'''R.O.B.''' ({{ja|ロボット|Robotto}}, ''Robot'') is a playable character in ''[[Super Smash Bros. Ultimate]]''. He was officially revealed on [https://www.youtube.com/watch?v=L93H7YC-83o June 12th, 2018] alongside {{SSBU|Dr. Mario}}, {{SSBU|Duck Hunt}}, and the rest of the returning roster. R.O.B. is classified as [[Fighter number|Fighter #42]].

R.O.B.'s beeping sound effects from ''Brawl'' and ''Smash 4'' were repurposed for ''Ultimate''.

==How to unlock==
Complete one of the following:
*Play [[VS. match]]es, with R.O.B. being the 31st character to be unlocked.
*Clear {{SSBU|Classic Mode}} with {{SSBU|Pikachu}} or any character in its unlock tree, being the 3rd character unlocked after {{SSBU|Shulk}}.
*Have R.O.B. join the player's party in [[World of Light]].
R.O.B. must then be defeated on [[Wrecking Crew]] (the [[Ω form]] is used in World of Light).

==Attributes==
R.O.B. is the [[Weight|eighteenth heaviest]] character in the game, being tied with {{SSBU|Snake}} and {{SSBU|Banjo & Kazooie}}, thus making him a heavyweight. R.O.B. sports an above average [[Walk|walking speed]], [[initial dash]], and [[falling speed]], is tied with {{SSBU|Ike}} and {{SSBU|Bowser Jr.}} for the 26th fastest [[air speed]], average [[Dash|dashing speed]], [[gravity]], and [[traction]], as well as the 30th highest [[air acceleration]]. This grants him mobility that is fairly average overall, yet balanced compared to most of his fellow heavyweights. This, along with several of his other attributes, most notably his extremely long-distanced recovery, noticeably set him apart from most of them.

Like in ''Brawl'' and ''Smash 4'', 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 kill power. 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 projectiles, R.O.B's ground game is also excellent. Jab comes out on frame 3 and acts as a quick move at low percentages to escape pressure situations, and it can also jab lock and combo. Forward tilt can be useful for spacing at higher percentages since it comes out on frame 7, but its usefulness ends there. Up tilt comes out on frame 4, and is very good for acting as an anti air and combos into his up air. Down tilt is R.O.B.'s single best move, as it lowers his hurtbox, has great range, is tied with jab as his fastest move at frame 3, pressures shields, trades with shield grabs, and its total active frames is only 14, meaning it is one of the safest pressuring moves in the game. It also combos into itself at lower percentages, and at higher percents it can combo into grab or dash attack, and can send opponents into a jab lock scenario for a KO at relatively low percentages. Lastly, dash attack is useful for punishing landings and whiffs, is very fast at frame 7, has decently long range, and can combo into his forward air at low to mid percentages.

R.O.B.'s air game is also great, thanks to the excellent and disjointed ranges of all but one of his aerials. Neutral aerial has large, disjointed hitboxes that make it great for covering the opponents options if they lack the range to deal with it. It's also very hard to punish out of shield, due to its damage, total landing lag (7 frames) and range. It is also a reliable combo starter at low to medium percentages when [[SHFF]]'d, as well as a useful spacing option and, to a lesser extent, a kill move. Up aerial is a great vertical kill move due to its large and long-lasting hitboxes, fast startup, and the last hit’s high knockback. Back and down aerials are R.O.B.'s most damaging aerials when sweetspotted, and they too have large hitboxes, much like neutral aerial. However, they also boast their own specific strengths. Back air has recovery potential thanks to it propelling R.O.B. forward, and it's his only aerial that can KO in neutral due to its very high knockback and huge hitbox. Not only that, but it is also one of the strongest back aerials in the game. Down air is a [[meteor smash]] that can hit below the ledge and KO very early if done so. It is also active for 6 whole frames, making it difficult to avoid for characters with linear recoveries. Lastly, forward aerial is R.O.B.'s fastest aerial coming out on frame 6, making it very spammable in neutral due to how low committal it is to use, as it is safe on shield. However, its hitbox has much shorter range and isn't disjointed.

R.O.B.'s grab game also has its uses. Forward and back throws are decent for spacing and setting up edge-guards. Back throw can also KO at the ledge at very high percents, and both can combo into dash attack or gyro at very low percents. In comparison, R.O.B.'s up throw is much more useful. It is his most damaging throw, a solid kill move (especially when boosted by [[rage]] or if he lands on a platform), and can even be used for combos at low percentages. His down throw, despite not being a kill move, is also one of his best tools for taking a stock. While it deals poor damage, it buries opponents, allowing for followups into up tilt, up air, or even up smash. However, with mashing, the opponent can typically get out before R.O.B. has any chance to act. As such, it is more of a read-based tool rather than a guaranteed method for taking a stock.

Although R.O.B. possesses a large number of strengths, he does also have a few noteworthy shortcomings. Despite having a good chunk of moves with respectable KO potential, landing his kill moves can be problematic because of them either being laggy or having unimpressive ranges, or possibly even both. The latter trait is particularly noticeable in regard to R.O.B.'s arm-based attacks, most of which have short ranges. His grab game is also hindered by his overall grab range being the shortest in the game.

In addition to R.O.B.'s hitbox issues, his hurtbox also hinders him, as it is very large and wide, meaning he can get hit by a lot of combos that other characters such as {{SSBU|Jigglypuff}} would have an easier time getting away from. This also means that he has difficulty dealing with combo-oriented characters, such as {{SSBU|Pikachu}} and {{SSBU|Mario}}. This is further compounded by his above average falling speed, as well as his aerials' inability to reliably break combos: neutral and down aerials are very slow in terms of startup, forward and up aerials only hit in front of and above R.O.B., respectively, and back aerial is a mix of both: it has slow startup and only hits behind him.

Overall, R.O.B. is a non-traditional heavyweight zoner. His decently fast mobility and overall above average frame data allow him to easily pressure unwary opponents, and he doesn’t have too much trouble killing if he can get the advantage. While his overall range is rather small for a zoner like him, it is functional in the long run regardless. However, R.O.B. players must be very cautious, as a single combo can be all it takes to get R.O.B. in an uncomfortable position or possibly even kill him, thanks to his large size, moderately high weight, above average falling speed, and lack of options to break free from combos.

==Changes from ''[[Super Smash Bros. 4]]''==
R.O.B. has been significantly buffed overall in his transition to ''Ultimate''. Similarly to {{SSBU|Mario}}, R.O.B. has received comparatively few major changes in his transition from the previous game; however, most of these changes have majorly improved his toolkit, and he benefits from the changes made to the game's engine as well.

Arguably R.O.B.'s most impactful buff is to his Arm Rotor move. Previously universally regarded as one of the worst attacks in ''Smash 4'', it executes faster, with reduced startup lag, much less ending lag, and larger hitboxes with improved angles that connect with each other much better. This not only significantly improves its use as an [[edgeguarding]] option, but when combined with the other changes made to his moveset, it has now become one of the most devastating combo finishers in ''Ultimate'', granting R.O.B. potential [[zero-to-death combo]]s and allowing him to KO opponents at absurdly early percentages.

Several of R.O.B.'s attacks have received quality of life changes that improve their utility. Forward smash and back aerial deal more knockback, granting them increased KO potential and toning down one of R.O.B.'s previous weaknesses. Up tilt has had its first hit's hitbox from ''Brawl'' restored, increasing its range and reliability. Down smash also launches opponents at a consistent angle, improving its consistency all around. Robo Beam has larger hitboxes and launches at lower angles, improving their effectiveness as edgeguarding options. Lastly, Gyro has been significantly buffed: it can now be returned to the dock once R.O.B. has grabbed it to charge it again and fire it with less startup, as opposed to tossing it once he has grabbed it. It can also now be jump canceled. These changes grant R.O.B. even more potential combo routes and give him more safe options against opponents.

R.O.B. also benefits from most of the universal changes to the game's engine. The universal increase in mobility and the ability to use any attack out of a run cancel allows him to close out the distance more effectively and compounds his improved up-close game. The universally increased shieldstun for grounded attacks has also been fairly beneficial to R.O.B., as it makes his very fast and decently-ranged down tilt safer on shield. The universal decrease to landing lag noticeably improves R.O.B.'s combo game as well; aside from changes made to his Arm Rotor, they make up aerial's looping hits more viable for starting combos, and neutral aerial's reduced start-up lag coupled with its decreased landing lag noticeably improves its combo potential and makes it a safer option when landing. Lastly, the changes to [[air dodge|air dodging]] benefit R.O.B., as they allow him to edgeguard his opponents more effectively and use a directional air dodge out of Robo Burner to gain more distance, improving his already excellent recovery.

However, R.O.B. has received a few nerfs as well. His [[grab]] game has been weakened overall, with universal changes to grabs hindering the safety of his grabs despite his improved standing grab. His [[up throw]] has increased endlag, making follow-ups harder, and his down throw now buries, allowing for read-based follow-ups at high percents, but removing any guaranteed set-ups at low to mid percents, particularly his effective down throw-up air combo, dubbed the "Beep Boop". R.O.B. also retains a few of the same issues from his previous appearance; his unusually large size and lack of fast aerial options leave him susceptible to [[juggling]] (with the buffs to his neutral air failing to fully address this issue), his up-close game is still exploitable due to R.O.B.'s lack of attacks with disjointed range, and his recovery remains predictable and easy to hit him out of with a sufficiently ranged move.

Overall, R.O.B.'s playstyle remains fundamentally unchanged from ''SSB4'', but changes to several of his attacks and to the game's engine have now properly cemented R.O.B. as the "jack-of-all-trades" between his fellow zoning brethren, as they give him having a far deadlier punish game compared to both of his previous appearances. R.O.B.'s results in the early metagame of ''Ultimate'' have been the strongest of any of his appearances thus far, thanks to the efforts of notable players such as {{sm|8BitMan}}, {{sm|Dill}}, {{sm|OCEAN}}, {{sm|Raffi-X}}, {{sm|WaDi}} and {{sm|Zackray}}. This has lead to a strikingly positive reception from the competitive Smash community, with most players viewing him as a high tier or even top tier character, in comparison to his mid tier status in both ''Brawl'' and ''SSB4''.

''For a gallery of R.O.B.'s hitboxes, see [[R.O.B. (SSBU)/Hitboxes|here]].''

{{MovesetTable
|game=SSBU
|neutralcount=2
|neutralname=11 / 12
|neutral1dmg=3%
|neutral2dmg=3%
|neutraldesc=Two alternating {{iw|wikipedia|hook|boxing}}s. Both of its hits hit on frame 3, which ties it with down tilt as R.O.B.'s fastest attack. Its first hit can be repeated by holding the attack button, and can also jab lock opponents, while the second hit is useful for spacing.
|ftiltname=S2
|ftiltdmg=7% (body), 8% (arm), 10% (arm's tip)
|ftiltdesc=A lunging hook. This attack can be angled; the tip of R.O.B.'s arm is decent for spacing, beginning at 50%.
|utiltname=Hi2
|utiltdmg=3% (hit 1), 5% (hit 2 tip), 6% (hit 2 middle)
|utiltdesc=Quickly thrusts his arms upward. It is good for starting combos into itself, up smash and up aerial from low to medium percentages, or functioning as an anti-air attack. However, it has very minimal horizontal range, which forces R.O.B. to practically stand next to a grounded opponent in order to land it.
|dtiltname=Lw2
|dtiltdmg=5%
|dtiltdesc=Quickly thrusts his arms diagonally downward. 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. Widely considered by many to be the best down tilt in the game and one of the best moves in the game overall due to its fast startup, low ending lag, good range, safety on shield, shield pressuring ability, and use as a combo starter and extender. 
|dashname=DashA
|dashdmg=7%
|dashdesc=A double [[Wikipedia:Professional wrestling attacks#Forearm club|forearm club]]. It can be followed up with forward aerial if the opponent's reaction is read properly.
|fsmashname=S3
|fsmashdmg={{ChargedSmashDmgSSBU|15}} (base), {{ChargedSmashDmgSSBU|11.5}} (middle), {{ChargedSmashDmgSSBU|6}} (tip)
|fsmashdesc=Fires a energy blast forwards, similar to the uncharged [[Robo Beam]]. Although this move has poor startup and is very punishable, the strongest hitbox closest to R.O.B.'s eyes deals extremely high knockback, KOing around 75% near the ledge. It can also be angled, allowing it to catch jumps and ledge options.
|usmashname=Hi3
|usmashdmg={{ChargedSmashDmgSSBU|3}} (hit 1), {{ChargedSmashDmgSSBU|14}} (hit 2)
|usmashdesc=Handstands 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 very powerful. It KOs middleweights at around 100%. Altogether, these traits make it a reliable KOing option, especially from [[out of shield]]. However, it has high ending lag and is very punishable.
|dsmashname=Lw3
|dsmashdmg={{ChargedSmashDmgSSBU|3.5}} (hits 1-2), {{ChargedSmashDmgSSBU|5}} (hit 3)
|dsmashdesc=Lowers his torso and spins many times doing a [[Wikipedia:Professional wrestling attacks#Clothesline|discus clothesline]], 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 offstage. Like forward and up smash, it also has high ending lag.
|nairname=AirN
|nairdmg={{ShortHopDmgSSBU|7.5}} (base), {{ShortHopDmgSSBU|9.5}} (tip)
|nairdesc=Activates his thrusters and somersaults and emit a fiery blast in a circular motion. Its large hitbox, very minimal landing lag, and ability to autocancel with a short hop collectively make it very useful for spacing, approaching and starting combos. If [[SHFF]]'d, it can reliably combo into forward air, Arm Rotor, or up air. It is also R.O.B.'s best landing option and is safe on shield. However, due to it hitting on frame 14, it is one of the slowest aerials of its type and can be stuffed out by faster aerials.
|fairname=AirF
|fairdmg={{ShortHopDmgSSBU|7}}
|fairdesc=Swings his arms forwards. 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=AirB
|bairdmg={{ShortHopDmgSSBU|15}} (base), {{ShortHopDmgSSBU|13}} (middle), {{ShortHopDmgSSBU|9}} (late base/middle)
|bairdesc=Leans forward and activates his thrusters to emit a fiery blast behind him. Very high power, but is very slow, coming out on frame 19, and has several sourspots. Back aerial can also be used for horizontal recovery, as it slightly propels him forward and does not consume [[Robo Burner]]'s fuel, and due to it briefly halting R.O.B's momentum, it can autocancel in a short hop, just like his other aerials. One of the strongest back airs in the game, KOing around 80% at the ledge.
|uairname=AirHi
|uairdmg={{ShortHopDmgSSBU|1.5}} (hits 1-4), {{ShortHopDmgSSBU|4}} (hit 5)
|uairdesc=Rapidly spins his arms upwards. It is R.O.B. second fastest aerial attack. 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.
|dairname=AirLw
|dairdmg={{ShortHopDmgSSBU|12}} (base), {{ShortHopDmgSSBU|11}} (middle), {{ShortHopDmgSSBU|6}} (tip)
|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. Auto-cancels in a short hop due to it stopping R.O.B's momentum for a while. 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 12 frames of landing lag, it is punishable if it is not spaced properly and auto-canceled, though not to the same extent as in ''SSB4''.
|grabname=Grab ({{ja|つかみ|Tsukami}})
|grabdesc=[[wikipedia:Clinch fighting|Clinches]] the opponent. All of R.O.B's grabs are extremely fast, but have terrible range.
|pummelname=CatchA
|pummeldmg=1.3%
|pummeldesc=A headbutt.
|fthrowname=ThrowF
|fthrowdmg=8%
|fthrowdesc=While holding the opponent in his hand, R.O.B. pulls his arm back and then flings it forward, throwing them away. Has minimal ending lag, giving it some combo potential at low percents.
|bthrowname=ThrowB
|bthrowdmg=10%
|bthrowdesc=Flings the opponent behind him with both of his arms. If fully charged beforehand, Gyro can follow up from a back throw from low to mid percentages.
|uthrowname=ThrowHi
|uthrowdmg=12%
|uthrowdesc=A [[Wikipedia:Piledriver (professional wrestling)#Reverse piledriver|jumping reverse piledriver]]. It can combo reliably into forward air, forward tilt, up tilt, or up air at a wide range of percents. It is also a useful KO throw, KOing around 160% from ground level and even earlier if R.O.B. has rage and/or lands on a platform.
|dthrowname=ThrowLw
|dthrowdmg=5%
|dthrowdesc=R.O.B. flips the opponent over and drills them into the ground headfirst, [[bury]]ing them. Depending on the opponent's mashing, R.O.B. can follow up with an up tilt, up air, or up smash.
|floorfname=&nbsp;
|floorfdmg=7%
|floorfdesc=Punches around himself while getting up.
|floorbname=&nbsp;
|floorbdmg=7%
|floorbdesc=Punches in front of himself and then behind himself while getting up.
|floortname=&nbsp;
|floortdmg=5%
|floortdesc=Spins his torso around to throw a low-angle hook around himself while getting up.
|edgename=&nbsp;
|edgedmg=9%
|edgedesc=Swings his base forward and activates his thrusters to emit a fiery blast forward while climbing up. Despite the appearance, it doesn't possess a flame hitbox.
|nsname=Robo Beam
|nsdmg=7% (Uncharged Robo Beam), 11.5% (point-blank Robo Beam), 4.5% (long range Robo Beam), 22% (point-blank Super Robo Beam), 15% (long range Super Robo Beam)
|nsdesc=An optical laser with 3 different levels: '''Uncharged Robo Beam''', '''Robo Beam''', and '''Super Robo Beam'''. Uncharged Robo Beam 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 allows 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.

The light on R.O.B.'s head indicates the level: a dim, slow-paced pulsating glow indicates an Uncharged Robo Beam; a brighter, moderate-paced pulsating glow indicates Robo Beam; and a bright, rapid-paced pulsating glow indicates Super Robo Beam.
|ssname=Arm Rotor
|ssdmg=1.5% (loop), 3% (last)<br/>1.5× (reflected projectiles)
|ssdesc=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. It can also [[reflect]] projectiles and move R.O.B. forward or backward while the [[control stick]] is tilted in the respective direction. An infamous combo finisher, possessing extremely high base knockback. It will KO most opponents offstage below 70% but struggles to KO onstage due to its poor knockback growth.
|usname=Robo Burner
|usdmg=—
|usdesc=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, indicated by the gauge in his chassis, to use in order to perform this move. Fuel is recovered over time as long as R.O.B. is grounded. This doesn't cause [[helpless]]ness, allowing R.O.B. to [[fast fall]], [[air dodge]], or attack with any aerials or any of his other specials either through its duration or after its conclusion. 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.
|dsname=Gyro
|dsdmg=6.1%-8.7% (uncharged), 7.2%-10.8% (fully charged), 5% (idle Gyro)
|dsdesc=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. Only one Gyro can be active at a time, and attempting another will result in R.O.B. flailing in confusion. If R.O.B. is holding his Gyro, he will be able to charge it again. Typically, an idle Gyro deals little knockback when touched, albeit enough to harass anyone trying to get past and even perform a [[lock]]. Its sheer versatility as a combo and stage control tool make it one of the best projectiles in the game. 
|fsname=Guided Robo Beam
|fsdmg=1.2% (homing lasers), 1% (laser loop), 3% (enlarged laser loop)
|fsdesc=Re-configures his body into a cannon-like form, and begins to charge energy. During the charge, he fires smaller red lasers that home on opponents in front of him. He then unleashes the built-up energy in the form of a green laser, which can be angled up or down. As the Final Smash begins to end, the laser briefly enlarges, becoming wider and more powerful.

After halting, he spins his arms in alternating directions and rotates his head 360° counterclockwise. Afterward, he adjusts his arms to face upward, continuously raising and lowering them in a flexing gesture. R.O.B.'s head also rotates 360° clockwise after every two times he pumps his arms.
*'''Up:''' Uses [[Robo Burner]], spins, and then lands. He then proceeds to continuously lower and raise his arms while rotating his head.
*'''Right:''' Turns his head and flashes the lights in his eyes while clapping, similar to his side taunt. He then proceeds to continuously clap, lowering his arms after each clap.

==In competitive play==
From the start of the game, R.O.B. has always been considered to have significantly improved from ''Smash 4''. With better approach options, more versatile projectiles with Gyro and Robo Beam, even more threatening KO options, and an improved edgeguarding game, he has always been seen as an excellent zoner with a wide array of utility options. R.O.B. also benefits from some of the universal changes in Ultimate with the 3 frame jumpsquat and reduced landing lag on aerials. Because of this, he was immediately seen as a competitively viable character. He has consistently seen strong results and representation from players, such as {{Sm|WaDi}}, {{Sm|Zackray}}, {{Sm|Raffi-X}}, and {{Sm|8BitMan}}. {{Sm|Armada}}, {{Sm|ZeRo}}, {{Sm|ESAM}}, and {{Sm|Dabuz}} view R.O.B. as an upper high tier or even a top tier, according to {{Sm|Mew2King}}. Additionally, R.O.B.'s match-up spread is strong as well, having even or positive match-ups against meta relevant characters such as {{SSBU|Joker}}, {{SSBU|Wolf}}, {{SSBU|Shulk}}, {{SSBU|Pokémon Trainer}}, {{SSBU|Olimar}}, {{SSBU|Pac-Man}}, and {{SSBU|Min Min}}, although he has disadvantageous match-ups against characters such as {{SSBU|Pikachu}}, {{SSBU|Mr. Game & Watch}}, {{SSBU|Mario}}, and {{SSBU|Young Link}}.

In online tournaments, which were the standard during the worldwide COVID-19 pandemic, causing almost all offline tournaments to switch to online, R.O.B. fares better, due to his already safe aerials and tilts being much more reliable due to lag. Many players, including {{Sm|Epic_Gabriel}}, Raffi-X, and {{Sm|Benny&TheJets}}, have performed fairly well in Wi-Fi tournaments, including various Ultimate Naifu Wars, The Quarantine Series, and {{Trn|The Box}}.

Even after offline returned, R.O.B. has continued to thrive, thanks largely to the aforementioned players, being by far the most common character at nearly every major tournament and gaining the overall best results of any character in the cast. Despite this, he notably is much less common in the later stages of bracket; while he is near-universally considered top tier due to his ubiquity, his true viability at the absolute top level of play remains questionable.

R.O.B.'s opponents all wear masks or lack expressive faces. His boss, [[Galleom]], fits in with the theme due to being a robot and lacking an expressive face.

==Role in [[World of Light]]==
[[File:WoL-42ROB.jpg|thumb|Finding R.O.B. in World of Light|left]]
Although R.O.B. was absent from the World of Light opening cutscene, he was vaporized and later imprisoned alongside the rest of the fighters (excluding {{SSBU|Kirby}}) when Galeem unleashed his beams of light.

R.O.B. was one of the many fighters that fell under [[Dharkon]]'s control upon Galeem's first defeat. He can be found in the [[Mysterious Dimension]] sub-area, as the fighter closest to the entrance, standing in a floating island with scattered mechanical junk. To reach him, the player must first defeat the spirit of [[List of spirits (Animal Crossing series)#Redd|Redd]] as the answer to a trivia question ("Which of these spirits sells furniture?"), allowing access to the island he's in.

==[[Spirit]]s==
R.O.B.'s fighter spirit can be obtained by completing {{SSBU|Classic Mode}}. It is also available periodically for purchase in the shop for 300 Gold, but only after R.O.B. has been unlocked. Unlocking R.O.B. in World of Light allows the player to preview the first spirit below in the Spirit List under the name "???". As a fighter spirit, it cannot be used in Spirit Battles and is purely aesthetic. His fighter spirit has an alternate version that replaces it with his artwork in ''Ultimate''.

Additionally, R.O.B. makes an appearance in a few support spirits.

==[[Alternate costume (SSBU)#R.O.B.|Alternate costumes]]==
As in ''SSB4'', R.O.B.'s default costume switches between the 1st and 2nd costumes listed here depending on the language the game is set to. The Famicom colors are the default if the language is set to Japanese, Korean, or Chinese, while the NES colors are the default color if the language is set to any other language. Newly scanned R.O.B amiibos default to the language's default color instead of the color of the R.O.B amiibo, unlike other amiibo variants.

==Trivia==
{{ImageCaption|File:Regigigas ROB Japan.jpg|File:Regigigas ROB USA.jpg|width1=160x160px|width2=160x160px|align  = right|caption=A comparison of {{h2|List of spirits (Pokémon series)|Regigigas}} Spirit Battle in the<br>Japanese, Chinese, and Korean versions (left) vs.<br>other languages (right), showing the difference<br> between language versions on R.O.B.'s default<br>costumes.}}
*R.O.B.'s stock icon is one of only five in ''Ultimate'' to show eyes, the others being {{SSBU|Kirby}}, {{SSBU|Meta Knight}}, {{SSBU|Sonic}}, and {{SSBU|Enderman}}.
*On the official site for ''Ultimate'', each character is accompanied by a background image of a stage from their universe. As R.O.B. is the only character to not have a stage from his home universe, his page is the only one with no stage for the background image.
*R.O.B. is one of four characters that has appeared in all games with Final Smashes to have a different Final Smash in each of them; the other three are [[Pit]], [[Zero Suit Samus]], and [[King Dedede]].
*The scripts for [[Super Diffusion Beam]] were never removed from the game's code in the transition from ''Smash 4'' to ''Ultimate''. However, like the glide attack scripts from ''Smash 4'', they lie dormant.
*In the Korean version, R.O.B. uses the "Robot" [[announcer]] voice clip from the Japanese version, despite R.O.B.'s name being written the same way as in the English version. This is unlike {{SSBU|King Dedede}}, {{SSBU|Simon}}, and {{SSBU|Richter}}, all of whom use the English announcer voice clip due to the pronunciation. This was not the case in ''Brawl''.
*R.O.B. and the {{SSBU|Ice Climbers}} are the only fighters that cannot receive a series bonus, since they don't have any primary spirits from their own series.
**Previously prior to the 10.1.0 update patch, {{SSBU|Cloud}} also shared this distinction.
*{{SSBU|Bowser Jr.}}, {{SSBU|Yoshi}}, {{SSBU|Mr. Game & Watch}}, and R.O.B. are the only fighters who used their default costumes in spirit battles through one of the 1297 spirits available when the game first launched. In R.O.B.'s case, it is due to the [[Ancient Minister]] spirit.
**Due to certain spirit battles (such as Ancient Minister, Villager & Iron Golem, Diminutive Guardian, and E.M.M.I), R.O.B. is the only character whose color scheme used for a spirit battle changes based on the language version used.
*R.O.B.'s NES color scheme is the only one which bears the NES' base sticker which reads "Robotic Operating Buddy"; all other palettes bear the Famicom base sticker, which reads "Family Computer Robot". Famicom is short for "Family Computer."
*Although R.O.B. is "voiced", in [[Stamina Mode]], he stays silent when he gets KO'd by reaching 0 HP with no stocks remaining. {{SSBU|Mr. Game & Watch}} and the {{SSBU|Mii Fighter}}s also share this oddity.
*Many of R.O.B.'s move names are based on the raw file names for moves in the game.
