Hyrulean Captains (also known as Hylian Captains) are captains of the Hyrulean Forces units in Hyrule Warriors and Hyrule Warriors Legends. While they are normally allied units, they also appear as enemies in certain scenarios.
More experienced than the Hyrulean Soldiers they lead, Captains are fight wielding Swords & Holy Hylian Shields. Though their abilities pale in comparison to those possessed by the Hero, Sheikah, and even Princess Zelda, they are still an important part of the Hyrulean Forces. However they are shown to be susceptible to brainwashing, which can cause them to turn on their allies.
These Hyrulean Captains wear uniforms and armor identical to that worn by the soldiers they lead. The only difference is their rank and that they fight wielding Holy Hylian Shields.
These Hyrulean Captains wear full body armor including Hylian Captain Gauntlets.
In The Sorceress of the Valley, a Hylian Captain called Engineer appears. He identifies himself as a member of the Hyrulean Engineer Corps, the combat engineers within the Hyrulean Forces. Engineers are basically a type of allied unit that the player protects to accomplish a task. In The Sorceress of the Valley, the Engineer appears to lower a bridge to allow the Hyrulean Forces to advance.
