The Riddler (Edward Nigma OR Nygma OR Nashton) is a fictional character, a comic book character and super-villain published by DC Comics, and an enemy of Batman. In live action, he was portrayed by Frank Gorshin and John Astin in the 1960s television series, as well as by Jim Carrey in the film "Batman Forever (1995)".
In 2005, a new interpretation of the Riddler debuted in "The Batman" animated series episode “Riddled”. The Riddler returned with a Gothic look and no one would have imagined the Riddler with long hair. Before this, the character was often depicted as wearing a domino mask either with a green suit and bowler hat, or a green jumpsuit.
Here's another close-up of the Gothic Riddler. Typical Gothic fashion includes black dyed and crimped hair, black lips and black clothes. Androgynity is common, with both female and male goths wearing cosmetics, skirts or high heels.
And here's the Riddler in comparison with Batman
