Hulkbuster

Never go for the big parts unless the plan is to make a slow, giant mech like the Hulkbuster in the Marvel Universe.

Concept Artist Phil Saunders released a series of concept art pieces from Avengers: Age of Ultron, featuring the Hulkbuster armor.

His fight with Tony in the Hulkbuster armor in Avengers: Age of Ultron proved that metal barriers and cages can stop him temporarily.

As a result, Meinerding went through several designs in which Mysterio wore a tough, bulky sci-fi uniform that's definitely reminiscent of the Hulkbuster.

Instead of merely being phased into a rock in the Hulkbuster armor, Bruce Banner could have also faded to dust from within the suit.

Then the green meanie spent the whole movie refusing the come out and play, while Bruce Banner had to learn to master Iron Man’s Hulkbuster armor just to be involved in the battle.

He even has a suit similar to Tony Stark’s Hulkbuster that was used in Totally Awesome Hulk event to fight the Green Goliath.
