Darknut

Darknuts are heavily-armored sword-wielding knight enemies. They are very hard-hitting, adept at using shields, and often fairly intelligent relative to other enemies, and as such are usually some of Link's toughest foes.

The Legend of Zelda
Darknuts first appear in Level-3, Manji. They appear in orange and blue, with the blue ones being more powerful. Darknuts can only be damaged away from their shields, and they constantly move forwards with their swords, occasionally turning. They typically try to pursue Link, and very often appear in very large groups. They sometimes appear in water-filled rooms, where Link can use the stepladder to be out of their reach.

The Legend of Zelda: Link's Awakening
Darknuts, known as Soldiers in the Player's Guide, appear as the guards of Kanalet Castle who betrayed Richard. When a sword-wielding Darknut sees link, it will charge at him. Aside from wielding swords, they can be found without them, in which case they will throw spears. In fact, they are just a graphical and statistical replacement of Moblins, Pig Warriors, and Shrouded Stalfos, a fact which can be observed by swimming around the moat; during one screen transition, a Darknut will change into a Pig Warrior, and vice-versa. Inside the castle, one Darknut hides within a Darknut-shaped relief on the wall which can be bombed. This Darknut holds one of Richard's Golden Leaves. In DX, Darknuts, like Moblins, Pig Warriors, and Shrouded Stalfos, are blue. In the Nintendo Switch version, they are black.

The Legend of Zelda: Oracle of Seasons
Darknuts, again known as Soldiers, appear in various dungeons in both red and blue, wielding either swords or throwing spears. Due to their metallic armor, they can be pulled by the Magnetic Gloves. They can be found in the Unicorn's Cave, Ancient Ruins, Explorer's Crypt, Sword & Shield Maze, and in and outside Onox's Castle. A stronger golden one can be found along the Western Coast after a specific old man is spoken to.

The Legend of Zelda: Oracle of Ages
In The Legend of Zelda: Oracle of Ages, Soldiers are much more plentiful. Swordless Soldiers appear in the northern half of Talus Peaks outside Symmetry Village, where they are red in the present and blue in the past. Both colors appear in the Crown Dungeon, Ancient Tomb, and Black Tower.

The Legend of Zelda: Four Swords
Darknuts appear as strong enemies who will face anyone who slashes at them, and are also capable of slashing with their swords. When they slash, their backs are vulnerable. Once again, they can also be pushed and pulled around by the Magnetic Gloves due to their heavy armor. Like other strong enemies, their generation effect is a bolt of lightning instead of puffs of smoke. They have a "T" on their shields, likely short for their Japanese name, Tartnack.

The Legend of Zelda: The Wind Waker
In The Legend of Zelda: The Wind Waker, Darknuts appear in three different armor amounts, each of which has a different figurine. Additionally, they come in different colors, being grayish green with dark silver trim, white with red trim, gold with black trim, white with light silver trim, red with gold trim, and black with gold trim. The colors do not denote any functional difference, though ones of the same color are often found near each other. A green shieldless Darknut first appears as the mid-boss of the Tower of the Gods, guarding the Hero's Bow, and later appear as normal enemies. Later, shield-bearing ones, also known as Shielded Darknuts, appear only as normal enemies, first appearing in white armor alongside shieldless ones in the sunken Hyrule Castle, only becoming active once Link has gained the Master Sword. Some, also known as Caped Darknuts, wear burnable capes, and ones appear with fancier helmets and higher power called Mighty Darknuts. Darknuts are adaptable enemies, able to use a variety of sword techniques and alternate weapons if theirs in knocked away, or fight with their own hands.

Most of the time, Darknuts are found patrolling, though some stand perfectly still, imitating suits of armor and waiting for Link to approach. To defeat a Darknut, Link typically must first perform parries against its attacks to dodge around behind it and slice open the ropes holding its armor on, as well as dodging over it to knock its helmet off. Once its armor has been removed, it is revealed to resemble a jackal or a doberman pinscher, but with a nose shaped like Ganondorf's. From here, it can be attacked directly until it is defeated. They continue to punch and jump-kick at Link and will follow at a fast speed without their armor, and ones with shields never drop them. They drop the Knight's Crest as spoils. A photo of a cape-wearing Darknut always produces a Mighty Darknut figurine, even if it does not have the helmet.

The Legend of Zelda: Four Swords Adventures
Darknuts, known as Chief Soldiers in the Player's Guide, appear as large counterparts to soldiers, and are typically flanked by a battalion of them. They are capable of doing a forward-moving slash attack, and appear to wear bird-like masks. Once again, their shields effectively defend their fronts, while their backs are weak. They appear as minibosses throughout the game, with a blue one at Lake Hylia, a green one in Hyrule Castle, another blue one in Death Mountain Foothills, another green one in the Field, another blue one at the Swamp, and in blue, green, and red throughout later stages. The Knights of Hyrule are shown with the same bodies as Chief Soldiers.

The Player's Guide also once refers to soldiers or guards as "Darknuts."

The Legend of Zelda: The Minish Cap
Parsed Dark Nut, they appear in green with gray trim and white with red trim. They constantly face Link while hiding behind their shields, occasionally slashing at him. The green type is initially encountered in an underground room in Castor Wilds while Link is trying to find a special gold-colored Kinstone fragment. The white type is initially found as the mid-boss of the Fortress of Winds. The green type seems to have more health, while the white type is faster and tends to lunge forward as it thrusts more often. After these, neither color returns until the second floor of Dark Hyrule Castle, where a duo of green and white Dark Nuts is treated as equal to one of the more powerful type called the Red Dark Nut, itself first found in the Palace of Winds and capable of charging its sword into a corkscrew-like thrust. Dark Hyrule Castle also features an even more powerful type than that called the Black Knight.

The Legend of Zelda: Twilight Princess
In The Legend of Zelda: Twilight Princess, a black-armored Darknut that is roughly twice Link's height and wears a crested helmet appears as the mid-boss in the Temple of Time, and is capable of many techniques using its massive broadsword. Despite its strength, it is hampered by incredibly slow movement. While it defends much of the time with its shield, attacking it successfully and repeatedly chips pieces of its armor away. Once all of its outer armor is gone, it will throw its sword at Link and start attacking him with an arming sword (most likely an estoc). In this stage, it is much faster, and may even kick Link back. However, it is much less powerful and cannot defend nearly as well. Later, Darknuts with more typical horned helmets appear as enemies deep in the Cave of Ordeals and in Hyrule Castle, where they are usually fought in pairs, come in subtly different colors, being silver, red-tinted, and turquoise-tinted, and sometimes initially wield maces instead. The final Darknut, located in Hyrule Castle's tower, wears a unique set of gold-tinted armor. However, none of the armor or weapon variations denote any functional difference.

Link: The Faces of Evil and Zelda: The Wand of Gamelon
Darknuts appear, and are among the first enemies encountered with a large amount of hit points. Their shields can deflect projectiles such as bombs in some positions.

Hyrule Warriors
Darknuts with the Temple of Time armor from Twilight Princess appear as enemies. They are capable of throwing swords, as well as bumping an enemy with their shield while their eyeholes glow, before a wide slash, which leaves their critical hit bar open. Occasionally, their critical hit bar will seemingly open with no provocation, causing them to be among the simpler enemies to have one. Stalmasters act as stronger counterparts to them, making them the only special troops to have a reskinned version that is not a direct variant, or even from the same time period. Hylian Captains and Goron Captains additionally act similar.

Cadence of Hyrule: Crypt of the NecroDancer featuring The Legend of Zelda
In Cadence of Hyrule: Crypt of the NecroDancer featuring The Legend of Zelda, Darknuts appear as enemies. They resemble their appearance in The Legend of Zelda: The Minish Cap and wield extremely large swords. They notably appear alongside Iron Knuckles in this game, which are depicted as being rounder than the more muscular Darknuts. Normally, they cannot be attacked from the front, but they can perform a Spin Attack that hits surrounding spaces. If this happens, they will become exhausted for several beats, leaving them open to attack. It has a black variant known as a Black Darknut, which somewhat resemble the Black Knights from The Legend of Zelda: The Minish Cap except their palette incorporates red and blue instead of yellow.

Trivia

 * Phantoms from The Legend of Zelda: Phantom Hourglass closely resemble Darknuts, while they and the similar-acting Reaplings all have "Tartnack" in their internal filenames, being the Japanese name for Darknuts. This suggests Phantoms' models were originally intended for Darknuts before becoming a new enemy, or that Darknuts were simply used as a template and placeholder name for the new enemy. Functionally, Zora Warriors are more comparable to typical Darknuts.
