Ravager

Ravagers are a type of enemy seen in ''Mass Effect 3. ''The Reapers create Ravagers by mutating force-grown Rachni soldiers and augmenting them with cybernetic technology, turning the Rachni into bio-mechanical tanks. Two limbs on either side of the creatures' heads act as long-range artillery cannons and can destroy most foes with just a couple of shots. A large, swollen sac in the Ravager's mid-section contains a clutch of Swarmers: cyborg Rachni worker drones that have been turned into living weapons and will swarm and overwhelm whoever breached the Ravager's sac.
