One-hit KO

A One-Hit KO (or abbv. OHKO) is a very strong hit that can KO the enemy at 0% damage. However, almost all of the so-called OHKOs are highly conditional; they all share the following restrictions:

• The opponent does not tech, DI, momentum cancel, or crouch cancel.
• There is no wall to absorb 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. (due to Stale-Move Negation.)
• Knockback may be insufficient if the attack had been used on a heavy character.
• The opponent is not giant and/or metal.
• The damage ratio is on 1.0 and no handicaps.
• The opponent does not roll, dodge, air dodge, Shield, or Perfect Shield.

The typical rule of One-Hit KO's is knocking opponent's at 0% from one side of Final Destination to the opposite Blast line, resulting in a KO.

Examples

• Roy's almost fully or fully charged Flare Blade.
• Beast Ganon (If the whole Final Smash hits).
• Marth's Critical Hit.
• Wario-Man's almost fully or fully charged Wario Waft.
• Mr. Game & Watch's fully charged Oil Panic absorbing strong projectiles. (Such as three PK Flashs)
• Tabuu's Off Waves (on Normal or higher difficulties in SSE). (Very Hard and Intense in Boss Battle mode)
• Tabuu's Golden Bracket move (Intense difficulty)
• A Side smash done by a Home-Run Bat.
• The Dragoon.
• The first spike on Rumble Falls (easily teched).
• A Pitfall against Wario using the Wario Bike.
• The Ultimate Chimera's bite. (In Stamina Mode, it's not always a One-hit KO).
• Getting hit by a walking Bob-omb while using Fox's reflector in SSB.
• Breaking Jigglypuff's shield. (counts as SD)
• Getting crushed in the Subspace Emissary.
• Suicune's Aurora Beam.
• Deoxys's Hyper Beam.
• Lugia's Aero Blast (only in SSBM)
• Touching Moltres in both SSBM and SSBB can KO at 0%.
• When smash thrown, Electrode's explosion is strong enough to OHKO even Bowser (King Dedede can survive at 0% however).
• Light Arrow, depending on the field size, obstacles, or number of targets hit. (more targets equals less knockback).
• Roy countering a strong attack.
• Corneria's cannon laser shots.
• Ike's stage 8 Eruption.
• If a Hothead is hit by an fire-based attack that does over 30% (such as Ike's stage 7, 8, and fully charged eruption) while it is uncharged, it will OHKO when smash thrown. Any sparks it gives off while traversing the stage at this strength will also OHKO.
• If a Soccer Ball is launched by an extremely powerful attack such as the Home-Run Bat or Marth's Critical Hit, it will OHKO anyone it slams into.
• Lucario's Aura Storm when he's at full power (182% damage).
