Char Aznable’s venerable MSN-0100 Hyaku Shiki rendered as a Master Grade HD version by Bandai. Based from my understanding of this version, this was a limited release only so I guess you shouldn’t expect to see a lot of shops carrying this. According to the product page at Hobby Link Japan, the HD stands for “High Definition” decals that was a special feature of this kit.
Soma Peries’ GN Archer from the Gundam 00 Second Season anime series. This is a support unit for the Gundam Arios and is able to dock with it. Without a GN Drive of its own, the GN Archer has to rely on the Gundam Arios to resupply its GN Condenser with power.
Seabook Arno’s F91 Gundam F91 from the Gundam F91 movie that came out in 1991. Included in this kit is a base stand modelled after the lafressia and perched inside that is a figure of “Iron Mask”. Haven’t really watched the anime of this yet, same with Gundam Wing. If I have time I’d like to delve deeper into the Gundam F91 universe because its storyline is situated in Tomino’s Universal Century Timeline.
