We knew that the Amazing Spider-Man 2, out May 2014, will feature both Rhino and Electro, and rumors ran that we might see a version of the Green Goblin. Two days ago a poster was released that confirmed we’d see some version of Green Goblin as well.

Today’s first trailer not only shows the Green Goblin (or whatever version of the character this is) will be playing an active role, but also hints we might also see two more classic characters, the Vulture and Doctor Octopus.

Here’s two screen shots of the Goblin:

And, here’s a screen shot of the hint of the Vulture and Doctor Octopus.

Those five villains would be a large portion of Spider-Man’s infamous foes, the Sinister Six. The first Amazing Spider-Man film featured Curt Connors aka the Lizard who has also been a member of the group (along with Mysterio, Kraven the Hunter, and more).

Guesses if we’ll see a sixth member and what would you want the line-up to be?
