For the next couple Batman movies...

Name the best and/or most popular villains who have not yet been used in the new batman movies. So no joker, scarecrow, two face, Ras Al Ghul...

Someone mentioned killer croc already on the site so there is one..

ill add:

Bane Really cool, monster,  actually supposed to be very smart, unlike the 90s movie with i think it was george clooney where he was a stupid henchman for poison ivy.  I think he would be amazing for the new movies but they have to have his whole story in there which is pretty interesting, when i was a kid i read a novel with him in it. Pretty interesting.

Poison Ivy: i wouldnt use her in a current movie but ill name her cause she is a popular character. She adores plants, pretty much says it. lol.

Mr. Feeze:  Not sure i would use him either. Kindof cool, Arnold killed that character though for us. haha.

Penguin:  Devito did a good job with him in the 90s versions of Batman with Keaten.  With the new movies, i dont know if they would go this route.

Clayface: one of my favs... a must add to the new movies. He was really cool in the the cartoon way back in the day.

Catwoman:  I will be really pissed if they added a catwoman to the new movies. I never like catwoman and always thought the whole thing was stupid.

Riddler:  Jim carrey did it in the old ones... hmm. i think this could possibly work if they got the right actor for it and fixed up the character.

Azrael: Not a villain but he would be very cool in a batman movie. He took over for batman when batman was hurt and paralyzed by bain.  he went rogue though and Bruce had to retake control..

Abattoir:  Serial Killer..

When was the last time you were laid???  I'm guessin over a decade?

haha because i can remember these characters when i was a kid?   I wont even get into an argument with you man. Not worth my time...

I was always a big batman fan so I will play along too...

Clayface is a must... kind of like Sandman with Spiderman franchise.

Black Mask was always my favorite villian (next to Joker).  So interesting on so many levels.  Smart crazy like Joker.

Killer Croc would definately be cool but honestly I don't see them using anyone that is part creature part human.  The same goes for the Great White Shark (but it would be cool) or Man-Bat.

Dr. Hugo Strange would be also be another interesting one.

For the record, Bane is very intelligent and powerful.  It was Bane who broke Bruce Wayne's back which required the new Batman to be born.  Most people don't know this but it really is a toss up between Bane and Joke of who Batman's arch rival really is.  Just an FYI.

You had a good list though and BOL!
