This is Percy Jackson and co meets my story. Might not be overly interesting 'cos the last one flopped. But if you could read and review I'd be really grateful.

Some of the creatures on here are Lizardians. I'll do my best to describe them, but I do have pictures up on Deviantart if anyone wants to see them. Just PM me and I'll give you my Deviantart name.

I do not own Percy Jackson- unfortunately- but Louisa is my OC. I do own my story, obviously, which is untitled at the moment.

"Get off!" Louisa struggled against her brother, Annabeth and Leo's combined weight. Of course, after the strange bright blue light she had to end up at the bottom of the pile. "I said off!"

"Dude! Michael, what'd ya do?"

"I don't know, Alfie. Don't start!"

"I'm tellin' Mom!"

"No, don't- Alfie!"

"I got him!" There was dull thud followed by laughs and the sounds of a play fight.

The demigods sat up. They were in some strange house. It had four levels and was strangely circular, as if it wasn't a house. The brick pillars were dark red, the floors dusty brown. The lake in the middle was a figure-of-8-shape with a wooden bridge with reinforced plastic panels in the sides with strange symbols in the middle and around the edges. There was a 50 inch flat screen TV on the wall to their left, with three four seater black leather sofas around it, with a dark oak coffee table in the centre. To the right was a huge wide rectangle table, which could seat three on the ends and eight on the sides. There were no windows.

"What is this place?" Leo asked. The twins shrugged. Percy looked at Annabeth and saw that she was taking in every detail of the architecture. "Dude, what are those?"

Wrestling on the floor and the source of the play fight sounds were two strange creatures. It was hard to tell what they were as they rolled about the floor, but they were green, one a darker shade of green than the other. The one with the darker skin was clearly a boy, his dark brown hair streaked with raven short and windswept. The girl he was wrestling with was of some relation, her hair the same dark brown as most of his. They weren't human at all, more lizard or salamander like with smooth skin and tails. They were dressed in human clothes though- the girl was in simple jeans, not skinny and a hooded jacket, the zip done up to her chin. The boy wore a hooded sweatshirt, black with red sleeves and a red hood. He wore black tracksuit bottoms that were similar to Louisa's. Their feet were foot shape, but they didn't have toes. (Look at pictures on Deviantart- PM about those).

"Oh, will you two stop it!?" Out of one of the rooms on the ground floor, an older female version of the two creatures stormed out. She wore similar tracksuit bottoms to the boy creature, but a dark blue instead of black. Her T-shirt was of Hollywood Undead- Percy noticed Louisa instantly approved the strange creature.

The new creature noticed them, her brown-green eyes widening in surprise. Then they narrowed in suspicion. She looked round at a guy the demigods hadn't noticed before, her dark brown hair streaked with auburn swinging over her shoulder. "Michael…" She warned.

"It was an accident, Vi, honest. Alfie wouldn't leave the tech alone and I tried to stop him, but you know what he's like…" Vi looked over her shoulder at the two children still rolling about on the floor.

"Alright, who are they?" She nodded at the demigods. Michael shrugged. "You haven't asked them?" He shook his head, smiling sheepishly. "Do I have to do everything myself?" Vi grumbled.

She moved towards the demigods. Leo saw a friendly gleam in her multi-coloured eyes.

With the universal friendly gesture of offering her hand, Vi properly introduced herself. "Violet." She smiled. "Who are you?" Louisa shook Violet's hand warmly.

"I'm Louisa 'n' I love ya shirt." Violet looked down at her T-shirt and grinned.

"Alfie got it for me." Violet motioned at the pair on the floor, who had retreated into a feeble poking war and giggles. "Are you two related?" She pointed at Louisa and Percy. Leo noticed that Violet had two fingers and a thumb on each hand.

"Twins." They said together, grinning cheekily.

"Cool. I'm a quadruplet."

"A what?" Leo asked smartly. Annabeth sighed.

"Like twins, but four of them instead of two." Leo winced.

"I feel sorry for your mom." He said. Violet grinned.

"I'm the youngest of a big family."

"Very big family." The boy creature piped up.

"Alfie, shut up."

"Sorry, Mom." Alfie fell silent and continued to poke his friend.

"I'm Annabeth, this is Leo and he's Percy."

"Nice to meet you all."

"How did we get here?" Annabeth asked. Violet shrugged, turning to look at Michael.

Michael was in his late thirties, early forties, but he was in good shape with clever blue eyes that took in every detail of the demigods. He had salt and pepper hair, reminding Percy of Paul and of home. Michael was dressed in smart casual clothes- a crisp, white shirt, the top button not done up. He wore blue jeans that were smeared with machine oil- that got Leo's attention. Michael's white trainers were pristine, which seemed a bit odd.

"Vi, I told you. Alfie was on the loose again."

"As he often is." Violet sighed. "Alfie and Daisy, here now." The two on the floor grumbled, giving each other last, defiant pokes.

Alfie stopped at Violet's right and Daisy on her left.

"Are they siblings?" Annabeth asked.

"Cousins. Kind of. But they grew up together, so… adopted siblings." Violet settled with.

Alfie stuck his hand out.

"I'm Pita." He grinned.

"No, I'm Pita!" Louisa argued. Alfie seemed a bit taken aback.

"Pita?" Percy asked, as clueless as ever.

"Pain in the ass." Alfie and Louisa translated together. Alfie blinked at her, his deep brown eyes innocent and confused. He smiled weakly.

"Take it easy on him, he just got back." Violet ran a hand through Alfie's hair, a sad look overtaking her eyes momentarily.

"Daisy," Daisy said, holding her hand out. Annabeth shook it warmly. "I'm just the medic-in-training."

"A good medic in training." A new voice. Another lizard/salamander creature exited from a different room on the ground floor. Daisy grinned at him. They had the same, jade green skin that radiated with health and happiness. They also had the same hazel eyes, but his hair was a dark brown, so dark it was almost black. He wore a plain, dark purple T-shirt and flannel jogging bottoms.

The newcomer noticed the demigods and studied them curiously.

"New friends. Michael's fault." Violet said simply.

"Was not!" Michael protested. Violet smirked at him, folding her arms stubbornly. "I'm going off you." He turned and started to walk off.

"You've been goin' off Mom since ya meet her when she was fourteen!" Alfie called after him.

"Alfie, shut up!"

"Make me!" Alfie challenged good humouredly. Michael didn't reply to that, closing the door to a third room on the ground floor.

"Why's everythin' on the ground floor?" Louisa asked.

"Important rooms, like the infirmary and Michael's office, are on the ground floor. Most bedrooms are on the other floors. I'll give ya all a tour later." Alfie stepped forward and threw his arms out as if to grace the heavens, reminding the twins of Leo's performance from the other week.

"You have some explaining to do." He pointed accusingly at them. Violet grabbed Alfie by the shoulders and steered him around.

"Go and find Jo." She told him. "Daisy, keep an eye on him please." Daisy nodded and followed her cousin, tucking her arm through his.

"One quick question first." Louisa spoke up.

"Shoot." Violet grinned.

"What are you?" Violet laughed as if she had been expecting this question.

"Well, short term, mutants. Fancy term, Lizardians."

"Mutants?"

"No, we don't go around destroying cities and stuff. We're the good mutants."

"So bad mutants go around destroyin' cities 'n' stuff?"

"Yup and it's our job to stop them. Now talk. Or I'll call Alfie back. He's in the most annoying mood possible today." Leo smirked.

"I can so challenge that."

I know this chapter was mostly introduction and there will be a few throughout the story 'cos there are a lot of characters. But please carry on reading it, 'cos I've got some good ideas (well I think they're good ideas, but hey).

So what'd you think? Love it, hate it, wanna throw a nuke at it? What? Please tell me!
