I rather like this one out of all my ranged weapon art for Galaxy Hunters. It looks like a pistol with bunny ears! I played around with various pistol silhouettes before I came upon one with some sort of stock connecting the grip to the back of the gun. I guess the metal tubes on the top contains different ammunition so that the pistol can switch between various ammo types when facing different kaijus. Since the pistol uses so much energy, it has to be connected to a battery pack or to the mech. I am a fan of Evangelion, so the battery plug that connects to the EVA units had some influence on this design.
