Cyclos
Cyclos is a frog like wind god found in The Wind Waker, and is Zephos's brother. Cyclos used to be as kind and wise as his older brother, but once he got angry from his broken shrine, he dedicated his life to control the cyclones of the sea and wreak havoc on all who encountered him. Many say that if one could harness the power of Cyclos' magic, there would be no telling how useful cyclones could be.
Link can find Cyclos in a humongous cyclone throughout various parts of the Great Sea. If he sails close to it Cyclos will draw him him, giving Link a slim chance to defeat him with his bow before being blown away into another part of the Great Sea. If Link succeeds in defeating Cyclos, he will calm down and teach him the Ballad of the Gales before returning home.
