leviathans> archangels does technically make sense. and though edgar killed to normal angels, edgars not a high leveled leviathan, so its perfectly possible that leviathans like dick or possibly the other are immune to an archangels powers ( or can unplug the archangels) and would eat them. this would explain why god never just had michael destroy them after he was made: because god thought there was a chance he wouldn't survive, plus if their blood is toxic to archangels then they have a weapon against them other than eating them where as angels entirely rely on their angelic powers, so logically it makes sense.
