Irken Repulsors

Irken repulsors are a special type of fuel engineered for the propulsion of space vessels, belonging to the Irken Armada. These repulsors are extremely efficient—capable, for instance, of consistently sustaining a voot cruiser for over six months in a single outing. Vessels can last a very long period of time with this technology, though with so many ships in the armada, every so often a few of them leave extra repulsors behind on their parking structure planet, Blorch. As it happens, this turns out to be a helpful factor in the reconstruction of the crashed Death Egg, when Waluigi comes across a few leftover repulsors in the "Dimension" saga; this provides Shadow the Hedgehog, Wario, Waluigi, and the E-series robots a welcome increase in their chances of getting off the now-deserted planet they have been stranded on, and back to Earth as quickly as possible.
