Unfortunately, even these Wakandan augmentations may not be enough, as the first Avengers: Infinity War trailer showed Tony getting a beatdown from Thanos.
In Iron Man 3, Tony Stark built the Mark XLII armor, which allowed him to remotely summon each individual piece of his armor to himself.
Could one of those (or both) happen in Avengers 4?
It was an impressive feat, but this manifesting armor is several leaps ahead of what we saw five years ago, and it couldn’t arrive at a more perfect time.
