Editing R.O.B. (SSBU)

Like in ''Brawl'' and ''Smash 4'', R.O.B. is a zoning-oriented character with versatile 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 possessing greater KO power. Thanks to R.O.B.'s [[item throw]]s being among the strongest in the game, Gyro is also especially useful when [[Item throw#Directions and strength|smash thrown]] as an item.

Aside from his projectiles, R.O.B.'s grounded game is also excellent. His [[neutral attack]] comes out on frame 3 and acts as a quick move at low percentages to escape pressuring situations, and it can also [[jab lock]] and combo. [[Forward tilt]] is useful for spacing since it comes out on frame 7, can kill at high percents, and can hit many characters' ledge hangs. [[Up tilt]] comes out on frame 4, and is great for acting as an anti-air and combos into his up aerial. [[Down tilt]] is R.O.B.'s single-best move in his entire kit, as it lowers his hurtbox, has great range, is tied with his jab as his fastest move at frame 3, pressures [[shield]]s, beats [[shield grab]]s, 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-based scenario for a KO at relatively low percentages. Lastly, [[dash attack]] is useful for punishing landings and whiffs, is extremely fast at frame 7, has relatively long range, and can combo into his forward air at low to medium percentages.

R.O.B.'s air game is also great, thanks to the excellent and disjointed ranges of all excluding [[forward aerial|one]] of his aerials. [[Neutral aerial]] has large, disjointed hitboxes that make it great for covering the opponents' options if lacking the range to deal with it. It is 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 KOing tool. [[Up aerial]] is a great vertical KO move due to its large and long-lasting hitboxes, fast startup, and the last hit’s high knockback. [[Back aerial|Back]] and [[down aerial]]s are R.O.B.'s most damaging aerials when [[sweetspot]]ted, and they too have large and disjointed hitboxes, much like neutral aerial. However, they also boast their own specific strengths: back aerial has recovery potential thanks to it propelling R.O.B. forward, and it is his only aerial that can KO in neutral due to its incredible knockback and huge hitbox. Meanwhile, his down aerial is a powerful [[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 is not disjointed.

R.O.B.'s [[grab]] game is also good. His [[Forward throw|forward]] and [[back throw]] are decent for setting up edgeguards, combos, and [[50-50]]s. The latter can also KO at the ledge at very high percents. R.O.B.'s [[up throw]] is his most useful: it is his most damaging throw, a passable KO move (especially 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 one of his best tools for sealing a stock. While it deals poor damage, it [[bury|buries]] opponents, allowing for follow-ups into an up tilt, up air, or even up smash. However, with excessive [[button mashing]], the opponent can typically get out before R.O.B. has any chance for a particularly strong followup. As such, it is more of a 50-50 rather than a reliable method for taking a stock.

Although R.O.B. possesses a large number of strengths, he does also have a few noteworthy shortcomings. Despite possessing a good chunk of respectable KOing options, landing a KO can often be problematic because of his finishers being burdened with either considerable lag and/or unimpressive range. The latter trait is especially noticeable in regard to R.O.B.'s arm-based attacks, most of which have short ranges, which further extends to R.O.B.'s [[grab]], which is among the shortest-ranged in ''Ultimate'' in comparison to his own size.

In addition to R.O.B.'s issues with his hitboxes, his hurtbox also hinders him, as it is both large and wide, meaning he can get hit by a lot of combos that other characters would have an easier time evading. This also means that he has difficulty dealing with combo-oriented characters. 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 sluggish in terms of startup, forward and up aerials only hit in front of and above R.O.B., respectively, and back aerial is a mixture of both: it has slow startup and only hits behind him.

Overall, R.O.B. is a non-traditional heavyweight zoner. His relatively quick mobility and overall above-average frame data allow him to easily pressure unwary opponents, and he lacks much trouble killing if he can gain the advantage. However, R.O.B. players must take high caution, as a single combo can be all it requires to get R.O.B. in an uncomfortable position or potentially even end a stock, thanks to his large size, moderately high weight, above-average falling speed, and lack of options to break free from combos.
