More one-hit KOs?[edit]

Can anyone come up with any more one-hit KOs? I could only think of those three. Tomm 18:24, September 16, 2007 (EDT)

Technically, none of these are guaranteed KOs, because Flare Blade and Judgement 9 won't automatically KO someone if they've been used multiple times, and all of them can be negated by a well-placed wall or ceiling. In fact, those two scenarios make the "one-hit KO" description useless, because they're not guaranteed KO moves. WarxePB 20:48, September 16, 2007 (EDT)
Does the new(ish) definition fit it better? (And couldn't think of the name for the power degrading through overuse. >>) Tomm 20:52, September 16, 2007 (EDT)
Corneria's cannon aren't technically One-hit KO, we should state that it hit you multiple times.--Fandangox 20:33, December 15, 2007 (EST)

Extra Condition[edit]

Wispy Woods (the tree from Dream Land) blowing air in a direction could keep the 1 hit KO from happening or a lot more controversially make a lot more moves 1 hit KOs. It talks about the middle of FD as being the rule for 1 hit KOs so i'm sure this won't be a big deal but it may be worth mentioning in the coditions, it's up to you if you want to add it. Lucasthalefty (talk) 08:42, 9 March 2009 (UTC)


I think ALL of these need to be taken off (especially banzai bill) but I want your opinion first...

  1. Various Attacks that normally KO from 60% (such as Ganondorf's Warlock Punch and Ike's Fully charged Forward Smash) when Giant sized can One-Hit KO
  2. Various thrown items or projectiles such as the Unira used between two Pit's both using Mirror Shield right next to it.
  3. The explosion from a Banzai Bill.
  4. Roy's Counter against certain higher-knockback attacks.
  5. Game and Watch's fully charged Oil Panic, with Ness's PK Flash, or another strong projectile.
  6. A forward Smash Attack done by a Home-Run Bat.
  7. Knuckle Joe's finisher.
  8. Suicune's Aurora Beam (Brawl Only).

Kperfekt722 (talk) 03:35, 25 June 2008 (UTC)

Suicune, I have no idea. Super Mushroom/Poison Mushroom or other size/gravity effects should not be considered either. The Great Fox lasers I'm pretty sure count, since even if you get hit by the final shot, it's a KO. But not the Banzai Bill, since it's basically the same as a Smart Bomb. Double-reflecting anything shouldn't really count. But I think a reflected Hot Head should; they're surprisingly powerful. I don't see why Rising Break/Smash Punch should NOT be considered a OHKO. Same with home run bat. That is the ORIGINAL OHKO. Oil Panic is often an OHKO but there's too many variables. - Gargomon251 (talk) 04:17, 25 June 2008 (UTC)

indeed. what should we do? delete them? Kperfekt722 (talk) 04:19, 25 June 2008 (UTC)

Well you could just mention the situational things like Oil Panic and Counter, etc. But completely remove Banzai Bill, the status-change ones, and any DOUBLE reflects. Single reflects are fine, but how often will you REALLY get an item reflected TWICE? As for Hot Head, I'll do the testing. Maybe I only died in one hit from 50%+ damage - Gargomon251 (talk) 06:48, 25 June 2008 (UTC)
Hothead is a no. I also am tempted to test Bumpers; a Smash throw will almost always KO in the 1p modes, but again, I never tried it with 0%. But unless the great majority of characters is OHKOd I won't add it. And I don't think I've ever seen anyone get hit by Suicune EVER, much less at 0%. It's far too rare. - Gargomon251 (talk) 07:32, 25 June 2008 (UTC)

Actually, i found a fully charged hothead doesn't do it on the first try, but on the second attack on the same person (even if they have zero damage due to a heart container) is INSTANT death. I'm deleting electrode and a few others also. Kperfekt722 (talk) 04:07, 9 July 2008 (UTC)


Wouldnt a ton of moves be on that list if their was hanidcapped damage. Any attack could kill and opponent. Zmario (talk) 22:11, 4 July 2008 (UTC)

I think the definition of a One-hit KO as an attack that can kill at 0 percent, with the damage ratio on 1.0, on any part of any stage (with no bouncing off walls). Maxiscool (talk) 22:55, 4 July 2008 (UTC)

Which final destination?[edit]

Can someone please specify which final destination is being referred to in the One-hit KO section?Zixor (talk) 06:27, 8 July 2008 (UTC)

Does it really matter? - Gargomon251 (talk) 08:17, 8 July 2008 (UTC)
Indeed, does it? Anyways, my guess is that it is Melee's because (as far as I know) that one is bigger. KP317 (talk) 21:58, 25 September 2008 (UTC)

Super jump punch?[edit]

Inside a negative zone it does not One Hit KO, you guys adding the damage negative zone does.If one rushes in there quickly before the damage is added then sweetspot the punch it goes higher yes,but nowhere near enough for a One Hit KO. I suggest we remove it as to not confuse people. - Hatake91 (talk) 21:29, 16 July 2008 (UTC)

I don't think it counts if another Luigi does it. After all, one of the side effects from Negitive Zone is drastically reduced attack power. The Luigi using Negitive Zone has to do it. Maxiscool (talk) 22:18, 16 July 2008 (UTC)

luigis little kick taunt thing is a one hit ko in the too. Kperfekt722 (talk) 05:30, 17 July 2008 (UTC)

Thats what I was talking about, its still not a One Hit KO if the Luigi who did use Negative Zone uses Superjump Punch its not a One Hit KO,Where did you get the idea I was talking about Another Luigi using it? - Hatake91 (talk) 17:08, 20 July 2008 (UTC)

When you said "If one rushes in there quickly before the damage is added" I thought you meant if another Luigi runs in there, for some reason it never occured to me that you meant Luigi's opponent waits until Luigi is done dancing, runs in there, and THEN Luigi clobbers him. Sorry. But if that doesn't OHKO, then you should remove it. Maxiscool (talk) 17:22, 20 July 2008 (UTC)

If Luigi who used the Negative Zone delivers a perfect SJP on the ground it is an One-Hit KO. But if it is used in the air, it may not cause instant KO. Xeze (talk) 18:24, 11 August 2008 (UTC)

Ivysaurs U-Smash[edit]

I'm sorry but that is a one-hit KO 90% of the time. Kperfekt722 (talk) 08:26, 13 August 2008 (UTC)

No, it's not. Clarinet Hawk (talk · contributions) 10:57, 13 August 2008 (UTC)
It's a powerful attack, but not a One-Hit KO. It doesn't kill an opponent at 0%. Xeze (talk) 11:01, 13 August 2008 (UTC)
Test it out. On Final Destination, use Ivysaur's U-Smash (Fully Charged) Against Jigglypuff. KP317 (talk) 21:57, 25 September 2008 (UTC)
Yeah, against JIGGLYPUFF. User:JtM/Sig


Ike's neutral B, Eruption is a OHKO isn't it? BEN!

No, it's not, even when fully charged. Xeze (talk) 21:17, 26 September 2008 (UTC)

What stage does it need to be done on? FD? I know it works on some stages. BEN! Yes on Final Destination. And it must work against all characters, or at least, against the majority of the characters. Xeze (talk) 17:13, 29 September 2008 (UTC)

It doesn't when it's fully charged, but it has much more knock back when it's almost fully charged. I have yet to get the timing perfect yet, but I have heard that it can. BEN!

Luigi's Down Taunt[edit]

I'm pretty sure that Luigi's down taunt is not a One-hit KO inside the Negative Zone. But I think it is if used on an opponent who's hanging on a ledge. Xeze (talk) 15:10, 14 October 2008 (UTC)

Technically, that's a Meteor Smash, and I don't think they count as OHKOs. Toomai (talk) 04:16, 12 December 2008 (UTC)

This is going to get grilled but...[edit]

What about multi-hit Final Smashes like Triforce Slash of Zero Laser, I know they hit more than once, but they are one attack? Ike's Best BuddyGreat Aether!

They count too, but none of them are OHKO's. - Hatake91 (talk) 22:21, 8 January 2009 (UTC)

I understand my idiocy here, but Great Aether is an OHKO when done on 75m. But that isn't Final Destination, so never mind.—Preceding unsigned comment added by L33tSilvie (talkcontribs)
Uh... Providing the opponent does not DI, Tech, or anything else of the like, Triforce Slash is a OHKO. Kperfekt BURN!!! Revert That! 07:45, 28 February 2009 (UTC)
As far as I can tell, the nominations for OHKO's in FSs are (in order of likeliness)

Ike's Best BuddyHere, my Friends 18:17, 6 July 2009 (UTC)

I now also move to remove number 9 Judge. I have never seemed to be OHKO'd by it.


On Training mode, I slowed the game down so that I made sure that I hit the 8th stage. The CPU (Yoshi) was at 0 damage, and it was sent very high (higher than the fully charged version) but was not star KOed. I understand how OT may be more reliable, but I'm pretty sure it's not a OHKO. I've debunked claims of OHKOs in the past, such as G&W's #9 and Shiek's final Smash. Anon 00:14, August 27, 2010 (UTC)

Test it in VS. Mode. I didn't see this before I left a message on your talk page, but you must know that moves gain a slight power bonus when completely non stale in Vs. Mode. The OHKO page is based on what are OHKOs in Vs. Mode, not Training Mode. Even in Training Mode, a stage 8 Eruption will OHKO all of the lightweights except for Squirtle and will also OHKO Peach and Ivysaur. Omega Tyrant TyranitarMS.png 06:19, August 27, 2010 (UTC)
Then it's not a true OHKO, no? If it can't KO the vast majority of the cast, then it shouldn't count. Yoshi is not that heavy of a character, yet it did not OHKO him. What should it be listed as? Sir Anon the great 17:43, August 27, 2010 (UTC)
Uh, did you not read what I said? In Vs. Mode, it OHKOs the majority of the characters, and yes, Yoshi is a heavyweight (8th heaviest character in Brawl). Now actually test it in Vs. Mode and you'll clearly see it's an OHKO. Omega Tyrant TyranitarMS.png 17:54, August 27, 2010 (UTC)
OK, I have begun testing it in Slow Brawl on Mario. When I did the nearly charged version, it did 35% (fully charged did 38% and 10% to Ike). Again, it nearly KOed Mario, but didn't. Sir Anon the great 19:44, August 27, 2010 (UTC)
I believe knockback is altered in Slow and Fast Brawls; if so that's not entirely valid. Toomai Glittershine Data Node 20:15, August 27, 2010 (UTC)
Then how do you test the attack out? Sir Anon the great 20:43, August 27, 2010 (UTC)
@Toomai - Speed changes knockback? Could you explain that calculation? I've played Brawl with items on a couple of times and whenever Shadow came out of an assist trophy and used Chaos Control, I took advantage of the slowed down time to KO opponents. While it is slow, KOing an opponent with high damage happens regularly just as it does when the speed is normal.
I agree with Anon in that this isn't a OHKO. Unless we set a standard (X has to be [this] close to/far away from the blastline for an attack to be an OHKO on a Y-size stage), this attack is indeed not a OHKO. By my definition, a OHKO is an attack that can instantly KO an opponent at any damage percentage, be it zero or one hundred, at any part of a stage, unless there is some kind of wall, which, if a character makes contact, can decrease knockback. All in all, should this article be renamed "Lethal attack", since there technically is no such thing as an OHKO if you consider every circumstance? BNK [E|T|C] 21:51, August 27, 2010 (UTC)
We do have a pseudo-baseline - as written on the page it's "being able to KO the majority of characters from the center of Final Destination at 0%". So there's your standard. If you want to test it, then just test it in a normal brawl with no modifiers at all - if you have timing problems, just use a Timer. Slowing characters with a Timer doesn't affect knockback (of that I am certain, whereas a Slow or Fast Brawl I'm not entirely sure). Toomai Glittershine Data Node 22:30, August 27, 2010 (UTC)

@Anon, that's a stage 7 Eruption, didn't you read the message I left you on your talk page and didn't you actually read the Eruption page? A stage 8 Eruption does 39% with vertical knockback, not 35%. Now actually test test this right before calling my informatoin false. You're really beginning to annoy me. Omega Tyrant TyranitarMS.png 05:02, August 28, 2010 (UTC)

After screwing around in random free for alls with my brothers, I actually charged an eruption. One of them was Sonic and ran right into me at 0%. OHKO. The odds of this ever occuring are rare, but I saw it work numerous times in training mode, the waiting room, and random free for alls. I'm just saying that it works for me, even when unintended (and even then, I can't belive it worked).--MegaTron1XD:p 05:05, August 28, 2010 (UTC)

I just sent a replay to Mega and Havoc of Ike KOing a Charizard at 0% with a stage 8 Eruption on Final Destination. They can confirm this and I can assure the damage ratio was at 1.0 and I didn't DI the hit at all. Omega Tyrant TyranitarMS.png 16:52, August 28, 2010 (UTC)

The thing is, that couldn't have been a level 7 eruption. It hit with vertical knockback, and nearly KOed Mario. However, I rest my case at this point as I see quite a lot of evidence against me. Perhaps I have a different version of the game? Anon 17:03, August 28, 2010 (UTC)
That would be a stage 7 Eruption, all stages but the final have vertical knockback and a stage 7 Eruption, while not an OHKO, is still very powerful (it can actually OHKO Jigglypuff on Final Destination). The timing for a stage 8 Eruption is very tight, you have to release it the frame before fully charged. Omega Tyrant TyranitarMS.png 17:39, August 28, 2010 (UTC)
Also, to tell the difference between a stage 7 and 8 Eruption, besides differing knockback, a stage 7 Eruption will do 35% (34% in Training Mode) while a stage 8 will do 39% (38% in Training Mode). This is assuming Eruption is at full power. Omega Tyrant TyranitarMS.png 17:42, August 28, 2010 (UTC)

Master Hand and Crazy Hand's attack[edit]

On final battle in Melee, when I playing classic mode on very hard mode I was confused when Crazy Hand uses his Drill attack it sent Peach upward powerfuly at the start of his attack and it KOs Peach at 0%. Is it true that some Crazy Hand and Master Hand's attack that can OHKO? Luigi540 00:43, 3 April 2011 (EDT)

The Hands have no OHKO attack in any of the Smash games. Either you were not at 0% at the start of the attack or Master Hand was also doing some attack at the same time.
I would like to note, however, that when doing the Master Hand glitch, there are some situations where Master Hand can OHKO to an extent. For example, on Corneria he will be outside of the blast lines, meaning whenever he grabs someone he brings them there with him. Another example would be the Great Bay, where Master Hand can sometimes use his Down Throw to spike opponents through the water. Mr. Anon (talk) 01:06, 3 April 2011 (EDT)

Recent edits[edit]

This is strange. You have tested this with multiple characters, so it can't just be random error here. Can you explain exactly where you were on the stage while you were doing this, because the general OHKO standard is being at the center of the stage. I haven't played Classic mode on intense in Melee in a while, though, so I don't know for a fact. Mr. AnonMatchupUnknown.pngtalk 22:21, 1 October 2011 (EDT)

In Final Destination, I noticed there were few attacks that can KO at 0%. First I played classic mode with Jigglypuff on very hard mode and I noticed that Crazy Hand's start up of his drills sent her upward for a star KO at 0%. When I played classic mode with Luigi, the start up of Master Hand's Jet has a meteor smash hitbox. Since he was on the ground, it sent him upward for a star KO at 0%. I also played classic mode on very hard with Marth. He was being hit by Double Punch and was KO'd at 0%. When I tested with Peach, she hit by Crazy Hand's third poke and got KO'd at 0%. My guess is that only few attacks can KO at 0%. It was Master Hand's grab (up throw), third poke, jet, and drill. Crazy Hand's drill, ram, jet (he attempt to fly into the player), third poke, grab (forward throw), and punch (capable of KOing grounded player). All of their combination attack can KO at 0%. Luigi540 (talk) 22:57, 1 October 2011 (EDT)

Until someone can verify that these Hand attacks aren't OHKOs on very hard, we can have them listed here. I think Luigi540's explanation is sufficient for now. Omega Tyrant TyranitarMS.png 23:03, 1 October 2011 (EDT)

Bike somersault[edit]

Can anyone verify whether this is hacked? - Ceci n’est pas un Smiddle. 07:48, 26 June 2013 (EDT)

I remember seeing this on the Wario boards and being discussed as if it were an exploit, not a hack. Toomai Glittershine ??? The Altruistic 17:25, 26 June 2013 (EDT)
Should it be considered an OHKO? - Ceci n’est pas un Smiddle. 15:29, 28 June 2013 (EDT)
That's a tough one, since it's ridiculously difficult to achieve, isn't supposed to exist, and can't be tested on Final Destination like the article says it should be. Toomai Glittershine ??? The Spectrum 17:29, 28 June 2013 (EDT)
Difficult to achieve and supposed not to exist don't invalidate it, in my opinion. As for the third matter, it could be argued that it produces enough knockback to KO from the center of Final Destination, hypothetically. - Ceci n’est pas un Smiddle. 17:51, 28 June 2013 (EDT)

OHKO in 4 games[edit]

In the trivia, it says that the bat will KO in all four installments of Smash. It should be three; the bat being a one hit ko in SSB4 is unconfirmed and Project M isn't in the Smash series... someone undid mah edit so can anyone clarify this? Qwerty the lord Nessytrewq.jpg 22:18, 5 June 2014 (EDT)

Sakurai's reveal post strongly implies it's just as powerful before, and it's pretty much guaranteed it's going to still OHKO, since you know, that's the gimmick of the item in the first place. Arguing against that seems needlessly pedantic. Omega Tyrant TyranitarMS.png 22:30, 5 June 2014 (EDT)

Subcategory for Smash 4 OHKOs[edit]

Is it safe to add a subcategory for OHKOs in Smash 4, or should we wait? Sakurai has already confirmed at least 1 OHKO (the KO Uppercut) for the game. Rtzxy SmashSig.jpeg Smashing! 21:59, 8 September 2014 (EDT)

I don't mind anyways. We have at least two or three OHKOs confirmed already. Dots (talk) Link OoT Dots.PNG The Non-stick 22:06, 8 September 2014 (EDT)
OK, I'll add it. Rtzxy SmashSig.jpeg Smashing! 22:08, 8 September 2014 (EDT)

One Hit KO/Instant KO differentiation[edit]

Shouldn't things that KO a fighter on-the-spot be separated from attacks that will hit a fighter to the blast line at 0%? Just seems to make sense... ScoreCounter 17:03, 30 October 2014 (EDT)

Seems accurate. They aren't really the same. ---Previously unsigned comment added by you. Or maybe Nutta. 17:07, 30 October 2014 (EDT)

So basically touching an Orne and touching Danger Zones in Smash Run should be moved somewhere else then?--DHD fan (talk) 17:10, 30 October 2014 (EDT)

Yes, alongside getting crushed and the lava from Great Cave Offensive. Should it be its own page, or its own section? ---Previously unsigned comment added by you. Or maybe Nutta. 17:11, 30 October 2014 (EDT)
Well, that's kinda what and why I'm asking, to be honest... I was thinking own section, but after looking at the page's lead paragraph...ScoreCounter 17:13, 30 October 2014 (EDT)
It's own section. It's different enough from a OHKO to deserve a paragraph about it, but too similar as to receive its own page. Just reword a few things and you're done. Simple as that. Rtzxy SmashSig.jpeg Smashing! 17:15, 30 October 2014 (EDT)

Reopening this because some seem to be undecided on this: Reword the header, or create a new page, since these exceptions need to be noted somewhere. ScoreCounter 11:36, 22 December 2014 (EST)

Do any of the Clubberskull attacks OHKO?[edit]

The answer is in the title. I'm more talking about it's more powerful attacks though. They do a insane amount of knockback but I can't tell if they OHKO though. Most of them have that line in the middle of the screen when you straightaway gets hit by them in a zig zag which usually indicates a KO but I don't know what percentage they KO on.--DHD fan (talk) 17:15, 30 October 2014 (EDT)

It's difficult in general to measure how well Smash Run enemies KO because of how the camera works (in addition to the fact that your weight/defense is never normal in that mode). I don't think we can say anything about it as of now. Toomai Glittershine ??? The Brass 17:54, 30 October 2014 (EDT)
Yes, and the Smash run map contains lots of Caves of live. Maybe the Plasma Wisp's energy ball attack can OHKO too in some cases... Mariofan13 (talk) 13:41, 23 March 2015 (EDT)

Little Mac's KO Uppercut?[edit]

The KO Uppercut does not one hit KO. I tested it on Mario from the center of Final Destination, and it didn't KO. Should it be removed? SKMM (talk) 21:23, 5 November 2014 (EST)

More proof: [1]; skip to 1:33. So yeah, I'll delete it. Rtzxy Reflect.jpg Reflect!!! 21:29, 5 November 2014 (EST)

Lucario F-smash?[edit]

According to the page on lucario, in ssb4 lucario's forward smash will ohko when it is fully charged and max aura. However, this attack is not actually listed as an ohko move under the ssb4 sections for the list of ohko moves. Normally I would just add that attack in providing that it actually does KO at 0%, but because the conditions for it to ohko are so specific, would it be appropriate to list this attack in the ohko article? --Icartwright (talk) 10:04, 11 December 2015 (EST)

Well, the conditions for a OHKO are simple: the attack has to be able to kill Mario at 0% in the center of FD. If that one rule is satisfied, then yes, add it. AidanzapunkChristmasSig.pngAidan, the Jolly Space WarriorAidanzapunkChristmasSig2.png 10:14, 11 December 2015 (EST)

Should the Rage mechanic be took into account here?[edit]

In SSB4, something like 9 hammer can ohko thanks to rage. It's such a crucial part of gameplay: every character is effected as soon as they start taking damage. Perhaps if a move becomes a ohko before rage maxes out at 150%... it should be included somehow. RobSir RobSir-sig.jpg zx 00:01, 8 March 2016 (EST)

Isn't 9 already an OHKO? Unowninator (talk) 00:23, 8 March 2016 (EST)

No, it's like the KO punch. It will start killing around 10%, give or take. But with rage, definitely. RobSir RobSir-sig.jpg zx 07:50, 8 March 2016 (EST)

I don't think rage does count for ohko condition unless knowledgeable users like OT said so. Every attack in Smash 4 can ohko are without rage. So no. Luigi540 (talk) 09:03, 8 March 2016 (EST)

Rage should count since taking damage (e.g. for Lucario's aura) is already allowed. Zowayix (talk) 20:29, August 10, 2019 (EDT)

Split into "One-hit KO" and "Instant KO"[edit]

There are several kinds of true "instant KOs" (like the crush) that belong in a separate article from the powerful launching moves listed in this article. Ultimate will be adding several more instances of this. See my full proposal with all examples here. SuperFalconBros (talk) 18:28, 31 August 2018 (EDT)

Inkling's ink[edit]

I tested whether fighters stay inked after eating a healing item, and they do. Seeing as inked fighters take more damage and knockback from attacks (Including those that aren't from an Inkling as I tested this as well and it worked), I was wondering if we could add a section that includes attacks that wouldn't be able to OHKO under normal circumstances but can OHKO if their opponent was inked and has healed prior to the attack, similar to what we did with applied rage in the SSB4 section. Let me know what you guys think. Warriorking98 (talk) 17:45, 18 December 2018 (EST)

I'm tempted to say "only if the attacker is also Inkling". Zowayix (talk) 20:29, August 10, 2019 (EDT)

Whack and Thwack[edit]

They are instant KOs, not one-hit KOs.

But unlike other instant KOs, these 2 can kill at 0%. It's happened to me before. ¿¡Unowninator?! (talk) 12:29, September 29, 2019 (EDT)

As the page states, the one-hit KO move category is for moves that KO at 0% by conventional means. Instant KOs use an effect that just automatically KOs you in place, they don't launch you off the blast lines. 034.png DracoRex, Creator of the Land 12:31, September 29, 2019 (EDT)
Further to this, we define a one he KO as ”an attack in the Super Smash Bros. games with such high base knockback that it KOs an opponent at 0%”. This is an important limitation as otherwise we would have to include moves like Flying Slam in the list. Alex the Jigglypuff trainer 12:37, September 29, 2019 (EDT)
Whack and Thwack very clearly have the same effect as an Orne or a Danger Zone, where it's right then and there; a OHKO is something like Critical Hit or a Home-Run Bat swing, where it's "you get knocked back so hard you hit the blast zone". Aidan, the Rurouni 12:41, September 29, 2019 (EDT)
The Ultimate Chimera and Red Bulborb in Ultimate's versions of New Pork City and Distant Planet stages also cause instant KOs to a fighter at 0%, so they don't count as OHKOs, either. Juju1995 (talk) 12:45, September 29, 2019 (EDT)
