Garo

The Garo are a race from The Legend of Zelda: Majora's Mask. Clothed in robes and armed with daggers, the Garo are an ancient race of Ikana Canyon, proficient in the art of Ninjutsu. According to a Pamela's Father, who studies paranormal activity in Ikana, they also apparently spied on Termina. They are led by the Garo Master; however, it appears that some time before the events of Majora's Mask, many or all of the Garo were killed and live on in Termina as empty shells known as Garo Robes, still continuing to spy upon Ikana. Various Garo Robes can be found throughout the canyon while wearing the Garo's Mask where Tatl senses a "thirst for blood."

Etymology
It is possible that the Garo are based on a real life tribe in India also known as the Garo.
