The power levels of individuals are usually shown to the wearers through a heads-up display (HUD) on the scouters.Ĭharacters in the Fallout games use a similar device in the form of the standard issue Pip-Boy 3000. In the 'Dragon Ball Z' series, scouters are used by warriors in the villain Frieza's army to analyze the fighting abilities of their opponents in order to gain an advantage during encounters.
