Disclaimer: I do not own Marvel Cinematic Universe, Charmed or anything else you may recognize

So I wanted to do a MCU/Charmed crossover, and I had one idea of the Charmed Ones' coming under Thunderbolt Ross' radar during Season 7 due to the Accords.

But Marcus S. Lazarus gave me another one which is a bit simpler so I'll do that first, then my original one too sometime.

Also, Paige and Henry are just really good friends here. I did like the ship in canon but it won't work here, so no Paige/Henry.

Updates will be a bit irregular since I have the outline but some middle portion here needs to be filled out with more substance, but it will be done, though I'll be giving priority to 'Angel and Devil in Law' and of course my Angel watch-it fic 'The path to redemption', but this story will also be carried on.

Hope all enjoy.

Chapter 1- Lost everything

Halliwell Manor

Laughter rang out in the manor as all were gathered for a little get-together. Piper was with Leo, the two of them smiling as they played with Wyatt and Chris at the table, along with Victor.

Phoebe and Coop were talking, while Billie was reading about a little spell in the corner.

Paige came downstairs after having made an addition to the Book of Shadows and passed her friend Henry as they shared a little smile.

They both sat back down as Piper told Paige. "So, Leo says he is going to run the magic school from now on."

"Good luck Leo, you're gonna need it, especially when you have to deal with rowdy kids", Paige said with a smile as Leo just chuckled.

"Yeah, well, I'm sure they'd be easier to manage than our kids", Leo shrugged as he rocked Wyatt and kissed his forehead, getting a happy squeal of 'daddy' from him.

"Don't be too sure", Paige added.

"Either way, I'm sure you'll get used to it after a bit, some of my parolees aren't the most pleasant people either but I had to get used to them in a bit and it worked like a charm once I worked it out", Henry shrugged.

"Were you punning when you said 'charm'?" Coop asked and more laughter followed.

"Didn't think of it actually", Henry revealed.

"How's the writing business, Phoebe?" Billie then asked as she finally walked to them and sat down as well.

"Writing a book about love, let's hope it helps other people", Phoebe said, sharing a smile and kiss with Coop as she finished her sentence.

"I'll buy it to help myself too", Victor added with a little chuckle of his own.

"You'll get one for free, don't worry dad", Phoebe assured him.

"It's nice just being together here with each other, with nothing to worry about", Leo commented, sharing a loving look with Piper, since he was right.

It was nice to just have a sweet and peaceful family gathering and have some fun while at it, since most of the time they gathered together, it was to battle the forces of evil, like when they had to take out Billie's sister Christy Jenkins.

Outside of the threats they faced, there were other ones too, like they'd seen in the news earlier that day that Tony Stark had gone missing after a fight with aliens in New York, but that was an Avengers problem and the group just hoped they'd handle it, in spite of their little split.

They had no idea how much worse it had gotten after that.

"Yeah, I love it that way too", Piper said, and in that moment an orange sparkly portal opened right there, and out stepped a bald and Asian man, his hands now behind his back as he looked around at all of them.

"Great, what do you want?" Phoebe asked with a groan.

"My name is Wong, a Master of the Mystic Arts", Wong introduced himself as the sisters and Leo exchanged looks.

"You're a Mystic?" Paige asked and got a nod. "We've met some of them at times, the head of your order is the Sorcerer Supreme, isn't he?"

"Yes."

"Why are you here?" Piper asked him.

"An alien warlord named Thanos has now attacked the Earth, and he wants all 6 Infinity Stones", Wong revealed, as Leo's eyes widened in horror.

"You know about these?" Piper asked.

"They control each aspect of this Universe- Space, Time, Mind, Reality, Power and Soul", Leo explained. "Someone with all 6 can do anything he wants, especially if that person is powerful enough to wield all 6 at the same time."

Leo turned to Wong. "So Thanos has them all now?"

"You know Thanos?" Paige asked Leo.

"The Elders know of him, he was never one they wanted to mess with, that was before he got any Infinity Stone", Leo told them, horrifying them even more at how powerful Thanos truly was. "And he wants to kill half of all life."

That just increased the terror everyone as Victor asked. "And why does he want that?"

"He believes resources are finite and we waste them, so half of all life dying would save the resources", Leo explained Thanos' philosophy.

"Couldn't he just double the resources?" Billie asked.

"I'm guessing he doesn't see it that way", Coop said with a sigh.

"Thanos does not have all 6 yet, only 4 last I heard, but you are going to be needed for the battle against him so that he can be defeated once and for all", Wong said. "Please, I need you to come with me."

They sighed, realizing their time for fun was at an end, and it was time to do their duty.

But then something happened that would haunt them all for the rest of their lives.

In Leo's very arms, Wyatt suddenly faded away, turning to dust.

"WYATT!"

Piper's and Leo's wails of grief both matched in volume as they stared at where Wyatt had been, but it wasn't just him.

Next moment, Chris in Piper's arms met the same fate as his older brother, and Piper was numb now, looking like she was about to break down.

Victor started. "What is-"

And then he turned to dust in that moment as well as Paige watched with wide eyes.

Leo realized what had happened. "Looks like Thanos-"

He never got to finish because he turned to dust as well, and the numb Piper fell to her knees, looking she was going to wail and cry any moment now.

Coop looked at Phoebe, then his ring, thinking of something, but he turned to dust as well in that moment, and his ring, which was on him, also turned to dust.

Before Phoebe could respond, she too got dusted.

Victor, his whole body shaking, put a hand on Piper's shoulder to comfort her but touched dust because Piper was now gone too.

"No", Paige whispered as Victor turned to her and also turned to dust in that moment, alongside Billie.

Wong looked around at the scene grimly before sharing the fate of all the dusted ones.

"Paige."

Paige turned to Henry whose arm was also dusting, and he looked up at her, eyes filled with horror and fear, before turning to dust himself.

A moment ago, she had been one of the happiest people alive, delighted to be with her family. And now, in one fell swoop, Paige had lost everything and everyone she cared about. They were all piles of dust around her, and she was alone.

She got up, staggering around, then fell to her knees and threw up, before looking up and listening to the sounds of people screaming outside, all having experienced something similar to her.

Lying on the ground, Paige covered her face and started sobbing at her irreparable loss.

Well, this is done finally, and was pretty darn hard to write since I had to dust the whole Halliwell clan other than Paige.

For Wong, there is no confirmation really whether he was dusted or not so for this fic I dusted him, though in one other I had him survive.

Since Charmed Ones are really important people in the magical community, I think Mystics would obviously know them and they could be one of the allies of the Mystics to warn about Thanos.

So I worked it in a way that they were enjoying their life and got dusted as soon as they were informed of Thanos.

Regarding Coop's ring, well, in the film we saw the stuff on people was dusted alongside them, like, if they were wearing it that is, so I took the ring out of the equation too, or they could just use the ring immediately.

Anyway, hope all enjoyed (or not) and see you all next time with another chapter.
