Characteristics
Guardians are ancient machines created by the Sheikah, originally created to aid in the battle against Calamity Ganon. Most Guardians are under the control of Calamity Ganon during the events of and are scattered across Hyrule, attacking those who approach. Guardians that are not possessed by Calamity Ganon's Malice, such as those that reside within Ancient Shrines, in the Trial of the Sword, at Upland Zorana, and in the Final Trial, glow orange and blue instead of the pink that corrupted Guardians display. Despite not being possessed by any evil force, they will still attack Link as they were tasked by the Monks to fight him as part of the trials that he must undergo.

While Guardians are formidable opponents, they have a few weaknesses. A Guardian's eye is their weak spot; shooting it with an Arrow causes extra damage and stuns them for a brief period of time. While sufficiently strong weapons can deal a fair bit of damage to Guardians, they are especially weak to Ancient equipment, which deals much more damage to them. The Master Sword, which doubles its attack power near guardians, is another effective weapon against them.

Guardian Stalker
Guardian Stalkers are powerful enemies, with high health, high resistance and a laser beam attack that deals up to 15 Hearts of damage. If a target is too close to them, they will attempt to distance themselves in order to fire their lasers; otherwise they will relentlessly pursue said target until they lose track of it. When defeated, they may drop any combination of Ancient Screws, Ancient Gears, Ancient Springs, Ancient Shafts, Ancient Cores and Giant Ancient Cores. Link can cut off the legs of a Guardian Stalker, temporarily stunning them.

Decayed Guardian
Decayed Guardians are decayed variations of the Guardian Stalkers that have long lost their mobility. They are found buried in the ground, unable to move due to having no legs. Decayed Guardians appear inactive until Link approaches it, when they light up and aim their laser sights at Link in preparation to fire.

Guardian Scout
Guardian Scouts are smaller variants of Stalkers that can be found within Ancient Shrines and Divine Beasts. They come in four different forms, ranging from I to IV. Depending on the form, these can be equipped with different weapons. The stronger variants found within the 'Test of Strength' shrines can also use their laser to repeatedly burn the ground surrounding them, sending Link back if struck. Additionally, when near death, they will charge a stronger laser attack that cannot be interrupted.

Guardian Turret
Guardian Turrets do not move, but instead fire powerful lasers at Link. They are only found around Hyrule Castle. Upon spotting Link, their head will begin to elevate and they will charge their laser in preparation to shoot. Several Guardian Turrets guard the entrance to the Sanctum of Hyrule Castle, where Calamity Ganon resides.

Guardian Skywatcher
Guardian Skywatchers are a flying type of Guardian. They scan their environment with a red searchlight and will begin charging their laser upon locating a target. Many Guardian Skywatchers patrol around Hyrule Castle and the Akkala Citadel Ruins.

Sentry
Sentries are a type of flying Guardian, similar to Guardian Skywatchers, that only appear on Death Mountain during the "Divine Beast Vah Rudania" Main Quest. Rudania dispatches Sentries as Link and Yunobo approach Death Mountain to hinder them as they attempt to disable Rudania. Sentries use red searchlights along the path up the Mountain which, should Link or Yunobo be spotted, will cause Rudania to furiously unleash Magma Bombs at them.

Trivia

 * Guardian Stalkers were based on the Octoroks from, which to people on the development team seemed huge in comparison to Link, leading to the cephalopod-like design of the Guardians and the technological theme of the game.
 * On the box art for can be seen a small, ovoid robot, reminiscent of aSeries:, with the legs and eye of a Series:.
