"A bat that lives in dark places. Usually, it hangs upside down from trees or in caves."
— Zelda II: The Adventure of Link manual
Aches are blue bat-like creatures, similar to Keese, and attack by swooping down to claw at their foes whenever they approach. Aches are masters of disguise and are known as the "eyes of Ganon". They occasionally disguise themselves as normal villagers roaming various towns to attack heroes who might hinder the resurrection of Ganon. Some Aches can also transform into demonic shapes known as Achemen.
