User blog comment:Legionwrex/Did the Leviathan DLC really add a new twist to the endings?/@comment-5287758-20120901035748

The Leviathans aren't more "powerful" than the Reapers. Sure, one on one confrontation has the odds stacked against the Reapers, but the leviathans have no unified structure for warfare. All they can do is secure their own interests. They are very few in number and their only contact with the galaxy is through those bizarre artifacts. They have no "galactic invasion army" as such. They can be considered a fringe threat at best, for the moment. Furthermore, they have been exposed by the Alliance.
