As it so happened, Tony was working on his armor when the broadcast popped up; JARVIS had a very high success rate of picking out only the news he would be interested in, and then turning up the volume loud enough to get his interest. Not that it was really needed in this instance; his bland disinterest in the newest developments from LexCorp vanished at the words "armor" and "weaponry."
His head whipped around to watch just as Luthor extolled the virtues and gave a demonstration of very familiar armor. There wasn't much that really infuriated him, but Iron Man tech from someone else, mass produced and in public hands? That hit pretty much all the switches.
"Green and purple?" he had to demand even as he tossed down the wrench and headed upstairs to find Pepper and get on this. "He rips off my tech and he puts them in green and purple?" Somehow, that was almost worse than just patent infringement; red and gold wasn't stealthy, but it was stylish...or at least it damn well didn't clash.
