I would be scared to death if I ran into this evil version of Batman in a dark ally. Hell! I'd be scared if I ran into him at the beach in the middle of a nice sunny day. This character design comes from CGHUB artist Stepanchikov, and it's utterly terrifying!
The image gives us a great glimpse of what The Joker would look like as Batman. This was the winner of a art contest for superheroes turned villains.
