I Backstabbed the Golden Man from the Start and Became the Land of Light's Big Daddy

After transmigrating into the Ultraman universe, Rain discovers that he has become a low-ranking grunt in the Absolutian faction. At this moment, he has been ordered to guard the captured Ultraman Cosmos.

Watching the grunt captain swagger around, Rain awakens the [Ultimate Villain Backstabber System]!

As long as he betrays his faction and overturns the plot, he can earn incredible rewards!

“You really think Master Cosmos is a pushover?”

From the start, he turns around and hits the captain with an Absolutian blast, stabbing him in the back on the spot and unlocking [Ultimate Lifeform Origin]!

Ignoring Tartarus's furious warning, Rain seizes the space-time passage and plunges straight into the ancient Land of Light.

To evade the Gold Guy's pursuit, he puts on a white lab coat and disguises himself as a frail Blue Tribe scientist. But before he knows it, he and the young Ken and Belial have swept through the entire Great War, earning the title of the “Three Heroes of the Land of Light.”

Countless years later.

When the Gold Guy Tartarus finally opens a passage through time and space and leads his army in an attack on the Land of Light, vowing to crush the grunt traitor from back then,

he sees Rain, the highest authority in the Land of Light, standing on a high platform. Rain tears off his lab coat, unleashing ultimate golden light a hundred times brighter than Tartarus's, and grabs Diavolo by the throat with one hand.

Rain: “I hear you've been looking for me everywhere?”

Belial, standing nearby, stares in disbelief. “Holy crap! How can a frail Blue Tribe scientist fight even better than me?!”
