SWATbots

The original SWATbot model was created the year of Dr. Robotnik's coup. Armed with laser pistols and rifles, the SWATbots proved extremely successful against any of the early resistance forces. Within a matter of hours, the SWATbots had managed to take over numerous key points of Mobotropolis and rounded up thousands of Mobians, which would be roboticized shortly after the coup's end.

For the next ten years, SWATbots were used as the primary military force of Dr. Robotnik's army. However, as the various Freedom Fighter groups began to form and oppose Robotnik's reign, the success of the SWATbots gradually decreased. By the time the Knothole Freedom Fighters were teenagers, the original SWATbot model had become obsolete. During this time Robotnik turned to creating other robot models, such as the Badniks, E.V.E. and later Combots.

As the SWATbots abilities to stop the Freedom Fighters dwindled, Robotnik began putting them to other uses, primarily as a labor force. When Robotropolis was essentially destroyed by Mecha Sonic and Mecha Knuckles, Robotnik had the SWATbots rebuild the ruined city. When Robotnik went onboard the Death Egg and left Snively in charge of Robotropolis, the latter changed the priority of the SWATbots from defending the city to acting as his personal servants and reshaping the city as he saw fit.

Dr. Eggman switched from using Shadowbots to updated models of SWATbots and Egg Pawns. When Sonic the Hedgehog returned from his year-long absence in space, SWATbots of various designs were seen holding Geoffrey St. John and Hershey Cat prisoners. After the couple was officially married, the SWATbots were moments away from executing them, but were soon destroyed by Sonic.

When Dr. Eggman was preparing a three-pronged offensive against the Kingdom of Acorn and the United Federation, he dispatched a large number of varied-modeled SWATbots to the dome shield surrounding the nuclear irradiated remains of Robotropolis in order to destroy the shield and cause the spreading of harmful radiation throughout Mobius. However, the garrison at Fort Acorn comprised of the Mes Braves Battalion and reinforcements from the Chaotix, Amy Rose and G.U.N. resulted in the entire SWATbot army's destruction.

The SWATbot models were primarily decommissioned after the failure at Fort Acorn, though some of Eggman's Shadowbot-based SWATbots remained on Angel Island to support the Dingo Regime.

Eggman had already begun to switch over to the new Egg Pawn model the year before, which became the new ground forces and labourers for the Eggman Empire following the SWATbot's decommission.

Despite three years having passed since the death of their master Dr. Robotnik, some of the original SWATbot models continued to exist, sparced throughout Mobius. They, along with a few functioning Badniks, became employees of Mammoth Mogul when he took control of the Casino Night Zone.
