Hey guys! How's everyone doing today? I don't know about you but I'm actually a bit surprised no one's written a fanfiction crossover like this before. Well, I mean there is one fanfic but it's in spanish and hasn't been updated in a few months so...yeah. Anyways, here's a fanfic where Bill Denborouh is Charles Xavier cause I love it when crossovers happen because of an actor's repertoire. It's always very interesting to read.

FYI, I'm mainly following the Singer verse of the X-Men films though let's be real here, the X-Men cinematic timeline is confusing as hell. Also, please be aware that I am definitely taking MANY liberties with dates and years and such considering It and X-Men occur in different decades.

Like always, I enjoy any comments, except for those that are just full of negativity and not constructive at all. Just give me something to work with instead of just "It's bad." I also appreciate any positive constructive criticism since I'm always looking to improve my writing and storytelling capabilities. Thanks for reading this story! Virtual hugs and cuddles to y'all.

Disclaimer: I do not own anything except any OC's that may come up, any world building that has not yet been officially stated by any medium, and any plot points/structures that have not been used in the books or movies.

Warning: No beta, we die like canon cause superhero timelines are the worst.

Prologue: To a New Beginning

XXXXXX

The summer after they defeated It was the best summer of Bill's life.

It was a summer of memories.

Of fun times and bad times. Of mourning and recovery.

It was a summer where the members of the Loser's Club were the closest they had ever been and will probably ever be because they defeated an evil clown hell bent on murdering kids all for the sake of feeding on their fear.

Richie somehow always managed to find ways to pull them all, especially Eddie, into his chaotic antics that landed them in the hot seat one too many times with the remnants of the Bowers Gang. He was still as much a trash mouth as ever but this time they were more appreciative of his humor than they'd been before.

Mike seemed to have some sort of heavy weight lift off of his shoulders. He seemed lighter like he'd finally received all the answers to his questions and was now content to just enjoy life as much as he could. Bill and the others would always go out of their way to stop by the Hanlon farm and help out with his chores so he'd be able to hang with them sooner rather than later.

Eddie moved past his germaphobia, though not enough that he stopped carrying a first aid kit and hand sanitizer everywhere he went. And constantly commenting on the health and safety of every location they entered, even the damn pharmacy. He still held the highest record among them for half the games in the arcade much to Richie's horror.

Ben emerged out of his shell more and more with each passing day. It was honestly heartwarming to see the shy new kid grow into a strong and kind hearted boy. He also somehow managed to find an underground space that was probably going to be some doomsday shelter and spent the better part of a month reinforcing the space and adding bits and pieces until it became the Losers' home away from home.

Stanley was still the same as ever, though he'd become more outspoken with his thoughts and opinions. Apparently something had happened on the day of his bar mitzvah that Eddie wasn't willing to elaborate on because it was "so epic" and "you had to have been there" to understand. He still loved bird watching as much as Richie loved to swear.

Beverly somehow became even more of a badass though it's most likely because she'd finally stood up to her father and got him both incapacited and sent to the slammer for what he'd done to her. However, her aunt had arrived to sort their affairs and take her away to Philadelphia after the summer. So the Losers made sure to make their borrowed time with her count.

Bill, himself, was finally on the road to recovery, having finally made his way towards the final stage of grief - acceptance. He rode Silver down the roads with a carefree attitude that he thought lost with Georgie. He finally got started on pursuing his passion of writing by writing anything and everything that came to mind in a notebook Richie got him as a "sorry your little brother was killed by a killer clown but at least we got the clown back for it" gift. Which, of course, was met with multiple slaps up the head and a crushing group hug that definitely did not end up in tears.

All in all, with the mystery of the missing children finally solved and It getting its just desserts, the oppressive atmosphere that used to hang like a weighted blanket around the town of Derry seemed to vanish overnight.

Unfortunately, despite this newfound lightness, his parents were still stuck in their own little world and as neglecting as always so not much changed in that department. But he could live with that, just as he'd lived with it ever since his little brother died. He had his friends now after all.

However, social services somehow caught wind of it and by the end of summer, Bill was swept up from his home in Derry and sent to live with relatives in New York. He packed up all his important belongings and was given enough time for a quick goodbye with the rest of the Losers and a promise to keep in touch.

Then he was off to Westchester to live with an aunt and uncle who had better things to do than look after a neglected and traumatized boy on the cusp of teenagehood. He will admit, his aunt and uncle certainly did a better job of looking after him than his own parents by making sure he was healthy, well dressed, and well educated. Though he could do without having to change his last name and suddenly having to use his full name again.

William Charles Xavier sounded really pretentious after all. Richie would've had a field day coming up with all sorts of nicknames for him while the others just nodded along sympathetically while secretly laughing at him like the traitors they were.

He'll always miss the days when his family was still made up of four people who loved each other very much instead of three strangers living together in a house.

That all changed though, when one day, only a month after he'd arrived, Bill got the sudden urge to head downstairs to the kitchen in the middle of the night.

As soon as he reached the bottom of the stairs, he knew something was up when he saw the kitchen lights were on. He hesitantly walked forward, body tense and ready for a fight, only to be met with the sight of his aunt, dressed in the semi-formal attire she'd only worn for that one family picture she'd insisted they take upon his arrival.

Bill blinks in confusion though he's still weary. He's about to say something when his aunt turns and sees him. She blinks in surprise, her expression shocked before quickly changing to neutral in the blink of an eye.

"What are you doing up so late?" she asks, "Do you want mummy to make you a hot chocolate?"

And immediately, Bill knew something was wrong. This was his aunt after all, she'd never call herself his mom. And, thankfully, this probably wasn't Pennywise the psycho clown because he'd have known exactly who his aunt was and would say as such.

Now, given that Bill didn't know who this person or entity impersonating his aunt was and he's not armed with any physical weapons, he defaulted to using the one thing he'd kept hidden his entire life for fear of further persecution.

His mind.

Well not his mind in that he's referring to his intelligence but rather the strange psychic abilities that had plagued him ever since he was five. He spent many years trying to keep that particular quirk under lock and key.

In fact, as much as he loathed to admit it, it was actually somewhat of a blessing that Georgie went missing because it allowed him to finally shove that strange part of himself firmly away, never to see the light of day. After all, he already got enough shit for being "Stuttering Bill" and that kid who lost his little brother. He didn't need to add freak to the list.

With his thoughts in hand, Bill threw them out like knives at the mind of the impersonator standing before him. Each raging question he tossed as he stepped forward had them shaking and shrinking under the weight of a voice suddenly appearing in their own head.

Finally, as he stands right in front of the impersonator, they physically shrink on themselves until all that was left standing in the place of his aunt was a little girl with dark red hair, bright yellow eyes, and blue skin covered in blue scales.

Bill gapes at her, eyes wide and jaw on the floor.

The girl shuffles nervously before he quickly shuts his trap and smiles reassuringly at her.

After a few moments pass, the girl quietly asks, "You're not scared?"

Bill chuckles because out of all the scary things that've happened to him, her appearance didn't even rank anywhere in his mind.

"N-no, I'm not. I-if I'm b-being honest, out of all the scary things I've seen, you don't even rank in the top ten or even the top one hundred," he says, stuttering a bit in the beginning before powering through with confidence. Then he quickly tacks on, "N-no of-f-fense."

The girl giggles at him, no offense taken at all. If anything, she's rather happy not to be treated like a monster as her thoughts so helpfully told him. Then her gnawing hunger broadcasts itself into his mind and he frowns.

"You're hungry right?" he asks. She nods hesitantly.

"Then you can take whatever food you'd like from this kitchen, hell you could take the whole damn kitchen and no one would ever notice," he firmly declares, waving his hand out towards the large pantry just off to the side. "You don't have to sneak in and steal."

The girl's eyes widen and she smiles. Then a sudden, impulsive thought clicks in his mind and now he's the one shuffling his foot nervously.

"I-in fact, y-you don't have to steal ever again. You can s-stay here if you want," he tentatively offers.

The girl's smile grows even wider and she hesitantly asks, "Can I? I don't...I don't want to be alone anymore."

Bill nods eagerly. "O-of course. I-I'll make sure you're n-n-never alone ever again."

Then he sticks his hand out for a shake and she shyly takes it.

"My n-name's W-william C-charles Xavier," he says, shaking her hand, "B-but you can call me B-bill."

"Raven," she says shyly, "Nice to meet you."

The two kids share a smile and suddenly, Bill doesn't feel so alone anymore.

Of course, it wasn't all sunshine and rainbows.

The two newfound siblings had a lot of obstacles to overcome.

Bill knew he'd failed Georgie and didn't want to fail Raven in the same way. So he always indulged her whims and spoiled her rotten in a way he was never able to with Georgie. He treated her like his second chance. However, that never stopped the guilt from overwhelming him.

Raven in turn found it difficult to shed the fear that a single wrong step would have him turn her out of the house and she'd be left all alone again. So she enjoyed the mothering attitude Bill had taken with her before it became too smothering and she confronted him about it.

When she found out about Georgie and all the shit that happened in Derry, she was understandably upset at the thought that Bill was treating her like some sort of pet project meant to soothe his guilt. The argument was the most explosive one to ever occur between them.

It took a week of Raven avoiding Bill so she could really think hard about what exactly she wanted before the two got together again to just talk.

And they definitely talked. They talked about anything and everything they could. They talked about their fears, their dreams, their worries, and their hopes. Bill talked about Georgie and Derry and the Losers but carefully omitted certain details because some things were just better forgotten. Raven talked about her past, how she was so fearful of her appearance and her parents hated her so much they'd tried to kill her at one point which led to her finally running away.

Eventually, they ran out of things to talk about. But with the air finally cleared, the siblings in all but blood finally felt settled into their relationship with one another. Of course, there were still ground rules that needed to be set.

Raven wanted her mind to remain her own private little place but was willing to allow Bill refugee for whenever he was overwhelmed by the world around him. In turn, Bill wanted Raven to always speak her mind with him and let him know if he was ever falling into bad habits that otherwise would've gone unnoticed until it was too late. Better communication was key to any relationship after all.

By the end of it all, their relationship was as strong as titanium. They communicated properly with one another, no secrets kept from then on. They protected each other from the cruelty of the world and helped the other overcome their own personal struggles. They were each other's shoulders to cry on and to lean against for support.

They also helped each other figure out ways to control their respective abilities, even managing to have a little fun with it along the way.

Bill would always encourage Raven to love herself, appearance be damned, while also allowing her to shift however she pleased with some rules put in place. The last thing he needed was for her to turn into Marilyn Monroe again and proceed to send the entirety of Westchester into another tizzy with conspiracy theories about dead celebrities not actually being dead.

Raven would always allow Bill to use her as an anchor while he was regaining the control he'd lost after many years of suppressing his abilities. Of course, she'd also always ask pretty please with a cherry on top for him to make the stuffy old principal of their school dance like Madonna whenever he was being particularly stuffy.

More importantly though, they accepted each other, flaws and all, and were better for it.

However, there was one thing that put a slight strain on their relationship.

It started gradually, like a snowball effect.

Just little memories disappearing, bit by bit, day by day.

But it kept growing and growing and growing until one day it grew so big that nothing could stop its path of destruction and Bill was left with a large gap of memories missing from his time in Derry.

The only remaining pieces left of the past he'd forgotten was a scar he couldn't remember how he'd gotten, life lessons he doesn't remember learning, and the psychic ability of telepathy that he had ever since he could remember.

Raven refused to allow this sudden memory loss affect the relationship between them and, in the case of her protectiveness over Bill, she ultimately decided that this is one case where ignorance is bliss. However, it did coax a newfound need to unlock the mysteries of the unknown within him.

That combined with his psychic abilities, led him to head on over to Oxford in the pursuit of a PhD in Genetics. He couldn't shake his love for writing though so he also minored in Literature, occasionally working on drafts of horror novels never meant to see the light of day if only to have a break from writing his three hundred and fifty page thesis on genetic mutations.

Along the way, he'd also gained an accent from the many speech therapy sessions he'd taken alongside his coursework. Raven loved to make fun of him for it because it made him sound all posh even though he could swear just as well as any sailor.

All in all, life was good. The past sixteen years have been good, even though he couldn't remember much of anything before that and Raven would always keep mum about it. However, he trusted her when she said it was better he never knew and that was enough.

Until the day he finally graduated with his thesis complete and PhD in hand and decided that tonight would be the night he allowed Raven to drag him to that dingy little pub on the outskirts of Oxford that she loved to frequent whenever she couldn't drag him away from his desk.

That night, he got mostly shit faced and ended meeting the woman who'd set him down on a path he'd never envisioned for himself even with his wildest imagination.

Ta-da! Sooo...how was it? My attempt to come up with a viable explanation for why Bill becomes Charles with as few plot holes cropping up as possible that is. I have such a headache now that I now actually have a newfound appreciation for writers in the superhero genre who have to deal with timeline and explanation headaches such as these. Anywho, I hope you enjoyed the start of my new fic and am excited for what's to come. Until next time!
