WARNING 

MC is evil. He is going to enslave worlds and conquer planets. 

============
The Viltrum Empire, ever hungry for expansion, has achieved a breakthrough—an interdimensional machine capable of breaching alternate realities. Their first target? A world dominated by super-powered beings known as Quirk users. To lay the groundwork for conquest, they send a powerful Viltrumite warrior to infiltrate this society, taking on the identity of a Pro Hero and starting a family to secure his foothold.

Years later, his son, Soren Oda, is born—a child of two worlds with the blood of a conqueror and the memories of a past life. Reincarnated into My Hero Academia, Soren is stunned to realize the truth: his father isn’t just a hero, but an agent of an empire that seeks to subjugate the world. As Soren’s own Viltrumite abilities begin to manifest, he faces a harrowing choice.

With his father’s expectations looming over him and society’s greatest heroes unknowingly living under a growing threat, Soren stands at a crossroads. Will he embrace the ideals of heroism and fight to protect his new world? Or will he succumb to the might of his Viltrumite heritage and pave the way for the empire’s rule?

The line between savior and conqueror has never been thinner.
