There are a few scenes that come to mind.
1) In Akira when all the stuffed animals start bleeding that milk looking stuff and start becoming deformed man that was
creepy.
2)In episode 18 (i belive) of evangelion when the new evangelion turns out to be an angle but Shinji won't attack
it because it has his classmate Toji in it. So Gendo activates the dummy plug and I was seriously taken aback by the
sheer brutality of how unit 01 tears the angel to pieces.
3) Also in End of Evangelion when Asuka and Unit 02 are torn to pieces by SELEE's eva's. Damn that is hard to
watch because I actually really like Auska :(
