Emma Frost was created by Chris Claremont and John Bryne.
Buffy the Vampire Slayer was created By Joss Whedon and all the characters with the BTVS TV series are his as well.

Nathaniel Essex stared at the fully grown clone that was residing in the gestation tube. “It wasn't supposed to grow this fast.” He said as he checked the nutrient levels in the solution. He opened the tube to examine the clone.
“Grrkkkkk.” Essex choked out as a strong hand clasped around his throat.
“What did you do?” The Clone demanded in a harsh voice.
“You're not supposed to have a mind.” Essex choked out.
“Well I do.” The clone snapped before knocking the man out. The clone stood on unusually steady legs and looked over the data that was available to it. “Less than two days.” It muttered. It ripped the hard drives out of the computers and destroyed all the samples it could find before vanishing from the laboratory.
“What the hell?” Xander said as he watched a naked version of himself appear in front of him.
“We've got a problem.” The second Xander said.
“I can see that.” Xander nodded. “Time travel? Alternate reality?”
“Clone.” The second Xander sighed.
“Again?” Xander asked.
“Again.” The second Xander agreed. “I remember everything until about two days ago. I destroyed the samples.”
“How?” Xander asked.
“Sheets.” was the reply.
“Well lets get you dressed and some food.” Xander sighed. “Anything else you can tell me about the place?”
“I got out of there as soon as I could.” The clone admitted. “I just made sure this wouldn't happen again.”
“For that, you get the stuff Cordelia won't let me wear.” Xander said.
“Sounds good to me.” The clone grinned. “I miss the Hawaiian shirts anyways.”
“What the hell?” Logan half screamed.
“I got cloned.” Xander told him.
“We can see that.” Moira said. “What happened?”
“We can't send out our laundry anymore.” Xander's clone said. “I also need a name.”
“How did this happen due to laundry?” Kurt asked.
“Some of my hair among a large amount of other viable genetic material.” Xander explained.
“Still need a name.” Xander's clone chipped in.
“Bengali?” Xander suggested.
“Ben.” Xander's clone agreed. “What was mom's maiden name?”
“Ben Ravenson?” Xander suggested.
“Could work. Take some getting used to.” The clone said with a shrug.
“So now what?” Cordelia asked.
“Well we could always clone you, or I could travel the earth like that guy in Kung Fu.” Ben suggested.
Xavier pinched the bridge of his nose. “Will someone please pass the oatmeal? This isn't something to consider on an empty stomach.”
“Sorry Prof.” Ben said before handing Xavier the serving bowl.
After the meal.....
“So whatcha think?” Ben asked as he showed Xander a white and black variant of their fur's striping.
“Bengali indeed.” Xander said with an approving nod. His sword surfaced out of his arm and he handed it to his clone.
Ben held up the sword and shook his head. “Sorry, guess I'll have to do with other weapons.”
“But you're me.” Xander said.
“Clone. I may have your genes and memories, but not your soul. Not really.” Ben said with a shrug. “I can get used to a new skill set. Maybe take up Bengali's hammer.”
The sword pulsed in Xander's hand. “It agrees.” He said as he held up the sword once again.
“How can they be so casual about this?” Alex asked his brother.
“I don't know.” Scott sighed.
“For one thing, their senses tell them each one is Xander.” Logan said. “Kid smells identical.”
“Oh. Hard to fool your nose isn't it?” Alex asked.
“Only a strong psychic or the right chemicals can throw 'em off.” Logan said. “Don't know how I'd react to being cloned.”
“But how did the memories come about?” Alex asked.
“That's a good question.” Moira said. “Genetic Memory is a possibility but I'd have to examine Xander's genes more thoroughly and he doesn't want me to do that.”
“I have a right to some privacy.” Xander said. “My genes are my own.”
“Not anymore they're not.” Ben countered. “Still, I agree with him. We don't need people tinkering around with our genome. Not again.”
“We're going to have to set you up with an identity.” Xander sighed.
“We've got the needed computers do get the job done here. May as well deal with it after school.” Ben suggested.
“Point.” Xander sighed. “You'll still be here right?”
“Not like I have anywhere else to go except Sunnydale.” Ben told him.
“And now Xander has a duplicate that's just like him!” A copy of Jamie Madrox told Kevin MacTaggert.
“That's pretty neat. Think I could see him at dinner?” Kevin asked.
“He's here in the house now! I could go get him.” Jamie offered.
“That's sounds like a good idea. Hurry back.” Kevin grinned.
“Okay!” Jamie said before heading out of Kevin's room.
Kevin grinned. Jamie was such a good friend leaving a double behind like this for him.
“Jamie, what are you doing in the house?” Ben asked the younger mutant.
“I'm a copy. I've been spending days with Kevin. He gets lonely.” Jamie said. “He wants to meet you.”
Ben rolled his eyes but closed his book and stood up. “All right, let's go.” Ben grinned.
“Think we can go outside and play early today?” Jamie asked him.
“Should be able to arrange it.” Ben told him as he messed up the kid's hair.
“Charles, he's out playing with my son.” Moira fretted.
“He's a fully capable adult Moira.” Charles assured her.
“One who didn't exist two days ago.” Moira countered. “Genetic memory or not, he's out there playing with my son and one of Jamie's duplicates.”
“Children can be a good judge of character Moira. He let me scan him. There's nothing hidden. He's safe.”
“Is he stable? What if his genes begin to unravel?” Moira asked. “He won't let me examine him.”
“Xander originally would have reached adulthood within a week of conception. This isn't much different than that.” Xavier told her. “If you want to keep a closer eye on your son, go join them.”
“You just want a blood sample.” Charles half teased.
“Wouldn't you?” Moira asked.
“Point.” Xavier sighed. “Let him be Moira. He's a victim of this.”
“”I know Charles. He's a victim as much as that Parker boy is.”
“What have we wrought Moira?” Charles asked her.
“It wasn't just us. Technology's at a turning point. An evolution of it's own.” Moira said.
“But will we survive it?” Xavier mused.
“Time will tell.” Moira sighed. “I'll be outside. It's a nice day out.”
“Dad we've got to go.” John Jameson said to his father.
“I'll be there in a minute.” Jonah said as he put a few more things into the shredder. “You're really looking forward to this shuttle trip aren't you?”
“I've got to get to Florida and the housing there. We launch again in a few weeks.” John told him.
“How many times can you go back up?” Jonah asked him.
“Two more times depending on the duration. The bone loss is still something they haven't fully countered. That's what I can look forward to unless someone outfits the shuttle with some sort of artificial gravity. If they've developed it, it hasn't trickled down to NASA yet.” John told his father.
“Blasted super scientists.” Jonah muttered.
“There's the grump that raised me.” John laughed.
“You okay?” Cordelia asked her husband.
“I've been better. I've got a twin now. Despite how we're acting, this is really screwy.” Xander sighed.
“Well, you've got another Thunderian on your side.” Cordelia told him. “That's good right?”
“The sword didn't respond to him like it does me.” Xander told her. “Though it did give him a hammer.”
“So he's not a bad clone then.” Cordelia told him. “We'll deal Xander. It's what we're best at.”
“I've got another brother. Weird.” Xander said with a far off look on his face.
“Yes, and he's inherited your dress sense. He can have all of your older clothes.” Cordelia told him.
“Somehow, I don't think he'll mind.” Xander said softly.
Cordelia smacked him in the arm.
“Ouch....” Xander muttered as he rubbed the appendage.
Cordelia shook her hand. “You're getting denser aren't you?”
“I am.” He admitted.
“When is it going to stop?” She asked.
“I don't know.” Xander told her. “I honestly don't know.”
Back at the mansion....
“You're staring.” Ben said from behind his book.
“Sorry.” Moira said quietly. “Why won't you let me get a sample? You could be unstable.”
“I'm not.” Ben growled. “You actually think I want someone else getting a hold of my DNA? Get real.” He said before vanishing from the room, taking the book he was reading with him.
Moira sighed. “Things were simpler on Muir Island.” She said softly.
“Why are you in here?” Xander asked Ben after entering his and Cordelia's bedroom.
“Moira was bugging me.” Ben called down from where he was floating. “If I was unstable you could tell right?”
“If not me, then the sword would have said something.” Xander agreed. “You're fine. You're just.... new. Let's get you a new identity huh?”
“Twins, separated at birth?” Ben asked.
“Works for me.” Xander said with a shrug. “We're needed in Forge's lab for this. He's got the best stuff to put you into the system.”
“How much you want to bet my prints are barely different than yours?” Ben teased.
“Hopefully they'll be enough to differentiate.” Xander said. “Let's go.”
“Let's.” Ben said as he vanished from the room.
“Yeah.” Xander said, following him.
Fifteen minutes later....
“Done.” Forge said as he printed out the necessary documents on his jury rigged forging printer.
“Excellent.” Ben said as he reviewed the materials. “Thanks Forge.”
“I owe you. Well I owe Xander, you know.” Forge said, stumbling slightly over the concepts.
“It's cool.” Ben said. “Thanks for this man.”
“Not a problem. So now what?” Forge asked.
“I'm going to hit the road.” Ben said. “There's a lot of things I can do out there that I can't in Bayville.”
“Have you always felt this way?” Cordelia asked Xander.
“I plead the fifth.” Xander said while Ben laughed.
