Steve Rogers goes to Tony Stark's birthday party. Things progress from there, with a lot of flirtiness leading to propositions, and propositions leading to, well, what comes next, and Steve isn't even sure what he wants after that.

Or in which Tony knows what he wants, and Steve should probably get out of politics.

Summary: Mojo presents: Love Across the Multiverse! In tonight's episode, a battle-hardened supersoldier finds himself drawn to his handsome, genius teammate!

Pretty when you cry by MystikSpiral @ AO3 | ~2K | Oneshot | Steve/Tony | PWP
Summary: There were little things Steve took pleasure in. Reading books on anything that updated him history wise, documentaries on military tactics, getting Tony Stark to shut his damn mouth. The little things in life that made living so much more enjoyable-only if he had to put them in order, Tony choking on his own moans and gasps would hold a firm first place.

Summary: When Tony was sixteen, he got to meet his hero, Captain Steve Rogers, the Empire's not-literally-golden boy from the Continuity Wars. When he was twenty-seven, the aforementioned Captain turned Pirate picked him up at the outer edges of space. It would have been a good time to appreciate the abundant nudity that came from spending too much time with space colonists, but Tony had bigger worries than even Rogers' amazing hip-to-shoulder ratio. Something was sending the star-encircling computers that power the galaxy into a tailspin, and it was going to take a lot more than luck and skill to clean the mess up.

Crossfire by citsiurtlanu @ AO3 | ~27K | Oneshot | Animal Transformation

When Nick Fury asks him and Captain America to investigate a newly discovered world dubbed the Savage Land, Tony jumps at the chance, hoping to find something - anything - that'll fix him.

The two heroes team up to investigate Nazi activity at a mysterious castle. But Captain America is keeping secrets that could destroy their new partnership before it has a chance to begin.
Miles to Go by captainshellhead & vibraniumstark @ AO3 | ~4K | Oneshot
Summary: Tony came to the arctic circle to meet their guide, find an artifact, and sell more issues of Marvels. But when their guide doesn’t show and a blizzard forces him to seek unexpected shelter, Tony hadn’t been prepared for what-or in this case, who-he might find.
the best man in his world and a good enough man for any world by thyrza @ AO3 | ~25K | Oneshot | Tony/Steve | Implied/Referenced Mind Control; Minor Character Death; Period-Typical Homophobia

(Set in Iron Man: Armored Adventures 'verse but should be accessible as a high school AU to anyone who hasn't seen it)
Life Was Never Going to be Normal by Pookaseraph @ AO3 | ~31K | Oneshot | Iron Man: Armored Adventures
Summary: Tony Stark is on top of the world, he's saved the Earth, he's got his dad back, and he's ready to start his future. Now that the Starks have been reunited, it's time for Stark Industries and Stark Solutions first corporate collaboration: defrost Captain America.

Stand Back, I'm Going To Try Science by Good_News_Everyone @ AO3 | ~2K | Oneshot | Iron Man: Armored Adventures | Soulmates; Hearing Voices
Summary: Soulmates are a rare and cherished thing, a simple touch of hands bringing love that lasts forever. By all the rules of romance, they're meant to wait for each other and to trust in the vagaries of fate to bring them together.
Tony's never been good at waiting, and when he has science on his side, who needs fate?

When he resolves to confront them, can anyone stand between him and what seems to be the inevitable destruction of the Avengers? Or is it already too late?

NB: One of the first few Steve/Tony fics that I read (yes, I found them from the XMFC fandom), and the author's note at the end was probably what intrigued me about this pairing so much in the end. ^^"
And the Ashes Will Scatter by Sineala @ AO3 | ~5K | Oneshot | Marvel 616 & MCU | Hickman Avengers | Pre-Slash
Summary: After the mindwipe is discovered and the Time Gem sends the Avengers into the future, Tony returns alone to the present. But it's not his present that he returns to. He finds himself among the Guardians of the Galaxy once again -- but these Guardians have no idea who Tony is. Maybe that's exactly what he needs right now.
Breakfast is the Most Important Meal by CherryIce @ AO3 | ~11K | Oneshot | MCU & X-Men Comics
Summary: In which Steve is kind of a fossil but his squishy parts and feelings are still intact, Bruce hates blueberries, there's a mysterious banging coming from Tony's lab in the basement, and Emma Frost is not actually a stripper.
Catch Me Through the Looking-Glass by Ylixia @ AO3 | ~29K | Oneshot | Marvel 616 & MCU | Post-Civil War, Hickman Avengers | Steve/Tony | Established Relationship (MCU); Pre-Slash (616)

Have You Met Uncle Charles? by winterhill @ AO3 | ~3K | Oneshot | MCU & X-Men: First Class
Summary: AU crossover. Tony Stark has known Charles Xavier since Tony was eight and Xavier was his Uncle Charles. Now that Tony’s all grown up, Charles vets his dates. Well, most of them. Except for the ones where Charles brings someone who should really be in jail, not a fancy restaurant.
Slid off the back of this prompt in that it’s Charles who is Tony’s oldest friend, and Tony’s not much of a fan of Erik: By virtue of being Tony's oldest friends, Charles and Erik reserve the right to vet all his significant others. Through terrifying dinner parties. Even they can't find much wrong with Steve, though. And sort of end up asking why he's with Tony.

Imitations of Lives Lived by Kabal42 @ AO3 | ~4K | Oneshot | Marvel 616 & MCU
Summary: When Loki threatens their world, Tony Stark and Reed Richards find a way to communicate with alternate universes. In another world, another Steve Rogers answers and a very unlikely friendship is begun. One that leads to old, buried feelings awakening and new ones flaring.
Imperfect Mirrors by Sineala @ AO3 | ~9K | Oneshot | Marvel 616 & MCU | Post-Avengers: Age of Ultron; Post-New Avengers #3; Hickman Avengers | Dimension Travel; Fix-It; Minor Tony/Pepper (MCU)
Summary: Two months since Ultron. Two hours since the mindwipe. Things haven't been going well for Tony Stark lately, in two different universes. But they just might be able to help each other out.

Like Coming Home by missbecky @ AO3 | ~75K | Oneshot | Marvel 616 & MCU | Civil War & Secret Invasion | Graphic Depictions of Violence | Canon Divergence; Offscreen Major Character Death; Torture
Summary: After a tragic accident, Steve is given a chance to go back in time and deliver a warning to Tony in the hope of avoiding their fate. Something's gone wrong, though, because this is not his world he's ended up in. And that is definitely not his Tony who's planning to delete his own brain. Sometimes your second chance isn't at all what you were expecting.
Living In The Future by Closer @ AO3 | ~36K | Complete | Iron Man: Armored Adventures & Ultimate Spider-Man (Cartoon) | NATW
Summary: Eighteen-year-old Tony Stark is the boy genius who woke Captain America, and now he's stuck with him. That's not a bad thing, but between Steve's wide-eyed wonder at the new world and Tony's little fanboy crush, the awkwardness just keeps happening.

When they both get a second chance at a first try at fatherhood, it’s up to the two of them to learn from their own future's past.

Now that the Starks have been reunited, it's time for Stark Industries and Stark Solutions first corporate collaboration: defrost Captain America.

Stand Back, I'm Going To Try Science by Good_News_Everyone @ AO3 | ~2K | Oneshot | Iron Man: Armored Adventures | Soulmates; Hearing Voices
Summary: Soulmates are a rare and cherished thing, a simple touch of hands bringing love that lasts forever. By all the rules of romance, they're meant to wait for each other and to trust in the vagaries of fate to bring them together.
Tony's never been good at waiting, and when he has science on his side, who needs fate?

Summary: When Charles Xavier drops by to visit the Avengers, he's not expecting to see his early relationship with Erik written out between Captain America and Iron Man. And, somehow, it infuriates him, because they have all that he could never have, if only they could see it.
NB: One of the first few Steve/Tony fics that I read (yes, I found them from the XMFC fandom), and the author's note at the end was probably what intrigued me about this pairing so much in the end. ^^"
And the Ashes Will Scatter by Sineala @ AO3 | ~5K | Oneshot | Marvel 616 & MCU | Hickman Avengers | Pre-Slash
Summary: After the mindwipe is discovered and the Time Gem sends the Avengers into the future, Tony returns alone to the present. But it's not his present that he returns to. He finds himself among the Guardians of the Galaxy once again -- but these Guardians have no idea who Tony is. Maybe that's exactly what he needs right now.
Breakfast is the Most Important Meal by CherryIce @ AO3 | ~11K | Oneshot | MCU & X-Men Comics

Summary: Ian and Anthony's first holiday season on Earth 616 is a little rocky, but the Rogers boys and the Stark boys can survive anything if they stick together.
Have You Met Uncle Charles? by winterhill @ AO3 | ~3K | Oneshot | MCU & X-Men: First Class
Summary: AU crossover. Tony Stark has known Charles Xavier since Tony was eight and Xavier was his Uncle Charles. Now that Tony’s all grown up, Charles vets his dates. Well, most of them. Except for the ones where Charles brings someone who should really be in jail, not a fancy restaurant.
Slid off the back of this prompt in that it’s Charles who is Tony’s oldest friend, and Tony’s not much of a fan of Erik: By virtue of being Tony's oldest friends, Charles and Erik reserve the right to vet all his significant others. Through terrifying dinner parties. Even they can't find much wrong with Steve, though. And sort of end up asking why he's with Tony.

Summary: Tony switches places with Natasha, due to an experiment of Reed's gone awry (or so he says. Personally I suspect he was up to something).
Imitations of Lives Lived by Kabal42 @ AO3 | ~4K | Oneshot | Marvel 616 & MCU
Summary: When Loki threatens their world, Tony Stark and Reed Richards find a way to communicate with alternate universes. In another world, another Steve Rogers answers and a very unlikely friendship is begun. One that leads to old, buried feelings awakening and new ones flaring.
Imperfect Mirrors by Sineala @ AO3 | ~9K | Oneshot | Marvel 616 & MCU | Post-Avengers: Age of Ultron; Post-New Avengers #3; Hickman Avengers | Dimension Travel; Fix-It; Minor Tony/Pepper (MCU)
Summary: Two months since Ultron. Two hours since the mindwipe. Things haven't been going well for Tony Stark lately, in two different universes. But they just might be able to help each other out.

Like Coming Home by missbecky @ AO3 | ~75K | Oneshot | Marvel 616 & MCU | Civil War & Secret Invasion | Graphic Depictions of Violence | Canon Divergence; Offscreen Major Character Death; Torture
Summary: After a tragic accident, Steve is given a chance to go back in time and deliver a warning to Tony in the hope of avoiding their fate. Something's gone wrong, though, because this is not his world he's ended up in. And that is definitely not his Tony who's planning to delete his own brain. Sometimes your second chance isn't at all what you were expecting.
Living In The Future by Closer @ AO3 | ~36K | Complete | Iron Man: Armored Adventures & Ultimate Spider-Man (Cartoon) | NATW
Summary: Eighteen-year-old Tony Stark is the boy genius who woke Captain America, and now he's stuck with him. That's not a bad thing, but between Steve's wide-eyed wonder at the new world and Tony's little fanboy crush, the awkwardness just keeps happening.
