One hit knockout

A One hit knockout (OHKO) is a term used for character attacks that, if successful, knock the other player out instantly.

These are usually achieved by setting the opponent's health to zero if the attack connects, resulting in an instant kill that cannot be survived regardless of health or defense level.

This is widely discouraged throughout the M.U.G.E.N community, unless the attack is originally part of the movelist of a character which is being ported to M.U.G.E.N, such as those in Fist of the North Star or Guilty Gear.

"Untrue" one hit knockouts
Certain attacks aren't true one hit knockouts, but cannot be survived by normal characters.

These attacks usually deal a fixed amount of damage, usually a very high amount, that will easily deplete 1000 to 2000 life on most characters, even with significant defense multipliers. However, by artificially setting the character's defense or health to a very high level, it would be possible for the character to survive the attack.

An example is Metool's Giant Metool drop, AKA, and 0WN3D, which does 9000 damage, a possible reference to the "Over 9000" fad. Most overpowered Dragon Ball Z characters who have energy waves that deal damage at a constant rate instead of one extremely strong blow.

Infinite attacks that, unless halted, put the opponent into a constant hit state loop can also be classified as untrue one hit knockouts. An example would include Psyqhical's Energy Pillar in the corner.
