This troper used this trope with Viandas/Evershadow Genesis. It was made as a Darker and Edgier version of New Dawn, a very idealistic little Sentai book. Viandas deals with such themes as the nature of existence, the truth of feelings, and near every character has a negative feature. TheHero is a Type Four AntiHero at first and is quite

very complicated plans all connecting and forming a very complicated web. Even the lowliest demon mook probably has an origin derived from HighOctaneNightmareFuel towers where horrible, horrible things happen. Oh yes, and then our lovable hero becomes immortal and lands in another series of Xanatos Gambits. You would think becoming a PhysicalGod would do good things for Johnson, but no...it only means he can now be attacked by other Physical Gods, and the process of becoming such a being led to the opening of a gate that let TheEmpire into the still volatile world Johnson calls home...
