Spike

A spike is an attack in in the Super Smash Bros. series and Super Smash Flash series that sends an enemy diagonally downwards at high speeds. Spikes cannot be Meteor canceled by jumping while you are 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.
