No further information is given of the image's origin.

Yellowjacket will be played by Corey Stoll. At San Diego ComicCon, Stoll said that the character is a protégé of Hank Pym's who comes into possession of a next-generation Ant-Man costume.

In the comics, Yellowjacket is a persona taken on by Pym following a psychotic breakdown. He is bolder and more confident than Pym, but is sociopathic and comes to represent Pym's dark side.

The film combines Yellowjacket with another Ant-Man villain, Darren Cross: a rival scientist and industrialist in the comics.
