History
Sleet and Dingo made contact with Evil Sonic who came to the Underground Zone searching for pieces of the Giant Borg for Robo-Robotnik. The two bounty hunters would mistake him for they’re local version of Sonic the Hedgehog and proceeded to capture him and bring him to Dr. Robotnik. (SSS: #10)

The two bounty hunters gave Evil Sonic to they’re employer. Evil Sonic would mistake the Underground Robotnik for Robo-Robotnik and give him all the pieces of the Giant Borg. Despite this, Dr. Robotnik had Sleet and Dingo taken away to a confinement cell to await robotization. (SSS: #10)

Sleet and Dingo would be seen later leaving the prison, Dingo asking Sleet if they would receive raises for capturing Sonic the Hedgehog. An aristocrat-disguised Sonia and Manic would successfully sneak beyond the two clueless bounty hunters so they could free Evil Sonic. (SSS: #10)
