This paper toy is a chibi Kadaj, the primary antagonist of the novel Final Fantasy VII Lateral Biography Turks -The Kids Are Alright- and the secondary antagonist of Final Fantasy VII: Advent Children, the papercraft was created by smilerobinson.
An embodiment of Sephiroth's will manifested from the Lifestream, his goal is to find Jenova, whom he considers his mother, and bring about a second Jenova Reunion. The novel Final Fantasy VII Lateral Biography Turks -The Kids Are Alright-, written by scenario writer Kazushige Nojima, sheds some light in the events that happened prior to Final Fantasy VII: Advent Children.
Like the other embodiments of Sephiroth's will, Kadaj resembles Sephiroth to a great degree and is described by Vincent Valentine as a "larval" form of Sephiroth. Kadaj wears black leather clothing with gauntlets and a coat, which he keeps zipped up. The image of a single wing is sewn on the back of his coat as an allusion to Sephiroth. He has shoulder-length silver hair that partially covers his face and green cat-like eyes. Kadaj's weapon is the Souba, a katana with two parallel blades that he carries in a sheath on his lower back.
Kadaj embodies Sephiroth's cruelty and insanity. He is devoted to Jenova and dedicated to finding her, but is unaware of Sephiroth's influence over Jenova. As a result, Kadaj is insecure over Jenova "choosing" Sephiroth over him, and though he does not fully understand who Sephiroth is, he tells Rufus Shinra he can sense his presence.
Kadaj is arrogant and mocks Rufus and the Turks, and thinks of Cloud Strife as his "brother" through Jenova, but considers him a traitor to their cause. When driven to anger Kadaj attacks with fury, such as when he attacks Cloud when Cloud reminds Kadaj he is only Sephiroth's pawn. Nomura describes him as "talking quickly, then speaking slowly or breaking into laughter for no apparent reason". [Source: wikia]
