'''R.O.B.''' ({{ja|ロボット|Robotto}}, ''Robot'') is a playable character in ''[[Super Smash Bros. 4]]''. After initially being [[leak]]ed on August 19th, 2014 as part of the [[ESRB leak]], his return to the series was officially announced on [[Super Smash Bros. 4 Official Site|''SSB4''{{'}}s official website]] on October 9th, 2014, during which {{SSB4|Ganondorf}} was also announced.<ref>[http://www.escapistmagazine.com/news/view/138070-Secret-Super-Smash-Bros-Characters-Revealed-by-Nintendo#&gid=gallery_3377&pid=1 More "Secret" ''Super Smash Bros.'' Characters Officially Revealed]</ref>

R.O.B. retains his realistic robot sounds that he had in ''[[Super Smash Bros. Brawl]]''.

R.O.B. is ranked 35th out of 54 on the [[tier list]], placing him in the D tier. This is a moderate drop from his placement in ''Brawl'', where he was ranked 18th out of 38, which is his worst placement in the series. R.O.B.'s boasts a strong zoning game and recovery: [[Robo Beam]] and [[Gyro]] are [[charge]]able, long-ranged projectiles, while [[Robo Burner]] is versatile; covers impressive overall distance; and is complimented by his much faster [[air speed]].

R.O.B. also possesses a strong air game, thanks to all but one of his aerials having disjointed [[hitbox]]es, alongside a capable grab game. Despite being a [[Weight|heavyweight]], R.O.B.'s overall mobility is also respectable. Notably, R.O.B.'s once poor KO potential has been significantly improved, thanks to receiving a number of strong KOing options.

However, R.O.B.'s ground game lacks range compared to his air game. This is most obvious with his arm-based attacks, especially in regard to his overall grab range, which is now the shortest ranged in the game. While it is still strong, R.O.B.'s zoning game has also been somewhat toned down, as Robo Beam is slower and Gyro deals significantly less damage. R.O.B. is also susceptible to combos because of his heavy weight and large hurtbox. Lastly, his newfound KOing options are hindered by noticeable amounts of start-up lag.

Overall, R.O.B. is a more powerful character compared to the previous game, thanks to him largely retaining his strengths and having noticeably improved KO potential; yet, the larger competition present and many of the tools the new characters possess harm R.O.B more than they did in Brawl, thus resulting in his lower tier position relative to the cast. As such, he has achieved overall average tournament results, and has gained a number of dedicated players to his credit.

R.O.B. is the tenth [[weight|heaviest]] character in the game, yet he possesses respectable overall mobility in spite of his weight class. This is thanks to his average [[walk]]ing and [[dash]]ing speeds; above-average [[Air speed|air]], [[Falling speed|falling]], and [[fast fall]]ing speeds; slow [[air acceleration]]; high [[traction]], [[jump]] and [[double jump]]; and low [[gravity]]. Altogether, these attributes allow R.O.B. to outmaneuver some of his fellow heavyweights; make him almost as mobile as a middleweight; and grant him better jumping prowess than most characters of either weight class.

Like in ''Brawl'', R.O.B. is a zoning-oriented character with very useful projectiles to keep his opponents at bay. [[Robo Beam]] enables him to attack from considerable distance, and becomes the noticeably stronger Super Robo Beam when it is left idle for 14.3 seconds. While Robo Beam interrupts opponents faster, Super Robo Beam deals more damage and has higher knockback growth. [[Gyro]] is an auto-[[charge]]able projectile that becomes an [[item]] when fired. Compared to Robo Beam, it has a more favorable angle for disrupting opponents, while also being more manipulable as a projectile and having greater KOing potential. Thanks to R.O.B.'s [[item throw]]s being among the strongest in the game, Gyro is also very useful when [[Item throw#Directions and strength|smash thrown]] as an item.

Aside from his offensive prowess with projectiles, R.O.B. also does not have issues against projectiles, courtesy of [[Arm Rotor]]'s ability to [[reflect]] them with greater strength than they initially had. In addition to its reflection ability, Arm Rotor now boasts KO potential, thanks to its finishing hit having significantly higher knockback growth.

R.O.B.'s air game is also strong, thanks to the excellent and disjointed ranges of all but one of his aerials. Neutral aerial has large, disjointed hitboxes that make it a reliable combo starter at low to medium percentages when [[SHFF]]'d, as well as a useful spacing option. Up aerial is one of R.O.B.'s best moves overall, thanks to its usefulness in harassing airborne opponents by either juggling or KOing them. Back and down aerials are R.O.B.'s most damaging aerials when sweetspotted, and have large hitboxes like neutral aerial. However, they also boast specific strengths: the former has recovery potential thanks to it propelling R.O.B. forward slightly, whereas the latter is a [[meteor smash]]. Lastly, forward aerial is arguably R.O.B.'s least useful aerial because of its hitbox having much shorter range and not being disjointed. However, it is R.O.B.'s fastest aerial, which makes it reliable for spacing, especially when SHFF'd, as well as edge-guarding.

Unlike in ''Brawl'', R.O.B. now boasts respectable KO potential. Like his up aerial, back aerial, up throw and Arm Rotor, R.O.B.'s smash attacks now boast KO potential, thanks to being buffed in various ways. Forward smash's sweetspot deals slightly more damage and higher knockback. Although forward smash's other hitboxes deal less damage, they have been re-positioned farther outward, which improves its range. Up smash's sweetspot and down smash also deal more damage and, like forward smash, have had their hitboxes tweaked for the better: up smash now has hitboxes on R.O.B.'s arms that launch the opponent into its thruster hitboxes, whereas down smash is now a [[semi-spike]].

R.O.B.'s grab game has also improved. Forward and back throws are still limited in regard to utility, but are nevertheless decent for spacing and setting up edge-guards. In comparison, R.O.B.'s up and down throws are much more useful. Up throw is his most damaging throw; a viable KOing option, especially when boosted by [[rage]]; and can even be used for combos at low percentages. In comparison, down throw deals respectable damage, and is a reliable combo starter into his up aerial from 0% to medium percentages.

Although R.O.B. possesses a number of useful traits, he also has some noteworthy shortcomings. Despite his KO potential's drastic improvements, landing his KOing options can still be problematic because of them being laggy and/or having unimpressive ranges. The latter trait is particularly noticeable in regard to R.O.B.'s arm-based attacks, most of which have hitboxes that have either become smaller and/or tweaked for the worse. For example, his grab game is hindered by his overall grab range now being the shortest in the game because of his much smaller grabboxes, whereas his up tilt has drastically less utility because of its adjusted hitboxes.

In addition to R.O.B.'s hitbox issues, his hurtbox also hinders him, as it has become larger since ''Brawl''. When coupled with his faster falling speed, he is much more susceptible to combo-oriented characters, such as {{SSB4|Luigi}} and {{SSB4|Zero Suit Samus}}. This is further compounded by his aerials' inability to reliably break combos: neutral and down aerials are too slow, forward and up aerials only hit in front of and above R.O.B., respectively, and back aerial has both slow start-up and only hits behind him.

While R.O.B.'s zoning game remains his greatest strength, the universal nerf to projectile camping has somewhat toned it down. Gyro, in particular, has been the most adversely affected of his projectiles: in addition to retaining its susceptibility to being stolen, a fired Gyro deals drastically less damage and covers less range. The removal of [[glide toss]]ing also significantly hinders its approach potential. Robo Beam's nerfs are not as severe in comparison, but are nevertheless noticeable: it now deals slightly less damage, and both it and Super Robo Beam travel slower. As a a result of these nerfs, R.O.B. now has a more difficult time dealing with most characters that have better projectiles (such as {{SSB4|Sheik}} and {{SSB4|Diddy Kong}}); attacks that counteract his own projectiles (such as {{SSB4|Fox}} and {{SSB4|Falco}}); or both (such as {{SSB4|Villager}}).

R.O.B.'s [[Character customization|custom moves]] can alleviate many of his weaknesses. Wide Angle Beam, true to its name, can be aimed in a much wider arc, which enables R.O.B. to catch aerial opponents easily. However, it deals slightly less damage. Infinite Robo Beam, also true to its name, can be shot infinitely. This allows R.O.B. to use his zoning game constantly and defend himself. However, it also deals less damage, cannot ricochet, and Super Robo Beam needs to charge for longer. Reflector Arm acts like a traditional reflector, having a higher reflection multiplier and longer duration. However, R.O.B. will not move when using it, preventing him from pressuring the opponent.

Overall, R.O.B. is a defensive character that still possesses a strong zoning game, but now wields improved close-range offense. While R.O.B. now has to use close quarters combat more frequently because of his playstyle now being less reliant on his projectiles, he can now effectively KO opponents without having to rack up an outstanding amount of damage. As a result, he has become a more potent character than he was in ''Brawl'' and has some dedicated and noteworthy mains to his credit, such as {{Sm|Holy}}, {{Sm|Mister Eric}}, and {{Sm|8BitMan}}.

R.O.B. has received a mixture of [[buff]]s and [[nerf]]s in the transition from ''Brawl'' to ''Smash 4'' but was noticeably nerfed overall. The most prominent buff was to his KO potential; many of his KO options in ''Brawl'' have become more powerful and/or slightly easier to land, while other moves have been strengthened to the point of possessing reasonable KO potential, such as his up aerial and down smash. R.O.B. has also seen some benefits from the changes to ''Smash 4''{{'}}s mechanics as the weakening of [[SDI]] improves the reliability of his multi-hit moves and the changes to hitstun canceling and DI have improved his combo potential. R.O.B. also benefits from the introduction of [[rage]] as it further improves his KO power and his solid recovery and heavy weight allow him to build up a high amount of rage. R.O.B.'s mobility has also improved significantly, especially in the air, sporting higher walking speed, dashing speed, air speed, falling speed, air acceleration, and gravity. In particular, the latter four are all above average now, with the latter three no longer being among the lowest in the game, which makes him much more resilient.

However, R.O.B. also received some significant nerfs. His powerful zoning game has been hampered as his projectiles have seen some noticeable downgrades. [[Robo Beam]] travels significantly slower while [[Gyro]] is much weaker when fully charged and its firing rate is slower. R.O.B. was also one of the characters who was hindered the most by the removal of [[glide toss]]ing as it significantly hinders his approach with Gyros. This makes approaching more important, as R.O.B.'s camping and defensive game was significantly toned down. R.O.B. is a larger target and a fair amount of his moves have reduced range making him an even easier target to hit. Further compounding this is his increased falling speed and gravity, as while it does make him a lot more resilient and makes it drastically easier for him to land, it gives him a high susceptibility to combos, especially considering the changes to hitstun canceling. R.O.B.'s overall frame data has been nerfed as many of his attacks have increased startup lag, shorter durations, increased ending lag or all three. R.O.B.'s aerial game has also been toned down. R.O.B.'s short hop is also significantly lower which greatly reduces his aerial output and his forward and back aerials have increased landing lag with the later also having a much worse auto-cancel window now, as well as his up and down aerials. While R.O.B. has much greater KO power, his existing KO moves have seen some downgrades, making them harder to land, as many of them are noticeably laggier and some of them, mainly forward smash and back aerial, now have significantly weaker sourspots. Neutral aerial is weaker in exchange for having more combo potential, forward aerial is weaker and has increased ending lag, back aerial is drastically laggier and possesses many new sourspots, up aerial deals much less damage (although it connects more reliably and the final hit is stronger) and down aerial is weaker. His recovery was also slightly nerfed overall, as while his air speed and air acceleration are drastically faster, [[Robo Burner]] travels slower and covers less distance while his aforementioned increased falling speed and slower back aerial further hinder his recovery.

Overall, while R.O.B.'s KO power is greater, it does not make up for his worse zoning game combined with his worse frame data, aerial game and recovery. R.O.B. is largely forced to engage in a mix of zoning and close quarters combat in order to score KOs and his worse frame data, reduced range on multiple moves, larger size and increased susceptibility to combos do not help this matter. The changes to ''Smash 4''{{'}}s mechanics also do not benefit him as much as some other characters as the changes to hitstun canceling is very much a double edged sword for him and he has seen some notably hindrances mainly from the removal of glide tossing. R.O.B. does not even benefit from having a better matchup spread as while he has an easier time against some of the characters who gave him a difficult time in ''Brawl'' such as {{SSB4|Meta Knight}}, {{SSB4|King Dedede}}, {{SSB4|Falco}} and {{SSB4|Olimar}} due to their severe nerfs, this cannot be said for the entire cast and he has a very difficult time against {{SSB4|Cloud}}, and {{SSB4|Bayonetta}}. As a result, R.O.B. is considerably worse than in ''Brawl''.

*{{change|R.O.B.'s design has slightly changed. His body now has a satin finish, instead of a [[wikipedia:Polishing (metalworking)|polished]] finish; his gray-colored components are darker; his head is slightly smaller; and his eyes are slightly larger and have more defined lenses. Altogether, these changes make R.O.B. appear significantly more in line with his appearance as a real life video game peripheral.}}

*{{change|R.O.B.'s default costume now changes depending on the language the game is set to. The Famicom color scheme (which was R.O.B.’s default costume in ''Brawl'') is still the default in the Japanese, Chinese, or Korean versions. All other versions use his NES colors as the default instead. The non-default color scheme appears as the second costume in both cases.}}

*{{change|R.O.B. now faces the foreground at an angle instead of facing directly forward. He also always faces the screen, regardless of whether he’s facing left or right.}}

*{{change|R.O.B. is more expressive. He appears angry while charging his up and down smash attacks, and during his up and down throws and [[Arm Rotor]]. R.O.B. also appears sad when he is [[grab]]bed.}}

*{{bugfix|{{GameIcon|ssb4-u}}R.O.B. does not emote whatsoever in [[Versus Mode]]. However, he emotes properly in single-player modes, such as [[Training Mode]].}}

*{{nerf|R.O.B. is larger. This makes his hurtbox larger. While this would also improve his overall [[range]], this is slightly mitigated by some of his moveset having smaller hitboxes.}}

*{{buff|R.O.B. [[dash]]es faster (1.5 → 1.568), although his dashing speed is slower relative to the cast.}}

*{{buff|R.O.B.'s [[air acceleration]] is drastically higher (0.046 → 0.085), going from the third slowest in the game to above average. This also improves his recovery, as his midair jump still halts all his horizontal momentum in the air.}}

*{{change|R.O.B. [[falling speed|falls]] significantly faster (1.2 → 1.6), with him receiving the second largest increase out of everyone, only behind {{SSB4|Lucario}}. Relative to the cast, his falling speed has gone from the 5th worst in the game to above average. As a result, he is no longer a [[falling speed|floaty]] character. This significantly improves his vertical endurance, but makes him much more susceptible to combos.}}

*{{change|R.O.B.'s [[gravity]] is noticeably higher (0.065 → 0.09), going from the 7th lowest in the game to above average. When combined with his significantly increased falling speed, this substantially improves his ground-to-air transitioning and leaves him much less susceptible to juggling, but it also makes him more susceptible to combos, which is further exacerbated by the changes to [[hitstun canceling]] and his larger hurtboxes.}}

*{{nerf|Rolls have a new animation where R.O.B. does not move as far into the Z axis allowing his opponents to punish his rolls sooner despite their longer duration.}}

*{{buff|Opponents gain much more height when [[footstool]]ing off of R.O.B., making him much less susceptible to footstool combos.}}

*{{change|The changes to [[hitstun canceling]] both help and hinder R.O.B. It significantly improves his own combo potential, but it also makes him more susceptible to combos, especially when combined with his significantly increased falling speed, higher gravity, and larger hurtboxes.}}

**{{nerf|Both hits of neutral attack have a shorter duration (frames 3-6 → 3-4) and smaller hitboxes as all of their hitboxes except for the main hitboxes have been removed and their size (3u → 3.5u) and x/y/z offset (-1/0/-7 (both) → 0/10/12.5 (hit 1), 0/7.7/13 (hit 2)) were not fully compensated. This also means that the first hit always launches vertically (100°/361° → 100°) removing the near hit's ability to [[lock]] opponents.}}

**{{nerf|Forward tilt has more ending lag (FAF 30 → 34) and tip forward tilt has a smaller hitbox.}}

**{{nerf|Down tilt has a smaller [[trip]] chance (40% → 20%).}}

**{{buff|Base forward smash deals 1% more damage (14% → 15%) and has increased knockback (30 (base), 95 (scaling) → 32/100), improving its KO potential. Forward smash also has a slightly larger hitbox, and its mid and tip hitboxes have been re-positioned farther outward. Altogether, these changes improve its range.}}

**{{change|Up smash's sweetspot is now placed on R.O.B.'s base while the sourspot is now the tip. This makes up smash a more powerful KO option against grounded opponents but hinders its use as an anti-air.}}

**{{buff|Up smash has a new initial hit which deals 3% and launch opponents at 111°. These changes significantly improve its reliability giving up smash less startup lag (frame 12 → 10), and grant it [[out of shield]] potential.}}

**{{nerf|Up smash has less knockback scaling (100 → 98) hindering its KO potential. It also has a smaller hitbox.}}

**{{nerf|Up smash's main hit has increased start-up lag (frame 12 → 14) and up smash has increased ending lag (FAF 44 → 49). The removal of [[DACUS]] also slightly hinders up smash's approach potential.}}

**{{buff|Down smash's final hit deals more knockback (90 (base), 105 (scaling) → 37/160) significantly improving its KO potential. Down smash also has larger hitboxes.}}

**{{nerf|Down smash has increased startup (frame 4 → 7) and ending lag (FAF 35 → 46). The multi-hits also no longer deal consistent damage (2% → 2%/1.5%)}}

**{{change|Neutral aerial deals 2% less damage (10% → 8% (base)/6% (tip)) and has decreased knockback scaling (108 → 100 (base)/98 (tip)). When coupled with the changes to hitstun canceling, these changes grant and improve its combo potential. However, these changes significantly hinder its damage racking KO potential.}}

**{{nerf|Forward aerial deals less damage (10% (clean)/6% (late) → 7%). While this improves its [[wall of pain]] potential at higher percents combined with R.O.B.'s higher air speed, it significantly hinders its safety at lower percents and its KO potential. It also has a smaller hitbox, a shorter duration due to the removal of the late hit (frames 7-17 → 6-7), more ending lag (FAF 32 → 36) and more landing lag (12 frames → 15). Its higher ending lag combined with R.O.B.'s lower short hop prevents R.O.B. from performing another aerial after it in a short hop.}}

**{{buff|Clean back aerial has more base knockback compared to the previous hitbox (30 → 32) improving the clean base's KO potential.}}

**{{buff|Back aerial's hitboxes are positioned farther outward, improving its range. It also propels R.O.B. slightly farther, improving its recovery potential (although this is nullified by back aerial's increased lag).}}

**{{nerf|Due to consisting of sweetspots and sourspots instead of a consistent hitbox, back aerial no longer deals consistent damage (11% → 12% (clean base)/10% (clean tip)/6% (late base)/4.5% (late tip)). While the clean base is stronger, all other hitboxes are weaker making back aerial a much more difficult aerial to utilize.}}

**{{nerf|Back aerial has more startup lag with a shorter duration (frames 11-25 → 19-23 (clean)/24-29 (late)); ending lag (FAF 40 → 53); and landing lag (12 frames → 22) which is further exacerbated by its worse [[auto-cancel]] window (frame 26 → 46).}}

**{{buff|The weakening of SDI makes up aerial significantly more difficult to escape from.}}

**{{nerf|Down aerial auto-cancels later (frame 27 → 45) significantly hindering its use as a landing and spacing tool.}}

*{{nerf|All grabs have significantly smaller grabboxes with R.O.B. now having the worst grab range in the game.}}

*{{nerf|Standing and pivot grabs have increased start-up lag (frame 6 → 7 (standing), frame 10 → 11 (pivot)).}}

**{{buff|Up throw deals 2% more damage (10% → 12%) although its knockback was compensated (70 (base), 72 (scaling) → 60/70).}}

**{{buff|Arm Rotor now has a finishing hit, making it less punishable. The final hit has increased knockback (40/50 (base), 120 (scaling) → 40/210).}}

**{{buff|Arm Rotor now covers significantly more distance when moved forward or backward, improving its approach potential and safety.}}

Like {{SSB4|Mario}} and {{SSB4|Pit}}, R.O.B. has received a very small number of direct changes from game updates. Update [[1.0.4]]'s changes to [[LSI]] indirectly buffed him by enabling his [[Beep Boop]] [[combo]] ({{mvsub|R.O.B.|SSB4|down throw}} → {{mvsub|R.O.B.|SSB4|up aerial}}) to function past low percentages, and become one of the game's most infamous [[50/50]] [[KO combo]]s out of [[grab]]. However, update [[1.0.6]] notably decreased the [[knockback]] of R.O.B.'s {{mvsub|R.O.B.|SSB4|up throw}}, with it now [[KO]]ing roughly 15-20% later; previously, it was the strongest up throw in the game, and the second strongest [[throw]] of any kind after {{SSB4|Ness}}' {{mvsub|Ness|SSB4|back throw}}.

Despite this, up throw remains a powerful KOing option and one of the best KO throws, especially on [[stage]]s with [[platform]]s. Its lower base knockback also granted it combo potential at low percentages; when coupled with its lower base knockback and launch [[angle]], its combos are more varied compared to down throw's (which can mainly just combo into uair regardless of percent), such as being able to combo into {{mvsub|R.O.B.|SSB4|up smash}} and {{mvsub|R.O.B.|SSB4|forward aerial}}, which can additionally more easily lead into farther followups. As a result, up throw can now be used to perform more damaging combos at low percents compared to what down throw can do, while additionally conserving the [[fresh]]ness of both down throw and up aerial for more powerful Beep Boops later on.

Update [[1.1.1]]'s increase to [[shieldstun]] indirectly nerfed R.O.B.; in addition to making his relative [[shield]] safety among the cast less impressive because of his moves having low [[damage]] output or being [[projectile]]s (and thus saw less increase to their shieldstun than most other characters' moves), getting grabs that he was heavily dependent on to KO became remarkably more difficult, especially with his already terrible grab [[range]] that made [[shield grab]]bing difficult even before the shieldstun patch. Lastly, update [[1.1.4]] marginally increased the size of R.O.B.'s [[hurtbox]]es and decreased his [[tripping]] stance's [[invincibility]] [[frame]]s by standardizing it, though these had a negligible impact on his viability.

|neutralname=&nbsp;

|ftiltname=&nbsp;

|utiltname=&nbsp;

|dtiltname=&nbsp;

|dtiltdesc=Thrusts his arms at a low angle. It hits on frame 3, which ties it with neutral attack as R.O.B.'s fastest attack. Although it has a small chance to [[trip]] opponents, its overall fast speed largely offsets this and makes it an excellent set-up option.

|dashname=&nbsp;

|usmashname=&nbsp;

|usmashdesc=Performs a handstand and activates his thrusters to emit a [[Flame|fiery]] blast upward. It hits on frame 10, which is somewhat fast for a smash attack. It also has deceptive horizontal range on the ground, thanks to R.O.B.'s arms having hitboxes that launch opponents into the thrusters' hitboxes, the latter of which are fairly powerful. Its base KOs middleweights at 113%, whereas its tip KOs them at 116%. Altogether, these traits make it a reliable KOing option, especially from [[out of shield]] because of R.O.B.'s high traction. However, it has high ending lag.

|dsmashname=&nbsp;

|dsmashdesc=Lowers his torso and spins it around rapidly while outstretching his arms to perform a series of [[Wikipedia:Professional wrestling attacks#Clothesline|discus clotheslines]], similarly to [[Arm Rotor]]. It hits on frame 7, which is very fast for a smash attack. Thanks to it being a [[semi-spike]] and its last hit's very high knockback growth, it KOs at middleweights at 129% while near the edge, and is very effective for edge-guarding. However, its base hitboxes launch the opponent behind R.O.B., which means that he must face away from the edge when attempting to use this move in order to properly launch the opponent off-stage. Like forward and up smash, it also has high ending lag.

|nairname=&nbsp;

|nairdesc=Activates his thrusters to somersault and emit a fiery blast in a circular motion. Its large hitbox, very minimal landing lag and ability to auto-cancel with a short hop collectively make it very useful for spacing, approaching and starting combos. Due to it hitting on frame 18, however, it is punishable if it is not spaced properly.

|fairname=&nbsp;

|fairdesc=A double forearm club. It hits on frame 6, making it R.O.B.'s fastest aerial. It is also ideal for spacing when [[SHFF]]'d, has minimal landing lag and is decent for edge-guarding. However, it lacks KO potential because of its average damage output and very low base knockback. It is also R.O.B.'s only aerial that does not have a disjointed hitbox.

|bairname=&nbsp;

|bairdesc=Leans forward and activates his thrusters to emit a fiery blast behind himself. Its clean base hitbox is strong enough to KO middleweights at 126% while near the edge, thanks to its respectable damage output and very high knockback growth. Back aerial can also be used for horizontal recovery, as it slightly propels him forward and does not consume [[Robo Burner]]'s fuel. It can autocancel in a short hop due to it altering R.O.B's momentum but due to it hitting on frame 19 and having high ending lag and 22 frames of landing lag, it is very slow and punishable if it is not spaced properly and auto-canceled.

|uairname=&nbsp;

|uairdesc=Rapidly rotates his arms upward. It hits on frame 7, making it R.O.B.'s second fastest aerial. It is down throw's most reliable follow-up from low to medium percentages. It is also useful for juggling and KOing, as its loop hits keep the opponent trapped reliably, whereas its last hit's extremely high knockback growth enables it to KO middleweights at 115% while near the upper [[blast line]]. It can also auto-cancel with a short hop. However, it has 22 frames of landing lag like back aerial, which makes it punishable if it is not auto-canceled.

|dairname=&nbsp;

|dairdesc=Activates his thrusters to emit a fiery blast downward. The middle portion of the blast is a powerful [[meteor smash]], which makes it a very potent edge-guarding option, especially after an [[Edge-guarding#Ledge trump|edge trump]] if the opponent re-grabs the edge. It briefly stalls R.O.B's momentum, allowing it to autovancel in a short hop. Due to it hitting on frame 20 and having 43 frames of ending lag, it is R.O.B.'s slowest aerial. When coupled with its 21 frames of landing lag, it is punishable if it is not spaced properly and auto-canceled.

|grabname=&nbsp;

|grabdesc=[[wikipedia:Clinch fighting|Clinches]] the opponent. Due to his grabboxes being significantly smaller than in ''Brawl'', R.O.B.'s overall grab range is the shortest in the game.

|pummelname=&nbsp;

|pummeldesc=Squeezes the opponent. A fairly fast pummel.

|fthrowname=&nbsp;

|fthrowdesc=Shoves the opponent away. It can be used to set up an edge-guard.

|bthrowname=&nbsp;

|bthrowdesc=Flings the opponent away. Like his forward throw, it can be used to set up an edge-guard.

|uthrowname=&nbsp;

|uthrowdesc=A [[Wikipedia:Piledriver (professional wrestling)#Reverse piledriver|jumping reverse piledriver]]. R.O.B.'s strongest throw and, prior to update [[1.0.6]], it was the strongest up throw in the game, as it was capable of KOing under 150%. As of update 1.0.6, it now KOs middleweights at 174%, although [[platform]]s assist its KO potential considerably: it KOs middleweights at 160% when used on {{SSB4|Battlefield}}'s low platforms, and KOs them at 145% when used on Battlefield's top platform. Although rare, R.O.B. can also use up throw for a [[suicide KO]] if it is performed on a moving platform, as he will continue performing the throw all the way to the lower blast line if there is no platform to stop his descent. In addition to its KO potential, it has combo potential thanks to it launching at 80°, with its follow-ups being upward angled forward smash, dashing up smash, forward aerial, and up aerial from 0%-40%. However, its smash attack combos are most reliable against heavyweights and fast-fallers.

|dthrowname=&nbsp;

|dthrowdesc=Drills the opponent into the ground headfirst. It has very high base knockback, very low knockback growth and launches at 88°, which collectively enable it to combo into neutral and up aerials at low to medium percentages. The latter combo has been nicknamed the "Beep Boop" and can even function as a KO set-up at high percentages if R.O.B. can properly read the opponent's reaction. However, its neutral aerial combo is only reliable beginning at 0%, whereas the "Beep Boop" can be avoided if the opponent DIs horizontally after being thrown.

|floortdesc=Spins his torso around to throw a low-angle hook around himself while getting up.

|nsdefdesc=An optical laser. When uncharged, it is a very small energy blast instead of a laser, and can only damage opponents at point-blank range. However, it can be fired consecutively and has deceptively high knockback growth, which allow it to ward off nearby opponents. Conversely, both Robo Beam and Super Robo Beam can damage opponents from afar and ricochet, but cannot be fired consecutively. Robo Beam and Super Robo Beam also deal noticeably more damage when fired at point-blank range. It is one of R.O.B.'s options for zoning alongside Gyro, with Robo Beam being better for his neutral game, while Super Robo Beam is better for surprising opponents. It and all of its custom variations have [[transcendent priority]]. Uncharged Robo Beam becomes Robo Beam after being left idle for 2.6 seconds (160 frames), and Robo Beam becomes Super Robo Beam after being left idle for 14.3 seconds (860 frames).

|nsc1desc=R.O.B. can aim on a much wider arc, but at the cost of Robo Beam and Super Robo Beam having slightly lower damage outputs. Fully charged shots are much quicker and stretch across the screen.

|nsc2desc=Robo Beam can be fired consecutively, but at the cost of a lower damage output, shorter range and its ability to ricochet. These drawbacks also apply to Super Robo Beam, which also takes longer to charge.

|ssdefdesc=Rapidly spins his torso around to perform a series of discus clotheslines that concludes with an uppercut. Mashing the special button extends the duration of the move. Propels R.O.B forward slightly and hovers somewhat in mid-air. Unlike in ''Brawl'', it can trap opponents reliably and its last hit has KO potential, thanks to its extremely high knockback growth enabling it to KO middleweights at 147% while near the edge. It can also [[reflect]] projectiles with 50% more power than they originally had, and move R.O.B. forward or backward while the [[control stick]]/circle pad is tilted in the respective direction. It and all of its custom variations have transcendent priority.

|ssc1desc=Quicker, stronger, and reflects projectiles with 80% more power than they originally had, but immobilizes R.O.B, and the hits knock opponents away instead of trapping them.

|ssc2desc=Deals more damage and moves R.O.B. backward while it is being performed, making it better suited for defense, but at the cost of having a significantly shorter duration overall.

|usdefdesc=Activates his thrusters in order to fly. It grants impressive vertical and horizontal recovery distance, although R.O.B. has a set amount of fuel to use in order to perform this move. Fuel is recovered over time as long as R.O.B. is grounded. Tilting the control stick up repeatedly instead of holding the special button while flying can conserve fuel better and allow R.O.B to travel farther. It is one of the very few up specials to not cause [[helpless]]ness, as it can be canceled any time by executing an aerial attack, after which R.O.B can reactivate it or use other moves. Otherwise, R.O.B. cannot use other specials, [[fast fall]], or [[air dodge]] while using the Burner. R.O.B. is also immune to [[footstool jump]]s while using this move, although other characters can still jump off of him regardless. It also grants [[intangibility]] on frames 2-4, but only when performed on the ground.

|usc1desc=Functions like a traditional recovery move, as R.O.B. simply ascends quickly and gains a small hitbox. It grants outstanding vertical recovery after a jump; does not cause helplessness; can be followed up with any aerial; and can meteor smash if it hits the opponent precisely. However, it grants very minimal horizontal recovery distance. Like Robo Burner, R.O.B must use an aerial attack in order to fast fall, air dodge, or use his other specials as follow-ups. Additionally, its meteor smash has below-average power.

|usc2desc=Grants faster movement speed, but at the cost of consuming more fuel.

|dsdefdesc=Charges a spinning top on his base. R.O.B.'s other zoning option alongside Robo Beam, it can be picked up and thrown as an [[item]] after making contact with either the opponent or the stage. However, opponents can do the same and thus use the top against him. Gyro takes 1.5 seconds (90 frames) to fully charge. Only one Gyro can be active at a time, and attempting another will result in R.O.B. flailing in confusion. It lasts longer when launched with the special button, but once picked up and thrown, it dissipates almost immediately. Typically, Gyro deals little knockback when touched, albeit enough to harass anyone trying to get past. In comparison, it will somewhat launch opponents a short distance toward R.O.B. after being thrown and making contact with the ground again. This enables it to partake in combos if R.O.B. is able to time his attacks and predict his opponent's movements. Due to being an item, however, it can also be grabbed by an opponent and thus used against R.O.B.

|dsc1desc=The top is a flame and deals more damage, but at the cost of covering less distance and having increased ending lag.

|fsdesc=Re-configures his body into a cannon-like form in order to fire a large laser that fans out into smaller lasers. These lasers trap the opponent and deal damage, before [[paralyze|paralyzing]] trapped victims and ending with a large energy blast. It is excellent for damage racking and can be angled, similarly to {{b|Zero Laser|Samus}}. Its blast is also quite powerful, as it KOs middleweights at 70% while near the edge.

|desc-up=Faces the screen and then spins his head and torso in a circle.

|desc-side=Faces the screen and sways his head around while emitting flashing sparkles from his eyes.

|desc-down=Faces the screen and moves his torso down to his base before spinning it back up into place.}}

|victory-desc=A remix of ''{{s|wikipedia|Stack-Up}}''{{'}}s memory mode title screen jingle.

|desc-1=Uses [[Robo Burner]], spins and then lands, after which his torso lowers and slowly elevates back into place while spinning his head.

|desc-2=Rears back his arms, then rotates them into an upward position while spinning his head, after which he performs a cheering gesture while continuing to spin his head.

Thanks to his potent zoning and grab games, R.O.B. was initially considered a high-tier character during ''SSB4''{{'}}s release, similarly to initial perceptions of him during the early days of ''Brawl''{{'}}s metagame. However, after update [[1.0.6]] nerfed his up throw's power, his reputation declined to the point that he was perceived as a mid-tier character. Nevertheless, R.O.B.'s representation in competitive play remained decent, while he continued to enjoy decent placements thanks to mains such as {{Sm|8BitMan}}, {{Sm|OCEAN}}, and {{Sm|Raffi-X}}. This resulted in him being ranked 20th on the first [[tier list]].

However, other characters like {{SSB4|Donkey Kong}}, {{SSB4|Lucario}} and, most notably, {{SSB4|Toon Link}}, have achieved much stronger results than R.O.B. To further compound this, R.O.B. has become rarer in competitive play due to having unfavorable matchups against all but [[Roy (SSB4)|one]] of the DLC characters. This decline in popularity and results would end up with R.O.B. being ranked 28th on the second tier list. Without significant breakthroughs against his unfavorable matchups, as well as further notable changes towards his zoning capabilities, he continued to languish from the addition of the DLC characters and waning perception. All of this led to him falling to 33rd on the third tier list (this drop is notable for being the third highest between the second and third tier lists). While other top-tier characters continued to have their competitive prospects developed, R.O.B. players have failed to propel his competitive prospects further, leaving his issues towards a large susceptibility to combos and difficulty in landing KO moves exacerbated further. As with the previous drop, he continued to fall behind in the metagame. Thus, this relegates him to 35th on the fourth tier list.

*{{Sm|8BitMan|USA}} - One of the best R.O.B. players in the world. Placed 4th at {{Trn|Glitch 2}}, 9th at the {{Trn|The Big House 8}}, and 17th at {{Trn|CEO 2015}}, {{Trn|EVO 2015}}, and {{Trn|The Big House 6}} with wins over players such as {{Sm|Fatality}}, {{Sm|Samsora}}, and {{Sm|Salem}}. Ranked 8th on the [[South Florida Power Rankings]].
