Tri-Klops is an inventor, but is overshadowed by the skills of Man-At-Arms. Not only is he an inventor, but he is also an excellent swordsman.
Tri-Klops wears a three eyed helmet. One of the eyes can conduct telescopic vision and night vision, the second energy blasts and light flashes, the third can foresee the future.
One of the adaptions introduces Tri-Klops as a blind guard to a wizard. Skeletor returns sight to the guard in exchange for killing his master. Tri-Klops then joins Skeletor's Masters of Evil.
