Avengers: Endgame didn’t focus on Iron Man’s armor in the slightest, despite it being the 85th version, while the Avengers: Infinity War version was the 50th. Iron Man tinkered around a lot with his suits, and the latest ones were part of the “Bleeding Edge” suite.
While we can never be certain if the Bleeding Edge armor in the MCU had the same capabilities as the comics iteration, we can still list all the things the suit could do. If a future film has the Bleeding Edge again, then these 10 secrets should come into play. You’ll be surprised just how much the armor could do in the comics, and the cost that came with using it.
10 It Was Part Of Tony's Body
You must be aware of the Extremis storyline due to Iron Man 3, and this was derived from the comics, where Tony Stark had great difficulties against his enemies, as the Extremis powers against him rendered his suit volatile to damage.
In order to fix this, Tony crafted the Bleeding Edge armor, which was one with his body. Don’t think it’s the same as you saw in Avengers: Infinity War; the suit was within Tony’s anatomy here. If one were to cut Tony up, you would be able to see the nanotechnology ingrained within him. So basically, Tony was the suit.
9 It Is Mentally Commanded
The films never really made this point clear, with the implication here being that Tony must either be commanding J.A.R.V.I.S. or F.R.I.D.A.Y. as to what he wanted the suit to do. In Iron Man 3, we saw him make gestures that indicated for the suit to function like he wanted.
The Bleeding Edge armor was the suit that was true to Tony, in that he didn’t need to command any system within it to do what he wanted; he only needed to think what the action was. This meant that the suit was fused with his thoughts, and its capabilities were his to command non-verbally.
8 It Can Be Made Into Any Shape
Speaking of creating things he could command, Tony could quite literally make whatever he wanted out of the suit. Those who’ve watched Big Hero 6 will know just how ridiculously imaginative lengths nanotechnology can go in fiction, and Tony could do even better feats than those.
He could change the shape of the suit however he wanted. If that meant making it humongous, then he could do that; if he wanted the suit to create nuke level damage, even that was achievable. Think of the armor acting as a Green Lantern ring if you want to understand the level of shapeshifting it was capable of.
7 The Suit Only Weighs 25 Pounds
More than a few people have wondered just how Iron Man can store all those gadgets and weapons in his armor without him being restrained by the weight. Well, he did have those limitations where his previous suits were considered, but the Bleeding Edge armor only added 25 pounds at the most!
That’s right, it was like having next to no weight for Iron Man, who was used to lifting tons. The nanotechnology enabled him to carry on without being constrained in mobility. Now that’s what we call real productiveness; he could create all kinds of weapons and never feel them on him.
6 The Arc Reactor Makes Tony Smarter
Unlike previous arc reactors, the Bleeding Edge one wasn’t there just to power the suit; it was meant to amplify Tony’s own abilities. We’ve already covered the part where Tony was basically the armor, and this was proven when he had heightened abilities even when the armor wasn’t activated.
While he didn’t have powers like super strength or others, he had heightened superhuman thinking capabilities (as if he wasn’t smart enough already), which allowed him to multitask at ridiculous lengths. He could also learn new tasks at alarmingly high rates; so much so that he could complete work people did in months within a couple of days.
5 A Secondary Musculature Acts As The Armor
Before you think “musculature” means some kind of gross exo-organic material that formed from his own body parts, that’s not what Tony made. The musculature was, in fact, a kind of armor that served as the barrier between Tony’s body and outside damage.
Previously, he’d had the armor material to protect him, but if he himself was the armor, then you can see how he’d be pretty unprotected. This is why the Bleeding Edge armor instantly created a kind of external musculature that would keep distance between Tony’s body and the outside world; an ingenious way of keeping him safe.
4 It Self-Repairs Without Limits
We did see the Mark 50 repair itself in Avengers: Infinity War, but there were definite limits to this, which were best seen in Tony’s battle on Titan against Thanos. The Mad Titan was able to hold off Tony’s attacks by busting the suit up, whose nanoparticles couldn’t fuse back together and were left on the ground.
The comics version is much more sturdy, as the nanofragments don’t just break apart, and instead repair themselves without any limits. While the repair itself isn’t instantaneous, it doesn’t take more than a few seconds at most for the nanoparticles to form again.
3 The Suit Has Cameras
You might wonder why Tony would need cameras in the armor if he has an A.I. available within it; that would be because even the A.I. isn’t fast enough to communicate to Iron Man about instant threats. The Bleeding Edge armor was installed with additional cameras all around the armor to give Tony a complete view of his surroundings.
He could have his sights dead straight on the sky, but still have a panoramic view of everything happening around. These were called “eyeballs”, since the cameras meant Tony was functionally all-seeing to every event happening within his vicinity.
2 Not Even Magneto Can Control It
The one villain fans agree will always have Iron Man’s number is Magneto, since the antagonist's powers are literally to destroy what Iron Man wears for his source of strength. However, Tony’s not a genius for nothing, and he even had the Bleeding Edge armor become immune to Magneto’s abilities.
This was done specifically for a battle against Magneto, where Tony sensed he would be at a disadvantage, and replaced the armor’s iron composites with nanotubes made out of carbon. The carbon particles enabled him to be free of the “metallic” quality of the armor, thereby not making him susceptible to Magneto’s powers.
1 It Can't Work Without A Host
For all the powers the Bleeding Edge armor had, it still came at a heavy cost of being part of Tony, who began to feel the toll of the armor’s capabilities on his body. While it was good for combat and world-saving, he couldn’t continue very long with it.
So, Tony had an operation to remove every trace of the nanoparticles of the Bleeding Edge from his body and was free from it. Unlike every other suit he had, the Bleeding Edge couldn’t just be put on again, and it was rendered useless once it was off. This confirmed that the armor just can’t function if it's not fused with another person.
