The Gundam FIX Figuration (aka G.F.F.) series of collectible figures was started based on the Gundam mechanical designs of Hajime Katoki and his 'Gundam FIX' illustration artbook and are released by Tamashii Nations, a Bandai 's characters based toys line. These figures share similar features as those found in the MSiA series, but are considerably more detailed and often include more accessories.
