Somewhere near Vale

As a Grimm Beowolf sniff the ground before chasing something in the woods but the wolf could kill the bunny the ground shook violently before the ground exploded the explosion was visible from vale as the dirt column rose to about 60 feet into the air as a massive black dragon with three heads rose up as the middle head mouth in its bottom jaw split into two as large barbed tongue sticks out hanging out as it roar a horrific roar into the sky above, as it red and black wings rose up and began flapping is wings trying to lift itself off the ground ready to cause some chaos.

(DesGhidorah: Des- means (Des)troyer and Ghidorah meaning that it's one of the Ghidorah-species members. But was modified (by who is unknown.) with the Dark Aether an weapon used by the "(Call of Duty: World at War) outer gods". Which means that gojira has to save the world soon from this monster. Also I just wanted a small "backstory origin" for your protagonist story caboose19 .)

In Vale

Civilian pov

Everyone panicked when a large dragon flew into the city and started causing chaos in the city as everyone were running away from the creature as I noticed that no Grimm were coming, they were probably just as afraid of this monstrosity of a creature. I started running, before a explosion happened behind me as I was sent flying before everything went dark...

3rd pov

DesGhidorah chuckled evilly in roars as a black smoke spilled out of the three heads as deceased people started getting back up but they weren't human beings anymore just mindless creatures wanting nothing more to feed on the living as Desghidorah far left head laughed evilly in Kajiu through many heard it and sent chills down their spines as the dead started walking again.

Many people started calling it the "dark Aether Hydra-Dragon (Desghidorah)" as dark crystals started forming around the city like an infection spreading.

(Just removed SpaceGodzilla and replaced it with Desghidorah and changed the white crystals to black.)

Meanwhile in the island

As Natsuki was dragging Gojira through town as many villagers noticed that something was different as the plants were growing healthier and at a much faster rate then normal. Until a framer noticed Natsuki and someone else, but couldn't make out the person features. Until the said person got closer as the old farmer put his glasses on and finally saw who was standing there.

The framer was surprised and horrified that their god was standing in human from and started bowing down speaking nonsense before Natsuki had to get her grandpa (from her mother's side) so stop making him look stupid. And once he stopped and apologized which Gojira accepted and he let them in the house. Before gojira could set into the house he heard the cries of innocent lives and a monstrous roars from far away. Gojira apologized before running off and towards the ocean where he dived in and disappeared under the waves where in the distance as massive dorsal plates set in three appeared in the distance heading towards the location where the monster alien not native from remnant would be exterminated for causing damage to the natural balance...

Up next (Chapter V| Gojira vs Desghidorah)
