Yiga Footsoldiers are enemies from The Legend of Zelda: Breath of the Wild. They are Sheikah renegade soldiers of the Yiga Clan and followers of Calamity Ganon. Link confronts them at the Yiga Clan Hideout in their usual appearance or in Hyrule disguised as travelers. Once Master Kohga is defeated, they will start attacking Link more frequently across Hyrule.
Across Hyrule, they are disguised as ordinary travelers, waiting for Link to talk to them. Disguised Yiga Footsoldiers are always named "Traveler." When Link interacts with them, they tell a set of odd dialogue and then threaten Link's life, examples being "This is the end for you Hylian Champion!" or attempting to sell Link overpriced Mighty Bananas.
After speaking to Link, they remove their disguise and disappear after drawing the Yiga symbol with fire. Then they reappear, striking with a Vicious Sickle, or a Demon Carver if Master Kohga has been beaten. They will sometimes appear from above, striking down, or will rush Link at high speeds. When defeated, they will drop Mighty Bananas, a random number of Rupees and often their wielded weapon.
