4-13 is a creture mutanted by genesplicer


4-13 was one of the early creations. It was a cross between a xenomorph, yautja and a bat. It soon broke out and killed eveyone and both unleased genesplicer and the othe creations. It soon made it's way to a colony on the planet fluna and began a campain of killing all their. Soon the remaining people, marines, and rookie fought back at it. Then El Blanco showed up and ate 4-13. But the genesplicer in it's dna was releshed and affected the area around the colony.
