A Plasma Carbine is the standard armament of technologically advanced societies, used by the Kryptonian Warrior Guild on Krypton, as well as by the Parademons of Apokolips. A large majority of these rifles were passed down the caste for generations on Krypton, and like most Kryptonian technology, were built to last.
Fall of Krypton
The weapon saw much action during the short-lived Kryptonian Civil War, where General Zod and his forces used these weapons in a coup attempt to kill prominent bloodlines of Krypton's society, targeting members of the Kryptonian Law Council, the Sapphire Guards, as well as others loyal to High Emminence Ro-Zar.
Second Invasion of Earth
To be added
The weapon fires a burst of blue-hot plasma which burns through armor and flesh with ease. However, Plasma Carbines do not have as much of an effect on yellow sun powered Kryptonians as Superman was able to withstand a shot fired from a Kryptonian Dropship completely unscathed though he was still knocked to the ground.
