Multi-Man Smash (組み手, Group Combat) is a Stadium sub-mode appearing in Super Smash Bros. Melee as Multi-Man Melee, Super Smash Bros. Brawl as Multi-Man Brawl, Super Smash Bros. 4 as Multi-Man Smash, and Super Smash Bros. Ultimate as Mob Smash. This sub-mode pits the player against multiple consecutive simultaneous foes, challenging them to defeat as many as possible under various pretenses, while additionally allowing for more characters to be on-screen than allowed under normal circumstances. Though the player has only one stock, the enemy team generally sustains high knockback (moves with high enough base knockback are usually enough to OHKO them), has a low artificial intelligence level, and lacks the ability to perform special moves or grab ledges, making them easy to KO. The mode's difficulty arises from the fact that though individual opponents can be very easy to defeat, it becomes hard to divide one's attention among as many as five opponents at once, making it easy to slowly rack up damage taken over the course of the mode until one or more stray attacks can KO the player. Multi-Man modes take place on Battlefield, and starting with Ultimate, any Battlefield form can be chosen.

In Ultimate, Mob Smash is no longer a Stadium mode, instead located directly in the Games & More menu along with Classic Mode, Training Mode, Stage Builder, Home-Run Contest, and others.

List of Multi-Man modes

Ryu and his Rival in Rival Smash in Super Smash Bros. for Nintendo 3DS.

Six Multi-Man modes are available per game, with Rival mode replacing 15-Minute mode in SSB4, Endless mode merging into All-Star mode in SSBU and 10-man mode & 100-man mode merging into Century mode in SSBU for a total of eight different Multi-Man modes throughout the series.

In Super Smash Bros. 4, as with any Stadium sub-mode, players are unable to use any customizations, preventing players from using equipment to augment their characters' power or bypass the game mode's restrictions. As such, excluding the Mii Fighters, fighters are only allowed to use their default special moves.

  • 10-Man - challenges the player to defeat ten opponents. This is the shortest of all the Multi-Man challenges, usually taking between 10 and 20 seconds to complete for an amateur player, though world records are all within roughly 6 and 7 seconds.
  • 100-Man (Called Century in Ultimate) - challenges the player to defeat 100 opponents, which get tougher as the mode continues. This usually takes a few minutes for players to clear, and can get quite difficult towards the end of the mode. The final enemy to be fought will always sustain noticeably less knockback than the others.
  • 3-Minute - challenges the player to survive for 3 minutes, defeating as many opponents as possible.
  • 15-Minute (Melee and Brawl only) - challenges the player to survive for 15 minutes, defeating as many opponents as possible. Foes get stronger as time passes by. Despite the need for endurance, simple strategies such as spamming a certain move or evading the opponents altogether will generally suffice.
  • Rival (SSB4 only) - challenges one player to defeat more opponents than their Rival (an AI copy of their character) before they are themselves defeated in an otherwise endless match. Rivals respawn after being KO'd. The player's final score is equal to the difference of the number of opponents they and their Rival defeated. This mode replaces 15-Minute mode in SSB4.
  • Endless - challenges the player to defeat as many opponents as possible before being KO'd themselves. It has no time limit nor enemy KO limit, and as such can go on for an indefinite amount of time.
  • Cruel - challenges the player to defeat as many opponents as possible before being KO'd themselves, like Endless mode, but now the opponents have high handicap instead of the player, as well as increased aggressiveness and a high AI level. Additionally, no items will appear. This is unarguably the most difficult Multi-Man mode, as the opponents are immensely harder to KO while the player is also much easier to KO compared to the other modes.
  • All-Star (Ultimate only) - challenges the player to defeat every fighter in the game. The fighters appear in order of their first appearance (based on Japanese release dates), and when all fighters have been killed it loops again from the beginning.

List of Multi-Man enemy teams

Each game in the series features different enemy teams to fight against in Multi-Man modes: Fighting Wire Frames in Melee, Fighting Alloy Team in Brawl, and Fighting Mii Team in Smash 4 and Ultimate.

  • Fighting Wire Frames   - purple-colored male and female wireframe humanoids. Male Wire Frames are based on Captain Falcon, while the Female Wire Frames are based on Zelda. They cannot charge smash attacks, and despite being based on Captain Falcon and Zelda, their attacks also have no fire, electric, or magic effects.
  • Fighting Alloy Team   - metallic fighters based on four characters in the game. Red alloys are based on Captain Falcon, Blue Alloys are based on Zelda and Zero Suit Samus, Yellow Alloys are based on Mario, and Green Alloys are based on Kirby and Jigglypuff. Despite being based on Zelda, Blue Alloys lack magic and fire attack effects. They cannot grab items nor receive giant, tiny or flower status effects. Every 25th opponent fought is spawned as a character, and the final opponent is a palette swap of the player's character.
  • Fighting Mii Team    - Mii Fighters wearing black jumpsuits with a white "M" letter printed on its anterior and two white "i" letters around their limbs. Their skin and facial appearances cull from Miis saved on the player's console, or from pre-loaded/guest Miis if there aren't enough. Despite this, their height and weight are all uniform. They can recover by footstool jumping off each other despite not being able to attack each other otherwise. Every 50th opponent fought is spawned as a giant character, and the final opponent in 100-Man Smash is a giant version of the player's character in SSB4. Every 25th opponent fought is spawned as a character in Ultimate.

Items

For balancing reasons, certain items do not spawn in Multi-Man Melee and Multi-Man Brawl, and only a select few appear in Multi-Man Smash. Additionally, no items will spawn at all in Cruel mode, as well as All-Star Smash in Ultimate.

Trivia

 
Egg Lay glitch
  • Each member of the enemy teams in all Multi-Man modes weigh the same as Mario, except for the Female Wire Frame in Melee, who weighs the same as Zelda.
  • Clearing 100-Man mode for the first time gives the player the opportunity to unlock an unlockable character via a 1 vs. 1 battle if the character has not been unlocked yet: Falco in Melee and Brawl and Wario in SSB4.
    • In Ultimate, due to the game having more unlockable characters than starter characters, the said game is the first installment in the Super Smash Bros. series which does not have an "unlocking an unlockable character" challenge for a reward.
  • The Fighting Mii Team cannot wear hats even if the Miis their appearances are based on have them. They also do not change their facial expressions in battle.
  • The Fighting Mii Team can have varied head shapes, so when inflicted with the flower ailment, it sprouts from the back of their necks rather than from their heads.
  • Prior to version 1.0.4, a glitch in Super Smash Bros. for 3DS allowed players to use Egg Lay repeatedly to increase the size of giant opponents.
  • The final boss of the eShop game Kirby Fighters Deluxe, Team DDD, is modeled after Multi-Man mode, consisting of 61 Mini Dededes, two medium-sized Combo Dededes, and King Dedede himself.
  • In Ultimate, the Dutch name of Squad Strike is shared with the German name of Mob Smash (Multi Smash).
