Phalan 2752

Phalan 2752 as visualized today.

Phalan 2752 are a self-replicating, hyper-intelligent virus that share a single hive-mind.  Each individual is actually constructed of 2752 single-celled parts that function as one entity.

Shortly after gaining sentience, the Phalan 2752 killed its creator, began replicating, and over-ran their planet of origin, destroying every living thing they encountered.  They continued to perfect their genetic makeup, making themselves more resilient to harm and and increasing their already vast intellect.

The Breed discovered them accidentally when one of their scout ships crash-landed on the Phalan 2752 homeworld.  First contact did not go well.  Luckily, the Breed managed to contain the Phalan 2752, and their homeworld was quarantined, one hundred full armadas stationed around the planet to make sure not a single Phalan 2752 made it off world.  Because of the hive mind shared by the entire race, all it would take is the escape of a single individual, and they could very well overtake the entire universe.
