In every Marvel Cinematic Universe movie he appears in, Tony Stark debuts one or several new suits that he created in the gap between installments. One of the best parts of those movies is when the audience gets to see his newest design assemble over him for the first time.

While all of those scenes are cool for different reasons, some are much better executed and much more memorable than others. As the suits continued to evolve and improve over time, so did the suit-ups scenes.

The Cave Suit-Up

Yinsen helps Tony with his suit in Iron Man

The first version of the Iron Man armor was built out of the remains of Tony's Jericho rocket after Tony was captured by the Ten Rings and kept in a cave in Iron Man along with Dr. Ho Yinsen.

Since the armor is the original design and was made for functionality rather than style, it is much clunkier than the other versions. Also, since Tony didn't have access to a lab with better materials, he and Yinsen had to put the suit on manually piece-by-piece which only made the scene more iconic.

The Mark

The main suit-up scene of Iron Man comes right before Tony goes to Afghanistan after learning that more Stark weapons had been delivered to the Ten Rings.

Unlike the previous suit up scenes before it, this was the first time fans saw the process of the suit being placed on him fully automated, thanks to the rig Tony had built in his basement. It would also be the debut of the Mark III, the first combat-ready suit and the first to feature the character's classic red and gold colors.

Jingle Bells

At the start of Iron Man 3, fans saw Tony test out the Mark 42 while listening to "Jingle Bells". Thanks to the microchips he implanted in his arm, Tony can remotely call the pieces to him rather than needing a large rig to place the suit on him as he had in earlier movies. After he starts feeling confident in his ability to catch the individual pieces with his body, he instructs Jarvis to send all the components.

As the pace picks up, struggles to keep up with the rapidly flying pieces before finding his stride, even flipping and catching the faceplate of the suit before landing in an iconic superhero pose before a stray piece flies and him and knocks him off his feet and send the pieces of his body flying.

Battle of Greenwich Village

Endgame Iron Man Mark L Suit Up

The Mark L suit was first shown to us in Avengers: Infinity War when Tony, Doctor Strange, Wong, and Bruce Banner are confronted by Ebony Maw and Cull Obsidian as they arrive on Earth in search of the time stone. It is one of the most advanced suits he's created due to it being made up of nanotechnology which allows all the components to be held on his person.

Unlike the previous version of the suit, rather than assembling in pieces, it crawls onto his body from the arc reactor in his chest almost like liquid. While the simplicity of it almost takes away from the process, the fact that it is now so simple perfectly shows the evolution of Tony's tech.

The Briefcase Suit-Up

Robert Downey Jr. Iron Man Mark V Suit

In Iron Man 2, while Tony was participating in the Monaco Grand Prix after replacing the driver representing his company, the villain Whiplash appeared on the track and began slicing cars with his electricity-charged whips to draw Tony out. While Tony tries to avoid attacks from Whiplash, Happy drives himself and Pepper onto the track to save him, managing to pin Whiplash with his car.

Although Pepper and Happy insist that he get in the car, Tony instead tells Pepper to throw him the briefcase. Tony then opens the case, revealing that it's actually the Mark V armor, puts the suit on over his racing uniform, and proceeds to fight Whiplash. While it's hard to accept that Whiplash would wait for Tony to suit-up before getting free, the epic moment was worth the suspension of disbelief.

Stark Tower Freefall

Iron Man Mark 7 Suit Avengers Tower

In The Avengers, during the battle of New York, Tony goes to Stark tower to confront Loki. After the two exchange words and Loki's failed attempt to control Tony's mind thanks to the arc reactor in his chest, Loki angrily throws Stark through the Tower window to plummet to his death.

Fortunately, while he was inside, Tony put on the tracking bracelets and summoned the Mark VII which chased after him as he fell, armoring him and allowing him to fly off before he hit the ground.

The Mandarin Attack

Pepper Potts Iron Man 3 Mark 45

After foolishly telling the Mandarin the location of his home address, Tony's mansion in Malibu is attacked by the Mandarin's men. The scene features two cool suit-ups, the first being when Tony calls the armor and has it placed on Pepper to protect her after the initial missile is fired at the building and the two are sent flying backward.

The second suit-up comes when Tony strips the armor away from Pepper places it on himself while crawling along the floor and trying to avoid gunfire from the helicopter before falling into the water below after managing to take out some of the helicopters.

The Iron Legion Protocol

Legion of Suits in Iron Man 3

In the final act of Iron Man 3, Tony realizes that he and Rhodey aren't going to be enough to take down Killian and the group of Extremis soldiers so he has Jarvis activate something called the "House Party Protocol" which sends all of his Iron Man suits to his current location.

Rather than picking one suit and sticking with it for the rest of the fight, audiences see Stark constantly switch between them, alternating when one is damaged or destroyed. In the sequence, fans saw tony jump between the Mark XXXIII, Mark XVI, Mark XV, and the Mark XL suits nicknamed "Silver Centurion", "Nightclub", "Sneaky", and "Shotgun" respectively, each one with different special abilities.

The Hulkbuster

Hulkbuster Avengers Age Ultron Iron Man

In Avengers: Age of Ultron, after Bruce has his mind messed with by Wanda Maximoff and begins rampaging through Johannesburg, South Africa, Tony asks his AI to send him the Hulkbuster armor which was created by him and Banner to help take down the Hulk if necessary.

The suit then descended from an orbiting satellite nicknamed "Veronica" and starts assembling piece by piece over his Mark XLIII, turning it from a standard-sized suit to one standing at 11 feet high.

The Countdown

After learning the truth about the Mandarin and being captured by Killian, Stark attempts to call his armor to rescue him and begins counting down from 5 attempting to estimate the number of seconds before the pieces of his suit would arrive.

However, due to them being locked in a shed all the way in Tennessee, he constantly had to restart the countdown while insisting to the henchmen monitoring him that he would get free. Eventually, Harley Keener finally opened the doors, allowing the suit to escape just as Stark was in the middle of his 4th countdown, allowing him to obtain a gun and get the upper hand.

The Helicopter Suit-Up

Civil War Iron Man Mark 46 Button

In Captain America: Civil War, after realizing he was wrong and learning that Zemo was the real threat, Tony decides to join Captain America and Bucky Barnes in Siberia after discovering that's where they were going from Sam.

While leaving the RAFT prison in his helicopter, he presses a button that reclines his chair, places the Mark XLVI suit on him, and ejects him out of the aircraft so that he can fly on his own.

Stark Tower

Avengers Endgame Iron Man Mark LXXXV

In Avengers: Endgame, after time-traveling back in time to the Battle of New York, Tony sneaks into Stark tower through the same broken window Loki tossed him out of the first Avengers to spy on his past self and locate the two infinity stones. Tony then throws back himself out of the window and as he starts to fall, he dons his nanotech suit.

The scene is a direct parallel of the moment for the first movie, however, Stark's technology reacts much more quickly and he's able to save himself much quicker than he did before due to the improvements he made over the past 11 years.

Barn Door Protocol

Iron Man Barn Door Protocol Mark LXXXV

The most recent and likely final Iron Man suit-up scene comes at the start of the third act of Avengers: Endgame when Tony initiates the "Barn Door Protocol" before Hulk preforms the snap that would bring back the half of the population wiped out by Thanos in the last movie.

The Mark LXXXV armor crawls over Tony's body as he puts up the suit's energy shield to protect him and Clint Barton from the radioactive energy from the infinity stones.

The Test Flight

Iron Man Mark 2 Silver armor

Upon returning from the desert, Tony began created the Mark II, a sleeker chrome version of the one he built in the cave, to test and perfect the design and functionality.

Audiences only got to see bits and pieces of the suit being placed on Tony before the test flight that would lead to him discovering the icing problem that would help him in the final battle.
