Garo

The Garo is a race that appeared in Majora's Mask.they are the lingering spirits of an army that once invaded the Ikana Kingdom.

They are summoned by the Garo Mask "Master you called!" in Ikana Canyon, and when not wearing it, Tatl will sense "blood thirst looming around" and she advices you to wear a mask which allows you to see beyond

As the fight starts, a ring of fire will be cast, preventing escape, they use very sharp swords which can be easily blocked with the shield and render them weaponless and shocked, they aren't much of a threat, and are in there to give out information.

After killing them they will "surrender their wisdom" and explode themselves shortly afterwards saying: "To die without leaving a corpse, that's the way of us Garo"
