The editor who added this tag believes this page should be deleted for the following reason: Page's appearances don't meet the wiki's standards, list is super outdated, restrictions seem to be super specific and do not agree with the normal usage of the term. One-hit KO is also not an informal term, and could be added as a quick tidbit in the KO page.

One-hit KO

The most notable one-hit KO: a smash attack with the Home-Run Bat.

A one-hit KO (abbreviated OHKO), also known as hit KO or hit kill is an attack property in Super Smash Flash 2 which, as the name suggests, can KO opponents in one hit even if their damage is 0%. 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:

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.
