We've seen a lot of different interpretations of The Joker on the big and small screens. Jared Leto will likely look to make the role his own rather than trying to imitate what others have done before.
I'm still unsure about his inclusion in the Suicide Squad (since he's never been a member in the comics and it just doesn't seem to fit his character) but I was quite curious how he might look as the Clown Prince of Crime.

I'm pretty happy with the way it came out, especially since this was my first attempt in ever doing anything like this. Seeing as how CBM is THE community for comic book enthusiasts, I'd love to hear your thoughts on my work and if you have any ideas as to how Leto's Joker should be portrayed in Suicide Squad and beyond.
