Characters that fight with multiple blades attached to their hands or fingers to emulate gigantic metal claws. The blades can be a natural part of their body, artificial implants, stuck on a glove or gauntlet, or actually be a variation of bladed brass knuckles. Wolverine Claws on a good guy is used to demonstrate Exotic Weapon Supremacy; on a bad guy they show that he or she is especially bloodthirsty and likely Ax-Crazy. Any character sporting these will be improbably effective with them. When these weapons are unsheathed, they often make a distinct "snikt!" noise or some variant.
Weapons of these type are presumably easier to conceal and use in close quarters, depending on the size and nature of the blades. However, in fights involving larger weapons they would be less effective considering their limited reach compared to a sword or polearm.
Weapons of these type were actually used in early civilizations. The Bagh Nakh, or Tiger's Claw◊, was developed in India for self-defense and used by the first Maratha Emperor Shivaji. Ninjas also used Nekode◊ (Cat's Paw) for fighting and Tekagi-Shuko for utilitarian purposes, such as climbing trees.
Artificial Limbs and Swiss Army Appendages may be modified to feature Wolverine Claws. Subtrope of Blade Below the Shoulder.
In the 2012 Chinese animated series Kodama, the main character's side-kick finishes off the monster of the day by using the claws from his hands on its core.
Wolverine is the Trope Namer. A lot of people forget that an early plan for Wolverine was that his gloves contained the claws. The writers eventually decided that then, anyone could be Wolverine by putting on the gloves, and made it so that they were inside his body.
X-23, Wolverine's female clone. Has 2 metal claws per hand, and 1 per foot.
Wolverine's son, Daken, has three claws per hand: two from the knuckles, and one from the wrist. Or, at least, he used to. Wolverine tore out his wrist claws and by virtue of them having been coated with metal from the Muramasa Blade, he can no longer regenerate them.
Wolverine's long time foe, Lady Deathstrike, is a cyborg with fine blades coming out of her finger tips.
During the events of The Other, Spider-Man developed poisonous hand stingers that he even calls a case of Logan Envy. When Peter protested that spiders don't have stingers, The Other responded that they will... in the future. Even before the Cosmic Retcon of One More Day, they weren't used much (some writers claiming that they only came out around "fellow totemic beings" as a defence mechanism). It's been revealed that Kaine (the new Scarlet Spider) has them as well.
Romulus has four fingers (maybe) and clawed gloves - because he's based on the earliest concept for Wolverine.
The Ultimate version of Sabretooth has four per hand. Wolverine said something to the effect:
"Yeah, that will make people stop calling you the poor man's Wolverine."
Basic Continuity Sabretooth has been known to sport oversized adamantium claws on the tips of his fingers on occasion.
Squirrel Girl has a short knuckle spike. According to Iron Man, it's not exactly at Wolverine's level, but it's something.
Interestingly, both the X-Men Noir and Wolverine Noir versions of the character keep the claws but manage to change them into something appropriate for the 1930s time period — a pair of Japanese neko de in the former and a set of special knives in the latter.
In the Golden Age issue of the WildCATs/X-Men crossover comics, Zealot gives Wolverine a wrist weapon that simulates his claws, noting "I...suspected you would like it."
In Battle Of The Atom, Future Jubilee and Raze Mystique and Wolverine's future son have these.
In Secret Six, Catman uses a three-clawed Bagh Nakh, and Scandal has retractable forearm-mounted blades called the Lamentation Blades.
Carnage from Spider-Man does this on occasion when preparing to kill someone because his suit can generate weapons.
Both Shirlee Bryant and Greer Grant Nelson had clawed gloves and taloned boots as part of their Cat costumes. The claws were retractable, and could also be detached and cast on cables as grappling hooks. (See Marvel's "The Cat" series (1972-1973).) The Hellcat (Patsy Walker) possesses similar weapons.
In Grendel, one of Tujiro's goons fights Christine Spar as Grendel with a glove with wolverine-style claws attached. Christine notes that it's a stupid weapon with no reach, and easily cuts off the goon's hand.
Grren Lantern foe the Predator includes twin blades that snap forward over his knuckles in his arsenal.
In Undocumented Features, "Wolverines" are the slang name for cyberclaws of this variety even before Logan is imported from a parallel Marvel Universe.
Boltie in Super puts on Wolverine-styled claws in the film's climax.
In Transformers, Tyrese Gibson sees various claw marks on a wall and notes "Was Freddy Krueger up in here?" Anthony Anderson corrects him, saying that Freddy Krueger had four blades and there are three on the wall, indicating the presence of Wolverine.
Wolverine. Obviously. Both bone and adamantium versions.
In The Wolverine, his weapons of choice are still the metal claws that pop out of his hands.
Victor Creed/Sabretooth has them on his fingernails, instead of knuckles.
Molly Millions from William Gibson's Neuromancer (and several related works) has surgical-steel blades that pop out from under her fingernails, probably inspiring the ones in Shadowrun.
In PC Hodgell's Chronicles of the Kencyrath, Jame and some other Shanir ("natural Arrin-thari") have claws instead of nails on the hands and sometimes feet. Examples are Jame (who has retractable claws on her hands), and Bear (who has fixed talons on both hands and feet). Steel-clawed gauntlets allow non-clawed Kencyr warriors to fight in the Arrin-thar style as well. Kallystine also uses a razor-ring, which only has a single blade.
In the Paradox Universe claw-knives, which are gloves with retractable blades meant to mimic the claws of feline Pelted, are illegal in the Alliance, but Lisinthir is given a pair when he becomes ambassador to the Chatcaava as they have very long claws which they use in duels.
Alysha Forrest lost her natural claws and replaced them with prosthetics made of a molecular alloy called breathnache, which also made them Absurdly Sharp Claws.
This trope appears multiple times in the Kamen Rider franchise
Kamen Rider Ryuki example. Kamen Rider Tiger uses clawed gauntlets as his main weapons, which he gets from his Contract Monster, Destwilder. The same goes for his Kamen Rider Dragon Knight counterpart, Kamen Rider Axe.
The leader of the demon bikers in the Season 6 opener.
The Master has them. "You have something in your eye."
In Arrow, Bronze Tiger uses three knuckle-attached blades.
Spurs from Shadowrun were a cybernetic enhancement that gave a character a blade that sprouted from right above the wrist. Fingernail razors were a somewhat more subtle weapon that came from the fingertips. The Shadowtech supplement added a strap on version of the wrist blades.
Lightning Claws in Warhammer 40,000, apparently a standard issue for Imperial Guard generals. Not to be confused with Power C/Klaws, which are essentially pointyPower Fists.
In Abney Park's RPG, Airship Pirates, Neobedouin beast dancers use a weapon called Beast Claws: a set of blades attached to the hand, emulating... well, the claws of a beast.
Also: Claw Bracers, from the Forgotten Realms. Favoured weapon of Sharess, Goddess of Cats and Whores, also preferred by Cult of the Dragon spellcasters. Basically, daggers that can't be disarmed and leave the hands free - say, for casting fireball.
Savage Species brings us the Beast Claws, magical gauntlets with clawed fingers built for use by characters with existing natural weapons.
Arcana Unearthed and Arcana Evolved had the Battle Claws, exotic weapon gauntlets with claws on each finger. They were especially favored by the leonine Litorians.
Dark Sun gave us wrist razors. Very deadly in the hands of thri-kreen.
Exalted has mundane and artifact versions of tiger claws. They provide bonuses to climbing as well as maiming.
R. Talsorian Games' Cyberpunk has "Wolvers" that act like this.
Alternity gave us the cyberklaw, like Shadowrun's spurs but ... bigger.
Eclipse Phase has both cyberware and bioware claws, the cyberware type is made of smart materials, come out of the back of the hand, and extend six inches past the knuckles. Bioware claws are more cat-like, and legal in most habitats because they're so small.
Several fist weapons in World of Warcraft are gauntlets that have these attached to them. In one of the game's many, many shouts-out, one set can be seen sported by a wolverine-person named Loguhn.
City of Heroes has the Claws power set for this, as does Champions Online. While the latter's claws are obviously similar to bladed brass knuckles, the former's look more like they come out of the character's hands. City of Heroes claws appear to come out of your hand because all weapon-based powersets, when not actively in use, are stored in Hammerspace. The actual style of the claws varies from Wolverine-style claws to spikes on the back of the hand, a long flat blade from the back of the wrist a la Assassin's Creed, and even an option for wristblades made of energy.
Arachnos Blood Widows (both an NPC enemy and playable class) use both short claws and the retractable shortsword. The "claws" are really poisoned darts, which can be launched singly or in bursts. PC Widows start out with them as part of the mandatory uniform, but can evidently get surgical versions once undercover work starts turning up.
In Dawn of War, the Imperial Guard hero unit is armed with retractable claws as his melee weapon.
In the entries of the Final Fantasy series where monks can equip weapons, these are traditionally what they are.
Yang in Final Fantasy IV uses these as the sole weapon he can equip. In his case, claws provide only a minimal increase to his attack power, and in fact the first ones acquired don't improve it at all; they just add elemental effects to his attack.
Ciel emulates this trope by holding multiple swords between her fingers.
As does fellow burial Church agent Kotomine in one path of Fate/stay night.
Date Masamune/Azure Dragon from Sengoku Basara does this when he's drawn all six of his swords, holding three in each hand between his fingers. It gives him a more powerful and effective moveset, though at the cost of being able to defend.
The Battle For Wesnoth's new Drake sprites sport Wolverine Claws - the logic being that, as clawed predators in the first place, they'll instinctively use them more effectively than more traditional weapons.
Zhang He, from the Dynasty Warriors series, at least in games 3-5. In 6 he ditches the claws in favor of a remarkably generic spear, but gets them back in the PS2 version and in the "Empires" installment. Nouhime in Samurai Warriors can use these.
Taokaka sports a nifty pair of retractable, metallic claws. It's not clear if those are biologically hers or actually hidden weapons.
The (technically non-canon, but accurate in their exposition) unlockable "Teach Me Ms. Boobies Litchi" Omakes indicate that the ability to draw her claws is a natural ability (since she doesn't have a weapon which can draw the series' phlebotinum from the environment).
Voldo and his katars in the Soul Series. His arsenal over the course of the series includes "cat claws" that play it very close to Wolverine, handheld drills, and swinging pendulum blades, minus the pendulums.
As of V, newcomer Viola uses the razor-clawed glove version on her right hand as well.
The Ogre Battle series features Ninjas, Ninja Masters, and Brawlers using these in some games.
Zuul from Sword of the Stars have "punchclaws" protruding from their forearms and extending over the back of the hand. They are vestigial in the males, but the females' are very effective at cutting through things. The Pit allows you to craft "Adamantium Claws", complete with Shout-Out in the description to the Trope Namer, as well as the more Freddy Krueger-like "Razor Fists".
Bayonetta has the "durga," which can be used on the hands or feet but otherwise plays the trope straight.
The second boss in Streets of Rage uses these. He's pretty fast with them too, making him a tricky fight. Two of them appear later on!
WWE's Smackdown vs Raw 2006 had some Wolverine Claws you could give to your created wrestlers...and ironically, in 2011, the game where they had several super-hero items to recreate your favorite heroes (including Wolverine's hairstyle), they left the claws out. Missed opportunity of awesome? Oh, definitely.
In Kid Icarus: Uprising, Pit has a class of weapons that looks like this. Most have powerful melee combos, but some, like the Beam and Artillery Claws, are better suited to shooting stuff.
Fallout 3 features the craftable Deathclaw Gauntlet, the severed hand of a Deathclaw in all its deathy, clawed glory, rigged up with various belts and leg braces into a weapon. It returns in the Lonesome Road DLC of Fallout: New Vegas as the Fist of Rawr (or with Wild Wasteland, Fist of the North Rawr) though it has to be crafted from a boss-level Deathclaw, who unsurprisingly is named Rawr.
In Skyrim, the Stormcloak Commander uniform has spikes attached to the gauntlets, like their mascot. It's subverted in this does no additional unarmed damage, but with the right enchantment, it could be one of the most damaging unarmed weapons in the game.
In Marathon: RED, the player's mutant form has these as melee weapons.
The Berserker class starts with a set of these in Torchlight II, though they're explicitly (and exaggeratedly) a set of spiked/clawed knuckles and most special abilities look exactly the same regardless of weapon choices later on.
Dead Island allows you to modify certain classes of brass knuckles to form these. The text for the mod specifically mentions that they were inspired by "a certain superhero". Funnily enough, John Morgan is modeled after said superhero enough that the proposed movie could easily have Hugh Jackman in the role.
In Borderlands 2, Gaige has the "With Claws" skill that quickly forms a set of glowing energy claws on her robotic left arm and makes her to do a quick double-slash against an enemy, dealing increased melee damage as well as Life Draining them.
Gaia Online's Old Man Logan has fishhooks on his knuckles for claws; he runs the fishing minigame. zOMG! lets you craft a set for your avatar.
Parodied in the "Super-Griffins" segment of the Family Guy season 3 episode "Family Guy Viewer Mail #1", in which the Griffins start abusing the superpowers they acquired after being bathed in nuclear waste. Of all the cool powers (Peter being able to transform into anything he wants at will, Brian's super-speed, Chris' pyrokinesis, Stewie's telepathic abilities, and Lois' super strength), it is, of course, the show's Butt Monkey, Meg, who can only grow her fingernails barely an inch in length in a similar fashion, with the only collateral she can do amounting to lightly scratching the skin of some person who dissed her worth.
Megabyte of ReBoot. Oddly enough, Megabyte was shown to have both extensible claws in his fingertips and three blades from the back of the hand. Whether this is just an inconsistency is unknown, but when Megabyte was upgraded into a Trojan Horse Virus his claws were particularly gnarly.
The Shredder from Teenage Mutant Ninja Turtles has gauntlets with two clawlike blades on the back of the hand that he uses as weapons. His suit is full of blades and quite dangerous-looking, leading to comparisons to a can opener by Michaelangelo when they face him in The Movie. Oddly enough, it's only that one pair of claws that are ever used as a weapon. The rest of his suit is apparently decorative. As of the 2012 series, he also has a pair of retractable sword blades in his gauntlets.
Some examples of "tekagi-shuko" claws used by feudal ninja do resemble this, being worn on the back of the hand with extended claws. They were principally a climbing tool but could also be and likely were used as a weapon in a pinch. The better known nekode design, with short spikes worn on the inside of the palm, appears to have been more common.
There are several species of newt that can puncture their sides with their own ribs when seriously threatened. Often, this punctures poison glands as well, injecting venom into the mouth and/or bloodstream of whatever predator is trying to devour them.
