Batman v Superman Leaked Trailer: 10 Things You Need To Know

6. The Riddler

After a shot of Bruce Wayne staring down his Batsuit (remember that there were rumours he might have retired at this point in his career because of the death of a close ally), Batman is shown standing in what looks like an abandoned warehouse as the lightning illuminates his surroundings. It's there than an Easter Egg can apparently be seen for the first time. Among the graffiti on the pillars is a very familiar looking question mark which is no doubt some sort of nod to The Riddler. It may have been added to the trailer just for fun, but is far too stylised to just be a regular question mark and not a reference to this villain. He probably won't appear in Batman v Superman, but clearly exists in this DC Universe.
