Initially Badniks, Bim and Bom may have been among a group of robots destroyed by Sonic the Hedgehog and infected with a virus created by Porker Lewis. If they weren't, the virus managed to spread to them before B.A.R.F. could arrive to delete the problematic files. Whilst they were working, neither B.A.R.F. nor a watching Trooper were able to stop Bim and Bom from escaping. The attack had scattered Bim and Bom's remains, making it impossible to repair them. Instead, Bert forced both rabbit organic batteries into one shell, whilst Cam removed the virus.
