I don't own the X-Men, those belong to Marvel Comics and were created by Stan Lee and Jack Kirby
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.
The Thundercats were created by Ted Wolf and currently belong to Warner Brothers, at one point in time Marvel comics did do a run of the them in comics form, although DC comics do them now.
A little short, but here it is.
“Of course! It's so simple now!” Norman Osborn laughed as he'd finished manipulating the formula. He'd been up for 36 hours and after a few timed doses of Globulin Green that not only upped his physical stats but increased his mental capacity, he'd finally completed the Oz formula. Now he just needed to brew it. “Should I dose again?” He mused. “I am tired. After I take the Oz formula I won't need the Green..... What's the harm?” He laughed.
He downed another vial of the green formula and began the process of creating his masterpiece.
The Daily Globe.....
“What have you got for us this week Pete?” Robbie asked the young photographer.
Peter grinned as he handed Robbie a folder full of various shots of both Spider-Man and Spider-Woman in action. “Whatcha think?” Peter asked Robbie.
“I think your girlfriend slipped in a little extra.” Robbie laughed as he held up a photo of Mary Jane in a bikini.
Peter blushed. “Sorry Robbie.”
“It's fine. You've got a real looker there Peter.” Robbie told him. “I've made some new connections here at this paper. You think Mary Jane would be interested in modeling?”
“That'd be up to her, but I can ask her.” Peter told him. “So about the shots?”
“Standard fee, and I think we can use two of them for file photos. How'd you get so close?” Robbie asked.
“I didn't, I got a new telescopic lens.” Peter grinned. “Not bad huh?”
“You've got some real talent Peter. You interested in working the state football championship this year?” Robbie asked him.
“Tell you what, if Midtown makes it, I'll photograph their way to the top. If not, let another reporter cover it.” Peter offered.
“I'll hold you to that Peter.” Robbie told him as he wrote out a note. “Take this to Betty, she'll get you your check.”
“Awesome.” Peter grinned. “This is way more than what I used to get paid.”
“You earned it Pete.” Robbie told him.
“You okay Jean?” Scott asked his girlfriend.
“Huh?” Jean said as she looked over at Scott. “Sorry, I've been spacing out a bit lately. My range has been increasing. Did you know that Principal Kelley wants to run for Mayor?”
“Your powers are growing?” Scott asked. “That's great.”
“It's a headache really. It's just not me though, Emma's powers are growing too.” Jean sighed. “I'm starting to think we're developing at the same rate because of the link the professor had us do last year.”
“Is having a friend who's an equal in power a bad thing?” Scott asked her.
“What if we aren't always friends?” Jean countered. “We get along great now, but some of the things we see in the minds of others....stick around. It's.... weird.”
“I'll have to take your word for it Jean.” Scott said. “We'd better get to class, I don't want another tardy.”
“Still.” Jean grinned. “The broom closet was totally worth it.”
“Not saying it wasn't, just that we were tardy.” Scott laughed.
That day at lunch.....
“Someone is struggling with something.” Jean said as she rubbed her temples. “It's like he's fighting some inner beast. He's broadcasting.”
“He's... upstairs?” Emma said as she concentrated. “He needs help.”
“Let's go then.” Scott said as he stood.
“Where's the principal?” Fred asked.
“He's in his office having some soup.” Emma said after a moment's concentration. “We're clear to go check this out.”
“You four be careful.” Kurt said to them as they headed upstairs.
“It's Mr. McCoy!” Scott said as the found the teacher in the men's room reciting Shakespeare.
“Kids, you need to get out of here.” Hank McCoy growled as he clutched his head before going back to reciting lines.
“He's been suppressing his mutation with chemicals. We need to get him to Dr. MacTaggert.” Jean said as she concentrated.
“We can't exactly sneak him out in my car.” Scott mused. “I've been meaning to try this out since Forge gave it to me.” He said as he flipped open the face on his watch. “Call Xander.” He said into it.
“Cell phone watch?” Fred asked.
“Yeah.” Scott said as it began ringing.
“I'm knocking him out.” Emma said as she touched McCoy's head.
“What's up?” Everyone heard Xander's voice say from Scott's watch.
“We need an emergency transport from the school to the mansion.” Scott told him.
“Where are you in the school?” Xander asked.
“Third floor, west wing. Men's room.” Fred recited.
Everyone looked at him.
“What? I know which way West is.” Fred said.
“Don't ever change Fred.” Xander laughed as he hung up the phone. He entered the bathroom a moment later.
“What have we got?” He asked as he stared at the unconscious teacher. “Is he evil?”
“He's been suppressing his mutation with a chemical cocktail.” Jean told him. “It's starting to fail.”
“That or his mutation adapted.” Xander mused. “I'll get him over to the mansion. You four, get back to whatever it is you're supposed to be doing right now.”
“Thanks Xander.” Scott said.
“It's fine. Cordy's going to be pissed at me for skipping out on lunch but I'll manage.” Xander said as he picked the man up. “He's pretty heavy for his size.” He said as he vanished from the school.
Xander reappeared in the main entrance of the mansion. He hit the intercom and called for Dr. MacTaggert's location.
“I'm in my lab Xander. What's going on?” Moira asked.
“I'll be right there. I'll explain when I get there.” Xander said before teleporting down a few levels.
“What's with him?” Moira asked as Xander appeared carrying a large limbed man.
“He's been suppressing his mutation with something and it's not working anymore. Emma knocked him out because he was struggling with his inner beast.” Xander said. “You know if I didn't know better I'd say he smells almost like a cat.” Xander told her.
“Get him on the table.” Moira instructed.
He did and Moira had him strapped down and took a blood sample.
Moira examined it and found something surprising. “I don't think I've ever seen such a high concentration of Mutant Growth Hormone.”
“But he's an adult.” Xander said.
“I don't think it matters at this point.” Moira said. “If he's been suppressing his mutation then it's been building in his system. He might have even made his mutation worse by doing this.”
“Now you tell me.” A voice said from the table.
“Mr. McCoy right?” Xander asked him.
“Yes. Can you let me go?” Hank asked as he struggled with the straps. “What are these made of?”
“A new polymer chain. It's much stronger than the average seat belt.” Moira told him. “From what I'm reading your mutation will come forth sometime tonight. That's if you dose yourself again with whatever it is that you've been taking.” Moira said.
“And if I don't?” Hank asked.
“We'll try to make this as gentle on you as possible. If you tell me what you made, I might be able to make a counter agent.” Moira told him.
Hank McCoy took a deep breath and rattled of a chemical formula that Moira began inputting into the computer. Moira whistled. “You're some kind of fancy biochemist there Mr. McCoy.”
“I dabble.” Hank admitted.
“Am I needed?” Xander asked her.
“You might be when we inject the counter agent.” Moira told him.
“How long will that be?” Xander asked.
“About a half hour for me to make it.” Moira said.
“Great, just enough time for me to go apologize to my wife.” Xander grinned. “I'll be back.”
“Strange lad.” Hank said after the teen vanished.
“You could say that.” Moira snorted.
the Sushi Shop...
“Where have you been?” Cordelia asked her husband.
“Sorry. A thing came up at the school.” Xander told her. “I've got to be back at the house in a half hour.”
“Well don't just sit there, eat your sushi.” She told him. “It's getting warm.”
30 minutes later.....
“You're back.” Moira noted as Xander and Cordelia entered the lab.
“We are.” Xander said with a nod. “How's the formula coming?”
“It's done. It'll gradually bind to the chemicals in his system. It should take about ten minutes.” Moira told him as she prepared the injection.
“Let's get this over with.” Hank grimaced.
Moira gave him the shot and turned on her video camera.
Xander and Cordelia watched as the man struggled against the restraints. His canines grew and his arms lengthened slightly. His body thickened and Xander and Cordelia rushed to loosen the straps so he wouldn't be crushed under the pressure. Next, the hair on his arms and his head turned blue. His ears became slightly pointed and blue fur started growing all over his body and his shoes split at the seams.
“Wow.” Moira said. “He's a regular beast isn't he?”
“You could say that.” Xander said softly. “Compare his DNA to mine would you?” Xander asked her.
“What would that prove?” Moira asked.
“I need to know just how feline he is Dr. MacTaggert. I can sense him.”
“Why would that be a problem?” Moira asked him.
“I have dominion over most cats Moira.” Xander told her. “If he's in a primitive mindset...” Xander trailed off. “If he's nothing more than a beast, I can control him.”
“Let's wait and see about that Xander. I'm getting some unusual brainwave activity. If I'm right he's actually going to be smarter than he was before this.”
“That's good news.” Charles Xavier said as he walked into the lab. “I've known Hank for a few years now. Thank you for helping him.” Charles said as he scanned the latest mutant's mind. “You needn't worry Xander. He's still there.”
“Good.” Xander said with a relieved sigh. “Think we can get him fitted with an image inducer before he's reported as missing?”
“We can certainly try.” Xavier smiled.
“Is everything okay?” Scott asked as he and the others went inside the house.
They found a blue and fuzzy Hank McCoy sitting at the kitchen table sipping a cup of tea.
“Things are just fine, though the fangs will take some getting used to.” Hank said. “As will the increase in body hair. Lord help us all if I start shedding.”
“So you're okay?” Scott asked him.
“In time.” Hank told them. “I'm just glad that I can go back to my job thanks to the latest in holographic technology.” Hank said as he turned on his image inducer so he appearance was the same as he'd been just that morning. “See?”
“That's great news Mr. McCoy.” Scott said, relieved. “From what Kurt tells me you're a great teacher.”
“I certainly try.” Hank grinned. “I also think you'll be seeing more of me around here. I didn't' realize all the potential research I could be doing here.”
“What sort of research?” Scott asked.
“All kinds really. I don't have this kind of equipment back at my apartment.” Hank grinned. “Plus it'll give me the chance to stretch my legs so to speak.”
“Welcome to the family.” Fred smiled.
“Thank you young man.” Hank said before sipping his tea. His head turned as he watched a glint of silvery white go by outside near the kitchen window. “I think I could get to like it here.”
Principal Kelley's Office, the next day....
“You just abandoned your post during the middle of a school day McCoy.” Kelley said to the science/PE teacher. “That can't happen again.”
“I'm sorry sir. It was a family emergerncy.” Hank told him. “I'll make sure to notify you if I need to leave again.”
“You do that. We had a hell of a time finding a substitute during the middle of the day like that. It was chaos! I can't have chaos in my school.” Kelley half ranted. “Consider yourself on my watch list. You're a good teacher and a good coach, but that doesn't mean you're irreplaceable.”
“Understood sir.” Hank said softly. He really didn't like this man too much. Something about him rubbed his fur the wrong way.
The Goblin's Nest....
Norman Osborn chuckled as he finished making the formula. He loaded up the syringe. He'd adapted the formula to his own genetic code. It'd would enhance his own attributes and enact a permanent genetic change.
He injected the formula. It hurt worse than the calculations said it would. Every cell of his body felt like it was on fire. There was pain and then..... white.
The Goblin's nest exploded in green fire causing the warehouse it was located under to collapse.
