Behind the Scenes

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 Battle for the Crystal, Kayo sends a distress signal that is answered by the arrival of He-Man, Hydron and Flipshot.

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!"
