Amp

Amps are enemies in the Mario franchise, appearing in Super Mario 64. They are present in in Bowser in the Dark World, Shifting Sand Land, Vanish Cap under the Moat, Wet-Dry World, Snowman's Land, Bowser in the Fire Sea, Tick Tock Clock, Rainbow Ride and Bowser in the Sky. They are black circles with faces that are covered in electricity, usually circling around an object. Mario will be shocked on contact, losing 1 wedge of life. They cannot be defeated. In the Nintendo 64 version of Shifting Sand Land, the pyramid contains Amps that instead of circling around an object, come out of a wall, thus not circling anything. In the DS version, they are regular circling Amps instead.
