Editing Robin (SSBU)

Robin's special moves have been heavily revamped. With the exception of the uncharged version, all versions of {{b|Thunder|Robin}} hit much harder and now function as effective KO moves, especially Thoron; the move can now also be [[charge-cancel]]ed by jumping. [[Arcfire]] is much harder to escape from and travels much farther, making it even more effective for combo initiating. [[Elwind]] can have its trajectory significantly altered and grants more distance, recharges faster, and pushes opponents if the wind blades hit the ground. Finally, [[Nosferatu]] has slightly more range, heals and deals damage at a faster rate; while it has fewer uses, this also allows it to generate a used tome much faster.

However, Robin's nerfs are also notable. The biggest change is to the Levin Sword, which Robin no longer starts with at the start of the match, forcing several seconds of downtime before the Levin Sword is usable. Robin's most effective tools have also been nerfed: Arcthunder's significantly lower looping duration now prevents followups unless initiated at a distance, Elwind has fewer uses, and down throw has increased knockback, reducing the percent range in which combos (such as the "Checkmate", a down throw to up aerial) can be performed. Arcfire's fire pillar now possesses a hitbox that can cancel other moves; while this allows it to cancel other projectiles and gives it use at counterzoning, the fact it can be canceled by any other hitbox makes it less reliable for ledge-trapping under some circumstances.

Universal changes to gameplay mechanics are a mixed bag for Robin, but have hurt him overall. The universal reduction to [[landing lag]] now creates safer landing options (especially with the Levin Sword's high shieldstun), and the streamlined jumpsquats allows Robin to take advantage of his extremely powerful aerials faster. The changes to [[air dodge]]s now makes it easier for Robin to pressure the opponent through his powerful projectiles and sword attacks, and the introduction of directional air dodges gives Robin an emergency recovery option if he lacks Elwind. However, Robin is significantly harmed by the universal increases to mobility; despite sporting faster mobility like the rest of the cast, Robin's own mobility hasn't seen an improvement notable enough to allow him to catch up to other characters, still being one of the slowest characters in terms of grounded mobility unless he resorts to fox-trotting. As a result of this, and other veterans' faster movement, it is now easier to overwhelm Robin, while his tools don't allow him with some form of dealing with pressure.

Overall, Robin's playstyle, while essentially left unchanged from ''SSB4'', has nonetheless been improved, allowing him to play to his strengths with more ease, and many of his worst issues have been patched up. However, his worsened down throw combos have removed his previously guaranteed KO setup, forcing Robin to find other setup methods to KO the opponent, though thanks to Arcfire's utility, this isn't as big of an issue. That being said, Robin still possesses some of his former flaws, such as problems with escaping pressure, a few awkward hitboxes, and mediocre grounded mobility. The latter issue is especially prevalent due to the faster pace of ''Ultimate'', which brings the extent of many of Robin's buffs into question; the game's engine now prioritizes faster, more aggressive playstyles, and the prevalence of fast characters has caused Robin's powerful neutral game and disadvantage state to be worse than before. In bulk, Robin's changes have not significantly improved his standing, instead performing worse relative to the cast in ''Ultimate'' than in ''SSB4''.
