The next official footage from The Amazing Spider-Man 2 will be the full-length trailer that runs before screenings of The Hobbit: The Desolation of Smaug in theaters, but new bad guy Electro (Jamie Foxx) was the focus of the short teaser trailer that aired at Comic Con this year. Shown strapped into some kind of device with his skin glowing blue as he soliloquized about being able to feel the electricity in his veins, Electro cut a pretty intimidating figure.

It’s not uncommon for movies, particularly sequels, to use a new villain as a key selling point in promotional material, and while Electro is only one of many villains from the Marvel universe who will be making an appearance in The Amazing Spider-Man 2, it definitely looks like he will be Peter Parker’s main foe for this installment.

What’s less clear is how exactly Max Dillon will acquire his powers and become Electro, since one thing that the teaser trailer definitely indicated was a deviation from the lightning accident on a power line that super-charged Dillon in the comics. Instead, Electro is shown taking his final form in the grip of the machine, and a new promotional still for The Amazing Spider-Man 2 offers a glimpse at what could be the guts of this mysterious hardware.

Between the lighting and the aluminium foil walls in the background, this set does look a little bit hokey, but it’s hard to tell when only seeing a small piece of it out of context. There’s a definite comic book aesthetic being generated by Foxx’s caricaturesque appearance and his surroundings that suggests director Marc Webb is happy to stray away from hyper-realism.

It’s also vague enough for the exact function of all these tubes and wires to be unclear. Is it an offshoot of the Green Goblin’s gene chamber? Who is the mysterious “Doc” that Electro referred to in his speech from the teaser trailer? Why would such a bottom-rung Oscorp employee be chosen as the subject for this experimental technology – or is the fact that Dillon is considered expendable the reason he was used as a guinea pig?

Despite how open Webb has been with teasers and hints – tweeting a different picture for every day of filming on The Amazing Spider-Man 2 – a lot of the fundamental questions remain unanswered. That’s just the way we like it, and hopefully Sony and Columbia will be able to keep some of the mystery going all the way up to The Amazing Spider-Man 2‘s release next summer.

The Amazing Spider-Man 2 opens in theaters on May 2, 2014.
