Everyone Around Me Is a Protagonist? I Just Want to Take It Easy

The Protagonist Is a True Evil God: Nonhuman, Lovecraftian, and Simple-Minded

I'm looking for books like Horror Livestream: The Clingy, Lovesick Evil God Comes Knocking. The entity can take human form but should still be inhuman, with the human appearance simply making it easier to interact with people. It shouldn't even try to hide that it's an evil god. Lovecraftian elements are fine. Its way of thinking should be rather simple, so it's easy to fool. Really

The Protagonist Can Transform, Power Up, Turn Into a Monster, and Rampage 🤔

Nothing dumb or illogical.

Looking for Stories Where the Protagonist Is Someone Else’s Summoned Creature

The Protagonist Transmigrates and Just Wants to Be a Nobody, Watching From the Sidelines

The protagonist stays out of fights between the chosen one and the villain. One female lead, invincible, and cautious in how he acts.

Any Stories Where the Protagonist Transmigrates to the Modern City, Finds Out They're the Villain, and Immediately Goes into Seclusion?

There's no way anyone could hit the protagonist. People who hit the protagonist would never feel like they've landed a blow in their entire lives.
