Well, the Reapers themselves aren't the first of their kind, either. Creatures like the Flood and the Zerg are VERY much assimilationist monsters. Also, the Brethen Moons -- who have the added unfortunate of being abbreviated BMs -- operate on an entirely different philosophy than the Reapers.

Whereas the Reapers harvest advanced civilizations to prevent destructive wars between organics and synthetics (insert Terminator joke here) by becoming massive machine constructed by metals forged from baseline genetic materials; the Brethren Moons use the Markers to manipulate the dead tissue of life forms -- ANY and ALL life forms -- to make necromorphs to create huge masses of necrotic flesh with the intent of creating new Brethren Moons at the cost of the entire biosphere of a given planet, and are still very much organic.

Admittedly, the Reapers and the Brethren Moons are similar, but they are FAR from the same.
