Ditto match
Not to be confused with the Pokémon,Ditto.
Aditto match or amirror match (often shortened to justditto ormirror), is a match where both players choose the samecharacter. They are different from other matches in that neither player has an objective matchup or stage advantage over the other player. The name comes from the definition of 'ditto', which means 'the same'. Ditto matches occur frequently duringtournaments, often between top-tiered characters, as they are the most commonly played. Due to the possibility of all players being able to pick the samecostume, the game gives each player different visual indicators. This includes players being shaded differently to be lighter or darker than each other, and elements like the shield and character outline using different colors based on controller port.
Strategies[edit]
Strategies for a ditto often vary greatly from the character's normal strategy. Since both players are using the same fighter against each other, both likely know what strategies the other will use ahead of time. This requires the players to take a different approach when playing. An example would be aMeleeJigglypuff ditto; both players have access to Jigglypuff's strong aerial drift and large, disjointed hitboxes, and neither can be comboed very easily due to Jigglypuff'sfloatiness. If one player attempts to landRest to close stocks out early, the other can easily retaliate with their own and force the game back to a neutral position at worst. Due to this, Jigglypuff dittos disproportionately revolve around theneutral game, with the player that has superior patience andspacing usually edging out their opponent. Another example would be in aSuper Smash Bros.Captain Falcon ditto match; due to Captain Falcon's incrediblecombo ability along with his own vulnerability to combos, the match ends up taking advantage of player flaws more frequently than usual.
A general strategy is to be unpredictable at all times and use experience with a character (knowing combos or recovery strategies) against the other player.Snake is a good example of this; in a mirror match of the two, the players have to use projectiles in such ways to make thestage difficult to navigate for the other player.
Matchups[edit]
Matches in which two players of equal skill use the same fighter should theoretically not favor either player, but this is not always precisely the case, especially when it comes toport priority. The most obvious imbalance regards simultaneous KOs and is overridden in tournaments by the "Suicide Rule". The remaining differences generally have little effect on practical tournament gameplay, though for some characters like Snake the imbalance can be noticeable. Ditto matches are also notorious for weird occurrences. The potential for players to hit each other with the same move at the same time can lead to unexpected interactions and outcomes that may or may not be heavily in favor of one player.
