Etrigan

Is there any kind of connection between Etrigan and Trigon?

How powerful is Etrigan in Prime Earth? Is he still strong enough to take on Superman?

I just heard from someone that there will be a Justice League Dark movie soon, but I found out after it was canceled. Do you have any news if you really will have it? If so, do you know what the script will be and who the current members will be?

Just a thought, but could it be possible if Jason Blood is a fable?

What with being a knight and allies with King Arthur and Merlin and all...

I finished reading the Demon by Jack Kirby. So I wanted more comics featuring Etrigan.

Any recommendations?
