[Purely evil protagonist + no conspiracy theories + no female lead]
Belial, the most evil Ultraman in the Land of Light, had been sealed in the Space Prison for tens of thousands of years. During that long stretch of time, his soul unexpectedly ended up on a planet called Earth.
When his consciousness returned, his experiences on Earth suddenly made him realize:
“Am I not a Reionics? Why not go capture some powerful monsters?”
He directly left the Space Prison in spirit form and found a temporary body to break the seal on his true body.
Unexpectedly, the person he'd possessed was also a transmigrator with a “Monster Training System.”
So he captured and trained monsters, laying a solid foundation for his monster army...
Raymon: My Gomora couldn't even withstand one move from Eleking, one of Belial's underlings...
Zero: What the heck! Why is even some random Gomora under Belial so hard to beat?
Alien Empera: My Dark Empire! I should've killed that brat Belial back then!
King of Ultra: I shouldn't have just sealed Belial away back then...
