Dark Sun

The Dark Sun is a boss monster in Miitopia, and the final monster in the Nintendo 3DS version of Miitopia. It is a two-sided circle within a silver spiked ring with several circles with Mii eyes orbiting it. The central circle is blue on one side and silver on the other and holds a Mii eye and Mii mouth. Defeating it in the Tower of Dread results in finishing the tower.
