Its not the Attack Titan that comes to the rescue the day that the Colossal Titan attacks Trost. In fact its not a Titan at all, or at least not in the sense the people of the walls were led to believe. No it's something else, a living force of nature, a bringer of death and destruction, but also a saviour and bringer of hope. It's time for the Titans to face the wrath of Godzilla!

Now, it's up to them to save humanity, and wipe out every last titan that stands in their way.

Everything for a while felt safe within the walls, or so they thought as other Kaijuus started appearing out of thin air, so many destructive monsters lurking in the open world outside the walls...Nothing felt safe when they realize that Godzilla wasn't on humanity's side in their world, turning into a nightmare!
