Karuna is the self-proclaimed master of Ukuku Prairie. He bears resemblance to, and likely is, a Moblin. After Link has broken his sword in Angler's Tunnel, Karuna soon engages him in battle. He proves to be a strong adversary, besting Link and almost being the death of him. However, Nakura's help allows Link to both survive and gain a new sword. When Link and Karuna meet for a second time, Karuna is quickly struck down and killed.
Karuna's Japanese name is spelled as カルナ.
