Hydrazona, a Terrifying Bacteria

Tokyo's night sky is hit with flood of headlights flowing through the veins of elevated speedways. But below, the ground is dark and gloomy. From a manhole, a large blotch of black liquid oozes out and starts climbing one of the giant pillars supporting the speedway. Where it touches, the steel rots and softens like a sponge. The speedway crashes down, cars tumble in heaps and burn. The black ooze is Hydrozoon, the micro bean monster that eats up metal. Skyscrapers and towers crumble down. Tokyo is in turmoil.
