An idea I came up with about a week ago, wanted to at least start it so I could focus on other things. As the summary suggests, it's a Buffyverse/MCU crossover taking place at the end of Infinity War but it has a major twist to it.

Before we get started, I would just like to thank Aragorn II Elessar for helping me plan this. Thanks a lot buddy.

Wakanda

"I told you you'd die for that," Thor sneered at the Mad Titan Thanos, taking sadistic pleasure as he pushed Stormbreaker deeper into Thanos' chest causing Thanos to let out a pained cry.

Thanos' head slumped to the side, nearly resting on Thor's shoulder as Thor stared at him, thinking he had won. Thanos seemed to be mumbling something. For a moment, Thor thought Thanos was incoherent. Then, he realized Thanos was speaking to him.

"You should have…you should have…you should have gone for the head," Thanos said finally.

Thor's confusion lasted only a moment, as Thanos then raised his hand that wore the Infinity Gauntlet.

"NO!" Thor cried.

But it was too late and Thor could do nothing but watch as Thanos snapped his fingers. There was a bright flash of energy that blinded them. When it faded, Thanos' gauntlet was smoking from using the energy of the stones.

"What did you do?! WHAT DID YOU DO?!" Thor exclaimed in horror.

Thanos simply raised his hand, the Space Stone glowing blue before he vanished in a blue portal. Stormbreaker fell to the ground with a loud thud, the axe stained with the Titan's purple blood.

"Where'd he go?" Steve asked as he walked up beside Thor. "Thor, where'd he go?"

Thor didn't answer, seeming to be in shock.

"Steve," Steve turned around to see Bucky staring at him in horror. "Your arm."

Steve looked down, seeing his arm was beginning to disintegrate. Before he could react, Steve's entire body turned to dust, which then fell to the ground, leaving no trace of the hero once known as Captain America.

Bucky stared at the spot where Steve had been in horror before he looked over at Thor. Thor simply stared at him in guilt before he too turned to dust.

Okoye was on the ground, lying on her back as T'Challa approached her.

"Up General, up," he told her as he knelt down, grabbing her hand and pulling her into a sitting position. "This is no place to die."

As he started to pull her to her feet, T'Challa was horrified when Okoye suddenly turned to dust, the particles flying into the air as T'Challa watched, not quite processing what he was seeing.

"I am Groot," Groot said in horror as he watched Rocket turn to dust. "Groot."

Still trapped between the stones Thanos had created around her, Natasha was trying to get out when she turned to dust.

"Sam?" Rhodey called out, looking for his friend.

Nearby, Sam was on the ground. Sam pulled himself to his feet but, by that time, Rhodey had turned to dust as well.

"Rhodey? Rhodey?" Sam called out, seeing no sign of his friend.

Barton Farm

Same time

"Hey guys, enough practice!" Laura Barton called to her husband and daughter. "Soup's on!"

"We're coming Mom!" Lila called back as she yanked the arrow out of the target.

However, when she turned back to say something to her father, she froze. Her father was gone. Dimly, she noticed some dust particles where her father had been as she looked around.

"Dad? Dad where are you?" Lila called out and her mother and brothers looked around in confusion.

"Dad?"

"Daddy?" Cooper and Nate called out as the Barton children looked around for their father in confusion and worry.

"Clint?" Laura called out, her heart hammering in her chest as she got to her feet, running towards where she had seen her husband only moments earlier, looking around wildly and finding no sign of him. "CLINT!"

Los Angelus

Same time

In a bar, Angel, Wesley, Fred, Gunn, Lorne, Harmony and Spike all sat at a table. Everyone had drinks but none of them were laughing.

"She just…she never woke up?" Fred asked, her voice cracking with emotion.

"The Powers that Be gave Cordelia one more day. She chose to spend it helping us…helping me," Angel said quietly.

Wesley, Gunn, and Lorne all had unshed tears in their eyes as Fred put a hand to her mouth, muffling her sobs. Harmony had no such restraint, openly sobbing. Even Spike looked saddened by this turn of events.

Suddenly, the room was pierced with cries of shock and horror. They group jumped to their feet, whirling around to see several people were turning to dust as the other patrons stared in shock.

"What in the name of…" Lorne trialed off, at a loss for words.

Angel shared his feelings. Angel had seen a lot in the centuries he had been on this earth, but even everything he had seen hadn't prepared him for this. Was this the end, he wondered.

"Uh, guys?" Gunn said sounding panicked.

Angel turned towards him to see Gunn looking down at his hands, which were turning to dust. Gunn looked up at the helplessly before he turned into dust.

"Charles!" Fred wailed.

"What is happening?" Harmony asked freaked out.

Angel, on instinct, turned towards Wesley to ask him if he had any idea but the words died on his lips as he saw Wesley turn to dust as well.

"What is happening?" Harmony repeated.

"I wish I knew Harmonica," Lorne muttered.

Feeling something prickling at her hands, Harmony looked down, shocked and alarmed to see her hands beginning to turn to dust as well.

"Uh-oh," Harmony said before she turned to dust as well.

Angel looked down at his hands, waiting – or hoping, he wasn't sure exactly – to turn to dust as well. But nothing happened.

"What the bloody Hell is going on?" Spike muttered.

Angel didn't have an answer for Spike. All he knew was that Wes, Gunn and even Harmony were gone…just like Cordelia.

England

Same time

Willow looked around in horror, watching as literally half the army of Slayers they had collected over the last several months turned to dust. It had started with her ex, Kennedy, vanishing as she ranted about how Willow would only ever love Tara and she was tired of playing second fiddle to a dead girl. She'd turned to dust mid break up and the other Slayers had followed.

"Good Lord," Giles breathed as he took his glasses off, moving to clean them as he always did in stressful situations.

But he never got the chance. The glasses fell to the floor as Giles turned to dust. The Scoobies, including Faith, stared in horror at the spot where their mentor had once stood.

"What is happening B?" Faith asked.

"I don't know," Buffy said, looking down at her hands. "But I think you'll have to figure it out without me this time F."

Everyone turned to Buffy, seeing her hands starting to disintegrate before Buffy herself was dust, which fell to the ground in a pile.

"Buffy?! Buffy!" Dawn yelled, running to the dust pile that had once been her sister, frantically searching through it as though she'd find her sister inside it.

Willow and Faith were simply in shock. Willow instinctively looked towards Xander, who simply stared at her in shock before he turned to dust as well. Willow fell to her knees, tears running down her face, in shock at having lost both her best friends right in front of her.

Behind her, Dawn sobbed bitterly as Faith simply stood in shock, not sure what to do now.

San Francisco

Same time

Scott Lang had just returned from the Quantum Realm, collecting Quantum Energy to save Ava Starr from a painful death. He'd barely been back for more than a minute when he got a phone call. Pulling out his phone, he saw it was his ex-wife Maggie.

"Hey Maggie, everyone okay?" Scott asked upon answering.

"Scott," Maggie said, her voice a frantic sobbing sound that immediately had Scott on edge.

"Maggie, what's wrong? Is it Cassie?" Scott asked urgently.

"We were…we were just watching TV. Then…then she just turned to dust right in front of us. It's happening all over Scott, I ran out the door and saw two people turn to dust just her! Our little is gone!" Maggie got out as she sobbed.

Numbly, Scott dropped to his knees, the phone slipping from his hands and falling next to him. Dimly, he was aware of Hope by his side, saying something but he couldn't even begin to tell you what it was. Scott let out a wail of anger, grief and despair that seemed to echo throughout the city.

Titan

Same time

"Something's happening," Mantis said as everyone pulled themselves to their feet.

Barely had the words left her mouth when she disintegrated, turning to dust before her very eyes. Drax looked down as his arm began to turn to dust as well.

"Quill?" Drax called out before he had completely disintegrated.

Quill stared in shock and guilt at the spot where his teammates had vanished, realizing the consequences of his action.

"Stand steady Quill," Tony told him.

"Oh man," Quill muttered before he turned to dust as well.

"Mr. Stark," Peter called out as Tony fell to his knees, looking down as his hands turned to dust.

"Sorry Kid," Tony apologized before the rest of him turned to dust.

Peter stared in shock and horror at the spot where his mentor had vanished; not quite processing what he was seeing when Strange spoke up behind him.

"Peter," Peter looked over his shoulder at Strange. "There was no other way."

Strange then disintegrated as Peter fell to his knees, guilt and grief welling up in him. It was just like before. He hadn't been able to save Uncle Ben, now he wasn't able to stop Thanos. He'd failed, just like before.

"He did it," Nebula muttered beside him.

Peter didn't respond, numb to everything around him.

Wakanda

Same time

Wanda was openly sobbing as she held Vision's now grey body in her arms; the spot where Thanos had yanked the mind stone out visible for everyone to see.

A few feet away, Bucky stared at Vision's body as T'Challa looked down, devastated as M'Baku stood near him. Bruce, in Tony's damaged Hulkbuster armor, stood a few feet behind them as Groot sat on a log, looking like he was crying. Sam then arrived on the scene, staring at Vision's body and immediately noticing the absence of Steve, Natasha and Thor. Coupled with Rohdey's disappearance, it left no illusions in Sam's mind what was happening.

"Thanos really did it…he won," Sam muttered.

After a moment, Bucky fell to his knees, a devastated, guilty look on his face.

"Oh God."

The original Avengers getting help from characters from another fandom to undo the snap has been done to death by this point, I've already done it twice, so I thought let's give the New Avengers a chance at it, do something different.

Some things remained the same, Strange and most of the Guardians were snapped away and Bruce survived for plot purposes. But this story is going to be very different than any other post Infinity War story I've ever done.

Since the snap seems to target all sentient life such as animals, I see no reason why demons and vampires wouldn't be targeted as well.
