Esdese of Akame ga Kiru! is one of the single most powerful human beings on earth by pure strength alone. Add to this a special weapon called a Teigu contained in her body that gives her complete control of ice and the ability to freeze anything and everything, including time and space, makes her an enemy that requires an entire army just to pose a threat to. She is also a complete and total sadist, who delights in causing terrible pain and suffering to anyone and anything.
Kuzan, a.k.a. former Marine Admiral Aokiji, possesses the power of the Hie Hie no Mi (Chilly-Chilly Fruit, or Ice-Ice Fruit). Aokiji's Devil fruit allows him to create, control, and transform into ice. His powers are such that he can freeze a chunk of ocean (complete with sea monster) with seemingly little effort and with a guarantee that it'll last one week. He's also all-but-immune to physical attacks as, while they can shatter his icy body, he can immediately reform it.
Touya of YuYu Hakusho is a demon ninja with mastery over ice. When he went under Genkai for some Training from Hell, he became powerful enough to freeze a battlefield. Seiryuu, one of the Four Saint Beasts (and also, ironically, The Dragon to Big Bad Suzaku), also had ice powers, but he was a drop in the bucket compared to Touya. There's also Yukina, actually an ice maiden.
Yukino Houjou of Gate Keepers, the immortal and ridiculously powerful user of the Gate of Ice and Snow.
Two in Bleach: Toshiro Hitsugaya (Hyourinmaru, translation: Ice Ring) and Rukia Kuchiki (Sode no Shirayuki, translation: Sleeved White Snow). If the name of her Zanpakuto is indeed meaningful, the lieutenant of the 4th Squad, Isane Kotetsu, may be like this too (her Zanpakutou is Itegumo, translation: Frozen Cloud).
Cygnus Hyoga and Kraken Isaac from Saint Seiya, and so is their teacher, Aquarius Camus (also, the Crystal Saint in the anime).
Extra fun: in the anime, the Crystal Saint explains to Hyoga how to manipulate temperature: slow down the electrons and stay away from the nucleus.
Tokiya Mikagami in Flame of Recca has a lot of water-based attacks, but that's mostly his low-level techniques. His high level technique includes ice-based attacks. On the other hand, his master, Meguri Kyouza, and his fellow Hyomon Ken practitioner, Kai, goes to the extreme and only uses ice.
Maria of Mermaid Melody Pichi Pichi Pitch plays up the ice angle with all she's got; she's stuck up, cruel, and often described as "cool" or "cold". While the rest of the Quirky Miniboss Squad to which she belongs harbours genuine Mad Love, her interest in her boss is purely physical and she doesn't really care whether he loves her back or not, even if she is a childhood friend. She also enjoys turning people into Human Popsicles and specifically targets lovers because warm feelings seem to physically hurt her.
Urusei Yatsura had Queen Oyuki, who was a fairly nice person, aside from occasionally freezing everything around her in a huge block of ice.
Mannen from Prétear specializes in freezing things, with his element listed as "cold" — "water" is a separate element controlled by a different Knight.
The same listed trainers in Pokémon in the anime, as well as Ash's disobedient Snorunt in one season.
Mizore from Rosario + Vampire fits within these bounds. Based on a snow woman from Japanese mythology, she has a variety of ice powers, including making her limbs (and hair) into ice, blizzard attacks, and ice clones. Her mother, Tsurara, as well.
JoJo's Bizarre Adventure had a couple of ice stand users. The first one was a falcon named Pet Shop in Part 3 who could create ice formations in midair and control them. The second was Ghiacchio from Part 5 who could create an absolute-zero field around himself and control ice within his range.
In Part I Dio Brando used his vampiric abilities to drain heat from his victim's bodies, freezing their blood in the process. This was an effective counter-measure against the vampire killing Ripple which relies on breath control and the flow of blood. Jonathan had to set his own fist on fire to hit Dio with a Ripple.
Mahou Sensei Negima! has Evangeline, whose ice magic can reach ice-age like states, including an ancient Greek spell that covers a 150-square foot area in absolute zero temperatures. It translates to something like "Eternal Glacier" and "End of the World".
The spell has two different endings and its effects vary based on which ending is used. The "Eternal Glacier" ending simply encases the target in a solid block of ice, while the "End of the World" ending actually turns the target's body into ice and shatters it.
Vampire Knight has Hanabusa Aido, a vampire with ice based powers. He's actually a pretty cool guy most of the time.
Fullmetal Alchemist: Brotherhood gives us Isaac McDougall, the Freezing Alchemist. However, he's been shown to use not just ice, but high-pressure water, steam, and his own blood. His favored mode of killing is to freeze or boil all the water in a person's body.
Guyver has Bio-Freezer, a Lost Number who can shoot chilling air that can freeze a lake in a few seconds. This has come in handy for the good guys a few times, but since he has otherwise below-average abilities for a Zoanoid and his freezing power leaves him exhausted whenever he uses it, he usually ends up being Overshadowed by Awesome. Eventually, he performs a Heroic Sacrifice, allowing himself to be absorbed by Aptom in order to save his life. Aptom then gains his powers.
Nobara Ibaragi in Gakuen Alice has the Alice (magic power) of Ice.
November 11 in Darker than Black sort of counts. His ability is to drain heat from anything he touches; cells burst and water turns to ice almost instantly. He can't make ice out of nowhere, however, and needs something to conduct the freeze effect to be of much use.
Akashikibu from Blazer Drive (coincidentally, she feels true beauty should last forever and manipulates a person with the same face-concealing bangs as Deidara).
Snow of MÄR uses ice-style ARMs (and one water-themed, eventually). Her real-world counterpart is named Koyuki.
She's also weakened in a desert area, brought to the point of exhaustion in a volcano area, and hinted to be strengthened in an ice field.
Free from Soul Eater uses ice magic. But after centuries imprisoned by the witches, he's a bit rusty and does things like encase himself in blocks of ice and fall into the Thames (he was trying to use the ice to avoid falling). Being nigh-invulnerable, this isn't much of a problem for him.
Metalgarurumon in Digimon can fire ice missiles and freezing breath (the latter oddly called "Metal Wolf Claw").
He's got ice and destructive versions of all his attacks, all of which are prone to being labeled "Metal Wolf Claw" or "Ice Wolf Claw" depending on how the writers are feeling (though the original name of the attack is Cocytus Breath, named after one of the five rivers of the underworld in Greek Mythology). Also, there are a number of ice-related Digimon and ice versions of non-ice Digimon. Contrary to popular belief, Gabumon is not one of these - the blue energy he fires was once used to start a fire.
Seadramon's main attack is freezing breath, which he used to encase Garurumon in ice in his first appearance. MetalSeadramon also has a freezing breath attack, at least in the non-Adventure material (there he has fire breath).
Tomoki Himi from Digimon Frontier possesses the Human and Beast Spirits of Ice, which allow him to transform into Chakkmon, a polar bear on skis, or Blizzarmon, a twin tomahawk wielding yeti.
Tomoki is also one of two members of the team whose nameinvokes his element - the "Hi" in Himi uses the same Japanese character for "ice".
Dr. Victor Fries/Mr. Freeze from Batman, now pictured above. Unlike other examples, though, his ice-based abilities are not actually powers per se, but ice-based weapons.
Bobby Drake, aka Iceman, from X-Men. That's just how he started out — turns out, he's an Omega-level mutant (that means his full potential is Phoenix-class!) with complete control over moisture. When Emma Frost (who is a psychic and normally has nothing to do with ice despite the name and the white outfit) took his body over, she did things with his powers that he could never do on his own... but he's learning bit by bit.
In the Draco story arc, Bobby Drake gets his head cut off (in Ice form). He later reforms it using the water coming from a demon opponent. Later, Beast issues a research paper regarding this unique mutation for Iceman.
He once cured himself of poisoning by replacing his entire body with new ice little by little this way.
Storm also has some Ice powers in the form of creating blizzards, but this is usually de-emphaized due to Superhero Speciation, and she uses more of her Thunderstorms and Tornadoes abilities. In the animated series, where Iceman wasn't around, Storm was more than happy to whip up blizzards that could flash-freeze things fairly quickly (though not as quickly as Iceman).
Tora Olafsdotter/Ice, Sigrid Nansen/Icemaiden, Dr. Joar Mahkent and his son, Cameron (both codenamed Icicle), and others in The DCU.
An issue of Justice League Adventures, set in the DCAU, featured a team-up of Icicle, Mr. Freeze, Captain Cold, Killer Frost, obscure Wonder Woman foe Minister Blizzard, even more obscure Outsiders foe the Cryonic Man, and downright "Sorry, who?" Batman foe the Snowman. All led by Polar Lord, a new villain from Polar Boy's home planet. The story was called "Cold War".
And the team of villains was called the "Ice Pack".
Elijah Snow from Planetary. Not quite frost projection, but the ability to draw heat out of an object on a molecular level; in his second appearance, he turns nerve gas to slush.
Captain Cold: His "cold gun" reaches temperatures of absolute zero, which causes water molecules in the air to immediately form ice, which can be used to freeze people (though because of his code against killing innocents, he usually simply holds people in suspended animation rather than outright kill them), create objects from ice, and also to produce a "cold field" which slows down things around him and is used as explanation as to why he might be able to deal with the Flash.
As of the New Fifty Two, he seems to no longer require the cold gun.
Killer Frost is an interesting variant as well: apparently created by someone with slightly more understanding of thermodynamics than most Ice People, she absorbs heat, rather than projecting cold. This means you can't Kill Her With Fire.
Made extra interesting by the fact that attempting to Kill Her With Fire just makes her happy — she uses the powers because she can't get warm, due to a side-effect of getting them.
Arctica Lagopus from the series The Extinctioners, an Arctic Fox with Ice powers. Didn't see that one coming.
Skurge the Executioner from The Mighty Thor. Using his Axe, he opens a portal (by cutting the air) to a dimension of cold, letting the icy wind blow onto his enemies. He can also do the same thing with a dimension of fire.
Ymir can create blizzards with no effort, among other such Ice-related abilities (he is much stronger than most Giants, as he is the original Norse one). However, unlike Frost Giants, he is an Ice Giant and seems to be literal living ice.
Kelda has weather control powers, which includes generating ice and forming weapons from it. And she can make poisonous ice.
Loki has many mystical powers at his disposal, but he's got a talent for ice magic thanks to his Frost Giant heritage.
Sub-Zero, from Blue Bolt Comics, gained ice powers when his spaceship passed through a comet.
Dr. Frost from Prize Comics had ice powers and would encase himself in ice to survive explosions.
Tor from Crack Comics had control over ice.
One-shot villain Icy Mike, for whom Empowered's boyfriend, Thugboy, once worked for.
Frostbite from DV 8 has an odd twist on the formula: his power is absorbing heat. He uses this to freeze enemies in their tracks, but he can also release his stored heat in an explosive blast.
John in With Strings Attached, thanks to his magical water-charm. Ice is just one of the many things he can do. Also, since he can alter the physical properties of water, he can create “warm ice” that won't hurt anyone it covers.
Fruits Basket fanfic The Eyes of the Cat allows a ghost to freeze the Big Bad alive by increasing the chill that being a ghost causes by about one million.
True to form, Amy gets these powers when she picks up the Ice Flower during the Mario World Saga in Mario and Sonic: Heroes Unite!. She gets these powers whenever she wants during the Sonic World Saga by simply using a Chaos Emerald.
Stars Above: The Ninth is a Demon made of ice that resides at the center of a frozen lake.
In Thor, the Frost Giants can create blasts of ice as well as shape it into weaponry. Loki is able to use the Casket of Ancient Winters to generate ice blasts as well, once he discovers his true heritage.
Ilke in Phenomena, she was given some of the spirit of a Frost spirit and can use most powers related to frost, like ice and snow.
In The Singer of All Songs, there are several kinds of chantments (magic songs). The Daughters of Taris, an all-female religious order, can sing the chantments of ice, and they protect their territory with a giant ice wall. Instead of combining with water (indeed, it's noted that the ability to swim isn't particularly common among them), the High Priestess also bears and passes on the knowledge of the chantments of ice that invoke darkness, the opposite of the chantments of fire which also have power over light.
The eponymous Wintersmith, of the Discworld novel, though this is just a subset of his general "Embodiment of the force of winter itself" bit.
In Thief of Time, we find out that Kaos, the fifth horseman who left before they became famous, has a sword that's so cold it goes beyond absolute zero and generates a sort of "burning cold" anti-heat. He uses it to keep milk fresh by putting it in the same room as a super-hot burning furnace.
The Clayr of the Old Kingdom trilogy, though primarily a clan of all female clairvoyants, use ice to amplify their Sight, hence why they live in a Glacier. When away from the glacier, they use spells to create a screen of ice on which they project their Sight, so as to show others.
Harry also figured out that he can adjust his fire spells to draw heat less evenly from the surroundings and, a couple of times, uses this to freeze water.
After he took Mab's offer of becoming the Winter Knight, Harry has been able to use ice-related spells much more. It was hinted that his new mastery of ice and his old mastery of fire are significant somehow.
The winter court in the Wicked Lovely series. Specifically, Beira the winter queen and Donia the winter girl. Donia later becomes the next winter queen after Beira's death. Her icy nature is caused by bitterness about being forced to become the winter girl, and thus not being able to be with her love, Keenan, the summer king - their very natures are incompatible, although it is implied that, after Beira's death, they at least try. I would imagine it would be painful; Keenan would end up covered in frostbite and Donia in burns.
The Haruki Murakami short story Ice Man...a woman falls in love with a guy who has "white patches of snow" in his hair and a look "piercing like an icicle" and it doesn't end too well.
In The Magicians, though we don't really see her use it, Janet mentions her discipline is a specialized form of cold magic.
Twilight Dragon has Princess Atoli, who is specifically known as the Sorceress of Snow.
Her dad, Ymir, who doesn't actually appear but rescues her and freezes Conan almost to death in the process.
The villain of Caroline Cooney's Freeze Tag combines this oddly with Taken for Granite—her basic schtick is that if she touches you, she renders you frozen and immobile, apparently forever, while fully conscious and aware. She never actually kills any of her victims and, at several points, undoes the effect just to toy with them. (This leads to part of the conflict over whether or not to kill her—if she can't be redeemed, a lot of people will stay frozen.)
Alexander Velitzyn, main character of J. M. Siderova's The Age of Ice, conceived on a bed of ice is immune to cold and when in a state of high emotion his flesh becomes painfully cold to the touch. In time he learns to control this, being able to make ordinary ice diamond hard and to turn water to ice at will. Extreme, as in Arctic level, cold puts him into a state of suspended animation. After doing this once he stops aging, his story extending over 250 years. It is hinted that he may be an incarnation of Old Man Frost.
In the Rainbow Magic series, Jack Frost, the goblins, and some of the fairies all have ice magic.
Power Rangers Operation Overdrive villain Flurious is the most prominent one in the series. He lives in arctic cave and can freeze you over and shatter you (though, this being a kids' show, you really don't see him do that a whole lot).
Lily from Misfits gains the power of freezing objects she touches. In the Nazi timeline, Captain Smith has Seth transfer her power into himself.
An early Monster of the Week in Smallville, in the episode "Cool", is a jock who gets the ability to freeze anything he touches. He's similar to Killer Frost; he doesn't project "cold" as if it's a thing unto itself as opposed to lack of heat. Instead, he absorbs heat, and has to do so so he won't freeze. Body heat works best for him, for no reason other than the fact that a guy sucking the energy out of fireplaces doesn't make much of a villain. A much later episode, Absolute Justice in season nine, introduces both Icicles (see Comics).
The fifth episode of MythQuest tells of the story of Minokichi and Yuki-Onna, a snow demon.
The Yuki-Onna from Japanese Mythology was often an extremely pale woman who lived within snow storms. Tended to guide travelers to either their frozen deaths or to safety, if she so wished to.
Jack Frost, natch. Generally, he simply brings winter to certain areas (winter/cold follows him everywhere), but some stories have him using his power to freeze people to death in an instant if they piss him off.
Poli'ahu of Hawaiian Mythology, along with her sisters/friends Lilinoe, Waiau, and Kahoupokane. She is their leader, and widely noted for her beauty. She is said to live atop Mauna Kea, though she visits other snowy peaks on the island. She is the antithesis to the fire goddess, Pele.
In Greek mythology, Khione was the daughter of Boreas, the North Wind, and was worshiped as a minor goddess who brought snow.
WCW wrestler Glacier had a whole entrance motif built around ice and snow. Fitting, since he was a knockoff...err, Captain Ersatz...of Sub-Zero.
Dungeons & Dragons has numerous variations and examples. Aside from the various deities of cold and winter, there's the Frostwind Virago that's the fey incarnation of the fickle and cruel nature of winter, the Frost Mage prestige class, the Winterhaunt of Iborighu prestige class, which eventually leads to transforming into an unholy abomination of ice and snow, the psionic Cryokineticist prestige class, and more.
D&D also has White Dragons, who have freezing breath instead of fire.
4th edition's different ruleset has killed "conjurer" and "evoker" wizard specialising, to be replaced by the classic elemental mages. Being an ice mage from level 1, with feats to match, is doable.
First edition had an evil humanoid race called "Frost Men'' who could shoot a "cone of cold" as an eye beam.
Jerza Wagner, a ghost from the Ravenloft setting, drains the living warmth from her victims and leaves them frozen solid. No, they don't wake up if you chip the ice away.
While the Darklord Meredoth is technically a necromancer, he uses lots of ice-based spells and has a frozen lair.
Champions, being a super-hero role-playing game, has clones of many popular superheroes and supervillains, including a Captain Ersatz of Iceman named Icestar. He lacks the former's frigid body-armor, but shares the wisecracking personality. (An old rules example for Presence Attacks has Icestar blasting a villain-carried crate and quipping, "Heads up, boys, the Good Humor man is here!")
Rifts has an optional Psychic Character Class called the Freezer, with various cryogenic powers.
Psychokinetic psions in White Wolf's Trinity could specialize in Cryokinesis, allowing them to freeze enemies.
The Winter Court from Changeling: The Lost get powers like this under the Contracts of Eternal Winter. They range from freezing any liquid solid instantly, to creating an aura of crippling cold, to causing a person to be hit by a hailstone the size of their head, to summoning a blizzard. Yes, even in hot climates.
Yu-Gi-Oh!: Even though Ghostrick Yuki-onna has the Dark Attribute, she has the effect of freezing her opponent if she gets destroyed.
Every single Toa of Ice in BIONICLE, plus a handful of other beings (though "a handful" does include an entire swarm of Kohrak).
Ōkami's last brush technique, Blizzard, is received from Itegami in Kamui.
X series: Chill Penguin from X1, Blizzard Buffalo from X3, Frost Walrus from X4, Tidal Makkoeen/Duff Mc Whalen from X5, Blizzard Wolfang from X6, and Avalanche Yeti from X8.
The Ice-type in Pokémon. One of the best offensive types in the game, super-effective against Grass, Ground, Flying, and most importantly Dragon, and Ice-type moves (especially Ice Beam and Blizzard) can be learned by nearly all Water-type Pokemon and a large number of other Pokemon. Nearly all Ice attacks have a chance of freezing the opponent solid, completely immobilizing it (and in Gen 1 they couldn't defrost without an item, a trip to the Pokemon Center, or being hit with a Fire-based attack), and some lower the opponent's speed. Defensively, however, Ice is one of the worst types, resisting only itself and being weak to Fire, Rock, Fighting, and Steel. Ice-type Pokemon themselves tend to have either high attack or special attack and mediocre to good speed, but low defenses and HP. The only Ice-type Pokemon in the two highest tiers of the metagame is Kyurem and its Formes.
Snow of Final Fantasy XIII learns the Blizzard series of spells, including Blizzaga (and Water), but no Fire or Thunder spells. He also gets to summon Shiva.
In Dissidia 012 Final Fantasy Tifa specializes in the Blizzard line of spells, to make her something of a counterpart to her canonmate Cloud.
Sub-Zero of Mortal Kombat. And his pupil, Frost, for that matter.
There were actually two Sub-Zeros. The first one was neutral/bordering on evil and was killed by Scorpion (and then switches over into using darkness when he becomes Noob Saibot). The second was his younger brother, who started off attempting to complete his brother's hit, but ended up becoming a genuinely heroic figure.
Celsius, the Summon Spirit of Ice introduced in Tales of Eternia. For that matter, Celsius and her costume in Tales of the World: Narikiri Dungeon 3 and Tales of Eternia's Keele, who apparently was assigned both Celsius and Undine for that game.
Also, in the Masou Kishin portion, the Water Herald Tytti Noorbuck (piloting Gaddeath) can use an ice area attack called Kelvin Blizzard. And in the Updated Re-release of Lord of the Elemental, the Hydro Pressure become Jotunheim, where she creat gigantic glacies to finish enemies. The rest of her attacks are water-based though. When she gets into the roster of 2nd Super Robot Wars Original Generation, Hydro Pressure also gains ice attributes.
Frost Wyrms and the new Death Knight class (which, like mages, can specialize in frost effects).
Racial conflict => external enemy required => a threat to all life => "too hot" (demons) and "too cold" (undead); logic at work, simple and elegant world design.
In terms of who's the frostiest class? In terms of raw number of (and amount of damage revolving around) frost spells, it is 1: frost mage 2: frost death knight 3: shaman 4: priest is getting a shadowfrost spell, so that's a half a spell for them.
The Lich King also has a number of ice-based techniques in his arsenal.
The third game adds Tsuruhime and Yoshiaki Mogami. The former an energetic young girl whose skill with the bow allows her to shoot ice arrows at her enemies and the latter can create ice sculptures as well as use feints and counterattacks.
Mia and Piers, of Golden Sun and Golden Sun: The Lost Age respectively.
Anyone, if they equip the right Djinn (or items for Frost in the first game).
Rief and Amiti in the third game.
Subverted in Fire Emblem. The Fimbulvetr and Blizzard spells have names and visual effects usually associated with ice magic...however, they're actually listed as wind tomes, since FE's anima magic doesn't include ice (only Wind, Fire and Thunder)
In general, the Bufu line of skills, which is a common element in the series alongside Agi and Zio spells. The most powerful skill of this element is Niflheim.
Mitsuru Kirijo in Persona 3 has an array of ice spells in her disposal, thanks to her persona.
In Persona 4 there are two ice users: Chie Satonaka and Teddie. Chie only barely counts, though. She stops learning ice spells around the time Teddie joins and ends up a beastial Kick Chick by the endgame. Averted by Yukiko. She actually uses fire skills.
Although the True Water Rune can be held by any of the three main characters, ChrisLightfellow has the best affinity for it.
Freezing is a powerup in Backyard Baseball and other Backyard Sports games.
Elena in Visions & Voices is the only playable character that can use Cold spells.
The Queen of Ice, the Big Bad of Enchanted Arms. Appearance and personality-wise, she appears to be an Expy of Edea and Ultimecia, although, instead of throwing ice or summoning a familiar that can, she's made out of ice and is the familiar.
Glacius from Killer Instinct is made of ice, he is also an alien, the inverse of Cinder, who is made of fire.
Sasquatch from Darkstalkers. Other characters, like Donovan Baine and Huitzil, also have some ice-based attacks.
Not elemental per say, but Commander Shepard of Mass Effect 2 is the only squad member with access to the cryo ammo power that allows their guns to freeze enemies solid and shatter them. Truthfully, only one out of the six classes Shepard can be lacks a freeze power.
Both Ice and Freeze Kirbys from the Kirby series can freeze enemies into ice blocks.
The Silver Age-styled video game Freedom Force has the former Soviet spy turned supervillain Nuclear Winter and his minions.
Inazuma Eleven sports two teams associated with ice: the first is Hakuren, a team of Hokkaido children, whose captain is Shiro Fubuki, who is able to perform both the effective Ice Ground (a ball-stealing technique that freezes the enemy while Fubuki skates through an ice field) and the outstandingly powerful Eternal Blizzard (a powerful shot that is performed by making the ball spin in midair, absorbing cold air, then striking it with all one's might). The second one is Diamond Dust, led by Gazelle and his mighty kick, Northern Impact (he disappears and then shoots the ball from an ice field).
Frostbite from Ghouls Vs Humans. He is an ice elemental born from the "doomed souls in the Arctic", who avenges the deaths of those who are murdered or betrayed in the icy desert. He looks like a giant, floating skull made of ice and has the power of an icy breath, as well as powerful icy armor.
Advance Wars, Black Hole Rising, and Dual Strike have Olaf, whose army is immune to the effects of snow on the battlefield and whose (Super) CO Power makes it snow for two days.
From RuneScape: To'Kash the Bloodchiller and Astea Frostweb (also a spider summoner) on the frozen set of Dungeoneering floors, both of whom can freeze the player in a block of ice; Icy Bones, who surrounds the players with ice spikes and freezes those who aren't next to him; Kamil, the boss guarding the ice diamond in Desert Treasure and its dessert-based expy/homage Karamel from the last part of Recipe for Disaster; and Lucien's ice titans, which can freeze the player in ice blocks, and ice demons, which create ice spikes around the player, trapping them in one place if they don't move.
In Kickle Cubicle, Kickle has the power to freeze enemies in ice blocks by breathing on them.
In the Metroid Blast attraction of Nintendo Land, there are some space pirates that shoot ice as opposed to actual damaging shots, and fire three times as many shots to make up for it.
Also, Ice Ridley, a Palette Swap of Ridley. Although that's less an ice person than an ice alien... dragon... thing.
From Antihero For Hire, Coldular/Froster/Cubenator, the ice-themed one-shot villain who picked a different name every damned time he spoke.
And managed to work up some cold-based puns that shamed anyone else on this list for their stupidity, and that is saying something.
With his recent reappearance, he's not said his new name but that doesn't stop the puns:
Coldular/Froster/Cubenator: I better make like a glacier and recede. Only, you know, faster.
Sil'lice in Drowtales, a Drow with an elementary affinity for ice (a snowflake is even part of her crest). She uses her powers to torture people by freezing their blood and certainly fits the "icy" part of this trope in personality.
In a world ruled by Mad Scientists like Girl Genius, it's no surprise that the firefighters are something like the Ninth Aetheric Vapor Squad. Their firefighting tools are Gas Condensers that, when kicked up a notch, can freeze a castle to the point where you can crack it open with a hammer.
The Global Guardians PBEM Universe has Centigrade (who combines this with Playing with Fire), Fafza Tel ("Winter Willow" in Hungarian), Icicle, El Halcon Blanco ("White Hawk" in Spanish), Flurry (who combines this with Blow You Away), Snowblind, Snowdrift, Chillblaine, Frost, Frostbite, Sub-Zero, Doctor Zero, Tundra, Iceberg, Lady December, and Snowstorm.
And inventor Mister Cool, who doesn't have the pwoer, but invented the equivalent of a freeze ray.
Frost from Trinton Chronicles is one of these - he creates and controls ice and cold into every useful tool he can. It also helps that he is immune to cold with the draw back that his powerful icy-aura can't be turned off, only down, makes dating and cuddling rather interesting.
As a sub-troupe, technically, the Fairy Sisters have a touch of this too, as they control the Ice Maze in the first story arc.
Danny himself, as well as a tribe of ghost yetis in Danny Phantom.
Professor Coldheart from the Dic era Care Bears cartoons. Not only was he a blue man with shock white hair, he also used a variety of ice-based science gadgets to freeze people's emotions and make them evil. Except during that one time he made a machine to cover the city in concrete...for some reason. Later aided by his sidekick Frostbite and his aunt, Auntie Freeze.
Man-arctica from Fanboy and Chum Chum, as well as Barry the Ice Monster, who controls the Frosty Freezy Freeze machine.
Also, a big fan of Man-artica, who gains ice powers from a super powerful Frosty Freezy Freeze that freezes him alive for the majority of the episode.
Jack Frost from The Brollys, the literal form of winter itself...and he's not a very nice guy for an ice guy.
In the first episode of Young Justice, several ice-based enemies (Mr. Freeze, Icicle Jr., Killer Frost, and Captain Cold) attack separate cities at once. The League finds this an unlikely coincidence and goes to investigate. It turns out that they were planning to meet up with Icicle Sr. in prison and planning a prison break. In a later episode, when North America is paralyzed by freak ice storms, Batman and The Flash go straight to question the previously established ice villains.
He actually uses the same pun as the trope title at one point. In the episode "Loyalty to the King", after shaving his huge beard, he introduces himself as "an ice king", is misheard as saying "a NICE king", and then he just runs with it until his true identity is revealed when the beard grows back.
My Little Pony: Friendship Is Magic gives us the Windigoes, winter spirits that feed off fighting and hatred. With enough hate, they could bury an entire land in snow and encase all of its inhabitants in ice.
Zane, the ninja of ice from Ninjago. He welds shuriken that freeze things they touch, and his special attack is a giant freeze ray.
No, really. A real life example in the form of Wim Hof. Skeptical? Many are, but the man really has survived stuff which should be impossible by human standards. He is even called "Iceman".
Ice-minus bacteria, such as Pseudomonas syringae, possess the ability to freeze water even at warm temperatures. Scientists believe their ice nucleating proteins are an integral part of ice crystal formation in clouds.
