Headcannons For Each Avenger Being Jealous

Requested by Marckleorbl. Hope you like it!

Tony

-Tony Stark is the proudest man alive. He has zero shame. He knows who he is, what he likes, and he's not afraid to admit it.

-That includes his boyfriend, Y/N — his personal assistant, whom he very proudly seduced.

-There had been public rumors swirling for a while about the two of them being a couple, mostly because people had come to know Tony's habits. So, when paparazzi finally leaked photos confirming the relationship, no one was surprised. Still, Tony and Y/N had always known it was only a matter of time.

-While the whole world is well aware that Tony and Y/N are very much a thing, that doesn't stop people from shamelessly flirting with one of them — and no, it's not Tony.

-To Tony's surprise, Y/N developed a significant fanbase of his own. And with fandom comes thirst.

-It started with thirst tweets. Tony found them amusing at first. He even leaned into the jokes a bit, laughing them off — even though they made Y/N slightly embarrassed.

-But things took a turn when the flirting started to blend into real life. That's when Tony had a problem.

-It happened during a business trip. The couple were staying in a luxurious hotel and had stopped by the bar for a late-night drink. Tony excused himself to use the restroom, only to come back and find a journalist chatting up Y/N. The man had bought Y/N a beer and was leaning in way too closely — flashing every sleazy trick in the seduction handbook.

-"I see why Tony Stark hired you," the man purred. "We would've hired you instantly with your... assets."

-Y/N laughed it off politely, but it was obvious he was uncomfortable.

-Tony, however, felt something sharp and unmistakable — possession. In his mind, the only person allowed to look at Y/N like that... was him.

-Without hesitation, he walked straight up to the bar, wedged himself between Y/N and the journalist, and plastered on his most condescending smile.

-"Oh, hey," Tony said smoothly. "I'm Tony Stark. You know — Y/N's boyfriend?"

-The journalist blinked, but Tony didn't give him a chance to speak.

-"I see you're trying to butter up my boyfriend, and while I can appreciate dedication to a story," Tony said, voice like velvet over steel, "I'd recommend you quit while you're ahead. After all, it'd be such a shame if someone contacted your boss about your... unprofessional conduct. Wouldn't want that fancy job of yours to vanish overnight, now would we?"

-The journalist practically tripped over himself trying to leave.

-Y/N was thankful that Tony stepped in. It was a relief, really. Still, ever since that night, something in Tony shifted. He became more possessive — obsessive, even.

-If anyone so much as looked at Y/N with flirtation in their eyes, Tony had no shame in using his status, his wealth, and even his connections to shut it down — fast.

-Because in Tony Stark's world, Y/N wasn't just his assistant. He was his. Period.

Steve

-Steve Rogers is a man of tradition. Living in the past, he always saw a relationship one way. You had the man, who provides, protects, and is the man of the family. Then you had the wife, who takes care, supports, and stays by the husband's side no matter what.
