Hey, everyone. This is a fanfic idea I came up with while reading the Percy Jackson books. What if Gohan was mistaken for a demigod and ended up at Camp Half-Blood with Percy, Annabeth, and the rest? Enjoy, and I took my own liberties with Gohan. This takes place in a world in which he did not stop with his training after Cell. I apologize in advance in case this chapter is not the greatest. Openings are rarely good for me. I just want to get the introduction out of the way so I can take the fic in my own direction. Rest assured, the next chapter will be better.

Disclaimer: I've never included these before since I think their pointless, but I don't own any of these characters excepts for my OC characters. If I did, I wouldn't be resorting to this site, would I?

Dodgeball game with giants and saiyans

It was the vacuum of space and Gohan was flying through it, running for his life. He was fleeing from two beings who were flying behind him, laughing hysterically as the demi-saiyan tried to avoid the ki blasts they were firing at him. Next to him were a boy and a girl about his age. One of the pursuers looked like a younger version of Freeza, and the other was a strange shadow-like creature whose appearance changed every time Gohan's emotions changed, with the being's purple mane being present in each form. At one moment, he looked like Radiz. At others, Cell.

"You may try to run from us mortal saiyan, but you can't avoid us forever!"The shadow creature bellowed. "But then again, your kind can never escape my eternal wrath!"

"Yes." The Freeza look-alike said as he materialized in front of Gohan. "Let us kill him before he gets the chance to sire the brat who humiliated us in the future!"

"Not in this timeline, she didn't!" the shadow creature growled as he drew his sword. "But still, say goodbye mortals! Not even a god can survive an attack from this sword!"

"Gwahh!" the three pre-teens shouted as the creature sliced through all of them at once with his sword.

"No!" Gohan shouted as he woke. "It was just a dream? Wow. I've never had one that realistic! Oh boy. I hope it isn't a preview of coming events." Gohan asked himself as he jumped out of bed.

"Gohan!" Chichi shouted. "Time to get up and get ready for your last day of school!"

"Okay, mom!" Gohan responded as he flew out the door, literally, saying goodbye to his mother and his little brother, Goten as he flew by.

"Gohan!" Chichi shouted as the demisaiyan flew by. "Don't forget that we're meeting Tyson and Percy in West City after school!"

"Okay, Mom." Gohan said as he flew off to school, little did he know he would not be seeing his mother again for quite some time, let alone in the afternoon.

It had been one year since the events of the Cell Games. Shortly afterwards, Chichi was looking around for a good school for Gohan to attend when she found a progressive school called Meriwether college prep. "It's so he can get into a good high school." Was her justification for enrolling Gohan in middle school, not that Gohan complained about it. All of the classes were way too easy for him, especially since he already knew most of the material. That was the reason behind why he was in seventh grade, despite the fact that he was eleven not including the year he spent in the Hyperbolic Time Chamber. The best part was that he had two good friends, a highly dyslexic boy with ADHD, Percy Jackson, and a homeless boy who was huge and over six feet, Tyson, whom he noticed on the first day only had one eye. He mentioned the anomaly to Percy on many occasions, but he never seemed to notice, and neither did anyone else. He was adopted into the school as a community service project, but none of the students seemed to see it as such except for himself and Percy.

Gohan spotted Percy below and flew down in front of him. "Morning, Percy."

"Geez, Gohan!" the demigod began. "You've got to tell me how you do that!"

"What? The flying?" Gohan asked. "Or the sneaking up on you?"

"The flying!" Percy shouted. "A normal person shouldn't be able to fly."

"Who said I was normal?" Gohan asked. "I'll teach you how over the summer if you want me to."

"I don't know if I can, Gohan. I have summer camp to go to." Percy responded.

"Oh. In that case, I guess I'll just track you down and train you, anyway." The young demisaiyan chuckled.

"I guess that would work. Besides, I wanted to introduce you to my friends there anyway." Percy said. Ever since he first saw Gohan fly very early in the school year, he had wanted to introduce him to his friends at Camp Half-Blood since he thought that Gohan was a demigod like him. Well, he was on the right track, just a little bit off.

They had finals all day, starting with English. For some reason, the teachers thought it was a good idea to leave all of the students in the school yard for an hour after reading Lord of the Flies. The results were pretty ugly. By the end of the hour, there were massive wedgie contests, rock throwing, and really violent tackle sports, most of which were led by the school bully, Matt Sloan.

"Honestly!" Gohan sighed as he watched the activities while standing next to Percy and Tyson. Actually, he was hovering a few feet above the ground. "Can't these people ever learn?"

"I know!" Percy began. "Sloan is such a- can we please kill him?"

"Don't tempt me." Gohan began. "The temptation is there, I just don't feel like wasting any energy on him."

"This is coming from the guy who is floating a few inches off the ground?" Percy asked as the bully in question came flying in their direction. It seemed he tried picking on Tyson, who'd swatted him away.

"Well well." Gohan began. "What do we have, here?"

"You freak!" Sloan shouted at Tyson. "Crawl back in the box where you belong! And you!" he shouted as he looked at Gohan and Percy. "You might have a few friends besides each other if you weren't friends with that thing! I swear, Jackson! Son! I'll be sure to get you in P.E.!" with that, he ran off and class ended with everyone passing.

"People with money and power always seem to think they are the best." Gohan began. "Just like Freeza!"

"Who's Freeza?" Percy asked as he recalled hearing that name before.

"I'll tell you about him later." Gohan answered as they headed for science class. Their goal was to mix some chemicals together and cause an explosion. Everyone was split into pairs. As Gohan saw Tyson, who was working with Percy accidently knock some chemicals aside, causing an explosion within less than thirty seconds. He chuckled at it as he mixed random chemicals together causing a similar effect only a few seconds later. It was in social studies when Gohan noticed that Percy truly was not normal. He finished the final there very quickly and saw Percy looking at a picture in his notebook of Annabeth and her family. "Wait a second. Is that-"

"What is it, Gohan?" Percy asked.

"Who's the girl in the picture?" he asked.

"This is a friend of mine I met a summer camp last year." Percy explained.

"I see. What's her name?" Gohan asked.

"Annabeth Chase." Percy responded. "Why do you ask?"

"That's who I thought it was." Gohan said as he glanced at the photo again. "She's certainly grown since our adventure."

"Huh? Do you know her?" Percy asked.

"Yeah. I knew her a couple of years ago. Now that is quite a story." Gohan answered as they headed for P.E. and paused when he sensed a familiar voice and a voice saying

"Percy! Over here!"

"What was that?" the demisaiyan asked.

"I don't know. I didn't know any girl here would ever speak my name. Well, we should get going." Percy said as he walked off with Tyson.

"I know you're there, Annabeth." Gohan said as he looked around. "You might as well reveal yourself." With that, a blonde girl appeared in front of him holding a baseball cap.

"You must be skilled if you can sense me, kid." Annabeth began. "Hmm. You look a little familiar. Do I know you?"

"Yeah. It's me, Go-" he was interrupted when he heard the minute bell and ran off towards the gym.

"Are you ready, Gohan?" Percy asked as they got dressed for gym.

"Oh yes." Gohan grinned. "This dodgeball game will be the perfect way for me to hurt that guy, though I'll try to restrain myself from killing him. Gohan knew it would be a challenge to restrain his saiyan strength, but he never thought he would have to restrain himself from seriously harming a human.

"So are you ready to get pulverized?" Sloan shouted as a group of huge people appeared next to him. "Why do I bother asking? Of course you are!"

"Smells funny." Tyson said as he looked at Matt Sloan's new friends.

"What?" Percy asked. "Them?"

"No. I think he'd right, Percy. There's something strange about them." Gohan said.

"You should listen to your friend, Perseus Jackson!" one of Sloan's new friends shouted.

That's when Percy knew something was wrong since nobody except those who knew his true identity addressed him by that name.

"Uh oh!" Gohan shouted as he saw his opponents grow in size. "Giants!"

"Wait. You can actually see their true forms?" Percy shouted. "Just what are you, Gohan?"

"I might explain that later, but for now we should focus on them!" Gohan shouted as everyone tried escaping through the doors when one of the giants threw one of the dodgeballs at it and closed it shut. Only it wasn't a dodgeball anymore. It along with the others turned into what looked like bronze waffle balls with fire within them.

"Hey! Let them go!" Percy shouted.

"No chance, son of the sea god! We wouldn't want to lose all of the tasty morsels or the dragon ball Son has! We laistrygonians want wish for eternal food!"

Gohan paused as he stared at the four star dragon ball he had around his neck, one of the only keepsakes he had that belonged to Goku. "What a wasted wish, and with one more to spare." He paused for a moment as he looked at the door. "If you know who I am, you should know that a door like this is nothing. KAMEHAMEHA!" Gohan shouted as a bluish blast emerged from his hands and destroyed the door. "Everyone, get out of here!" Noone had to think twice. The moment they saw the open door, everyone rushed out except for himself, Percy, and Tyson. "Son of the sea god?"

"I guess we both have something to explain Gohan, but I have an idea to get us out of this!" Percy shouted.

"Great, but do you at least have a weapon to take them on?" the demisaiyan shouted.

"Yeah. Do you think you can hold them off?" Percy asked.

Gohan grinned as his saiyan bloodlust seemed to burn within him. "These giants won't stand a chance." As Percy ran into the locker room all of the giants surrounded him.

"You won't get away, half blood!" the giant known as Joe Bob said as his partners threw fireballs at Gohan who simply phased out for a second as they passed through him.

"Wow. Large and dumb." Gohan smiled as he fired ki blasts at some of the other laistrygonians, vaporizing them.

"No! My brothers!" Joe Bob shouted." You'll pay for that, boy!"

"Hey! I'm not the alien!" Gohan shouted as he jumped over the charging giant. He glanced over to see how Tyson was doing and saw he was holding his own against some of the giants. "Let's see. Giants, I guess a Cyclops, I've seen weirder."

"Indeed, Goku!" Another giant shouted.

"Boy are you dumb!" Gohan said as he vaporized another one. "Confusing me with my dad?"

Percy ran in with his sword, Riptide upon hearing that and saw that many of the giants were gone. "I see you managed without me, Gohan."

"Nice sword." Gohan said as he flew over and grabbed it. "Do you mind if I test it?" he asked as he sliced through another charging giant, turning him to smoke as well. "Not bad, but Trunks' sword is better." With that, Gohan gave Percy his sword back and took out a capsule revealing the sword that once belonged to Future Trunks, repairs courtesy of the Ox King's blacksmiths.

"He actually touched my sword and used it?" Percy asked. "Then he must be a demigod!" Within seconds, the only giants left standing was Joe Bob who had destroyed most of the gym with fireballs and two others who were quickly dispatched by Percy.

"Say, why did they explode just from a sword cutting through them?" Gohan asked.

"They do that. You can't kill them for good, Gohan." Percy said as they stood in the remains of the gym as they were chased to the edge of the room.

"Lunch time!" Joe Bob smirked as he had the trio pinned against the back wall and fired, but Tyson jumped in the way and was hit in the chest by the ball, sending him into the wall as part of it collapsed on top of him. Thankfully for Percy and Gohan, it also revealed the nearby street.

"Let's see. Who dies first?" Joe Bob asked as he approached the boys. As he prepared to throw the fireball at them, a sharp object jutted out of his gut as he burst into flames. Standing in the smoke was Annabeth with a bronze knife in one hand and her cap in her pocket.

"Annabeth!" Percy shouted. "When did you-"

"I've been following you all morning! I just didn't get a chance to talk to you since you were never alone, usually with this guy!" Annabeth shouted as she pointed at Gohan. "Hurry up and meet me outside, and bring these two with you!" she shouted as she pointed at Gohan and Tyson. When they heard voices in the hall, Annabeth put on her cap and disappeared just as the adults swarmed in from hearing the explosions.

"Uh oh! How are we going to get out of here?" Percy shouted as he saw Tyson get up.

"Head hurts." He complained.

"Grab on to my shoulder!" Gohan shouted. "Both of you!"

"But how is that-"

"Just trust me." Gohan said as they grabbed on. "Let's see." He began as he put two fingers to his forehead. "Annabeth…got her!"

"Wait. What are you-" Before Percy could finish, they appeared outside in front of Annabeth.

So how was this for an opening? Like I said, it probably isn't the greatest, especially for an opening. I'm open for any input on how to improve future chapters.
