10 MCU Concept Art Designs Better Than What We Got

10. Many-Armed Ultron

Even with a huge army of robots on his side, Ultron could have used a few extra pairs of hands when squaring off against a team comprising Hulk, Thor, Iron Man, Captain America et al, and he was almost granted them in a very literal way.

Concept art Marvel shared after the second Avengers movie had hit showed a more menacing version of the villain sporting six arms. The extra limbs would definitely have boosted his screen presence.

Despite James Spader's admirable efforts on the vocal front, Ultron failed to live up to Loki's lofty standards set during Phase One, lacking the screen presence of Tom Hiddleston's mischievous Asgardian.

A few extra arms wouldn't have solved all of the bad guy's problems, or the movie's for that matter, but a six-armed robot was always going to be more memorable than a two-armed one.
