Artifacts

In his search for money Robotnik discovered some ancient artefacts he believed to be from Mobopinchu, an ancient lost city. Putting them on sale he was distraught when Sonic, Sonia and Manic turned up at his auction and stole the goods. Sonic and Sonia took their item to be examined by the professors in the Mobian University, but Manic who had hidden his sold it to raise cash for the Underground. When Sonia and Manic told him the artefacts were actually worthless warheads from the last Mobian War Manic races after the man he had sold it to but was too late, he had already sold it to Bartleby. Before they could retrieve it from Bartleby, Sleet and Dingo kidnapped the art collector and took him to the excavation site to confront Robotnik. When the warhead exploded it destroyed most of Robotnik’s machines and activated several other warheads buried in the surrounding area, devastating the area completely. It's abilities are explosives and weakness are old and tempremental.
