Ultraman: Hyper Zetton from the Start, I Am the God of Monsters

From the start, Li Tian transmigrates to the Gaia World. He thinks things will go just like in the novels: a golden finger, transforming into a Giant of Light to save the world, building a harem, and reaching the pinnacle of life.

But instead...

"This golden finger isn't right. Why is it called the Strongest Controller?"

"From what I remember, I seem to have Reiblood's bloodline. What the hell?"

Belial: "You brat, you share my bloodline. Why not join me?"

Li Tian: "Beat my weakest monster first."

Zero: "You want to control the Land of Light and seize the Plasma Spark Tower? You're still twenty thousand years too early!"

Li Tian: "Beat my weakest monster first!"

Monsters?

I will control them!

Ultraman?

I'll enslave them too!

From that day on, the universe lost a hero who saved the world and gained an emperor who ruled it.
