Of course, that didn't mean that Tony could already fight Luke to a draw with this nano armor.
But Luke would have to display his real strength then, which wasn't what this test was about.
Tony had just wanted to throw a punch or two at Luke's face while the latter was still unfamiliar with the nano armor.
This was more a symbolic than practical act.
Luke was too lazy to quibble over that. In any case, Tony had nanotechnology, which was equivalent to him having nanotechnology.
Also, he had been in Wakanda for half a year, and could mix in some of the nanotech for the Black Panther suit.
Luke was happy to give the tycoon some preferential treatment for helping him refresh his abilities.
They stopped and returned to New York.
Tony had been busy finishing up on the nano armor, and had neglected his daughter, Morgan, for many days.
Pepper? She was already used to it.
