A/N: This is just an idea that popped into my mind and I had to write it, Bulma and Gohan are twin demi-saiyans whose father is Goku. I am going to somewhat follow the story line of dragonball z but the slight change is obviously that Bulma is Gohan's twin sister and they both are going to be 8 years old. Anyways I hope you enjoy the story!

I DO NOT OWN DBZ OR ITS CHARACTERS

Chapter one

Little Gohan and Bulma were sparring outside their home in the woods with their father spectating and correcting their moves as they went. "You guys are looking really good, and I can't believe your power levels are already so high" Goku said with a bright and cheery smile on his face. "Thanks!" both Bulma and Gohan said at the same time with a bright smile as well. "But you guys know that if I don't get you home soon to study your mother is going to kill me, and by all the dirt and cuts on you face she is definitely going to know that you were fighting." Goku said with a slightly scared face, for he already knew the trouble he was going to be in when he got back home. Both kids sighed in defeat before agreeing with their father and jumping on flying nimbus to head back home.

"You know Gohan I don't know why mom still has me study I'm practically a genius, just the other day I repaired the dishwasher for her" Bulma said tiredly. "I know what you mean Bulma we are practically at a high school level in our education" Gohan replied just as tiredly. "You two better not let her hear you complaining she will only make you study more" Goku said matter-of-factly. "He is right" Bulma sighed out while jumping off flying nimbus so she could walk the rest of the way home with her father and brother.

Just as they were walking in the house they could all hear Chi-Chi's voice from inside the kitchen "I hope all three of you are back from fishing I have dinner waiting here for you on the table." Gohan and Bulma both looked at each other with a face of pure happiness as they ran into the kitchen to eat the amazing food that they knew their mother cooked. "Oh my gosh look at you two" Chi-Chi yelled while glaring accusingly at Goku as he walked into the kitchen. "Goku-Son, you let them fight didn't you!" Chi-Chi all but yelled in his face in nothing but pure rage. "It wasn't his fault momma" Gohan piped up in the most innocent voice he could conjure up, "Gohan is telling the truth mother, we had to beg dad to let us" Bulma said agreeing with her brother. Chi-Chi's glare just hardened as she looked at Goku "now you have them lying for you to cover up your tracks." "No Chi-Chi I swear I was all against them fighting, I told them that they needed to either fish like we said we were or go home and study. But they gave me the puppy eyes and you know I can't say no to the puppy eyes" Goku all but whined out. Chi-Chi just sighed in defeat "Whatever its already over with there is no use in arguing over it now, we should just sit down and eat and forget that any of this happened."

"Hey Gohan do you want to sneak out tonight and spar some more" Bulma asked excitedly. "I don't know Bulma mom seemed pretty mad a minute ago and we should push her buttons anymore tonight" Gohan replied in a shaky voice as if his mother already knew what they were talking about. "Don't be such a baby Gohan, how are we ever going to be as good of a fighter as dad if we don't practice as much as him?" Bulma asked incredulously. "I don't know Bulma but I was thinking that maybe studying and going to school to make something of our lives isn't such a bad idea" Gohan said with a smile on his face. Bulma just stared at him as if he was stupid *what the heck is Gohan thinking, I could never just sit here all day and study. I want adventure I want fun, I just want something exciting to happen to us* Bulma thought to herself "If you say so Gohan but I'm still going to go practice a little tonight so if you change your mind, you know where to find me" Bulma said.

The next day Goku walked into Bulma's room to wake her up for breakfast but when he entered her room he noticed she was not on her bed. Staring on in confusion he started to search for her Ki only to find that it said she was indeed in her room. Even more confused he decided to walk around and see where she was, well he didn't have to walk far because as walked over to the other side of her bed he noticed her lying on the floor sleeping soundlessly with dirt, scrapes, and cuts all over her. *She has been training in secrecy again, man what am I going to do about her* Goku thought with a smile on his face and look of adoration. "Bulma, wake up" he said to her prone form on the ground while shaking her non to gently. "Ugh, go away" she mumbled back only causing Goku to laugh "maybe you wouldn't be so tired if you weren't up all night training" Goku said accusingly. Bulma's eyes quickly shot open at hearing what her father said "I wasn't up training all night" Bulma said with a nervous laugh "mmhmm sure you weren't, you know you can't trick me Bulma I'm your father and that means I can tell when you're lying" he said with a chuckle in his voice.

At hearing the chuckle Bulma instantly knew that she wasn't in trouble, she had only amused her father so she smiled sweetly and put on an innocent face "I'm sorry daddy I should have never went training in secrecy, or lied to you. Please forgive me" she asked in a sweet and innocent voice while giving her father the puppy eyes. *That's right dad just look at my face, you can never say no to the puppy eyes* Bulma thought smugly. "Oh okay, you know I can't stay mad at you" Goku replied "Now go take a shower before breakfast because if your mother catches you she won't be so nice." Bulma just nodded her head in agreement before stalking off towards the bathroom. "Now to go wake Gohan" Goku thought aloud.

Bulma walked into the kitchen after getting showered and dressed and looked at her family sitting around the table eating, with a small smile she walked up to the table and said good morning while grabbing a plate and shoveling ceiling high full of food. "Good morning sweetie" Chi-Chi replied sweetly while looking down at her daughter lovingly. "Did you have a good night's sleep?" she asked. Bulma face instantly shot to her father's her gave a sly smile before going back to shoving his face full of food again "uhhh, ummm yeah great night's sleep actually" Bulma replied smoothly. "That's good dear, after breakfast though I want you to make sure you get yourself ready to look nice, your father has decided to go visit some of his childhood friends and he wants to bring you and Gohan along for the ride" Chi-Chi said. Bulma looked at her brother as if asking what friends and at seeing her face Gohan just shrugged his shoulders and went back to eating.

After they were all done eating Bulma and Gohan headed outside to meet their dad on flying nimbus. "Father who are you taking us to see" Gohan asked shyly, "Yeah dad, you never mentioned this to me earlier this morning" Bulma said accusingly. "Well I wanted this to be a surprise, and you will meet them when we get there" Goku replied in a voice that meant the subject was now dropped. Gohan and Bulma just grunted in disapproval at not being told what was going on, but didn't further push the issue. As flying nimbus started to move Gohan and Bulma grabbed ahold of each other and held on for dear life to where ever it was they were going. They were so far away from home that they couldn't even see the forest anymore and not to long after they were gliding over nothing but crystal Blue Ocean. *Where the heck is he taking us* Bulma and Gohan both thought at the same time. But they didn't have to think any longer because they started to see a small island in the middle of the ocean appear, and as the island got closer both Bulma and Gohan noticed that flying nimbus' speed started to decrease until they were finally descending nimbus onto to the plush sand of the island. Gohan and Bulma looked on with curiosity at the small pink house that said 'Kame House' Bulma looked over at Gohan "Hey do you think this is the guy that dad told us taught him the Kamehameha wave" Bulma asked excitedly "I think so, it would only make sense considering the name of the house" Gohan responded just as excited. "Wow I hope so, I can't wait to meet the great master that taught our father" Bulma all but squealed in her excitement. "I know" Gohan said with a huge smile on his face.

Just as they were talking in hushed excitement a small all old man with sun glasses, a short white beard, and a turtle shell on his back came walking out of the house with a bald man that had dots on his forehead, and a pig in overalls on trailing behind him. Bulma took in the outfit of the bald monk and noticed he had on the same training gi as her father "psst, hey Gohan look at that bald guy over there he is wearing the same clothes as dad. Do you think this master taught him as well" Bulma asked not even looking at him "I think so, let's go see though" Gohan replied. But before the two of them could run back over to their father they watched as the bald one they were just talking to beat them to the punch, they watched as he embraced Goku in a quick hug before talking excitedly to him.

"Wow Goku it's been so long since I have seen you" Krillen said with a bright smile on his face "yeah I know Krillen, I have really missed all you guys" Goku said as the rest of the group walked over to him in greeting. "Well well well if it isn't Goku what are you doing here if you don't mind me asking" Master Roshi said with a goofy grin on his face, "actually I came here to introduce you guys to my kids, and to say hi I haven't seen you guys in a while" Goku said awkwardly while rubbing the back of his head nervously. "I was wondering who those two squirts over there were that were looking at us funny" Oolong said. "Kids woah Goku you certainly have been busy huh?" Krillen asked Goku just chuckled "well I guess you could say that Bulma, Gohan come here there are some people I want you to meet" Goku said while smiling brightly at them.

Gohan hesitated at first but as he saw Bulma start walking towards their dad he grew more confident at knowing he would have her by his side and started to follow after her. Bulma made it to her dad's side and watched as Gohan walked over to his other side and hid behind his leg. *I see Gohan is as shy as ever* Bulma thought with a slight chuckle. "Gohan, Bulma I want you to meet Master Roshi, Krillen, and Oolong and guys this is Bulma and Gohan" Goku said happily. Bulma smiled sweetly at everyone while Gohan shied away behind his father's leg. "Well aren't you a cutie" Krillen said smiley sweetly to Bulma, "Thanks but I already know that" Bulma shot back with a wicked grin on her face that made everyone start laughing. "Well Goku I'd say you have a feisty one on ya" Krillen with a laugh "don't I know it" Goku said laughing as well. "And what about this one" Roshi and Oolong both asked about Gohan "Gohan is a little shy" Goku replied while nudging Gohan out of his hiding his place, everyone chuckled at the expression on his face and started to talk and get to know Gohan and Bulma better; and just as things were starting to get good Goku's head shot up towards the sky where he looked on with slight fear and confusion. "What's the matter daddy" Bulma asked with a slightly nervous hitch to her voice "I feel a strong power level heading this" Goku said nervously "why don't you and Gohan head inside with Roshi and Oolong while me and Krillen figure out what is going on." "No way I'm staying out here with you if this thing is dangerous I want to fight too" Bulma said desperately "yeah me too" Gohan shouted.

Before Goku could even begin to argue back a large man about the height of Goku with long brown spikey hair that ended at mid-calf landed right in front of them with a sinister look on his face that promised hurt. "Are you Kakarot?" the man asked looking at Goku, "Kakarot? Who is Kakarot" Bulma bravely asked. The man looked at Bulma and sneered just as he was about to say something snide back he noticed she had a tail as well as the boy standing behind her, totally ignoring Bulma he looked back to Goku "You are Kakarot I know it, if you weren't your two brats wouldn't have tails" he said while laughing merrily as if he had just told a good joke. "He has a tail too!" Gohan shouted, at hearing this Goku quickly stepped in front of his children taking on a defensive stance "who are you and what do you want, I don't know who this Kakarot is that you are looking for but you need to leave" Goku said threateningly. The man just chuckled "I am Raditz a saiyan from planet Vegeta-si and I have come her in search of my brother named Kakarot, who is for you information you" he said while still staring at Goku. "Goku is an alien?" Krillen all but gasped "I guess it makes sense he has always been inhumanely strong, and that tail just wasn't normal" Roshi said. Bulma side stepped out from behind her father "are you trying to tell me that my dad's an alien which would mean in a way that I'm an alien, and also that you are my uncle?" Bulma asked in disbelief while looking skeptically at the man named Raditz. Raditz smirked evilly at Bulma "yes little girl that is right, and I have come to ask my brother why he hasn't purged this planet y" But before Raditz could continue a startled gasp came out of his mouth "Oh my God Kakarot what the hell happened to your tail" Raditz asked incredulously while staring wide eyed at the spot that should have been Goku's tail. "It got cut off, why?" Goku asked suspiciously, "Kakarot our tails are our main source of power it's what defines us as a saiyans" Raditz practically screamed in his face.

"Listen hear buddy none of us know what a saiyan is and why the heck do you keep calling Goku, Kakarot?" Krillen said, but before he even saw it coming Raditz smacked him into the side of the Kame House. "Hey what the hell did you do that for" Bulma screamed at him. Raditz just laughed "that little girl was to teach him his place and I'll gladly show you your place as well." Bulma's face turned beat red in anger and just as she was about to launch herself at Raditz Gohan pulled her back "stop Bulma he is extremely strong are you trying to get killed" Gohan hissed nervously in her ear.

"Well Kakarot I'm glad to see one of your children has a saiyan fighting spirit" Raditz said while taunting Bulma. "Listen I don't know what you're talking about when you call me a saiyan or say that my name is Kakarot but I can assure you that you are not my brother and even if you were I would never consider you my brother especially after asking me why I hadn't purged earth. Earth is my home I would never destroy it" Goku yelled to Raditz. "Well I'm telling you that you're a saiyan as well that was sent her via pod on a mission as a baby to destroy this planet and that your saiyan name is Kakarot. You must have hit your head as a baby or something for you to have memory loss" Raditz said agitated. "Goku I do remember your grandfather telling me a story about how you were once a very cruel and evil child but after you hit your head you were the sweetest kid he had ever met" Roshi said matter-of-factly. "Ha you see that's it Kakarot you just lost your memories but you can still redeem yourself and purge this planet now" Raditz said. "I would never purge this planet, I don't care if I did lose my memories this is my home and I intend to protect it even if that means from you" Goku growled out "YA!" yelled Bulma and Gohan.

But before anyone could even realize what was going on Raditz punched Goku hard in the stomach making him double over pain, he then quickly snatched Bulma and Gohan up and floated into the air "I'll give you a second chance since you're my brother, I want you to kill 100 people by tomorrow. If you do this then I will give you your kids back" Raditz said while laughing evilly and flying away.
