One-hit KO

A one-hit KO (abbreviated OHKO), also known as Hit KO or Hit kill is an attack which, as the name suggests, KO's opponents in one hit when their damage 0% and if the victim's flight path is not obstructed. As such, they are very powerful moves and most have to be charged. Self-destructs do not count as OHKOs. In order to acknowledge the attack was a OHKO, it has to share the following restrictions:


 * The opponent does not tech, DI, or momentum cancel.
 * Knockback may be insufficient to KO at 0% on very large stages (e.g., Devil's Machine, Crateria).
 * Knockback may be insufficient to KO at 0% if the attack had been landed previously (due to stale-move negation).
 * The opponent and user do not have any modifiers such as being giant, tiny, or metal.
 * The damage ratio is set to 1.0 with no handicaps.

In Super Smash Flash, there are no OHKO attacks, as hitboxes have a constant, per-frame damage output rather than a single set value. However, instant-KO attacks are commonly erroneously referred to as OHKOs regardless.

Examples

 * Home-Run Bat's smash attack
 * 's Puff Up at the moment it utters its name and begins deflating, it has an abnormally large hitbox.
 * 's Blue Falcon.
 * 's Critical Hit.
 * 's Random Encounter at the moment it conjures the "Flare" spell on the screen.
 * The Cherish Ball in Event #36: Gotta Cherish Them All.
