was a term used to describe an enemy robot from the Sonic games, particularly in the early games. Inside each badnik is a helpless animal, which hops out when Sonic destroys the robot's shell. As a general rule, Sonic gains 100 points
from destroying a badnik, which doubles for each consecutive badnik he breaks open.
The term was dropped after Sonic Adventure's release, due to the fact Dr. Eggman had started using the E series of robots.
