Marvel Comics announced The Ultron Agenda, a new comic that will hit shelves September 2019.
The teaser for the comic features a piece of promotional artwork by Mike Deodato Jr. The art shows Tony Stark/Iron Man facing off against Ultron. Above the title of the book is the phrase "Unite or Perish."
Additional information about the comic was not provided, and there's a lot about the book that's unclear at this time. No writer or regular artist has been announced, and it's unclear just how many issues the series will run. This may be related to Marvel's currently unspecified event for December, which the publisher teased in March.
Following the Rage of Ultron event, the titular artificial intelligence saw himself mentally and physically bonded with Hank Pym/Ant-Man, his creator. He then took on the name Ultron Pym/Pymtron, combining both of their strengths. That's almost certainly the version of the villain seen here. "Unite or Perish" might give some clue to the plot of Ultron Agenda, as the phrase invokes the Ultron Virus which integrates those who come into contact with it into the sinister A.I.'s hive mind.
Created by Roy Thomas and John Buscema, Ultron first appeared in 1968's Avengers #54. The powerful artificial intelligence was created by Hank Pym, and had his mind modelled on that of his maker. Ultron goes on to create Vision using Wonder Man's brain patterns. The villain is one of the fiercest villains in the comics. He appeared in 2015's Avengers: Age of Ultron, where he was voiced by James Spader.
