Marvel kicked off Comic-Con by releasing the first poster from Ant-Man, but they also added four more from their most anticipated film at the convention, Avengers: Age of Ultron.

Available at the Marvel booth during Comic-Con, the posters feature concept art of Scarlet Witch (Elizabeth Olsen), Iron Man (Robert Downey Jr.), Captain America (Chris Evans), and Black Widow (Scarlett Johansson).

Each poster has a character fighting off hordes of robots, led by the film's villain Ultron (voiced by James Spader), which seems to be the theme of the movie so far (at least through the images shown).

Scarlet Witch is one of two new heroes entering the superhero team, the other one being Quicksilver (Aaron Taylor-Johnson), and the first look at the heroine shows that she will be packing as much a punch as the rest of the Avengers.

Olsen has proved in her indie work so far that she is a talented actress and while she wasn't given much to do in her blockbuster debut in Godzilla, Joss Whedon should give her more than enough time to show off her skills in Age of Ultron.

The Scarlet Witch poster was designed by the Ant-Man poster designer Andy Park while the Iron Man one was designed by artist Ryan Meinerding.

Avengers: Age of Ultron is written and directed by Joss Whedon and stars Downey Jr., Evans, Chris Hemsworth, Johansson, Samuel L. Jackson, Don Cheadle, Colbie Smulders, Taylor-Johnson, and Olsen. It will be released in May 1, 2015.
