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 One Half 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.
- Present for one moment of Jo Jos Bizarre Adventure, when LisaLisa is about to fight Cars, and notes that she can't detect his Killing Intent. Despite his earlier claims, he never intended to fight her fairly for the Macguffin, and instead has a mook ambush her mid fight while he hides, so he can attack her from behind, claim the Macguffin, then sic his zombie army on Jojo.
- 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 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.
- For a split second in Murciélago, right before Kuroko gets serious with fighting Yukari, Yukari sees a vision of a multi-armed skeleton tangled around her with a scythe around her neck and Kuroko's trademark giant tongue sticking out of its mouth.
- 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, Sakaki has blown away an entire room of people. And with discipline level fighters it can be used to make the opponent lock up and break their focus.
- 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 Assassination Classroom can freely intimidate or paralyze his opponents by emitting killing intent. He once used it, along with a single (theoretically nonthreatening) sentence and a calm smile, to send middle-school bullies home in tears; he's also used it in combat to scare the living daylights out of elite, trained government special ops soldiers. For the record, Nagisa is a small, kindhearted, fairly unremarkable middle school student in a bottom-rank class, and is so physically dainty that he's been mistaken for a girl several times. It should be noted that his killing intention is more of a natural talent. It is commented that he is born with talent at the wrong era. Had time been different, he would have been an assassin without equals.
- Lyrical Nanoha
- In Magical Record Lyrical Nanoha FORCE, when the Special Duty Section 6 are arresting Hades Vandein, his killing intent is so strong that everyone sees a hallucination how he slices Teana down. And this guy always pretends to be an innocent citizen.
- Chapter 45 of Magical Girl Lyrical Nanoha ViVid has Micaiah deliberately emanating this even though she's just attacking with a practice sword so she could bring out the depressed Sieglinde's Black Jeremiah side as a lead-in to her pep talk for the latter.
- Deconstructed in Psycho-Pass. Having a Lack of Empathy is illegal, and can lock you out of most jobs... but if Lack of Empathy upgrades to Killing Intent, the cops gain instant authorization to use lethal force with no repercussions or oversight. And an adrenaline rush counts as Killing Intent, regardless of why you're having an adrenaline rush, which often leads cops to execute the people they just saved from dangerous murderers.
- 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 the live-action adaptation of Rurouni Kenshin, Jin-e can stop people from breathing by looking into their eyes. He explicitly states that it's not supernatural, despite the fact that it can supposedly only be broken by killing Jin-e.
- 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.
- In Overlord, Sebas can control his Killing Intent with incredible strength and precision, to the point where he can stare into a group of hardened warriors and reduce one of them to a gibbering wreck without alerting the others. Normal people exposed to his Killing Intent could literally die of fright. At one point Sebas even uses this as a form of Training from Hell, teaching Climb a "mental overclock" ability by having him experience what it's like to be a hair away from death.
- Lina Inverse of Slayers has been known to use this to tell when somebody's sneaking up behind her in a fight. Gourry and Zelgadiss may also be capable of it - they've been known to react to attacks they couldn't have seen coming.
Live Action TV
- In one episode of Lie to Me, the Lightman group try to use their observational abilities to find an assassin by detecting his or her Killing Intent. The nature of the Lightman group's abilities means that they have to see the person's face for detection.
- Played with at one point. Lightman thought someone had murderous intent and was planning to kill someone else, but it was actually suicidal intent. They managed to stop her her before she goes through with it. Just because you have killing intent doesn't mean you're planning to kill another.
- In Star Trek: Deep Space Nine, Worf once stated that Klingons can see murderous or violent intent in a person's eyes.
- 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.
- In Higurashi: When They Cry, Keiichi refers to being able to feel (or not feel) "murderous intent" and sometimes uses that to decide if someone is trustworthy.
- Killing intent is actually the entire reason your attacks damage monsters at all. As a result, bosses in a No Mercy run tend to be One Hit Killed. Conversely, in a Pacifist Run, when Undyne challenges you to a rematch during her "date", you'll deal only 1 damage whether you use the "Fake Hit" command or Fight her for real, because to even get to this point you have to go out of your way to never kill anyone.
- Monsters seem able to pick up on your killing intent pretty easily. Despite the fact your appearance doesn't change at all whatever run you're doing. Some people will comment on the aura of malice and even start mistaking you for a monster.
- 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.
- Ever been walking along and all of a sudden you feel the hair on the back of your neck start to stand, or you feel a twinge in your gut, you look around and realize that a person or an animal is staring at you? You may not see, hear, or smell anything consciously, but your subconscious mind still picks up on these cues and reacts to them.
- People in RL police/intelligence surveillance and military reconnaissance/sniper operations have to be careful not stare too hard at their targets, as they can sometimes feel people's eyes on them - not to the point where it will cause them to freeze up or from a half mile away, but enough to let them know they are being watched. This can result in blown ops, which in hostile territory is especially a bad thing.
