Team Battle is a Versus Mode setting present in all games of the Super Smash Bros. series. As the name suggests, players (whether human or CPU) fight alongside others on their team, against the opposing team(s). Team Battle can be toggled on and off in the upper left-hand corner of the character selection screen by selecting the word "Free-for-all" in Smash 64, or the word "Melee"/"Brawl"/"Smash" in subsequent games.
A team battle can contain red, blue, and green teams. Prior to Super Smash Bros. 4, characters are required to use alternate costumes matching their team color; if two or more players are using the same character on the same team, they will be differentiated by a lighter, darker or more darker tint. In Smash 4 and Ultimate, a character's allegiance is instead indicated by a colored outline. This is so that the player can use any color costume of their choice for their character. The following team setups are possible:
Additionally, when playing an 8-Player Smash in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate, an additional team color, the yellow team, can be selected. With a maximum of eight characters that can participate in a match, further team setups become available, bringing the total number to 41. The setups done with 4 or more players are:
Since team battles are a regular type of Versus Mode, the usual options of Time, Stock, and Coin Battle matches can be selected, along with Special Smash rules as well. In Time and Coin matches, the score (or coins collected) of each team is the combined score of its members and if multiple teams have the same total by the end of the match, then Sudden Death will occur between all members of the tied teams. Stock matches are played in essentially the same manner; each player starts with a set number of lives and the objective is to deplete the stock of the opposing team(s). However, in Team Stock matches there is a feature known as Share Stock where, when one player on a team loses their last stock and has a teammate with two or more stocks, the fallen teammate may borrow one of their teammate's stocks and re-spawn as usual.
With the default setting, members of the same team cannot attack each other. However, turning on Friendly Fire (or Team Attack) on the options screen will allow players to damage their allies. This can lead to techniques such as easily using Mr. Game & Watch's Oil Panic move, giving Kirby a copy ability using Inhale, healing Ness or Lucas with PSI Magnet, or hitting a recovering ally with a low-knockback projectile, allowing them to reuse their up special move after becoming helpless.
Team battles are also available when playing With Anyone online. This requires four players, who are randomly split into red and blue teams for a two-minute time match with Friendly Fire disabled.
In all games except Smash 4, all members of the winning team will perform their victory poses simultaneously. In Smash 4, only one of the characters (the player with the highest score/stock count) will perform a complete victory animation and even then, only one of their animations can ever play, usually being the least special effects-heavy (Mewtwo, for example, can only use the victory animation where it turns its head towards the screen after facing away, and can never use its other two). In Ultimate, if Joker poses in front, no other team members will appear. Furthermore, if a solo player wins a Team Battle, the character will perform his or her victory pose, as in a regular Free For All match.
In Ultimate, players have the option to toggle whether their teammate is translucent or not in Local Wireless and Online battles, so that they can focus more on their battle, not the other teammate.
