This is one Micronauts custom that I was dreading doing since I planned it several weeks ago. Turned out a lot easier than I had originally thought. Had to do one of these to go with my Baron Karza figure.

I thought long and hard about what to use for the main body of the horse, and finally settled on the Centaur from the harry Potter figures on sale over here in England. The torso pops away from the horse quite easily, and only a small amount of filler was needed. I debated whether or not to add the side cannons, but I finally went with my initial idea and used the missile launchers from the SHS range with missiles from a model kit jammed in the end. I used another Cobra Commander figure as I wanted the torso to look exactly like the bipedal version I did.
