Badniks were small robots created by Dr. Ivo Robotnik with the purpose of disposing Sonic the Hedgehog. Badniks also seemed to be sort of pets to the villainous tyrant, as all of the Robians and SWATbots were mindless pawns. Even when working together, the Badniks proved no match for Sonic or the Freedom Fighters. After the demise of Robotnik, several of the surviving Badniks continued to thrive on the Island of Misfit Badniks. However, after being discovered by Sonic and later the Forty Fathom Freedom Fighters the majority of them were compacted and seemingly destroyed.
The Badniks were the first enemies designed to be obstacles for Sonic like Dr. Robotnik (Eggman) in his classic Genesis games. When Sonic attacks them, a small little critter pop outs showing that Robotnik was using these animals for the Badniks.
Here you may feel to discuss about the Badniks and post pictures of Badniks I didn't show in the above images.
