A/N: Sorry about the long wait. I ran into the brick wall known as writer's block. Plus I got a little too caught up in some of my chats.

SS2 Megami-sama- I doubt there will be any serious romance; though I might put him through one with a saiyan. Of course it would make more sense to make Gohan 13 instead of 15, that's why I didn't do it. Though I don't recall specifically saying that he was 15; just that he looked it.

Luna's Meow- Once again, something I know nothing about.

Disturbed One- Shaman King and Naruto? And I'm supposed to be able to type about those... how? Interesting YYH idea; I like it. Could you tell me what the opponents in that round were like?

Escudo-blade- I'll see what I can do with those.

Riye Link/Reue- Meh, he already knows those. Actually that might work because I gave Gohan the ability to materialize food with his mind, like how Piccolo makes clothes.

Chapter 4

As soon as Gohan stepped outside, he had to go over to the first year Slytherins to begin the lessons. He walked over and was immediately approached by his friend, Draco, and two friends he had obviously made.

"Hey Gohan," Malfoy said. Gohan nodded in response. "These are my two friends, Crabbe and Goyle." Gohan realized that they looked pretty mean and were thickset, pretty much like bodyguards. He figured that they probably weren't very smart, though, since he seemed to be the only person capable of being smart and strong at the same time.

He looked each of them in the eyes and could see that inwardly, they both flinched. Gohan allowed a smirk to cross his face. They obviously remembered that he could easily beat them up. He had "accidentally" walked into the Slytherin common room one weekend forgetting to put his robes on. Everyone in the common room saw his muscles and news of how strong he must be spread quickly at Hogwarts. Of course, now he had lots of girls giving him glances whenever possible, mostly Slytherins though since the other girls pretended not to care since he was out of their house, even though he knew that they like him too.

"It's a shame first years aren't allowed on the house Quidditch teams," Malfoy stated. "Father isn't too happy about that. I've been playing for years and father says that I have more than enough skill and am better than any seventh year on this team. I should have these two beat some people up so that I'd be allowed to play."

Gohan smirked. "Yeah, I haven't beaten anyone else up in a long time either. Too bad it would only get them expelled or something," Gohan said causing Malfoy to snicker.

Gohan allowed his gaze to wander over the first year Gryffindors, as he hadn't actually seen them before. He could tell that just about all of them were trying to avoid his gaze, afraid that he would do something to them. Harry and Ron just smiled and waved while another first year girl looked really nervous about flying. It was the one who had made a big deal about Ron's attempt at turning his rat yellow. Ron had already told him that she was worried because it wasn't a class you could learn about in books.

The flying instructor, Madam Hooch, came out shortly thereafter greeting the class.

"Welcome to your first flying lesson!" she started. "Well? What are you waiting for? Get on the side of a broom, hold your right hand over it, and say 'Up!'"

All the students said it, but only Gohan and Harry got the broom up on the first call. Some people had to just bend over and pick their broom up because it was taking too long.

Madam Hooch then showed them the proper way to grip their brooms while flying. Gohan heard Harry and Ron snickering when she spent a long time correcting Malfoy's grip and telling him that he had been doing it wrong all these years.

"When I blow my whistle, kick hard off from the ground," Madam Hooch instructed. "Rise a few feet and then come straight back down by leaning forward slightly. On my whistle, three, two..."

One of the Gryffindor first years was so nervous that he had kicked off the ground before the whistle touched her lips. The broom was rapidly rising straight up.

"Mr. Longbottom! Mr. Longbottom come back down here!" she shouted.

The other Slytherins were snickering to themselves at the kid's scared face. The kid lost his grip on the broom and he slid sideways off the broom and down towards the ground. With a thud and a crack, he fell to the ground lying flat on his stomach.

Madam Hooch quickly ran over there and started checking up on him.

"Broken wrist. Come on, up you get." She helped him up then turned to the rest of the class. "I'm taking this boy to the hospital wing. All brooms are to stay on the ground or you'll be out of here faster than you can say 'Quidditch'." Madam Hooch then led the kid to the hospital wing.

"Poor Neville," Gohan heard some Gryffindor girls saying.

"HAHAHA," Malfoy laughed. "Did you see that kids face? It was hilarious!" Lots of other Slytherins joined in.

"Hey, look what we've got here," Malfoy said, darting forward and grabbing something off the ground. "It's that remembrall thing Longbottom's grandmother sent him."

"Give it here, Malfoy," Harry called. Malfoy just smiled evilly.

"No. I think I'll leave it somewhere for Longbottom to find it. Perhaps up a tree, or on the roof?"

"Give it here!" Harry yelled. Malfoy just ignored him, mounted his broom, and took off. Harry got ready to go after him and swung his leg over the broom.

"You can't go up there!" the bookworm girl, Hermione, shouted. "We were told not to leave the ground. You'll get us in trouble if you do."

Harry just ignored her and kicked off from the ground. Gohan noticed that flying the broom seemed to be natural to Harry as Harry easily rose up to Malfoy's height.

"Give it here Malfoy or I'll knock you off your broom!" Harry threatened.

"Alright. Catch it if you can!" Malfoy shouted and threw the remembrall high into the air and straight towards the castle.

Harry chased after the remembrall and leaned forward to dive and gripped the broom harder as it accelerated. Harry continued chasing it and caught it two feet off the ground then pulled up hard to land safely. He got off the broom and walked back towards the cheering Gryffindors.

"HARRY POTTER!"

All the cheers stopped and turned to gasps as Professor McGonagall ran out of the castle and to the field.

"How dare you do that- never in all my years at Hogwarts have I seen such an act. Potter, follow me," McGonagall exclaimed.

Professor McGonagall led Harry away, presumably to get expelled. Whispers broke out about him and how people were going to miss him.

"Hey what do you know? Professor Snape was right. Fame isn't everything," Malfoy said. He then faked some tears. "It's so sad to see Potter go... NOT!" The Slytherins broke out into laughter again.

"Alright, alright," Madam Hooch called. "Let's get back to flying now that the boy is taken care of. Is someone missing? I could have sworn there was another person here before."

"Professor McGonagall had to take him for something, Madam Hooch," Ron said before Malfoy could say anything. Madam Hooch nodded in understanding before returning to her teaching duties.

"Alright then, everyone mount your broom. On my whistle, kick off from the ground, hover for a moment, then land by leaning forward. Three, two, one..."

Madam Hooch blew her whistle and all the kids kicked off from the ground. To Gohan, this didn't feel too much different from when he normally flew, except for the broom between his legs. Otherwise, it was pretty much the same as when he used his ki to fly.

Gohan hovered several feet up in the air. He saw that a lot of people were having a hard time doing it and several were too scared about falling off like Neville that they hadn't even kicked off from the ground. Gohan leaned forward slightly and felt himself descending to the ground.

"Okay. Now, everyone is to kick off the ground again, but this time, lean forward more to move your broom forward. Everyone spread out!" Madam Hooch instructed.

Gohan kicked off the ground and leaned forward. His broom went zipping forward and he stopped several inches in front of Crabbe. He then turned around and moved back to where he had been. Experimentally, he tilted the broom upwards and found himself moving gaining altitude. He had to come back down, however, once he got high enough that Madam Hooch realized that he wasn't paying attention to the lesson.

"In order to move faster," Madam Hooch said, "You have to lean forward on your broom. The farther forward you lean, the faster you will go."

Gohan tested the theory and lied down flat on his broom. The broom shot forward at a rapid pace. It was a good thing that Gohan had been pointing away from any other students. He dashed back and found Malfoy.

"Hey Malfoy!" Gohan called. "What do you say to a little race?"

"You're on. Don't be surprised when I humiliate you."

Gohan and Malfoy lined up and pointed away from the group. When Goyle called 'go', the two took off towards the wall Harry had just dove at to catch the remembrall. The stopped when they reached it, turned around, and sped back to the rest of the kids. Gohan won since he didn't slow down as much to turn around.

"I win!" Gohan proclaimed. "I thought you were going to beat me, Draco." Malfoy just rolled his eyes at him and flew over to Crabbe and Goyle.

The lesson ended shortly after and everyone returned down to the ground and left for lunch. Everyone was surprised when the saw Harry sitting at the Gryffindor table eating lunch.

"Why are you here, Harry? Aren't you getting expelled?" Ron asked.

"Nope. Professor McGonagall took me to the captain of the Quidditch team. I'm to be the team's seeker since last year's seeker was a seventh year so he left," Harry explained. Just then, Malfoy walked over.

"Well, well. Last meal Potter?" Malfoy asked. Harry ignored the question but did make a comment.

"You seem a lot more confident now that you've got your friends to back you up," he stated.

"I could take you anywhere, anytime, Potter. In fact, why don't I prove it to you? We'll have a wizard's duel tonight at midnight in the trophy room. You don't even know what a wizard's duel is, do you Potter?"

"Of course he does," Ron interjected before Harry could say a thing. "I'm going to be his second, who's yours?" Malfoy looked at his friends then smirked.

"Gohan will be my second. I'll see you tonight." With that said, Malfoy turned around and walked back to their table. Once he was out of hearing range, Harry turned to Ron.

"What's a wizard's duel? And what do you mean by you're my second?"

"Well, a wizard's duel is a fight between two wizards. A second is someone who takes over for you if you die. Don't worry about that though, you and Malfoy will probably only be able to shoot sparks at each other."

"What if I wave my wand and nothing happens?" Harry inquired.

"Then just throw your wand aside and punch him in the face."

Gohan turned to look at Malfoy when he heard him snickering about tricking the fools into agreeing with that and how much trouble.

"What the hell are you talking about, Draco?" Gohan asked.

"I was telling Potter, over there, how I could easily beat him so I challenged him to a wizard's duel at midnight tonight, and he accepted. I'm going to go tell Mr. Filch about it and he's going to be in so much trouble." Gohan went into Malfoy's mind to find out what a wizard's duel was. Once he knew, he started snickering.

"Those guys are such fools. They won't know what's wrong until Mr. Filch is already there." Gohan then laughed aloud.

Since they had the rest of the day off, Gohan decided to practice his magic. He was learning to put his ki into his wand so that he could use his energy attacks and make it look like they were coming from the wand. Gohan was also starting to figure out how to do the magic without his wand, but he made sure no one else was near when he practiced that.

At around midnight, Gohan felt Harry and Ron, along with two other energies, heading from the Gryffindor common room towards the trophy room. Gohan also felt Mr. Filch heading towards the trophy room, Malfoy had obviously told him as planned. He smirked then returned to his meditation, which he was finally able to do while lying down.

Since yesterday was Friday, most of the other students didn't wake up until at least ten o'clock. Gohan was up and training as usual at three in the morning. After a quick breakfast, Gohan met up with the Weasley twins as long as their friend, Lee Jordan, to plot some pranks to pull on this upcoming Halloween.

"We've got some wicked ideas to pull this year," George explained. "We just need some better ideas to finish off the plan and really scare all the kids here. Any suggestions?"

"Actually, I do have one," Gohan said. "I was doing some reading about the history of Hogwarts and found out about a place called the Chamber of Secrets. Supposedly there was this really dangerous creature that came out of there almost fifty years ago that killed a girl. We could tell people that the monster has been unleashed upon the school."

"That's bloody brilliant!" Fred exclaimed. "When you think of pranks to pull, Gohan, you scare the crap out of them. Too bad ideas don't come to you more frequently. That will definitely work. What do you too think?"

"Genius. Pure genius my man," Lee said.

"This is going to be one Halloween they're all going to remember," George said. "Think they'll finally expel us for that one?"

"Probably not," Gohan stated. "Although they don't show it, most of them probably find your pranks amusing. And what harm can scaring people on Halloween be?"

"Yeah, he's got a good point there. There really isn't a rule against scaring kids badly," Lee pointed out.

"Alright then. Oh, here Gohan, some more pranks to leave about." George handed Gohan a box, which held some pranks. Although Gohan wasn't in Gryffindor, the pranksters found that it was even better because now they could prank the Slytherins.

Gohan left them and went to the library to do some of his homework. He pulled out his transfiguration book and started the lesson. Gohan had figured that he might as well study year two on his own so he spent a couple hours a weekend studying it and all other year two books.

Harry and Ron came into the library soon after and sat down across from Gohan. As usual, Gohan helped them with their homework while working on his. Gohan mostly helped them with potions, as Snape seemed to favor Gohan. Being as such, Gohan knew some ways to make your grade better by wording it differently.

"Hey Gohan, can you help me with this defense against the dark arts essay?" a third year Slytherin girl, Sarah, asked.

"Sure. What's the problem?"

Gohan spent the rest of the afternoon helping kids with their homework, though mostly doing his own. It was mostly Slytherin girls needing help though, or claiming to just to be near him.

Gohan went to the common room after dinner that night and wrote his letter to Mrs. Weasley. She had said that she would send him mail so that he would be getting mail from someone, not that he really cared. Unfortunately, she had a nasty habit of taking things too far. For example, if he said that he helped a girl with homework, she would say something like 'Oh, sounds like you have a crush on her' or something of the sort. Thus he had to frequently hide his letters and not read them until he was alone before his morning training sessions.

Halloween approached quickly for the Hogwarts' students and decorations were being put up for the annual Halloween feast. Gohan overheard that Ron had apparently upset Hermione with one of his smart-ass comments. It seemed that she hadn't shown up for any lessons after that. He sensed her out and realized that she probably wouldn't be joining them for dinner, either. Oh well, more food for him.

When Gohan made it to the Great Hall, he found thousands of bats flying around and pumpkins floating where the candles usually were. He sat down and enjoyed the pumpkin pie and other various Halloween treats. All attention was drawn to the doors as Professor Quirrell came sprinting into the hall with his turban askew and his face filled with terror.

"TROLL! IN THE DUNGEONS! Though you ought to know," he said before fainting and falling to the ground.

That started an immediate panic among all the students except Gohan, who just continued eating as though nothing was wrong, since there was no danger as far as he was concerned. Silence wasn't brought about until Dumbledore's thundering voice took over the students.

"SILENCE!!!!" he bellowed. "Now, if everyone would please remain calm. Prefects, lead your houses back to the dormitories immediately. All professors, please follow me down to the dungeons."

Gohan had started to follow the Slytherin prefect until he realized that Harry and Ron were ditching away. Figuring it would probably be more interesting to be with them than some panicking Slytherins, Gohan took off after the two. He fazed out and appeared along the ceiling above the two. For safety, he sent a clone of himself back with the Slytherins so he wouldn't get in trouble.

Gohan heard some rapid footsteps coming, and saw Professor Snape rushing down the corridor heading to the third floor, as he heard Harry confirm. His nose was then assaulted by a hideous stench that almost made him faint. Gohan also heard the shuffling of gigantic feet and the dragging of something heavy.

Looking down the corridor, Gohan caught a glimpse of the troll. It was over twelve feet tall and had gray skin. It had a lumpy body and was bald. It had very thick legs and was holding a humongous wooden club. The club was dragging due to the length of the troll's arms. Gohan could tell that Harry and Ron had noticed its presence soon afterwards. Gohan watched as the troll went into a room.

"Hey, the key's in the lock. We could lock it in there," Harry muttered. They started to do it until Gohan dropped down in front of them.

"Hate to ruin your parade, but that's the room Hermione's in. I don't think you came this far to lock her in there with big, tall, and ugly over there," Gohan stated. Harry and Ron were somewhat shocked with how Gohan just dropped down from the ceiling without hurting himself before they realized that that room was, indeed, the girls' bathroom.

The three rushed in there and heard a loud, high-pitched scream. They found Hermione against the wall looking petrified. The troll was walking towards her, swinging his club and knocking the sinks off of the wall. Harry grabbed a metal pipe and threw it against the wall.

The troll, confused by the sound, turned around looking for the source. His eyes spotted Harry and started moving towards him. Ron tried altering his attention by throwing some debris at it, but it didn't even notice it. It did, however, notice the screams Hermione was letting out and turned his attention back to her.

The troll seemed to be going crazy with all the noises. It started swinging its club around trying to stop the annoying sounds. His club smashed down on the sink right next to Hermione and she screamed even louder. Thinking quickly, Gohan pulled his wand out and pointed it at the monster.

"MASENKO HA!!"

The stream of yellow energy flew at the enormous troll and knocked its club out of its hands and into the air. Gohan then rushed over and pulled Hermione out of the corner and near the others. Ron pulled his own wand out and yelled the first spell that came to mind.

"Wingardium Leviosa!"

The club stopped floating in midair above the troll's head. The troll stared up at its club in confusion until it fell down and hit him hard on the head. The troll fell forward, face first, into the ground with the club falling next to him.

Gohan, who heard and felt the approach of the teachers, placed a hand on Hermione and Harry while instructing Ron to hold onto one of them. When they were ready, Gohan used instant transmission and reappeared in the Gryffindor common room.

"What's going on in here?" Professor McGonagall asked as soon as she walked into the bathroom. She, along with the others, saw that the troll was lying face first unconscious on the ground.

"It must have hit itself on the head with its club or something," McGonagall stated. Not having any better explanation, the teachers just accepted it and left the room.

~~~~~~~~~~~~~~~~~~~

"That was bloody brilliant but how did you do that?" Ron asked.

"What was that?" Hermione questioned.

"That? Just something I've learned. Allows for instant teleportation. It requires me to lock onto a person and it will teleport you to him or her. Since everyone here is too busy eating, I figured they wouldn't notice our arrival," Gohan explained.

"Well, I don't know what to say, but, um... thanks for the help," Hermione said shyly.

"No problem," Harry said.

"Um... I'm sorry about what I said earlier, Hermione," Ron said.

Gohan smiled then used instant transmission to go back to his other body and merge back into one body. He then went downstairs and returned to consuming the food that the professors had sent up to the common rooms.

"Can you believe this?" Malfoy stated. "My father's going to be disappointed once he hears about this. How could a troll get into Hogwarts? Trolls are even stupider than Crabbe and Goyle."

It was then that Gohan realized that most of the kids were still scared about the troll, the younger kids and girls showing it while the guys pretended to not be scared; talking about how they could defeat the troll to anyone that could listen, mainly their girlfriends or girls they had crushes on, to try and make them feel safer. He debated with himself whether to tell them that the troll had been taken care of or not, but decided against it when he realized that he would have to come up with a reason as to how he had come about this information.

"Maybe someone set it loose in the castle," Gohan suggested. He had sensed Professors Snape and Quirrell's energies heading towards the third floor corridor where he had sensed something reminding him of a dog. Gohan reasoned that one of them might have wanted a distraction to get there without being questioned by others.

The common room quieted down as people considered the possibility of someone actually doing that. It seemed to be the most sense so people started wondering why a troll would be set loose in the castle.

"Maybe it has something to do with the reason that we aren't allowed to go to the third floor corridor?" one of the fifth years offered. "Normally, Professor Dumbledore offers us a reason as to why a place is forbidden, but he didn't do that this time."

"Yeah, but what could Dumbledore be keeping there that's so important?" another Slytherin questioned.

*************************************************

Yay! Another chapter has been completed. I should be back to my normal updating schedule next week. Sorry about getting my schedule off whack, I spent the night at a friend's house so I missed updating last weekend.
