Hyaku Shiki KAI. They didn't even label it the standard Full Armor tag and it definitely lives up to its special name.
This FA is gorgeous, one of the better ones I've seen for an FA, or Kai in this case. This was worth every penny I paid for and even though the calf section will always pop out, I still love it.
Look at that beast, re-fitted with heavy equipment throughout, it makes the Unicorn FA looks like a joke. Which it is but that's for another time.
To attain this magnificent look, I had to strip bare the Hyaku Shiki. It's almost as if it's an entirely a different form, like the Barzam and RX-178.
If you like Full Armor stuff, I'll recommend this figure. For its grandeur, I rate it 8.5/10. In fact, sometimes it's gems like this that makes exploring the Gundam world much more exciting.
