There is a pretty fair chance that War Machine’s injury in [Captain America: Civil War](tag:994409) is hinting to something bigger- the introduction of the 'Bleeding Edge Armor' in the MCU.
Before we approach further, one might ask…
What is the Bleeding Edge Armor?
The Bleeding Edge Armor was the first armor powered completely by repulsor technology. The armor is kept inside Tony’s body until mentally commanded to form any structure or shape upon Tony’s skin.
It consists of Nano-machines that can change their properties depending upon the structure commanded, and can transform into clothes and different armors. Due to the capability of transformation, it can repair itself and is almost invulnerable. The transformation depends entirely on Stark’s imagination such as a boxing glove and even a sword.
Apart from that, it also provides a 360-degree panoramic view to Tony around himself through installed cameras.
Now that we know what this armor’s capable of…
What Does It Have To Do With War Machine?
Y’see, in the comics when Rhodes was severely injured, he needed to be in life support and cybernetic implants were required to be placed in him. Stark used Bleeding Edge tech to build the Stanetech War Machine armor essential to save his friend’s limbs. The armor is made from a mixture of titanium and vibranium and can physically integrate mechanical constructs to repair and even upgrade itself such as fusing itself to a fighter jet or a tank.
This means that we might get to see some armor-bending action soon. Obviously enough, Stanetech Armor opens the window for the Bleeding Edge Armor too.
How Will All Of This Be Possible?
This is the part where things get interesting. There is already an Easter Egg hidden in the Avengers: Age Of Ultron that hints towards the BEA. When Hawkeye got hurt at the start of the movie, Dr. Helen Cho cured him with some kind of nano-technology. Bruce Banner then claimed that she was creating tissue.
This is when Stark walks in and Dr. Cho says:
This is the next thing Tony. Your clunky metal suits are going to be left in the dust.
To which he replies:
That is exactly the plan.
We kinda know that the ‘next thing’ will be the Bleeding Edge Armor, so it’s quite possible that it’s designed the same way Barton’s tissues are being made. I mean, this method did create a living body i.e. Vision. The armor metal may bind with Tony’s tissues the same way the Vibranium atoms bonded with Vision’s. It may be possible that the same regeneration cradle is used to merge the BEA with Tony Stark’s body.
