The Real GhostbustersEdit
Located on the far wall opposite the door in Egon's laboratory, the Dimensional Inverter is one of the most unstable pieces of equipment. Egon has had to constantly put out small fires with a fire extinguisher while performing tests on it.  Victor messed with the control panel and caused a power surge in the Firehouse. Slimer attempted to intervene but he was electrocuted and blamed instead of Victor. Egon threw the switch down and turned the Inverter off. During the Land of Lost Objects case, Egon got it in working order more or less. He chose to remain at the Firehouse and monitor a dangerously high P.K.E. surge while the others investigated a call from Brooklyn.
Egon managed to get the Dimensional Inverter working again. While performing a test run, he unknowingly fried Slimer's Stay Puft Marshmallow Man doll and a Flex-O-Man Comic. Egon apologized but continued to perform more tests to make sure the Inverter was perfect.
