Okay, this is something I've been thinking of writing a long time now

I have to admit that I forgot about it, but now during the February break it came back to me

It's an YGO and Martin Mystery crossover

This will be a kinda short fic, about five to seven chapters.

I hope you'll like it.

BTW It might seem more of a MM fic, but it's an YGO fic

Disclaimer: I do not owe YuGiOh! or Martin Mystery, I only owe the idea of this fic and my OC

Pairing: YamixYugi mostly, might be more

Chapter 1

Martin Mystery, his stepsister Diana Lombart, Java the caveman and the alien in disguise Billy sat outside Torrington Academy enjoying the spring and the sun. Then a beeping sound could be heard. Martin looked at his watch, or rather U-Watch. Searching for a portal to the Center. They stepped through it. A computer scanned their eyes and identified them.

"I wonder what M.O.M, want's this time?" Diana said.

"Maybe there's another slime alien or maybe a warlock" Martin said excited. Diana rolled her eyes. They stepped into an elevator and soon they stood in M.O.M.'s office. M.O.M. herself, was standing behind her desk, something looking like a small computer in front of her.

"Welcome agents, I want you to investigate some very unusual paranormal activity in Domino City. There's been reported that student's suddenly has disappeared" she said.

"What do you mean 'disappeared'?" Diana asked. "Like running away?"

"No, I mean completely. They've just vanished into thin air, even in the middle of the day. There's been paranormal activities there some time now, but no one's ever disappeared 'til now" Martin was sneaking closer to the small 'computer' on M.O.M.'s desk.

"What's this?" he asked.

"That's a new translator, it translates everything you say into over 5000 languages" she replied, before turning her attention back to the others.

"How long has this activity been there?" Diana asked.

"About 2-3 years ago there's almost none, but then it suddenly exploded" M.O.M. replied.

"Then how come you didn't look it up then?" Diana asked again. This time Billy relied.

"We had no reason to"

M.O.M. opened a portal to Domino Square. Then a small 'boom' could be heard behind them. Everyone turned to see Martin and the small computer, crashed. M.O.M. growled and a vein could be seen in her forehead.

"Martin Mystery!" she yelled

"He he, sorry" he said.

"Just. Go!" she said, through gritted teeth, pointing at the portal, and they did.

"So, where do we start?" Billy asked.

"Well, according to the reports most of the student's disappeared some blocks away from here" Martin replied.

"Where exactly?" Diana asked. Martin looked at the paper.

"At Domino High School, but the most recent one's been around an arcade and some building called Kaiba Corp's duel dome"

"Then why don't we go check out that arcade first?" Diana suggested. " I bet most teenagers go there, so it's a good place to start" They went to the arcade, went inside and started asking some teenagers questions about the disappearances.

"Yes, I know Mischa..."

"Last time I saw her was the night she disappeared"

"Rai disappeared a month ago..."

And so it went on. When they went further inside they saw a small crowd around some people. There are two people playing some kind of card game in the middle. It was a blonde teenage boy, with honey eyes. The other was a platinum blond boy, about the same age as the other, that had a tan and violet eyes. It looked like the tanned boy was wining.

"What are they playing?" Martin asked a girl beside him.

"You don't know? That's Duel Monsters. That's Jounochi Katsuya and Malik Ishtar. Jounochi got in second place in the Duellist Kingdom competition and Malik in Battle City. They're really good, but no one's better then the King of Games" she replied.

"Who?" Billy asked.

"Well, Yugi Mouto of course: He's won every duel he's been in" she replied giggling. "He used to come here a lot, but lately he hasn't been here" that caught their interest.

"Why is that?" Diana asked.

"He never has any time, he must take care of his Grandfather's shop. The poor guy, his Grandfather died a couple of months ago, leaving him alone" she said. Then the others began to cheer. "Oh, it seems Malik won over Jounochi again. Then there'll probably be a duel between him and Bakura tomorrow. They're always doing this, the winner get to go against Yugi" she said before walking away.

"Eh, thanks.." Diana said, blinking.

"Looks like the pup lost again" a voice said.

"Kaiba! Shut it, or I'll beat ya sorry ass!" Jounochi yelled. The tall brunette chuckled.

"I'd like to see you try, pup. I just wanted to ask if any of you know where Atemu is. I've lost Yugi...again..." he said.

"Lost Yuge? What are ya talking about?" Jounochi asked confused.

"He's been sleepwalking a lot lately, so Atemu asked if I could watch him tonight"

"Sorry, Atemu hasn't been here at all tonight" Malik said.

"I see, oh well, I better start looking for him again then" Kaiba said, then turning and left the arcade.

"I neva knew Yuge walked in his sleep" Jounochi said.

"Excuse us" Diana said. Jounochi and Malik turned to look at them.

"I've neva seen ya here before" Jounochi said. Malik's eyes narrowed slightly.

"Eh, yes, we're from the Center. We're investigating the disappearances," Diana said. "Martin! Leave those things alone!" she yelled when she saw him very close to Jou's and Malik's Duel discs.

"Sorry" he said. "So did you know any of the students?"

"No, not really. Two of them bullied our friend Yuge, but otherwise no" Jounochi replied.

"I see, and where's your friend now?" Martin asked.

"We don't know" Malik replied. "At home we think"

"Do you know where the students disappeared around here?" Martin asked.

"I think it was in da alley, behind da arcade. Malik?"

"Yes, I think they said that as well, but I'm not sure. Marik and Bakura know more about that, wait scratch Marik"

"Thank you" Diana said, as Martin dragged her towards the exit. Java and Billy following them. Martin looked desperately after the alley.

"Where is it?" he said to himself. "Do you see..." he was cut of by a scream. They ran towards it, and saw a girl and something attacking her. "Leave her alone!" Martin shouted, running towards it. The thing disappeared with the girl.

"What was that thing?" Diana asked.

"I don't know. I didn't see it clearly. Whatever it was it must've left something" he said, activating his U-Watch.

U-Watch activated. Alpha Googles selected the special glasses appeared and Martin put them on.

"I doubt you'll find anything in this alley" Diana exclaimed.

"You'd better listen to her" a deep, rich voice said from behind them. They turned around to see someone in the shadows.

"Who's there?!" Diana asked, a little frightened. Martin went closer so that the lights from the rims of the Alpha Googles fell onto the person.

The said person smirked, showing fangs. He had very pale, almost white skin; and his eyes were blood red. His hair was tri colored, and he wore almost entirely black clothes. Around his neck was a chocker.

"Who I am? I don't think my name is of your concern, but you may call me Yami" he said. "And by the look I think you're looking for the missing students. You're lucky if you find them, human"

"What are you?" Diana asked. The male smirked.

"I thought it was obvious of what I am" he said chuckling amused.

"He's a vampire" Martin said enthusiastically, almost like a child on Christmas. "It's probably he who's captured those students" the other male just stared, his face emotionless. He shook his head, and turned to leave. "Where do you think you're going?!" Yami looked back at them.

"Home, it doesn't matter what I say or do" he said shrugging. "Besides I need to find my sweet" Then he noticed that Java had sneaked behind him, so that he now blocked the way for him. Yami stood between all of them now, but he looked unfazed by it.

U-Watch activated! X-Rod selected Martin tried to capture Yami with the net, but Yami dodged it, only to be captured by Java. Yami's rather surprised by Java's strength, but then he smirks and elbows him hard in the stomach. Java drops him and falls to his knees. The others try to capture him again. Just as Martin is about to shot the net on Yami again, something pins Diana to the ground. Her surprised scream gets her friends' and brother's attention.

"What the-?" Martin begins. Standing on top of Diana is a small grey and white wolf, growling fiercely. Its eyes are a mix of silver and amethyst. Yami blinks surprised, then he smiles gently, lovingly at it.

"It's a wolf!" Billy exclaimed. Martin gives him a questioning look.

"I've never seen a wolf like that before" then Java suddenly kick the wolf in the ribs. Yami gasps horrified. The wolf limps away from Diana and Yami runs to it.

"My poor baby! Did that man hurt you?" Yami ask worried. He gets a whimper in response. Yami takes it up in his arms. It's starting to get brighter, in the horizon the sun is raising. The little wolf whimpers again, Yami nods and sends Martin and Co a cold glare, before disappearing.

"What just happened?" Billy asked, as he blinks confused.

"Java's shoe hairy" Java said, pointing at the shoe he kicked the wolf with. Martin beamed and dived at it.

"Let's send it to M.O.M. for analysis" he said, and does so. "So where should we go now?"

"Well, the best place to start is at the school all the students went to and look through the student record" Diana replied.

25 minutes later, Domino High

"Thank you so much for letting us go through your records, Mr. Kaji" Diana said as they went out of the office. The Principal had allowed them to go through the computer and see if they could find any connections between the missing students.

"I'm happy to help, I'm relieved that someone's decided to get to the bottom of this. I'm worried for my students" Mr Kaji replied.

"Don't worry, we'll find the missing students" Martin said. Diana went through the records, after 20 minutes she had found every one of the missing students' files.

"Look at this, no one except these tugs Ushio and Goza have a connection"

"Really? What is it?" Billy asked curiously.

"They've been bullying someone named Mouto, Yugi. Does that name sound familiar?"

"Yeah, didn't those teenagers at the arcade talk about him?" Martin asked.

"Yes, we had them expelled in three months and they weren't allowed to be anywhere near Mr. Mouto" Mr. Kaji said. Diana searched for the name and clicked on it when it appeared, and gasped.

"Ehm guys, I think you'd take a look at this" she said. Martin, Java and Billy went behind her to look at the screen.

"He looks just like that vampire!" Billy exclaimed, as they saw a boy with tri-colored hair; quite pale skin; and amethyst eyes, glowing with innocence.

"I can assure you, Yugi's a gentle and kind boy. He never does anything to harm others, he is the one who's being beaten by other students" Mr Kaji said.

"We haven't accused him for anything, we're just a little taken a back" Diana said to their defence. "Martin, what do you think?"

"I think we'd go visit Mr.Mouto. In which classroom is he?"

"Mr.Mouto called in sick today" Mr Kaji replied.

"I see. Do you know where to find him?"

"He lives at the Kame Game Shop. It's not very far from here"

TBC

Oh, this was the first chapter and probably longest

It's about Yami and Yugi, which will make their 'first' appearance in next chapter
