Few anime tropes are as satisfying as watching a completely powerless, overlooked, or broken protagonist build themselves into an unstoppable powerhouse. Whether through ruthless training, forbidden contracts, or sudden supernatural awakening, the transformation from total underdog to overpowered force carries the best moments in shonen, dark fantasy, and isekai.
Below are 26 of the best anime where the main character starts at rock bottom and climbs all the way to godly power, ranked by the impact of their journey.
