Anime and Manga
- The Kirin in The Twelve Kingdoms are so sensitive to blood (prolonged exposure to it can kill them) that merely being in the presence of someone who regularly commits violence (most usually a soldier) can make them feel ill.
- The titular character in InuYasha has used his ability to smell blood many times, sometimes from miles away.
- In Zettai Karen Children, this is one of the more frequently-seen uses for Shiho's Psychometry ability. She is shown, on at least on occasion, to help the police with unsolved crimes (her dad is the Chief of Police) simply by touching various objects related to murders, and then giving them a whole list of details - premeditated or not, identity of the killer, his mindset at the time, ect. She can also immediately identify a dangerous person at a touch. Unfortunately, this has left her constantly exposed to the darkest corners of the human mind since an early age, and as a result, she's frighteningly cynical and downright cold at times.
- In YuYu Hakusho, Yuu Kaito can set up a psychic territory where no violence is permitted - his power detects violence in the sense that it recognizes violent acts and shields the target.
- Mai of Ghost Hunt has periodic psychic dreams pertaining to the case her team is on at the time, usually intimating details about the spirits who have suffered in those locations.
- Naruto gained the ability to detect malice after consuming the nine-tails' chakra and gaining his Golden Super Mode.
- In the movie Hero, the Emperor is able to detect the title character's murderous impulses, shown to the audience as a repeated blast of wind threatening to extinguish the rows of candles separating the two.
- Sgt. Angua has used her hypersensitive werewolf nose to point out suspicious figures and find corpses on many occasions. The price is that the smell of blood is overpowering, hampering her around messy murders.
- The Wheel of Time gives us a kind of person called a Sniffer, who can supernaturally smell that violence has been done in a place, and how long ago. They are found only in the Borderlands, for reasons unknown. Although Sniffers are said to be about as rare/common as One Power users, Hurin is the only Sniffer encountered in the whole book series.
- Anita Blake accidentally touches a neurotic psychic, who starts flipping out about all the blood on her aura.
- Forensic magicians in the Lord Darcy stories can do this.
- Those with the particular Talent for it in the world of Lockwood & Co. can see the sites of violence as particular bright lights, known as "death-glows".
Live Action TV
- As mentioned above, CSI and Bones both use Luminol as a simple way to check for blood at the scene of a crime, which can then be matched to a victim/perp via DNA testing (which, by the way, takes more than a few hours in Real Life). On the above shows, a black light is used to enhance visibility, making the use of Luminol even cooler-looking.
- In the fifth season of Angel Wolfram and Hart had psychics with this capability, and Angel used them to examine a house where a relevant atrocity had taken place years ealier, on the pretext of being potential buyers.
Psychic: The walls scream with the blood of the innocent.
Realtor: I'll be in the car.
- Murdoch Mysteries: Murdoch performs this a couple of times with a(n anachronistic) luminol-like compound:
- In "Dead End Street", he uses it to find blood traces in the culprit's cart months after the cart was used to transport the victim's corpse.
- Murdoch confidently breaks out the sprayer again in "Murdoch Night in Canada". Only problem, he tests this on hockey sticks, forgetting that hockey players don't go easy on each other. The sticks are covered in blood traces, making it impossible to tell which one was the murder weapon.
- Traveller. The K'kree were vegetarian aliens with an acute sense of smell. Any humans who wanted to meet with them had to stop eating meat for several days ahead of time to avoid offending them.
- Villains & Vigilantes adventure Devil's Domain. The Xareon are a race of Plant Aliens. They refuse to accompany the party because they can sense that the PCs eat vegetable matter, which disgusts them (sort of how humans feel about I'm a Humanitarian creatures).
- In Vampire: The Masquerade, committing diablerie (draining another vampire of its life force) left a stain on a vampire's soul that could be read by other vampires.
- In The Elder Scrolls IV: Oblivion, if you have committed murders, guards may greet you with:
You. I've seen your kind before. You've got blood on your hands. Keep your blade sheathed, you murdering bastard, or I'll put you down myself.
- The Protoss High Templar unit in Starcraft has these Stop Poking Me! lines: "Your thoughts betray you." and "I see you have an appetite for destruction."
