Ache

The Ache (エーク, Eiku) are blue and purple bats that are related to the Keese, although more resilient in combat, harder to destroy, and that have magical abilities. They can disguise themselves in the villages of Hyrule as an ordinary Hylian. They can be killed with bladed weapons such as a sword. They made their debut appearance in Adventure of Link. Most often found in caves and trees.

The Acheman is a close relative to the Ache.
