Spike

A spike is an attack in in the Super Smash Bros. series and Super Smash Flash series that sends an enemy downwards at high speeds. Spikes cannot be Meteor canceled by jumping while the player is plummeting down. This is because the hitstun from a spike ends on its own, and hitstun from a meteor smashes can be canceled.

In Super Smash Flash 2
Meteor Canceling was not introduced until demo v0.8a, so therefore, meteor smashes in the demos before v0.8a were functionally equivalent to spikes.

Lists of spikes

 * — Down aerial, called the nipple spike due to the top hitbox of his down aerial spikes.
 * — Down tilt spikes when someone gets hit by the sword's tip.
 * — The tip of Marth's down aerial is coded as a spike, but the hitstun is very low which allows opponents to survive it and appear to meteor cancel it.
 * — Her down tilt will spike if the tip of her toe connects with the opponent. This is the smallest spike hitbox in the game.
