Amp

Amps, also known as Electro-Chomps, are small, electrified metal balls who have appeared as enemies throughout the Mario series.

Alternate Kingdom
Amps are set to appear in Alternate Kingdom as one of the game's uncommon enemies. They will have a similar role to that of the New Super Mario Bros. games. They serve as the members of the Blaize Army. They often appear in airship and dungeon levels, such as castles and fortresses.
