Tony Stark creates the armor completely on his own with some of Rhodey's help. He was planning on showing his dad, but they were both in a plane crash. The crash damaged Tony's heart while his dad was thought to be dead, he put on his armour to keep himself alive as he flies to Rhodey's place. When he first heard from Pepper that Obadiah Stane was being investigated, he uses the armor to spy on him, but when the armor detected a runaway train, he stopped it and saved thousands of lives. The public is now calling him "Iron Man". He then adopts the name and uses it to become a superhero.
As he builds more armors, he gave them to his two friends who took the names War Machine and Rescue.
- Superhuman Strength: Iron Man is capable of lifting massive weights. Stark once pushed himself to hold an entire crane and when Happy Hogan was in the armor, he could spin the container of a building water tower on his finger like it was a basketball.
- Enhanced Durability: The armor can easily resist bullets and low yield explosives. It can also withstand extreme temperatures like atmospheric re-entry and the cold of outer space.
- Flight: It can fly by the use of boot jets that can reach speeds higher than Mach 2.
- Repulsor Gauntlets: The repulsor gauntlets have many functions.
- Repulsors: Concussive force beams that are fired from the palms of his gauntlets.
- Secondary Proplusion: The gauntlets have a second propulsion system.
- Force Field: The gauntlets can generate a force shield around himself. Tony used this to save himself from the plane crash.
- Unibeam: A powerful energy beam that is fired from the power source on its chest, however it rapidly depletes the armor's power supply.
- Magnetic Manipulation: Iron Man can manipulate magnetic fields to move metal objects.
- Sensors: The armour can see the electromagnetic spectrum, has telescopic sensors and can detect sounds.
- Mini-Missiles: The Mark II has built-in high-explosive shoulder missiles.
- Life Support: The armour can sustain its wearer for an indefinite period of time.
- Can hack into computers to download information.
- Enables Stark to hack into radio frequencies.
- Has an autopilot to fly itself home while Tony is asleep.
- Allows the wearer to listen to news and police reports.
- It has a phone built into the helmet.
- Can use the power source as a flashlight.
- Analyze attackers, including detecting weaknesses in their bodies.
- Can translate languages.
- Scramble the suit's neural interface for a few moments to protect himself from mental attack.
- Lockdown Mode
The armor also has a remote command system to enable Rhodey to control it from a separate computer terminal if Tony can't, a security system to prevent people from opening it when Stark is unconscious, and a secondary transportation system enabling him to "skate" when the flight system is damaged.
In Ancient History 101 , Stark even creates a backpack that allows him to don the armour whenever and wherever he needs to, combined with anti-gravity tech so it doesn't weigh billions pounds (possibly based on how the comic version always carried his armour in his briefcase).
The first variation of the armour appears in Cold War, when he creates enhanced gauntlets on his armor to fight the Blizzard. After the fight, he talks about creating other armors, including arctic and space variants. New armors then appear in various episodes.
This armor first appeared in Whiplash to fight the eponymous villain.
