Creepy Blue Eyes

This is the unsettling variety of blue eyes given to particularly degenerate and creepy characters. They tend to be either sort of light and watery, extremely pale, or the type that seems to be too open, to the point where one starts to hope they'll blink soon. This may overlap with Icy Blue Eyes, for certain types of creeps.

No Real Life Examples Please

Anime & Manga

 * Johan Liebert from Monster, and given the kind of man Johan is, they are VERY creepy.
 * There are several blue-eyed characters in Baccano! who are completely off their rocker (Ladd, Lua, Graham, Christopher).
 * Bleach:
 * Gin Ichimaru has very pale blue eyes that he rarely opens. Combined with his pale skin and general aura of creepiness, opening his eyes indicates something nasty is about to happen.
 * Also, Kamui, from in the same vein as Gin, and his is combined with Creepy Shadowed Undereyes.
 * Griffith from Berserk has pale blue eyes, and while he will sometimes deliberately use the Innocent Blue Eyes trope to his advantage, they can turn very creepy when he wants them to.
 * Many Amestrians in Fullmetal Alchemist Brotherhood have blue eyes and blonde hair to emphasize the whole Nazi-expy thing. Most obvious in Scar's flashbacks, where the soldiers' eyes glow blue when they're slaughtering his people.

Film

 * The Big Bad from Beverly Hills Cop had the watery blue.
 * Malcolm McDowell in A Clockwork Orange has blue eyes of the "Grade-A psycho" variety. They look even creepier/cooler now that his hair's turned pure white and his face has gotten all craggy.
 * The vampires and lycans in the Underworld series.
 * In Red Eye, Jackson Rippner has the 'please blink, please blink' villainous variety, to ratchet up the perceived threat to the poor heroine. Being played by Cillian Murphy definitely helps.
 * Scarecrow from Batman Begins has very disturbing pale blue eyes. He is also played by Cillian Murphy.
 * Jim from "28 Days Later" is normally a very nice guy, but could also be the poster-boy for Beware the Nice Ones. When he gets serious, the look in his eyes is genuinely chilling. Since this is another performance by Cillian Murphy, you may be noticing a pattern for Murphy's scary roles.

Literature

 * Jonathan Teatime in Hogfather has one blue eye. With a pinpoint pupil. And he's completely Ax Crazy.
 * The last Kingpriest of Istar from the Dragonlance series of novels is a Knight Templar and is described as having watery blue eyes.
 * Kell Tainer in the X Wing Series is mentioned to have very pale blue eyes, very slightly too dark and narrow to make him look like a madman. If this actually meant anything, the author was fairly subtle about it, but it does seem odd. Hardly anyone in the series has eye colors mentioned.
 * Ter Borcht in Maximum Ride has "pale, watery blue eyes"...and repeatedly states that the flock are overdue to be terminated.
 * Professional Killer Anton Chigurh from No Country for Old Men has eyes that are described as the color of Lapis and are supposedly very unsettling.
 * Roose and Ramsay Bolton in A Song of Ice and Fire are described as having pale blue eyes.
 * The Others/White Walkers and their wights, however, very definitely have blue eyes, and they are very creepy.
 * Kennit of Robin Hobbs's Realm of the Elderlings has very pale blue eyes. He thinks they make him look weak; others find them unsettling.
 * In Empire of the Petal Throne, blue eyes are considered this by definition, due to being highly uncommon and to being associated (at least in legend) with witchcraft. That said, in The Man of Gold subverts the trope.
 * Felix's right eye in Doctrine of Labyrinths is a pale, cloudy blue. Even the people who don't think it's of the occult variety think it's more than a little creepy. Though as it turns out, it's almost completely blind.

Live-Action TV

 * Castiel from Supernatural has the pretty-but-scary variety. Would you just fricking blink, already?
 * In The Vampire Diaries, Damon Salvatore has startling blue eyes, which further adds to his creepiness.

Video Games

 * Alex Mercer from Prototype has very pale, very creepy blue eyes. They're his most noticeable characteristic. Indeed, early teasers and concept art indicate that piercing, creepy blue eyes were part of Alex's design from the first iterations onward. A trailer depicts his irises glinting from beneath his hood's shadow and his shapeshift sequence changing every aspect of his body, leaving his eyes until last.
 * In Blaz Blue, the eyes of Robot Girl Mu-12. Especially in contrast to the red eyes of Nu-13 (who was an Emotionless Girl but became a Yandere if Ragna was about) and the hidden eyes of their predecessor, Lambda-11 (who was treated as an Empty Shell), but most of all, compared to
 * Both and  of the Mass Effect series have these, and in both cases it foreshadows.

Webcomics

 * Williams from Remus has these. It's pretty much his only identifiable facial feature.
