This is a question about the original "Evangelion" and the follow up "End of Evangelion". I haven't seen "Rebuild of Evangelion" yet.
In the series, it seems clear that the EVAs are cybernetic constructions.
So here's my question/conjecture (which may be a spoiler): are the prototype EVAs clones of the childrens' mothers, somehow mixed with the first angel's DNA?
Unit 0 and Unit 1 are seemingly both related to Shinji's mother Yui Ikari.
Asuka seems to say that Unit 2 is her mother during the final fight
We never learn much about Unit 3 before it is possessed
The mass production models all seem to be clones of Kaworu
Is there any canonical support for this conjecture?
