Cyclopses are a race of one-eyed creatures that appeared in The Lion, the Witch, and the Wardrobe. Their heights range to at least ten feet tall.

It's quite unknown where they lived in Narnia, but they were followers of the White Witch, and were very strong. They served as personal throne-bearers for her, carrying her wherever she desired.

After the Long Winter ended, all the Cyclopeses in the land of Narnia traveled to the Stone Table, to gather as soldiers in the White Witch's Army. They were first seen in the White Witch's camp, where they were preparing for Battle, with the Ogres, Hags, Boggles, Dwarves, Minotaurs, Minoboars, Ghouls, and Ankle Slicers.

Apparently, the Cyclopses were not all bad, as there is a shot of one, which you can catch a glimpse of, working in Caspian X's forge in Prince Caspian.
