We've seen what The Amazing Spider-Man villain The Lizard looks like in PEZ Dispenser-form, and now some concept art of the character may have leaked online.  It's possible this came from the production, but it's also possible that some fan just tweaked what they saw at Comic-Con and posted the illustration online.  As we said in our report on the film's Comic-Con presentation, The Lizard looks closer to the Batman villain Killer Croc.  This concept art shows a leaner version of the character, and the mouth is smaller and less toothy.  Again, if this is concept art, then it's just one of hundreds of designs that won't resemble anything you'll see on the big screen next summer.  However, it may be a good idea for Sony to finally release an official image of Spidey's new foe.Hit the jump to check out the image.  The film stars Andrew Garfield, Emma Stone, and Rhys Ifans.  The Amazing Spider-Man opens in 3D on July 3, 2012.Image via Spidermedia.ru.
