Union Academy: The Mightiest Warrior! (Male OC x Union Academy/Crossovers)

With the age of conflict now behind them, after everything the planet had to endure from the likes of Frieza, Cell, Majin Buu, and many more, the Earth is now at peace once again, thanks to the warriors that defended her for generations to come. Sadly, like everyone in life, our mighty warriors have moved on, though some in various different ways, such as Prince Vegeta who has ascended to become a God of Destruction, and Son Goku has passed away after living a fulfilling life. The Ki present in humans lying dormant have infused with the body, evolving humans and granting them Superpowers, however, it evolves the humans in many different ways, as some would have "Quirks", "Semblance", "Sacred Gears", and many more, as finally, after many generations, humanity is now more powerful than ever and Earth seems to be in good hands.

Sadly, although Earth has many heroes to protect it, there are those who wish to bring the planet to its knees, such as the man with too many quirks, the woman that is immortal, and the Devils that threatens humanity's existence itself! The Earth now more than ever, needs someone to save it! And that's where Nathan Kazuki, Earth's newest Saiyan warrior, comes into play, as this is the story of the Saiyan successor of Goku and Vegeta!
