Tri-Klops is not only Skeletor's all-seeing minion, but also a sword-wielding warrior in his own right.
Originally a bounty hunter known as Trydor Scope, the warrior who would later be known as Tri-Klops was blinded in battle and forced to wear a special 3 part optic-enhancing helmet which expanded his tracking abilities. These abilities are activated by his helmet when Tri-Klops "turns" it:
1) Gammavision - the ability to see around objects.
2) Distavision - the ability to see in the dark similar to Night Vision.
3) Optic Energy Blasts
The Tri-Klops Action Figure also features the "power-punch" ability when the waist of the toy is twisted and released, rotating tri-optic headpiece, and a sword accessory.
Like the other Masters of the Universe figures, Tri-Klops came packaged with a Mini-Comic "Terror of Tri-Klops!" which featured the characters.
He also came packaged with a Glow-in-the-Dark "Warrior's Ring" for children.
