Yes, and trust me, I included that in Alpha Vampire's page under powers and abilities heading, but ultimately, Leviathan, or ones like Edgar, wins (against the Alpha Vampire), at least. He would've beaten him.

Yeah, Cas is stronger than henchman angels, believe me. So, he would put more of a fight. In addition, seeing as ghost Bobby was able to toss Dick to and fro, Cas can, too.
