Here's a collection of killer concept art recently posted to the website of Marvel Studios' conceptual artist Rodney Fuentebella, showcasing his various alternative design takes and evolutions of Ultron and his many Minions and Sentries for Avengers: Age of Ultron. Fuentebella's polished visions have been a major influence on many Marvel projects, like The Avengers, Guardians of the Galaxy, Iron Man 3, Captain America: The First Avenger and Captain America: The Winter Soldier.
Take a look at these gorgeous images of Ultron Prime and his potent army of soaring A.I. drones and tell us if you'd make any alterations to the finished film versions.
