Promotional art for tie-in merchandise usually doesn’t reveal much about the movie in question. But a batch of new images online seem to give a lot of information regarding two mysterious characters of AVENGERS: AGE OF ULTRON (in theaters May 1, 2015), and the appearance of ANT-MAN‘s main villain (out July 17, 2015).

Take a look below if you want to learn more about Ultron, The Vision, and the arachnid Yellowjacket.

Ultron’s origins (spoiler alert!):

“First discovered as a simple computer program hidden among the ruins of the Chitauri invasion of New York, the being known as Ultron soon completed its development into a sophisticated artificial intelligence after some experimentation by Tony Stark. Ultron’s first shocking ultimatum upon gaining consciousness was to declare the human race its enemy. Setting out to exterminate all life on the planet, the unstable and emotional Ultron seeks to upgrade its mechanical body to an ultimate, unstoppable form. With an army of robotic drones and the ability to enter and corrupt any computer network, Ultron will stop at nothing to see humanity wiped out.”

The Vision’s origins (spoiler alert!):

“Programmed by the combined geniuses of Tony Stark & Bruce Banner and imparted with the ability to fly, project intense energy beams and change the density of his form, the Vision has proved himself a worthy hero, aiding the Avengers in their struggle against the evil A.I. Ultron.”
