I Became the Next Host for an Alien Monster

Any Containment-Object or Anomalous-Disaster Apocalypse Stories? No Stories Where Humanity Has the Upper Hand

In order of importance, from most to least: 1. Humanity must be at a disadvantage! Lots of tragedy is fine. 2. Only a few anomalies should be intelligent, and they should all be conceptual in nature. 3. The golden finger shouldn't be invincible. It can be useful, but it can't be ignored. No rebirth or prophecy. 4. No CP.
