Greninja (ゲッコウガ, Gekkouga) is a playable character in Super Smash Bros. Ultimate. It was officially revealed on June 12th, 2018 alongside Mr. Game & Watch and the rest of the returning roster. Greninja is classified as Fighter #50.

Billy Bob Thompson, Yūji Ueda, Frédéric Clou and Benedikt Gutjan's portrayals of Greninja from Super Smash Bros. 4 were repurposed for the English, Japanese, French and German versions of Ultimate, respectively.

Greninja is ranked 34th out of 82 on the current tier list, placing it in the B+ tier. This is a marginal rise from its 26th out of 54 placement in SSB4. Greninja's greatest strength is its mobility, as it has some of the fastest ground and air speed in the game. Coupled with a high jump height and a variety of moves with combo potential, especially its aerials, Greninja possesses a strong combo and rushdown game, allowing it to deal damage quickly and overwhelm opponents. In addition, Greninja also has many strong KO options, especially its forward air and smash attacks, that can all be comboed into at certain percents. This makes it stand out amongst characters of a similar archetype, as it has better KO power compared to other nimble, combo-heavy characters. Finally, Greninja's low stature makes it easier for it to weave through and dodge the opponent's moves.

However, Greninja also has several noteworthy weaknesses. All its aerials have a high start-up, which does not work well with its fast falling speed, as it hinders the disadvantage stage. In addition, its high jump can also work against it, as alongside the high aerial start-up and a mediocre grab, it means Greninja has little effective out-of-shield options, granting it one of the worst out-of-shield games in the game. Finally, Greninja's multi-hits are notorious for their inconsistent hitboxes, and as such, opponents have a great chance at falling out of them, greatly affecting Greninja's combo game.

Overall, Greninja fits its ninja archetype as a speedy, hard-to-hit character that can play aggressively and deal damage quickly, but on the other hand, it possesses more limited options when going on the defense. Greninja's representation was at its highest in the early metagame, as it possessed a strong playerbase spearheaded by Lea. Although the representation has since declined, dedicated Greninja players such as Tarik and Tsuna remain successful at the highest level of competitive play.

How to unlock

Complete one of the following:

• Play VS. matches, with Greninja being the 58th character to be unlocked.
• Clear Classic Mode with Donkey Kong or any character in his unlock tree, being the 6th character unlocked after Sheik.
• Have Greninja join the player's party in World of Light.

Greninja must then be defeated on Kalos Pokémon League (the Ω form is used in World of Light).

Attributes

Greninja, true to being a ninja-themed character, has very strong mobility; it has the 4th fastest walking speed, the 8th fastest run speed, the 10th fastest air speed, is tied for the 9th fastest falling and fast falling speed, the 2nd highest gravity, and possesses the 2nd highest jump height overall. However, unlike most characters who boast similar mobility (such as Sheik), Greninja boasts a surprising amount of KO options, good range on plenty of its attacks, and KO throws.

One of Greninja's most notable traits is its high mobility, which complements its grounded moveset. Greninja's dash attack comes out on frame 7 and has very low ending lag, as well as the ability to cross upon shields. Its knockback angle allows for many true follow-ups and strings over a large range of percents. Its neutral jab attack comes out on frame 3, making it a good grounded combo breaker. It can also lock, which gives Greninja access to potent punishes from opponents missing techs. Its down tilt is an excellent combo starter due to its low startup, ending lag and vertical launch angle. Greninja's up tilt is a frame 9 disjointed hitbox that acts well as an anti-air and can also be a combo starter. Its smash attacks are also reliable in their own right; its forward smash is quick for its range and power; its down smash is an excellent punishment option for ledge regrabs, as well as sending at a low angle; and its up smash is a potent combo finisher.

Greninja also has a very strong air game due to its aforementioned air speed and jump height. Its aerials are reliable for multiple situations, and all have low landing lag (except for its down aerial, at 30 frames). Its neutral aerial is a decent low percent combo starter due to it having incredibly low landing lag and a good launch angle. It can also KO at high percentages. Its forward aerial acts as a combo finisher from its combo starters and can KO moderately early. Its forward aerial's low landing lag and disjointed nature also make it safe on shield in many situations when spaced correctly. Its up aerial is a great juggling option with low all-around lag, and boasts good KO potential near the upper blast line. Greninja can also utilize its multihits to drag down opponents to create tech chase and jab lock situations. Its back aerial is a very fast follow up or offstage edgeguarding option. Its down aerial can be used as a mix-up to return to the stage from far above, as well as perform surprise combos on hit with both its meteor smash and sourspot hitbox.

Greninja's grab game is overall very effective, due to its grabs being among the longest ranges of any non-tether grab in the game. Its forward, up, and back throws can KO at high percentages. Its down throw acts as a middle percent combo starter, as well as a strong DI mix up, especially at higher percentages at ledge as a 50/50 between DI in and out in conjunction with its forward throw. Its up throw acts as a versatile combo starter that can lead to juggling situations. Because of this, Greninja has plenty of options off of a grab, as not one of its throws could be considered useless.

Finally, Greninja's special moves are effective in various situations. Water Shuriken acts as a versatile zoning tool, as well as a high-percentage KO option when fully charged. At low-to-mid percents, it is also a combo starter, allowing Greninja to rush down its opponent and follow up with any aerial attack or an up smash. Shadow Sneak works as an effective recovery mix-up, as well as a potent KO move from a good read or pseudo-combo finisher. Despite lacking an offensive hitbox, Hydro Pump is a good recovery move for its long distance, and can be used for gimping recoveries due to having windbox properties. Substitute is a counterattack with the unique attribute of being able to be aimed in one of 8 different directions upon a successful counter. These angled follow ups allow for Greninja to gain pseudo-follow ups, as well as KO earlier, by picking the optimal angle in regards to stage positioning.

However, Greninja is also flawed in many ways. One of its primary flaws is its inability to break out of a disadvantage state. While not as bad as in the previous game, Greninja still has difficulties escaping combos due to its fast falling speed and its aerials still having relatively high startup. This can sometimes be alleviated with its back or down aerials, but both are not very effective due to the back aerial's almost entirely horizontal hitboxes and the down aerial's landing lag. Another option is aerial Water Shuriken, which stalls Greninja in the air and can be used as a landing mix-up, as well as Hydro Pump landing mix-ups.

Another notable weaknesses is Greninja's multi-hit moves, especially its back and up airs, being notoriously inconsistent, allowing opponents to escape out of these moves. As both aerials are some of Greninja's best combo tools, the inconsistency greatly affects its combo game.

Greninja's biggest weakness, however, is its poor out of shield game, which is arguably the worst of the entire cast. Because of its high short hop, its aerials' slow startup, and lacking a fast grab (although it has good range), Greninja lacks an effective out of shield option faster than frame 14. While its back aerial is fairly quick at frame 5 (making it frame 8 out of shield), it is unable to hit opponents in front of Greninja and is very inconsistent at hitting opponents behind Greninja due to its high short hop. Jumping or rolling out of shield are potential options to reset the neutral game, but they are very predictable and easily read. Thus, when Greninja is pinned down in its shield, it has difficulty escaping the situation without being heavily punished. Combined with its vulnerability to combos, this gives it a poor defensive game.

Altogether, Greninja's playstyle requires players to think like an actual ninja: utilizing its superb mobility and fast attacks to rush down opponents; saving the slower attacks for potential mixups, mindgames and surprise KO options; and remaining unpredictable to prevent being trapped into disadvantageous positions.

Changes from Super Smash Bros. 4

Greninja has been greatly buffed in the transition from SSB4 to Ultimate. An assortment of its traits — such as its strong combo game and great mobility — that made up its playstyle have been further improved, while the general engine changes benefit said playstyle.

Most of the universal changes notably benefit Greninja. As with all other characters in the game, Greninja's already quick mobility is faster like most characters, which benefits its hit-and-run playstyle. The ability to run cancel into any ground move allows Greninja to further exploit its amazing ground mobility, allowing for easier setups into its combo starters, such as its up and down tilts and dash attack. The universally reduced landing lag on aerial attacks gives Greninja an easier time landing and comboing, while the universal 3-frame jumpsquat improves Greninja's ground-to-air potential. The implementation of spot dodge canceling and the changes to perfect shielding improve its potential punish game, due to its wide variety of combo starters and fast frame data.

Aside from the universal changes, Greninja has also received notable direct buffs. The biggest ones were to its grab game; its standing grab is faster, and its pummel, previously one of the worst in SSB4, deals less damage but is significantly faster, making it better all-around. Greninja's forward throw has higher knockback, allowing it to KO in an emergency, as with its up throw. Its up and down throws also have better combo and juggling potential due to the universal changes to mobility — the down throw notably now allows for potential KO confirms into its forward and back aerials Outside of its improved grab game, Greninja now has a new down tilt that has lower ending lag and sends at more favorable angles, and its dash attack sends at a higher angle, further improving Greninja's combo game. Water Shuriken has more range, improving Greninja's camping ability combined with its faster mobility. Substitute now slows opponents down and offers Greninja intangibility during all of its attack variations, bringing it in line with other counterattacks. Greninja's KO power has also been buffed, with its forward smash and forward aerial receiving higher knockback, its up smash connecting better into its second hit, and its down smash having faster startup.

On the other hand, Greninja is not without a few nerfs. Notably, the ability to tech footstools has made footstool combos much harder to pull off, which hinders Greninja's combo ability (specifically from its down aerial), though this is alleviated by the various buffs to Greninja's moveset. Substitute's attack variants are all weaker while also being more laggy overall, which compensates for the attack's new intangibility. In exchange for its buffed mobility, Greninja is now lighter, which brings it slightly more in-line with other combo-centric and/or hit-and-run characters, while not compensating much for its vulnerability to combos.

In terms of universal changes, some of them are as benefitial as they are detrimental to Greninja. The changes to air dodge mechanics slightly improve its previously below-average edgeguarding game, but also make it more vulnerable to combos. The increased shieldstun makes Greninja's own attacks much safer on shield, but also weakens its already poor out of shield game, forcing it to abuse the revamped perfect shielding. Lastly, the weakening of rage makes it slightly harder for Greninja to take advantage of it, despite compensating for its lighter weight.

Collectively, Greninja's strengths and weaknesses are more defined. It now performs much better as a hit-and-run, combo-centric character, with excellent mobility and various KO options and set-ups at a variety of percentages, but with its light weight and attributes making it just as vulnerable to combos while keeping its poor out of shield game. Despite its nerfs to its previous footstool combos, Greninja has been generally compensated due to the gameplay changes to the engine and the buffs to its moveset giving it a more traditional combo game. That said, various veterans have also been buffed to varying degrees, especially through game updates, while Greninja has comparatively received minor, unimpactful changes from them. Nevertheless, Greninja has improved from SSB4, keeping up with the rest of the cast in Ultimate.

Aesthetics

• Greninja's model features a slightly more subdued color scheme, more closely resembling its appearance in recent mainline Pokémon games. Its body and tongue appear to have a glossy, wet sheen. The textures on Greninja's tongue have also been adjusted.
• Greninja is slightly more expressive, squinting akin to how it does in the Pokémon anime in a few of his animations.
• Every move that once used water katanas now uses water kunai, similar to when Ash's Greninja uses Cut in the Pokémon anime.
• Greninja's tongue has less physics-based movement than the previous game.
• Greninja has altered animations for its sidestep, roll, and airdodge animations; it now disappears in a small whirlwind with leaves scattering, similarly to when Substitute is successful.
• Greninja's victory pose where it flips in the air and lands with its arms crossed has been altered: the camera doesn't move as much, causing Greninja's body to face away from the camera.

Attributes

• Like all characters, Greninja's jumpsquat animation takes 3 frames to complete (down from 4).
• Greninja walks faster (1.43 → 1.502).
• Greninja dashes faster (2.08 → 2.288).
  • Its initial dash is significantly faster (1.6 → 2.178).
• Greninja's air speed is faster (1.18 → 1.239).
• Greninja is lighter (94 → 88), worsening its survivability.
• Greninja's traction is higher (0.045 → 0.087).
• Forward roll has less ending lag (FAF 30 → 29).
• Back roll grants more intangibility (frames 4-14 → 4-15).
• Back roll has more ending lag (FAF 33 → 34).
• Spot dodge has less ending lag (FAF 26 → 25).
• Spot dodge has more startup with less intangibility (frames 2-16 → 3-16).
• Air dodge grants more intangibility (frames 2-26 → 2-27).
• Air dodge has significantly more ending lag (FAF 32 → 42).
• The changes to locking and the ability to tech aerial footstools hurts Greninja more than the rest of the cast, weakening notorious damage racking and KO setups it possessed in Smash 4.
• The increased shieldstun, shield grab startup and shield drop lag further hinder Greninja's poor out of shield game, now being arguably the worst out of the cast, as unlike most other characters, all its options that can bypass shield drop lag are either too slow or, in the case of its back aerial, cannot hit most opponents on the ground.

Ground attacks

• Neutral attack:
  • The first two hits have lower knockback (hit 1: 30 base/30 scaling → 20 / 25/25/15/15; hit 2: 30 base/50 scaling → 20/ 25/25/20), and keep opponents on the ground (hit 1: 70°/60°/80° → 361°/361°/180°/361°; hit 2: 70°/60°/90° → 361°). This allows them to connect better and jab lock.
  • The first three hits have smaller hitboxes overall (hit 1: 3u/2.5u/3.5u → 2.0u/2.0u/2.2u/2.2u; hit 2: 3u/2.5u/4u → 2.5u/2.8u/3.0u; hit 3: 5u/3u/3u → 3u/3.4u/4u). This reduces their vertical range.
  • The second hit deals more damage (1.6% → 2%).
  • The third hit deals less damage (3.5% → 3%), and thus less knockback.
  • The third hit uses stationary hitboxes rather than hitboxes connected to Greninja's arms.
  • The infinite has faster startup (frame 6 → 4), a shorter gap between hits (4 frames → 3), and has reduced knockback scaling (40 → 10) while gaining a hitstun modifier of 2 on each hit, allowing it to connect much more reliably.
  • The infinite has a lower hitlag multiplier (1× → 0.5×) and SDI multiplier (1.1× → 0.4×), making it harder to escape.
  • The infinite is comprised of one extended hitbox rather than two normal ones (size: 5.2u/6.2u → 5.5; Y/Z-offset: 7/7 → 7.5/7.5; Z-stretch: 13 → 14).
  • The infinite has gained a shieldstun multiplier of 4×. This allows it to lock opponents into their shields between each hit, and thus pressure them more effectively, but also allows them to cancel shieldstun and punish Greninja more easily if they shield 10 hits or more.
  • The infinite's finisher has three hitboxes instead of two, with different sizes (5.6u/6.6 → 4.2u/4.2u/4.8u) and positions (ID 0: 7 Y-offset/8 Z-offset → 7.5/9; ID 1: 7 Y-offset/16 Z-offset → 7.3/13 → ID 2: 7.5 Y-offset/16.5 Z-offset. This increases its horizontal range, but lowers its vertical range.
  • The infinite's finisher has reduced hitlag (3× → 2×).
• Forward tilt:
  • It deals more damage when angled (7.3% → 8.3%).
  • It has significantly altered knockback (angled up: 20/30/40 base / 110/90/70 scaling → 50 / 100/79/58; non-angled/angled down: 20/30/40 base / 110/90/70 scaling → 50 / 98/77/56).
    • This improves its KO power if sweetspotted, especially when angled up, allowing it to KO middleweights at around 170% from center stage.
    • However, this hinders its KO power if sourspotted, and removes its ability to lock opponents at low percents.
• Down tilt:
  • Greninja has a new down tilt: a downward hand sweep instead of a shin kick.
  • It has less ending lag (FAF 27 → 23).
  • It has altered knockback (60 base/40 scaling → 30/110). This slightly narrows its combo range at low percentages, but increases it from mid to higher ones, to the point it now allows for KO confirms at high percents.
  • It launches opponents at a more upward angle (70° → 79°/77°/75°), further improving its combo potential at high percents.
  • It deals less damage (7% → 4%).
  • It has smaller hitboxes (4u/3.5u/3u → 3u/2.5u/3u), reducing its vertical range.
• Dash attack:
  • The move has an altered animation with Greninja stopping halfway through the spin.
  • It deals more damage (7% → 8%), with base knockback compensated (100 → 90).
  • It has a longer hitbox duration (frames 7-10 → 7-11) and less ending lag (FAF 31 → 29).
  • It sends at a higher angle (60° → 70°). Combined with its lower ending lag and base knockback, this improves its combo ability.
• Forward smash:
  • It deals more knockback (30 base/101 scaling → 35/104).
• Up smash:
  • The first hit has a new hitbox that only hits grounded opponents with significantly reduced knockback (30 base/120 scaling → 20/10) and SDI multiplier (1× → 0.5×), whereas the previous hitbox can now only hit aerial opponents and has reduced knockback scaling (120 → 90). This makes the first hit connect more consistently into the second hit, no longer failing against opponents on platforms above Greninja.
• Down smash:
  • The move has much less startup lag (frame 16 → 11), with its total duration reduced as well (FAF 55 → 50).
  • The arms' hitboxes have been extended towards Greninja (Z-stretch: 0 → 7), and the move has one additional hitbox at each side during the last active frame, removing its blindspots.

Aerial attacks

• All aerials have less landing lag (12 frames → 7 (neutral), 15 → 11 (forward), 13 → 10 (back), 15 → 14 (up), 32 → 30 (down)).
• Neutral aerial:
  • The move has considerably less ending lag (FAF 65 → 53), making it much less likely to cause a self-destruct offstage.
  • The late hit has a longer duration (frames 14-16 → 14-19).
• Forward aerial:
  • It has much more knockback scaling (84 → 95), allowing it to KO roughly 20% earlier.
  • The move has a new, smaller extended hitbox directly in front of Greninja (size: 3u; Y/Z-offset: 7.5/8; Y-stretch: 8.5), removing its blindspot.
  • The move's two other hitboxes are smaller (5.4u/4.4u → 4.7u/3.7u), and one of them is offset further from Greninja (Y-offset: -7 → -8), creating a new blindspot between them.
• Back aerial:
  • The move has less ending lag (FAF 46 → 41).
  • It has bigger hitboxes (hits 1 and 2: 5u/4u/2u → 5.5u/4.3u/2.5u; hit 3: 5.8u/4.5u/2u → 5.8u/4.5u/2.5u).
  • The last two hits have less startup (hit 2: frame 8 → 7; hit 3: frame 13 → 11).
  • The first hit sends at different angles, one of them being a different autolink angle (365°/30°/30° → 367°/35°/35°). This allows it to connect better into the second hit.
  • The third hit deals more damage (4% → 6%), with its knockback scaling not fully compensated (120 → 95), allowing it to KO slightly earlier.
• Up aerial:
  • The fifth hit uses the autolink angle like the previous hits (85° → 367°), allowing it to connect more reliably into the final hit, and increasing the move's window for drag-down setups.
  • The first five hits have more base knockback (45 → 55), and the fifth hit no longer uses set knockback. This is overall beneficial to the move, as it inflicts more hitstun to opponents that further facilitates drag-down setups, without drastically disrupting its linking ability due to using the autolink angle.
• Down aerial:
  • The move has less ending lag if it misses (FAF 57 → 52), making it slightly safer to use offstage.
  • Greninja no longer loses its double jump when hitting with the move.
  • It has more ending lag when it hits an opponent (FAF 13 → 21), hindering its combo potential and making it less safe on shield.
  • Its hitboxes are smaller (clean: 6u → 4.3u; late: 7u → 5.2u) and higher up (Y-offset: -2 → 0.1), reducing its range.

Throws and other attacks

• Grab:
  • All grabs have more ending lag (standing: FAF 30 → 39; dash: 40 → 47; pivot: 36 → 42).
  • Standing and pivot grab have one frame faster startup (standing: frame 11 → 10; pivot: frame 15 → 14).
  • Dash grab has slower startup (frame 9 → 13).
  • Dash grab's grabbox doesn't extend out as far (Z-stretch: 20 → 17.5), reducing its range.
  • Pivot grab's grabbox extends further (Z-stretch: -22 → -25.3), increasing its range. It is now the largest non-tether pivot grab in the game.
• Pummel:
  • Pummel deals more hitlag (4 frames → 11), but has less startup (frame 6 → 2) and significantly ending lag (FAF 27 → 8). It is now one of the fastest pummels in the game, rather than one of the slowest.
  • It deals less damage (2% → 1%).
• The speed of Greninja's forward, back, and up throws is no longer weight-dependent. This improves up throw's combo potential against heavyweights, but worsens it against lightweights.
• Forward throw:
  • The move has gained a hitbox before the throw, increasing its damage (5% → 3.5% (hit 1), 4.5% (throw); 8% total) and allowing it to hit bystanders.
  • It launches at a lower angle (50° → 40°) with much more knockback overall (70 base/45 scaling → 65/100), to the point it has above-average knockback for a forward throw rather than being one of the weakest in the game, greatly improving its utility for setting up edgeguards and KOing at very high percents.
• Back throw:
  • Back throw deals more damage (8% → 9%).
  • It has an altered animation: Greninja turns towards the screen instead of remaining facing forward, and swings its arms horizontally towards its back to toss the opponent.
• Up throw:
  • Up throw has one frame less ending lag (FAF 44 → 43).
• Down throw:
  • Down throw has less ending lag (FAF 43 → 38), improving its combo potential.
• Edge attack:
  • Edge attack deals more damage (7% → 9%).
• Down taunt:
  • Down taunt has much more ending lag (FAF 80 → 110), further reducing its very limited utility.
  • Greninja now suffers hitlag when down taunt connects, but the opponent only suffers hitlag on the ground, as the air only hitboxes are flinchless, and thus cannot inflict hitlag. This effectively reduces the move's hit rate.

Special moves

• Water Shuriken:
  • Fully charged Water Shuriken travels faster (1.9 → 2.2), and has a longer maximum lifespan (32 frames → 36), significantly increasing its range to the point where it now has slightly more range than the uncharged version, rather than the other way around.
  • Opponents don't fall out of the fully charged shuriken as much as before.
  • Uncharged Water Shuriken has less knockback scaling (85 → 45).
  • Water Shuriken looks sharper.
• Shadow Sneak:
  • It can now be used multiple times in midair.
  • Shadow Sneak's shadow travels faster.
  • Both attack variants have less startup.
  • Forward Shadow Sneak has a new animation: it is a forward kick instead of a handstand kick. It launches at a much lower angle (48° → 36°), improving its KO potential.
  • Greninja now cloaks itself in a whirlwind before disappearing.
  • Shadow Sneak stalls less in the air (initial vertical boost: 2.1 → 1.8), hindering its recovery usage.
  • The shadow is notably darker, and the shadow's eyes flash red just before release. This makes it easier to predict the attack.
• Hydro Pump:
  • Hydro Pump now has an arrow pointing in the direction of travel, similar to Pikachu's Quick Attack and Pichu's Agility.
  • Hydro Pump can now be ledge-cancelled.
  • Greninja no longer loses its double jump if it is hit out of Hydro Pump.
  • The water shots have considerably reduced knockback (65 (base)/100(scaling) → 60/80), and smaller hitboxes (6u → 4.7u), greatly reducing the move's offensive utility.
• Substitute:
  • The counter window is longer (frames 8-29 → 8-34).
  • It has more ending lag if it misses (FAF 65 → 70).
  • Substitute slows down the opponent when the attack activates, allowing the attack to land more consistently.
  • All of the attack's variants have one frame faster startup (frame 41 → 40).
  • All of the attack's variants now grant Greninja intangibility during the attack (frames 1-37 → 1-56).
  • All of the attack's variants have slightly more ending lag (FAF 85 → 87).
  • The side variant has much less knockback scaling (100 → 85).
  • The up and diagonal up variants deal less damage (up: 14% → 13%; diagonal up: 13% → 12%) and have less knockback scaling (both: 100 → 95), noticeably hindering their KO power.
  • The down variant deals less damage (14% → 13%) and has less knockback (grounded: 100 scaling → 95; aerial: 50 base/100 scaling → 25/65). This hinders its KO power; particularly, the aerial version is no longer among the strongest meteor smashes in the game.
  • The diagonal down variant deals less damage (13% → 12%) without compensation on knockback, hindering its KO power.
  • Substitute has more vibrant particle effects.
• Secret Ninja Attack:
  • Greninja now turns into Ash-Greninja during its Final Smash.
  • Greninja and its opponents are no longer silhouetted during the attack.
  • The final hit has considerably less knockback scaling (160 → 125), reducing the move's KO potential to the point where it is now weaker than the similar final smashes of Robin and Mii Brawler, both of which also deal less knockback now.

Update history

Greninja has received a mix of minor buffs and nerfs and glitch fixes via game updates. Some important nerfs include removing the ability to cancel endlag with Hydro Pump, and the universal projectile shield damage nerf affected Greninja's safety and neutral game, making actions in general less safe. To partially compensate, other aspects like its down smash and pummel were made more reliable, and the increased shield size improves the potency of rushdown.

These changes did not affect Greninja in significant ways, and thus, Greninja's competitive standing has remained virtually the same since the game's launch.

1.2.0

• A visual glitch with Greninja's screen KO has been fixed.

2.0.0

• Down smash has a larger internal hitbox (Z offset: 0u → 0u-7u).
• Hydro Pump no longer instantly cancels Greninja's endlag when landing on a moving or slanted platform.

3.0.0

• Water Shuriken deals less shield damage (0 → (-1.5 to -5.5)/-4.5 (uncharged/fully charged, hit 6)).

3.1.0

• Fixed an unknown glitch that resulted in Greninja sliding while shielding.

4.0.0

• Greninja nows immediately descends when using down aerial after being launched, rather than air stalling.

7.0.0

• Overall shield size has been increased by 1.206×.

8.0.0

• Pummel has a larger hitbox (5u → 6u), allowing it to connect more consistently.

Moveset

• Greninja can crawl, wall cling, and wall jump.

Forward tilt		Rolling Kick (まわしげり, Roundhouse Kick)	7.3%	A hook kick which stops half way. It can be angled and can lock opponents.
Up tilt		Anti-Air Tongue (ぜつたいくう)	4.5%	Swings its tongue upwards. A good aerial combo starter and juggling tool due to its low knockback and somewhat disjointed hitbox. It can combo into itself at low percents and is a reliable way to connect into up aerial.
Down tilt		Shin Slash (すねぎり)	4%	Does a downward hand sweep. It sends opponents at an upward angle, making it a versatile combo starter. Notably, it can confirm a KO into an up smash rather easily.
Dash attack		Surface Kick (すいめんげり)	8%	Does a sweep kick. Is arguably one of the best dash attacks in the game, as it launches opponents at an excellent angle for combos, making it one of Greninja's best combo starters. Reliably combos into back aerial at virtually any percent, and can set up up aerial strings or drag-down combos with up aerial.
Forward smash		Water Kunai (みずくない)	14%	An inward slash with a water kunai. Deals good knockback and has good range. However, it has notable ending lag.
Up smash		Double Water Kunai (ダブルみずくない)	5% (hit 1), 14% (hit 2 clean center), 11% (hit 2 clean sides), 10% (hit 2 late)	Two reverse gripped inward slashes with water kunai, similar to Sheik's up smash. Greninja's strongest finisher, especially when hit clean. Can be combo'd into from a down-tilt at specific percentages for a KO.
Down smash		Water Kunai Shake Off (ダブルふりはらいみずくない)	13% (kunai), 11% (arms)	Hits both sides with water kunai. Due to it sending opponents at an semi-spike angle and coming out on frame 11, it is a quick and effective way to set up an edge-guard situation.
Neutral aerial		Water Burst (みずはれつ)	11% (clean), 6% (late)	Strikes a ninjutsu pose while emitting an exploding water bubble. Despite noticeable start-up lag for a neutral aerial(frame 12), it boasts great combo potential at low to mid percentages with its strong and weak hits and can KO confirm into up-smash at high percents with the weak hit. It can also KO at very high percents with its strong hit.
Forward aerial		Aerial Water Kunai (くうちゅうみずくない)	14%	Slashes with a water kunai. It has some start-up and suffers from high end lag, but it is a great tool in the neutral for spacing due to its disjointed hitbox and can be used for KOing. It is also safe on shield if spaced correctly.
Back aerial		Triple Kick (さんてんげり)	3% (hit 1), 2.5% (hit 2), 6% (hit 3)	Kicks backwards three times. It is Greninja's fastest aerial attack, although it is also one of the weakest aerials of its kind. However, this makes it a useful combo tool in return, as it can be followed up from a down throw, down tilt, as well as a dash attack. It can be a situational out-of-shield option if the opponent crosses-up on its shield.
Up aerial		Spiral Kick (らせんげり)	1.3% (hits 1-5), 3% (hit 6)	Does a upward corkscrew kick, similar to both Sheik's and Joker's up aerials. One of Greninja's best combo and KO tools, as it can juggle and KO effectively due to its great jumping prowess. It also allows for drag-down combos because it's multi-hit properties, although this requires precise timing to land it at the right time, as its final launching hit comes out too fast to set up drag-down combos otherwise.
Down aerial		Aerial Kick (きゅうしゅうげり)	8%	A diving double foot stomp. It acts as a stall-then-fall and bounces off opponents. The clean hit meteor smashes opponents while the late hit sends the opponent upwards, allowing for some situational combos.
Grab		Grab (つかみ)	—	Grabs with a whirlpool. While its standing grab is slow, it is among the longest-reaching grabs in the game.
Pummel		Grab Water Bind (つかみみずしばり)	1%	The whirlpool compresses the grabbed opponent. Fast but weak.
Forward throw		Push Away (おしのけ)	3.5% (hit 1), 4.5% (throw)	Shoves the opponent forward. Can KO at high percentages near the edge.
Back throw		Send-off　(さかおくり)	9%	Greninja leans forward and flings the opponent backwards. Like forward throw, its decent knockback gives it good edgeguarding potential at high percentages.
Up throw		Toss Up (なげあげ)	5%	Tosses the opponent upwards. One of Greninja's most useful throws, as it can combo into a up tilt or up aerial at low and medium percents and can even KO at later percents.
Down throw		Slam (たたきつけ)	5%	Slams the opponent onto the ground. It can combo into a down tilt, forward tilt, and dash attack at low percentages. It can combo into back aerial at medium percents and later into forward aerial as well at higher percentages with good timing.
Forward roll Back roll Spot dodge Air dodge		—	—
Techs		—	—
Floor attack (front) Floor getups (front)			8%	Sweep kicks around itself while getting up.
Floor attack (back) Floor getups (back)			8%	Sweep kicks around itself while getting up.
Floor attack (trip) Floor getups (trip)			8%	Sweep kicks around itself while getting up.
Edge attack Edge getups			9%	Performs a roundhouse kick while climbing up.
Neutral special		Water Shuriken	3%-10.8% (uncharged), 1.0% (fully charged looping hits), 9% (fully charged final hit)	Uses Water Shuriken, which can be charged. Depending on how long the move is charged, the shuriken will be larger and do more damage; however, the speed and distance will decrease as a result. At full charge, it hits multiple times and can kill with a Shadow Sneak follow-up at low and medium percents. It is also a decent KOing option at higher percents. A fully charged water shuriken that is reflected at a higher speed will have trouble landing the final hit on Greninja because of the looping hits not moving Greninja far enough for it.
Side special		Shadow Sneak	10% (normal), 12% (reverse)	Greninja moves its shadow along the ground; the way the shadow moves is relative to Greninja's position, and it can be moved further or closer to change how far Greninja teleports. After a short time or when the special button is released, Greninja disappears briefly, then reappears at its shadow while performing either a flip kick forwards or a stronger kick backwards (depending on control stick direction) to attack. While performing Shadow Sneak, Greninja cannot run, attack, grab, dodge or shield. However, it can walk slowly, jump and taunt. Has strong knockback and base knockback, which allows it to kill notably early when hitting the move offstage.
Up special		Hydro Pump	2% (per shot)	Uses Hydro Pump to propel itself in the inputted direction; it can be used twice. Each shot has a windbox effect that pushes opponents, making it a decent option for gimping predictable recoveries.
Down special		Substitute	13% (vertical), 12% (diagonal), 11% (horizontal)	Does a pose, and if anyone hits it while posing, Greninja will temporarily disappear, get replaced by a wooden log or a Substitute doll, and then appear behind the opponent and strike them. It deviates noticeably from other counters, as the attack itself can be angled in an inputted direction and launching the opponent in that direction (with the down input meteor smashing opponents, which makes it a good punish against reckless edgeguarders).
Final Smash		Secret Ninja Attack	6% (the mat), 50% (Total in the attack after mat)	Turns into Ash-Greninja and attacks the opponent with a mat. If an opponent is caught in the mat, Greninja will send them up into the air and strike the opponent repeatedly in midair with its kunai, before slamming them down with a final hit.
Down taunt			0.5%	While standing on one foot, Greninja holds out its hands, faces the screen, and summons small sprays of water. The sprays produce some knockback, though they're only able to KO Mario at 599% percent. A video showing the exact KO percentages at which each character can be KO'd can be found here. Unlike the rest of Greninja's taunts, this one cannot be cancelled (unless Shadow Sneak is being charged before using it).

•  Lea - The best Greninja player of all-time, having spearheaded Greninja's early metagame, ranking 21st on the Fall 2019 PGRU and placing 5th at several Umebura majors, as well as 7th at 2GG: Kongo Saga defeating Shuton and Dabuz. He remained the best Greninja player in the world until his hiatus in mid-2022, notably placing 7th at Kagaribi 7 during this time, and has sporadically competed since with mixed results.
•  Somé - The second-best Greninja player in Japan's early metagame, winning Karisuma SP 4 and TSC 11, and also placing 7th at Sumabato SP 4 defeating Etsuji, 9th at Umebura SP 6 defeating HIKARU, and 13th at Umebura SP 4. He took a hiatus from offline competitive play due to the pandemic, and did not return until 2023.
•  Stroder Ame - Plays a variety of characters, and primarily played Greninja in the early metagame. He was the second-best Greninja player in the world during this time, ranking 29th on the Spring 2019 PGRU. He is best known for winning Crown over Kurama, and has also placed 5th at Ultimate Nimbus defeating Tweek, 5th at Glitch 8 - Missingno defeating Cosmos and Maister, and 13th at 2GG: Prime Saga defeating ESAM. He has since switched to other characters, but continues to use Greninja as an occasional secondary.

He is one of the best players in Europe in the post-online metagame, having placed 7th at several European majors such as Ultimate Fighting Arena 2023 and King Con, and having multiple wins over Bloom4Eva at ranked events. Internationally, he is known for placing 5th at Rise 'N Grind 2023 defeating SHADIC, and defeating Shuton at Port Priority 8, Onin at GENESIS X, and ShinyMark at Battle of BC 5.
•  Tsuna - A known Greninja player in Japan since the early metagame, having placing 2nd at Karisuma SP 6, 5th at Sumabato SP 10, and 9th at Sumabato SP 11 during this time. He has since become the best Greninja player in Japan following Lea's hiatus, frequently placing at or near the top 8 at Sumabato events, including 5th at Sumabato SP 46 over Asimo and Jogibu.

Tier placement and history

In the early metagame, players quickly noticed that Greninja had been buffed from Smash 4, with improved versatility and speed, and despite losing its footstool combos, it gained a stronger combo game thanks to improved frame data on moves such as its dash attack, up throw, down throw, and neutral air. Greninja's high learning curve did not deter players such as Stroder, Jw, and Lea from seeing success with the character, and it became a popular pick in competitive play, culminating in the character peaking at 10th in terms of representation between July and December 2019. Due to Greninja's buffs and its strong representation, it was considered an upper-high tier character in the early metagame.

This perception shifted following the end of the online metagame, especially as Greninja players began pointing out frustrating traits in the character's moveset, most notably inconsistencies in its multi-hit moves. Furthermore, Greninja's best players from before the pandemic either became less active, changed mains, or had worse performance: for example, Lea would go on hiatus in 2022, with mixed results in the events he has attended since, while Stroder would begin playing other characters over Greninja. Although Greninja still saw strong results from players such as Tarik, its overall representation would drop, bottoming out at 45th between January and June 2022. Greninja's lower representation and more apparent flaws led to a colder reception than in the early metagame, and as such, it was ranked 33rd on the first tier list, towards the lower end of high tier.

Following the release of the first list, Greninja's results would noticeably improve, thanks to Tarik's results remaining strong and the rise of many other Greninja players, including Tsuna and Anarchy, in their respective scenes. Continued efforts from dedicated mains prevented Greninja from dropping further, and it only slid down a spot to 34th on the second list, ranking towards the middle of B+ tier, with this drop mainly being the result of the meteoric rise of Bayonetta and Corrin from the first tier list. Overall, although less common than the early metagame, Greninja remains a rather viable pick in the post-online metagame.

Role in World of Light

Finding Greninja in World of Light

Greninja was among the fighters that were summoned to fight the army of Master Hands.

During the opening cutscene, Greninja was present on the cliffside when Galeem unleashed his beams of light. Greninja leaped into the air to avoid one of the beams, which hit Lucario instead. Greninja was hit shortly after and vaporized, getting imprisoned by Galeem afterward along with the other fighters, sans Kirby. A puppet fighter cloned from Greninja is later seen alongside ones cloned from Fox, Samus, Link and other fighters.

Greninja was one of the many fighters that fell under Dharkon's control upon Galeem's first defeat, and it can be found in the Mysterious Dimension at The Dark Realm. It can be seen impeding the path, making it an obligatory unlock.

Greninja is later seen among several other fighters, making their last stand against Galeem and Dharkon. It also shows up in the bad ending where Galeem emerges victorious against Dharkon, witnessing Galeem engulf the world in light.

Spirit

Greninja's fighter spirit can be obtained by completing Classic Mode as Greninja. It is also available periodically for purchase in the shop for 300 Gold, but only after Greninja has been unlocked. Unlocking Greninja in World of Light allows the player to preview the spirit below in the Spirit List under the name "???". As a fighter spirit, it cannot be used in Spirit Battles and is purely aesthetic. Its fighter spirit has an alternate version that replaces it with its artwork in Ultimate.

Trivia

• In the Pokémon series, Ash-Greninja is only obtainable as a male. The fact that Greninja transforms into Ash-Greninja for its Final Smash, Secret Ninja Attack, implies that Greninja is a male in Ultimate.
• Greninja's new character portrait resembles its air dodge animation.
  • It also resembles Fox's character portrait from Super Smash Bros. 4, but with the arm and leg positions mirrored.
• Greninja's down taunt has a unique property where it will seemingly be absorbed by counters without triggering the counterattack, even against grounded opponents, despite the grounded hitboxes being standard hitboxes. This is because despite the grounded hitboxes being standard hitboxes that are counterable like any other hitbox, the aerial hitboxes actually take priority over the grounded hitboxes, and the aerial hitboxes are windboxes, which cannot trigger counters, but will still be negated by them. Since counters respond to both grounded and aerial hitboxes, the game treats this interaction as a windbox connecting with a counter and completely ignores the regular hitboxes that hit grounded opponents.
  • As Greninja's down taunt is the only attack in the game with direct windboxes that trigger hitlag for the user, this gives the unique appearance of the attack striking the counter, but being negated.
• Greninja's fighter number, 50, is the same as the number of its costume in Super Mario Maker. It shares this distinction with Inkling.
• Greninja, Ivysaur, Olimar, Little Mac, Ryu and Ken are the only base game characters to never appear as minions in any Spirit battles.
• Alongside Luigi, Greninja is one of two characters in Ultimate with a taunt that cannot be canceled, due to the fact that their non-cancelable taunts have hitboxes.
  • Strangely, this does not apply for Snake and Kazuya's taunts that have damaging hitboxes.
  • Greninja and Luigi are also the only two characters whose Classic Mode titles feature their names.
• Greninja can also be unlocked immediately after clearing Classic Mode as Sheik, referencing their ninja-like traits and movements.
• Greninja appears slightly tilted in its damage meter compared to its character artwork. This distinction is shared with fellow Pokémon series character Incineroar.
  • Coincidentally, both are final evolutions of starter Pokémon, and both have Dark as their secondary type.
  • Both are also found and unlocked in the Dark Realm in World of Light.
• Incineroar and Jigglypuff are the only Pokémon that are not encountered in Greninja's Classic Mode route.
• Oddly, Greninja does not vanish when performing a directional air dodge despite the sound effects playing. It shares this oddity with Rosalina & Luma and Palutena.
• In Ultimate, Greninja has a weight of 88, which almost matches its weight in Pokémon (in pounds), being 88.2 lbs.
• Because of Greninja's heavy throwing animation, it is unable to damage opponents with Wario's Wario Bike if thrown from the left, as the large tire will clip through the stage first and cause the bike to bounce off the ground. If thrown in such a way that it does not touch the ground during the throwing animation, it will be able to hit opponents.
