Short for Gravity Impact Cannon. A large external cannon deployed to the pilot at their request which acts as a substitute for the Huckebein's Black Hole Cannon. It fires a gravitational barrier generated by the Gravicon System, which crushes the enemy to smithereens upon impact. When firing, the Cannon is connected to the Mk-II's crotch section, which is where the Gravicon System is located. Used mainly by the Huckebein_MK_II and the AM_Gunner when not docked with the Huckebein_MK_III
