Hello, everyone! Welcome to my first Gokaiger/Harry Potter crossover story. Yes, I have become a fan of Kaizoku Sentai Gokaiger, my favorite characters would have to be Luka and Ahim for female characters and Marvelous/or Don and Joe for male characters. But I still have a lot to learn about the predecessor to the Power Rangers, which I grew up with originally. But enough of my personal rantings, anyway, honestly I don't remember how or when I came up with this idea, but I had this crazy idea of Gokaigers teaching at Hogwarts after I imagined Marvelous reprimanding Umbridge for interrupting Dumbeldore's speech.

It was almost torture picking what each Gokaiger would do at Hogwarts, luckily I talked with StardustXtreme (who is a bit more knowledgeable about them than I am) about it, Joe will teach swordsmanship and swordplay, Ahim will teach about manner and how to 'gracefully' defend oneself, Don will teach about cooking without the help of the house-elves, Gai will teach about the history of the Super Sentai with Marvelous showing their powers and abilities and Luka will join Fred and George as pranksters while under the title of 'student teacher' and help her fellow Gokaigers. It was because of Marvelous that it was almost a nightmare due to the fact it was hard to see him teaching a separate subject.

Summary: The Gokaigers receive strange letters telling them to teach at a school called Hogwarts in protect a student named Harry Potter and Navi predicts that they will meet three teenagers who will teach them about the Greater Magic of the Ranger Keys outside of Japan. So they head for England and are made teachers by Albus Dumbledore as well as meeting their future students. However, when they meet the likes of Dolores Umbridge, the new Defense Against the Dark Arts teacher, who uses the powers of the Ministry of Magic to ban any and all kinds of action, the Gokaigers must find a way to uncover the Greater Magic of the Ranger Keys and protect young Harry.

Pairings: Marvelous x Luka, Ahim x Don, (Gai and Joe's are a secret)

Prologue

It was a bright beautiful day in Japan, anchored in the city was the pirate ship, the Gokai Galleon. Within the ship, the crew was doing their usual business. Joe Gibken was doing his usual workouts, Ahim de Famille was helping Don Dogosier and Gai Yuki make dinner, Luka Millfy was setting the table with Ahim's help, waiting for dinner, Captain Marvelous was shooting darts while Navi was sleeping on top of Marvelous' chair. It was mostly quiet, when Don and Gai brought dinner to the table, there was a tapping at one of the windows. The crew looked around and Luka noticed a owl by one of the windows, each of the crew members looked at each other with a curious look.

"What is a owl doing here?" Ahim asked, curious as she looked at the gray barn owl as it tried to get into the ship. Don said, "Maybe it's lost or something." He got up to the deck and did a owl's cry to get the owl's attention as the rest of the crew watched it disappear from the window, flying upward and out of sight. The Gokaigers waited for Don to return to start the meal. Don returned with six letters and a very confused look on his face. Luka answered as he walked to the table, "What's wrong, Doc?"

Don didn't answer and handed out the letters to each crew member, then sat down. Each of the crew looked at each other and looked at the letters handed to them. Looking at his letter, Marvelous spoke to Navi, who just woke up, "Oi, Bird, make a prediction." "Don't call me 'Bird'!" Navi shouted in her girly voice before she flew around around the room with a shout, "Lets navigate for treasure!" She flew around until she hit her head on the ceiling. Navi spoke while in her daze, "Out, out of Japan we go! To the east we fly, meet three youths to learn the magic of the Keys! Another strange prediction..." After that, Navi fell to the ground, unconscious.

Confused, the Gokaigers looked at each other, then at the letters they had in their hands. The front of each letter was written in the same style, stating each Gokaiger was in the Galleon. Marvelous wondered if this had anything with Navi's strange prediction and the looks on the faces of his crew was the same. "Should we read them, Marvelous?" Joe asked, looking at his captain as did the other crew members. Looking at them, Marvelous smiled, tapping the tip to his lip and said, "Yes, I think we should read them. See what this is all about and why they were sent to us."

Almost all at once, the Gokaigers opened the letters and read the contents. Gai looked at Marvelous and asked, "Would you read your letter first, Marvelous? I think this may have to do with Navi's prediction, just by the contents of my letter that I've read so far." "Maybe just part of it, but Ahim and I agree." Luka said, after reading her letter with Ahim's letter, Don and Joe also agreed. Marvelous nodded as Navi woke up and sat on his chair as he cleared his throat and read his letter.

HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY

Headmaster: ALBUS DUMBLEDORE

(Order of Merlin, First Class, Grand Sorc., Chf. Warlock,

Supreme Mugwump, International Confed. of Wizards)

Dear Captain Marvelous,

I am pleased to say that you and your crew have to be chosen by Headmaster Dumbledore to teach at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a map to direct your ship to England so we may discuss what classes you and your crew will be teaching.

Minerva McGonagall

Minerva McGonagall

Deputy Headmistress

P.S. We would also like to discuss with you about attending the disciplinary trial of Mr. Harry Potter, one of the students you'll be teaching.

There was a moment of quiet as Marvelous pulled out a map from the evenlope and read it, he thought for a moment and said, "Lets eat first, then go and meet these strange individuals." Nodding in agreement, the Gokaigers ate the wonderfully made dinner, then went to their posts on the Galleon. Luka went up to the crow's nest while Joe and Ahim stayed on the deck, Don and Gai were inside the ship and at the control panel, managing the radar with Navi, and Marvelous was at the steering wheel. Lifting the anchors, the Galleon took off to England.

It took two and a half days to get to England, during that time, Ahim joined Luka in the crow's nest while Joe stayed on the deck and the other male Gokaigers and Navi stayed inside the ship. None of the Gokaigers seemed to know what they were looking to idenifiy the strange people when there was a suddenly firework in the sky. Immediately Marvelous steered the ship in the direction of the firework and anchored, then went to the ground to meet the two most unusual people they have met. One was a elderly old man with a very long white bread and long violet and light blue robes, resting on his nose was a pair of half-moon glasses, beside him was a woman with black hair in a bun and wearing emerald green and black robes. Marvelous and the other Gokaigers could only guess that they were the people wrote and sent the letters to them.

First, the elderly man said to the woman in a strange language that only Gai could really make some of what they were saying, then the woman handed each of the Gokaigers some kind of necklace which she motioned the action of putting it on and tucking it inside their clothes. Otherwise confused, the Gokaigers followed the action, after seeing that the necklaces were tucked away, the elderly man smiled and said, "So you must be the great space pirates I've heard of from a dear old friend of mine. I am Albus Dumbledore and this is Minerva McGonagall."

"Nice to meet you, what is this about a disciplinary trial you wanted to discuss?" Marvelous said, getting straight to the point as quickly as possible and ignoring the fact that he was suddenly able to understand these two. Dumbledore smiled and said, "On August 2nd, Harry Potter and his cousin, Dudley Dursley, were attacked by a pair of Dementors, creatures that feeds on positive thoughts, feelings, and memories. Mr. Potter is being accused for using underage magic. I will be attending the trial as a witness, may I ask you all to attend as defendants?" "But we barely know the kid, how can we act as defendants for this supposed trial?" Luka protested.

Seeming to understand, Dumbledore nodded and said, "Of course, the trial isn't for awhile. So I would like you all to head for Number Twelve, Grimmauld Place to meet Mr. Potter and some of your other students and get accquiated with them while waiting for the date of the trial." After being given directions to the chosen destination, Dumbledore than began to speak with the Gokaigers about teaching at Hogwarts. During the two and half hours, it was decided that Gai would teach about the history of the Super Sentai and Marvelous would help him by using the Ranger Keys, Joe would teach swordmanship and swordplay (though Dumbledore and McGonagall discarded the idea of another Dueling club after the one made by Lockhart), Don would teach about cooking without the help of house elves, Ahim would teach the students about manners while Luka would help with their classes anyway she could and attend the classes as a student teacher.

Afterwards, the Gokaigers returned to their ship and headed for Grimmauld Place. Of course, the time it took to get Grimmauld Place was a lot shorter than it took to get England, about five hours. The Gokaigers reached Grimmauld Place but noticed that there was no number twelve between numbers eleven and thirteen. Marvelous wondered if Dumbledore was messing them about heading to Number Twelve, however he heard a surprised gasp from Ahim and Luka and saw the cause. There, in-between number eleven and thirteen, was number twelve, slowly the Gokaigers approached the door and Marvelous knocked on the door, though Ahim noted there was no doorknob.

Opening the door was a rather skinny boy around the age of fifteen years old, he had very messy raven black hair, semi-hidden by several strands of hair was a lighting bolt shaped scar, hidden behind a pair of rimless round glasses was a pair of emerald green eyes. Confused as the Gokaigers were, the boy asked, "Can I help you?" "Is this Number Twelve, Grimmuald Place, current residence of Harry Potter?" Ahim asked, the boy looked surprised and said, "Sure, come inside and follow me." Guessing by the answer, they were in the right place and followed the boy inside and followed him to the end of the long hallway, Ahim looking at the old looking chandelier and and grim-looking portraits, Luka tightly held her hands as they walked.

Walking up a flight of old stairs, the Gokaigers were led into a room where there was a group of red haired and freckled children standing around and a brown bushy haired girl who suddenly ran over to them, she said, "Harry, who was at the door? Who are those people? I hope it wasn't a-" She suddenly tripped and fell over a broken piece of wood on the floor, but Joe quickly caught her before she hit the ground. Joe's sea blue eyes looked into the girl's surprised cinnamon chocolate brown eyes, he asked calmly, "Are you alright, miss?" "Y-yes, I am thanks to you catching me so quickly." She said, a bit shaken and surprised at her sudden save from the blue Gokaiger. Marvelous thought he saw steam coming out of one of the male red head's ears at seeing this and heard the black haired asked, "Who are you people?"

"The Gokaigers, space pirates who were stationed in Japan. We were looking for the Greater Power of the Ranger Keys when we suddenly got these letters and asked to come here, so we could meet Harry Potter and his friends as well as become his defendants for his trial." Marvelous said, before actually introducing himself and his crew. "I'm Captain Marvelous, GokaiRed. Over there is Joe Gibken, GokaiBlue, next to me is Ahim de Famille and Luka Millfy, GokaiYellow and GokaiPink, on the other side of me is Don 'Doctor' Dogoiser, GokaiGreen, and Gai Yuki, GokaiSilver. And you all are?" "I'm Harry Potter," the black haired boy said, revealing the idenity to the Gokaiger, standing up with Joe's help, the bushy haired girl said, hiding a apparent blush on her face, "Hermione Granger."

The younger male red headed introduced himself as Ron Weasley, while the twins were Fred and George, but they were so similar Luka couldn't tell them apart and lastly there was the only red headed female, Ginny. Marvelous realized that Navi isn't followed, but she was protecting the Galleon and preferred it that way. Harry was wondering why Dumbledore wanted a group of pirates to defend him during his trial and waited until Mrs. Weasley appeared, stating that dinner was ready. Marvelous smiled, and followed the others to the basement kitchen with the Gokaigers behind him. Harry introduced the Gokaigers to a older man who seemed close to him, it was his godfather, Sirius Black, the owner of the house and continued to the basement kitchen.

While the others headed for the kitchen, Marvelous was stopped by Joe and talked with his crew about what they had encountered so far. Though admitting what happened so far was still strange, Marvelous reminded his crew about Navi's prediction and they still needed to figure out what it meant, they continued to the basement kitchen and heard the voice of Mrs. Molly Weasley. "NO, JUST CARRY THEM!" Mrs Weasley shrieked.

The Gokaigers, Harry, Sirius and a shaggy looking man looked round and, within a split second, they had dived away from the table. Fred and George had bewitched a large cauldron of stew, an iron flagon of some kind of drink and a heavy wooden breadboard, complete with knife, to hurtle through the air towards them. The stew skidded the length of the table and came to a halt just before the end, leaving a long black burn on the wooden surface; the flagon of the strange drink fell with a crash, spilling its contents everywhere; the bread knife slipped off the board and landed, point down and quivering ominously, exactly where Sirius's right hand had been seconds before.

"FOR HEAVEN'S SAKE!" screamed Mrs Weasley. "THERE WAS NO NEED - I'VE HAD ENOUGH OF THIS - JUST BECAUSE YOU'RE ALLOWED TO USE MAGIC NOW, YOU DON'T HAVE TO WHIP YOUR WANDS OUT FOR EVERY TINY LITTLE THING!" "We were just trying to save a bit of time!", said Fred, hurrying forward to wrench the bread knife out of the table. "Sorry, Sirius, mate - didn't mean to -" Harry and Sirius were both laughing; the shaggy haired man, who had toppled backwards off his chair, was swearing as he got to his feet; a large ginger colored cat had given an angry hiss and shot off under the dresser, from where his large yellow eyes glowed in the darkness. Luka was calming down Ahim from her shock of what happened, while Don was frozen stiff, Gai was visibly shaking from the action, Joe and Marvelous were unfazed by the action and laughing with Harry and Sirius though they were confused by what just happened.

"Boys," a man said, looking like Mrs. Weasley and her children as they found out it was Mr. Weasley, lifting the stew back into the middle of the table, "your mother's right, you're supposed to show a sense of responsibility now you've come of age -" "None of your brothers caused this sort of trouble!" Mrs Weasley raged at the twins as she slammed a fresh flagon of the drink on the table, and spilling almost as much again. "Bill didn't feel the need to Apparate every few feet! Charlie didn't charm everything he met! Percy -" She stopped dead, catching her breath with a frightened look at her husband, whose expression was suddenly wooden.

Marvelous and the Gokaigers wondered who this Percy and what kind of relationship he had with the Weasleys, each wondering what kind of meal they were going to have as Ahim saw a adult version of Fred, George, and Ron appear and learned that was Bill, the oldest of the Weasley children. "Let's eat," said Bill quickly. "It looks wonderful, Molly," a gentle looking amber haired man said, ladling stew on to a plate toward her and handing it across the table. Harry told the Gokaigers that was Remus Lupin.

For a few minutes there was silence but for the chink of plates and cutlery and the scraping of chairs as everyone settled down to their food. Then Mrs Weasley turned to Marvelous, she asked curiously, "Who are you lot?" "We're pirates, the Gokaigers," Marvelous said. "We were asked by this man, Dumbledore, to meet and get to know Harry before becoming defendants for his trial. Our navigator made a prediction about meeting three youths to teach us about something important here in England, but we still need to figure what it means." While they were confused by what Marvelous said, most of the people were wondering the same thing Harry was pondering earlier, why would Dumbledore ask pirates to become defendants for Harry's trial, though Mrs. Weasley was pleased at the idea of them getting to know Harry before that time.

Soon after, everyone went about their own business as they ate dinner. Ahim and Luka complemented on the stew being on par with the food prepared by Don and Gai, which Don blushed with a soft 'thank you'. Hermione would glance at Joe every once in awhile and looked away when he would look her way, Marvelous simply ate due to the fact that he was majorly hungry and enjoyed the food, slightly listening in on conversations that he wasn't supposed to listened to or even know about, like a real pirate, sticking his nose in places he shouldn't and not caring about it. After dinner, Marvelous noticed something at the dinner table. As he laid down his spoon there was a lull in the general conversation: Mr. Weasley was leaning back in his chair, looking replete and relaxed; a girl who was able to change her appearance was yawning widely, her nose now back to normal; and Ginny, who had lured the cat out from under the dresser, was sitting cross-legged on the floor, rolling corks from her drink for him to chase.

"Nearly time for bed, I think," said Mrs Weasley with a yawn. "Not just yet, Molly," said Sirius, pushing away his empty plate and turning to look at Harry. "You know, I'm surprised at you. I thought the first thing you'd do when you got here would be to start asking questions about Voldemort." The atmosphere in the room changed with the rapidity Harry associated with the arrival of Dementors. Where seconds before it had been sleepily relaxed, it was now alert, even tense. A frisson had gone around the table at the mention of Voldemort's name. Lupin, who had been about to take a sip of wine, lowered his goblet slowly, looking wary. "I did!" said Harry indignantly. "I asked Ron and Hermione but they said we're not allowed in the Order, so - " "And they're quite right,' said Mrs Weasley. 'You're too young." She was sitting bolt upright in her chair, her fists clenched an its arms, every trace of drowsiness gone. The Gokaigers wondered what happened before they had arrived for this to occur.

"Since when did someone have to be in the Order of the Phoenix to ask questions?" asked Sirius. "Harry's been trapped in that Muggle house for a month. He's got the right to know what's been happen-" "Hang on!" interrupted George loudly. "How come Harry gets his questions answered?" said Fred angrily. "We've been trying to get stuff out of you for a month and you haven't told us a single stinking thing!' said George. "'You're too young, you're not in the Order,'"said Fred, in a high-pitched voice that sounded uncannily like his mother's. "Harry's not even of age!" "It's not my fault you haven't been told what the Order's doing," said Sirius calmly, "that's your parents' decision. Harry, on the other hand -"

"It's not down to you to decide what's good for Harry!" said Mrs Weasley sharply. The expression on her normally kind face looked dangerous. "You haven't forgotten what Dumbledore said, I suppose?" "Which bit?" Sirius asked politely, but with the air of a man readying himself for a fight. "The bit about not telling Harry more than he needs to know," said Mrs Weasley, placing a heavy emphasis on the last three words. Ron, Hermione, Fred and Georges heads swivelled from Sirius to Mrs Weasley as though they were following a tennis rally. Ginny was kneeling amid a pile of abandoned corks, watching the conversation with her mouth slightly open. Lupin's eyes were fixed on Sirius.

"I don't intend to tell him more than he needs to know, Molly," said Sirius. "But as he was the one who saw Voldemort come back" (for some odd reason, there was a collective shudder around the table at the name with the Gokaigers looking at each other confused) "he has more right than most to - " "He's not a member of the Order of the Phoenix!" said Mrs Weasley. "He's only fifteen and - " "And he's dealt with as much as most in the Order," said Sirius, "and more than some."

"No one's denying what he's done!" said Mrs Weasley, her voice rising, her fists trembling on the arms of her chair. "But he's still - " "He's not a child!" said Sirius impatiently. "He's not an adult either!" said Mrs Weasley, the colour rising in her cheeks. "He's not James, Sirius!" "I'm perfectly clear who he is, thanks, Molly," said Sirius coldly. "I'm not sure you are!" said Mrs Weasley. "Sometimes, the way you talk about him, it's as though you think you've got your best friend back!"

"What's wrong with that?" said Harry. "What's wrong, Harry, is that you are not your father, however much you might look like him!" said Mrs Weasley, her eyes still boring into Sirius. "You are still at school and adults responsible for you should not forget it!" "Meaning I'm an irresponsible godfather?" demanded Sirius, his voice rising. "Meaning you have been known to act rashly, Sirius, which is why Dumbledore keeps reminding you to stay at home and -"

"We'll leave my instructions from Dumbledore out of this, if you please!" said Sirius loudly. "Arthur!" said Mrs Weasley rounding on her husband. "Arthur, back me up!" Mr Weasley did not speak at once. He took off his glasses and cleaned them slowly on his robes, not looking at his wife. Only when he had replaced them carefully on his nose did he reply. Before he replied, everyone took notice the Gokaigers left the room so they felt the upcoming conversations would be confusing for them.

Splitting up so they could explore more of the place, Joe went to a empty room and looked out the window at the Gokai Galleon which no one outside seemed to notice. He looked at the Galleon for a while when he heard a crack at the door and saw Hermione coming in. When she saw that the room was occupied, she was going to leave but Joe stopped her saying, "You can come in. I don't mind the company." Hermione smiled and nodded, walking up beside him. Looking out the window, she asked, "Is that your ship? It looks amazing. Are you guys really pirates?"

"Yeah, that is our ship and we are pirates, we just don't give that impression to our appearance," Joe said, smiling as well. So the two talked about each others' lives, how they each became a part of their current circle of friends and how they are enjoying their lives now. Before they knew it, it was time for bed and Hermione asked, "See you tomorrow?" "Yeah." Joe said, as he joined the Gokaigers while she headed for the room she shared with Ginny to sleep.

When they were back on the Galleon, most of the Gokaigers fell asleep, Joe remained awake, he was still wondering about Navi's prediction and felt that they had met the three youths they needed to meet but how would they teach them about the magic of the Ranger Key? Pulling out the Blue MagiRanger Key, Joe thought back to the talk he had with Hermione in the house and remembered how happy she looked when he told her about how they used the Keys to help protect the world. Giving a small smile, Joe fell asleep. Meanwhile back in the house, Hermione placed her bed near the window and looked out, staring at the Galleon. She also thought back to the talk she had with Joe and smiled, letting sleep take over as she was unaware of another more sinsister space ship hidden in the sky.


What the Gokaigers were given are necklaces that allows them to understand the English and talk with them in the same language, they needed some way to communicate with their companions and students. Next chapter is the trial and the unofficially meeting with Umbridge. I was seriously doubting on if Gokaigers attending the trial or not, so I decided on them arriving at Grimmuald Place after Harry did and get to know him and the others before the trial. Please, R&R. I would really like it.
