Clark and Steve would be great friends, with Clark being the troll he is and Steve being such a spiteful little shit. They would get along so well it would annoy the shit out of Bruce and Tony, who’d argue at the drop of a hat.
First they’d compare themselves to each other, then they’d try to compare themselves to either Clark or Steve like “Why’s he a better friend than me?” then they’d get into a fight on which of their teammates is the best.
Bruce: “Well, Clark wouldn’t let his views get in the way of the world and team, he’s accountable unlike your captain!”
Tony: “That’s because Steve has his own personality and opinions. And who are you to talk about accountable? The guy’s an alien!”
Bruce: “An alien who gave me kryptonite to keep him in check. He trusts me that much, can you say the same about Rogers?”
Tony: “Hey, that whole thing about Bucky was a gross misunderstanding!”
Bruce: “Your team tried to rip each other apart!”
Tony: “Your Superman ripped an entire city apart!”
Bruce: “He was doing what he thought was best and he fucked up. Which is something you do all the time.”
Tony: “He killed dozens of people!”
Bruce. “And your weapons killed thousands.”
Meanwhile, Steve is showing Clark how to use his shield.
Clark throws it a bit too hard and it flies into Stark Tower by accident and crashes through Tony and Bruce’s rich boy meltdown.
