A term popularized in the anime Dragonball Z refer to the ability of a fighter to harness their spiritual energy, sometimes measured with an explicity number mechanically with a visorlike headset called a Power Scanner. More roughly, they can be felt by some particulary skilled fighters. Some warriors are known to be able to adjust their power at will (minimum to their maximum power limit) and due to the complexity and skill of some characters, the moniker becomes less important as the series progress except in semantic discussions.

The term is less often used in the original Dragonball manga. More often, it's used prejoratively by anime fans to refer to the preceived excessive oneupmanship in some battle oriented anime.
