Willoffire123: I'm back everyone! And ready to go! I am very sorry that I haven't been posting chapters very often. I had writer's cramp, or writer's block. Maybe it's both.

Terry: You're confusing

Harry: That's kind of the point.

Willoffire123: See Terry, after being stuck with each other for so long, Harry and I understand each other.

Terry: I'm scared.

Harry: Just go with it. It'll make your life so much easier.

Willoffire123: I told you. Harry understands me.

Harry: I still hate you though.

Willoffire123: Yep! And there's nothing you can do about it!

Harry: Willoffire123 doesn't own Harry Potter or Batman Beyond. After you're done reading this chapter, willoffire123 would be very happy if you could vote on the poll on her profile page.

Terry: Now I'm really scared.

Willoffire123: On with the chapter!

Harry

"Hey Luna, mind if we sit here?" I asked, pulling the compartment door open.

She shook her head. "Not at all."

Once Neville, Ginny and I had sat down, I noticed that Luna wasn't alone. Terry Wayne, the boy from Gotham whom we had met in Diagon Alley, had one arm on the armrest and his chin resting on his hand. He looked like he was sleeping.

"Terry!" I exclaimed. Terry awoke with a jump, gave me a grin, then went back to sleep.

"Do you know him?" Ginny asked me after we had sat down, our trunks safely stored away in the luggage racks above our heads.

"We met him in Madame Malkin's shop. He's an exchange student from America," I explained.

"What year is he going to be in?" asked Neville.

"Our year," I answered. "If he's put in Gryffindor, he'll be in our dorm too."

"Where's he from in America?" asked Ginny.

"Gotham City," I answered. "He said he gets himself into a lot of trouble in Gotham, along with his girlfriend."

"Well obviously," said Ginny. "I heard that Gotham has the highest crime rate in the U.S."

I was about to respond when the compartment door opened. There in the doorway stood a girl with such shockingly platinum blond hair that it looked almost blue, and lavender eyes, and a much shorter Asian boy who was completely bald.

"I'm sorry, could we sit here? Everywhere else is full," said the girl.

"Come on in," said Ginny.

After the pair had put away their luggage, they introduced themselves.

"Hi. We're exchange students from America. My name is Marina; I'll be in the sixth year. This is my close friend Kai. We both studied under the same instructor. Kai will be in the third year," said Marina.

Kai bowed in his seat. "It is a pleasure to meet all of you."

Ginny smiled. "Likewise. If you're both exchange students from America, do you know Terry here?" she asked, nodding in the direction of Terry, whom was still sleeping.

Marina's eyes widened slightly. "Yes, we do know him. Has anyone woken him up yet?"

"I did. I wouldn't do it again though. He jumped when I called his name," I warned.

"That is because you did not wake him the correct way," said Kai.

"Here, this is how you do it," said Marina. Then she shook him vigorously.

"Terry! Wake up!" she ordered.

Terry woke with a jolt. "Marina? What are you-"

"Could we talk to you in the hall?" asked Marina. Terry agreed and the three of them headed out into the hall.

"Well? Shall we eavesdrop?" asked Ginny.

"Normally I'd say yes. But we just met them. Eavesdropping would be rude," I said; and so we waited in silence. Then Neville mentioned O.W.L's, giving us something to talk about until our three new friends came back inside.

MEANWHILE

Terry

"What are you doing here?" I demanded.

"We're here for the mission," said Marina. "Kal needed to send in at least one of us to back you up. We were the only two besides you who could pass as students."

"What about M'gann?" I asked.

"She can not keep up a transformation for a long enough period of time for this mission," said Kai-ro.

"And she can't come looking like herself. Her skin is green. Every single person in Hogwarts is going to notice a girl with green skin," said Marina.

"Did you give the mission report to Dumbledore?" asked Kai.

I nodded. "We have a problem. The cult that we were hired to guard the school against is planning an attack. One of the students whose father is a part of this cult has been designated the job of finding a way for the cult to get into Hogwarts. He has an idea, but the chances of it working are very slim at the moment."

"At the moment?" said Marina, eyebrow raised.

"Yes, at the moment; and I'm not willing to overlook that chance. I'll keep an eye on him for now. Our main focus is keeping the rest of the students safe," I explained.

At that moment, Ron stuck his head out of the compartment.

"Oi! We'll be arriving at Hogwarts soon. You lot better change into your robes," he informed us.

"Fine," I told him. "We'll go change in the bathroom. Be back in a sec."

As we left, I could have sworn I heard Ron mutter to himself. "I'm never getting used to the American language."

I chuckled. "You'll have to get used to much more than that, Wizards."

AT HOGWARTS, IN THE GREAT HALL

Terry

"I wish they'd stop staring at us," I muttered to Marina.

"Oh, you'll get over it. It's part of the mission," she muttered back, fixing her attention on Kai, who had just sat down on the stool.

"I know where I would like to put you, young one, but I have my orders. Hmm, yes, this will do quite nicely. GRYFFINDOR!" called the magical hat. Kai hopped off the stool and calmly sat down at what must have been the Gryffindor table, the people at the table cheering like crazy.

"Akoa, Marina!" called Professor McGonagall.

Marina sat on the stool, and put the hat on her head.

"I sense a brave heart, a strong-willed mind, and a burning desire to protect her friends. Without a doubt…GRYFFINDOR!" shouted the hat.

"Wayne, Terry!" called Professor McGonagall.

*Well, no turning back now, * I thought with a small shrug, setting the hat on my head.

*Well hello there, Mr. Wayne. If I am to sort you, I will need you to take down the protective wall you've set up. *

*What if I don't want to? * I shot back. *My head isn't a nice place to be.*

*Then I can't sort you. I've already found out your secret through Dumbledore. Your secret is safe with me. *

Slag it, this hat was getting on my nerves. For the sake of the mission though, I took down my mental barrier.

The hat screamed.

"GRYFFINDOR! GRYFFINDOR! GET ME OFF THIS HEAD NOW!"

I suppose that means I have to go sit down at the Gryffindor table. Shouldn't be that hard to find. I'm gonna take a guess and say it's the table that started cheering.

I grinned. I told him my head wasn't a nice place to be; that stupid hat just had to see for himself.

AFTER THE MEAL

Harry

"You coming?" I asked Terry, Marina, and Kai. "We have to go up to the dorms for bed now. Follow me and I'll show you where it is."

Terry shook his head. "We have to talk to Dumbledore. We'll join you later."

"Thank you anyway," added Marina with a small smile.

"What do you have to talk to Dumbledore about?" asked Ginny.

Terry smiled mysteriously. "That's our business. Go on, we'll catch up later."

Ginny and I exchanged looks.

"Alright then," I told them. "See you in a bit."

Marina

"It's probably best if we split up for now," said Terry. "I'll talk to Dumbledore. Kai, you follow Harry and the others up to the dorms."

Kai turned around and strode out of the Entrance hall immediately.

"Marina, you give Kal the mission report. Don't worry about the enchantments on the school; Dumbledore says he's modified it so that all of our equipment works," ordered Terry.

"Roger," I said cheerfully. I wandered off to find a secluded place to contact Kal. Deciding on an empty classroom on the second floor, I dug out my communicator and turned it on.

"This is Aquagirl to Watchtower," I said. The hologram of Kal-El, otherwise known as Clark Kent, or Superman, appeared on the face of my communicator.

"Aquagirl," said Superman with a nod. "What do you have to report so far?"

"The cult that we've been assigned to protect the school from appears to have an undercover agent working in the school," I informed him. "He's a student, the same age as Harry Potter. His job is to find a way for the cult to enter the school, and to assassinate Dumbledore. He seems to be having little or no luck with this; so Batman told us to leave it alone for now, but to keep a close eye on the boy."

Superman nodded. "Very well. Anything else to report?"

I shook my head. "No, we haven't even been here for a full day yet. Be patient Kal, our enemy's plot will reveal itself with time."

Superman sighed, then chuckled. "You're starting to sound like GL. Fine then, keep me posted. Make sure Terry doesn't get into too much trouble."

I sighed. "I don't think that's something I can stop. He's just like Bruce. If he gets into trouble, he figures out how to get out of it."

"True enough," said Superman. "Get some rest Marina. Either Barda or Warhawk will be here to intercept your report in one week's time."

"Where are you going?" I asked, slightly puzzled.

"I'm being called in on a mission for the Pentagon. I'll be back in a week," he answered. Before I could say anything, he turned off his communicator, the hologram disappearing with a flash.

"Oh well," I said aloud to myself, heading upstairs to the Gryffindor Dormitory.

"Diligrout," I told the portrait of the Fat Lady. She swung open and I stepped into the common room. It was every bit as beautiful as I imagined.

"Now change the color scheme to blue and green, and this place would be perfect," I mused. Kai wasn't waiting for me, so I climbed the steps to the Girl's Dormitory. When I opened the door, four girls, including Hermione, were sitting on their beds, in their pajamas, chatting happily.

"Hi Marina!" said Hermione. She turned to the other three girls. "Guys, this is Marina Akoa, she's an exchange student from America."

"We heard," said one of the other girls. "Welcome to the Sixth year Gryffindor Girls Dorm! My name's Pavarti Patil."

"My name's Lavender Brown," said the girl with very frizzy hair.

"Hi! My name's Julia Davidson," said a friendly looking girl with fiery red hair.

I smiled. "It's a pleasure to meet all of you."

When I had changed into my pajamas, Hermione pointed at a bed. "You can have the bed next to mine. We started unpacking for you while you were changing."

"You didn't have to do that," I said quickly, bending over my trunk to finish the job. I know they were trying to be friendly, but there's always the chance they could find something that would blow our cover. Thank Lord Poseidon they only found my textbooks and clothing.

Once I had finished unpacking, the other four insisted that I tell them about myself. If there's one thing I really hate, it's talking about myself.

"Well, I live in Gotham during the year, but I'm from Metropolis and I have a summer house there," I said smoothly. That was all a blatant lie, but I had no choice. We decided that if the three of us were supposed to have the same magical instructor, we had better all be from Gotham.

"Do you have any siblings?" asked Julia.

"No, I'm an only child. But since we've been together for so long, I consider Kai and Terry to be my brothers," I answered.

"Then there's the matter of Terry," said Lavender, smiling slyly at me. "Please tell me he's not your boyfriend, that man is drop dead gorgeous."

I blinked, taken aback with how blunt Lavender was being. "I just told you, Terry's like a brother to me. He's not my boyfriend and he never will be. He's already got a girlfriend back home."

Lavender looked extremely disappointed, but fortunately for her, Pavarti stepped in.

"If you're from Gotham, have you ever seen Batman?" she asked excitedly.

"Yes," I said. This was not a lie. I see Terry practically on a daily basis when on missions. "Gotham has a very high crime rate, so Batman's everywhere. The majority of Gotham's seen him at least once or twice."

"I heard that Batman officially joined the Justice League," said Lavender.

"Really? I always thought he was more of a loner," said Julia.

"He's probably a part time member," I declared. "I mean, the old Batman was, right?"

"That makes sense," said Julia, nodding.

"Alright guys, we can gossip about the Justice League some more in the morning," said Hermione. "It's time for bed."

Everyone obeyed, snuggling down in their sheets after Hermione had turned off the lights.

*Wow, * I thought, staring at the roof of my canopy bed. *Even across the pond in England, the rumors about us aren't that far from the truth. *

Deciding to go for a swim in the lake early tomorrow morning to clear my head, I fell asleep.

Willoffire123: Again, I'm sorry this took so long. What with school and choir, I've been extremely overworked. Plus, I've been watching One Piece in my very slim slot of free time.

Terry: I'm not complaining.

Willoffire123: Good boy. But since I've been watching so much One Piece, the magical gateway of doom that connects this world to the world of One Piece is breaking. I'm giving you, Harry, and anyone else you want to bring along to help, the job of fixing it, and bringing any stray One Piece characters to me. Once the door's fixed, I'll have the power to send them all back to their dimension.

Harry:…what?

Terry: (grabs Harry by the arm and drags him away) just follow me.

Willoffire123: See? He's starting to get how things work here.

Willoffire123: By the way, I would get these chapters done a lot faster if I had a beta reader. Unfortunately, my beta reader for my SE and Harry Potter crossover has most likely never seen Batman Beyond, as it was not on her preference list. So, if you want to beta read, PM me.

Willoffire123: Until next time!
