punishes.

His aerials are also fairly unique in their utility. Neutral aerial grants the longest duration of belly armor in K. Rool's moveset, making it a reliable combo-breaker or landing tool to prevent juggling. Neutral and forward aerials also act as sex kicks, making them effective for edgeguarding in a variety of situations. Forward aerial also deals non-tumble hitstun at 0%, confirming a grab. Up aerial has good start-up and decent kill power while also working as a niche platform movement out of a short hop. This is most effective when platforms are low, such as on Battlefield; it can also be used as a situational third jump while recovering, stalling K. Rool in the air while allowing it to potentially cancel out projectiles thrown at him. Down aerial and back aerial are meteor smashes, with the former coming out relatively fast, while the latter is very slow, but is also one of the strongest meteor smashes in the game. His up and down aerials utilize belly armor, but their utility is situational due to their hitboxes being separated from K. Rool's belly. King K. Rool's neutral, forward and back aerials are also safe on shield, which is unusual for a super-heavyweight character.

His special moves have a wide array of uses as well, with several efficient projectiles; the Blunderbuss is useful for edgeguarding purposes (such as forcing a situation where the opponent has to recover low, allowing for a down aerial) and throws out a Kannonball that can be sucked back in and aimed in a few directions. The Blunderbuss can also act as a command grab, sucking in opponents and shooting them out in different directions, with the forward reshoot in particular sporting very high knockback. The suction of the Blunderbuss is an effective ledge trapping tool, especially on stages with platforms. Since K. Rool can drop through platforms while still being able to move slightly, he can limit the opponent's options to get out of the ledge. The vacuum animation can also be delayed and is very quick to come out if a Kannonball is in play, allowing K. Rool to easily mix up the timings. Crownerang covers a large distance and grants him damage-based armor for almost the whole duration, and the late hit can set up combos into numerous moves. The pick-up animation also has some ways to be canceled, which can be adapted into the player's game plan.

Furthermore, King K. Rool has immense survivability: between his extremely high weight, above-average falling speed, and armor on numerous moves, King K. Rool has some of, if not the best longevity in the game; it is not uncommon for him to live past 200%. Additionally, his recovery move, Propellerpack, goes a remarkable distance for a heavyweight and is infamously hard to intercept vertically due to its respectable disjointed hitbox. This can be used to poke opponents on the ledge, then jump up with a forward or up aerial to regain advantage. It can also situationally be used to catch opponents near the ceiling to steal a stock, most notably on high recovery routes.

K. Rool has a very strong grab game: his grabs have very long range and all have 3 active frames, and his throws are also very strong and versatile. His up throw has him performing a jump and land over the highest platform over him. It is the second most damaging throw in the entire game, though it has mediocre KO potential without the aid of an high platform. His back throw has reasonably solid KO potential near the ledge with rage. At higher percents, his notorious down throw can lead into various mixups with tilts, up smash or aerials depending on mash speed. Forward throw does decent damage, can help put an opponent offstage and in a disadvantageous position, and lead into a dash attack for a true combo until around 20%. Once this is out of range, it is great for setting up okizeme. All of this is made even more effective with his excellent grab range; combined with his effective initial dash, this can allow for a string of grabs that strongly deters shielding.

King K. Rool has access to a large amount of advanced techniques. These techniques assist with movement, mixups, and even enable combos. As a result, he is a rather technical fighter that can be rewarding to a player looking for a simple character with a high learning curve. They are all somewhat practical and reward creative use, allowing players to build interesting playstyles of their own. This makes him easily accessed at a low level, while still being usable on a higher level of play. As long as the player is aware of the options that the design of these techs provide, King K. Rool will reward them for it.

However, King K. Rool's numerous advantages are also met with several glaring and exploitable weaknesses. His below-average speed spells trouble for him in certain matchups, and can make him easier to zone. Blunderbuss Kannonballs are slow to set up, and while they can occupy space well, fast characters can ignore it if they're already remotely close. Crownerang is also slow and can backfire very hard when missed, since the crown is a fairly powerful item that opponents can use to rack up damage very quickly. Gut Check is generally inferior to other counters due to having a hitbox only on his stomach, while having significantly higher endlag than most reflectors (around 30 frames if it fails), making it unreliable. This endlag makes it almost meaningless against some projectiles, such as Mega Man's neutral attack.

His massive weight and very large hurtbox size makes him extremely vulnerable to combos, and while his Belly Super Armor can help alleviate this, it is not foolproof: if K. Rool takes 28.02% of total damage to his armor over a short period of time, he will suffer a pseudo-shield break and be rendered immobile until his belly armor recovers. It also recovers at just .3% per second, making abuse quite difficult. Its limited HP punishes abuse of this mechanic if used frequently. Certain opponents such as Bowser and Ganondorf, which have very high damage outputs, can even break the belly of a careless K. Rool in a single hit. However, its effectiveness varies depending on whether clashing against his attacks is actually worthwhile. Additionally, due to their brief duration, his belly armor attacks are more reliable on quick, single-hit moves than long, multi-hitting attacks.

While K. Rool's ground game is decent and his grab and throw game are very good, his overall air game can be seen as mediocre. Despite having interesting attributes, including two meteor smashes, a lot of his aerials suffer from high ending lag, making many of them somewhat situational (especially up aerial). His down aerial has very high ending lag and start-up, making the potential punishes off of it very situational. While his down throw gives K. Rool extensive mixups and even kill confirms, it requires reads to be effective. It is also affected by the Bounce glitch, which adds even more inconsistency to the move. His up aerial has extreme ending lag (the highest of all aerials in the game), preventing King K. Rool from acting even after a jump (though platforms can alleviate this). While his back aerial is very strong and has a lingering hitbox, it has very high start-up lag. Additionally, none of King K. Rool's aerials autocancel in a short hop. His forward and back aerials require a full hop double jump to autocancel, while up aerial does not autocancel without being very high up. The high ending lag of his aerials makes fast-falling them offstage extremely risky, as it is possible to self-destruct before even getting a chance to recover, which depletes edgeguarding options. Due to the high overall lag of his aerials, K. Rool is unable to juggle for extended periods of time, and his aerial game is mostly constrained to a reactive playstyle. K. Rool's low air speed and overall poor aerial mobility further hampers his aerial capacity, giving him a limited air game.

Though a lot of his moves have decent start-up, especially for a super-heavyweight, an equal amount of them suffer from very high endlag, which means that King K. Rool gets easily punished if he fails to connect his attacks. Despite the wide array of tools he has at his disposal, K. Rool lacks many moves that can simply be thrown out quickly, as many of his attacks are punishable or force him to use up his belly armor. This ironically makes his approach ineffective despite the sheer amount of different, fast attacks he has; few of his attacks can maintain pressure without being exploited, and the lag can make moves like forward tilt a neutral reset at best. King K. Rool is also vulnerable to being pressured and rushed down due to a poor out of shield game; his up smash is nearly unusable out of shield due to the plank hitboxes being weak and slow to come out. His neutral aerial is also relatively slow out of shield and has poor range, especially behind him. As a result, K. Rool is particularly vulnerable to characters that can crossup his shield easily, since he effectively has no option to punish this kind of approach and has to resort to retreating or jumping away.

Crownerang, while a good move when it works, can also be his own worst enemy. If an opponent picks up the crown after it has been thrown, it leaves him without one of his best tools. The crown can actually be used to edgeguard against Propellerpack, or it can be thrown up to keep it from respawning. It is also very possible for opponents to combo with the crown, or pick it up again after throwing it, with very little counterplay available. The player must adopt an entirely different playstyle while the crown is on the field, or else risk losing a stock. As the pick-up animation takes 17 frames to complete, this also means that it can interrupt crucial combos, leading to the opponent getting away and resetting to neutral. While this is alleviated slightly through tech, it doesn't help a lot.

King K. Rool's recovery, while effective in theory, is very exploitable by many characters. Propellerpack is very linear, and a knowledgeable player can edgeguard him for long periods of time. It is immensely slow, and moving around with it reduces the vertical speed and leaves strong momentum, which can lead to a self-destruct if not accounted for. The hitbox doesn't entirely cover him horizontally, and as he cannot cancel the animation, he has to commit to it. He is usually forced to recover low, which is extremely dangerous due to how many characters have their own unique ways to beat him here. Moves from characters such as Piranha Plant and Villager have projectiles (Ptooie and forward smash respectively in this case) that can also counteract the vertical hitbox. It also leaves him very vulnerable to stage spikes, though LSI greatly alleviates this and allows him to tech to unreasonable percentages. The move can be angled to try and prevent this, though K. Rool usually won't recover without taking a large amount of damage. K. Rool also has very few ledge options; his only unique one is forward aerial, which requires frame-perfect precision to ledgesnap. Other than this, his ledge options are very limited—even Crownerang is too laggy to be used from the ledge reliably—and thus many characters can keep him there for a long time before finally killing him.

All in all, King K. Rool’s weaknesses outweigh his strengths. King K. Rool is an extremely resilient character that excels at keeping opponents out while punishing mistakes extremely hard. He enjoys playing a unique bait-and-switch playstyle, being a zoner that can switch to aggression whenever there's an opening and net a substantial punish. His damage output cannot be understated, with him often either getting a stock or leaving an opponent at kill percent. This ability to force reactions from his foe makes him unlike any other character in the cast, and creativity rewards the player with a decently versatile character. However, just like how he capitalizes heavily on mistakes and confusion, his own openings can be heavily punished as well, requiring him to play patiently.

Despite his numerous strengths, King K. Rool's competitive reception is generally negative. Early on considered to be a potential high/top-tier character and "broken" especially by casual players, King K. Rool's severe, heavily exploitable downsides have resulted in most top professionals ranking him as a low-tier character, with many of them even going as far as ranking him as one of the worst characters in the game. This reflects in his tournament results, as they are practically non-existent in North America and Japan, especially on national levels. However, thanks to dedicated players like Ben Gold and Muk, their results in Australia and Europe respectively are significantly better. Ben Gold in particular managed to win Battle Arena Melbourne 11, the biggest SSBU major so far in Australia. In addition, patches have given K. Rool a good variety of helpful buffs. Although his competitive reception still remains negative, his true viability remains to be seen.

Update history

King K. Rool has received a mix of buffs and nerfs during patches, but has been noticeably buffed overall.

Update 2.0.0's changes were a mixed bag: Blunderbuss's vacuum duration was reduced from 5 seconds to 2.5 seconds, his Propellerpack's hitbox was slightly reduced horizontally, and his down throw's bury time scaling was changed, being less effective at low percents but more effective at high percents. While the former two are direct nerfs, they do not significantly impact his playstyle. In addition, King K. Rool arguably benefits from the changes to his down throw, as they make certain kill confirms reliable (up smash) or even guaranteed (up tilt or dash attack at 130%).

Update 3.0.0 directly buffed King K. Rool, with his forward aerial's sweetspot being much easier to land, while his forward tilt gained new sweetspot hitboxes on his gauntlets, which allow it to hit buried opponents it previously wouldn't (such as Diddy Kong). Gut Check and up aerial, previously notorious for their endlag, had their ending lag reduced, which makes them slightly safer, albeit still risky. Like most projectiles, Crownerang had its shield damage reduced in update 3.0.0; however, this doesn't affect the move much as it already had low shield damage and was often used in order to facilitate dash grab approaches. Additionally, the nerfs to the projectiles of other characters, coupled with a slightly safer Gut Check, have somewhat improved his matchup against characters that are more dependent on projectiles, such as Samus.

After remaining unchanged for some time, update 6.0.0 gave King K. Rool more significant buffs. Neutral aerial's landing lag was noticeably decreased, forward aerial's clean hit was made stronger and easier to land, and his up aerial received a much longer hitbox duration with a stronger clean hit. Two of his specials were improved as well, with Blunderbuss having less startup, dealing more knockback with Kannonballs, and shooting vacuumed Kannonballs faster, and Gut Check having more range and less ending lag upon a successful counterattack. These changes greatly improve King K. Rool's neutral game and punishes compared to previous updates, though how they will affect his viability remains unknown.

2.0.0

A graph demonstrating the differences in time scaling between King K. Rool's down throw pre-patch (blue) and after the patch (red).

• Down throw has a different bury scaling formula (90 frames + 0.5*damage → 60 + 0.75*damage). This allows buried opponents to more easily escape at low percents, but more difficult at high percents. Specifically, it buries opponents for less time below 125%, and buries them longer above 125%.
  • This change makes direct KO followups beyond 125% more consistent, especially against opponents good at mashing.
  • It conversely makes it take longer for followups at low percents to start connecting, as well as makes it easier for opponents bad at mashing to avoid slower KO followups like forward smash below 125%.
  • The infinite jab combo (down throw to jab, repeat) that worked at 200%+ has been removed, now having the opponent "bounce" on the third loop.
• Blunderbuss:
  • Blunderbuss has a shorter windbox duration, (5 seconds → 2.5 seconds).
  • Blunderbuss no longer turns opponents invisible when KOing at their last stock.
• Propellerpack's horizontal hitbox is smaller, making it difficult to KO opponents straight to the upper blast zone and making it less safe when recovering. Most notably, it doesn't snap to the ledge as often as it used to.

3.0.0

• Forward tilt's sweetspot has more range.
• Forward aerial's sweetspot has priority over the sourspot.
• Up aerial has less ending lag (FAF 82 → 72).
• Up throw is no longer affected by wind zones for the duration of the move.
• Crownerang:
  • Crownerang deals less shield damage (0 → -4.5/-3.5 (traveling/returning)).
    • The crown item also deals less shield damage (0 → -3), slightly alleviating the shield pressure against K. Rool when the crown is stolen.
  • Fixed crown duplication with Villager or Isabelle's Pocket.
  • No longer increases the size of the crown while in an egg form from Yoshi's Egg Lay.
• Gut Check has less ending lag (Fail/Succeed: FAF 68/48 → 63/43).
• The desync glitch involving King Dedede has been fixed.

3.1.0

• Up aerial grabs the ledge more quickly when using the move (ledge lockout: 102 → 96). As an example of the change, full hop double jump up aerial will now cancel on the ledge during the endlag.
• Fixed an issue with Blunderbuss upon reflect of kannonball resulted King K Rool's windbox becoming stuck.

6.0.0

File:Blunderbuss (Kannonball Range).gif

Vacuum's new searchbox for Kannonballs in 6.0.0. Once it is completely stretched out, it remains as such until Vacuum is put away.

• Neutral aerial has less landing lag (13 frames → 9).
• Forward aerial:
  • Forward aerial's clean and mid hits deal more damage (14%/12% → 15.5%/13.5%) with knockback not fully compensated (40 base/78 scaling (clean), 35/80 (mid) → 36/76), improving their KO potential.
  • The clean and mid hits' sweetspot is larger (5.5u → 6.5u) and placed higher (Y offset: 7.5u → 8.5u (clean), 10.5u → 11.5u (mid)), increasing its range.
  • The mid hit lasts longer (frames 11 (clean)/12-13 (mid)/14-17 (late) → 11/12-14/15-17).
• Up aerial has a longer hitbox duration (frames 7-8 (clean)/9-16 (late) → 7-13/14-19), and the clean hit deals more knockback (85 base/56 scaling → 84/60), KOing at around 135% from ground level.
• Blunderbuss:
  • Blunderbuss has less startup (frame 30 → 25), with its total duration reduced as well (FAF 70 → 65).
  • The Kannonball is easier to vacuum, and has less base knockback (30 → 18), but much more knockback scaling (70 → 92), improving its KO potential overall.
  • Both the Kannonball and opponents are shot faster after being vacuumed. This makes it much easier for King K. Rool to recover offstage after using the move without self-destructing, increasing its utility as an edgeguarding tool.
• Gut Check:
  • The counter detection hitbox has more range (size: 6u → 7.8u, Y offset: 8.6u → 7.4u, Z offset: 6u → 4.4u), now covering some area below his belly.
  • A successful Gut Check has less ending lag (Normal/Reversed: FAF 42/53 → 38/45).
  • The counter hitbox and the counterattack's sweetspot have more range (size: 10u → 12u, Y offset: 11u → 12.5u, Z offset: 9u → 10.5u).

7.0.0

• Overall shield size has been increased by 1.011×.
  • The shield's center and K. Rool's posture while shielding has been adjusted to match.

8.0.0

• Belly Super Armor has more durability (14.01 HP → 18.01 HP), allowing it to withstand stronger attacks such as Falcon Punch from full durability, and improving its overall reliability. Considering the armor splitting damage between itself and King K. Rool, it's got effectively 36.02 HP.
• Dash attack:
  • The move has more knockback scaling (57 → 61 (clean), 48 → 55 (late)).
  • The clean hit has a longer duration, with the late hit's duration reduced accordingly (frames 7-11 (clean)/12-25 (late) → 7-14/15-25).
• Up smash's first hit deals more damage (15% → 17%) without full compensation on knockback (32 base/95 scaling → 31/90), improving its KO potential.
• Pummel has a larger hitbox (7u → 8u), allowing it to connect more consistently.
• Back throw launches at a lower angle (45° → 35°), allowing it to KO around 20% earlier.
• Crownerang has an increased armor threshold (6% → 12%).

Moveset

• K. Rool has a large and tall hurtbox while standing, walking, and jumping. However, he dashes on all four limbs, akin to real-life alligators and crocodiles, which makes his hurtbox significantly shorter.
• Fighter ability: Certain belly-based moves in King K. Rool's moveset (forward tilt, dash attack, up smash, down smash, neutral aerial, up aerial, down aerial, and side taunt) activate health-based super armor around his belly, known as Belly Super Armor. Each of the listed moves have this out for varying frames. However, taking damage with these moves cracks it, with K. Rool getting dazed upon it breaking completely after sustaining too much damage. The armor has 18 HP, but since the incoming damage is split 50/50 between K. Rool and his belly, it is practically 36 HP. It regenerates at 0.08 HP every 16 frames (about 0.3 HP per second). Attacks that hit K. Rool's belly super armor make a loud, distinct clanging sound as an audio cue, with a fixed 16 frames of hitlag. It is also possible to estimate the damage it has taken, with small cracks appearing at 11.5 HP (where 23% damage would break it) and large cracks appearing at 5.02 HP (where 10.04% damage would break it).

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

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

		Name	Damage	Description
Neutral attack			2.5%	A three hit combo consisting of a sumo-esque palm strike (comes out on frame 4), a claw swipe (frame 3), then a front kick (frame 5). The first hit can be repeated by holding the attack button, and can also jab reset on big body characters specifically, allowing for some interesting situations. The second hit resembles King K. Rool's standard attack from Donkey Kong Barrel Blast.
			2.5%
			7%
Forward tilt			11% (arms), 13% (palms)	Rears back and performs a forceful clap, similar to his archnemesis Donkey Kong's forward smash. Gains Belly Super Armor when he rears back to clap, making it a highly effective approach option with pivot cancelling. Sends at a semi-spike angle and is decently fast for its power (comes out on frame 12), KOing at 107% at the edge of Final Destination. It can be angled up and down, making it a decent anti-air tool when angled up, and it is capable of hitting the ledge when angled down. This move has impressive range due to a massive, disjointed hitbox surrounding K. Rool's hands. It does suffer from moderately high ending lag, though this flaw can be partially mitigated when spaced correctly. The combination of its range, Belly Super Armor, KO potential and ability to angle it up or down makes it not only one of the best moves in King K. Rool's kit, but also arguably one of the best forward tilts in the game.
Up tilt			11.5% (clean), 6.8% (late, arm), 8.2% (late, fist)	An uppercut. Has a wide hitbox, covering the front of K. Rool, and starts low enough to reach prone enemies. Almost as fast as his neutral attack, coming out on frame 5, which is very fast for a move with reasonably decent KO power. Loses power the longer it is out, with the sweetspot dealing rather strong diagonal knockback, and the sourspot dealing weak, mostly vertical knockback, which can potentially lead to another up tilt or up air. This move works well out of down throw due to its combination of speed and power.
Down tilt			13% (clean), 10% (late, non-burying), 8% (late, burying), 7% (late, quake)	A delayed sumo-esque stomp. K. Rool's foot buries grounded opponents, though it cannot do damage to an already-buried enemy. Much stronger on aerial opponents, and can KO at 104% at the edge of Final Destination. The stomp causes a shockwave near his foot. This deals weak vertical knockback to nearby opponents and allowing for moves like forward aerial to be used out of it. Starts with the non-bury hitbox on frame 13, before the bury comes out at frame 14. Forward smash is true out of this from around 70%, and frequently kills at that percent range. The hitboxes can hit some opponents under low platforms (such as the left and right platforms on Battlefield). Due to how buries work in Ultimate, it is possible to "store" knockback on a buried opponent using a weak attack, forcing them to get unburied over time and sent at the angle of the weak attack; this can create long combo strings at low percents.
Dash attack			15% (clean), 11% (late)	A belly-first lunge based on an attack from Donkey Kong Land. It covers a good distance and has incredibly fast start-up for its power (comes out on frame 7), but has very high ending lag. It also deals much less damage later into the attack. Has Belly Super Armor and can KO, allowing it to tank opposing hits (especially projectiles) as a risky approach. KOs at 102% at the edge of Final Destination, making it a very good move to use out of down throw through Instant Dash Attack, as it kills larger characters earlier than forward tilt.
Forward smash	↗		19.9% (sweetspot), 17.3% (close)	Dons a boxing glove, referencing his "King Krusha K. Rool" persona from Donkey Kong 64, and throws a straight punch. This move has a sweetspot on the glove and a sourspot on K. Rool's arm. It can also be angled and deals more damage if angled up or down, which gives it some versatility, depending on the angle Although the move is slightly faster than forward smashes of other super-heavyweights, it still comes out slow with a short-lasting hitbox (frame 19-20), and it suffers from extremely high ending lag even for its type, making it very punishable when missed. However, the move is very powerful, with the sweetspot KO'ing at 53% at the edge of Final Destination. The sourspot on his arm deals less knockback and damage, but is still moderately powerful. The boxing glove is also disjointed, which can be used to hard punish short hop approaches in niche circumstance. It's also very effective out of down tilt, as the move is fast enough to connect and KO at around 50-70% before the opponent mashes out.
	→		19% (sweetspot), 16.5% (close)
	↘		19.5% (sweetspot), 16.9% (close)
Up smash			15% (headbutt), 8% (late headbutt), 10% (plank); 3% (meteor smash)	A quick upward headbutt followed by a comical plank. The headbutt has a small hitbox, but has fast start-up (frame 6) and can KO from medium to high percents. It also has a slightly later hitbox on frame 10 that deals slightly less damage, making it somewhat inconsistent at times. The initial headbutt can be used to hit opponents on platforms above him, or as a risky anti-air move. It is King K. Rool's fastest out of shield option, though it is too situational and risky to be very effective for this purpose. It is also highly effective out of down throw, as it is able to hit opponents who mash out, being an effective kill-confirm at around 90-110%. The plank comes out later and has a big hitbox, but deals less damage and knockback, making it more suited for covering the headbutt or ledgetrapping at best. The plank animation weakly meteor smashes opponents, though this is ineffective for edgeguarding due to its low knockback. In addition, it is the weakest meteor smash in the game, failing to KO at realistic percents. It can be used to force tech situations or awkward placements off-stage, but these are highly situational and impractical. The sheer number of hits do make it useful for causing shield damage under platforms. Each hitbox is situated on K. Rool's head and body respectively, meaning it can miss entirely if used poorly. Additionally, the move has extremely high ending lag, with the first actionable frame being 72 and the last hit being on frame 23. The headbutt and plank KO at 100% and 162% at the edge of Final Destination, respectively. This move has Belly Super Armor shortly after K. Rool hops and before he flops onto the ground. There are intangibility frames on K. Rool's head when the sweetspot comes out.
Down smash			18% (body), 4% (quake)	A leaping belly flop, which causes a quake. Has Belly Super Armor during the leap, and deals heavy shield damage. As K. Rool physically leaves the ground when using the move, his hurtbox gets shifted into the air, allowing it to dodge ground or belly-level attacks to deal a hard punish. It is extremely powerful, being one of the strongest down smashes in the game, KOing at 50% at the edge of Final Destination. The move is very laggy overall, with its strongest hitbox coming out on frame 22, and it also suffers from very high ending lag, which makes it very punishable if used poorly. However, thanks to its initial hop and armor, the move is surprisingly hard to intercept despite its high startup. It also can be used on platforms against opponents that try to attack K. Rool from below. The quake is extremely weak, but it covers the high ending lag of the move somewhat, and it can occasionally lead to a forward tilt.
Neutral aerial			12% (clean), 8% (late)	Inflates his stomach and performs a splash based on an attack from Donkey Kong Land like his dash attack. Decently fast (comes out on frame 7), acts as a sex kick and has Belly Super Armor. In addition, it has very little lag in comparison to most of King K. Rool's moveset, and is his safest move on shield. Finally, it is also his fastest out of shield option that is somewhat practical, next to his neutral attack. Because of all of this, it is one of the safest and most versatile moves to use in K. Rool's kit. It can be used for landing, contesting aerials, approaching, and even gimping, as it beats out most recovery moves, even ones with hitboxes. In addition, due to its safety it can be used to pressure, and it can also combo into several moves, such as his neutral attack, up tilt, forward tilt, dash attack, grab and even situationally into down tilt, which can lead to devastating early kills.
Forward aerial			15.5% (clean, feet), 13.5% (clean, legs), 10% (late, feet), 8% (late, legs)	A dropkick, similar to Bowser's back aerial. Hitbox comes out on frame 11. Its sweetspot is at K. Rool's feet, which has a higher priority over the sourspot, making it easy to land. Has a very large hitbox with sweetspot being notably disjointed, giving it a very good range. The sweetspot has strong knockback, KOing around 100% near the edge of Final Destination. It deals disproportionately high damage, making it an very efficient damage racking tool. The move also acts as a sex kick, allowing it to be used for approaching or as a situational edgeguarding option. However, the move has relatively low landing lag, considering its power, huge, lingering hitbox, and relatively decent startup of 11 frames. This low landing lag combined with it's power and range makes it K. Rool's safest move in neutral when the move is being used while landing, being safe on shield, especially when spaced correctly. Its properties make it K. Rool's best combo starter at low percents, with sweetspot being able to lead into neutral attack, forward tilt, up tilt, dash attack and grab at low percents. It can even confirm down tilt thanks to it being +15 on hit with good landing at 0%. The sourspot on this move lies around the torso, and can be used well with down tilt as we. It has a late hitbox with drastically weaker damage and knockback, which has some niche combo utility at mid percents, being able to lead into grabs thanks to it not sending into tumble until around 65%. However, it is very hard to land consistently. Overall, the move is considered to be among the best and most versatile moves in K. Rool's moveset.
Back aerial			14.5% (arm), 19% (fist)	Turns around and does a delayed downward punch behind him, similar to Mario's forward aerial. It is very slow (comes out on frame 18), but it powerfully meteor smashes opponents if K. Rool's fist hits. Against grounded opponents, it launches them diagonally with extremely high knockback, being able to KO middleweights at 65% near the ledge, making it one of the strongest aerial attacks in the entire game. The larger, disjointed sourspot around the fist is significantly weaker, dealing rather weak diagonal knockback against both grounded and airborne opponents, failing to KO reliably until 160%. It also has a slightly lingering hitbox, making it an important tool in neutral when full hopped.
Up aerial			14%, 10% (late)	A headbutt that goes straight upward. Causes K. Rool to float slightly, giving it more reach. It has extremely high ending lag, preventing K. Rool from acting even if performed out of a double jump, making it risky to use offstage and making it the laggiest aerial in the game. However, is one of K. Rool's fastest aerial attacks (comes out on frame 7), and deals less damage if hit later. In addition to this, the early hitbox is among the strongest up aerials in the game, being able to KO at around 100% and even earlier if used near the upper blastzone, giving K. Rool a possibility to pick up very early kills with the move, especially with rage. The early hit has a large, disjointed hitbox much larger than K. Rool's head, which also lingers for a disproportionately long time. The move has Belly Super Armor while K. Rool stretches his head out, ending after the hitboxes are over. When short hopped, this move can allow K. Rool to move onto a platform, allowing for some movement options, and significantly helps with the issue of the move having high endlag. Like up smash, there are intangibility frames on K. Rool's head during the attack, making it disjointed and allowing it to beat projectiles or some other even reasonably disjointed moves such as Mr. Game & Watch's down aerial. This move can also be used for recovering from high to mid levels, as K. Rool can be moved from side to side while using the move.
Down aerial			12% (early), 9% (late)	Does a quick flip before performing a double foot stomp in a Superman pose. The hitbox is situated on K. Rool's legs. Decently fast (comes out on frame 14) and meteor smashes if the early hitbox connects, although the meteor smash itself is rather weak. If the opponent is hit by the early hitbox - but not meteor smashed - on-stage by this move, it confirms a wide variety of attacks. There is also a late hitbox with a sweetspot on the hip, with 20 extra stats in knockback growth, plus a sourspot on the feet. It also has Belly Super Armor after K. Rool stretches his feet out, giving it some safety.
Grab			—	Reaches out quickly with great range. However, his dash and pivot grabs are slower than his standing grab. If K. Rool misses, his left eye comically bulges in frustration.
Pummel			1.6%	Headbutts the opponent.
Forward throw			10% (throw), 7% (collateral)	Lifts the opponent over his head before slamming them into the ground, sending the opponent flying forwards. The slam possesses a collateral hitbox that can affect nearby opponents. Decent knockback. This combos into dash attack or a dash into neutral attack at 0%. It also has non-tumble hitstun at that point, making the combos extremely consistent.
Back throw			11%	Drags the opponent on the ground and throws them behind him. KOs at 124% at the edge of Final Destination, though Rage greatly assists its kill power.
Up throw			16%	Heaves the opponent over his head, leaps high into the air, and performs an Argentine backbreaker upon landing, blasting the opponent upwards. This is the most damaging throw in the entire game, but KOs late at around 180%. Stages with low upper blast lines and/or high platforms help mitigate this issue, as it carries opponents up in a similar fashion to Charizard's up throw.
Down throw		Piledriver	5%	Lifts the opponent overhead before slamming them into the ground head-first, burying them. Has the lowest damage output of K. Rool's throws, but this is compensated by its followup potential. K. Rool's most versatile throw overall, as well as one of his most versatile tools in general. Down throw follows up to numerous moves depending on the opponent's percent, including jab, up tilt, and up air at lower to mid percents, as well as forward tilt, forward and down smash at higher percents. It is also possible to infinite many fighters by throwing them, using jab while they're buried and re-grabbing them when they are released. However, most followups can be avoided if the opponent mashes out (especially since the throw itself is slow and gives plenty of time to react), making its kill setups unreliable at much higher percents. Only dash attack, forward and up tilts are able to follow up at 125% and kill reliably. However, up smash and up aerial can be used to discourage mashing and create 50/50 situations at lower percents, as the prior kills at 100% a lot of the time.
Forward roll Back roll Spot dodge Air dodge		—	—
Techs		—	—
Floor attack (front) Floor getups (front)			7%	Swipes his claws around himself.
Floor attack (back) Floor getups (back)			7%	Swipes in front of himself with one claw, then kicks behind himself with one foot.
Floor attack (trip) Floor getups (trip)			5%	Swipes both sides of himself with his claws.
Edge attack Edge getups			10%	Pulls himself up from the ledge and swipes forward with one claw. Has very long range, being just short of Bowser's.
Neutral special		Blunderbuss	13% (Kannonball), 12% (throw), 17% (relaunched Kannonball)	Pulls out a blunderbuss and fires a Kannonball forward, while donning the pirate hat worn by his alter-ego "Kaptain K. Rool" in Donkey Kong Country 2: Diddy's Kong Quest. Only one Kannonball can be in play at one time, with another being usable after around 2.5 seconds. After a Kannonball is fired, the special button can be held to use the blunderbuss's vacuum function, sucking in nearby enemies or the Kannonball itself (though the move will eventually cancel after several seconds), similar to Kirby and King Dedede’s Inhale. K. Rool can drop through soft platforms while vacuuming with his blunderbuss, and he also can move left and right as well while airborne, which is very useful for ledgetrapping. Once it sucks something in, K. Rool will immediately launch it out at a slight angle upward in front or behind him, or directly upwards, depending on the held direction. The blunderbuss "throw" KOs at 100% near the edge of Final Destination, though it deals lower knockback upwards or if reversed. A launched fighter or re-launched Kannonball is capable of KOing as early as 70%, with the Kannonball lingering while doing minor damage after the first hit.
Side special		Crownerang	9% (projectile), 7% (returning), 6% (item)	Takes off his crown and flings it forward, similar to Boomerang. Has 6% damage-based armor while K. Rool is throwing his crown. Deals less damage when returning. Unlike Boomerang, it cannot be smash thrown. The crown will attempt to return to K. Rool while flying, though it will slowly lose altitude. Only one crown can be thrown at once. If K. Rool fails to catch it, the crown will drop as an item for anyone else to use, and will reappear on his head after 12 seconds or if K. Rool touches it again (does not count if the crown hits him as a thrown item, or if the crown is from another K. Rool). The pickup animation can be cancelled through using a move or "unavoidable" animations such as jumpsquat when coming into contact. It also has a number of advanced techniques, such as Crown sliding.
Up special		Propellerpack	3% (propellers)	Equips the Propellerpack worn by his alter-ego "Baron K. Roolenstein" in Donkey Kong Country 3: Dixie Kong's Double Trouble, and flies upward. Especially for a heavyweight, this recovery covers an excellent amount of distance, allowing K. Rool to fly from one end of Final Destination to the other, though changing direction is difficult. Upon reaching peak height for a moment, K. Rool will slowly drift down while flapping his arms. Pressing down will make K. Rool enter his helpless animation, falling faster and having less landing lag. The propellers above K. Rool deal multiple weak hits, protecting him from edgeguards while even allowing him to drag opponents to the top blast line, though this can be DI'd out of if it hits more than 3 times.
Down special		Gut Check	1.5× (sweetspot), 1.05x (sourspot), 1.5x (reflected projectiles)	Puffs out his stomach and retaliates against attacks. It works like a counterattack and can also reflect projectiles. However, the counter hitbox is centered on K.Rool's stomach, making the rest of his body vulnerable (most notably his face), much like the Melee and Brawl versions of Toad. It has a damage multiplier of 1.5x, making it tied with Counter Throw for the second highest damage multiplier out of any counterattack in Ultimate, surpassed only by Tetrakarn. When reflecting, the stomach has a lingering hitbox that also scales with damage. This can make it KO at very low percentages using moves like Samus's Charge Shot to boost damage. This is usually seen when projectiles are reflected from close range.
Final Smash		Blast-O-Matic	3% (stomp), 10% (tackle), 25% (laser), 10% (throw)	K. Rool stomps, stunning any nearby opponents, and lunges forward while catching those in his path. If at least one opponent was caught, a cutscene plays in which K. Rool sits on his throne on Crocodile Isle before firing a massive laser from his Blast-o-Matic cannon. The laser then fires through Donkey Kong Island, destroying the island and dealing massive damage on the victims.

In competitive play

Upon Ultimate's release, many players noted King K. Rool's numerous strengths that were never seen before on a super-heavyweight character, namely two projectiles, his unique Belly Super Armor mechanic, down throw that in theory leads to very early kill confirms, rather good startup on many moves, and a very long-ranged recovery. This, in addition to his other strengths more typical to his weight class, caused the majority of top professionals to consider King K. Rool a potential high or even top tier character, while also getting a notorious reputation of being "broken" among less experienced players.

However, it quickly became apparent that King K. Rool wasn't nearly as good as players thought, as he also has some of the nastiest downsides in the entire game to counter his strengths. This includes a gigantic hurtbox, little options to break out of disadvantage, and high endlag on his moves to offset their "unchallengeable" startup and exploitable mechanics on many of his strengths, namely his extremely slow and predictable recovery; linear, laggy projectiles; his Belly Super Armor being surprisingly breakable and not scaling with the 1v1 multiplier; and his down throw being easy to mash out until higher percents, rendering seemingly "broken" kill confirms not true until higher percents. While he can use mash deterrents and reads to "game" the system, these are inconsistent by nature and very unsafe if they fail. In addition, his two best players at that time, Ito and KOSSismoss, both went inactive from tournament play soon after release. Compounding this, King K. Rool got nerfed in patch 2.0.0. This made his already negative perception even worse than before. Because of all of this, almost every top professional saw him as one of the worst characters in the game.

King K. Rool later received small but helpful buffs in patch 3.0.0, although they weren't significant enough to address his significant flaws, and his competitive reputation remained poor. Nevertheless, it improved his representation. While still typically ranked very low, players such as Ben Gold. KirbyKid, and Muk began to earn results that would question his reputation as a low/bottom tier character. This is evident when Ben Gold managed to win a B-tier tournament at Battle Arena Melbourne 11 with solo King K. Rool. Finally, his more impactful buffs in 6.0.0 have also further shifted his opinions to a more positive side, as it alleviated some of his weaknesses. While many players still view him rather lowly, others have shifted into a more positive view. Some of them, such as ESAM and MVD, goes even as far saying that King K. Rool is not a low/bottom tier, but a mid tier character instead. How much better he is, as well as his true viability, however, remains to be seen.

King K. Rool's opponents are among the heaviest characters in the game. The boss of this route is Galleom, likely as a reference to his hulking proportions and his postures being similar to K. Rool's arch-nemesis, Donkey Kong. Additionally, "Galleom" is spelled similarly to "Galleon", which can be a reference to the song most associated with King K. Rool, Gang-Plank Galleon.

Role in World of Light

Finding King K. Rool in World of Light

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

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

King K. Rool was one of the many fighters that fell under Dharkon's control upon Galeem's first defeat. He can be found on a ship in the Mysterious Dimension sub-area, guarded by the spirit of fellow pirate, Risky Boots. To reach his location, the player must defeat the spirit of Trevor C. Belmont, the right answer to a quiz question of which Spirit assisted Alucard in defeating Dracula.

  • Additionally, this is currently the only Nintendo Switch game in which King K. Rool appears.
  • DK Jungle Climber, released in Europe on October 12 and Australia on November 1, 2007 marked the last time King K. Rool physically appeared in these regions.

• King K. Rool is the fourth of five newcomers to be announced in Ultimate that was previously featured as a Mii Fighter costume in Super Smash Bros. 4. The other four are Inkling, Daisy, Chrom, and Isabelle.
• One of the poses King K. Rool strikes in his victory animations is the same one he poses in his official artwork.
• According to Masahiro Sakurai, King K. Rool's inclusion in Ultimate was a result of his popularity in the Super Smash Bros. Fighter Ballot.
  • As a result of King K. Rool's inclusion, fans of the character issued a thank you letter to Masahiro Sakurai and Nintendo of America for including him as a playable fighter. The letter was signed by fans, and Nintendo of America even wrote back to the fans, expressing gratitude towards them for the fan letter.
• Like King Dedede, Lucina, Simon and Richter, K. Rool's name is pronounced differently between the different international versions of Ultimate. It is pronounced "King Kay-Rool" in English and "King Kruel" in Japanese.
  • This is the first time that the English name is spoken verbally in a game. The first time it was spoken verbally was in the pilot episode of the Donkey Kong Country animated series, although it was alternated with the pronunciation "King Kuh-Rool" before the pronunciation of "King Kay-Rool" was dropped entirely.
• King K. Rool is the second character in the series whose back aerial meteor smashes opponents, the first being Lucas.

• During early gameplay footage released by Nintendo showing King K. Rool facing off against Snake, the announcer did not say, "wins" after saying King K. Rool's name on the victory screen. This was later fixed.

• Pausing and zooming in on and around King K. Rool during his side taunt reveals a gap between his scales and his belly armor.
• King K. Rool is one of five characters whose unlocking battle in World of Light is not on either Final Destination or an Ω form. The other four are Peach, Daisy, Toon Link, and Mii Gunner.
• If King K. Rool gets grabbed by a grab that uses a unique animation on capturing characters (Snake's grab, Ganondorf's Flame Choke, etc.) while using his forward smash, the boxing glove will remain on his hand until he gets released.
• King K. Rool's animation when using the Home-Run Bat's forward smash utilizes a one-handed swing, similar to his batting stance in Mario Super Sluggers.
• In the Canadian French version, 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 K. Rool).
