Ultraman: More Children, More Blessings, Becoming Dark X

After transmigrating to the world of Ultraman X and getting bound to a more-children, more-blessings System, Gong Yuan is overjoyed. From the start, he nearly awakens Ultraman Noa, one of the Mysterious Four Ultras.

Unfortunately, the System determines that he hasn't had enough children, then awakens Dark Ultraman X instead.

And so, a strange Ultraman appears in the Ultraman world.

Belial: "That guy has pure dark power radiating from him. Why is he wearing headphones and running toward the forces of light?"

Zero: "Even though Senior Gong is covered in darkness, I'll still treat him as my rival. I have to defeat him."

X: "We're both Ultramen, so why is he so ridiculously strong? Damn you, Senior Gong!"

Z: "Damn it, we're both using Cosmic Fist, so why did Senior Gong kill the monster with one punch?"

After missing out on Ultraman Noa, one of the Four Ultras, he takes the place of Dark Ultraman X.

From then on, the Ultraman world has one fewer enemy Boss and one more dark, scheming man whom the protagonists both love and hate.
