Yiga Footsoldier

The Yiga Footsoldiers are a type of Sheikah warriors that are part of the Yiga Clan. Like all other Yigas, they are Sheikah who turned their back on the Goddess Hylia and started to worship Ganon by using their ancestral magic and fighting techncs to destroy anyone who dare to oppose the Demon King.

Behavior
Yiga Footsoldiers can be found all over Hyrule, usually appearing disguised as travelers, transforming into Yiga Footsoldiers after Link speaks to them. After defeating Master Kohga, they might also appear out of thin air to ambush Link. Yiga Footsoldiers will often teleport around the area, shooting Link with a Duplex Bow and leaving themselves open to attack while aiming. If wielding either a Vicious Sickle or a Demon Carver, they will teleport above Link and down thrust into the ground with their weapon, telegraphing the attack with a glowing red ring of nine Hylian Letters. While infiltrating their hideout, Yiga Blademasters will summon Footsoldiers if Link is spotted out. They drop Rupees and Mighty Bananas when defeated.

Hyrule Compendium Entry
"The lowest-ranked members of the Yiga Clan. They've been dispatched all across Hyrule with a single task: seek out Link and end his life. They're a crafty bunch, sometimes disguising themselves as simple travelers or villagers to get the jump on you. Be wary of suspicious people you encounter. They're very agile and carry a bow and a one-handed."

Trivia

 * The glowing red ring of nine letters from the Hylian alphabet that appears behind them before some attacks parallels the nine glowing blue letters from the Sheikah alphabet preceding some of Monk Maz Koshia's attacks.
