Fauros, one of the trillions of gods that inhabited the cosmos, and the only one that almost managed to reach true omnipotence, was cornered and betrayed by everyone he once considered an ally, his greed, and thirst for power made even the most vicious of gods to become part of the alliance to exterminate him. In every meaning, the entire cosmos united in order to stop him from reaching ultimate power, and unfortunately for Fauros, they succeeded.
Fauros felt his own body crumbling apart as his existence dissipated into cosmic dust. However, right as he was about to disappear for once and for all, the voice of something or someone called out to him and bound a strange rule on his shattered soul

[Your soul shall be of use for me... Not every day do you find a disappearing almost-omnipotent god ready to serve you]

"Who's gonna serve you motherfucker? Come here and I will rip out your **** before then I ***** into your disgusting *****"

...

Fauros wasn't exactly very well mannered...

...

[Look at your tongue, even on the verge of disappearing you keep badmouthing everything in existence... -*Sigh*- Either way, I will now send you towards your new mission]

"What new mission you fuck, give me my body back so that I can kick that ugly face of yours"

[Make sure to make lots of good friends down there!]

"Hah?"

Thus, the evil god that once desired to control everything in existence was sent like that towards a very small planet in the middle of nowhere so that he could become...

...

...The sidekick of a Gary Stu in real life...

°°°°°°

The MC will be the Evil God by the way, just in case someone got confused.

Just had this idea, just testing how does it look for now... Maybe I will continue it if I like it.
I will also add more tags when I'm done planning completely the novel.
