I am quite pleased at the increased level of interest in this tale. Thanks for all the reviews. Sorry for those that were upset that I'm so casual with Dawn's history. I'm like that in all my crosovers stories. I don't think it's a big deal. Knowing about her origins in no way hurts her or endangers her. She has no mystical power. Not on the show anyway. The next few chapters will focus on Thor and the Asgards. This will mean some of the Avengers will be left behind. This chapter should mostly answer some of your questions.

This story will probably not include Thor 2, but I could change my mind.

Disclaimer: I don't own the characters—just this story!

Chapter 12: Kidnapped

******Same Scoobie Time, Same Scoobie Place*******

Buffy could not believe what had just happened. She looked at Clint and Steve, who looked as stunned as she. "What the hell just happened? Why in the world would Thor kidnap my sister like that?" she demanded, her eyes flashing fire.

Kennedy moved to stand next to Buffy, her eyes equally deadly. "What game are you guys playing?" Kennedy asked Natasha.

Natasha exchanged confused looks with her friends and pulled out her phone to call Fury. "We have a situation," she said into it.

"We had no idea Thor was going to do that!" Clint assured her.

Buffy pulled out her phone. "Willow, I need you now! I'm at SHIELD. Thor took Dawn," she said.

"What do you mean?" Willow asked, distracted as Tony was explaining something to her.

"He opened up a portal and took her—I assume to Asgard," Buffy said, trying not to panic.

"We'll be there soon," Willow said, hanging up.

A minute later, Nick Fury, trailed by Agent Hill, came out of the building. He was a bit startled to see the pure rage coming from both slayers' eyes. "Ladies, how can we help?" he asked in a calm tone.

Buffy stepped up to him, glad to have someone to focus her anger on. "You can help by telling me what Thor could possibly want with my sister!" she bit out the words.

Nick looked at Clint, Steve, and Natasha for help. "What do you know?" he asked them.

Before they could answer, there was a flash of energy. Willow stood there with Xander and Tony, who had insisted on coming with them. Tony grinned hugely. "Did you get that JARVIS?" he asked. He was determined to understand the science behind Willow's magic. "I did, sir. The energy wave is not something that has ever been measured before." When Xander glared at him for his distraction, he whispered, "We'll talk later."

"What happened?" Willow asked.

"Why don't we go up to my office and calmly sort through this?" Nick said in a reasonable tone.

"If something happens to Dawn, there is no place on earth that will protect any of you," Kennedy said coldly, sweeping her gaze to all of them. Kennedy loved Dawn like a sister. Many of the slayers did. If SHIELD was behind this, they would find their new allies quickly turned to enemies.

"And you are?" Tony asked, stepping forward.

"That's Kennedy, our third ranked slayer. Willow's ex," Xander supplied.

Willow reached out and took Kennedy's hand, grateful for her support. The two women had a deep affection for one another. Their break up hadn't been without heartbreak, but the love between them was abiding.

"Introductions can happen later!" Buffy said angrily. "I want to know what is going on!"

"As do all of us. I assure you," Nick said. "Follow me." Without waiting for an agreement, he turned and marched toward his building. When he heard footsteps behind him, he allowed himself a moment of satisfaction. He had no idea what would possess the Asgardian to take Buffy's sister. He knew convincing her of that fact would not be easy. His newly formed alliance would go up in flames if he couldn't convince them of that fact. He flinched to think of the damage that would occur if he could not reassure the deadly trio.

Xander looked more than a little upset. "Buffy, I don't understand. Why would Thor take off with Dawn? That makes no sense!" he exclaimed, his eyes dark with confusion and fear.

"He didn't bother explaining. He said he was sorry. Then he opened a portal and disappeared with her," Buffy said.

"Well, that's a good sign. If he said he was sorry," Willow said weakly.

"I didn't realize what he intended until it was too late," Buffy said, her grim expression didn't alter.

They filed into Fury's office. He walked around to his desk. "So what exactly occurred?" he asked.

"Buffy and I were standing outside waiting for Steve, Natasha, Dawn, and Kennedy. We had dinner plans. Thor came up to us," Clint explained.

"What was his mood?" Nick asked, trying to make sense of his behavior.

"He was fine. He told us that Jane had forgiven him, but she was back in England. He seemed happy. He said that needed to head home. Then when Buffy's sister and everyone approached, he was transfixed," Clint said.

"He focused on Dawn exclusively," Buffy cut in. "He said the word Atali. He looked upset."

"Actually, it was more like awe," Natasha said. "We saw his face. You and Clint were behind him."

"He first asked who Dawn was. Buffy said she was his sister and asked if he wanted to join us for dinner," Clint explained.

"I think he looked more than a little upset at Dawn's appearance," Steve offered, speaking for the first time. He was perplexed by Thor's odd behavior. However, he knew Thor to be honorable, so he wasn't as concerned for the young woman's safety as her sister and friends were.

"He marched over to Dawn and put his hand on her face, so he could examine her more closely. It was creepy, but not really threatening. So I just stood there and let him," Buffy said, disgusted at herself. "He kept saying Atali. I don't know what that means."

"JARVIS says it's an Asgardian name for a female," Tony offered.

"Did Thor say anything else?" Nick asked.

"He asked me if Dawn was my natural sister. If she was born from my mother," Buffy answered. "When I told him not exactly, that she was created out of my blood, and that she was a mystical key some monks had given to me to protect, he grabbed her hand. He said he was sorry and took off with her."

"Actually, he told Dawn not to be afraid before he left," Clint added.

"So he didn't appear angry?" Nick asked.

"No. In fact, he seemed spellbound, if you can imagine," Natasha said.

"I know Thor. He would not harm an innocent," Steve said. "You should not be so worried. She will be okay."

Buffy gave him an angry glare. "Some demi-god that I barely know disappeared with my sister, taking her to another freaking planet in another galaxy, and you want me not to worry? Are you even human?" she demanded, no longer finding his perfect features and placating tone as appealing.

Steve frowned at her hostility. "I'm sorry. I meant no offense. I just know Thor. He would never hurt her," he said.

"I'm not sure how things were back in the 40's or 50's, but now a days we consider kidnapping harmful!" Buffy explained, finding herself more and more irritated with her crush.

Xander was trying not to panic. Buffy and Willow were unaware of the fact that he and Dawn had fallen in love and had been together the past six months. Xander was still a bit weirded out that the young girl who used to crush after him had grown up into such a lovely woman. He wasn't sure if Buffy and Willow would be upset or not, so he'd been waiting for the right time to tell them. Now he was regretting his cowardice. He stepped to Buffy. "Thor's a good guy. We have to trust that she is in no immediate danger. He has no reason to hurt her," Xander said.

"That we know of! We have no idea about Dawn's existence before she was fashioned into my sister!" Buffy reminded him. "She is ancient. Isn't Thor immortal? How old is he? He must know something about the key that we don't know! Glory wanted to use her to open a hell dimension! Who knows how these Asgards will try and use her?" Fear for her sister was building.

"We've only met Thor and his brother Loki," Tony said. "We know that Thor is honorable. However, Loki made it clear that humans were like bugs beneath his Asgardian feet."

"We must get to Asgard. Have any of you been there?" Buffy asked the group.

They all shook their head. "Who would know the most about their realm?" Willow asked.

"Jane Foster," Natasha said.

"And Dr. Erik Selvig," Clint said. "Erik was the one Loki first possessed to harness the power of the Tesseract to open the portal that brought in the Chitauri."

"Dr. Selvig has kind of gone off the rails since the invasion," Natasha said.

"What exactly are you thinking? We do not possess any type of technology that would allow us to travel to another universe," Nick said.

"If portals allow Thor to move from here to there, then I will figure out how to do the same," Willow said determinedly.

"You can do that?" Tony asked in surprise.

"I guess we'll find out," she replied.

"So give me the address of Jane Foster. Willow and I will speak with her," Buffy said.

"I'll have my jet ready," Tony said. "She's in London."

"I'm not waiting ten hours!" Buffy said.

"We could video conference with her," Willow suggested.

Nick nodded and looked at Agent Hill, who immediately left to set it up. "We will talk to Foster. I know that Thor has vowed to safeguard humanity. I cannot imagine he means your sister any harm," Nick said.

"Well, my sister isn't exactly human—not completely!" Buffy said hotly. "The last time someone took her, I had to die to save her!"

Nick didn't know what to say to that. Neither did anyone else.

"We need to call Giles," Xander said, ending the awkward moment.

"Let me take you to a conference room," Clint suggested. He led them to the room across the hall. After opening the door, he stood back and let them file in. He stopped Buffy by taking her hand. "Don't worry. She'll be okay," he told her, squeezing her hand. Buffy gave him in grateful look before going into the room to call Giles.

*****Asgard*****

Dawn was equally freaked and confused. Suddenly, she was on a golden platform of some kind. Thor released her.

"You didn't tell me you were bringing a guest," Heimdall said in disapproval.

"I am sorry. There was no time. Father must see her," Thor said.

Heimdall stepped closer to Dawn, who instinctively stepped back at the strange man's appearance. His eyes were decidedly not human. She fixed Thor with a glare. "What's going on? Why did you bring me here?" she demanded. "My sister is going to kill you!"

Heimdall looked amused. "You always know how to make friends, your highness," he said.

"I'm not easy to kill," Thor replied. He turned and looked down at her, still unable to believe what he suspected. His hand went again to her chin.

Dawn smack it away. "Stop touching me, you big goon! What is wrong with you?"

"I am sorry," Thor said, looking sincere. "I had to bring you to Father. Only he can decipher the truth of the matter."

"What truth?" Dawn asked.

"That you belong here with us," Thor said.

"You are thinking the Serpent?" Heimdall wondered.

"The resemblance to Atali is too strong," Thor said.

"I'm not a snake!" Dawn said hotly, images of the giant snake Glory had sent after her in her mind.

"Come," Thor ordered as he reached for her hand and let her out of the room.

Dawn gasped in amazement at the bridge they stepped on. It was something out of a dream or fairy tale. Magic and science obviously in perfect symmetry. She gaped as she let Thor lead her across the bridge.

Thor took her directly to the throne room. He knew taking the girl without permission was not the best course of action. However, their family had mourned too long to be kept waiting another moment to discover the truth.

"Father, forgive me for intruding. I have discovered someone that I had to bring to you immediately," Thor said. He pulled Dawn forward.

When Odin's eyes zeroed in on Dawn's, he got to his feet. "Who is this?" he asked, urgency in his tone.

"She is two things. Currently, she is Dawn Summers, the sister of Buffy Summers, who is a fierce warrior and protector of earth. However, her sister tells me that she was once a mystical key. She was fashioned into this form," Thor explained.

"Can it be?" Odin said in an agonized tone. He stepped down until he was directly in front of Dawn.

Dawn was trying not to panic at the ancient, imposing figure now gazing at her in wonder. "Uh, hi," she said, offering a weak smile.

"Child, I mean you no harm," the man said. "I'm Odin, ruler of the nine realms, father of Thor, husband of Frigga."

"It's nice to meet you," Dawn said.

Odin held out his hand. "May I?" he asked.

Dawn glanced nervously at Thor, who gave her an encouraging smile. She knew that the Asgards were not considered evil. She had to trust that he meant her no harm. His expression was too kind to invoke real fear. She placed her hand into his.

Thor watched as his father's magic engulfed them both into a white ball of energy. His mother looked down in concern. Thor gave her a reassuring smile.

After a moment, Odin released her hand. He gazed at Dawn in disbelief. "It is she. Our daughter has returned to us!" he exclaimed. He looked up at his wife, his eyes full of tears.

"Uh, excuse me?" Dawn squeaked.

"My oldest brother Cul long ago was lost to us as he fed on fear and hate, becoming the serpent. Yet one thing he managed to do was produce a most perfect child. Atali. She was ten when I married Frigga and imprisoned Cul in his underwater prison after he slayed her mother in his madness and rage. She was raised as a princess of Asgard, our adopted daughter, my niece. Sister of Thor and Loki," Odin explained.

"She is Atali?" Thor asked.

"There is no doubt," Odin said with a smile.

Frigga came down to stand at his side, gazing in wonder at Dawn, who wished desperately Buffy was here.

Thor smiled hugely. "My sister lives!" he exclaimed joyfully. Then he embraced her.

"No friggin' way!" she exclaimed.

*****Chapter End******

So for my comic book readers, I pulled Atali from a random list of Asgard names. I did so before realizing she was an actual character in Marvel universe. In my story, it's just a name for an Asgardian female. Cul is a real character, though, a forgotten and banished brother of Odin. The rest, of course, I made up. Dawn's creation is so cloaked in mystery and mysticism that it was too easy to put her in the Thor family tree. I hope you like this twist. More details will unfold in the next chapter.
