Considering the Evas' size and weight, traditional powered flight (as observed in birds and bats) would normally be impossible, so the wings would feasibly be used in concert with A.T. They also possess large, fully retractable, mechanical wings (with an extended 'tail' piece), attached to their shoulders. Mass Production Evangelions with their wings extended However, unlike Angels, they do not utilize their organs for regenerative purposes (even though they theoretically could). The Mass Production Evangelions have all been furnished with S² Engines, eliminating the need for umbilical cable or internal batteries. In total, there are 9 Mass Production Evangelions, all completely identical to each other. Another major difference is with the back where the charging port has been entirely removed and the entry hatch has been shortened in order to make room for the large circular plates where the wings are stored. Looking down, there has been extra venting added around the armpit and looking to the side of the shoulder, the black pentagon is shorter and sharper than the other units.

Looking at the shoulders, a couple other minor differences can be seen. First, the MPE's do not possess any sort of shoulder pylon, just like Evangelion Unit-00 before its fitting. While similar in shape to the other Evangelion units, especially Evangelion Unit-02, there are a few key differences between them. The Mass Production Evangelions are mainly simplified Evangelion designs with its armor bearing mostly white color with black details in the arms.
