The Dragon Walker is another really wacky mechanical vehicle from the Masters of the Universe line like the Attack Track.There is a gear in the bottom of the dragon head that moves along a track in the base. When the head gets to the end of the track it rotates the entire base. This motion creates a very slow and bizarre motion.
The Dragon Walker is such a strange mix of technology and fantasy, it would only fit in the Master of the Universe line. I loved this toy as a kid and I had an awesome poster of Battle Armor He-Man riding the Dragon Walker in my room as a kid. The coat of arms on the side of the vehicle is kind of interesting.
I did pinch my hand in the gears as a kid trying to make the Dragon Walker "walk" without batteries. It was kind of traumatic as a little kid.
