THE RISE OF DICK
Yes they have made the "dick" jokes

Weaknesses: Less susceptible to the substances of Borax as his subordinates but it still works as an acidic against him, can be temporarily incapacitated with witchcraft, decapitate him and hide his head somewhere so that it doesn't re-attach itself; keep in mind that none of these methods can actually kill Dick or any other Leviathan, but they can greatly hinder them, can be killed by the bone of a righteous man soaked in the blood of the three fallen; the fallen in question being a Fallen Angel, the Ruler of Fallen Humanity (The king of Hell), and the Father of Fallen Beasts (an Alpha)

Notable Attacks/Techniques: 

Black Goo: by punching his enemy Dick can then inject a black gooy substance (a part of his true form) into the target, instantly killing it (has been shown to be lethal to Angels who are incorporeal in nature)

Consume: the very reason the Leviathans were locked away in Purgatory is because they pretty much were going to end up eating creation. all of it. Leviathans can consume everything, be it matter or souls, in fact they can even kill other Leviathans by eating them.
