Shadow Beasts are the muscle behind Zant's twilight invasion. The Shadow Beasts are dark, willowy beings that drop out of Portals and always travel in packs of three or more. Should one fall during a group battle, the others will utter an unearthly howl that rejuvenates it. Shadow Beasts are transformed twili and humans.
Their Japanese name Kage no Shisha and ability to revive fallen Shadow Beasts may be a reference to the phrase "Shishawoikasu", meaning "to raise the dead".
