Chancellor Cole is one of the main antagonists of The Legend of Zelda: Spirit Tracks. He was the royal advisor to Zelda until she decided to investigate why the Spirit Tracks were disapearing. She had gotten on a train with Link which soon became derailed due to the disapearing tracks. He is the one who actually killed Zelda using a shot of darkness. He wore two green hats to cover up his twin horns.
His plan was to resurrect the demon king, Malladus, and eventually succeeded, although his plan to have Malladus possess Zelda's body was foiled, so Malladus possessed Cole instead. When Zelda was revived, and she and Link destroyed Malladus, Cole was destroyed along with him.
