Hyu

Hyus are a strong type of Poe. Unlike normal Poes that have open hoods, Hyus have solid sheets with eye and mouth holes.

The Legend of Zelda: A Link to Past
In The Legend of Zelda: A Link to Past, Hyus appear in the Dark World, where they swoop back and forth like Poes, though somewhat faster and further. They appear in the Ghostly Garden, Village of Outcasts, and Skeleton Forest.

The Legend of Zelda: A Link Between Worlds
In The Legend of Zelda: A Link Between Worlds, Hyus appear in Lorule, acting basically the same as before, albeit slower. They appear in the Graveyard, Thieves' Town, Skull Woods, and the Treacherous Tower.
