Instead, the bulk of the Reaper fleet remains hidden in dark space, beyond the Milky Way galaxy, and two Reaper-aligned parties handle the reproductive cycle's first phase: the Collectors and the solo Reaper known as Sovereign. The Reapers can't exactly patrol the galaxy in between cycles to go find the next species to harvest. How to Choose the Right Specimen for the Job It's a two-phase process, one that Commander Shepard interrupted in Mass Effect 2 when they fought and destroyed the human Reaper embryo in the Collector Base.

Thus, the Reapers are gigantic Collectors, and this process begins with the actual Collectors. In this sense, the Reapers become archivists, eternally preserving an alien race within their bodies while also saving that race from being overwhelmed by its A.I.

The Catalyst mention during Mass Effect 3 that the Reapers preserve the harvested race in a Reaper form. RELATED: Mass Effect: Being an Outlaw Vigilante was Garrus' Biggest Mistake - Here's Why That means choosing a race to harvest and collecting enough individuals to make the new Reaper. Each time the Reapers invade, they are preparing to make a new member of their kind. In that sense, each Reaper invasion is really a harvest, akin to driving a combine through a wheat field rather than simply exterminating people. This is why the insectile Collector race abducted so many colonists - they likely intended to harvest Earth itself to provide the raw material necessary to finish the human Reaper. Reapers "reproduce" when they harvest a vast number of people from a single alien race, and during Commander Shepard's time, the Reapers attempted to make a new Reaper with humans. Meanwhile, the Reapers are even closer to mimicking organic life, since their bodies are not, in fact, purely mechanical.Īs EDI explained in Mass Effect 2, a Reaper is made of melted-down people that are compressed and fused into a single machine, a Reaper thus Reapers are machine/organic hybrids.

The Geth can adapt and evolve in mechanical ways, and so can their programming. The Geth, for example, are considered a synthetic race rather than an army of robots, and thus the term "species" isn't exclusive to biological life. The Reapers are, in a way, a species, and the Mass Effect universe isn't afraid to draw serious parallels between organisms and machines.
