Catwoman gets honorable mention because she's 1/2 hero. UGH i love all the Bat villains, I didn't even get to list Poison ivy, Scarecrow, Ras Al Ghul, or Clayface.  But NOT the Penguin...i hate the penguin

My list does not include Joker not because i don;t love him but because it is like when one talks movie directors Speilberg is never on brought up because he is just a given above all others.

1.Two-face

2. Madhatter

3.Ra's Al Ghul

4.Dr. Arkham

5.Riddler

1. Joker-not just Batman's greatest enemy but one of the best villains ever

1. Joker -no explanations needed
2. Carmine Falcone -I'm a sucker for Godfather and he's the closest thing to a Don Vito
3. Lady Shiva -Anyone that can surpass Bats in H2H is a certain winner in my book
4. Bane -Genius + Brute Force = Broken back
5. Scarecrow -fighting fear with fear. Awesome!

 1. the Joker

1. Joker
2. Ra's Al Ghul
3. Poison Ivy (as long as mind-control isn't involved)
   
4. Scarecrow
5. Two-Face

1. Joker

Ra's al Ghul
Bane
Poison Ivy
Joker
Clayface
I dont consider Deadshot,Deathstroke,Prometheus , Lady Shiva,Catwoman etc to be bat villians or i'd have mentioned them too.

1) Ra's al Ghul 2) riddler 3) joker 4) scarecrow 5)penguin

1. The Joker

1. The Joker
2. Two-Face
3. Ra's al Ghul
4. Catwoman
5. Mr. Freeze

Well, my list would be: Joker, Harley Quinn, Catwoman, Poison Ivy, and Two-Face...but that seems boring somehow. So I'll give the next 5: 
 

1. Mr. Freeze - I love him more in TAS and Batman: Beyond more so than in the comics, though. He's far more tragic and far more human in those depictions.
2. Thomas Elliot/Hush - He's proving himself to be one of Batman's most capable villains.
3. Scarface - I love the concept behind him - that even the most innocuous and absurd thing can still garner power in so long as their are people willing to serve him in exchange for some money and power themselves. He lends a lot of plausibility to the otherwise completely implausible villains in Batman's rogue gallery.
4. James Gordon Jr. - Very scary. Very intriguing. Watching where his character is going.
5. Carmine Falcone - I just kind of always considered him a tragic figure - a man who was in over his head.

1. Pyg - He's just way too grotesque for my taste.
2. Roadrunner - Come on!....
3. Tweedledee and Tweedledum - Typically don't care for perversions of my favourite children's book, Alice in Wonderland. (Though I do love The Carpenter)
4. Mad Hatter - See above.
5. Doctor Hurt - Still trying to wrap my head around who he is exactly...

This is gonna be hard but
 
1. Poison Ivy
2. Riddler
3. Ra's al Ghul
4. Joker
5. Mr. Freeze

1. Two Face
2. Ra's Al Ghul
3. Joker
4. Red Hood
5.Hugo strange

@entropy_aegis: Well, then I'll have to disagree with your assessment of Hush. I think he's slowly become forgotten since Dick became Batman, but few other villains really cut at the very heart of the Dark Knight like he does.

Though i am surprised by the amount of love Riddler,Two-face and Freeze are getting.Guess animation can go a really long way.

1. The Riddler
2. Scarecrow 
3. Killer Croc
4. The Joker
5. Poison Ivy

Ra's could have done that,Bane could have done that,Joker could have done that,they just don't care.He wen't after Selina knowing he could'nt do jack to Bruce.Pretty dishonourable guy. Either way i feel Between Deathstroke,Bane and Prometheus there is no need for Hush,Wraith and Black Mask.

Ra's, Bane, and Joker weren't Bruce's best friend as a child. Nor did they grow up filling in Thomas Wayne's shoes by joining the medical profession. Nor did they rip-out Catwoman's heart. Other villains Batman but Hush attacks Bruce Wayne.   And of course he acted dishonourably - he's a villain.   I don't know much about Prometheus or Wraith, so I can't comment on them. And I don't think that Deathstroke is strictly a Batman villain, so I think he's not particularly relevant, to be honest. And I have to agree about not caring much for Black Mask, much less Black Mask II, but I don't think that he's rendered obsolete by Deathstroke, Bane, or Prometheus as much as by Two-Face, The Penguin, and major crime families of Gotham.

You mean they were'nt magically shoehorned in to Bruce's past?They've known Bruce's secret for years before Hush came along(who only found out due to Riddler).And Ra's does have a background in medicine,Joker and Bane have tampered with chemicals as well. Both Ra's and Bane have had Selina at their mercy(Legacy).But she still managed to worm her way out.It's an insult to both Catwoman and the villians to be bested by someone vastly inferior. Penguin is the only decent character amongst the gangsters,Mask and Harvey are one trick ponies.

In order : 

1. Riddler
2. Two-Face
3. Black Mask
4. Scarecrow
5. Joker

1. Joker.
2. Dr Hurt/Black Glove.
3. Two Face.

Of course Bane and Ra's know Bruce's secret, but when did Joker learn about Bruce? (I'm genuinely curious about that.) Yes, Ra's does have a medical background, but he doesn't represent what Bruce would've become had he not been Batman. Whither Hush is "inferior" or not should be based upon his actions, and he managed to devise a plan that nearly destroyed both Catwoman and Batman by taking advantage of their relationship. And that is not a surprise because part of Hush's premise is that he is superior strategist than Batman, which says a lot.   Also, it's just not part of Joker, Ra's, or Bane's M. O. to surgically remove organs (although, I guess anything is possible as far as Ra's is concerned.) That sort of plot-device should only be used by Hush, really. I personally think that Black Mask is something of a no trick pony, but I think that Harvey Dent is rather complex and interesting and Penguin is usually interesting, but he's not my favourite villain and he's certainly not the most threatening. (He's just a giant cog in the machine of corruption that whiddles Gotham down, day by day.)

1. Joker- The Bat's archenemy. Crazy, hilarious, and totally evil. You can't get any better than that 
 
2. Two Face- One of Batman's most iconic foes. A very unique villain with a cool gimmick, and a great backstory to boot. 
 
3. Scarecrow- Also a unique villain...He can get into Bat's head. His fear gas is very original and makes for some great moments.  
 
4. Riddler- Riddler is one of the few Bat enemies that challenges Bruce's intellect. He can be a great threat when he needs to. 
 
5. Bane- One of the more intimidating villains. He was one of the few who actually BEAT Batman. That alone gets him in the top 5.
