Warnings: As this story has an original female character in it, it is obviously Alternate Universe. In effect, it is also Non-Canon, if such a thing applies to an animated series. Whether or not Chiara is a Mary-Sue is a matter of opinion, but if she is, then she is, and I will not change that. I've tried to make Chiara as realistic as possible. This means that you're not always going to like her, you'll probably want to strangle her sometimes, but I think on the whole she's an alright person.

Each chapter will have individual warnings, telling you what to expect of each chapter. The length of each chapter varies. Sometimes it'll be a very short chapter, other times it'll be longer.

Notes: Any and all explanations can be found at the end of each chapter. I have grown to abhor author's notes in my own stories, but I can't just leave everything unexplained, so I'm forced to use them as I refuse to put notes in my story.

In closing I want to say that I had intended to write this story while following the dialogue of the episodes, but have now decided against it. For one thing it would become too much of an insert, as if it isn't already, and for another, it is extremely tedious to have to write down the exact dialogue of the series since I have to get it from the episodes I've taped. So while this story will follow the actual storylines with few exceptions, I wont be using the original dialogue. Up until the point where Radditz shows up at the Kame House is almost all actual dialogue from the dubbed series.

Warnings for this chapter: Violence, kidnapping, and cruelty towards children near the end.

Radditz Saga:

Chapter I: Where It All Began.

It was the 15th of May in the year 757 A.D when on a sunny afternoon Son Goku and Son ChiChi became the proud parents of very healthy and very loud twins. They were unidentical twins, as they were a boy and a girl, but looked very much alike nonetheless. The boy was named after his paternal grandfather, and he was called Son Gohan. The girl was named after her maternal grandmother, and she was called Son Chiara.

761 A.D. October the 12th.

"Gohan, Chiara, it's time to come in," ChiChi called, standing just outside the Son house. "Gohan."

While ChiChi called for Gohan and Chiara, Goku was leaping around in the woods looking for a tree that would make for some good firewood.

"Ah," he said, smiling up at a huge tree. "This one oughta do."

He pulled back his fist and let it connect with the tree, which promptly came down. ChiChi, in the mean time, was still looking for her two children.

"Chiara," she called, before smiling as she saw her husband coming. "Oh. Hey, Goku, do you think you've got enough firewood there?"

Goku dropped the tree to the ground and said, "Yeah, I guess that oughta do, don't you think?"

ChiChi sighed and worriedly said, "You're gonna hurt yourself doing that one of these days."

"Ah, I'm fine. Where are Gohan and Chiara?" Goku asked.

"I don't know," ChiChi said, a little worried as she glanced around. "But you better go and find them, because you three are supposed to be at Master Roshi's pretty soon."

"Oh yeah," Goku said with a smile. "That's right."

"You better take the flying Nimbus," ChiChi said. "You don't wanna be late for your reunion."

"Okay, bye, ChiChi," Goku called, as he ran off.

"Goku, be careful," ChiChi called after him. "Uh, all this worrying is going to give me wrinkles."

Goku went to find Gohan and found him sitting on a branch, clutching it for dear life.

"Help me," he cried. "I'm stuck up here, help, please."

He stopped crying out when he saw his daddy in front of him, sitting on the flying Nimbus. The little boy was freed from his 'predicament', they went to find little Chiara.

Chiara, in the mean time, was sitting at the side of a pond. She knew better than to get so close really, but she had always been curious where water was concerned. She leaned forward and reached out to the water surface with her little hand, when suddenly she heard someone calling her name.

She giggled as she darted behind a boulder. Her daddy was looking for her, but she wouldn't let him find her. Goku and Gohan landed nearby. Gohan stayed on Nimbus, while Goku got off to look for his daughter. Chiara giggled again as she heard her father's heavy footsteps getting closer.

"Now," Goku said with a smile on his face as he looked at the two small feet sticking out from behind the boulder. "Where did Chiara go?"

Chiara giggled again as she continued to hide. Gohan, who was still sitting on the Nimbus, had a big smile on his face. He knew where Chiara was, but he wouldn't tell. Goku crossed his arms over his chest, his smile widening as he thought of just the thing to get her to come out of hiding.

"Well, I guess Gohan and I will have to go to Master Roshi's with just the two of us."

A small gasp came from behind the boulder, and a small black-haired girl jumped from behind it and into her father's waiting arms.

"No," Chiara cried, tears rising as she clutched her daddy, "I wanna go too."

Goku chuckled gently as he hugged his little girl to his chest. "It's okay, sweetheart, I wasn't really going to leave without you. Hey, no tears now, okay?"

Chiara sniffed as she looked at her daddy, and nodded. Goku gently ruffled her hair, before walking to the flying Nimbus cloud. He scooped Gohan up into his other arm and sat down on the cloud. Both the Son children laughed and whooped as Nimbus took off at full speed. It was a fun ride for all three of them and soon they arrived on the small island that held the Kame House.

Goku jumped off Nimbus, who didn't stick around, with both half Saiyans cradled in his arms.

There was a small helicopter standing in front of the house, and Chiara marvelled over it as Goku walked to the house. Chiara wriggled in Goku's arms, trying to get him to put her down. With a confused look on his face, Goku put her down and watched her hesitantly make her way to the small chopper. He smiled at the sight, thinking it could do no harm, before calling out to anyone who might be inside.

"Hey, is anyone home?" Goku called.

The door to the small house opened and revealed Master Roshi, Krillin and Bulma. They all greeted Goku warmly before noticing Gohan.

"Hey, who's the kid?" Bulma asked.

"Goku babysitting?" Krillin quipped. "Well, I'll be darned."

Goku threw Gohan a fond look and said, "He's my son."

Jaws dropped as they looked at Gohan in amazement.

"Pretty wild, huh?" Goku said as he put Gohan down.

"Wauw," Krillin said, agreeing with Goku.

"And that's not all, he's one of two," Goku said proudly.

"Two?" Krillin questioned.

"You have another child?" Bulma asked.

"Yeah, she's right over there," Goku said, pointing at Chiara, who was carefully touching the side of the chopper, a smile appearing on her face. "Chiara."

Chiara startled and stepped away from the chopper, only to trip and fall hard on her backside. Gohan cried out, and quickly ran to his twin's side. As he helped her up, the others looked on with smiles on their faces.

"Oh, Goku, they're adorable," Bulma said.

Goku nodded with a smile, "Hey, you two, come and say hi."

Gohan and Chiara walked over to their daddy, Chiara's cheeks wet with a few tears. She quickly dried them as they stood next to their father.

"Now, say hi." Goku said to his children.

"Hello, everybody," Gohan said, bowing to them all.

"Hello," Chiara said shyly, bowing as well.

Master Roshi, Krillin and Bulma bowed back.

"These are Gohan and Chiara," Goku said.

"Gohan?" Roshi repeated. "I see, you named him after your grandfather."

"You're right," Goku said.

"What about Chiara?" Krillin asked. "Where does her name come from?"

"ChiChi's mother," Goku said.

Krillin nodded in understanding as Bulma knelt in front of Gohan.

"Hey, Gohan," she cooed. "How old are you?"

"Eh... Four and a half," Gohan said, holding up five chubby digits.

"Then you must be four and a half as well, huh?" Bulma asked Chiara with a smile.

Chiara nodded from where she stood, half hidden by her father's leg. "Gohan's older."

"Ah, he was born first," Bulma said in understanding.

Chiara nodded before shyly hiding her face in the fabric of her father's pant leg. Bulma chuckled softly before turning to Gohan again, but addressing them both.

"And are you gonna be brave fighters just like your dad?" she cooed, gently ruffling Gohan's hair.

"ChiChi doesn't let them train." Goku said.

"Oh," Bulma said. "No Martial Arts, huh?. What do you wanna be when you grow up, Gohan?"

"A orthopedist," Gohan said.

"Wauw," Bulma said. "An orthopedist, hm."

Turtle, in the mean time, was coming closer to Gohan and Gohan shied away.

"He's just saying hi, Gohan," Goku said.

Gohan looked at Turtled curiously, and Bulma suddenly noticed his tail.

"A tail?" she said.

"Yeah, he was born with it, they both were. Just like me," Goku said. "I think he wants you to pet him, Gohan."

Gohan smiled and petted Turtle happily.

"Oh, man," Bulma said as she got up, still caught up by the tails. "Goku, has anything strange ever happened to Gohan or Chiara at night?"

"What do you mean?" Goku asked.

Roshi stood next to Goku, "She means have Gohan or Chiara ever looked at the moon at night when it's full?" he said.

"I don't think so," Goku said, thinking for a moment. "No, we all go to bed pretty early."

Gohan was happily riding Turtle while Chiara made her way to the waterside. Goku checked on Chiara to make sure she wasn't going to near to the water and when he saw she stayed at a distance, he was satisfied.

"Why?" he asked, returning to what they had been talking about.

"Why?. Why you say?" Roshi laughed nervously. "No reason, I was just kidding around."

"They're alot different than you were when you were a kid, Goku," Krillin commented as Gohan ran to where Chiara sat, playing in the sand.

"I know," Goku said, almost wistfully. "ChiChi's pretty protective of them. She makes them study all the time and she says that Martial Arts are a waste of energy."

Gohan played Rock, Paper, Scissors with a crab while Chiara sidled closer to the water.

"Oh yeah?. Well, what does that make us then?" Krillin asked.

"Huh?" Goku said, turning his attention to Krillin.

"Now, now, settle down, boys," Roshi soothed. "You can't expect everyone to agree with what you're doing. It would be all too easy then."

Gohan won the game with the crab and got sprayed, making Roshi laugh and Goku smile until Goku saw Chiara all but in the water from the corner of his eye.

"Watch out, he might pinch you, Gohan," Roshi said laughingly, as Goku made his way to Chiara. "That crab is a sore loser."

Gohan laughed as he ran back to them while Chiara reached her small hand into the water and towards the glittering object she saw in it. She almost caught hold of it when she felt the sand underneath the hand supporting her shift and fall away. She cried out as she fell forward and closed her eyes, waiting for the water to swallow her. She suddenly felt herself getting lifted up into the air and away from the water. When she turned her head she saw her daddy looking at her with a disapproving look on his face.

"Now, what did daddy tell you about going too close to the water?" Goku asked.

Chiara swallowed hard and whispered, "You said not to."

"That's right. And there's a reason for that, you can't swim yet, and if you fall in, you could... get hurt," Goku scolded, not wanting to say drown.

Krillin, Roshi and Bulma looked on as Goku scolded Chiara, Gohan playing at Bulma's feet.

"And he says ChiChi is protective," Krillin commented with a smile.

Goku made his way back to his friends, his daughter cradled in his arms. He put Chiara down next to Gohan, and smiled at them both.

"Oh, how neat," Bulma suddenly said. "That's a real dragonball on your hat," she said to Gohan, before she turned to Goku. "Isn't it?"

"Yep, it was my grandfather's, I've been collecting them for fun," Goku said.

"Isn't Chiara upset that Gohan has it?" Bulma asked.

"Oddly enough no. She doesn't like the dragonballs very much," Goku said with a small frown. "When she first saw a dragonball as a baby, it made her cry. Now she just turns away from it, she won't even hold it."

"That is odd," Bulma mused thoughtfully.

"Gohan loves the dragonball, he wants to see the dragon but he'll have to give his up," Goku said.

Gohan scowled at that as he clutched his little hat.

"Wauw," Bulma said with a smile. "It's wild to think of all the things that we went through together trying to find those dragonballs."

"Yeah, really," Krillin agreed, picking up a stone. "Hey, Goku, so what are you guys gonna wish for when you get 'm all?" He then threw the stone over the surface of the water.

"I don't know, Krillin. That's a good question," Goku said, also picking up a stone. "Come to think of it, I don't really want anything."

Goku threw his stone, much further than Krillin, and with much more power. "Wauw," Bulma breathed.

'Hm,' Roshi thought. 'I thought Goku had less power now that he's settled down.'

"Heh," Krillin said with a smirk. "You're still one bad dude, Goku."

Goku smiled before suddenly tensing.

"What is it?" Krillin asked.

"Huh?" Gohan said as both he and his sister looked up at their daddy.

"What, Goku?" Roshi asked apprehensively.

"Man, something is heading straight for us," Goku said, a scowl on his face.

"What?" Bulma gasped. "Are you sure, Goku?"

"I'm positive," Goku said. "I've never felt a power like this before."

"I feel it now too," Krillin said grimly.

"There's nothing there, you guys," Bulma said, crossing her arms.

The wind suddenly picked up and the air around them seemed to change.

"What is it?" Goku said anxiously. "I've never felt anything this powerful. It's a horrible power too. I'm trembling. Impossible."

"There, there," Roshi cried anxiously, pointing at the horizon. "Oh, I see it, Goku."

"It can't be Piccolo," Krillin said, shielding his eyes with his hand to try and see.

"This isn't good," Roshi muttered, as the new threat came closer and closer.

Suddenly a very large man with long spiky hair landed on the island. Gohan and Chiara quickly stepped behind their father as Bulma, Roshi and Krillin took a step back. The obviously powerful man laughed as he looked at Goku.

"So we meet again at last," The man said in a deep and sinister voice.

Goku growled as both he and Krillin crouched down into a fighting stance. Gohan and Chiara were standing behind Goku as Bulma and Roshi stayed at what they hoped would be a safe distance.

"Who are you?" Goku demanded.

"Who am I?" the man repeated, a frown now replacing his smirk. "What is the meaning of this, Kakkarot?. Why hasn't this planet been cleared?"

"My name is Son Goku, and I don't know anything about clearing any planet," Goku said firmly.

"Son Goku?" the man said in disbelief. "I don't believe this. Stop this at once, Kakkarot, and answer my question."

"I don't know anyone called Kakkarot, I'm not clearing anything, and I think you need to leave," Goku said, his voice still firm.

The man seemed to be carved in stone as Goku said this, before the scowl on his face returned.

"Kakkarot, listen to me. Were you ever knocked on the head when you were a child?" he asked.

"What if I was?" Goku demanded, not relaxing in the slightest.

"What if you were?" the man yelled in fury. "You fool, you went and forgot who you truly are." The man calmed down and crossed his massive arms over his broad chest. "Well, I'll remind you. Your true name, as you know by now, is Kakkarot, and you are my younger brother."

"What?" Krillin cried.

"Impossible," Goku exclaimed.

"I assure you it is quite possible. My name is Radditz and I was sent to this planet to see why it was taking you so long to clear it for use. Now I see what has happened," Radditz said. "You have lost your memory and lived here ever since."

"What do you want?" Goku asked, his voice harsh.

"I want you to join me, Kakkarot, join me so that we may clear this planet now," Radditz said.

Bulma, Roshi and Krillin gasped in shock, as Goku growled.

"I will have nothing to do with your schemes," Goku all but yelled.

Radditz growled and clenched his fists, when he suddenly turned his attention to the two children trying to hide behind Goku. He had seen something. He moved faster than any of them could see, and snatched the small tail, bringing a screaming four year old high into the air.

"Let her go," Goku yelled, before attacking Radditz.

Radditz dropped a still screaming Chiara onto the ground, where she landed harshly, and Gohan rushed to her side as Goku and Krillin fought Radditz with all they had. Even combined the two were no match for the hardened Saiyan warrior, and both were thrown aside. Radditz turned to where he had dropped the girl and noticed Gohan, who had curled himself around his sister, trying to shield her body with his own.

"Two of them," Radditz muttered as he snatched both toddlers up by their collars. "The fool has mated with a human. No matter, they will serve me well."

"Leave them alone, you monster," Bulma yelled, still at a distance. "They're only babies."

Radditz ignored Bulma and walked to where Goku was desperately trying to get up to save his children, harshly kicking Goku in the ribs, sending him sprawling again.

"Now listen carefully, brother, I don't know what's wrong with you but you better snap out of it quick. I will give you one whole day, from now until midday tomorrow, to kill 100 humans, or the next time you see your brats, you'll have to piece them together before you can bury them."

Goku continued to try and get up as Radditz sneered, "It's high time these two knew their uncle anyway."

Radditz laughed and took off, leaving a beaten and angry Goku and Krillin, and a shocked and scared Bulma and Master Roshi.

It wasn't long before Yajirobe showed up with senzu beans to heal Goku and Krillin. Goku was furious and he swore he would get his children back without ever harming any humans, but how?.

That was when the unexpected happened, Piccolo showed up. And for once he wasn't interested in fighting Goku...yet. He wanted to know who Radditz was and what he was doing on Earth. Knowing that they wouldn't be able to defeat Radditz separately, Goku and Piccolo grudgingly decided to work together.

In the mean time Radditz had taken Gohan and Chiara to where his pod had landed. He locked Gohan in the pod, but kept Chiara with him.

"Now, for a little entertainment." He grinned before slapping Chiara across the face.

She landed hard on her stomach and sobbed in pain as she tried to push herself up. She cried out when she was pulled up by her hair and whirled around.

"Who's gonna save you now, little girl?" Radditz mocked as he held her up by her hair.

Chiara cried and struggled as she tried to pry Radditz' hand from her hair. Gohan screamed and cried as he was forced to watch. He didn't quite manage to burst out of the pod he was locked in.

Radditz laughed, "Not your daddy, that's for sure."

He threw her down and thought for a while of how he might be able to torture her. It came to him and he grinned down at her maliciously. Chiara sobbed as Radditz grabbed hold of her tail and very slowly and very painfully turned it inside out. Chiara screamed and Gohan screamed right along with her.

When Radditz got tired of hearing Chiara scream, he picked her up and dumped her into the pod with her brother. Chiara was crying loudly and Gohan held her, crying himself. While Gohan fussed over a nearly unconscious Chiara, Radditz turned away in disgust.

"Pathetic humans," he growled.

Not long after Goku and Piccolo showed up, having followed the dragonball on Gohan's hat, and the battle began. Goku and Piccolo fought Radditz but they were no match for him and they got pounded mercilessly. In the pod, Chiara passed out because of the pain. Gohan got very angry at Radditz for hurting his sister and burst out of the pod to attack him. The attack was short-lived but it gave Goku enough time to grab Radditz from behind and hold him so Piccolo could kill him, sacrificing his own life in the process.

Bulma, Krillin and Master Roshi had turned up during the battle and when it was all over, they mourned the loss of Goku and fussed over the twins, who were now both unconscious.

"Her tail," Bulma cried as she saw the bloody and mangled appendage "Look at her tail."

Krillin growled as he saw what Bulma meant and went to say something when a shadow fell over them. It was Piccolo. Bulma gulped and Krillin growled once more, Piccolo had been the one who killed Goku after all, no matter what the circumstances.

"What do you want?" Krillin asked. "The battle is over."

"This battle is over," Piccolo growled. "But if you had been paying attention you'd know that another one is not far away."

"So we'll train, and we'll be prepared," Krillin said but Piccolo ignored him.

Bulma gasped and Krillin cried out indignantly as Piccolo snatched the two demi Saiyans off the ground.

"Hey, give them back," Bulma all but shrieked.

"Where are you taking them?" Krillin cried.

"These two are coming with me, when those two Saiyans arrive on Earth, I'm gonna need all the help I can get to defeat them," Piccolo said. "If there is any strength in these two babies..." He nearly spat the word. "...I'll find a way to make it come out. A year of training should be enough."

Piccolo powered up and took off, carrying Son Gohan and Son Chiara with him.

"But...but...but..." Bulma stammered as Krillin watched on helplessly.

A silence fell amongst Bulma, Krillin and Master Roshi, until Bulma exploded.

"How dare that monster just take them?" she yelled. "Now what are we going to tell ChiChi?"

"A better question would be, who's going to tell ChiChi?!" Master Roshi cut in.

Krillin was silent until he became aware that they were both looking at him.

"Me?" he cried incredulously.

"Yeah, you. Who else?" Bulma demanded, her arms crossed. "You are Goku's best friend after all."

Krillin backed up a few steps, putting his hands up, "But... I don't know how to tell her."

"Well, you had best figure it out," Bulma snapped as she stalked to her helicopter. "Because she needs to know."
