Tri-Klops is a character from both Mattel's toyline, Masters of the Universe and the Filmation and Mike Young Productions animated series' of the same name. He is a minion of the evil Skeletor and enemy of He-Man and the other heroes of Eternia. He wears a rotating visor helmet with three artificial eyes fixed to it, each with a special type of vision. In some media this gives him the advantage of seeing in three directions at once, while in others he sees only out of the front eye and rotates his visor depending on which type of vision he requires. The exact function of each eye varies in different versions of the franchise, although they usually are portrayed to be Distavision (the ability to see from far distances), Nightvision (the ability to see in the dark), and Gammavision (the ability to see through objects or around them); each eye also has a different optic blast.
