Strongest Superhero Reincarnated in Another World

"A hero’s duty is to protect the weak… even in another world." Adam Vaelor was once Nuclear Sentinel, Earth’s strongest superhero—a living nuclear core with godlike strength. But when he sacrificed himself to defeat the alien warlord Zyrakk, he thought his story had ended. Instead, he wakes up in a fantasy world of swords and magic, reincarnated into a weaker body with only fragments of his former power. In a world where mana and aura reign supreme, his nuclear-based abilities are a complete anomaly—feared, misunderstood, and sought after by those who wish to exploit them. With bandits, monsters, corrupt nobles, and a rising demonic threat, Adam must adapt, grow stronger, and reclaim his lost power. But as he fights to uphold his old ideals, he soon learns that heroism in this world is not so simple. Will he rise once more as a protector of the weak? Or will the world’s darkness consume him first?
