Nerd hero and luckiest man on Earth Robert Downey, Jr., breathed life into the Marvel Cinematic Universe way back in 2008 with his inaugural performance as Tony Stark. In Iron Man, Tony created the Mark I suit under significant duress with few resources, which is why it looked like a walking trash compactor. Since then, though, all of Iron Man's suits have grown increasingly baller. But just how many suits does Iron Man have in the MCU?
Forty-six. Forty-six freaking suits! Now, only 30 of those awesome, mind-blowing suits of armor in Iron Man's arsenal have been fed to our glistening eyeballs over the course of RDJ's six appearances in the MCU, as most of the Iron Legion was destroyed in Iron Man 3 without real screen time. To see all of the Iron Man armors, you would normally throw on your pjs, sink into your couch, and watch roughly 15 hours of film footage. Since no one has that kind of time, the suits are all assembled here for your viewing and voting pleasure.
Official Armor Name: Iron Man Armor Mk XLVI
Special Properties: Mk XLVI sports yet another new design, once again making red the primary color, but debuting a new trapezoidal RT chest piece containing the Arc Reactor. It has a few new weapons: it can shoot electricity and a paralytic out of the hands. One of its coolest features is its collapsible helmet, which replaces the ho-hum garage-door face plate. In one of the most bad ass scenes of the MCU, Captain America destroys this suit by crushing the Arc Reactor in the climactic fight of Civil War. So, will Tony make a new suit for his next appearance? Yeah. Obviously. Stupid question, guys.

Hulkbuster (Mark XLIV)
Official Armor Name: Hulkbuster (or Veronica)
Special Properties: If you thought Hammerhead was going through a midlife crisis, prepare yourself for this 'roid monster. Mk XLIV was designed to take on the Hulk (as is rather self-explanatory). Hulkbuster has improved strength, a grappling hook, a jackhammer fist (which provides the hilarious "Go to sleep" scene), and a chemical spray. It is stored on a satellite and deployed when Tony activates the "Veronica" protocol, an homage to Archie Comics. (Bruce Banner dates a woman named Betty in the comics, the same name of a character in Archie Comics, which also touts a character named Veronica. It's a rather loose thread.)

Official Armor Name: Iron Man Armor Mk III
Special Properties: This is Tony's first weaponized suit outfitted with various sub-armor weapons, and affording the RT (Repulsor Technology) chest piece the unibeam capability—a powerful attack that transforms light into physical energy—with the same capability given to the flight stimulators on the palms of the suit. The Mk III sports the iconic red and gold color scheme and is upgraded to a titanium/gold alloy to fix the icing problem in the Mk II. Remember your elation when he first donned it? Oh, that was magical. The Mk III technically appeared in Iron Man 3 as it was destroyed in the Mandarin's attack, but we'll only count movies in which the suits were active.

Autonomous Prehensile Propulsion Suit (Mark XLII)
Official Armor Name: Autonomous Prehensile Propulsion Suit
Special Properties: Mk XLII is Tony's primary suit in Iron Man 3, so you'd think he could give it a name. Its color scheme is essentially a reverse of the original designs, with gold being the primary color and red the secondary. This suit has all the bells and whistles: a built-in self-repair system, all-around state-of-the-art weaponry upgrades, and a plasma-penetration unibeam that allows it to penetrate solid objects. It also utilizes similar technology to Bones, with the added feature of corresponding microchips implanted in Tony that allow him to control the suit through his nervous system and call it to him where it can equip piece-by-piece. This is how he escaped the Mandarin's compound in Iron Man 3.
