The first time I head someone say “Tony Stark created all his villains” I thought “Oh my god that’s brilliant! I love it!” because I honestly love the idea of a hero who started out as a villain and is now haunted by his past in the form of people he has wronged.
So I was actually a little disappointed when I watched the movies again because Tony had a lot less influence on his villains than I had been lead to believe. He has some, but a lot of it was trivial stuff we’re all guilty of.
Probably the closest thing to villains truly created by Tony because of malice. He was too stupid and self centered to see the pain his weapons caused these people and it took them kidnapping him to be shaken out of his entitled, drunken stupor. If not for them he would definitely have stayed a villain.
Tony was a victim of him rather than the other way around. Through it probably wasn’t intended when the first Iron Man movie came out, later movies have implied that Stane was a member of Hydra who helped arrange Tony’s parents murder, then made himself Tony’s new father figure and got to work grooming him, all so he could eventually become the owner of Stark Industries.
His beef wasn’t really with Tony but with Tony’s dad for screwing over Ivan’s dad. He basically just decided that the sons should continue their fathers’ battle and was ready to kill and maim hundreds of people to get to Tony.
Just a fellow arms dealer who fell in love with Tony. In an attempt to get ahead on the marked and impress Tony he broke Ivan out of prison and realized too late how mad Ivan was. Not evil so much as stupid and I have no idea how Tony could have stopped this other than fucking Justin so he wouldn’t be so desperate for his attention.
Created by Tony from the bottom up, and his version of a knee-jerk fear reaction. The moral of Age of Ultron: don’t let people with unchecked anxiety and PTSD create weaponized robots.
Tony didn’t meet him on the roof. Killian saw this as a good reason to turn into a murderous maniac instead of, you know, chill for a second.
Tony didn’t credit him for his invention and called it BARF, and when Quentin confronted him about it (implied flipped the fuck out) Tony fired him for being unstable, and was proven right when this prompted Quentin to hack a plan to murder millions and take his rage out on teenage Peter Parker. Notice how in the actual scene of Tony showing off BARF nobody laughs, but when Quentin remembers it there’s a laugh track. It’s heavily implied that he saw things as way worse than they actually were and overreacted. So yes, Tony should have credited him in the first place but a calm conversation would probably have solved it instead of, oh I don’t know, trying to kill half of Europe’s population.
So I suppose you could say Tony created his own villains, but it’s a lot less impressive than it sounds.
