We know that an Evangelion needs a soul at it's center to operate normally, such as Yui being the soul of EVA Unit 01, and part of Asuka's mother being in EVA Unit 02. If the EVA Unit does not have a soul, then it would start bezerking like EVA Unit 00 during the testing phase of the EVA Series.

Now, for me, this raised another question, did the EVA Series (Mass production EVAs) use souls as well? Or were they "soulless"? Like how they were pilotless, and were "reliant" on the Dummy Plug system?

  • i removed the rebuild tag as the only hint of the Mass Production EVA's are in the preview of the last film that has yet to be released

  • @Memor-X, I included the rebuild tag because of the EVA 3.0+1.0 Trailer, mainly because of the scene where EVA Unit 08+02 is fighting the army of Mass production EVA Units. These Units look strikingly similar to the ones seen in the original manga and series, therefore would make sense that they would operate the same, hence me adding the tag

The only kind of answer for questions like this is "nobody knows for sure" (probably not even Hideaki Anno). While there is a precedence for souls being in an Eva's core, it's not definitively stated or implied that the mass production Eva's all have souls. We know in the case with Eva-03, that it's likely there was a soul put into the core that was "compatible" with Toji (Episode 17, Ritsuko and Gendo's conversation about the test at Matsushiro), perhaps his mother's? We also know that when the dummy system was activated in Eva-01, that there was a soul (Yui's) in that core, we know it can work with souls but we don't know for sure whether the soul is required.

One theory supposes that based on Kaworu's statement about the AT Field being the "light of the soul", which seems to imply that a soul is required to produce an AT Field. In the case with humans, the AT Field simply keeps the body together (otherwise we turn into orange goo) but in order to generate large/strong AT fields that can block weapons and make you levitate at an Eva's scale, there needs to be a soul in the core. Taking this into account however, we can see that none of the mass production Evas seem to display any ability to generate that kind of AT Field (though they do generate an Anti-AT Field later), so who knows.

If I had to make an unsubstantiated guess, I'd say there were souls there but we'll never know whose they were. One particularly sadistic theory, using the Toji + Toji's mother's soul in Eva-03 lead, says that the souls in the mass production Evas are that of the mothers of the students in class 3-A and that the bodies in side the dummy plugs are those of those students. There's not that much to back up such a theory, though.


Something that I forgot to mention, during the 2nd half of the End of Evangelion, during part of the instrumentality ritual the Mass Production Evas pierce open their own cores:

This happens during the sequence where the rest of humanity are getting turned into LCL and their souls released, which is in the form of a red glowing orb.

Some people believe that the piercing of the core is to release the soul that's inside it. In one couple of frames you can see that it glows red after the core is pierced:

So in a sense, this is their way of letting the human souls that are trapped inside their cores free in order to take part in instrumentality. Additionally, afterwards, the MPE's are all seen completely immobile, either because their role in the ritual is over, or without the resident soul inside the core, there is nothing for the dummy plugs to sync with.

  • I know, I know. But I thought that this question could be answered by the more "hardcore" Evangelion fans. I'm talking about the fans who dig up the web to find answers for questions like this, like old show scripts and other lore related material. But again, thanks for answering!

  • There just isn't enough to work from when it comes to the MPE's and their cores. Speculation runs the gamut and there's really no way of refuting or confirming anything. We've been having discussions about this since the early 2000's at the Eva Mailing List. Some people speculated that the souls were those of the defeated Angels. Just not enough info, even from extra canonical sources.
