One-hit KO

A One-Hit KO (or abbv. OHKO) is a very strong hit that can KO the enemy at 0% damage, but basically all of them are highly conditional, all sharing the following restrictions:


 * The opponent does not tech, DI, or crouch cancel.
 * There is not a wall to block the knockback.
 * Knockback may be insufficient on very large stages (e.g. Hyrule Temple, New Pork City, 75m)
 * Knockback may be insufficient if the attack had been used previously.
 * If the attack is not Shielded.
 * The opponent is not giant and/or metal.
 * The opponent does not Perfect Shield.

The rule of Final Smashes as One-Hit KO's is if they can kill opponent's at 0% from one side of Final Destination to the other and resulting in a KO.

Examples

 * Roy's fully charged Standard Special Move, Flare Blade.
 * A forward Smash Attack done by a Home-Run Bat.
 * Getting eaten by the Fish on Summit or a Bulborb on Distant Planet. (This is not technically a "hit"; rather, the victim is trapped and dragged off-screen.)
 * The Ultimate Chimera's bite. (In Stamina Mode, it's only sometimes a One-hit KO.)
 * Corneria's cannon laser shots. (Multiple Hits)
 * A Pitfall against a Wario using the Wario Bike.
 * Marth's Critical Hit Final Smash.
 * Wario-Man's fully charged Wario Waft.

 * Getting crushed in the Subspace Emissary.
 * Getting hit by the bow/front of the Pirate Ship.
 * Getting hit by a walking Bob-omb while using Fox's reflector. (only in SSB)
 * Jigglypuff when its shield breaks. (This is not technically a "hit" either; rather an SD)
