Particularly common in Eastern works is the idea that when someone intends to inflict pain or death, their "Killing Intent" can be felt as a slight pressure or chill, even to people unaware of their presence. The effect is amplified if you look into their eyes
, or if they want to hurt you
in particular. Trained and vigilant warriors generally radiate low levels of Killing Intent at all times, and anyone who constantly radiates high
levels of Killing Intent is either evil or obsessed with combat
(and may feel kinship towards heroes who possess it
). There's generally a noticeable difference between "hot-blooded" and "cold-blooded" Killing Intent too. Sometimes this is considered a form of Ki
, or has an effect on Ki.
While most people can only detect Killing Intent subconsciously, people who have enough combat experience (or are just perceptive) can notice it so well that it borders on Spider-Sense
or Detect Evil
. Likewise, some particularly vicious characters hone their Killing Intent to the point where it can leave people nearby paralysed with fear or even inflict hallucinations. In either case, this will be treated as a mundane skill and not a supernatural ability
. Some people will even tell you it's possible in Real Life
While having some degree of Killing Intent is normally required to fight effectively
, sometimes a character will be able to attack without exuding any Killing Intent at all (through Lack of Empathy
, controlling their emotions
or even spacing out while fighting
), making them an unpredictable combatant
or even a Hero Killer
In some works Killing Intent can be used as a rough way to measure Power Levels
, as someone with sufficient willpower to resist an enemy's Killing Intent will necessarily be at least as strong as them
Since it's hard to depict a sixth sense through a visual medium, Killing Intent
is often represented
by Art Shift
towards a more serious style, or even a Battle Aura
(the metaphorical version), though this has become less common over time. When Killing Intent
is considered a form of (or augments) Ki, it can be represented by a non
The Japanese term for this is sakki
(short for satsu ki
), which is primarily used by practitioners of Ninjutsu
; "Killing Intent" is the most literal translation, though it can also be translated to "thirst for blood."

Anime and Manga
- In Naruto most experienced ninjas can explicitly sense killing intent, and using it to paralyse enemies is a recognised strategy (most famously used by Orochimaru). This ability explicitly does not use chakra.
- In Bleach the force of Kenpachi Zaraki's killing intent causes Ichigo to hallucinate that he is being stabbed as he approaches.
- The martial artists in Ranma ˝ can sense if someone is about to attack them. Ranma is so good, he sometimes dodges attacks in his sleep. Unfortunately for Ryoga, his "danger sense" is also affected by his terrible sense of direction.
- In One Piece, this is one of the functions of Haki.
- Zoro does this as well. His "Kiki Kyutoryu: Asura" is said by Kaku to be a illusory manifestation of his killing intent.
- In Lone Wolf and Cub, every half-way decent martial artist possesses this ability.
- Rurouni Kenshin uses this, while leaving it ambiguous whether it's based on Ki or just body language. The only time Kenshin had significant trouble fighting against someone of a (slightly) lower skill level was Soujirou, whose combination of being a Stepford Smiler and super speedster made him both difficult to read and difficult to react to.
- Additionally, swordsmen of high enough caliber generate Battle Aura that can cause minor destruction.
- In the manga version of Fullmetal Alchemist this is how Riza figures out that Selim Bradley is actually the homunculus Pride.
- One of the many appliances of Nen in Hunter × Hunter. It's worth noting that people unprotected by their own aura could potentially die or suffer serious psychological trauma if they were to be attacked by a strong enough killing intent.
- Parodied in Busou Shinki, where Clara becomes alarmed and claims that she's "never felt so much killing intent"... shortly before a letter falls on her head (she's 15cm tall, but still).
- A silly example in One Punch Man, where Asura Rhino's combat instincts cause him to see the protagonist with heavy shading and surrounded by dark flames... but he's still drawn in a simple style and with a baffled expression.
- Martial artists in Angel Densetsu are constantly amazed at being unable to sense Kitano's killing intent. They always assume he is so skilled that he can hide this, instead of realizing he has less anger than an angel.
- In Monster, the eponymous Serial Killer is so evil that he can terrify people just by being in the same part of the building◊.
- In Kenichi: The Mightiest Disciple, every martial artist senses or projects killing intent at one time or another. On at least one occasion, a master-class fighter knocks a Muggle out by projecting killing intent and looking into their eyes.
- Toriko has killing intent manifest as monstrous Animal Battle Auras known as "Intimidations".
- Kenshiro manifests one of these which freaks out a Fang Clan Giant Mook, a nearly feral beast who goes into a panic when he senses Kenshiro's sheer badassery and intent to wipe out the entire Fang Clan.
- In addition, this was used as a final test to determine who would be the successor of Hokuto Shinken. The test involved Kenshiro and Raoh coming face-to-face with a tiger. When the tiger backs away from Ken, Raoh takes this as a sign that the tiger thinks Ken is too weak and then kills him. In truth, the reason the tiger backed away from Ken was because he sensed so much power and killing intent radiating from him in comparison to Raoh that he feared for his own life.
- Nagisa from Ansatsu Kyoushitsu hides his killing intent very well... which is for the best because when people are exposed to his bloodlust, he freaks out trained government special ops soldiers and sends middle-schoolers home in tears with a single (theoretically unthreatening) sentence and a calm smile. For the record, Nagisa is a physically small and unremarkable middle school student in a bottom-rank class, and is so dainty to the point he has been mistaken for a girl several times and he has the strength of a girl.
- Lyrical Nanoha
- In Kung Fu Hustle, Sing is sent to retrieve The Beast near the end of the movie. When he ends up right outside the room The Beast is in, he hallucinates a wave of blood bursting through the door Shining-style.
- In Hero, the emperor keeps a number of candles between himself and any visitors allowed to come within a hundred paces, claiming that the flames are disturbed by "murderous intent" (all of them blowing towards the emperor when Nameless is thinking of killing him, and then blowing in random directions when his resolve wavers). No sort of magical explanation is given for this, and Nameless' unquestioning acceptance of it suggests that he is familiar with the idea, presumably making it a variation of this trope, rather than a separate sort of Detect Evil magic.
- In Full Metal Panic! Sousuke's past as a child soldier has given him the ability to sense killing intent, which he uses to set traps for assassins targeting him.
- This was also used to torment him. One of Mithril's agents would observe him via the scope of a rifle, and find that Sousuke actually got visually agitated when he did this. It's implied that much of Sousuke's misbehavior in school is caused by him sensing the agent's killing intent without being able to tell where it's coming from, causing him to lash out against people nearby.
- Sword Art Online refers to the ability to sense killing intent from monsters in the game as "Hypersense", which may or may not actually exist.
- Dungeons & Dragons 3.5 has the detect hostile intent psionic power. While active you can sense the presence of people with violence on their minds, are immune to surprise attacks (unless the attackers' minds are somehow shielded), and can use the Sense Motive skill as a free action.
- Street Fighter utilizes the Ki-based version as a major element known as the Satsui no Hadou (Surge of Murderous Intent). Akuma is considered a master of this energy and as such fights and kills anyone who faces him. Ryu also temporarily gets possessed by this energy as Evil Ryu, and tends to go further than Akuma. This is an especially present element in the Alpha series and the Ryu Final Manga.
- In the Nasuverse, skilled fighters can do this. In the Unlimited Blade Works route of Fate/stay night Shirou is able to sense that he is being followed by Archer because he is taunting Shirou with his killing intent. When Shirou calls him out on it he is impressed that such an unskilled magus could detect it. Shirou also uses Archer's killing intent to tell from where he is launching his attack against Berserker during their fight in the graveyard, and notes that it's directed at more than just Berserker.
- And then there's True Assassin's Presence Concealment skill, which renders him virtually impossible to find, unless he's preparing to attack a target in which case his own massive Killing Intent betrays him and makes he much easier to find. Though, in all fairness, when this time comes it generally is already too late.
- Angela from Princess Waltz is right there with with the likes of Kenpachi in terms of bloodlust. In many occasion her glare has caused hardened warriors to flinch and even think that they were vomiting blood after being Impaled with Extreme Prejudice just from being 'hit' by it.
- In Vampire Savior/Darkstalkers 3, B.B. Hood, a bloodthirsty Special S-Class Darkhunter, is so malevolent that her stare alone can instill a paralyzing fear into the lower-ranked Darkstalkers of Makai. This same darkness in her heart was what caught Jedah's attention and allowed her to enter his Majigen. Let it be said that B.B. Hood is the Token Human of the cast.
- In Super Smash Bros., while chatting with Otacon, Snake mentions Ganondorf is "giving off a murderous vibe." He's also uneasy with trying to fight him - "even getting close to him makes my skin crawl."
- The Pokémon game franchise has the attack Dark Pulse, introduced in the fourth generation. It's described as "a horrible aura imbued with dark thoughts", and may cause enemies to flinch.
- Early in The Dragon Doctors, the invisible Murder, Inc. assault is detected in advance due to so many people radiating killing intent at the same time.
- As mentioned above, Killing Intent can occur in everyday life, to an extent; i.e. body language, verbal cues, and the way you can just FEEL it when someone is glaring at you.
- According to an article on Cracked, that FEEL stems from being able to "smell" certain chemicals another person nearby is exuding—though it's not so much a smell as something that strikes directly at your mind and instincts, so you won't consciously sense any odors.
