Cody MacArthur Fett: I've always found the design of Eva-00's helmet/skullcap to be absolutely fascinating. One the one hand its design is extremely similar to the designs of other science fiction helmets like those worn by the UNSC Marine Corps, but on the other hand its got a massive green optics . . . thing on the top-rear of it. Seriously, what's the point of that thing?
thewayneiac: "What a big green eye you have!"
"The better to see you with..."
But seriously, there's a theory about the Evangelions' eyes. Unit-00 has one eye, Unit-01 has two, and Unit-02 has four. 1+2+4=7, the number of eyes on the Seele emblem. It is not known whether this is intentional, or what it would mean if it were.
