14. Abaddon
Actress: Alaina Huffman
"“So go ahead and play hard to get, and I’ll peel off this “no demons allowed” tattoo and blow smoke up your (censored).” -Abaddon"
Few beings rivaled Lucifer in terms of terror. Abaddon is one of them. When she wanted something, she went at it aggressively. The scariest part about her is she was almost unkillable. Even decapitation didn’t work.
In the end, Abaddon’s arrogance was her downfall. She should have killed Dean when she had the chance.
13. Richard “Dick” Roman
Actor: James Patrick Stuart
"“You have that spark, that thing that makes humans so special. Not everyone has it, you know. Those people, they can be replaced, but people like you… are impossible to copy.” -Dick Roman"
You couldn’t have asked for a better one-season antagonist. Richard “Dick” Roman didn’t just use his monster abilities. The lead Leviathan took the body of a billionaire businessman to achieve his goals. It gave him more influence than being just a supernatural being.
Dick Roman was funny and smart, and his character was creative. Unlike most of the villains in Supernatural, the Leviathans hated demons and humans. This led to memorable interactions with Crowly, the Winchesters, and more.
12. Jody Mills
Actress: Kim Rhodes
"“Fine. But if she tries to show me her sticker collection, I’m out.” -Jody Mills"
Mary may have given birth to Sam and Dean, but Jody was their mother. She protected and consoled them in ways that they needed. Even after Mary returned, Jody looked after them. Without her guidance, the Winchester boys would have been an emotional wreck. Well, more than they already were.
Her spin-off (Wayward Sisters) would have been a hit. Unfortunately, it wasn’t green-lit. She has all of the personality needed to carry a show.
