Pikachu is a lightweight with a small hurtbox, tied with Kirby, Olimar, Sephiroth, and Mewtwo for the seventh lightest fighter. It has overall good mobility, possessing fast walking and dashing speeds, high jumps, is tied for the ninth-highest air acceleration, and has the fourth-highest traction, but slightly above average falling speed and gravity and below-average air speed. Due to its fast mobility, a strong projectile in Thunder Jolt, exceptional frame data, and among the fastest defensive options, Pikachu has an exceptional neutral game and rarely struggles to approach.
Pikachu's main strengths are its fast frame data and dominant edgeguarding game, with each being considered among the best of the cast. This is mainly due to Pikachu's aerials, each of which can autocancel in a short hop. Its neutral, forward, back, and up aerials are fast, all of them except for up aerial being multihit attacks that can combo into each other and most of Pikachu's other moves, with their extremely low ending lag making them excellent for combos, edgeguarding, and potential zero-to-deaths. Forward and back aerials in particular are notoriously effective as neutral options due to their animations low-profiling Pikachu's already small hurtbox, which makes them notably hard for most characters to punish out of shield. Up aerial is a fantastic juggling option to boot, while neutral aerial notably converts into both up smash and down smash if used while landing, making it Pikachu's most reliable method of confirming KOs at high percentages. Down aerial can meteor smash in its first two active frames and is fast for a move of its category, with its long-lasting hitbox making it an extremely potent edgeguarding option as well. Down aerial also is its only aerial with over 20 frames of ending lag, though it still has relatively low lag compared to other meteor smashes of its kind.
Another notable strength Pikachu has is its ability to escape pressure. It boasts a frame 2 air dodge and incredibly small hurtbox, which combined with its light weight and fantastic frame data make it among the most difficult characters to combo. The speed and versatility of its up special Quick Attack makes it trivial to land and escape disadvantage compared to the majority of the cast, while its aforementioned frame data gives it one of the strongest out of shield games through its neutral aerial, back aerial, and up smash. It additionally boasts a phenomenal recovery, with Quick Attack's long distance and multiple angles (there must be a difference of 30 degrees between each jolt's arc, or the second jolt will not come out) making it exceptionally difficult to edgeguard, and its side special Skull Bash providing additional horizontal distance if necessary despite being risky to use. All in all, Pikachu boasts an incredible disadvantage state that allows him to rapidly and effectively reverse the situation on the opponent if they make a single mistake.
Pikachu has a potent grab and throw game despite its poor grab range. It has a fast pummel and its forward and back throws are good for setting up edgeguards, with back throw also being able to KO near the ledge at high percents. Its up throw can combo into down special Thunder and reliably KOs middleweights around 170%. Down throw is a fantastic combo starter, being able to combo into Thunder and all of Pikachu's aerials setting up "nair loops" which involves using dragdown nair and up tilt to rack up damage while reacting to the DI of the opponent to continue the combo. It can also lead into various combos and kill confirms depending on the opponent's DI, including up air bridges which can take the opponent all the way offstage before Pikachu KOs them with a forward air. Extending Pikachu's notorious combo game revolves around using its aerial attacks to drag the opponent down, thereby extending the combo further. Thunder Jolt also complements its advantage state nicely as it can combo into any of Pikachu's moveset or be used to pressure the opponent and make them hesitatingly pick options while under pressure.
Pikachu is not without weaknesses, however. All of its normal attacks excluding forward smash have poor range, with most of said attacks being barely disjointed or not at all. Because of its lack of range, Pikachu tends to rely on using Thunder Jolt to help it approach the opponent. It gets KO'd relatively early due to its diminutive weight, and it also bears inconsistent raw KO power itself. Dash attack is powerful but extremely unsafe if whiffed, up throw doesn't KO under 170% without rage, and its forward and up smashes are burdened by several sourspots that make them unwieldly to use. Beyond this, none of its aerials are strong enough to KO reliably while onstage, and its other KO moves (down smash, forward tilt, and back throw) are unfit for KOing until around 150% by the ledge. While Thunder is powerful, it has slow start-up and high ending lag that limits its usage to being a situational combo finisher and edgeguarding option. A notable weakness in Pikachu's otherwise potent neutral is its inability to trade due to many of its aerials being multihits, meaning that if a trade occurs Pikachu will deal about 1% while taking the full damage of the move it trades with, a substantial weakness considering how light the character is.
Overall, Pikachu's strengths outweigh its weaknesses and it is universally considered to be a top-tier character, with many proclaiming it as the single best character in the game.
Changes from Super Smash Bros. 4
At the end of SSB4's metagame, Pikachu was considered a high tier character (ranked 15th out of 55 characters). In its transition to Ultimate, Pikachu has been heavily buffed. All of its moveset's aspects were greatly improved during its transition, in addition to its moveset benefiting noticeably from the changes to gameplay mechanics.
Pikachu's largest buffs arguably come from its improved speed: its already above-average mobility has been increased, many of its moves have less ending lag, and its aerials have drastically reduced landing lag; while the former and latter buffs are shared with the rest of the cast, they especially benefit Pikachu, the former due to its small size and the latter since its aerials had among the highest landing lag in SSB4. These buffs improve Pikachu's neutral game and overall comboing capabilities plus, due to its "pancaking" during many of their landing animations, allow it to avoid mistimed attacks with more ease and retaliate. To further complement this, its already great air game was enhanced as well: Pikachu has a new neutral aerial that acts similarly to Mewtwo's own and has much more combo potential; both forward and up aerials have increased KO power, alleviating one of Pikachu's biggest weaknesses in SSB4; back aerial auto-cancels from a short hop, now consistently launches opponents behind Pikachu, and has a faster animation, which gives it combo potential into itself several times at low percentages, to the point it's able to perform a pseudo-Wall of Pain with the move; and down aerial now has a clean hitbox that meteor smashes opponents, further improving Pikachu's aerial KOing ability.
Although not as buffed as its aerial game, Pikachu's other moves have also seen noteworthy improvements. In particular, dash attack has increased KO power and significantly increased shieldstun, to the point it is now unpunishable on shield. Forward smash has increased range, making it a more dangerous tool for trapping opponents on the edge; up smash's strong hit lasts longer, making it more reliable for KOing; and down smash will always send opponents in the direction Pikachu faces and at a lower angle, making it more useful, as well as gaining a KO confirm into it from Pikachu's new neutral aerial. Pikachu's standing grab extends farther; down throw now inflicts additional hit lag on the opponent on release, improving its combo ability; and up throw has increased knockback, allowing it to KO at high percentages. On top of this, some of its special moves were significantly buffed, as Thunder Jolt has less ending lag, which improves Pikachu's neutral game and grants it a trapping option if opponents shield it from far away; Skull Bash has drastically reduced ending lag on hit, making it much safer unless it is perfect shielded; and Thunder's cloud hitbox deals set knockback, allowing it to connect consistently into the discharge, which also inflicts much more knockback.
Finally, Pikachu notably benefits from the changes to game mechanics. The new limits to air dodges and smaller edge sweetspot sizes make Pikachu's already great edgeguarding prowess more dangerous, especially with down aerial's new meteor smash hitbox, its stronger aerial attacks all-around, and improved primary projectile in Thunder Jolt; they also don't impair its disadvantage state much thanks to its long-distanced and unpredictable recovery. The changes to air dodging also make its on-stage offense even more effective, which combined with its improved mobility, streamlined jumpsquat, and reintroduction of dash-dancing allow it to chase opponents, giving it an excellent combo game that has the potential of causing zero-to-death combos. The nerfs to rage also notably improves its poor endurance, while not nerfing its KOing ability due to its stronger moveset.
In spite of mostly receiving drastic buffs, Pikachu is not without a few nerfs. The most significant nerf Pikachu has received is the removal of Quick Attack canceling, which noticeably reduces its mobility and approach options, making it more predictable. The changes to neutral aerial, in lieu of an improved combo game, also remove its KO potential. The increased startup and ending lag on its grabs, and dash grab and pivot grab not reaching as far, limit the benefits its grab game has received. Lastly, up throw's altered knockback, while giving it KO potential, makes it more difficult for Pikachu to combo into Thunder. Outside of these nerfs, however, other nerfs Pikachu received have generally been minor, while a good amount of the buffs it received make up for said shortcomings, most notably its improved neutral game.
In the end, Pikachu's entire moveset has seen drastic improvements all-around, it benefits significantly from the new engine, and its limited KOing ability was mostly alleviated, causing its buffs to severely outweigh the nerfs it received. Although Pikachu still suffers from the same weaknesses that plagued it in SSB4, such as short-range, poor endurance, and still limited KOing ability, its improved strengths now more than compensate for its shortcomings, arguably cementing it as the most viable threat between its fellow "fragile speedster" brethren, alongside its clone Pichu. While Pikachu is not as common as some other top- or high-tier characters, it has still received strong results in competitive play, courtesy of players like ESAM and Captain L. This has led to a very strikingly positive reception of Pikachu, with many top players describing it as a top 5 character in the game, with some going as far as considering it the single best character, although this is debatable as its results are not as strong as other top-tier contenders. Regardless, Pikachu is considered much better than in SSB4, and has fared significantly better overall than in previous games (bar its appearance in SSB).
Throws and other attacks
Pikachu was slightly buffed via game updates. Its grab game was slightly improved, thanks to a faster pummel and larger grabboxes. The only nerf it has received is Thunder Jolt's shield damage being slightly decreased as part of a near-universal nerf to projectiles. His shield size was also increased as a part of a near-universal buffs to shields.
While Pikachu does fare slightly better since the launch of Ultimate, the changes it received were very minor overall, and as a result the general opinion of Pikachu being a very powerful and top tier character in the competitive scene has remained the same since day one.

In competitive play
Opinions of Pikachu have been very strong since before the game's release. Its overall favorable adjustments, especially its new and potent neutral aerial, influenced many players to rank it as a top-tier character, with some (notably ESAM) claiming Pikachu was overpowered during the demo. Pikachu's strong matchups across the vast majority of the cast enabled it to have a robust metagame, and it could still do quite well against potentially troubling matchups such as Mr. Game & Watch, Ness, and Mario. This perception became more evident with nerfs given in the game's early stages to other strong characters such as Pichu, Wolf, Olimar, and Peach. Many top players such as MKLeo and ESAM notably consider Pikachu to be either the best in the game or among one of the best characters overall.
Despite these claims and high reception by top players, Pikachu's playerbase is noticeably smaller compared to other top-tier contenders. Furthermore, its results in major tournaments are rather weak in comparison with ESAM being the only Pikachu player to have consistently high placements in national-level tournaments. As such Pikachu's viability remains up for debate, with some top players such as Dabuz questioning if the claims made by players reflect its actual viability. Regardless, it is widely considered to be a top-tier character.

Classic Mode: I Choose You!
Pikachu fights against other Pokémon on various Pokémon stages, with Poké Balls as the only available item. Excluding Mewtwo, the opponents are ordered by their National Pokédex number. The title is a reference to Ash Ketchum's signature catchphrase in the Pokémon anime, which doubles as the title of the first episode and the 20th movie.
Credits roll after completing Classic Mode. Completing it as Pikachu has Road to Viridian City - Pokémon Red / Pokémon Blue accompany the credits.
Character unlock tree
Pikachu's Classic Mode character unlock tree includes the following characters in order:
Each character can be unlocked by clearing Pikachu's Classic Mode, or the Classic Mode of any preceding character, if all preceding characters have been unlocked. Once all the above characters are unlocked, clearing Classic Mode with any of them will default to Mario's character unlock tree, starting with Sonic.
Role in World of Light
Pikachu was among the fighters summoned to the cliffside to fight an army of Master Hands.
During the opening cutscene, Pikachu was present on the cliffside when Galeem unleashed his beams of light. While attempting to run away, Pikachu was noticed by Sonic, who slowed down for Pikachu in an attempt to save it. However, both of them were vaporized and placed under Galeem's imprisonment along with the rest of the fighters, except for Kirby.
Pikachu can later be found stuck on an island that can only be accessed by falling into the current of a waterfall, then the player must confront the spirit of Esna before they can battle to awaken it.
Pikachu's default fighter spirit can be obtained by completing Classic Mode. It is also available periodically for purchase in the shop for 300 Gold. Unlocking Pikachu 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. Its Pikachu Libre outfit has a fighter spirit of its own, available through the shop. Each fighter spirit has an alternate version that replaces them with their artwork in Ultimate.
Additionally, Pikachu makes an appearance in a few support spirits.
