Valiant Space Warrior & Pilot from the Terra region of planet Primus located in the Tri-Solar System. His Energy Bazooka and devastating knock-out punch make him fearless in battle. So when an emergency arises, it is Kayo who pilots the Astrosub on a dangerous mission to find the enemy's base.
Battle Equipment: Space Helmet, Energy Bazooka, shoulder space armor.
His name is a play on "K.O", which is an abbreviation of the word "knockout". This is due to his punching abilities.
Kayo first appears in Skeletor's Journey trying to recover the Trifusium Crystal that was stolen by the Mutants Slush Head and Optikk. He is captured, but escapes during the distraction created by Skeletor's arrival, though fails to take the crystal with him.
In The Revenge of Skeletor! Kayo faces Optikk at the Titus observatory, and defeats him with a punch on his face/eye, accompanied by the one-liner "made you blink!"
