Versus Mode (or VS Mode as styled in Super Smash Bros.) is a multiplayer mode that enables players or computer players to fight against each other or in a variety of settings. Versus mode appears in all Super Smash Bros. games. The characters can participate in a variety of battles, including Free-for-alls and team battles. The players can also set the rules for the battle including the amount of time, the amount of stock, the items that can be used, handicaps, and the stage that the battle will take place on. The players can also choose settings for the computer players including computer players' levels. Some of these features, however, have to be unlocked in order for them to be used.
Called VS Mode, players (up to 4) can play a Time or Stock match. It can be a Free-for-all or a Team Battle.
- VS Start - Takes players to the character select screen.
- Rule - Players can set the rule, either Time or Stock.
- Time/Stock - Players can set the Time if it's a timed match, or the amount of lives each player has if it's a stock match.
- VS Options - Players can adjust some options. They can set the Handicap (on, off, or auto), Team Attack (on or off), Stage Select (on or off) Damage ratio (they can choose a percentage), and, if unlocked by playing 100 VS modes matches, set the items on or off with Item Switch.
Versus mode in Melee is an expansion to the one in Super Smash Bros. The players can now choose a wide variety of options and different styles of battling. The players can also play in a series of tournaments. The c-stick can be used for attacks, unlike in story mode.
 List of playable modes
- Melee -- This is the basic multiplayer mode.
- Tournament Melee -- Allows the player to set up a tournament with up to 64 players.
- Special Melee -- Players can choose from the following options:
- Fixed-Camera - In Fixed-Camera mode, the camera is fixed and does not move around. The whole stage will be seen on the screen.
- Giant Melee - In Giant Melee mode, all the characters are big, similar to the giant characters that are fought in Classic mode. The characters will have a harder time to KO their opponent, but they will fall faster and the distance of their jump will decrease.
- Invisible Melee - In Invisible Melee mode, all characters are invisible, similar to Fox and Falco in the event match Slippy's Invention. Unlike the affects of the Cloaking Device though, the characters can take damage in this mode.
- Lightning Melee - In Lightning Melee mode, the movement speed of the characters will increase.
- Single-Button - In Single Button mode, the only controls that can be used in battle are the A button and the control stick. The use of the B button is disabled for every character in this mode. The characters can still jump however by tilting the Control Stick up.
- Slo-Mo Melee - In Slow-Mo Melee mode, the movement speed of the characters will decrease.
- Super Sudden Death - In Sudden Death mode, each of the characters will have 300% damage. If a character dies and still has remaining stock, then their damage meter will return to 300%.
- Tiny Melee - In Tiny Melee mode, all the characters are small, similar to the affects of a Poison Mushroom. The opponents in Tiny Melee will be easier to KO but they will also have a greater recovery distance.
- Rules -- Players can adjust the rules of matches in this menu.
- Names -- Players can enter names for gameplay here.
 Action Replay uses
With the introduction of the Action Replay and the debug menu, the players can further customize their battle more. They can choose the size of the characters participating in the battle, the different colors of the characters, and other additional settings. The debug menu also allows the player to choose certain stages that normally the game does not allow them to play on. These stages include the Adventure Mode stages, the Trophy Tussle stages, and stages that do not appear in the game at all. The players can customize the computer players actions during battle also. For example, one computer player can be set to just stand on the stage while another computer player can be set to only pick up items.
In Brawl, this mode is called Group.
 List of Playable Modes
- Brawl - This is essentially the same as Melee's, but players can still make it Sudden Death without entering Special Brawl by manually changing the Handicap - This can make it easier to unlock many Challenges, since Special Brawl does not keep records.
- Tourney - Again, this is more or less the same as Melee's Tournament Melee.
- Rotation - The winner out/loser out modes from Melee's Tournament Mode, now in its own mode, separated from Tournament.
- Special Brawl - This is much like Special Melee, only with more combinations and options.
- Rules - This allows players to set the rules such as time, stock, etc.
- Names - Allows players to add, delete, or modify a screenname.
