When Tony Stark returned to Earth, after deciding to take time to clear his mind, he started creating many new technologies for himself. One of these being this new armor, primarily used by Tony to test new technological developments.
This armor is powered by numerous Repulsor Tech cores, with "Repulsor Core One" being the one implanted in Tony Stark's chest. This armor's first version was composed of a liquid smart-metal which could be easily stored in a briefcase and be rapidly aligned to a subdermal guide to form the suit exoskeleton. However, this metal was not meant for battle, but rapid testing.
The newest model's composition allows the user of the suit to attach/de-attach different kind of modules depending on the situation in a similar (but more limited) way to the Iron Man Armor Model 13. The suit can also be retracted into a "backpack" to allow its user's arms and legs mobility, but easy to immediately reassemble.
Using technology given to him by Rocket Raccoon, Tony created the "Stark Omniversal Multitasking Software" to allow him to remotely control the armor on Earth via his Deep-Space Armor. This software was intended for emergencies when Stark was needed on Earth while he was in space with the Guardians of the Galaxy. The software approximate communication range is seven hundred light years.
The code "Hdgk(X)=H2k(X,Q)∩Hk,k(X)" is capable of overriding the armor in order to make it respond to whomever recites it.

- One major inconsistency in the way this armor has been depicted by different artists is the design of the helmet. Some artists like Greg Land, Mike Deodato Jr., Joe Bennett, and Luke Ross have drawn it with a design similar to the general Iron Man helmet outline used in the Marvel Cinematic Universe instead of the proper design created by Carlo Pagulayan. The biggest difference between the two helmet designs is that Pagulayan's faceplate lacks a mouth slit; the plate instead ends at the upper lip, and is complemented by a chin guard resting lower in the jaw.
- In Marvel Puzzle Quest, this armor is incorrectly listed as the Model 40. This is most likely due to the tentative numbering used by this article before its official numbering was provided by All-New, All-Different Marvel Universe #1.
