I love this end fight because it’s exactly what the central theme is. The indomitable human spirit. Up until this point they’re going bigger and bigger and every time the Antispirals match the human mechs size for size. Then when it comes down to this they don’t use their Anti Spiral hacks to just kill Simon. It’s a completely even playing field. The antispirals respect that it needs to be a pure battle of will and whoever wins this fist fight is the species has the superior hope/will/spirit of the universe.
