A Reverberating Carbonizer is an alien weapon. It was used by the unnamed alien chased by James Edwards in the beginning of Men in Black. He attempted to use the weapon, but it fell and evaporated upon impact. Later, Edwards pointed the gun out at Jeebs' pawnshop, which Kay punished Jeebs for. The weapon also has a mutate capacity, however it was not shown. According to Kay, it was often used for assassination purposes, causing him to deduce that the cephalopoid James Edwards encountered earlier most likely was undergoing an assassination mission and demanded from Jeebs unsuccessfully that he divulge who his target was.
