Line created by Bandai in 2006 that aims to improve in the form of busts some Saint Seiya's characters, updating their appearance to the design level of the most recent figures. Varieties of faces with new expressions and hair with new shapes that greatly improve the expressiveness of the figures are added. In 2007, two new different versions of Appendix go on sale, the Plain Clothes of Seiya Pegasus and Shiriu Dragon, with a full-length figure, the Pandora's box and a scale version of the object V2.
In 2009 OCE versions appear, with new accessories not included in the original versions, and also the Pandoras'box in metal of the Gold Saints, divided into four volumes. In 2010 the Appendix Gold Saints Object, the twelve totem of the Gold Saints, and the Appendix Display Stands DX appear. The line officially closes in 2012, but in 2017 two more deliveries go on sale to celebrate anniversaries or a promotional World Tour.
