What's the most powerful and large machine depicted in anime? Stuff like the Steam Castle from Steamboy, things that really show the scale of the tiny humans up against a massive complex of pipes, gears, wires, and what not.
Well, Gurren-Lagann had mecha larger than galaxies, but it didn't do a particularly good job at depicting scale.
Of the more realistic stuff, the City from BLAME!, if you can consider it a machine.
Probably not that big compared to many examples, but I always think of the alien spaceship from Project A-Ko which is comprised of a bunch of classic anime sci-fi ships jammed together into a several mile long monstrosity.
I know it's a bad example, but the ridiculous air craft carriers in Girls und Panzer came to my mind.
he have a point through
Blame mention that they have to deplete resources and integrate Moon into it
It's sort of grotesque and pointless (justified pointless story-wise) and its still far more realistic
This is pretty much the best case scenario in that size range, I think.
Diebuster is in the same category of bullshit as TTGL but gets a special mention for her on-screen description.
The city ship in Horizon.
Can't find a good image of the entire thing that also provides a good sense of scale though.
If I tell you the truth, you won't believe it. So let's just roll with faggot.
Buster Machine III,
That's the moon in front of it. It's a mobile black hole bomb that use Jupiter the planet as the explosive/fuel/core.
It is build as desperate measure to blew up the galaxy (our galaxy) core when it become source of hostile alien.
granted Jupiter is compressed into the size of our moon before being put as the core of Buster Machine III but still...
it's on ridiculous scale but it's given with good enough story telling (in black and white for the intensity) as it depict last hope of men kind of thing.
lol, look at this guy trying so hard.
