Klarion Bleak
Only appearing in limited comic books and even more limited animated television, Klarion Bleak is just memorable enough to stand out among many other villains. His mannerisms are just hilarious. He acts like a snooty child, but when it comes to doing what he needs to, he has enough power to get it done. When a hero comes in his path and tries to stop him, he will turn up the heat with even more power! Klarion is just a fun character to watch how he reacts to situations, especially when someone actually rivals his magical prowess. I just wish he made more appearances.
Mr. Freeze
Given a very deep backstory thanks to the Batman Animated Series, Mr. Freeze took on a much more sympathetic persona. He's still freezing people left and right for materials, money or even control over something, it's all while he is trying to bring his wife back to consciousness and back into his life. His appearances in comic books and other medias really took away from his appearance in the 1992 series, and that's a very good thing, even if we got Batman and Robin out of the deal.
The Joker
The only reason he is not ranked higher on this list is because of the beating his character has taken over the past decade. He went from a chaos-loving laugh machine to an abusive maniac who had his face cut off because... honestly I don't care, that was dumb. Joker was always at his best when he had a plan to make some money but also cause some chaos and confusion for both the public and Batman himself. Even when Batman caught up to him, he had a surprise ready for him in some form or another. It was always up to the caped crusader to think his way through Joker's many traps and weapons. Once they thought darkening him to such psychotic levels was a good idea, his part in the comics became hard to read. Still, Jack Nicholson and Heath Ledger are both real points in Joker's favor.
Bizarro
The Bizarro version of Superman has always been an odd addition to any show he has been a part of. He's either a clone of Superman that went wrong or he's from a Bizarro dimension where everything in our world is backwards. Of course, the "backwards" theme is never really consistent, so asking why he's still super strong like his non-bizarro counterpart is pointless. Either way, my favorite appearance in the comics has to be the Superman and Batman series where he appears with Batzarro. It's a little dark, but it's a fun read.
Darkseid
One of the most reviled villains among Superman's rogue gallery. This new god has killed more characters than I care to count, including, unfortunately, Batman. He is very powerful, not only in his ability to use Omega Beams through his eyes, but also in his army of followers that worship him as a deity. He is always hungering for power, and for the Anti-Life Equation, which grants him ridiculous amounts of world breaking power. To be honest, he was a lot more fun before he obtained the equation. It was a lot better when Darkseid actually had weaknesses and a physical form. After he obtained ultimate power, he just lost all of his flavor.
Doomsday
From his first appearance imprisoned on a space rock, to his second battle with Superman, this was a powerhouse of villainy that had no remorse for anything. He is powerful enough to match Superman literally blow for blow. He is the villain famous for killing him in battle, even though he also met his end. Both of them resurrected from the grave and both of them met in battle once again. The sequel battle, I feel, was better and more structured than the first one. Not only did it have a more definitive end to a very awesome concept, but it made an already terrible menace grow even more horrific in his strength. They had to move Heaven and Earth to finally defeat Doomsday, and for me, that was the end of it. He was never given a proper translation to screen outside the Death of Superman animated movie.
Superboy Prime
Crisis on Infinite Earths was a mixed bag of a storyline, but one thing that shined out was the strength and utter brutality of Superboy Prime. One thing I hate about this character is that he killed Connor Kent, one of my favorite super heroes. However, the story of defeating this ridiculously powerful being was harrowing and forced the heroes to sacrifice a lot. Superboy Prime's real tragedy comes from the fact that he was just wanting to be real and wanting to do the right thing, he just didn't know how to do that. He was also selfish, arrogant and overly angry. I'm torn on this villain, but I have to admit that it was one of the best graphic novels I've ever read.
Mister Mxyzptlk
Who doesn't love a supernatural being that exists outside of time and space in a 5th dimension? Every single time this guy is one the page, something crazy happens and something random always comes out of it. Sometimes his plans make a little sense, sometimes they're just as a crazy as he is. Bat Mite may be a bit much like him as a Batman villain, but Mxyzptlk always had the market cornered when it came to rare but very fun appearances. His character was voiced by Gilbert Gottfried in the Superman Animated Series and it's a perfect representation.
Harley Quinn
One of the greatest characters to come out of Batman the Animated Series. Though, she may be a little over exposed at this point, we can still bask in her humble beginnings as just another Joker thug that pushed a cake into the police ceremony. Her wacky antics are a lot of fun, but when it comes to the more abusive moments in her and Joker's relationship, there comes a bit of a gray area that I tend to stay away from. This character is still a lot of fun when paired with Poison Ivy, but they sort of made her lose something when she went out on her own. Not only is she hardly considered a villain anymore, but now she seems to lack some sort of direction. She's both trying to get rid of the Joker theme, but really can't escape it when all is said and done. I'm not a fan of how this whole story progressed. It was a lot more fun when there wasn't so much deep lore and they just made quips at Batmans while robbing jewelry stores.
Lobo
The man himself! The bounty hunter who will stop at nothing to take down his prey. The best thing about him is his not care attitude. He's strong enough to take on Superman and has technology along with a hefty arsenal of firearms. Lobo rides around space on a motorcycle and looks badass while doing it. I'm not going to say I love all of his comic book storylines, but there are a great many of them that still remain my favorites to this day. This goes along with his amazing appearance in the Superman Animated Series, where he is after Superman as a bounty. Lobo isn't always the best character and some of his lore is a bit irksome, but overall, he's the most badass DC villain there is. When you need trouble, you know who to call. Virtua Rev!
