Almost ever Marvel movie thus far has changed up the heroes' costume.  They've ranged from major changes like the Mach XVII armor from Iron Man 3 to subtle ones like Black Widow's catsuit from Iron Man 2 adding color to the belt buckle in The Avengers.  Avengers: Age of Ultron will continue this tradition with new additions to the outfits that will provide more of a team dynamic.  JoBlo reports that all new costumes will be adorned with the Avengers "A" logo, including "Hulk's 'extendable' pants (dark purple in color) that expand and shrink with his Hulk/Banner transitions."

Hit the jump for more details on the Avengers: Age of Ultron costumes, the Avengers Tower, the Quinjet, and the look of the film's big bad, Ultron (voiced by James Spader).  The film stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Scarlett Johansson, Jeremy Renner, Aaron Taylor-Johnson, Elizabeth Olsen, Paul Bettany, and Mark Ruffalo.  Avengers: Age of Ultron opens May 1, 2015.  [Minor spoilers ahead]

JoBlo breaks down what we'll be seeing when it comes to new outfits:

• Black Widow's costume update will feature not only the previously reported batons, but her suit is said to be more "TRON-style" in nature with blue lights and electricity around the suit. Her enemies will now receive electric shocks or a "widow's sting" when she hits them, giving her more of a "superhero" edge amongst her super-powered counterparts.

I hope there's a moment where Widow shows she can shock someone and then Thor calls down a gigantic bolt of lightning.

• Stark wears the Mark 43, a suit with less gold on it than IRON MAN 3, but still more than in THE AVENGERS. The chest core reactor will be back to the circular shape favored by director Joss Whedon. The Mark 44 is the Hulkbuster and will be his other suit in the film.

So does this mean the core reactor is back even though Tony threw it away at the end of Iron Man 3?  Perhaps it's not really all that necessary since Iron Man 3 showed that the core doesn't power the suit anymore; he can charge it with a car battery if need be.

• The Vision will be 100 percent Paul Bettany with his face and body all in metallic form, very shiny with gold, red, and green (as well as the yellow cape).

A few years back, that may have been too much for audiences, and they would consider it silly.  At this point, they've hopefully been acclimated to this kind of colorful outfit.

• Ultron will be more than just a helmet, with his full face being articulated, including the mouth. All movements from James Spader's face are used to bring more personality to the villain. The suit mock-up is reminiscent of the weapon that Agent Coulson used to shoot Loki in THE AVENGERS, which was made from the parts of the defeated Destroyer in THOR. The suit is said to have a "red firelight underneath, giving him a kind of 'Balrog' effect from LOTR."

JoBlo adds that he'll also have an army of drones (great for big battle scenes, I presume) and they'll look like Ultron "minus the glowing red 'energy' effect.

The Avengers will also be getting an upgrade in their digs and rides.  A sleeker Quinjet will also be bigger so it can hold all of the Avengers.  It will also be outfitted with more weapons.

Finally, the Avengers tower will be "'Stark style' in nature, meaning excessive and over-the-top."  Would we expect anything less?
