Scavenger

Scavengers are opportunistic pirates who follow the Locusts, a giant swarm of von Neumann machines that devour any habitats they encounter. The Scavenger scouts perform hit and run raids before the arrival of the mass of the swarm, and the majority of their fleet sweeps up any surviving ships once the swarm passes. 

Scavengers commonly have obvious and primitivist cybernetics, the better to frighten victims into submission. These cybernetics frequently take the form of weapons, from chainsaws to gatling guns, but their unreliability often produces less than spectacular results (hence the low damage potential). Scavengers are craven foes, preferring to use wolf pack tactics and quickly scattering in the face of any serious adversary.
