Malladus

The Demon King is the antagonist of The Legend of Zelda: Spirit Tracks. Prior to the events of the game, the Demon King ruled over New Hyrule, and the inhabitants of the land lived in fear. Eventually, a rebellion broke out and the spirits of the land helped the inhabitants defeat the Demon King. Despite this, nobody had enough power to kill the being, and the people could only muster enough strength and energy to subdue him with chains and shackles and bury him underground. The shackles, extending the land of New Hyrule in four different directions, became the Spirit Tracks, and the surrounding community used these tracks as transportation railways. During the game, Chancellor Cole kills Princess Zelda and uses her body as a vessel in an attempt to revive the Demon King. To stop him, Link must ascend the Spirit Tower which has been broken apart into segments, and secure the Stone Maps.
