On one occasion, Skeletor used Night Stalker to infiltrate the Royal Palace. Unaware of its origins, Orko discovered the robotic horse in a meadow and took it to Eternis. Once Night Stalker was taken through the palace gate, a ray bomb dropped out ofthe robot and detonated, causing all the citizens of Eternis to fall asleep. At the same time, Zoar was imprisoned inside of the horse. In keeping with an old prophecy, Night Stalker's electronics ensured that the bird would turn into a demon if someone tried to set it free. Fortunately, Man-At-Arms managed to free Zoar without doing any harm, but Night Stalker remained in the Monster Warriors’ possession.
Later, Stridor carried Dragstor during his long and dangerous journey through the Plain of Eternity.

The robotic war horse called Night Stalker was built by Tri-Klops and Trap Jaw to counter the heroic Stridor. The robot gallops with remarkable speed despite its size and is equipped with two guns in front as well as one behind its iron saddle.
Skeletor rode Night Stalker into combat on several occasions, but it was the sinister Jitsu who took special interest in the armored steed.
