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 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 2v1v1 battles with two copies of the same opponent, usually in the second costume. In the case of Bowser in Peach's route, his 8th costume is used.

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 1.2, 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 longer 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, but intensity will only rise to a maximum of 0.3 regardless of how quickly the CPU opponent is defeated afterwards. 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.

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 outrun a void of darkness that consumes the stage behind them. Glowing orbs are scattered throughout the side-scrolling area which increase 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. In some cases, the boss is not the only challenge in the final stage; for example, Mario's and Captain Falcon's final stages features a regular battle on Final Destination against Bowser, who transforms into Giga Bowser and begins the boss fight upon his defeat. For Bowser and Mega Man, the boss is fought before the final stage. For the Hero, the boss is fought on Round 4. For Jigglypuff and Bayonetta, there is no true boss battle and the final stage instead consists of standard fights against a giant Donkey Kong for the former and a giant Palutena for the latter, respectively. Presently, the Classic Mode bosses include Giga Bowser, Ganon, Master Hand, Crazy Hand, Dracula, Galleom, Marx, and Rathalos. Characters that are assigned either Master Hand or Crazy Hand for their boss battles will fight both bosses simultaneously at intensity levels of 7.0 or higher, while certain characters (typically those accompanied by CPU allies in their final stage) will be assigned both Hands outright regardless of intensity. The exceptions to these rules are Pikachu and Pokémon Trainer, who will always fight a lone Master Hand immediately following a duel with Mewtwo. After defeating Bowser, Ganondorf or Mewtwo in the boss round, the character is given a Maxim Tomato.

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. 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 (except the last for unknown reasons) are stamina battles. The first, fourth, and seventh battles represent the progression of a typical Dragon Quest game. The first battle is against a 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.

Unlocking criteria

All eight of the starter characters from the original Smash Bros. and Ultimate have their own character unlock trees, each with eight characters to unlock, except for Pikachu, who has seven. Completing Classic Mode with any character in a given tree will challenge the player to a Challenger Approaching duel for the next available character from the top of their tree down, as indicated on the table below. For example, beating Classic Mode with either Link or Young Link will then trigger the fight to unlock King K. Rool. If K. Rool is already unlocked (or his Challenger Approaching duel has already been issued), Ice Climbers 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 tree are unlocked, completing Classic Mode with those characters will unlock the next available character in Mario's tree, 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 tree.

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 tree as the character they are based on.

Trivia

This trivia section is excessively long. Relevant facts should be integrated into the body of the article and unnecessary ones should be removed. You can discuss this issue on the talk page or edit this page to improve it.

• Super Smash Bros. Ultimate's Classic Mode is the only Classic Mode in which:
  • Each character has a predetermined route.
  • The final round features bosses other than Master Hand and Crazy Hand.
  • The player can have CPU allies in the final round.
  • Master Hand's solo fight, Crazy Hand's solo fight, and their tag-team battle have different themes.
  • Boss fights show a health bar for the bosses (like in World of Light) instead of percentages.
  • Not every playable character can play (due to Mii Fighters are absent from this mode).
  • The highest difficulty cannot be selected from the start.
  • Continues do not restart the current battle.
  • Every stage has used has predefined music, instead of picking one at random from that stage's music pool.
  • Not to have the announcer speaking between fights during the pre-match loading screens.
  • Not to have short movies for every fighter since it switched back to the congratulations screen image for every fighter.
• The banner represents every playable fighter in the base game in their default color scheme and costume, with the exception of Corrin, who is represented by the default female variant instead.
  • Despite appearing in the banner, the Mii Fighters themselves are not playable in Classic Mode. However, they are still fought in some of the routes.
• Ryu and Hero are the only characters who have stamina battles for each of their Classic Mode routes.
  • The only difference is that unlike Ryu, Hero has a normal stock battle rather than a stamina battle in the final level.
• Hero is the only character who can use the same costume as the CPU fighter. For other characters, when using the same costume as the enemy, the opponent will change the costume.
• While Norfair appears in more Classic Mode routes than any other stage (appearing in 13 different routes), Boxing Ring is the most common stage to fight opponents on (for 18 rounds within 10 different routes).
  • Out of every character who travels to the former, Samus is the only character to travel to Norfair more than once (whereas she has two rounds and not one on said stage).
• Big Battlefield, Paper Mario, Super Mario Maker, Yoshi's Story, Mute City SNES, WarioWare, Inc., Hanenbow, PictoChat 2, Balloon Fight, and Tomodachi Life are the only stages that do not appear in any character's Classic Mode route in any form.
• Mario fights the most playable opponents in his Classic Mode route than any other character, 23 in total, including Bowser before his transformation into Giga Bowser.
• Ignoring alternate costumes, Hero fights the least amount of variable opponents in their Classic Mode route, with a total of only five different opponents, moveset-wise.
• Mario and Piranha Plant are both tied for fighting the most characters in a single round, with eight each; Mario fights Bowser Jr. and the seven Koopalings, while Piranha Plant fights all eight Inklings.
• Link is the most common opponent for Classic Mode routes. He appears in 18 different routes, mostly in his dark alternate costume.
  • If counting the four routes in which it can be used by Pokemon Trainer, Charizard has the second highest amount of appearances as an opponent, with 17 routes.
• Excluding DLC characters, Snake, Mega Man and Pac-Man are tied as the least common fighters for Classic Mode opponents, each appearing as opponents in only three routes. Ironically, Pac-Man fights both Snake and Mega Man in his own route.
  • Out of these, Pac-Man is also the only one who doesn't face an alternate version of himself within his route.
  • Wolf and Shulk are the only other fighters who face Snake and Mega Man respectively in their routes.
• Excluding Toon Link's route, Diddy Kong may be the most common CPU ally for Classic Mode rounds, for all preceeding rounds of Donkey Kong's route, but Mario and Pit appear in a maximum total of three routes than every other character who's been a CPU ally in Classic Mode routes.
• Young Link is the only fighter who faces opponents only from his own series, including the boss. Excluding their bosses, Lucina, Pokémon Trainer, and Pikachu each face characters only within their own series as well.
• While Pokemon Trainer & Pikachu fight have an alternate version of the latter appear in the background of their routes, and despite Duck Hunt & Marth each fighting Mii Fighters with animal-like costumes, Yoshi is the only character who doesn't have humans for opponents.
• Mario, Yoshi, and Peach are the only characters who face all seven of the Koopalings in their Classic Mode routes.
  • Mario fights the Koopalings, followed by Bowser Jr., in the same order he faced them in Super Mario Bros. 3.
  • Yoshi fights the Koopalings in the same order as in Super Mario World (Yoshi's debut game).
  • Peach fights Bowser Jr. individually, then fights the Koopalings in the same order as in New Super Mario Bros. U.
• Excluding Dark Link as a minor boss considering he's the most common opponent for Classic Mode routes, Yoshi, Jigglypuff, Bowser, and Joker are the only characters who fight a minor boss from a previous game.
  • Out of these, Bowser is the only character who faces a metal opponent rather than a giant opponent.
• Mega Man, Ryu and Bayonetta are the only characters whose Bonus Game occurs earlier than the penultimate battle. Mega Man and Ryu have their Bonus Game in the middle of the route, while Bayonetta's is before the final two rounds.
• Jigglypuff and Bayonetta are the only characters who do not fight a boss. Instead, both characters fight a powerful fighter for the final battle.
• Bowser, Mega Man, and Hero are the only characters who fight a boss outside of the final round. Bowser and Mega Man each fight a boss for their penultimate battles, while Hero fights a boss in the middle of the route.
