Question: There is a scene I"m sure I've seen in a BUNCH of anime but I can only remember one example right now.
Group of people travelling along and pass through a crumbling city from a prior civilization. Ancient war machine detects movement for the first time in centuries and wakes up and attacks them.
The one example I can think of is Wolf's Rain, but I'm *positive* there must be others, as I can see fragments of images in my minds eye, but not more then that.
the mastodon instance at cybre.space is retired

Dammit, the scene is ALMOST on Youtube; this is the fight right AFTER the robot wakes up! https://www.youtube.com/watch?v=diaqpvV4yAQ
