This papercraft is Evangelion Mark.06, one of the new Evangelion units to be introduced in the Rebuild of Evangelion tetralogy of the Manga / Anime / Film series Neon Genesis Evangelion. First appearing at the end of Evangelion: 1.0 You Are (Not) Alone while still under construction at the Tabgha Moon Base, its first actual sortie takes place during the climax of Evangelion: 2.0 You Can (Not) Advance, piloted by Kaworu Nagisa. It reappears in Evangelion: 3.0 You Can (Not) Redo as an autonomous unit.
The final armored Mark.06 is a deep blue with yellow trim. The horned helmet, which bears a strong resemblance to Unit-01's, has a red visor covering the eye holes. The entry plug appears to be designed to provide a noticeably higher field-of-vision for the pilot. The Evangelion has shown to be capable of levitation while bearing an Angelic halo, which—in addition to the dialogue between SEELE, Gendo, and Fuyutsuki—hints at extremely potent capabilities. Mark.06 lacks an outlet for an external power source, implying an internal source of power.
Evangelion Mark.06 was constructed at NERV's lunar 7th Branch, Tabgha Base. It initially appears unfinished, with its body covered in a rubbery white material, and a purple mask covering its face, bearing the logo of SEELE with two dark holes at the top which marks under them that make it seem as if they were crying. The morphology of the head and neck is very similar to Lilith, although the more defined body, along with what appears to be a core visible beneath the fabric, is closer to a normal Evangelion. An IV-like device labeled BTB is connected to the Eva's left arm.
Later, the white cover is removed and the Eva undergoes the process of outfitting. The exposed skin on the head is dark gray while the body is tightly covered on a darker fiber that resembles muscle tissue. The mask remains affixed to the face, although it appears slightly modified, with the SEELE logo taking more space than before and the crying marks under the holes at the top removed. The middle part of the mask, approximately where the eyes would be, is hidden by a provisional covering held tightly by external wires as the helmet is readied for application. [Source: wikia]
