This is part of an effort to split tropes off of Mismatched Eyes.
An unusual physical trait that ties two characters together. The physical trait can be anything from heterochromia, unusual hair colours, deformities and other odd traits. It could something that's passed down from one generation to another. These traits can be used to identify twins, possessed, clones, or a once unknown connection between two people that indicate they are related.

Related to Family Eye Resemblance when the eyes shows a familial relationship. See also Shared Family Quirks for when family members share similar behaviors or personalities and Mark of the Beast when the trait is a sign of possession.

  • Nenene and Toki from Code:Breaker both have one blue and one brown eye. This almost gets Nenene killed when fire controller Oogami mistakes her for his despised teammate Toki who is Nenene's long-lost brother. Nenene does not seem to notice the resemblance, even when Toki is standing in front of her while Sakura says "This is your brother!"
  • In Fullmetal Alchemist, the fact that Ed, his brother Al, and their father Hohenheim all have gold eyes and gold hair (not blonde, gold) is an important plot point, as it marks them as ethnically members of the lost Xerxes civilization. Hohenheim is an immortal survivor of the apocalypse. The first anime missed the memo and gave Al blue eyes, but it still mostly works.
  • The Count D from Pet Shop of Horrors has heterochromia, one eye being purple and the other, whom he hides under his hair, is golden. In the manga, it's explained that this is meant to be representative not only for his non-human nature, but also for his inheritance: his father and grandfather have golden and purple eyes, respectively. Since each one has a very different personality, and D has personality traits from both, his heterochromia symbolizes this dual nature.
  • Rozen Maiden: Suiseiseki has red and green eyes, and was originally nicknamed "Boatlights-chan" by fans before she became known as simply "Desu". Her twin sister Souseiseki, introduced later, has the same eye colors but reversed. Appropriately, they are foils for each other.
  • Luki and Noki from DOGS Bullets And Carnage have very weird eyes (gold with a black iris, black with a gold iris, with the actual which-eye-is-which swapped between twins). They're enfants terribles.
  • Big Bad (of at least one arc) Rido Kuran of Vampire Knight has one blue eye and one crimson eye, a trait that shows up in the people he possesses. This is the first clue to Rima Touya that something's not quite right about Shiki...
  • In Claymore every claymore warrior for the most part looks human, however their one distinct feature, least before they start tapping in their Yoma powers, is their silver eyes. In one episode the main character, Clare, who's a claymore is task with hunting down a Yoma in a city that doesn't allow claymores. To get into the city she takes a pill that limits her powers but make her appear human just by turning her eyes brown.
  • Vivio from Magical Girl Lyrical Nanoha Striker S has red and green eyes because the person she was cloned from also possesses those features.
  • In Gurren Lagann, some character's pupils (specifically: Lord Genome, Kittan, and Simon) take on spiral form to indicate their mastery of the Spiral Energy.
  • Misaki Shokuhou from A Certain Magical Index has stars in her eyes. The same stars appear in the eyes of those who she's using her mind control powers on.
  • Certain ninja clans in Naruto will have this. Most consistent are the Hyuga, all of whom possess white eyes called the Byakugan. Other examples include the Uchiha and their Sharingan, and the overweight Akimichi clan.

  • In one film version of The Hound of the Baskervilles Sherlock Holmes realizes that Stapleton is a member of the Baskerville family because both he and a portrait of patriarch Hugo Baskerville have webbed hands. (In the original novel, Holmes points out that Stapleton is facially a dead ringer for the portrait of Hugo when you block out of view the antiquated clothing Hugo is wearing.)
  • X2: X-Men United: Jason Stryker has differently-colored eyes, as does the illusory little girl he creates.

  • On Kyle XY, one of the first things that tips Kyle off to Jesse's connection to him is the fact that neither of them have a belly button.

  • The horribly inbred Martense clan from The Lurking Fear by HP Lovecraft all have this as a distinguishing mark. They have brown-and-blue eyes apparently. This is the tip-off that the swarm of Humanoid Abominations haunting the area actually consists of their offspring.
  • All the clone "shatterlings" of Gentian Line in "House of Suns" by Alastair Reynolds have one green eye and the other a "wintery jackdaw blue", since they're all male and female "facets" of Abigail Gentian. it is noted that since they have a bit of leeway from Abigail's exact appearance, in some shatterlings the mismatched eyes are toned down so much as to be unnoticeable
  • One Goosebumps book has the main character's best friend be a girl with heterochromia. This becomes a plot point when she mysteriously disappears and he starts seeing a dog with Mismatched Eyes around the neighborhood.
  • The generational sagas by author Edward Rutherfurd often use physical genetic quirks, such as webbed digits or Skunk Stripe hair, to illustrate a bloodline's continuity down through the centuries.

  • The play Redwood Curtain is centered on a young Vietnamese girl who was adopted by an American family. She has "eyes like a husky dog" (one blue, one dark). When she meets a homeless Vietnam vet who has similarly mis-matched eyes, she starts wondering if he could be her biological father. He's not, but he knows who is.

  • Mortal Kombat Armageddon: The protagonist of Konquest Mode, Taven, is shown to be related to his brother and antagonist Daegon by a dragon tattoo on their faces, which are inverted mirror images of each other.
  • In Tales of Graces, this is a sign that Lambda is inside somebody's body. It happens to Richard and later Asbel, and this carries into Tales of Graces F. When Lambda is inside Richard, his other eye is red, but when it happens to Asbel, it's actually purple, signaling that Lambda has a different relationship with Asbel than Richard.
  • In Devil May Cry 3, Lady and Arkham and Jester both have one blue and one red eye. This serves as a visual clue that they're father and daughter.
  • Iris and her twin sister also named Iris from Rune Factory both have green and red eyes. They used to be one person but were magically split into two entities.

  • Christian Weston Chandler in Sonichu has heterochromatic eyes, though it's not at all striking. It's a feature of his Evil Twin (with inverted colors) and his Chris-Chan Sonichu form, too.
  • When Abel of Dan and Mab's Furry Adventures first enters the Succubus and Incubus Academy, he attracts interest because of his heterochromia and the dual batlike/birdlike nature of his wings. Both of these are traits of Quoar and his elusive clan members.
