Hogwarts Exchange Students

Rated T for Teen, for slight cursing

Disclaimer: I dont own any characters here; they belong to J.K. Rowling, Akira Toriyama, Yoshihiro Togashi, Eiichiro Oda or Ken Akamatsu. The world, including names for Quidditch teams and most spells, belong to J. K. Rowling, which Ive used for my own convenience, albeit trying to loosely follow the Harry Potter plot.

Harry Potter Crossover with Dragon Ball Z, Yu Yu Hakusho and One Piece, and featuring Magister Negi Magi! Alternate Universe, set in Harrys fourth year.

Characters from all series are tweaked to HPs world, but I will try to maintain them as loyal as possible to their original series counterparts. Their language will be tweaked according to where they are from though, since I didnt want all of them to be from Japan. No need to truly read any of the series here beforehand, except probably Harry Potter, but it helps to know the characters.

Pairings: Hopefully loads! Who knows what will come of this?

Chapter 4: The Dark Mark

Harry didn't understand why people were getting so hysterical, much less what that strange "cloud" in the sky meant. Whatever it was, he was sure that a skull with a serpent coming out of its mouth was no good omen. He also noticed he wasn't the only one completely lost; most younger wizards, foreign ones in particular, were also at a lost. Those older wizards, even the foreign ones, were looking concerned. Those that weren't freaking out were getting their wands out, determined to find out what happened. Vegeta was the first to go into action.

"Trunks, follow me, now" The infamous hit mage called to his son. Locking eyes with his father and realizing how serious the situation was, Trunks handed his broom to one of his teammates in mid-air, and literally flew in the air, following his father's lead to the mark. All around the field, the fans didn't know what was more amazing: that dark mark in the sky returning after over a decade, or the fact that two wizards were flying broom-less to it.

"Dad, what is that thing? Why is everyone freaking out about it?" Having grown up in peace times in the state of Colorado, he had no idea what the wizards in the "Old world" were living through when he was still a baby.

"That is the mark of the Dark Wizard Voldermort, a mark only supposed to surface when he or his followers killed someone" Vegeta's face was stern. He wasn't particularly thrilled about putting his son in whatever danger this could mean, but he wasn't about to trust anyone else with his back.

"Volde- what now?" Trunks hadn't even heard about this wizard. His History of Magic classes focused only on the history of European-descended wizards from the time of the colonies and onward, mostly those on the United States; not what you would call an universal view.

"Voldermort, and don't repeat the name" said Vegeta. "He's an European wizard which I'd hoped was dead by now. He caused a lot of trouble before you were born, and because of stupid international laws we couldn't interfere." Suddenly Vegeta's eyes widened. He didn't see the stupid weak-minded, cheating dark arts users he expected to, the so-called Death Eaters. Instead, he saw the type of wizard he had no experience against: the specialty wizards called Logia, who could literally transform themselves into a particular element. This was one of the hardest and most delicate of dark arts to fight against. Vegeta himself was pretty much unable to.

"Trunks, get Shanks, now" Vegeta spat, as he analyzed the situation. "Tell him its Blackbeard."

"What? But I thought we were going to-?"

"Now, Trunks!" Vegeta glared for a second at his son, and Trunks understood how worried his dad was. He caught a glimpse of the wizards that had made the mark, and they were quite the unusual-looking bunch. They were carrying unusual weapons and no wands at all: they were alternative magic users. Trunks couldn't focus his eyes on who he supposed was the leader of the group: a fat, tanned-skin man with curly black hair and a matching beard. He was hard to distinguish, as he seemed to be shrouded in something smoke-like but not quite smoke, something that just seemed to drain the light around him. It was an ability unlike anything he'd ever seen.

Flying in the direction of the stadium, Trunks noticed quite the mess of people running out of the stadium, and he looked for the familiar face of "Red-haired" Shanks within the crowd.

"Shanks!" he called, flying from above, lifting his head for a bit to push some lavender bangs from his eyes. "Its Blackbeard! We need you in the front line!"

"Gimme a lift, will ya, boy?" Shanks lifted up his lone arm, his lightly tanned skin glistening on the sun. The young man of lavender hair grabbed hold of it, flying him off back into the battle. As he returned to the field of battle, Trunks understood completely why his dad wanted him out of there: Vegeta was being completely overwhelmed by the crew he was fighting, seeming almost unable to even touch his current adversary. You could see the man barely able to stand, yet still he stood proud.

"Dad!" Trunks yelled out, in complete disregard to his own safety. He threw Shanks forward, trying his best to fight the urge to join his dad on the field, and he wasn't surprised to see the veteran auror fall easily on his feet.

From a safe distance, Trunks watched the battle, analyzing every angle. He saw how Shank's presence grew; he could even feel it in his bones. Some of the weaker-willed wizards surrounding them even fainted because of it. He noticed that surrounded by the shroud of darkness the leader had around him (which he supposed was this Blackbeard guy his father was so nervous about) were three muggles, the poor people who rented out this space to the hundreds of wizards at the site.

"Now, now, Teach, I heard you betrayed Whitebeard and left his crew, but I didn't think you'd stoop to doing something this low." Shanks' voice was calm and collected, sounding almost merry in his anger. "And in a crowded place such as this? For shame."

"Why if it isn't the famous Red Haired Shanks" said Blackbeard with a sneer. "You think you're something else, don't ya? Coming to fight all of us alone?"

An invisible projectile just skimmed Blackbeard, leaving a small cut on his face. This immediately shut him up, his eyes on the lookout for his attacker. Trunks could see the attacker, a curly-haired blonde man of tanned skin he recognized as part of Shank's Auror crew, Yassop if he remembered correctly. He also recognized the others running with him as part of Shanks crew, including his right-hand man and swordsman, whose name always escaped him. Blackbeard and his men noticed them too, looking at each other. They knew they'd overstayed their welcome.

Without a second thought, Blackbeard and all the ridiculous creatures of his crew were enshrouded in darkness, just long enough so they were able to escape. Needless to say, remembering the existence of the muggles they were tormenting was not their highest priority.

"Wait, how the blazes did your man give him a warning shot?" yelled Vegeta in indignation. "Weren't logia unhittable? Why the hell did even he give a warning shot instead of shooting him between the eyes?"

"Ah, always the violent one, aren't you Vegeta?" said Shanks, patting the shorter man's back. "We're lucky to have you on our side, I sure wouldn't like fighting against you." Shanks began to check on the forgotten muggles, checking their vitals and responses. "These guys are alive huh? They don't seem to have any damage on them save for the shock. We need a crew of obliviators over here!"

Vegeta was getting annoyed at Shank's ability to ignore him and demean him at the same time. It was like this every time they met. "Shanks! Blackbeard?" he emphasized.

"Oh yeah! Teach!" said Shanks, grinning as if he had really forgotten the subject. "He's a special logia, who can null other people's abilities, but he can't really turn into darkness. Your punches would have done nicely against him, instead of your blasts."

"Son of a bitch" Vegeta cursed under his breath. "Your magic rules are absurd, did you know that?"

"Yours make no better sense to me, so don't sweat it," Shanks said with a smile. "Brave kid you got there. Is he joining Albus's school this year for the tournament?"

"Damn right he is, he'll be the competitor," Vegeta gloated proudly. "There's no better than him in the whole United States! He'll be winning the tournament."

"Maybe, but the Puerto Rican kids have potential aplenty" said Shanks, unsuccessfully trying to hold back a smile.

"Don't tell me you actually believe that Luffy kid of yours can beat my son?" Vegeta found that idea quite ridiculous. "Chances are he wont even be chosen!"

"We'll see, we'll see," said Shanks, shaking it off, and turning his gaze to the young Briefs who still watched them from afar. "Vegeta's boy, do me a favor will ya, boy?"

"Anything, sir! How can I be of help?" Trunks answered enthusiastically, taking the chance to get closer.

"Keep an eye on Luffy for me during this year, will ya?" said Shanks, putting a gentle hand over the young man's head. "He'll be joining you in Hogwarts."

A/N: The plot thickens! Don't you worry, Harry Potter Loyals, Voldermort will be around! He'll just have help aplenty now! And as you can see, there are also many ways on which you can practice magic! I hope its to your liking! Read and please REVIEW!
