I meant one-on-one they are more powerful, thats why I mentioned that in Control the galaxy could probably fight them off.

The Leviathans where capable of hiding from the Reapers for millions of years, I'm sure they could easily hide from the Alliance. Additionally, without the Reapers hounding them after ME3, the Leviathans now have time to prepare for an invasion.
