Evangelion Unit-0.0 (Evangelion Unit-00 Type II Kai: Area Defensive Unit [0.0EVA])

These units were built from the salvaged parts of the Mass Production Evangelion's External S² Engines and Evangelion Unit-00. Its armor sports the yellow and white color scheme of the non-repaired Unit-00 and is more bulky. It also is equipped with a backpack providing an unlimited amount of energy through an S² Engine reused from the remains of the Mass Production Evangelions, using the own spine, which would be troublesome later.

This unit is also somewhat unique in that it has been made in three copies, one for each Ayanami clone. The three units are designated as "Evangelion Unit-0.0 [Quatre]" (piloted by Rei Quatre), "Evangelion Unit-0.0 [Cinq]" (piloted by Rei Cinq), and "Evangelion Unit-0.0 [Six]" (piloted by Rei Six).
