Marvel Comics has confirmed the presence of yet another hero in The Age of Ultron, Brian Michael Bendis and Bryan Hitch’s 10-issue crossover series that brings Ultron back to rumble with the Avengers.  Marvel’s third teaser for the Age of Ultron features Fenghua Zhong’s rendering of a short-haired She Hulk charging forward in a lunging attack with a ruined city in the background.  Also prominent in this new design is the now familiar Age of Ultron motto, "Submit or Perish."
The Age of Ultron #1 debuts in March.  The first two Age of Ultron Teasers featured Black Widow and Red Hulk (see "Marvel Unveils New 'Age of Ultron' Teasers").
