9. Thorbuster Armor

Look, MCU Tony Stark is all about disaster preparedness.

He made Ultron to prep for a crisis scenario, he built the Hulkbuster before the Hulk went bad, he probably has an ice cannon hanging out somewhere in case he needs to turn Steve Rogers back into a Capsicle anytime soon. So why wouldn't he have a Thorbuster chilling in the back room somewhere?

The Thorbuster existed to, well, fight Thor. It is visually reminiscent of the Destroyer and can siphon power from Thor himself and turn it on his enemies. Now, the Marvel Cinematic Universe Thor is a pretty chill dude and probably won't go evil anytime soon, but having an armor that can siphon Thor's power is a pretty awesome idea.

Especially now that Thor has way more control over his lightning, he could just charge the hell out of Tony and then we'd have two founding Avengers hurling god lightning around and that sounds incredible.
