Crocbot

Robotnik sent Crocbot to act as his regional dictator in the southern hemisphere. For years, Crocbot maintained a moderate level of control over the continent of Downunda, though on occasion he would come into conflict with the Downunda Freedom Fighters, which would often spoil his plans. To ensure he had the necessary means to secure control of the continent fully, Robotnik shipped a zeppelin of SWATbots, weapons and other materials to Crocbot. Prior to its arrival, Crocbot mostly employed his machine flying dingoes.

Crocbot's first real defeat came when the Downunda Freedom Fighters received assistance from Miles "Tails" Prower, who had recently embarked on a solo adventure in his Sea Fox. Just as the blimp full of SWATbots and supplies arrived, Tails and Barby Koala attacked, disrupting its docking procedures and causing it to crash. Crocbot then attempted to escape in his nuclear-powered tank, but a bomberang from Walt Wallabee knocked the tank off course, causing it to crash into a crater (the former site of Echidnaopolis) and explode.

It was later revealed that Crocbot survived the ordeal. Although he maintained heavy structural damage, Crocbot managed to emerge from the crater and make his way to the ruins of Dr. Robotnik's supply blimp. From there he salvaged parts and created a tank for his lower body. With the remaining parts, Crocbot created a small army of Combots to follow his orders. With an army now at his disposal, Crocbot successfully caught the Downunda Freedom Fighters off guard and captured them, imprisoning them at the newly created prison camp.

With the Downunda Freedom Fighters captured, Crocbot set to work on mining precious mineral ore to power Dr. Robotnik's Ultimate Annihilator. During this time, Bunnie Rabbot and Antoine D'Coolette were captured in Knothole by SWATbots after Drago Wolf betrayed the Freedom Fighters due to Robotnik's bribery. Both Bunnie and Antoine were sent to the prison camp where they were placed in a cell, where Crocbot planned to interrogate each prisoner before executing them. Bunnie and Antoine managed to break free with help from Walt Wallabee and Barby Koala, and the four proceeded to liberate Wombat Stu, Guru Emu and Duck "Bill" Platypus.

Still wishing to rule Mobius alone, Crocbot secretly planted a thermo-nuclear time bomb inside the Combot Commander who would bring the mineral ore back to Robotropolis, hoping to wipe out Robotnik with the bomb. The device was discovered by Bunnie and Antoine however, and stolen for other purposes. Crocbot succeeded in shipping the ore to Robotnik via airbus, but just as the shipment departed, Crocbot and his Combot army came under attack by the recently rescued Downunda Freedom Fighters. Crocbot was again seemingly destroyed by the attacking Freedom Fighters, with his lower half was completely destroyed as a result of the attack. However, Crocbot managed to survive once again.

Having planted a post-hypnotic mind control diode on Duck "Bill" Platypus during his time in the Downunda Crater Detention Camp, Crocbot had Bill move his remains into hiding. Some time later, using Bill as an agent, he convinced the other platypus on Downunda to oppose the Downunda Freedom Fighters. Fortunately, Sonic the Hedgehog and Tails soon showed up during their hunt of Ixis Naugus. They discovered Crocbot hidden under a building, and disconnected him from his power supply, finally taking him out of commission.

Crocbot's remains were brought back with Sonic and Tails to Mobotropolis, which at this point was once again under the control of the Mobians. However, his remains would go missing after Kodos and Uma Arachnis stole Sonic's bi-plane in order to escape capture.
