Part 1
"KAMEHAMEA!!!!!" The blue surge of energy left Gohan's hand headed straight towards Piccolo's head. But, with a swift motion of his hand, the Namek deflected the blast into a mountain blowing it to billions of pieces.
"Come on Gohan is that all you got?" Piccolo said. Gohan chuckled.
"Yeah right." The boy disappeared quickly, only to reappear quicker in back of Piccolo, and throw a punch towards his head. The punch was easily blocked by Piccolo, only to have a leg slammed into his gut. Just as the young Saiyan was about to plant his fist into the Namek's face, Piccolo disappeared just as his young sparring partner had done. Gohan was flung forward as Piccolo's leg struck his back. He teleported a ways to meet Gohan's flying body, with a punch, sending him soaring the other way. Gohan maintained his control and landed on his feet, rubbing his face.
"Not bad for an old man. But try this on for size." Gohan powered up, and surrounded himself with a golden aura, as he powered up to Super Saiyan. Piccolo tried to match the ability by powering up. As he was still flaring with green energy, the boy moved quicker than the eye to see, placing himself above Piccolo, landing a kick right in the face. Piccolo flew forward, landed, and threw both hands in front of him, releasing a thick line of ki. Gohan matched his blast, by firing a Masenkou, the two blasts exploding where they met. As the smoke cleared, Piccolo looked around for his young partner, and found him as a separate blast hit him in the back from above. Piccolo played possum, and lay lifeless on the ground. Gohan began to get worried. He hovered back down to the ground, and a worried look came over his face.
"Piccolo are you okay?" With a fast flick of his leg, Piccolo swiped Gohan off his feet and uppercut him in the head before he could even touch the ground. They both jumped to their feet, and got into battle-ready positions. They glared at each other for a while, before bursting into laughter.
"You're getting very strong Gohan. I trained you very well."
"Don't flatter yourself Piccolo. But you're not doing so bad yourself." The aura faded from Gohan, and his hair color returned to it's normal black. Just as the rest of the Z team gathered around their two partners, their attention was ripped from Gohan and Piccolo by a large object hitting the earth, sending flames all around, scorching the ground, and making a huge crater in the ground. They all started running towards the blast, but stopped as they saw another object coming towards them. It started small and formless, but as it got closer it's appearance changed from a small glob of black to a tall young boy running towards them. They all jumped back as he yelled to them.
"HELP MEEEEEEEEE PLEASE!!!!!!!!!!!!!!" Goku used his supreme sense of vision to zoom past the boy. And what he saw gave the boy reason to scream. A man with dark gray hair, in a long black flowing coat, who was shooting beams at him from behind, was chasing the boy. They all levitated into the air and flew at a fast pace past the boy, and landing to form a wall in front of him. As the man was about 10 feet away, he stopped, and put his arms to his waist.
"Step aside gentlemen, this is none of your business." He had somewhat of a deep voice, and he was about 6 foot tall, with gray hair parted down the middle, reaching down half way to his shoulders. He was built pretty well, and he looked to be in about his late 20's, early 30's. The Z warriors ignored his command and stood their ground.
"As I said gentlemen, step aside, this is none of your business. This is between the boy and me. If you don't move, I'll be forced to make you move." They did move, but not as he wanted. Instead of stepping aside, they formed a circle around him, and Trunks let out a laugh.
"Make us move? Ha, that's a laugh." The man looked around him at the circle of warriors surrounding him. He put his hand up to his fist, and cracked his knuckles.
"All right, now you've offended me. Apparently I'll have to make you move." A grin came to his face, as he faded away. The Z team said nothing and just stood there staring where their eyes were fixed. He reappeared behind Piccolo, and threw his fist towards the green man's head. The man grimaced in pain as Piccolo's arm shot up, to grab his wrist, as quickly as he had thrown the punch. Piccolo turned his head to look at the man, and smiled.
"Don't worry about this one guys, he's only got a power level of 14,000,000. He shouldn't be a problem." The man's eyes grew wide, and his jaw dropped.
"How, how can you tell that without some sort of device???" Piccolo didn't answer but turned his head to the young Saiyan he was scrimmaging with before.
"Here Gohan, this one's headed towards you." He grabbed the man's arm with his other free hand, spun him around and threw him, heading straight for Gohan. Gohan responded by bending his forearm, then flinging it out, into the man's back, as he came spinning at him. The punch hit straight in his back, and sent him flying towards Trunks. Trunks spun around fully, and connected his leg straight into the man's stomach . The winded man was then redirected towards Goku, who with a large wind up, sent the man flying out of the circle, hitting the ground face down, and skidding along for a minute or two. When he got up, his eyes were close, and blood was escaping from his nose and lip because of the punch, courtesy of Goku. He got up on his knee slowly, and eventually stood hunched over. When he did finally straighten out, his back gave a loud crack from Trunks' roundhouse kick. He was obviously very angry from being humiliated, but was soon calmed by the idea that crept in his head. He smiled, and crossed his arms, the way Vegeta was standing at that point. He looked toward the last person who hit him, which happened to be Goku.
"Think you're tough huh? Well, I'll see tough you are after THIIIISSSS!!!!!!!" his arms were thrown forward, and he released a large purple trailed fireball. It was soaring towards Goku at an incredible speed. The closer the blast got, the bigger the smile grew on the mysterious man's face. And little did he know, Goku's smile grew bigger as well. The blast connected with Goku, and created a large explosion, covering the Z warriors with smoke and debris from the explosion. And as the smoke cleared to the man's delight, Goku was gone! He let out a humongous laugh and crossed his arms again.
"Well it appears your friend with the bad haircut wasn't as tough as he thought he was. Let this be an example to the rest of you. This is what happens when you mess with Den." Piccolo smiled.
"So your name's Den huh?"
"At your service frog man." He said sarcastically with a bow.
"Well, I just have one thing to say about your little fireworks show."
"And what would that be green man?" he pointed past Den.
"Look behind you." Den looked confused, and turned his body. And what he saw, he did not like. The man he thought he had just destroyed, was standing in front of him, his arms crossed against his chest, just as he had last saw him. Goku brought his fist back, and planted it into Den's face, sending him soaring backwards. Like a shot, he zipped behind him, and planted his other fist into his back, sending him the way he had just come from. He once again landed face down in the ground, and it took him longer to get up than the last time.
"Try this on for size Den." Goku said as he placed his hands behind his back, and put them in the position to charge his Kamehamea. Den stepped back fearful, as he saw the blue waves flowing from the sphere forming in Goku's hands. He thrust his hands forward, and let the large burst of energy escape. Den just stood his eyes very large. He just stood as the beam got closer and closer. He kept standing and staring even as the beam pierced through his stomach taking his insides with him. He was still for a minute or two, until finally his legs gave away, and he collapsed onto the ground. The blood was gushing from the hole in Den's abdomen measuring almost 2 feet wide.
"I think that did it." Goku said to himself. He gave on last look at the lifeless blood soaked body, then turned around and walked back to his friends who had already sat the boy down on a rock, and gave him something to eat. Goku put his hand on the boy's shoulder, and the boy looked up at him.
"First of all kid, what's your name?" the kid stood up and the team finally got a close look at what he look like. He was about 6 feet tall, with dirty-blonde hair parted down the middle about the same distance down as Den. He was built pretty well for a boy his age(which turned out to be around 15) and by the looks of his scars and burns, he had just been in a battle. Goku also sensed something about the boy. Something familiar he thought.
"My name is Naspha. I'm 15 years old, and that guy Den that was chasing, has been after me for months. You see, he was my girlfriend's ex, and he just wouldn't let go of her. I thought I could take him on, but I was wrong. To make a long story short that's what happened. I could tell you more if you have the time."
"We have all day." Gohan said.
"Well, like I said, my name is Naspha. The last planet I lived on was Nemish but I am originally from….."
"Planet Vegeta." Goku interrupted. "I knew I felt something familiar about you. You're a Saiyan aren't you?"
"Yes I am. I didn't know until I was about 6."
"What Super Saiyan level have you reached?" Vegeta asked.
"Level 2." He replied. "Amazing. Level 2 at the age of 15. But how is it possible that you are a Saiyan?"
"Well, do any of you know of the Saiyan Nappa?"
"Yes I know of him." Vegeta answered. "As a matter of fact, I killed him."
"So you are the famous Vegeta? I was very pleased to hear of the death of my father."
"Well, you're welcome I guess." Vegeta replied confused.
"Well, about 13 years before the destruction of Vegeta, my father Nappa was out with a lowly slave Saiyan women. He was drunk and wanted some pleasure, so one thing led to another, and I was as he said 'accidentally' created. Since he wanted nothing to do, with me, my literally poor mother was left to raise me all by herself. I first discovered my powers when I was about 6. Some drunken robbers were trying to rape my mother. Enraged, I threw my fist towards the men, and out shot a large bolt of energy swiping the men away. My mother and I kept quiet about it. I learned more about my powers later."
"I'm still a little confused." Goten said scratching his head.
"I'll tell you the entire story. It'll make more sense."
