Gojira could never have imagined that he would end up in a world not inhabited by humans. Yet after a single conversation with an apparent "Goddess" he and the rest of the TItans have been thrust into a world full of peace. And also bright and colorful creatures called "Ponies". With most of his kind still in hibernation in this new world, Gojira makes a life for himself in this new land.
That was all 50 years ago.
Now, Gojira has had plenty of time to integrate and learn about his new home. He has a mate and children, and is happy and at peace. But that doesn't last for long. Gojira can feel that things are changing, that the world appears to be getting ready for something. He has a couple of ideas but above all that he senses that trouble is coming. Whatever the danger, whatever is to come, Gojira is ready to take it head on. For although his time in Equestria has definitely changed him, he is still the King of the Monsters.
