Agahnim

Agahnim was a wizard who stopped sudden disasters in Hyrule, and was made royal advisor. However he was actually a pawn of Ganon and he betrayed the King by killing him and possessing all of the royal guards. He used his power to take over the throne and kidnap the Seven Sages' descendants, using their power to break the seal of the Seven Sages. Link defeats Agahnim by reflecting the wizard's magic back at him with the Master Sword or the Bug-Catching Net.
