Note the wheeled centaur version shown on back. Probably the cooler of the centaur forms, IMHO. The best thing about both of the horses is that you could actually pose them in a reared-up position by balancing them on their back feet and the tail. The horse's legs were also amongst the most tightly jointed of any figure in the line. Also keep in mind that if you remove Oberon's hooves, you have four legs that can fit in any hole on any vehicle/figure! That should make for some interesting new combinations!
There were two versions of Oberon; the original Japanese version that has rounded missiles and a rounded tail tip; and the more common Hong Kong version that has the arrow-tipped tail and notched missiles.
