Scarecrow. I was so excited to see him as his iwn villain in batman begins. So often he is ignored or shown as just a henchmen to another villain. But has always been my favorite villain in all of dc comics, he was even once a yellow lantern. Then lex Luther who was the orange lantern got jealous and stole scarecrows yellow ring.
I've always really like the character whenever I've seen him, but I had no idea his reach within the comic-universe was so wide! I shall have to do some reading because he sounds very interesting :)
He is amaxing. He truly doesn't get enough attention. The one where he was a yellow lantern was in the blackest night story arc with the green lantern. I haven't had a chancr to read it all, but I've done some research.
I watch this web series on YouTube (which is not letting me link) that I really like, it started out as sort if a cult DC thing and grew to a much larger fan base- but it has the Joker, Scarecrow, Harley Quinn, and lots of other characters featured throughout. It's called The Joker Blogs- some of the material is definitely mature, like 15 and up, so view at your own discretion.
