>>116355692If you give two randos a scarab and a ring, the scarab will win, yes. Scarab users require no training as their suits come with auto-pilot, and their weaponry can handle anything a basic Lantern grunt could put out, but the Green Lanterns horribly out scale scarabs at higher levels, plus their numbers are much greater and self replicating as each green lantern killed not only alerts the rest of them to the Reach's location, but creates a new green lantern from the nearby life forms.
The only reason the reach hasn't been wiped out is the GLC can't afford to spend all of their forces on chasing them down.
