The Graviton Beam Emitter (GBE) takes the form of an ordinary handgun, distinguished by a cross-shaped energy indicator at the gun's rear. Upon activation, the GBE emits a broad, perfectly cylindrical red beam capable of obliterating almost anything in its trajectory. While it hints at gravity-manipulating technology, the intricacies of its functioning have been lost to time, rendering reverse engineering impossible. The GBE fires condensed unknown energy, with the beam emitted literally pushing away the atoms of whatever is in it's path; the pushed atoms crashing back together cause large explosions, creating additional damage than the initial gravity beam. It can be discharged in two modes: either by individually pulling the trigger for rapid shots or by holding the trigger longer to generate a charged shot with a larger, extended energy beam. - Level 1 requires almost no charge and can be fired rapidly. At this level, the range of the weapon is 70 km. - Level 2 requires several seconds of charge and is notably more powerful, creating massive holes in it's target. If you can fire the gun on level 1 with minimum recoil, you are knocked backwards from the force of the kickback. - Level 4, the weapon will actually open up. In this state the recoil is so powerful and instantaneous that it will actually tear off the limb holding it. Due to its substantial recoil, firing it beyond level 1 is ill-advised for regular humans, with a level 5 strongly discouraged even for an Endbringer. (Tsutomu Nihei has stated that the effects of the weapon are so powerful that if it were to ever be fired at it's strongest from Earth's surface, it would have devastating effects on the climate and atmosphere of the planet itself.)
