Night Stalker is the evil counter part to Stridor the heroic robotic horse. These two robots are exactly the same besides their paint schemes. He's armed with two forward facing cannons and a rear cannon. Night Stalker's gold, black, and purple color scheme is far more striking than Stridor's paint.
My Night Stalker has his tail, but his missing his helmet. Night Stalker has some really great detailing on his legs, but unfortunately they are totally static.
Some "gift sets" included Jitsu, similarly to the Fisto and Stridor gift sets. I really liked both robo-horses as a kid.
