Gインパクト・キャノン
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]]
