CyclecannotbeBroken guy, I don't like scrolling that much. So, it's easier to tell you about my ideas of the Leviathans like this.

Evantually you get the option to stop them ( for the Leviathans) or to help them (Leviathans get mad at you)
 * First of all for the second trilogy (this idea is based on my Bounty Hunter idea), just another DLC where just past them, and having a little conversation with them, and that you have to take out some kind of terrorist operation, on their planet under water, which are having lots of high tech stuff. Their are some old and lost secrets on some secret location on somekind of water planet. You investigate as Bounty Hunter and try to convince these terrorist you want to help them. (free or low price money),this is how you go undercover.

The point is, there is something about this planet, which is more ancient than Protheans, but for some reason their is this some kind of recource like 'element zero' but one which is working as some kind of shield or kill/defense fuel against Leviathans. Do you know what I mean, it's kinda complicated I admit. But I'll try to explain, it's a bit like Superman and kryptonite I gues, same kind of method on Leviathans. Just this planet is filled with it, thats why Leviathans can't get to it, to investigate or to stop it. Thats why they ask you by using someone to talk for them, also you'll past them somehow.( you just see them swiming or somthing when you go them) The planet is not just ancient, not just a water planet, but also known as one the most largest planets of our galaxy (just recently discovered).

They can't touch or get close it. It even kills them, (works a bit like radiation), also as somekind of shield/barrier against their powers.
 * since the fact Leviathans are revailed, (just detail), anyway this terrorist organisation (there are hundreds of them), this one interested in science and ancient stuff etc. they have been studying about Leviathans and are aware of their danger and power. They have recently discovered this old water planet, which is filled of this new kind of resource which somehow is a weakness against the Leviathans.

Once you get in, the terrorist organisation, you'll join them with several huge submarines very deep underwater. Where you kinda find a lost world/city/civilisation (a bit like Atlantis), this lost world you have found (very intersting for terrorist scientist/docters, seems to be the lost world of which is known as the intelligence of the Leviathans time. Over there you'll find tempels, libaries etc.which are telling/explaining you more about their time,problems and conflicts with the Leviathans. You as Bounty Hunter have the ability to get flashbacks and to actually see it, which could be fun to play. You accidentally get back in time. Also you'll learn more about the Intelligence and the Leviathans. Which evantually leads that you have to fight the terrorist and get back. (the terrorist are having some problems what to do with this, so their will be 2 sides), Also you'll learn this is a very mysterious planet. Filled with a resource which actually may be able to end the Leviathans. But you won't have enough time to consider that. Just enough to make you curious. Also you discover why the Intelligence have hide here on this planet, to be protected and where they can build in secret their plans against the Leviathans and why.
 * MainStory of DLC (most interested part)

This was my Idea of a possible DLC for second trilogy (ME6)
