The King Xenomorph is the male equivalent of the typical Xenomorph Queen, albeit with many physical differences, such as long pincers on either side of the head and a large pair of insectoid wings on his back. The King possesses near-human intelligence and is the incredibly strong, stronger and faster than Queens and Empresses but smaller and comparatively less able than Queen Mothers.
The King is extremely aggressive, as well as territorial. There are 2 forms of Kings. The first are a form of protection, they come from Praetorians and must battle an entire hive, and its Queen, to assume its sole duty as the Queen's protector. He cannot kill the Queen, but if he is strong enough, then she will deem him worthy; if not she kills him. The second form is a Rogue; the first Rogue was a clone that a scientist tried to make of a Queen, but added testosterone and Human DNA. This made the King highly aggressive and destroyed everything in his path to go and kill the Queen who was shrieking at him through the hive mind, taunting him to come face her. The Rogue died quickly after its birth by the Queen, but not before the King ripped through marines, ship metal, warriors, and even smashing Praetorians; however this genetic mutation was absorbed through the hive webbing and integrated through the Xenomorphs genome. This means that a rogue Praetorian could molt into another Rogue and try to bring down the Matriarchy of the Xenomorph Species.
