Nerocite is a chemical that is used by the Xlyvanian army to run their vehicles. Nerocite was also used by the Old Xlyvanians the Iron Legion as a weapon. The Iron Legion's Bazooka and Flame Vets both use pressurized forms of Nerocite. The screaching sound the Flame Vets weapon produces is said to drive it's user insane and the pressurized Nerocite of the Bazooka Vet's Slayerund Shot could light the dark skys of Xlyvania red.
