Guardians are enemies in The Legend of Zelda: Breath of the Wild. They are a group of mechanical enemies, all sharing a similar design and being products of the ancient Sheikah tribe's technology. They were originally programmed to defend Hyrule. However, upon the second rise of Calamity Ganon, the beast corrupted and took control of all the Guardians, turning them against Hyrule as extremely hostile beasts capable of ravaging an entire town alone. Guardians are resurrected during Blood Moons, despite being mechanical.
The Guardians were originally created by the Sheikah ten thousands years before the events of Breath of the Wild along with the four Divine Beasts, from their ancient technology, to protect the Hyrule Kingdom and aid the Princess of Hyrule and the Hero to defeat Calamity Ganon and sealed him. The Sheikah and their technology was firstly hailed as the power of the gods, but as time went on the people and Royal Family of Hyrule came to fear their power as a threat to the kingdom, resulting in the Sheikah becoming exiles.
One hundred years before the events of the game, King Rhoam Bosphoramus Hyrule became aware of the prophecy about the inevitable return of Calamity Ganon. This drove a search for the fabled ancient Sheikah relics. Upon their discovery, King Rhoam decided to excavate them. He then formed a group of skilled Champions commanded by Princess Zelda, and four elite warriors were selected from across the kingdom and tasked with the duty of piloting the Divine Beasts to assist Link, the appointed Knight and Hylian Champion. One hundred years prior to the events of Breath of the Wild, while the Champions were making preparations to battle Calamity Ganon, he reappeared and devastated the Kingdom of Hyrule by taking control of the Guardians and the Divine Beasts, killing four of the Champions in the process. A century after the Great Calamity, Link awakens from his slumber in the Shrine of Resurrection he first encounters remaining Decayed Guardians at the Eastern Abbey. He then finds more Guardian variants during his adventure.
List of Guardian types
There are several variations of these enemies:
The Guardian Stalkers found across Hyrule landscapes are large, mechanical spider-like creatures that remain inactive until Link approaches. They can fire energy beams from their eye. This energy beam will explode upon impact. If timed correctly, Link can use a shield block to reflect Guardians' energy beams. Although found mostly in Central Hyrule near Hyrule Castle, some defective ones can be found, in particular at the Temple of Time's ruins near the Great Plateau. Shooting an arrow to its eye can stun it for a short time.
Guardian Scouts can also be found in Shrines and Divine Beasts, they can wield and drop Guardian Swords, Guardian Spears, Ancient Battle Axes, and Guardian Shields of any weapon level (normal, +, and ++).
Guardian Skywatchers are flying Guardians found in certain parts of Hyrule, particularly south of Tabantha Tower and Akkala Highlands. They have the same HP, weapon, and body to the Guardian Stalkers.
Decayed Guardians are immobilized versions of Guardian Stalkers located around Hyrule Field and near Ja Baij Shrine (albeit disguised as defective). They are less durable compared to Stalkers, Turrets, and Skywatchers.
They are found exclusively in Hyrule Castle. Guardian Turrets behave identically to Decayed Guardians, only with more health and vertical range.
They are found exclusively in Death Mountain. Sentries, like the Guardian Skywatchers, hover in the skies and although they are incapable of attacking directly, they can alert any nearby enemies.
