Poe Sisters

Oracle of Seasons
In Oracle of Seasons, two unnamed Poe Sisters serve as the mini-bosses of the Explorer's Crypt (they are often unofficially named Amy and Margaret). One carries a lantern, leaving a trail of fire as it flies around, while the other carries a sword that it charges at Link with. Each of them are first seen in rooms that gradually darken, eventually casting Link back to the dungeon entrance if he is too slow to flee the room. They then appear in rooms next to the room they had cursed, where Link fights one of them. Finally, they fight together, forcing Link to not only attack them, but also relight the lamps they extinguish, lest he be expelled back to the dungeon entrance.

Ocarina of Time
The Poe Sisters were four ghostly siblings named Joelle, Beth, Amy, and Meg. They haunted the Forest Temple for many years until Link was able to put their souls to rest. When defeated, each yielded a different colored flame that illuminated a torch at the center of the temple. When all four torches were lit, Link was granted access to the temple's basement, where Phantom Ganon waited.

Majora's Mask
In Majora's Mask, they haunt the Spirit House of Ikana.

Twilight Princess
In Twilight Princess, there are four poes found in Arbiter's Ground, which might be related.

Phantom Hourglass
In Phantom Hourglass Link must rescue the four Cubus Sisters on board the Ghost Ship. It is then revealed to him that the Diabolical Cubus Sisters are in fact Poes. It is unknown if these are Meg, Beth, Joelle, and Amy. It is highly unlikely since they were red, green, yellow, and blue, meaning Meg would no be present.

Trivia
The Poe Sisters are named after the four sisters of the Little Women series by Louisa May Alcott.
