Classic Mode (SSBU)

Classic Mode loading screen in Super Smash Bros. Ultimate.

Classic Mode (勝ちあがり乱闘, Survival Smash) is a single-player (optionally 2 players) mode in Super Smash Bros. Ultimate. Each character now has their own predetermined set of opponents and stages to face in this mode. A unique name is given to each character's path, and there may be special rules or conditions: for example, Ryu's path references Street Fighter II by using only Ω forms and Stamina mode alongside the fighters most closely representing the characters of Street Fighter II. It is different from the Classic Mode versions found in the two versions of SSB4, shown by the return to the style of Classic Mode that was in Melee and Brawl. Just like in Super Smash Bros. for Wii U, Classic Mode can also be challenged by two players. When playing with two players, the route will always be based on Player 1's character. 1v1 battles become 2v2 battles with two of the same opponent, one in an alternate costume. If P2 chooses the same costume as an opponent, the opponent will not switch to another costume.

Similar to the Classic Modes for the previous entries, players can select an intensity level, indicated by the position of the lengthy mural. The highest allowed starting intensity is 5.0, and it will increase slightly, depending on how well the player does, after each victory, to a maximum of 9.9. Winning in fast times or with great dominance awards a "Nice Play!" label for the stage, and an intensity boost ranging from 0.6 to 1.3, depending also on how far along the player is in the game. Otherwise, the game's default intensity boost goes between 0.2 and 0.6, lower scores being awarded to long battles with more damage taken. The layout consists of seven stages plus a bonus stage. Unlike previous entries, the opponent in the last stage is not always Master Hand or Crazy Hand; each fighter has a different encounter at the end. Scores are also present in Classic Mode, which is displayed alongside the player's Global Smash Power.

Players only have one stock, unlike previous installments. To continue, the player can either spend Gold, which lowers the intensity by 0.7 points or use a Classic Mode ticket to keep the current intensity. Upon continuing, the match will start from where the player left off. Using a Classic Mode ticket at any point during the run will stop the intensity from rising to 9.9, making the maximum possible intensity 9.8 for the rest of the run. However, it will not degrade a run already at intensity 9.9 if the ticket is used then. When playing with two players, the round does not fail until both players' stocks are lost.

Clearing Classic Mode with a character grants their fighter spirit, much like trophies from previous games.

Types of battles

Regular stage

Regular stages include Smash 1v1, 2v2, and Free-For-All battles where all enemy fighters must be defeated to proceed. Some variations include Giant Battles, where at least one opponent is giant, Metal Battles, where at least one opponent is metal, and Multi-Man Battles, where eight or less enemies are fought three at a time. When playing with two players, the 1v1 battles are replaced with 2v1v1 battles against two copies of the same opponent, and any allies granted by the match are overwritten by the co-op player.

Bonus Game

This is a challenge in the style of Race to the Finish, but rather than having a time limit, the player must run from a black hole that consumes the stage behind them. Glowing orbs are scattered throughout the side-scrolling area which increases the player's score, some behind breakable blocks and bomb blocks that encourage the player to go out of their way as the void closes in. Some scattered physics objects impede progress in a similar manner to Trophy Rush. At the end of the stage, a cannon blasts the player into a portal that ends the Bonus Game.

Boss

Most fighters face a predetermined boss fight at the end of their route. The player must deplete the boss's HP in order to defeat them. The most common boss is Master Hand on Final Destination, with Crazy Hand joining in higher difficulties, similarly to previous games. A select few characters replace Master Hand and Crazy Hand with either Rathalos, Dracula, Giga Bowser, Marx, Galleom or Ganon, and certain others may feature Crazy Hand with Master Hand regardless of difficulty, reverse Crazy Hand and Master Hand's roles, or be on an Ω form of another stage. Additionally, there are a few instances where another fighter is part of the final round:

• Both Mario and Captain Falcon fight Bowser in their final round before fighting Giga Bowser.
• Both Pikachu and Pokémon Trainer fight Mewtwo in their final rounds before fighting Master Hand.
• Jigglypuff fights a giant Donkey Kong, and does not fight a boss at all in its route.
• Bowser fights Rathalos in his penultimate round, but his final round is against Mario, then Metal Mario.
• Zelda fights Ganondorf in her final round before fighting Ganon.
• Mega Man fights Galleom in his penultimate round, but his final round is against Dr. Mario, then Mewtwo.
• Bayonetta fights a giant Palutena, and does not fight a boss at all in her route.
• Hero fights Rathalos in his fourth round, but fights Robin in his blue costume and then a Giant Charizard in its purple costume for his final round.
• Terry simultaneously fights Ryu, Ken, and another Terry in his final round, and does not fight a boss at all in his route.

After defeating Bowser, Ganondorf or Mewtwo in the boss round, the player is given a Maxim Tomato.

The boss of this route is Dracula.
Richter	Smash Echoes (ダッシュファイターズ, Dash Fighters)	Both the English and Japanese names refer to Echo Fighters, which make up all of Richter's opponents on this route. The boss of this route is Dracula.
King K. Rool	Super Heavyweight Class (ヘビー級のキケンなヤツら, Dangerous Heavyweight Guys)	The title uses boxing terminology, referencing the final boss battle of Donkey Kong 64. King K. Rool's opponents are the heaviest characters in the game, with most of them being antagonists. His penultimate battle is with his nemesis, Donkey Kong. The boss of this route is Galleom, who is a heavyweight among bosses, being one of the largest.
Isabelle	Best in Show (紅23点, 23 Red Flowers)	The English name refers to conformation shows. The Japanese name is a pun on the phrase 紅一点, which translates to "one red flower (in a field of green)" but figuratively means "the only woman in a group of men". All of Isabelle's allies and opponents are female save for Popo of the Ice Climbers in Round 4, for a total of 23 female participants. The boss of this route is Master Hand.
Incineroar	Burning Pro Wrestling Spirit! (こわもてヒールのプロレスリング, The Pro Wrestling of a Hard-faced Heel)	All battles take place on Boxing Ring in three different forms and feature opponents who use wrestling moves, such as Bowser, Donkey Kong, and King K. Rool. The penultimate battle is a mirror match against another Incineroar, and the bosses of this route are Master Hand and Crazy Hand, with Greninja as the player's partner.
Piranha Plant	New Bloom (花の新人王, Floral Rookie of the Year)	All of the opponents are the newcomers for the base game. It also references Piranha Plant being the last newcomer revealed prior to the games launch. Each stage is based on the reveal trailer for one particular newcomer, in the order in which they were released. The boss of this route is Rathalos, likely because it is a boss from a newly represented universe.
Joker	Shadows (シャドウを追え, Follow the Shadow)	The title refers to a reoccurring element in the Persona series, Shadows. All of the opponents use dark alternate costumes. With the exception of the first and final round, Joker is joined by a character from the previous round using a light alternate costume. All rounds (except Round 2) take place on Mementos in three different forms. The boss of this route is Master Hand (who, coincidentally, shares the same English voice actor as Joker) on Ω form Mementos rather than Final Destination, referencing the god Yaldabaoth.
Hero	A History of Heroism (勇者たちの記憶, Memory of the Heroes)	All battles against tiny opponents (except for the last one) are stamina battles. The first, fourth, and seventh battles represent the progression of a typical Dragon Quest game. The first battle is against a Tiny Kirby team who represent weak enemies like Slimes. The fourth battle is against Rathalos, representing a mid-boss. The final battle is against Robin, who is replaced by a Giant Charizard upon defeat, representing Dragonlord: a two-phase final boss and the main antagonist of the original Dragon Quest game. The other four battles are against each of the playable Dragon Quest protagonists, with stage choices and companions appropriate to the specific entries in the series they originally come from.
Banjo & Kazooie	Perfect Partners (ぼくらでこぼこパートナー, Our Bumpy Partnership)	All battles consist of duos of each series either as a two-in-one character, or two characters from a particular series. The penultimate battle is against Diddy Kong and Donkey Kong as a reference to both the Banjo-Kazooie and Donkey Kong series being developed by Rare Ltd.. Additionally, Duck Hunt references the similarities between the characters with Duck Hunt using the palette swap most similar to Banjo & Kazooie. The music and stage combinations reference the various worlds from Banjo-Kazooie. The bosses of this route are Master Hand and Crazy Hand, referencing Motzand (the piano-playing ghost hand that appeared in Mad Monster Mansion), as well as the hands being a duo themselves.
Terry	The King of Smash (ザ・キング・オブ・大乱闘, The King of the Great Fray)	The title is a portmanteau of Super Smash Bros. and The King of Fighters. The Japanese title uses the Japanese name of the Smash series, 大乱闘スマッシュブラザーズ (Great Fray Smash Brothers). All battles are stamina battles against a team of three opponents, who each appear when one of their teammates has been defeated, similar to the 3-on-3 battles in The King of Fighters games. The enemy teams are made up of fighters who hail from the same series, or share a similar theme. Additionally, Ryu and Ken's appearances in the final battle references how they had previously crossed over in the SNK vs. Capcom games.
Byleth	A Heroic Legacy (紋章の系譜, Geneaology of the Emblem)	This route is themed around the different Fire Emblem games, fought in chronological order. The Japanese title of the route is a combination of two Fire Emblem games from the Super Famicom era: Monshou no Nazo (Mystery of the Emblem) and Seisen no Keifu (Geneaology of the Holy War). All battles are stamina battles. The player always starts with 100 HP, solo opponents have 100 HP, opponents in team battles have 50 HP, and CPU allies in last round start with 30 HP each. The penultimate battle is against three Byleths that represent the house leaders in Fire Emblem: Three Houses. The bosses of this route are Master Hand and Crazy Hand, and Marth, Roy, Ike, Robin and Corrin appear as partners.
Min Min	ARMS at the Ready (ウデ自慢たち 全員集合!, All of ARMS' pride!)	All opponents specialise in punching attacks or use arm mounted weapons. They also represent several ARMS characters. Notably, Round 1 is against a pair of Mii Brawlers dressed as ARMS characters Spring Man and Ribbon Girl, Round 2 is against Little Mac, referencing the similarities between ARMS and Punch-Out!!, and Round 5 is a Horde Battle against a team of R.O.B.s, referencing the 1 vs. 100 mode in ARMS. The boss of this route is Galleom who represents Hedlock after fusing with Max Brass or Dr. Coyle.
Steve	TBA

Unlocking criteria

All eight of the starter characters from the original Smash Bros. and Ultimate have their own character unlock paths, each with eight characters to unlock, except for Pikachu, who has seven. Completing Classic Mode with any character in a given path will challenge the player to a Challenger Approaching duel for the next available character from the start of their path down, as indicated in the table below. For example, beating Classic Mode with Donkey Kong will then trigger the fight to unlock Bowser. If Bowser is already unlocked (or his Challenger Approaching duel has already been issued), Pokémon Trainer will be unlocked next. When playing with two players, Player 1's fighter will be used to determine the next challenger.

When all the characters in a path are unlocked, completing Classic Mode with those characters will unlock the next available character in Mario's path, then Donkey Kong's, and so on. Completing Classic Mode with downloadable fighters will also unlock fighters in this order, as these characters are not assigned an unlock path.

Unlock stages and music are the same as in Vs. Mode. Notably, all clones, semi-clones, and pseudo-clones except for Ganondorf, Roy, and Chrom are in the same path as the character they are based on.
