The body of a Killer Bee Arrowgun is roughly diamond-shaped with short spikes on each of its corners. It is black, save for the rear tip, which is gold. The barrel is gold, somewhat wide and short, and ends in an arrowhead-like tip. The handle is dark gold and the black guard is lined by six black diamonds, each with gold edges. Its rounds are blue and the diamonds flash this color when Xigbar reloads. The sparks they produce are blue when striking enemies, but gold when striking anything else.
The Killer Bee, also known as the Africanized Honey Bee, is an extremely dangerous breed of bee that will attack in swarms with little provocation.
This weapon fires two rounds at a time, one from each arrowgun. The ground combo consists of four shots being fired two at a time and a 360° spin followed spin followed by Xigbar firing two more, slightly larger, rounds. The aerial combo starts by firing two shots followed by a backflip and two slightly larger shots.
