—Introduction tagline

Ken (ケン, Ken) is a playable character in Super Smash Bros. Ultimate. He was announced as a newcomer during the November 1st, 2018 Super Smash Bros. Ultimate Direct, alongside Incineroar and Piranha Plant. Ken is Ryu's Echo Fighter, thus being classified as Fighter #60^ε.

Reuben Langdon, Ken’s English voice actor since Street Fighter IV, reprises his role in the overseas versions. His Japanese voice actor since Street Fighter III: Third Strike, Yuji Kishi, reprises his role in the Japanese version.

Attributes

Being the more aggressive "shoto" compared to Ryu, Ken shares most of his attributes with some slight tweaks. As a medium-heavyweight of average size and mobility, Ken has decent frame data and damage output, as well as a dependable ground game due to his decent traction and above-average dashing speed. However, other attributes are polarized in an attempt to replicate the physics of Street Fighter; Ken's walking speed is extremely slow, and while his air speed is average, this is counteracted by his moderately high falling speed and short jumps. Additionally, he has very low air acceleration, and his air friction is uniquely locked at 0 while jumping, causing his jumps to follow a fixed "arc" unless the player steers them manually. Finally, Ken's fast fall increases his falling speed by 40% instead of the usual 60%. Overall, this grants Ken effective burst movement through dashing and jumping, but forces him to commit when approaching through the air and makes it difficult to land or move short distances.

Despite his average attributes, Ken is one of the most unique fighters in Ultimate, as he has access to many variations of both his standard and special attacks (a trait only shared with his base fighter, Ryu). His jab and tilts can either be held or tapped; tapped attacks are faster and usually combo well into themselves, while held attacks have greater KO potential and can serve as combo finishers. This also applies to his special moves (other than Focus Attack), which gain different effects like increased power or altered hitboxes when the button is held; they also see an increase in power when used with the original Street Fighter inputs. This effectively gives Ken two movesets—one for starting combos and racking up damage, and the other for scoring KOs. This versatility gives him access to potent true combos and mix-ups, leading to a strong punish game overall.

Ken's standard attacks are also unique in that most of them (even his tapped tilts) have a freeze frame multiplier of at least 1.8x, making them surprisingly safe on shield given their poor range and average damage output. This grants Ken an effective means of applying shield pressure and make some of his combo starters difficult to escape.

Ken's grounded moveset boasts considerable utility. His tapped jab and down tilt both hit on frame 3, making the former useful for relieving pressure, and the latter excellent for extending combos due to its launch trajectory being useful for followups, such as grabs. Tapped up tilt's low knockback, high speed and active frames make it effective for combos, either into itself, Shoryuken, or even down aerial at high percents near the ledge. Held down tilt can be canceled on hit into a special move, making it effective for shield pressure and damage-racking even at high percents. Down smash is quite powerful for its speed, and up smash lowers Ken's hurtbox while charging. Both tapped forward tilt and held jab are altered at close range, both becoming very potent at starting combos into his special moves. Additionally, Ken will automatically face his opponent when there is only one foe left (while standing on the ground), making it considerably easier to land his effective ground attacks.

Ken's aerial moveset is effective as well. Neutral aerial is a sex kick with low knockback and has only five frames of landing lag, making it useful for combos and kill confirms even at high percents. Forward aerial is quick, highly damaging and has good range; it can be chained into itself through repeated jumps, and its sourspot deals high shield damage. Up aerial has fast startup, a fairly active hitbox and decently high reach, making it useful for juggling. It is also reliably follows up into Shoryuken. Both up and down aerial are also able to auto-cancel from a short hop.

Complementing Ken's moveset and combo potential is his wide array of powerful finishers; some of his held tilts, smash attacks and aerials are very capable KO moves due to their high speed. Held up tilt grants upper body intangibility on frames 4-10 while hitting on frame 7, making it deceptively safe for KOs when combined with its speed and tapped up tilt setups. Up smash makes an effective substitute for held up tilt as a finisher, and its wide hitbox can catch aerial approaches. Ken's forward smash has long range, fast startup and is his strongest standard ground attack, making it useful for hard punishes. Back aerial is Ken's strongest aerial, and is fast and has good range despite its small hitbox. Forward aerial also serves as a decent KO move, enhancing its already impressive utility. Finally, down aerial is a powerful meteor smash with fast start-up and long duration, making it a deadly edgeguarding tool. Combined with his excellent combo ability, Ken's punish game is incredibly effective and versatile, being able to rack up damage or KO very easily after connecting with almost any attack.

Ken's signature special moves are also effective in their own ways. Hadoken is a large ki projectile, with three travel speeds based on input method; the standard version is capable of locking, while the input variation deals more damage. Tatsumaki Senpukyaku propels Ken forward, hitting multiple times throughout the attack, and potentially leading to followups. While Ken's signature Shoryuken serves as his main vertical recovery move, it is most well-known for its offensive utility, due to its sweetspot's high knockback, multiple powerful hitboxes, and brief intangibility (frame 5), making it both a powerful KO option and a potent anti-air. The input version of Shoryuken has increased KO power, even longer intangibility (frames 4-6, with arm intangibility frames 1-14), and lower landing lag, and can easily be chained into from Ken's other moves. Focus Attack grants Ken heavy armor against a single hit, and incapacitates opponents when at least half charged, allowing for followups. It can also be canceled on hit, after tanking a blow, or even while charging, allowing Ken to fake out with a shuffle that also provides horizontal recovery distance. His close held neutral attack, first two hits of tapped neutral attack, close tapped forward tilt, held down tilt, and all aerials can be canceled into special moves, allowing Ken to combo into Shoryuken for KOs, Tatsumaki Senpukyaku for extending combos, and Focus Attack for mixups and safety.

Outside of the standard special moves, Ken also has access to the Oosoto Mawashi Geri roundhouse kick and the Nata Otoshi Geri crescent kick using inputs only. The former is a powerful KO option at the edge with much more safety than his other special moves, while the latter is a combo extender that leads into either a forward smash, a down smash, or even a Shoryuken with proper reading. Furthermore, both attacks can be cancelled into Inazuma Kick, which deals heavy shield damage, further complementing his ability to pressure and deplete shields with his lengthy blockstrings.

Lastly, Ken has a long-distanced recovery and is surprisingly difficult to combo, traits not shared with most heavyweights. Tatsumaki Senpukyaku has large hitboxes and doesn't cause helplessness; this combined with canceled Focus Attack's armor and momentum boost grants surprisingly effective horizontal distance and protection. Shoryuken travels a good vertical distance, reaches above edges, and can stage spike reckless edgeguarders. Focus Attack also serves as an effective combo breaker, and neutral aerial and input Shoryuken both grant high speed and intangibility, and can even lead into combo or KO opportunities respectively. These traits allow Ken to survive to very high percents when used effectively, which also allows him to take full advantage of rage.

Despite his abundant strengths, Ken has his weaknesses as well, most of them shared with Ryu. Though his recovery travels a long distance, it becomes very short if extendable elements, such as Tatsumaki Senpukyaku, cannot be utilized. Focus Attack requires a brief charge before it can be canceled. Tatsumaki Senpukyaku's long duration and low damage makes it vulnerable to being interrupted by long-ranged attacks, and he can only use it once without landing or suffering hitstun. Ken's falling speed, low jumps and poor air acceleration make it difficult to recover from below the stage, as Shoryuken's recovery is almost strictly vertical and has high endlag, making Ken's vertical recovery easy to predict and interrupt. While Ken excels at shield pressure, his grab game is sorely lacking; his throws have high damage, but none of them have effective follow-up or KO potential. Down throw is his only combo throw at very low percents, and the extra utility of his throws (down throw instantly breaking shields, and up throw's kick KOing bystanders) does not apply in a 1-on-1 setting, making them situational.

Ken also suffers from a weak neutral game. Despite his good frame data (especially for his tapped tilts and neutral aerial) and decent running speed, his slow walking speed and short range hinders the otherwise great utility of his tilt attacks, which gives him trouble against characters who possess disjointed hitboxes, especially when combined with his tall stature. Ken's only projectile, Hadoken, is punishable if used carelessly due to its long endlag, weak damage and low priority. Aside from the advantages granted his neutral aerial and Focus Attack, Ken's fixed arc jumps make his aerial approach highly committal and thus very predictable. These issues force Ken to play patiently and take advantage of any opening, as he has trouble against opposing camping. Focus Attack's utility is also match-up dependent, as it becomes much less effective against fast or multi-hitting moves (such as Roy's forward aerial or Cloud's Cross Slash, respectively). Because Focus Attack is also Ken's main method of escaping combos, this makes him susceptible to certain combos and juggles due to his high weight and quick falling speed, and his slower fast-fall compared to most other characters occasionally makes it difficult to land safely.

Finally, Ken struggles to "force" early KOs, as his KO potential relies heavily on executing combos. While Ken does possess some powerful moves, like back aerial and sweetspotted forward smash, these usually require hard reads to land, and most of his other moves have low knockback scaling due to being tailored for combos. Ken's superb combo ability does largely compensate for this, but without accounting for opposing SDI, or without full knowledge of Ken's moveset, setups and combos, he can have a difficult time taking stocks. Ken's multihit special moves can be fallen out of if not used properly, leading to him being unsafe, or even punishable if he is not careful. Finally, the emphasis on Ken's unique inputs means that his non-input special moves have lower power, and a mere slip of the hand can be more detrimental than usual, at worst even causing a self-destruct while recovering.

Overall, Ken is a combo-oriented fighter with a fearsome offensive ability, as his unique mechanics deliberately give him access to powerful true combos essential to the competitive success of most characters; his ability to trap opponents in hitstun or shield pressure, multiple options for escaping or negating combos, and dependable recovery all make Ken very rewarding and unpredictable. However, his polarized movement, mediocre vertical recovery, and lacking approach make him difficult to play optimally. His high learning curve in particular is perhaps his biggest issue; much practice is generally require for his input specials to use them reliably and consistently, rather than accidentally inputting the wrong move.

In spite of his weaknesses and high learning curve, Ken's results and representation are more notable than Ryu's. Some players choose to utilize both accordingly to play to either's strengths, whether it be reliable damage and zoning or massive combo opportunities and options.

Differences from Ryu

Ken is considered the original "Echo Fighter" in fighting game history, but unlike other Echo Fighters in the game, Ken's differences extend beyond visual changes and damage distribution, using the gameplay differences from Super Street Fighter II Turbo onward to distinguish him from his mirror character, Ryu. He primarily trades Ryu's stronger knockback from single hits and zoning capabilities in exchange for more combo routes and damage-racking capabilities, similar to their differences in their home series. His grounded movement is slightly faster than that of Ryu's, and a handful of his attacks have entirely different properties as well.

Since Ken has multiple entirely different moves from Ryu, he is near-universally accepted to be the most unique Echo Fighter, being the only Echo Fighter that is a semi-clone. As such, he, much like fellow Echo Fighters Chrom and Lucina, is not expected to share a tier list spot with his base fighter, and is expected to be legally allowed to be used with his base fighter in Squad Strike.

Aesthetics

• As with all other Echo Fighters, Ken has unique taunts and victory animations.
• Unlike Ryu, Ken faces forward with a neutral expression instead of looking dejected or annoyed during his clapping animation.
• Ken is more vocal than Ryu.
  • Ken says "I'm ready for ya! Bring it on!" during his on-screen appearance rather than being silent like Ryu. His dialogue is the same as his fight entrance in Street Fighter IV.
  • Ken has more voice clips for taking light and middle knockback, similar to (and even more so than) Bayonetta.

Attributes

• Ken's walking (0.75 → 0.825), dashing (1.6 → 1.76) and initial dash (1.76 → 1.936) speeds are faster than those of Ryu, with his initial dash and run speeds being identical to those of Mario.
  • Ken's shield jump height is marginally lower than Ryu's, resulting in him landing 1 frame sooner.

Ground Attacks

• Held neutral attack is Inazuma Kick, a double-hitting axe kick resembling up throw. It is somewhat hard to land by itself, as its effective range tends to overlap with his close variant. It deals a large amount of shield damage.
• Neutral attack 3 has altered hitboxes and reduced hitlag (2 → 1.5).
• Ken's held forward tilt is his far standing medium punch, a straight with his right arm, as opposed to Ryu's Collarbone Breaker.
  • Held forward tilt is faster and deals more knockback at a lower angle.
  • Held forward tilt has less range and far less shield damage.
• Forward smash:
  • Ken's forward smash is based off of his standing heavy kick introduced in Super Street Fighter II Turbo.
  • It has less start-up (frame 15 → 13).
  • It has less range and does not make Ken travel forwards.
  • It deals less damage (16%/17.5% → 12%/16%), making it slightly weaker despite its higher knockback growth (98 → 102).

Aerial Attacks

• Neutral aerial:
  • Ken's neutral aerial is based off of his diagonal jumping medium kick in SFII, as opposed to Ryu's diagonal jumping light kick.
  • Due to it being a kick rather than a knee, the range of the move is increased compared to that of Ryu's neutral aerial.
  • It has less ending lag than Ryu's (FAF 36 → 28).
  • It has more startup lag (frame 4 → 6).
  • Its duration is shorter (4-31 → 6-17).
  • It has a sourspot on its clean hit that deals less damage (8% → 6.5%).
  • The late hit deals more damage on its sweetspot, but less on the sourspot (4.5% → 4% (sourspot)/6.5% (sweetspot).
  • The late hit has more base knockback (13 → 20).
• Up aerial:
  • Up aerial is based off of his neutral jumping light kick, a kick straight upwards.
  • It deals considerably less knockback, which hinders its KO potential, but makes it much better for combos.
  • It has less startup (frame 6 → 5) and has a longer duration than both hits of Ryu's up aerial (6 (first)/10 (second) → 5-9).
  • It deals less damage (11% (total) → 6.5%) and only hits once.
  • It does not grant partial intangibility.

Throws

• Ken's back throw, Hell Wheel, has him roll backwards twice, allowing him to cover more distance and move closer to the edge of stages from farther away.
• Ken's back throw takes a longer time to release opponents compared to Ryu's back throw.
• Up throw's kick hitbox comes out 2 frames later, without the animation being altered, reducing its vertical range, and making it less likely to hit Nana.

Special moves

• Ken has more input command moves than Ryu, which can only be used with the attack button.
  • He has Oosoto Mawashi Geri, an outward roundhouse kick from Super Street Fighter II Turbo similar to Ryu's standing held neutral attack that can be canceled into Inazuma Kick by holding the attack button, letting him use his special cancels without committing to the potential endlag of Shoryuken and Tatsumaki Senpukyaku and mix up his attacks. Inazuma Kick also deals a fair amount of shield damage, making it much riskier to block Ken during his blockstrings. At the edge, Oosoto Mawashi Geri makes for a reliable KO option from his special cancel normals.
  • Ken also has his Nata Otoshi Geri, a swiping roundhouse kick from Super Street Fighter II Turbo with a unique input (forward, down forward, down, special/attack) that Ryu does not have. He can cancel either the startup of the move or after the first hit and change it into his Inazuma Kick by holding the attack button. Its low knockback and angle make it useful for combos, leading into down smash, forward smash or a Shoryuken.

• Hadoken:
  • Hadoken contains an image of Ken's hands, as it does in the original Street Fighter II.
  • Hadoken deals less damage (7%/8% → 4.5%/5.5%), with even his strongest input Hadoken (6.8%) dealing less damage than Ryu's weakest standard Hadoken (7%).
  • Hadoken has slightly more startup lag (frame 12 → 13).
  • Ken does not have access to Ryu's Shakunetsu Hadoken, meaning that he lacks a multi-hit projectile.
  • Ken's Hadokens do not vary in speed as significantly as Ryu's do depending on how long the button is held. This reduces his space control and approaching options.

• Tatsumaki Senpukyaku:
  • Tatsumaki Senpukyaku hits multiple times, as opposed to Ryu's single hit.
  • Aesthetically, Ken slowly spins faster during Tatsumaki Senpukyaku.
  • Compared to Ryu's, Ken's Tatsumaki Senpukyaku does not lose its hitbox on hit due to its multi-hit nature. This makes it safer on shield.
  • If all hits connect, Tatsumaki Senpukyaku deals more damage.
  • Due to its multihit property and distance, Tatsumaki Senpukyaku can be used to drag opponents offstage far away at low percentages, being effective against opponents with poor recoveries.
  • Tatsumaki Senpukyaku has less endlag, allowing for followups after the move is complete.
  • Tatsumaki Senpukyaku does significantly less knockback compared to Ryu's.
  • The grounded version does not grant intangibility to Ken's leg.

• Shoryuken:
  • Shoryuken deals less knockback than Ryu's equivalent and hits at a slightly more horizontal angle.
  • Ken's medium Shoryuken hits two times, as opposed to only once.
  • Fully holding the special attack input performs a Heavy Shoryuken, which hits three times, and has a flame effect.
  • Although it KOs later, Ken's Shoryuken deals more damage and has powerful hitboxes throughout the move, in contrast to Ryu's Shoryuken losing strength the longer it is out. Shoryuken can also drag enemies upwards, letting it kill earlier when close to the top.
  • Ken can travel more horizontally during his Heavy Shoryuken. This makes certain combos possible and horizontal recoveries easier.

• Focus Attack:
  • Ken performs a spinning kick in his Focus Attack instead of a straight punch. The hitbox comes out 1 frame later for all variants, albeit with its total duration unchanged, allowing Ken to act 1 frame earlier on hit.
  • Focus Attack launches at a lower angle (60 → 45), and the uncharged version has slightly more base knockback (100 → 110), hindering its followup potential but aiding its ability to set up edgeguards.
    • The lowered angle improves the fully-charged version's KO potential on aerial opponents.
  • Ken does not lunge forward as far in his Focus Attack, slightly hindering its range.
  • Ken's Focus Attack has him kicking at a lower elevation than Ryu's punch, which makes him capable of hitting certain downed opponents that Ryu cannot (such as Zelda).

• Like Ryu, Ken has two unique Final Smashes, Shinryuken and Shippu Jinraikyaku, with the Final Smash activated depending on how far Ken is from his opponent(s). Shinryuken produces a giant pillar of fire with immense vertical range, which is similar to its appearance in the Marvel vs. Capcom series, which reused Street Fighter Alpha sprites in its 2D-era games. Meanwhile, Shippu Jinryaikyaku has Ken furiously kicking opponents before ending in a devastating series of hurricane kicks, much like his Guren Senpukyaku Ultra Combo II from Super Street Fighter IV and the ending of his Guren Enjinkyaku Critical Art from Street Fighter V, but is ultimately based on his Shippu Jinraikyaku Super Art from Street Fighter III. Shippu Jinraikyaku occurs when Ken initiates his Final Smash near an opponent. Otherwise, he will perform Shinryuken.

Update history

Like Ryu but to a much greater extent, Ken has been buffed overall in game updates so far, with most of his significant buffs coming in the 3.1.0 update. Many of his multi-hit moves connect more reliably and have a lower SDI multiplier, and more importantly, his moves that can be special-canceled have a longer window to do so, making his combos more consistent. His held, close neutral attack has completely changed for the better, now functioning as a reliable combo starter at a much wider percent range.

Update 7.0.0 buffed Ken even further. His overall shield is bigger, making it harder to shield poke him. His down tilt angle change was a mixed bag; it is now easier to combo into his Tatsumaki Senpukyaku, but it is now harder to combo into his Shoryuken. His pivoting leg is now invincible during his Tatsumaki Senpukyaku, making moves like Ness's PK Fire no longer work. The Tatsumaki is also stronger overall. The biggest change however, was to his down smash. It is now possible to cancel his down smash with a special move (at the expense of less shield damage), vastly improving his offense game. Another, albeit undocumented, buff to his down smash is that it is now possible to Kara Cancel the down smash charging animation. Kara Cancel was already possible but it could only be down during the first four frames of the down smash. Because of this, many players wonder if this change was an unintended side effect or intentional.

2.0.0

• Neutral attack launches opponents, making them easier to be hit.
• Neutral aerial auto-cancels earlier (frame 34 → 28), matching the move's interruptibility. This allows it to autocancel from a short hop.
• Forward aerial auto-cancels earlier (frame 41 → 38), matching the move's interruptibility. This allows it to autocancel from a rising full hop.
• Can no longer jump immediately after using down tilt.

3.0.0

• Edge attack deals less hitlag (1.5× → 1.1×).
• Shoryuken's animation has been slightly altered.
• Focus Attack sliding has been removed.

3.1.0

• Neutral attack 1 and 2 (light) can be canceled into a special move for a longer amount of time (1-7 → 1-11(jab 1)/1-12(jab 2)).
• Neutral attack (heavy, close) deals drastically less knockback (70 base/70 scaling → 25/15) and sends at a slightly more horizontal angle (85° → 80°), making it a much better combo starter even at high percents.
• Neutral attack (heavy, far)'s second hit deals more damage (6% → 10%) with knockback scaling not fully compensated (130 → 92).
• Forward tilt (light, close) can be canceled into a special move for a longer amount of time (8-14 → 8-24).
• Forward tilt (light, far)'s sourspot has less range (Z offset: 9u-5u → 6.5u-5u), effectively increasing the range of its sweetspot.
• Forward tilt (heavy) sends at a slightly more horizontal angle (38° → 34°).
• Up tilt (light) sends at more vertical angle when hitting airborne opponents, making it a better combo starter (66° → 75°).
• Down tilt (light) deals more hitstun (0 → 1).
• Down tilt (heavy) deals less knockback (70 base/23 scaling → 73/16), allowing it to combo at a wider percent range.
• Forward smash deals more knockback (26 base/100 scaling → 28/103-102).
• Down aerial can be canceled into a special move for a longer amount of time (1-12 → 1-17), making it identical to Ryu's variant.
• The first hit of Tatsumaki Senpukyaku has a larger hitbox when used on the ground (3.5u → 4.5u).
• Tatsumaki Senpukyaku has a lower SDI multiplier (1× → 0.5×).
• Shoryuken:
  • Shoryuken's hits connects more reliably and it has a lower SDI multiplier (1× → 0.5×).
  • Shoryuken's first hit no longer negates other attacks.
  • Shoryuken's grounded heavy version has more knockback growth (120(normal)/121(input) → 126).
  • Shoryuken's light and heavy aerial versions have more knockback growth (49 → 55 (light), 100 → 107 (heavy)).
  • Shoryuken's medium aerial version has less knockback growth (121 → 112).
• Command-input moves:
  • Nata Otoshi Geri has a lower SDI multiplier (1× → 0.5×).
  • Oosoto Mawashi Geri deals more damage (10% → 12% (both hits)) with knockback compensated (40 base/120 scaling → 41/103).
  • Inazuma Kick deals more damage (10% → 12%) with shield damage compensated (7 → 5).

4.0.0

• Ken now turns to face opponents after perfect shielding.

7.0.0

• Overall shield size has been increased by 1.125x.
• Held down tilt launches at a lower angle (64° → 55°) and has less base knockback (73 → 66). This makes it easier to combo into Tatsumaki Senpukyaku, but harder to combo into Shoryuken.
• Down smash can be canceled into special moves.
  • Kara Cancelling works even after charging down smash.
• Down smash has received negative shield damage (0 → -8/-6), preventing Ken from easily breaking shields by chaining it into special moves.
• Ken's pivoting leg is intangible during grounded Tatsumaki Senpukyaku. This prevents attacks that hit low to the ground from invalidating the move.
  • Tatsumaki Senpukyaku has altered angles (35° → 55°/31° (grounded), 55° (aerial)) and knockback (62 base/30 scaling → 45/59 base/20/25 scaling (grounded), 45 base/20 scaling (aerial)), allowing its hits to link more reliably.

9.0.0

• Shippu Jinraikyaku's trapping hit deals more knockback (40 set/0 base → 48/17), and the first two kicks upon successfully hitting an opponent have more horizontally extended hitboxes (Z offset: 8u—10u → 5u—10u), allowing them to connect more reliably.

Moveset

• In one-on-one matches, Ken always faces his opponent.
• A small flash will appear whenever Ken does the input command version of one of his Special Moves instead of the standard B input.
• Sound effects from the Street Fighter II series are used when Ken hits opponents, albeit heavily modified, instead of the typical knockback sounds. The intensity of the sound depends on the power of the move. Ken shares this trait with Ryu.

For a gallery of Ken's hitboxes, see here.

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

		Name	Damage	Description
Neutral attack		Inazuma Kick[2] (held, far)	1.5% (hits 1 and 2)	Tapped: A jab, followed by a short straight-punch, followed by a hook. The second hit is based on Ken's Street Fighter III close medium punch. The first and second hits can be special-canceled, and are also able to jab lock. Held (far): Ken performs his Inazuma Kick: a double-hitting axe kick. It is somewhat hard to land both hits, as the range tends to overlap with his close variant. This move causes Ken to slightly move forward, and deals a good amount of shield damage, making it useful for shield pressure. Cannot be special-canceled. Held (close): An uppercut similar to his held up tilt, but with significantly different properties, doing virtually no knockback and being special-cancelable. This makes it extremely potent for combos, reliably canceling into Shoryuken even at higher percents. Like his held up tilt, it renders his entire upper body intangible, giving it anti-air properties.
			5%
			6% (hits 1 and 2, held, far)
			12% (held, close)
Forward tilt			6.8% (tapped, far), 6% (tapped, close), 5% (arm), 10% (fist)	Tapped (far): The tsumasaki geri[3], a kick used in Karate. It launches the opponent diagonally upward. It is good for following up with a dash attack or forward aerial at low percents, and grants intangibility on his entire leg from frames 7-12. Cannot be special-cancelled. Tapped (close): An inward hook. The move causes the opponent to slightly shift towards Ken. It can lock, and can also be special-canceled. Held: A straight with his left or right arm. While it is faster and deals more damage that Ryu's Collarbone Breaker, it has less range and far less shield damage. It is based on his far standing medium punch. Cannot be special-canceled.
Up tilt			2% (tapped), 12% (held)	Tapped: The sok ngat[4], an uppercut-style elbow strike used in Muay Thai. An extremely fast and highly spammable move that can combo into itself. Held: An uppercut. It grants his entire upper body intangibility from frames 4-10, making it a surprisingly effective anti-air attack and KO move.
Down tilt		Light Ankle Kick (tapped) Heavy Ankle Kick (held)	1.6% (tapped); 7% (leg, held), 5.5% (foot, held)	Tapped: A crouching, Hapkido-style shin kick. It is extremely fast and highly spammable, much like his tapped up tilt. Any prone opponents will be lightly launched back onto their feet, allowing for longer combo strings. Held: A lunging, Hapkido-style shin kick.
Dash attack			12% (clean), 8% (late)	A flying kick. The clean hit launches opponents away, and can KO near the ledge. By contrast, the late hit is much weaker and launches opponents vertically, making it a potential combo starter.
Forward smash			16% (foot), 12% (leg)	A roundhouse kick. Ken's strongest horizontal KOing move, with the sweetspot on his foot being stronger than the sourspot on his leg. Unlike Ryu's forward smash, it has less range, and does not move him forward as much; it also has slightly less base knockback. Based on his standing heavy kick introduced in Super Street Fighter II Turbo.
Up smash			17% (clean), 13.5% (late)	Squats and then rises up to throw an uppercut. A decent vertical finisher, the move makes his hurtbox smaller while attacking, making this a good anti-air attack. Grants intangibility to his arm on frames 3-6.
Down smash			16%	A legsweep. It is Ken's fastest smash attack, deals an impressive amount of damage for an attack of its kind, and launches opponents at a semi-spike angle. However, it is rather weak for a down smash, and only hits directly in front of Ken.
Neutral aerial			8% (clean, bent leg), 6.5% (clean, leg/ late, bent leg), 4% (late)	A downward angled kick. While weaker than Ryu's neutral aerial, the move has increased range. The strongest hitbox is at Ken's bent leg. Hitting with it will also cause the opponent to slightly shift towards Ken, much like his close, tapped forward tilt. At mid percents, hitting clean with his bent leg will cause anyone behind Ken to move in front of him, allowing for combos into his special moves. It can be special-canceled. Based on his diagonal jumping medium kick in SFII.
Forward aerial			14% (clean sweetspot), 12% (late sweetspot), 9% (clean sourspot), 8% (late sourspot)	A flying kick. It has a sweetspot on Ken's outstretched leg, and a sourspot on his bent leg. The sweetspot launches opponents diagonally, while the sourspot launches them toward Ken. It can be special-canceled.
Back aerial			16% (leg), 13% (foot)	An outside crescent kick. Since Ken always faces his opponent in one-on-one matches, one must perform a reverse aerial rush in order to use it for edgeguarding. It can be special-canceled.
Up aerial			6.5%	A kick straight upwards. Unlike Ryu's up aerial, it only hits once, and his leg is not intangible. Can cancel into any of his special moves upon hit. Based off of his neutral jumping light kick.
Down aerial			12% (grounded opponent), 15% (aerial opponent sweetspot), 11% (aerial opponent sourspot)	A downward-angled cross. Against aerial opponents, the sweetspot on Ken's fist is a meteor smash that launches opponents at a rather diagonal angle, akin to a spike. It can be special-canceled.
Grab			—	Reaches out with his hand.
Pummel			1.3%	A knee strike while holding the opponent in the collar-and-elbow position. It is based on his Tsukami Hizageri (つかみ膝蹴り, "Grasping Knee Kick") throw in the Street Fighter Alpha/Zero games.
Forward throw			9%	The seoi nage[5], a Judo throw.
Back throw		Hell Wheel	12%	Rolls backward twice before performing the tomoe nage[6], akin to Pikachu's back throw.
Up throw			8% (throw), 15% (kick)	A stretch kick transitioned into an axe kick. The axe kick has a collateral hitbox that possesses impressive KO power against bystanders.
Down throw			3% (hit; throw)	Pins the opponent to the ground and performs a knifehand strike. Ken's only throw with combo potential, albeit a rather lackluster one. However, the actual throw's collateral hitbox deals enough shield damage to break even a full shield, though it is difficult to land due to it requiring bystanders to be directly in front of Ken.

Neutral special		Hadoken	4.5%, 5%, 5.5% (Standard), 5.6%, 6.2%, 6.8% (Input)	Quickly cups his hands to his side and then thrusts them forward to launch a blue ki blast from his cupped hands that deals low damage and knockback, and may cause tripping at low percents. As in the original games, Ken's Hadoken is weaker than Ryu's version. Since Ken does not have access to Shakunetsu Hadoken, he can only do two versions of the move: a small blue Hadoken (special button only), and a minutely stronger and larger inputted Hadoken (↓ ↘ → + attack/special). Combos well out of his tapped tilt attacks and aerials, and is mainly used to rack up damage due to its low damage outputs, knockback and slow speed. Both variants can cancel into his Final Smash. Like in the original Street Fighter II, Ken's Hadoken contains an image of his hands.
Side special		Tatsumaki Senpukyaku	3% (Standard, ground, hits 1 - 4), 3.4% (Input, ground, hits 1 - 4), 3% (Standard, midair, hit 1), 2% (Standard, midair, hits 2 - 4), 3.4% (Input, midair, hit 1), 2.3% (Input, midair, hits 2 - 4)	A jumping, spinning crescent kick. Unlike Ryu's version of the move, Ken's version hits multiple times, has less endlag, and the grounded version does not grant intangibility on his leg. Also, Ken will announce the move by name whether he uses the input or not (Ryu only announces the move if it was performed via input). If all hits connect, it can deal more damage than Ryu's version. The multi-hits can also drag opponents offstage at low percents, making it effective against characters with poor recoveries. However, Ken's Tatsumaki Senpukyaku deals significantly less knockback than Ryu's, repurposing the move from a KOing option into a combo starter and combo extender. Any of the hits can be canceled into his Final Smash.
Up special		Shoryuken	13% (Standard ground, fast tap), 8%/6% (Standard ground, mid-fast tap; hits 1/hit 2), 15.6% (Input ground, fast tap), 9.6%/7.2% (Input ground, mid-fast tap; hits 1/2), 2.2%/8%/6.5% (Heavy, Standard ground; hits 1/2/3), 2.6%/9.6%/7.8% (Heavy, Input ground; hits 1/2/3)	A leaping uppercut. Ken's Shoryuken deals less knockback than Ryu's equivalent and hits at a slightly more horizontal angle. However, it deals more damage and has powerful hitboxes throughout the move (in contrast to Ryu's Shoryuken, which loses strength the longer it is out). Shoryuken can also drag enemies upwards, letting it kill earlier when close to the top. Depending on how long the button is pressed, Ken's Shoryuken will hit a different amount of times: tapping the button fast causes it to hit once, tapping the button at a mid-fast speed causes it to hit twice, and holding the button performs Heavy Shoryuken: a flaming Shoryuken that hits 3 times. It grants him intangibility on frame 5. The command-input variant (→ ↓ ↘ + attack/special) deals more damage (especially the heavy variant), and grants intangibility to his arm from frames 1 to 14. Can cancel into his Final Smash.
Down special		Focus Attack	12% (Level 1), 10% (Level 2), 17% (Level 3)	Similar to Ryu's version, but with a spinning kick instead of a punch. Additionally, the uncharged version on grounded and aerial opponents, as well as the semi-charged and fully-charged versions on aerial opponents, launch opponents at a lower angle.
Final Smash		Shippu Jinraikyaku / Shinryuken	1.2% (hits 1 - 13), 13% (hit 14), 1% (initial hit), 3.2% (hits 1 - 4), 4% (hit 5), 4.3% (hits 6 - 10), 7% (hit 11)	Ken's Final Smash varies depending on range. At point-blank range, Ken traps the opponent with Shippu Jinraikyaku, a furious series of kicks, followed by devastating series of hurricane kicks. At any other range, Ken performs the Shinryuken, an uppercut which produces a giant pillar of fire with immense vertical range. Ken can cancel most of his moves directly into his Final Smash as well.

Roundhouse kicks

Unique to Ken, he has two additional special moves that are performed only by input. Both moves, each being a variation of roundhouse kicks, originate from Super Street Fighter II Turbo. These moves can only be used on the ground, with only the attack button.

Move	Input	Damage	Description
Oosoto Mawashi Geri[7]	← ↙ ↓ ↘ → + attack	12% (move), 10% (canceled Inazuma Kick)	An outward roundhouse kick, which resembles Ryu's far, held neutral attack. The input is the same as Ryu's Shakunetsu Hadoken: a half-circle input. By holding the attack button, he will cancel it into Inazuma Kick. The Inazuma Kick deals a fair amount of shield damage, making it much riskier to block Ken during his blockstrings. He also gains intangibility on his leg for frames 7 and 8. Works well as a safe combo ender, particularly at the edge where it becomes a powerful KO option. Can cancel into his Final Smash upon hit.
Nata Otoshi Geri[8]	→ ↘ ↓+ attack	5% (both hits), 10% (canceled Inazuma Kick)	A swiping crescent kick that hits twice, launching them into the air. This move uses a unique input, a reversed forward quarter-circle, that Ryu does not possess. While not always guaranteed, the attack leads into various followups and resets, including a forward smash. Much like Oosoto Mawashi Geri, holding the attack button will cancel into Inazuma Kick (cancels after the first hit only). As with his Oosoto Mawashi Geri, the Inazuma Kick cancel deals fair shield damage. Both hits can cancel into his Final Smash.

Canceling

Ken can perform a special move out of certain normal attacks, a mechanic known in his home series as special-cancelling. By pressing the special button or doing the command input after connecting with a normal attack on hit or on shield, Ken will cancel the endlag of the normal attack and perform the move. The normal attacks that can be canceled include the first two hits of neutral attack, tapped and held down-tilt, tapped up-tilt, and proximity forward-tilt and held neutral attack. He is also capable of doing so with his aerials. Special-cancelling allows Ken to perform blockstrings and hit confirms into Shoryuken for a kill, Tatsumaki for a combo, Hadoken for safety and pressure, and his roundhouse kicks for mixups and KOs at the edge. He can also bait the opponent out with a special cancel into a Focus Attack, further increasing mixup potential.

• Up: Punches twice, does a roundhouse kick, and raises his fist (similar to Ryu), while saying "Challenge me after some practice." In Japanese, he says "いくらでもかかってこい！" (Come at me as much as you like!), his win quote from Street Fighter II. Based off of his victory pose throughout the series, specifically his Street Fighter V variant.
• Right: Kicks twice (the first being the Nata Otoshi Geri, and the second being the Oosoto Mawashi Geri) and performs a beckoning gesture, saying "I knew I'd win! Hah!" In Japanese, he says "スパッと勝つと気持ちいいな！" (It feels good to win a spat!), one of his generic win quotes from Street Fighter V.

In competitive play

In the early stages of Ultimate, Ken and his original fighter Ryu barely had any representation. This was due to their high technical learning curve thanks to their fighting style inputs, and problems with approaching due to their mobilities and issues against projectiles. Due to the perception of Ryu at the time being lackluster from the nerfs he received from Smash 4, Ken was viewed more positively as he had access to his input kicks and slightly better mobility, though he was nonetheless perceived as a mid-tier at the time.

Patches slowly improved the perceptions of both Ryu and Ken, with most of their current buffs being shared between them. Patch 3.1.0. granted Ken some noteworthy buffs to encourage his close-quarters fighting style, with his held jab being retooled into an excellent combo starter, and giving more leeway for him to input special moves from many of his attacks. Ken's buffs widened the gap between his counterpart Ryu and significantly improved his perception in the metagame in comparison to him, as they granted Ken a newfound, formidable combo/damage racking ability that could end stocks from a single string of attacks. As a result, Ken gained more representation and was seen as a high tier character.

Following that, Patch 7.0.0. gave Ken even more buffs, with Tatsumaki Senpukyaku having intangibility on the legs and being able to cancel down smash into any special. Considering Ken's already high perception, this further improved him in the eyes of professionals, and he is often considered a dark horse candidate for a top tier or upper high tier. As with previous patches, Ken was commonly considered significantly better than Ryu due to his access to better mobility, a wider array of combos, a useful Tatsumaki Senpukyaku (which could initiate combos) and a feared KO tool in Shoryuken, which could KO as early as 90% and was easy to combo into. As a result of this, Ken has consistently been granted widespread representation from professionals especially when compared to Ryu, with players such as Riddles, Nito, Venom, Sandstorm, and takera earning good results with the character.

Role in World of Light

Finding Ken in World of Light

Although Ken does not appear in the World of Light opening cutscene, he was vaporized and later imprisoned alongside the rest of the fighters (sans Kirby) when Galeem unleashed his beams of light.

Ken was one of the many fighters that fell under Dharkon's control upon Galeem's first defeat. He can be found in Dracula's Castle behind an evil ghost; Akuma must be defeated in order to reach him.

Trivia

• Ken's pose in his official artwork is much like the pose in his Street Fighter III artwork.
  • It also resembles Ryu's pose in his Smash 4 artwork, only mirrored.
• Ken's attack on Wario's motorcycle in the character showcase video is a reference to the car smashing mini-game from the Street Fighter II games.
• Ken's inclusion makes Street Fighter the second third-party universe to have more than one fighter, after Castlevania.
  • Ken is also the second third-party Echo Fighter.
  • Additionally, Ken is the first Echo Fighter based on a third-party veteran, as Richter debuted alongside Simon.
  • Ken is the second clone to debut in their home series in the same game as the base fighter, after Falco in Melee, who debuted in Star Fox alongside Fox.
    • Coincidentally, they are the only two fighters who can fight a lone Crazy Hand in Classic Mode.
• Ken is the second newcomer in Super Smash Bros. Ultimate to be from a franchise that had its first character introduced in Super Smash Bros. 4, and the only one to be from a DLC-introduced franchise. His inclusion also makes Street Fighter the second franchise with a single character in Smash 4 to receive another playable character, the first for both instances being Animal Crossing.
• Ken is the first character revealed for Ultimate to share a reveal trailer with a character not from the same franchise, having been revealed in the same trailer as Incineroar.
• Ken's showcase of Shippu Jinraikyaku after a successful parry in his reveal trailer is a reference to "Evo Moment 37" (sometimes referred to as the "Daigo Parry"), a famous portion of an EVO 2004 match between top Street Fighter III players Justin Wong and Daigo Umehara, where Umehara's Ken successively parried each hit of Wong's Houyoku-sen as Chun-Li before following with the Shippu Jinraikyaku to win the match.
  • The moment is more directly referenced in a development image posted on Masahiro Sakurai's Twitter account, which features Ken parrying Zero Suit Samus's forward tilt. Within Ultimate, Zero Suit Samus is used to represent Chun-Li in her Spirit Battle. This picture was also posted during the timeframe of EVO Japan 2020, which Sakurai attended.
• One of gameplay showcase in Ken's reveal trailer depicts him taunting to Zelda at New Donk City Hall before attacked by Link; ironically, in Ken's home series, he has a girlfriend (who later becomes his wife) named Eliza.
• Ken and Richter are the only Echo Fighter newcomers with a CGI trailer as well as the only one with CGI footage for their splash art. Daisy did not have either, while Chrom and Dark Samus had only gameplay footage for their trailers and their official artwork for their splash arts.
  • Unlike Richter, Ken’s trailer can be played on his fighter page on the Super Smash Bros. Ultimate Official Site.
• Interestingly, Ken's appearance in Ultimate marks the fourth time in any game where his eye color is blue opposing to the usual brown after Street Fighter X Tekken and Street Fighter IV.
• Ken is one of the few characters who has a unique line while teetering: he voices a surprised "Uh oh!".
• Ken is the only character who speaks when he grab releases an opponent, voicing a quick "Whoops!" (やるな...!, You're good...!).
• Ken has the third highest amount of voice clips for any character in the game, with 62 clips. Kirby and Joker are the only characters who have a higher amount, with 97 and 98 total clips, respectively (counting the clips from the Phantom Thieves of Hearts).
  • Strangely, his Star KO clip is unavailable in his sound library, making him the only fighter with this distinction.
• Ken and Mario are the only characters that possess the Neutral typing when unlocking them in World of Light.
• Ken, Ivysaur, Greninja, Little Mac, Ryu and Olimar are the only characters to never appear as minions in any Spirit Battles.
• Like with Ryu, Ken uses Street Fighter sound effects for his attacks.
• If Ken is set as a CPU-opponent in Training Mode, all three CPUs will always face the player, much like on 1-on-1 matches. He shares this distinction with Ryu and Terry.
  • This also happens if Ken faces a single opponent in a team consisting of two or more characters in Team Battles, and in All-Star Mode when he appears.
• While Ken's Classic Mode route features opponents who are rivals to their main characters, Luigi is the only fighter not fought in his rival's Classic Mode route (being Mario's).
• Ken's description on the North American amiibo website is based on his description from Super Smash Blog.
• Ken, the Ice Climbers, R.O.B., Duck Hunt and Daisy are only non-DLC characters who don't appear in more than one Spirit Battles from their home series. Dr. Mario doesn't appear in any Mario Spirit Battles at all, and Cloud doesn't appear either since only spirits from the Final Fantasy universe are his fighter spirits. This is not counting Olimar, who appears only in Mockiwi spirit Battle as himself, but is fought in other Spirit Battles as Alph.
  • While the Mii Fighters technically represent the Super Smash Bros. universe, they appear in most of Mii-related Spirit Battles.
• A few of Ken's attack where he uses his legs or feet to attack, such as Focus Attack, are coded as arm or fist type attacks. This is likely a result of his attacks being copied from Ryu, as many of Ken's leg/foot attacks that are wrongly coded as arm/fist attacks are arm/fist attacks for Ryu.
