GD-18 "Harseesis"

The GD-18 "Harseesis" is a UGI Secret Weapon that is capable of detonating Kalomite crystals. This weapon was kept under wraps and only 8 people know of its existence one of which is Erex Malren. The weapon uses Kalomite crystalline structures that are submerged in Red Matter. About 18 pounds of this Red Matter and 20 ounces of Kalomite created a super weapon that when tested in a dark area where most Federation ships have never been. Instead of the ZR-51 Region Busting power, not only did it vaporize everything in its path it created a super black hole that  sucked everything within 8 regions into it before collapsing in a matter of seconds. A weapon this powerful was going to be aimed at the Federation at one point when the UGI felt the Federation wasn't for the UGI and would declare war. Erex Malren stated to never use this weapon unless it was out of absolute need. Its power could take out almost everything in the Alpha Sector if detonated on Earth its range would reach where the Delta Sector begins. And one other was made with almost 90 pounds of Red Matter due to the UGI's ability to mass produce Red Matter the Federation at the time wasn't aware the UGI could utilize Red Matter into Firearms. (Hence High Impact Plasma is made from molecules of Red Matter. One molecule per cartridge provides the stopping power. But the Federation at the time coulnd't figure out how to strip the Red Matter Nucleus from the the cell.)
