Movie Ending AU. Erik is merciless after Shaw is dead, taking out Moira and sending the missiles back at the ships that fired them. Charles refuses to join him and they go their separate ways, but he keeps getting in the way and Erik can't allow him to interfere with his plans. More importantly, he can't allow Charles to be hurt.

Erik keeps everything -- body, mind -- under wraps, leaving Charles no choice but to find other outlets for his desires. When those desires cut a little too close to home, though, everything comes out into the open.

Very quietly, Charles says, “Can you show me?”

“No.” Erik looks at him again, then, his expression as steely as Charles has ever seen it. His resolve is even stronger than his pain. “To show you this would be to make you share it, and I would never do that to you. Never.”

Erik's spent fifty years being a figurehead and he's ready to leave that behind. Luckily, so is Charles.

(aka Old Retired Dudes in Love)

Many of the pressures in Charles Xavier's life -- the sacrifices Erik and Charles make to be together -- the constant tension of being closeted -- Charles' relationship to the Church he once served as a priest -- his distance from his sister -- come to the forefront in 1967. Because in that year, for Charles, peace is no longer an option.

Erik knows that Charles is both the strongest and the weakest of them all. But the 'why' of the paradox somehow gets lost in translation.

Exploration of Charles' telepathy and his relationship with Erik. Much longer, more elaborate version of my short ficlet, 'And All of the Ghouls Come out to Play.'

Four years after the events of X-Men: First Class, Charles Xavier finds his X-Men on the losing side of their continuing battle with Erik’s Brotherhood. Azazel and Mystique have a child in secret and, unwilling to raise Kurt in the midst of Erik's war, they give him up to Charles to raise at his school for the gifted. He agrees to do so, on the condition that they visit their son regularly. This leads to tenuous contact between the Brotherhood and the X-Men outside of the battlefield for the first time in years, and both Xavier and Magneto realize that the lines dividing them are not as clear-cut as they previously thought.

Basically, Charles Xavier needs a date to his tenth high school reunion. Enter Erik Lehnsherr, Raven’s best friend, who happens to be a model and the new face of Calvin Klein.

They both know that neither would ever betray his ideals or force the other to do anything, but everytime they meet Charles secretly hopes Erik will kidnap him and Erik secretly hopes Charles will brainwash him into coming back home.

"Fairly everyday stuff. If it's too mundane, I'll completely understand if you're not interested."

If he wasn't interested? Erik gave him a blank look, and the words tumbled out of his mouth before he could stop himself: "you did see my record, right?"

"Oh yes, that," Xavier said vaguely. "I did. Metal, isn't it? I suppose that's why you were touching that gate. Can't imagine it myself, having my own abilities restrained."

Erik is the extremely talented, extremely scary chef at one of the top restaurants in New York, and Charles, the head waiter, is the only person with the balls to stand up to him. Their fights are the stuff of legend, and their argument over the Valentine's Day menu turns into one for the history books.

How exactly does a biological male have an identical twin sister, anyway? Hank has discovered that Charles is a transman, and used to use his telepathy to pass. Scott and Hank are furious that Charles never told them. Emma is underwhelmed. And Charles finds that he resents the notion that he did something wrong by using his telepathy to make people perceive him the way he feels he really is.

Prompt: Erik's nightmares are formidable, and Charles' proximity is the only apparent cure. Bonus for sleepy encounters.

In 1965, Erik Lehnsherr has infiltrated the NYPD for his own purposes -- but his powers make him a brilliant detective. Yet that's not why FBI agent Charles Xavier has sought him out. It's because the mysterious killer they're both trying to find is murdering people like them: other mutants.

Their search for a madman binds them together. Their inner demons may tear them apart. But the greatest danger comes when the killer they're looking for looks back ...

Erik Lehnsherr, world renowned wilderness survivalist, alongside his husband, Charles Xavier, survive the perils of the wild in order to bring you, Two Men, One Knife, an award winning reality survival series, available only on the Discovery Channel. Follow Erik and Charles as they travel to the world's most remote locations with only the most basic of supplies. Pitted against nature, this husband-husband team struggle to survive in some of the world's harshest climates while battling the planet's fiercest predators. Can they survive the Canadian North? Find out next season, on Two Men, One Knife.

When detective Charles Xavier finds himself hunting down a vendetta-driven serial killer, it doesn't take long for him to realize he's in over his head. It only takes a little longer for him to realize his killer is, too.

"I do believe the two of you were in the same year as boys, were you not?" Headmaster Shaw said. "Charles is the most competent deputy any headmaster could ask for, Erik, and he's been doing this for years…" He trailed off, as if finally noticing something odd in the way his Potions and Divination masters were staring at each other.

"Of course," Charles said quickly, his voice only a little hoarse, and stuck out his hand. "Welcome back to Hogwarts, Erik."

Father Charles knew.

If you went to him, whether in the confessional or for an informal chat over coffee, he somehow always knew what was troubling you, even before you said the words.

Charles had never before considered himself to be a fan of smoking.

Charles, a miner from a poor village in the countryside, saves the life of Erik Lehnsherr, scion of a successful business family and the richest man on Eisen. Charles is a telepath and somewhat anxious about it, while Erik abstains from relationships because the lights flicker and doors open and electronics vibrate when he gets too excited.

Also features a long-suffering sister, a foul-mouthed bodyguard, and a best friend with a heart that is definitely not gold.

In which there are princes, spaceships, long journeys, and old secrets uncovered. (An AU sci-fi fairytale)

Charles doesn't really care what his daemon chooses to be. Raven just wants it to happen. Erik has forgotten what it's like to have a soul. Alex is running for his life. And Sebastian Shaw knows, the moment his Pele settles, they're destined for great things.

Or, five different characters and how their daemon settled.

Set one year post movie, Charles overloads himself in Cerebro, and his mind goes walkabout; wherever he is (and he’s around), it’s not in his body. Erik temporarily takes over the school in his absence, and finds that there’s little time for resentment or hatred when he’s busy organizing assigned reading for English lit, keeping the youngest children out of trouble, and trying to talk Raven into wearing clothing for the boys’ sake. Somewhere in between taking responsibility for the students and dreaming Charles’ dreams every night, he manages to remember that he’s something rather more than a weapon. In other words: A Love Story between two Gentlemen, told in Prose, Epistles, and Nonsense Rhymes.

Sequel to An Ideal Grace, in which Charles and Erik navigate the complexities of their new relationship while battling external forces that seem determined to keep them apart. Fortunately they have one thing on their side: Love.

Erik is a fisherman who lives in a cottage by the sea; it's a quiet, secluded life, and he enjoys it that way. Charles has a bump on his head, with no memory of why he was dangling off the side of a dock, unconscious and nearly frozen to death.

Erik Lehnsherr is a visiting professor at Columbia University, as well as an acclaimed and award winning poet. Charles Xavier is a lead researcher with the Genetics Department who is well on his way to tenure. But what happens when Charles has to cancel a class because half his students abandon him in favour of a mysterious new English Lit professor? Naturally he ends up sitting in in the class, where Professor Lehnsherr mistakes him for a student. It's really too bad Erik has such a strict policy against dating students. It's also too bad Erik doesn't seem to know how to use Google.

Erik Lehnsherr has been charged with the brutal murder of Sebastian Shaw. His case isn't looking very good until he meets the right lawyer.

X-Men AU, Good Omens-style, with Charles as Aziraphale, Erik as Crowley, Jean as the Antichrist, and Raven as a badass motherfucker.

Erik gives up his powers to save a dying Charles.

‘Hey,’ the man purred, ‘you looking for a date?’

‘No,’ Charles said firmly, trying to keep his thoughts on his predicament. ‘I’m looking for my hotel. It’s called the Regent. Can you help me?’ He hadn’t met a whole lot of prostitutes before, but perhaps they knew about these things.

Apparently they did. They also charged unreasonable prices for directions.

Years later, Charles would remember that day. Sometimes he would wonder if he could have changed anything; other times he would despair over what he had since become. But he would always hold the image in his mind: Raven, laughing, and his thoughts flying alongside her on strong wings, silver-gold through the winter air. Once upon a time.

Charles is a bright young thing, and Erik the society columnist who catches his eye.

When Alex Summers broke out of supermax to rescue his stupid kid brother, he had no idea it was going to be so fucking complicated.

"My name is Nick Fury," he tells Raven. "And I'm here to talk to you about Cain Marko."

XMFC/Inception fusion AU. Erik is an extractor, Alex is his point man. They're assembling a team to go after the most dangerous mind in dreamsharing: Sebastian Shaw. But unless Alex and the team can keep him in check, Erik's desire for vengeance might just rip the whole job apart around them -- and then there's the shade that haunts his dreams...

The most powerful telepath on the planet could never be a pacifist.

"But you have to do it proper," Raven's blue fingers played with the corner of the book's pages. "Erik, he does, like, he does it like you're my lunch."

"I've only just started, just wait," Charles said cheerily. He turned back to the book and continued to read, "I'll eat half of you now and save half for later-"

"You're not doing the voices," Raven whined. "Erik does," and this time, out of her tiny mouth came a pitch-perfect mimicry of Erik droning in his native accent, just subtle enough for a four-year-old to still understand the words, "I'll eat half of you now."

He'll have to feed again and keep himself calm. Today he had been caught off guard, as embarrassing as it was for one of the oldest of the Lilim, but tomorrow, Charles would be prepared. Besides, it had been a very, very long time since he'd had to exert an effort to keep himself under control, and this could be decent practice.

After Magneto of an X2-ish future succeeds in the unthinkable, Charles sends his consciousness back to 1962 to guide Erik away from the path that will lead to the genocide of the human race forty years hence.

Charles knows that Erik has always loved him, and intends to use this knowledge + sex to seduce Erik away from his ideals in his youth.

There's no way this well-thought-out, sensible, debugged and 100% bulletproof plan can possibly go wrong.

It took twenty minutes to track Mystique down once he decided he needed her, the Brotherhood's Genosha base a sprawling complex that spanned half of the island. He found her in the planning and ops room, bent, half sprawled, across the briefing table.

"Professor Xavier is giving the keynote address at the Symposium this year," he said without preamble.

"I should hit on a man who comes in every morning at seven a.m. in a five thousand dollar suit, says the exact same eleven words - and I've memorised them, by the way: the usual please, yes that'll be all, thank you very much. Looks directly at the person manning the checkout when he does it and does not manage to smile a single time, even when it's Angel. Rushes out as soon as he gets his drink. That's the person you want me to ask out."

An alternate universe (they're all not mutants, just human) where Charles is a social worker who fosters troubled kids, and one day he meets Erik, an ex-druggie/ex-convict (or whatever else, I leave it to anon to figure out which demons are chasing him) who reluctantly agrees to stay for only a while, but ends up staying for good and helping Charles to raise the kids. Awkward parenting ensues.

Erik is an A-list action star who is notoriously difficult to work with, until the day he gets cast alongside Charles Xavier, rom-com darling who can charm the pants off movie audiences the world over and apparently even one Erik Lehnsherr. The paparazzi catch them out and about soon enough, and their real-life Hollywood movie romance becomes instant tabloid fodder.

Charles is basically the bride whisperer. It’s like he can read their minds.
