One of the most entertaining tropes in anime is the rags to riches of power. Some of the best anime series of all time star a character who could be considered one of the weakest in the whole world as they quickly become anything but. These characters start from humble beginnings,gaining immense power throughout the series and end somewhere either at the top or, sometimes, far beyond it.

While these characters become stronger than they could have ever hoped for, they started off in a much more vulnerable state. These characters are usually humble, even as the strongest in the world, because when the series started, they were too weak to change their own circumstances. With their newfound power, they look to change the world for the better, remembering where they came from the whole time and using that to inform how best to use their newfound gifts.
