I Am Gherros, Equestria's Great Villain

In a Delta Force match, Yuwu was carrying the Tears of the Ocean when the Warden killed him. Enraged, he was approached by the System.

The System forced him to play the Warden and sent him to Equestria as a villain. From the start, he landed in the Everfree Forest. At this point, the six main characters were still fillies, and he had four underlings who would obey his every command...

(The story is on the dark side, with major changes to the original. Some original main-story elements will be added later, along with monster invasions, a cyberpunk style, and everyday life. There will be cybernetic modifications and gunfights, and characters may die in battle, but the protagonist has his own limits. I'll write whatever comes to mind. It's been too long since I watched My Little Pony as a kid, so the characters may include original changes. There is no heroine. The early chapters are rough and the writing is average. Most importantly, don't think too hard about it.)
