Sony Pictures has released eight more images from The Amazing Spider-Man 2, including one photo that could hint at the villain -- or, rather, villains -- for the third installment of director Marc Webb's rebooted franchise: the Sinister Six.

In Marvel comics, Doctor Octopus assembled the original Sinister Six -- Vulture, Electro, Kraven the Hunter, Mysterio and Sandman -- to defeat their nemesis Spider-Man. Obviously, the effort failed, but the Sinister Six (or Seven, or Twelve) returned again and again over the decades with an ever-changing roster that has included Hobgoblin, Beetle, Shocker, Chameleon, Lizard and even Venom. The Amazing Spider-Man already boasts Jamie Foxx as Electro, Paul Giamatti as The Rhino, Chris Cooper as Norman Osborn and Dane DeHaan as Harry Osborn, so they're just two members short.

Opening May 2, 2014, The Amazing Spider-Man 2 also stars Andrew Garfield, Emma Stone, Sally Field and Colm Feore.
