Spike

A spike is an attack in the ' and ' series that sends enemies downwards. Unlike meteor smashes, spikes cannot be meteor cancelled, making them very powerful tools for edgeguarding.

In Super Smash Flash
Although the How to Play tutorial mentions meteor smashes, meteor cancelling is absent from Super Smash Flash. Therefore, the game only contains spikes.

Due to the instant-KO attack bug, every attack in SSF can spike opponents if they are moving at a specific angle quickly enough. s have the ability of spiking opponents without needing to be affected by the bug in order to do so.

However, getting attacks to actually spike is considerably difficult; although the instant-KO bug is what allows the moves to spike opponents in first place, it also causes said moves to strongly semi-spike opponents most of the time. In order to properly spike opponents with a down aerial, one needs to hit an airborne opponent who is moving extremely slowly, or not at all.

In Super Smash Flash 2
In Super Smash Flash 2, every attack that sent opponents downwards was a spike, until the addition of meteor cancelling in demo v0.8a, where every attack that sent foes downwards became a meteor smash, instead.

Spikes were re-introduced to SSF2 in Beta 1.2.3.1. Players are instantly unable to meteor cancel their knockback if they are flying at angles lower than 240°, or higher than 300°. This means that some moves will only spike in specific situations, i.e moves such as 's forward aerial multi-hits, whose knockback angle and strength depend on the user's current movement speed, and moves such as 's down smash, which deal more than one hit (one of them being a meteor smash), and, due to knockback stacking, may end up spiking opponents who get affected by both hits.

List of spikes by character
The list below only includes moves that can spike without needing to be affected by knockback stacking or other unorthodox situations.

Trivia

 * Before spikes were re-added to SSF2, 's down aerial contained a variable that turned its tipper hitboxes into spikes. The variable did not work, however.
