This is the answer to who will recruit Buffy to be their Champion after she is not longer the Slayer. This comes up at the end of "Supreme" so you might want to take a look there if you haven't read it yet.
As before, I don't own these characters or universes (Buffy, Marvel and DC).
“Why are you here?” Buffy asked Willow as they stepped out of the school and into the sunshine.
Willow looked at her, blinked, glanced back at the school, looked back at Buffy, then finally replied, “Uh, because since Giles left they won’t let us hang out in the library until midnight?”
Annoyance at having her former Watcher gone warred for a moment with the memory of the day three weeks ago when Giles had, in the middle of the cafeteria, resigned with a recitation of his letter.
The list of insults he’d then heaped on Snyder had been as impressive as the number of languages he’d used.
“I meant, why are you still going to school.” Buffy waved a hand as she went on, “I mean, it’s not that I don’t appreciate the company, I do. But Xander didn’t come back, Giles is gone, and Cordelia hasn’t exactly made you feel at home.”
“Actually,” the once-again-redhead admitted, “Cordelia’s appraisal of my outfits kinda feels like home.”
“Yeah.” The two walked along with matching smiles until they were off of school property. Then, Willow said, “I-I know it seems strange, with Xander not coming back and all, but I always liked school.”
“Well, I guess someone has to.”
“Hey,” Willow reminded her, “you-you know your grades have gone up a lot in the past few weeks.”
“Without the slayage there’s plenty of time for me to be homework gal,” Buffy explained. Frowning, she looked down. “I just wish I could keep myself from looking at the paper every morning and seeing people I might have saved.”
“Too much knowing what’s out there?”
“And not enough knowing what to do about it.” Buffy sighed. “I mean, you and Xander were out there fighting the forces of darkness with me, but there was always someone –“
“You,” Willow supplied.
“Yeah, me. Anyway, there was someone there to back you up who had slayer powers.” Holding up her hand, she looked at it as she said, “I guess I’m just scared about what could happen.”
“Hey, maybe you could patrol with Angel?”
There was a sharp shake of her head before Buffy said, “No, I tried it. He spends too much time worrying about me instead of worrying about getting the bad guys. Besides, since Xander told us about the curse it’s kinda thrown a monkey wretch into things.”
“Yeah, I-I can see that. I’ve been working on fixing it, though.” She smiled at the blond. “I’ve found a few leads that look promising.”
Buffy chuckled. “Thanks.”
“Oh,” Willow snapped her fingers, “I have to go. Xander wanted me to pick up some fabric at the store downtown. Something about learning to enchant it.”
“Okay.” Hefting her pack, Buffy said, “I guess I’ll get started on that history paper.”
“Later.” Before her friend could reply, Willow was gone.
“Yeah, later.” She gave Willow’s back a smile and a roll of her eyes.
As she rounded the corner, Willow paused and smiled. “Sorry for the brush-off, Buffy,” she whispered, “but you need to go home now.”
As she neared the house, Buffy felt a tingle run up her back. Pausing, she glanced around before resuming her trek toward the door. To her surprise, the door was slightly open. Pushing it open slowly, she called out, “Mom?”
“Come in, Buffy,” came Joyce Summers’ voice. As her daughter opened the door, she could see her mother standing in the living room. She was dressed as she normally did when she went to the gallery, with the professional-looking skirt and blouse.
“You okay, Mom?” Buffy asked as she closed the door. “You’re normally at work right now. And,” she gestured behind her, “the door was open.”
“I must have left it open when our guests came in,” Joyce told her. “Anyway, I was just informed that you were the Slayer.” Her arms crossed as she frowned. “Didn’t you think that was something I might want to know about my daughter?”
“Slayer?” Buffy’s mind whirled as she tried to figure out what to do. “What’s a Slayer?”
The frown deepened. “Don’t lie to me, Buffy. I know all about it. I know why you burned down the gym at Hemery, that Mr. Giles was your Watcher, and that your powers faded right after Halloween.”
“That much, huh?” Buffy set her pack next to the door. “Look, I-I didn’t tell you because I didn’t want you to worry.”
“But it’s okay if Xander and Willow worry? Or nearly get themselves killed?”
“Uh, no. But they found out about me on their own.” She cringed as she heard her own voice. I sound like a little kid.
“And then Xander had to save your life with CPR,” Joyce went on. “My daughter dies long enough to call another Slayer and I never find out about it.”
“But I’m not a Slayer anymore!” Buffy exclaimed. “I’m just a normal girl trying to, you know, get through school.”
“A normal girl who’s dating a vampire and whose best friends are now powerful sorcerers?”
Buffy visibly wilted. “Who told you?” she finally managed to ask.
The three women sitting on the couch had been unnoticed by the teen until one of them spoke. The one in the center was dressed in a white dress that hinted at a figure that made part of Buffy whimper in envy. Her hair was long, dark, and with just enough wave to it to be perfect. Her eyes seemed black and infinitely deep. To her left, a redhead in a green gown smirked slightly in contrast to the serious look on the other’s face. Her brown eyes seemed to appraise Buffy in a way that again made her feel inferior. On the other side of the woman in white was a blond with blue eyes and a red strapless dress. She was wearing red sneakers while the other two were shoeless. And again Buffy felt like a bug in a room full of supermodels.
“You come highly recommended,” the same voice, this time identified as coming from the redhead, told her.
“Yes,” the woman in the middle spoke. “When Athena first came to me with this idea, I had my doubts, but after meeting your mother I am much more certain that this is the right course of action.”
“Wait, Athena?” Buffy blinked a couple of times. “Wasn’t that one of the geek goddesses?”
As the three women flinched Joyce corrected, “Greek, Buffy.”
“Oh, sorry, Greek goddesses.”
“Yes, well,” the redhead said after a grimace, “we are.”
“Yes.” Athena placed a hand to her chest. “I am the Goddess Athena. This,” she gestured to the blonde, “I Artemis, Greek Goddess of the Hunt. And this is Hera, Queen of the Greek gods.”
“You’re gods?” Buffy felt her mouth go dry.
“Indeed we are,” Hera told her.
“You’re not here to kill me are you?” Seeing the surprised looks she explained, “I’m, uh, I mean, I was the Slayer, and I know sometimes the supernatural goes looking for stuff like me, so –“
“Buffy,” her mother interrupted, “they’re not here to kill you.”
“Oh, good.” Shrugging, Buffy added, “I mean, I don’t know if I could have fought one goddess as a Slayer, but not being one?” She shrugged again, “I’d be toast.”
“But you would try,” Artemis said as she stood. “No matter how tired or weary of your life you would become, you would never just surrender to death.”
“Unless it was for a greater purpose,” Athena pointed out.”
“Self-sacrifice, true,” Artemis agreed. She moved to where Buffy stood then placed a hand on her head.
It felt to Buffy as though she’d missed a blink. “What happened?” she inquired.
“A blessing,” Artemis explained. “After all,” she said, “we blondes have to stick together.”
“A blessing of health,” Hera said as she stood along with Athena. “We gave it to your mother as well.”
“Think of it as a good will gesture,” Athena added.
“Buffy,” Joyce placed a hand on her daughter’s shoulder, “they have an offer for us.”
Hera looked at Athena. “I though you said she was intelligent?”
“She is,” Athena countered. “But she’s still in shock over having us in her living room.”
“Good point,” Artemis conceded.”Think carefully and don’t be afraid to ask them questions.”
Xander’s words from a few weeks before came to her mind. ”Just be nice about how you word them. Oh, and be sure to ask how much time you’re going to spend away from home.”
“Xander told me someone would be coming,” Buffy told them. “But what’s this got to do with my Mom?”
“Things have changed since I spoke to the Sorcerer Supreme,” Athena said. “At first I was going to do this alone, but I decided to see if the other two wanted in.”
“After all, it’s how it worked in that other universe you found,” Artemis chimed in.
“As for your question,” Hera said, cutting off the other two, “there is a large group of women and girls who are now waiting for a calling that will never come.”
“You mean the potential slayers?”
“Buffy,” Joyce admonished, “don’t interrupt the queen of the gods, please.”
“Thank you, Joyce.”
“These potentials, past and present, were to be used as weapons against the darkness by this Watcher’s Council. We have decided that, since the Slayer Spell is broken, that a separate destiny should be offered.” Seeing that Buffy had raised a hand, she asked, “You have a question?”
“Uh, yeah. Um, you said the spell was broken? What about the current Slayer?”
“Her powers will continue for a short while, then fade, though much more slowly than did your own.”
“Athena found an alternate reality where a group of women were brought together and wanted to see about forming them here,” Artemis told them. “I think it would be a great idea.”
“As did I. But,” Hera raised an eyebrow at Buffy, “you are not the one to lead such an organization. Joyce, however,” she smiled at the older mortal, “is. So, we have offered her the position of queen.”
“Queen?” Buffy smiled at her mother, “Go, Mom!”
“And you,” Athena put in, “would be our champion.”
The question from Xander came to her mind. “How much time would I be away from home?”
“After training,” Athena told her, “a few days at a time.”
“Giles was always big on training,” Buffy mused.
Artemis chuckled, “Xander says Rupert has been a big help.”
“You just think he’s cute,” Athena accused the goddess.
“He is cute.”
Hera rolled her eyes then looked at Joyce and said, “See what I’ve put up with for all these years?”
“They sound a bit like teenagers,” Joyce replied.
“Hey!” Athena, Artemis and Buffy protested in unison.
“So,” Joyce went on, “the job?”
“Yeah,” Buffy agreed, “what’s the what?”
