A meteor smash (メテオスマッシュ) is a type of attack in the Super Smash Bros. series that strikes opponents downwards, as opposed to horizontally or upwards like most attacks. Meteor Smashes are primarily designed to KO or gimp recovering opponents at especially low damage. With their potential to take a stock earlier than usual, most conventional meteor smashes are somewhat slow to execute or require sweetspotting.
Some meteor smashes are not meant for edge-guarding and are done only to knock opponents into other hits of the attack. Other meteor smashes can damage only opponents that are on the ground, making them impossible to send targets downwards. These are known as unconventional meteor smashes.
In Super Smash Bros. 4, characters that are meteor smashed onto a floor will bounce back up. While this allows certain Final Smashes to incorporate downwards finishers and still result in KOs when used onstage, it also allows players to tech even if they were standing on the ground (Ganondorf's down air is an exception to this). In addition, stronger meteor smashes are now denoted by a unique sound effect upon connection.
As they hit opponents downwards, meteor smashes cause targets that are not in the air to immediately bounce off the ground they're standing on, reducing the knockback received by 20% and thus making such attacks much weaker and less reliable KO moves on grounded targets; if the intended knockback is below a certain amount, it will not even deliver any vertical knockback at all, and instead merely cause flinching and perhaps tripping. As a result, only the strongest meteor smashes (such as Ganondorf's down aerial) are viable KO moves in on-stage situations. Regardless, meteor smashes on grounded targets are one of the few moves in the series (especially Melee) that are unable to be crouch-cancelled.
In games before Super Smash Bros. 4, if a meteor smash connects on a midair target, the victim does not suffer any sort of bounce effect and will stop their fall, no matter how close to the ground/floor they are on any surface that can block their fall. Because of this, they are able to tech from most meteor smashes with solid timing should they be able to impact a viable surface. In Super Smash Bros. 4, even if the victim is in midair, they will now bounce off the ground regardless if they have sustained a notable amount of damage for the proper amount of knockback power, which is needed for some meteor smashes for programmed reasons (such as most Final Smashes).
Despite their reduced power on grounded opponents, the amount of hitstun delivered by a meteor smash is not affected by the knockback reduction, meaning such moves will cause more hitstun than non-meteor smashes with equal knockback. Combined with their vertical trajectory, this results in meteor smashes being excellent combo starters on grounded opponents.
Meteor canceling is the act of instantly negating the downwards knockback of a meteor smash by jumping or using an up special after being hit. In Melee, a meteor cancel can be done 8 frames after the hitlag ends, producing a distinctive wind-cutting sound and a sparkle (the character will also briefly glow white); in Brawl, meteor cancels are not indicated and can only be done after 25 frames (depending on the character, see below), and attempting to jump to meteor cancel before this will result in a 40 frame penalty before the window opens (this penalty does not apply if attempting to use an up special to meteor cancel without making a jump input). Characters can meteor cancel even if they were hit while grounded, though they must have bounced off a ceiling and still be taking the now-downwards knockback to do so.
Meteor canceling does not exist in the original Super Smash Bros. or in Super Smash Bros. 4 (despite earlier claims of it existing in a weaker form), so meteor smashes in both games are functionally equivalent to spikes.
In Melee, a meteor cancel after an up special must have the stick return to neutral or some other non-up position before performing the subsequent cancellation up special. If the stick is left oriented up, a meteor cancel is not possible.
Characters with unusual meteor cancel windows in Brawl
In Brawl, some characters can meteor cancel sooner than others. Most characters can meteor cancel after 25 frames, while others have different values:
With the exception of Wolf, the different meteor cancel windows are justified; characters that rely on tethers (or a sub-par up special in Yoshi's case) have faster meteor cancel windows, while characters with multiple jumps and the ability to glide have slower meteor cancel windows.
A meteor smash is not to be confused with a spike; while spikes also have downwards knockback angles, they are diagonal enough to not be recognized by the game as a meteor smash, and thus cannot be meteor cancelled. Despite this, many smashers use the term "spike" to refer to meteor smashes, with the term "true spike" referring to spikes. Meteor smashes are also not to be confused with a stage spike, where attacks with standard knockback angles can cause opponents to bounce off the underside of a stage and fly downwards, unable to meteor cancel.
Lists of meteor smashes
Not all characters have access to a meteor smash (e.g. Pikachu in the first three games). The characters that can meteor smash and their respective meteor smashes are listed and described here. Some items, such as Moltres and the streams of a Super Scope, as well as the attacks of some bosses, also have meteor smash hitboxes, but they are not listed here. Spikes and semi-spikes, due to their differing properties, are not listed here. This list does not include unconventional meteor smashes.
