Harry Potter and the Yamato
Summary: The space battleship Yamato gets thrown back in time to early 1990s. In exchange of having their ship repaired to go home, they must help a strange society of wizards and witches defeat Voldemort in an upcoming war.
The Yamato sored thru space, completing its mission. Gather enough plasma and direct energy to build an armory of the Type 55 Storm rifle. Firing plasma with a 600 RPM rate of fire, it was lethal in close to mid-range combat.
"So we got all the plasma and stuff we need?" Kodai asked.
"We got it all." Shima said, sitting at his consol.
"Get us to earth." Kodai ordered.
Activating its wave motion engine, the Yamato entered its warp field, and road the tachyon beams to earth. As luck would have it, a problem occurred.
"Captain, we're seeing an unknown head towards us. From behind." Aihara said, looking on his radar screen.
"We're in a warp field. What is it?" Kodai asked.
"It's…" Aihara said, but didn't finish.
The unknown hit the Yamato, sending waves of cascading energy across the warship.
"Engineering, what's going on?" Kodai asked.
"The wave motion engine is taking a beating!" Tokugawa replied, seeing energy spikes cascade across the large alien device. He shut the engine off, which turned off power throughout the entire ship.
Alarms screamed across the ship, as the Yamato struggled to stay in the warp field. Unfortunately, with the wave motion engine offline, they were abruptly kicked out of the field. The ship fell towards a planet, very fast.
"Shit! All hands, brace for impact! Put all power to the hull armor and shields!" Kodai ordered, struggling against the crushing g-forces.
"Sir?" Sanada asked.
"Assuming we survive the crash, we'll need to be in one piece." Kodai replied.
The battleship fell into a body of water, submerging at first, then floating back up to the surface.
"All hands, report." Kodai said, getting up and holding a bloody head.
"Ship's still intact. The engine's off line. We're not leaving orbit, let alone warping." Sanada said, running a diagnostic across the ship.
"Alright. Get the storm rifle's running. If we get attacked, I want to defend myself." Kodai said, then headed towards the armory.
Hogwarts. School of Witchcraft and Wizardry
A dreary night hung over the school. Albus Dumbledore, headmaster of the school, looked at the sky, with a weary look.
"Albus, you okay?" Minerva McGonagall asked.
"Minerva, I'm not okay. Let me show you something." Dumbledore said, heading to his room.
The two professors arrived at Dumbledore's room, and looked into the Pensive. But Dumbledore grabbed a small cup, filled with some tea leaves. He dropped the cup into the pensive, and the two looked into the pensive.
The two saw a massive warship, engulfed in flame. It was heavily armed with many weapons, and fought against hundreds of similar ships, destroying them by the scores. They then saw the same ship, parked right next to the castle.
"Albus, what does this mean?" Minerva asked.
"I don't know. But the ministry of magic is being a dick. They're refusing the fact that Voldemort is back, and probably has an army. Lets keep this to ourselves. Don't let anyone know." Dumbledore ordered.
"I'll keep shut about it." Minerva said.
As she left, Dumbledore looked into the pensive one more time. He saw the same warship, in a strange dimension, facing a much larger, and more menacing, spaceship. To his surprise, the bigger spaceship was quickly destroyed.
"What kind of ship is that?" Dumbledore asked, as he left.
Space Battleship Yamato
"We have the weapons up and running. Fighters are ready to launch at your command." Sanada said.
"Alright. Launch two fighters. Have them head into space first. Take notice of the stars, the planet, and the system we're in. That should help us." Kodai said.
The two fighters lifted from the Yamato, and headed into space.
"I don't see anything." Akira replied.
"Me neither. Look at the star positions. That should tell us where we are." Saigo said.
The fighters took extensive scans of the stars, and noticed that the planet was the third from the sun. Looking at the surface, they saw the continents of Europe, Africa, and Asia.
"Are you kidding me!?" Saigo asks, completely baffled.
"We better report this to Yamato." Akira said, gunning it back to earth. Literally.
"What?" Kodai asked.
"Yeah. We're on Earth." Akira said.
Sighing a breath of relief, Kodai continued his orders.
"Good. Hail command. Tell them we're in need of repairs. We're in the Atlantic ocean." Kodai said.
"Captain, we took scans of the stars, and even the dates have been changed. We've traveled back in time, to August 27th 1995." Saigo said.
"That's impossible." Kodai replied.
But despite his protests, Kodai sent an SOS signal on the channels, only for no replies, because no country on earth at the time had the same communication technology as the Yamato. The captain tried every frequency. They event sent a message in Morse code. The reply was this.
Hey asshole. The Yamato was destroyed in 1945. And we don't have a captain Kodai in our ranks. Sod off.
Similar replies came in over the next few hours. For the moment, they were on their own.
"Alright. We need a place to put in. Head towards Scotland. Have the fighters scour the area. We might get lucky and find a hiding spot." Kodai said.
The two fighters headed towards Northern Scotland. They found nothing, except a large and old castle. There was a good sized fjord near the castle. After taking a few pictures, they headed back to the Yamato.
Hogwarts
The sonic booms caught the attention of the few teachers at the school.
"What is that?" Snape asked, as he and a few others saw the two mysterious fighter jets.
"No idea. Probably muggle planes." Flitwick said.
Albus wasn't that concerned. He knew that any muggles getting close to it, would only see the school as a dilapidated castle. But was exactly what Kodai was looking for. A place to hide so he could repair his ship.
Yamato
"Captain, we've spotted an old castle in Northern Scotland." Akira said.
"How does that help us?" Kodai replied.
"There's a fjord next to it. It's big enough to hold the Yamato. No-one will be looking for us." Akira continued.
"Okay. Get home, and we'll set course for Northern Scotland. You have the coordinate for the fjord?" Kodai asked.
"Sending them now." Akira said.
The battleship headed towards the fjord, and to Hogwarts.
