Galeem

Galeem (キーラ, Kiira) is the main antagonist of Spirits Ultimate. He is described as "Lord of Light" and the "ultimate enemy" in the World of Light. His goal is to recreate the universe in his own image.

History
Prior to the events of the movie, Galeem attacks the fighters, commanding an army of Master Hands. He uses his light attack to destroy and imprison all fighters except for Kirby, in addition to turning every non-playable character into a spirit; his attack engulfs the entire universe in a burst of light, leaving what is left of the world a barren wasteland inhabited by hostile spirits and puppet fighters cloned from the fighters imprisoned by Galeem. After Galeem's first defeat, Dharkon appears along with his army of Crazy Hands, driving Galeem away. Galeem later returns when Dharkon is defeated and flees into a dark portal, Galeem in pursuit. In the final world, Galeem wages war with Dharkon, while also seeking to destroy the fighters. But before Galeem can defeat Dharkon, both Galeem and Dharkon are finally defeated by the fighters, sinking into the ocean and exploding thereafter. 3 weeks later, Galeem attacks the fighters again, commanding an even bigger army of Master Hands. He uses his light attack to destroy and imprison all fighters, in addition to turning every non-playable character (except for the WarioWare characters except for Wario) into a spirit; his attack engulfs the entire universe in a burst of light again, leaving what is left of the world a barren wasteland inhabited by hostile spirits and puppet fighters cloned from the fighters imprisoned by Galeem.
