The "Ant-Man" movie has named some of its villains. While there would be some minor changes, most of them come from the classic rogue's gallery of the diminutive hero.

The bulk of the rumors come from the website JoBlo. They are also the source of spoilers from other Disney movies.

Their take on the villains:

"The main villain's name is Darren Cross who, in the comics, runs Cross Technological Enterprises, a competitor company for Stark Industries and Oscorp. His cousin is the villain known as Crossfire. It's unknown if this role will be played by Patrick Wilson or Corey Stoll. He will have a suit with a similar feel to Ant-man's but more miltary style, yellow and black in color, and with a tendril-looking apparatus coming off it's back (like with Agent Venom). It's to note that in the comics Cross looks more like a pink Hulk, so there may well be some merging of attributes from other characters for this role or multiple villains at that (Yellowjacket, perhaps?)."

An analysis from Badass Digest confirms Yellowjacket, but raises an interesting point:

"The villain in Ant-Man is Yellowjacket. You'll note that this is way outside of the comic canon, as Ant-Man Hank Pym himself was Yellowjacket for a while - he had a bunch of different super-identities, with Yellowjacket being one of the edgier ones. This doesn't mean Hank Pym is the villain (as many have speculated in the past), as he won't be in the suit. Pym is much more of a mentor to Scott Lang in this film."

Hank Pym will be portrayed by Michael Douglas, as opposed to being in a similar age to Scott Lang in the comics. The idea that Darren Cross would wear the suit is a new concept, or, as rumors go, it could be inaccuracy.

Are these Edgar Wright's concepts or are they revisions? We wouldn't know unless Wright would tell us. There would be some reactions for deviating from the canon, but the fanboys might be used to it already.
