Hello Fanwriters of GATE, this is Player 19 (at the time), although I have this planned since high school and wanted to write it out ever since I watched it. However, since I haven't write them out any time during 2019 and 2020 due to me playing games, being lazy, and being a student. In the end, I've decided to past this idea to anyone willing to write it out.

As far as I knows about GATE fanfiction is that most of the people write fanfiction of the gate appearing in different parts of the world, AU versions of Japan, and civilizations that fall in history. However, there isn't one like this idea which I found a game app that resemebles it too much and might considered to be a crossover if you like.

The plot is very much the same, but there is a possiblity that one of you writers might wanna included battles between the isekai travelers (my nickname for JSDF or anyone else) and the Gods/Apostles.

What makes this idea different is the very fact that the Empire will invaded the world where monsters are worshipped as Gods as well as ruling the human race like kings or queens of various countries in the olden days. I'm not native to how these monster rulers may be better or worse compare to all the leaders of the world of the past or the present.

Who are the Monsters Rulers (or Titans for short) and what/where are they ruled at?

The Titans is basically a power classification for a unique monster member of their own species to have the power that checks the Gods or even kill a god in their own right.

In the distant past where man went against the monsters that lurked in the night, it was a scary place for a human due to their enslavement to the Gods as well as the beasts that feast upon them. Until the Titans rose up and treated humanity fair as the Titans forced the monsters into living the first era of peace. This angers the Gods as they and their most faithful followers to fight against these unlikely of saviors. The Titans went to war against the Gods and managed overthrowing them as they were casted deep in the Earth. Since then, the Titans assumed the crown as the surviving humanity bow to them.

Although, there are many younger Titans that ruled small countries that there are at least 12 Titans that are considered the Most Powerful as their tribes of men and monsters have grew into the mightest nations in the face of their world. [These Titans could be inspired by the monsters or are the monsters from the likes of monsterverse, toho, etc.]

Here are some idea of who these 12 Titans are

Leviatori Rex: The Leviathan Dragon or the King of the Titans (Could be Godzilla), is by the far the most oldest and strongest of all Titans as he mastered the Flame of Destruction. He was fear among all, but kind only to the humans that worship him as he appears as the most smartest of Titans ever existed. Due to this, his kingdom have grown from a small island nation to all of the islands and oceans of the East as well taking large chunks of the nearest mainlands.

Nyxeos (could be Mothra): The Queen of the North is one of the kindest yet fierce Titan and appears to be hybird of intects that are elegrant and deadly in appearance. This often confused Titan have managed to steal the power from the Deities of Sun and Moon and used it to crave out the Northern of the Main Contient as her queendom as founded upon her nesting.

Nigrimoloch (rodan): The Fire Demon that is to said borne out of the Volcano as this king burned the entire Western part of Main Contient into hell like environment.

Megalosuchus (Angurius): This Titan is by far the longest titan ever existed and said to be born out the very land in the Southern Main Contient where the mountains reign. This creature lived by war and often blended since most of its body can reflect the trees and mountians. In the South, this Titan owned at least 95% as the remaining is owned by another Titan.

(The First Four Titans in the List are known as the Four Great Powers as well as they can be founded in my fanfic Reborn of a Faction/Nation)

Qhother (think of him as Baragon): This Titan was the first to descend to hell and overthrow The God of the Dead. Since then, He makes some major changes to the place known as Hella from becoming the place where all the dead souls have to live in never lasting torture and suffering to a prison for all evil souls and force to dug for basically everything Qhother values.

Ugdea (Biollante): This titan was inorganic in nature as she can controls everything onto the land. In fact, where Megalosuchus was about to invade her terrorirty, she uses the vines of the trees she was made of and turns her land into a small island.

(Be Creative with the Seventh Titan)

Beion (King Caesar): This beastman-Titan managed to keep the 5% percent of the South from Megalosuchus for a long time despites their sizes. Some says that Beion keep Megalosuchus from venturing into the mainland as if keeping the warlord out and keeping the more favorable Titans in rest of the mainland.

Phuntia (King Kong): Phunia is the Titan that is the opposite of the 1st Titan. Phunia lives in a large island in the form of a horseshoe in the Western part of the ocean.

(Be creative with the Tenth Titan)

Ydohr (Gamera in a way): Ydohr is the opposite to both the 1st and 3rd Titans. Ydohr's terroirty is the Western Ocean as he keeps Rodan from terraforming the mainland into the Hella and keep Phuntia from wandering outside his terrority.

Ovarae (Midguard Sepent): Ovarae is known as the Queen of the Seas, but her kingdom is the water surrounding the South mainland as she can contains Megalosuchus in his lands.

You can check whatever nation that the Empire is invading, but I prefer someone of the Four Great Powers as they held more sway as well as a gate appearing in their lands can lead all the Titans into the official Civil War as the Titans' hobbies are expending their sphere of powers.

True to be told, that I have forgotten about ⅔ of this idea since I was focus on my stories. I wish any one of you luck.
