Gotten this supreme class transformers awhile back from my local Toys'r'us, though Takara released a animation accurate version and the 25th aniversary version, I still prefer the armada head sculpt. The only problems or issues with this version, is the translucent parts which really turns me off. So I decided to repaint mine with some paints I got from model kit shop.
Repainted the chest, groin and head, finished with a gundam marker for the panel lines, now thats much more like G1 Unicron I know.
