User blog comment:T95/Top 10 Villains in Supernatural/@comment-1031724-20180519174502

I'd kinda put Azazel on the top of the list too. Even though I want him to stay dead. But, I have a thing for that kind of villain defeat, plus his death was one of the powerful moments of the show. Not that redemption isn't as good for some of them, especially cheering for it with Crowley and Gabriel.

Also loved Crowley, but I liked him better as an ally to Sam and Dean rather than a villain, even if he was usually the not-always-reliable ally (I remember being disappointed that he turned out to be evil in Season 6, though this was foreshadowed with him killing Brady's human shields). Same with Castiel. (Even working with Crowley he didn't seem much of a true villain until the last episode where he tore down the wall, killed Balthazar and the doctor from Purgatory, etc.)

Asmodeus was pretty cool in his own way. Part of this could be him having the same name as my favorite villain from Charmed, but even without that. He didn't have a whole lot of personality but felt like a compelling villain all the same.

I'd also put Dick on the list even though I didn't really like the Leviathans much. He was a kind of interesting one-shot villain, and one of the smartest too.

And Metatron of course, Curtis Armstrong. (Not Megatron, voiced by Ocean voice actor David Kaye, if you remember the joke when he was first mentioned in Season 7)

Of course Lucifer. As satisfying as his death was he was one of the biggest villains of the show, and he was entertaining at times as well.

Maybe Rowena too, though I didn't seem to like her as much when she was a villain, but once she started to become an ally like Crowley.

And I'm probably in the minority for this, but if we're counting villains other than BigBads, Ketch. I'd have loved to see him killed again but redemption works just as well with him and I'm glad they actually did something useful with bringing him back. He rescued Gabriel from Asmodeus, allowing Gabriel to turn him into Kentucky Fried Chicken extra crispy.

On that note, Gabriel too. Mystery Spot is one of my favorite episodes, and he actually seemed more fun when he was doing the tricks. Still loved him reformed and was sad to see him die, again (even though he faked it the first time, which they obviously hadn't intended back then).

That leaves one more spot. I'm tempted to say Mercury coz he's a speedster, or Loki coz Gabriel based his look and style off him, only Loki's more gangster-like. Or Ruby, but we liked her when we thought she was an ally, and she turned out to be working for Lilith the whole time. But, I'd probably say Meg. She was like the Mandy of Supernatural, always coming up unexpectedly, even turning into an ally at the end (though in Mandy's case this was a deal she made for immunity, and she survived at the end rather than sacrificing herself coz I don't believe Mandy would die for anything, she's in it for the money while Meg commits herself to causes, that's a major difference between the two).

So... Let me try to rank them.

Honorable mention to Ruby, Mercury, and Loki.
