Collider has published a list of ten anime series praised for having the most inventive or well-crafted "power systems" – the in-universe rules governing characters' abilities. The list judges each show on originality, creativity, lore, worldbuilding and how well the powers tie into the story, reflecting the importance such systems play in the action anime genre's popularity.

The article opens with the Dragon Ball franchise, credited with popularising the "Ki" energy system that combined martial arts with energy-based attacks, though the piece notes it now feels dated compared with newer, more inventive systems. It also highlights One Piece, which uses two intertwined systems – Devil Fruits, which grant bizarre and varied powers, and Haki, a strength that lets users counter them – and Soul Eater, created by manga author Atsushi Ookubo, as further examples explored in the ranking.
