How are AT Fields generated?
I'd have to agree. Explaining AT Fields is like looking into why angels explode into crosses. At the end of the day, Anno just liked the feel/sound/idea.
I know for sure that in EoE Asuka was able to use hers offensively to slice helicopters and shit.
This. Also everyone has one that holds them together which is why the tang is significant. Evas can exert them farther over reality because reasons. Also the lance is some kind of OP weapon that can go through them like butter.
AT fields, the Absolute Territory fields, or Zettair Ryouiki, are powered by the distance between a girls socks and her skirt. The closer the shoes/socks are to the skirt the more powerful the AT fields become.
Really those idiots in nerve need to get their crap together and just start removing all the shoes/socks and skirts from all the women and the AT fields will degenerate into nothing. Thus making the Eva units entirely useless yet saving humanity.
They're forcefield ego barriers, anything you see in the rebuilds is non canon bullshit fanservice so don't pay any attention to them
