Tony Stark doesn’t play well with others. What a load of crap, let’s look at who he’s had to ‘play’ with and decide:
Tony works well with the damn HULK. He prods him with a shock of electricity and they even work in a lab together. Bruce sees Tony as one of his closest friends and they might have disagreements but Tony still gets along with Bruce just fine.
Tony works well with Vision who is a supposed non-biases humanoid with an infinity gem, whether he created him or not he works well with him.
Tony works well with Rhodey, a colonel in the military and someone who tried to take his armor from him while he was dying and his friends of decades. They work just fine together.
Tony seems to work with T’Challa with no problem too. He never had any reason to call out T’Challa or give him any distrust like some he faced.
Peter respected the hell out of Tony and even when they just met Tony and Peter got along, even in the Homecoming trailer you see Peter looking up to Tony.
Tony does NOT work well with Thor, who grabbed him by the throat while he was out of his armor and the ‘team’ stood by and watched. I don’t care what you have to say about Tony Stark but the team stood by while a known Norse God grabbed a HUMAN by the THROAT while he had NO PROTECTION. Angry or not Thor shouldn’t have done that and the team is even worse for not even moving a muscle to do anything to stop him.
Tony does NOT work well with Natasha who has played double agent from the beginning and you never know who’s side she’s actually on other than her own. She started off writing a report on him that was written while he was DYING and she ENCOURAGED his behavior but then turned and wrote a report about how ‘Iron man was needed but not Tony Stark’. I’m sorry but isn’t she some kind of super spy? She knew Tony was dying, she knew he had no one to get him through this and when he asked her how she’d react she said she’d do whatever she wanted, but whenever she writes that report the circumstances are not mentioned AT ALL. She never makes a move to rectify that report and I guarantee you that plays a part in how people treat him on the ‘team’.
Tony does NOT work well with Wanda who played with his head, set off the Hulk, worked with Ultron, attacked him for the death of her parents (Which he knows nothing about), and then only turns to the Avengers because she found out Ultron intended to kill everyone and not just Tony Stark. Need I remind anyone that Wanda knew Stark would get hurt, was even counting on it, but afterwards he takes her into his home, gives her the latest tech and costume designs, gives her food and shelter, when she never apologized for what she did to him or any other Avenger. She played with their minds and never apologized yet Tony still took her in.
Tony does NOT work well with Steve Rogers who is a sanctimonious prick. Everyone says he’s this boy scout, I’m sorry, how the fuck is he a boy scout? No matter what his intentions were Steve Rogers went around and lied on government forms to get into the military. Yes, he had good intentions to do his part in the war, but he was still lying and breaking the law! The only reason that scientist found him was because Steve was lying again. Steve wasn’t chosen out of all these great soldiers, Steve was stumbled upon and the doctor liked him, believed he had heart. But then when Tony keeps something he lectures him on lying and keeping secrets, dude, you got your powers because you were lying! So to me, Steve Rogers is just a man and Civil War showed how flawed he was. Steve knew who had murdered Tony’s parents, or at the very least suspected, and he never said a word. Rogers knew that Tony’s parents were murdered instead of in this crash that you know Tony blamed his father for but he never said a thing.
In the few scenes we saw of them Tony and Clint bantered back and forth and seemed to get along just fine! But all of the sudden Clint comes out of retirement to fight a war when he had told the team that he was retired and the accords didn’t have any impact on him, yet here he is fighting them when he doesn’t know them. So I guess you can say that these two are up in the air.
And Falcon and Ant-Man? These two have not interacted with Tony enough to know him. Lang only knows him by name and hates him while Tony genuinely doesn’t know who he is. Falcon? Sam is blindly loyal to Steve and so him and Tony have a rocky relationship.
