A '''self-destruct''' (abbreviated as '''SD''') is when a character is [[KO]]'d without being hit by an opponent. This usually equates as jumping off the edge, but falls also count as SDs when the stage KOs someone. In [[time mode]], self-destructs subtract one point by default from a player's score; this penalty can be changed to zero or two points in ''[[Super Smash Bros. Melee]]'' and ''[[Super Smash Bros. 4]]''. In [[bonus mode]], the player's [[bonus points|score]] is lowered by 500 points. If characters get defeated by their own [[item]], it counts as both a fall and an SD, making them lose an additional point (Item Self-Destruct worth -1000). [[Friendly Fire]] also accounts for a loss of additional points. The character with the most self-destructs gets the Master of Disaster bonus (-1000), unless they have double or more the SDs of whoever has the second-most (and at least 3), in which case they get Self-Destructor instead (-2000).

Defeating one's own teammate counts as a self-destruct for the attacker and a fall for the KO'd teammate. In ''[[Super Smash Bros.]]'' however, the character that defeated the ally earns a point while the ally loses a point, similar to a regular KO.

In ''[[Super Smash Bros.]]'' and ''[[Super Smash Bros. Melee]]'', a fall counts as a SD if they are KO'd without anyone having been [[KO#KO property|credited with the last hit]] on them, which can occur when:
*The character was standing on the ground, and went beyond a [[blast line]], without being hit off the ground by anyone before the KO.
*The character was hit by a stage hazard and was KO'd, or failed to make it back on stage.
*The character is KO'd by their own item.

In ''[[Super Smash Bros. Brawl]]'' and ''[[Super Smash Bros. 4]]'', however, a SD can only be attained if the KO'd character did not get hit by an opponent during the entire [[stock]] or for three entire minutes, as touching the ground after being hit does not reset their KO property. Therefore, a character can be hit by any attack (or even be [[Footstool Jump]]ed off of), return to the stage, continue to play for a while, and KO themselves, but it will not count as an SD. Players, however, will often refer to any fall that is clearly the player's own fault as a self-destruct, regardless of whether the game counts it as such.

In ''[[Super Smash Bros. 4]]'' characters can be credited for a KO when the opponent self-destructs in a timed 1v1 match.
