Ultraman: After the Fall, I Transform into Dark Tiga

[Ultraman] + [A heart turned toward the light despite living in darkness] + [The Ultraman spirit] + [An Ultraman imposter] (Not an invincible-protagonist story. The main character grows alongside his teammates.) Lin Zhao accidentally transmigrates to the world of Ultraman and gets the Tiga Spark Lens from the start. But to his surprise, when he transforms, he’s only the size of an ordinary human. It turns out the Plasma Spark Tower in this world’s Land of Light has been breached. Darkness rules the universe, Earth has been occupied by aliens, and TPC has fallen. The light in people’s hearts has nearly gone out, and Ultraman can no longer easily draw power from the light. If I can’t grow huge using the power of light, then I’ll gather all of humanity’s despair and make it my own. “If light cannot punish the darkness, then I’ll make my own body the kindling and despair the flame.” “I’ll walk through the endless night until I become the last ember of light.” “Let’s see whether despair devours me first, or I break through despair first.”
