Favorite Batman Villians

I am totally a Marvel fan. I have never cared too much for DC comics or movies.  The one exception being Batman.  This is probably because my dad is a fan of Batman but I am not sure.  I also grew up watching all the movies staring with Tim Burton's version in the 80's.  Some of the villains are awesome too, my favorite being Harley Quinn.  Here's my list of favorite Batman villains including Harley.

Harley Quinn
I have always been a fan of hers and I have no real reason why.  She's just so awesome and crazy.  Perhaps I like her since she is a psychologist?  I am still hoping for her to show up in Gotham.

The Joker
I never really appreciated the Joker until The Dark Knight and Heath Ledgers portrayal.  He is Batman's biggest villain, so one has to like him for that.  The guy is pretty much crazy and willing to do anything.

Scarecrow
I honestly never knew who the Scarecrow was until Batman Begins.  Again, he is like a psychologist so I like that.

Poison Ivy
Another one I have always been drawn too.  I seem to like the female villains-Girl Power.  Poison Ivy is also interesting with her plants and all.  I think the first time I saw her was in Batman Forever.  Not the greatest film but still introduced me to this great character.

Lady Shiva
For those not aware, Lady Shiva is an assassin and a fighter.  She is pretty much a bad ass.  She is also sometimes an ally of Batman
