Ultraman: The Light of Earth Is a Monster!

After humanity's betrayal and the plundering by the Absolute Clan, Earth's core was lost, and its light began to fade. In the midst of destruction, a light was born. Onierus inherited Earth's memories, refused to become an Ultraman, and fused with the genes of the strongest monster, killed by the explosion of Earth's core. On the road to recovering his mother's power and bringing her back to life, his first stop is where alien invaders of light seek to kill Earth's native guardian monster! "Invaders!" Onierus roared. Diga: Why does it feel like he's shouting at me? Lightning People: It's the light of Earth! We're saved! Humanity, give the sky back to the Lightning People! Gazort: Friends taste good! After human supremacy falls and the war between species ends, the Lightning People reclaim their skies. Humanity declines, the Lightning People rise, and Diga is driven back to Orion. Can Gatanothor destroy this new Earth civilization? P.S. The protagonist is firmly on the side of the Absolute monsters and will not be won over. The story may include the destruction of human civilization. The protagonist is a light of despair and destruction, and will drastically alter the original world. He has no Ultraman spirit.
