This papercraft is a chibi Thanatos, the ultimate Persona of the Death Arcana in the role-playing video game Shin Megami Tensei: Persona 3, the papercraft was created by Kiri. The size of finished model is about 220 (H) x 228 (W) x 206 (D) mm.
Thanatos first appears near the beginning of the game, when the protagonist first attempts to summon Orpheus. Thanatos emerges from Orpheus' head, ripping Orpheus apart and mercilessly slicing apart the Arcana Magician looming ahead. Later, the protagonist can gain accessibility to Thanatos after the Social Link with Pharos is completed.
Thanatos' fusion prerequisite requires all the Personas of the Death Arcana, namely Loa, Pale Rider, Samael, Mot and Alice to perform a pentagon-spread fusion in the Velvet Room. Thanatos also grants the equipment Ring of Darkness, which repels Darkness-based attacks, as his Heart Item.
Ryoji Mochizuki's true form as Death looks identical to Thanatos, seeing that Thanatos can be the manifestation of Ryoji's friendship with the protagonist during his form as Pharos.
