Chapter 1

"Aqua?" said a voice.

"Yes, Pyro?" answered the girl called Aqua. Silence filled the air. "Pyro?" Aqua asked again.

Behind the glass wall, two people observed the two little girls. The two girls were twins and were considered dangerous. One of the observing people spoke.

"We have to seperate the two girls. They're too close," the voice said.

"If we seperat them, Pyro will... well, destroy the lab," the other replied.

"Put them in the chamber room. Fill it with carbon monoxide." the first voice said coldly.

"I'm afraid to say that we can't do that, Mr. Newman," The voice replied grimly.

The voice called Newman said, "And why is that, Ms Suris?"

"Do you remember Last week when I told you that it was critically damaged?" Ms. Suris replied carefully.

"Yes, what about... Pyro?" Newman said, surprised. Ms. Suris nodded. "All those holes and damages to the computers...? Pyro did all that?" Mr. Newman asked.

"Yes, sir. Pyro is very clever and her intelligence is beyond imagination." Ms. Suris said as she read off a clipboard in her hand.

"Aqua? What about her?" Mr. Newman asked

"Her intelligence is the same as her sister's. She's... well, almost as sly as Pyro." Ms. Suris said as her brows knitted together.

"Very well. Put the children in the tank lab. Put them to sleep and fill it with water." Mr. Newman sighed heavily.

"Yes, sir." Ms. Suris nodded her head.

She walked to a steel door that led to the girls' room. She put her hand on the scanner. The machine hummed and the latch lifted. Ms. Suris walked in. The room was very plain and completely white. The only color in the room were the two little girls.

They both looked up the the woman, eyes curious.

"Let's go girls." Ms. Suris said in a falsely sweet voice. She held both their jands and guided them out of the room. Both girls looked all around them.

Ms. suris came to another steel door. A lowly scientist opened the door for her. Scientists of all ranks were preparing the tanks. When they were fdone, oxygen masks covered the girls faces as water filled the tanks. Very slowly, the girls went to sleep.

8 years later

Pyro's pov

All I saw was darkness. I didn't know where I was.

'Where am I?' I asked in my head. 'Aqua? Are you here? Can you hear me?' I called out.

Silence. I slowly opened my eyes. Water filled my eyes. I blinked several times to get used to the feeling. I was in the tank next to my sister, Aqua. The liquid ws clear and clean. I breathed deeply. I looked around my cylinder prison. I saw Aqua in her tank. She was still asleep.

I turned to the left. I saw scientists. I grew angry. Oh, how I hate scientists! They put us through hell for the past two years!(A/N pyro doesn't know how long they've been asleep) I decided to escape this hell for good.

Normal pov

Pyro started to change. She was changing into a dinosaur. Her body grew rapidly. The glass broke under the pressure. She roared when she finished 'shapeshifting.' She had become a T-rex.

Quickly destroying the lab, Pyro returned to her human form. She was careful not to hurt Pyroas she ran out of the room and to freedom...

Pyro went from rooftop to rooftop, carrying Aqua, who was still out cold. Pyro stopped when she felt Aqua starting to stir. Aqua opened her eyes as Pyro set her down.

"What... what's going on? Where are we?" Aqua asked, very confused.

"We're in England." Pyro said.

"England? How do you know?" Aqua asked.

"Remember the large clock called Big Ben?" Pyro asked Aqua.

"Yeah, I remember that. Mom used to read to us about it." Aqua said.

"You can see it from here." Pyro said, pointing. About one mile away was Big Ben.

"So what do we do?" Aqua asked.

"I'd say hijack a train and cause a bit of chaos," Pyro said, grinning widely.

They were walking around, deciding on which train had the most people on it. Pyro saw an unusual group. They had owls on their trolleys and their clothes hardly matched. Pyro pointed them out to Aqua. They quietly followed the strange group.

"Ok, you know what to do," said the one with a bowler hat. His voice was gruff and short.

The ones with the trolleys slowly went through the stone pillar between platforms nine and ten. . Pyro whispered to Aqua, "Let's follow them."

Aqua nodded, her curiosity growing. The ones without trolley walked away casually. Pyro and Aqua looked around and went through. The next thing they knew, they were sneaking onto a scarlet red train called the Hogwarts Express.

They entered a small room that had seats in it. Pyro was the first to try the seats. They were squishy and soft.

"Try'em, Aqua!" Pyro said excitedly.

Aqua cautiously sat on the seats. She squealed in joy. They started to laugh. They stopped when the door opened. In the doorway were three people. The tallest one was a red-haired boy that had freckles and was lanky. The second was almost as tall as the red-haired boy. He had untidy black hair and a scar in the middle of his forehead. the last one was a girl with very bushy hair. In her arms was a large ginger cat.

"Hi. Are you first years?" the girl asked, her British accent clear in her voice. Pyro and Aqua just looked at each other.

"What's wrong with your eyes?" the red-haired boy blurted out, pointing to Pyro.

"Ron!" the bushy-haired girl snapped.

"They change with my mood." Pyro said dangerously.

"Pyro, be nice." Aqua said, narrowing her eyes.

"My name is Hermione Granger." the bushy-haired girl said sweetly.

"Ron Weasley." The red-haired said as he sat down.

"Harry Potter." the other boy said. Him and Hermione sat down.

"Name's Pyro." Pyro said, relaxing.

"My name is Aqua." Aqua said with a smile.

"Why are you here?" Harry asked.

"We're-" Aqua started.

"First years." Pyro cut in. Aqua continued to smile.

"What house do you want to be in? There's Hufflepuff, Slytherin, Ravenclaw and Gryffindor." Hermione said.

"Gryffindor." Aqua said.

"Slythern." Pyro said.

The others looked surprised. They sent each other glances.

"What makes you say that?" Harry asked, suspicious.

"It's-" Aqua started.

"Natural." Pyro finished.

"Duh!" they chorused.

"You two sound like Fred and George." Ron groaned.

"Who are they?" Pyro asked.

"My twin older brothers." Ron groaned.

The compartment door suddenly opened. A boy who had sleek,blond hair and a pointed chin stood between two thug-like cronies.

"What?" Harry asked aggresively.

"Manners, Potter, or I'll have to give you a detention," drawled the boy. "You see, I unlike you, have been made a prefect, which means that I, unlike you, have the power to hand out punishments."

"My, my, aren't we pushy?" Pyro said slyly. "What's your name, girlie mouth?"

The boy looked at Pyro with a sneer. "Draco Malfoy." he coldly.

"Very well, Malfoy. I strongly suggest you leave," Pyro said, slowly standing.

"Not if I put you in detention." Malfoy said. His cronies sneered.

"You know," Pyro said as she stood barely two inches away from Malfoy, "my ancestors were Japanese samurai. Do you know how to honor a samurai?" Pyro's voice was low and dangerous.

"Kill them with poison." Malfoy said, fear rising in his voice."

"No." Pyro said. SWISH. A shiny katana was suddenly at Malfoy's throat. "You cut off their head. They usually show it off to their friends. Leave now or else I'll do it to you." Pyro said threateningly.

Pyro put her sword back into it's sheath. Suddenly, Malfoy had his wand pointed at Pyro.

"Impedimenta!" he cried. A flash of red light shot towards Pyro. It hit her but nothing happened. Pyro blinked several times before hearing several other voices.

Malfoy and his cronies were soon knocked unconscious. Pyro kicked them all out of the compartment. Pyro returned to her seat.

"Who are you?" Harry asked.

"I already answered that. Why don't you ask a question you don't know the answer to?" Pyro grinned, showing her fangs.

"What are you?" Hermione said coldly, pointing her wand at Pyro.

Pyro and Aqua looked at each other. Neither answered.

"What are you? Answer me or else I'll hex you." Hermione said, thumbing her wand.

"We don't know." Pyro said finally.

"Don't know what?" Harry asked.

"What we are." Aqua said.

"All we know is that-" Pyro started.

"We can shapeshift." Aqua finished the sentence.

"At will." Pyro stated simply.

"You're a Metamorphmagus." Harry said slowly, remembering Tonks.

"Not exactly." Aqua said slowly.

"What's a Megamorphgus?" Ron asked.

"It's Metamorphmagus. It's when you can change your appearance at will." Hermione said matter-of-factly.

"What do you mean that you're not exactly a Metamorphmagus, what's different?" Ron asked, confused.

"I can make illusions. I'm very good at it." Pyro said proudly.

"How good are you?" Harry and Ron said together.

Pyro's now black eyes narrowed in an evil way. "I have caused people to commit suicide to preserve their sanity." She grinned wickedly. Ron and Harry gulped.

"What can you do?" Hermione asked Aqua quickly.

"I can communicate with centaurs. They like me."

"Why weren't you effected by magic?" Harry asked.

"Hmm? What do you mean?" Pyro asked.

"That spell... it should hve knocked you to the wall." Hermione said.

"Hmm... we might be immune to it. Anyway, we have to go." Pyro saaid as she go up.

"Where're you going?" Ron asked.

"Explorin'" Pyro said winking as she closed the compartment door.

"Where are we going?" Aqua asked her sister.

"I've heard that Hogwarts is a very large castle. And it's enchanted. Are you catching on." Pyro smirked.

"I do. Let's fly there." Aqua said.

They went and managed to find a window large enough to allow them to leave. They changed into harpies and followed the railroad until they came upon Hogwarts. It was noon when they arrived.

"Well, let the chaos begin!" Pyro said as they entered the castle.
