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. After Jitsu became lord of Snake Mountain, he retrieved remnants of the Hate Stones and implanted them in Night Stalker’s eye sockets. This action transformed Night Stalker from a mindless machine into a mechanical nightmare. From that day forward, Night Stalker’s eyes glowed with malevolence and ill-intent. Eventually, the demon steed turned on Jistu and ran off into the blighted plains of the Dark Hemisphere.
