Sorry for not updating sooner! I have several courses to take, and computer programming is not easy.
"If you love someone you let them go-if they come back their yours, if they don't they never were."
Bulma jumped off the hover jet onto the sandy beach of Kame house. Pu'ar and followed by Yamcha hopped out onto the ground beside her, and he flashed her a dazzling smile-to his dismay, was ignored. The scientist capsulized her invention and nodded towards her friend, who knocked onto the door of the little house.
"Hey guys!" The ex-bandit waved at his long-time friends, namely a bald monk Krillin, a lecherous old man Roshi, the equally perverted pig Oolong, and Turtle.
"Yamcha! Haven't seen you in a while!" Krillin waved back, then leaned in towards his friend, "hows it going with the lady?" Yamcha shook his head, disappointed. "Man, Bulma's a hard one to get, eh?" Krillin nudged his friend, who just sighed. Behind him Bulma appeared. "Krillin! Roshi! Turtle and Oolong! Long time no see everybody!"
"Hey Bulma! You got a boyfriend?" Krillin asked. Bulma quirked an eyebrow. "No. Why?"
He shrugged.
YYYYYYYYYY
Goku landed on the shore of the tiny island. He hopped off nimbus, keeping his hand on a child. "Oof! Here we are!"
At that instant, on hearing his voice, the residents and/or visitors of Kame house came rushing out. "Goku!" Krillin yelled. "Nice to see you again!" Yamcha waved. "Hi Goku!" Bulma greeted. Then she noticed the little boy clung on to the man's shoulder.
"Goku, who's that? Are you babysitting or something?"
"What? Oh, right! Guys, this is Gohan. He's my son!" Goku proudly set the child down.
"What?!" Bulma rushed over. "Oh. My. Gosh! He is so cute!" Gohan blushed and shuffled nervously. "Hey kid, how old are you?" Gohan raises his fingers and begins counting. "I'm this many years old!" The child announced, holding out four fingers. "Aw! You're smart!"
"Yea... Chi Chi is kinda pushing him in his studies. Says she wants him to get an education." Goku scratched the back of his head in the usual Goku way. "Wow. I never thought that that tomboy Chi Chi would turn out to be a study-obsessed mum!" Roshi chuckled. He watched as his grand-mentee played scissors-paper-stone with a visiting crab.
Suddenly, Goku stiffened. He whirled around stared up at the sky, frowning. Bulma looked up, startled. Krillin narrowed his eyes and Yamcha scowled. "What's wrong?" Bulma demanded. "Someone's coming. Someone bad." Bulma paled. "Is it… -gulp- is it Piccolo?"
"No." Goku growled. "This guy beats Piccolo by a long shot."
YYYYYYYYYY
Radditz flew towards the strongest ki. Or, more specifically, the group of the strongest kis-not counting the namek, of course. He had just left behind a very stunned Piccolo and was now searching for his long-lost brother.
The long-haired saiyan landed on Kame island. He raised an eyebrow at the odd display of characters. "Kakarot." he addressed the man poised in a fighting stance, who looked identical to his late father. A wave of confusion spread across his face, "Are you talking to me?" Radditz slapped his forehead. "Yes, you! Kakarot! The earthlings are still alive, running around like the vermin! What happened to your mission!?" The Bardock lookalike scratched the back of his neck in a peculiar fashion. "What mission? Look, I dunno what you are talking about, or who Kakarot is. My name's Goku!"
Radditz opened his mouth to retort, but then clamped it shut realising he would get nowhere. He forgot! I can't believe that he lost his memory! Wait… lost his memory…? "Tell me, have you hit your head when you were a baby?" Goku thought for a moment. "Yea… I think…. I forgot, hehe." Just then, an old geezer spoke up. "There was a man named Son Gohan. One day…"
"...he found a baby in the woods. He was crying, so Gohan took the child home to raise him. He was old enough to be the boy's grandfather so that's what he became overnight-a grandfather. He named the boy Goku. However, Goku had a destructive streak and loved to break things, and was very rebellious. One day, while on a walk, Goku fell off a cliff and hit his head on a hard rock. Miraculously, the boy survived...
"...and he became a happy, loving child." Roshi finished his story. Radditz shook his head disapprovingly. "So that explains it."
"Explains what?" Goku demanded. "You are not from Earth. You were sent here as a baby, to eliminate this planet's life forms. Because of that, you escaped our planet's destruction. Your name is Kakarot, and I am your brother, Radditz."
"Brother!?" Goku yelped in surprise.
Radditz ignored him and continued, "The full moon releases our true power-" the z-fighters glance at each other worriedly "-and our most powerful form. I see you don't have a tail, but that explains why you were able to blend in with the humans. And-"
Bulma lost him at "tail". It stirred some memory deep inside her, something she had long before buried deep but now had awakened. Something about a tail…
"-our planet, Vegetasei, was destroyed when a meteorite-"
Vegetasei…Bulma frowned, deep in thought. Vegetasei… Vegetasei… Vegeta sei… Vegeta… Vegeta…
"Vegeta!" She squealed. "I remember! Vegeta!" Bulma jumped in celebration. Radditz growled, hearing his prince's name spoken with such disrespect. That idiot girl, how dare she! I should kill her for her insolence! And good it would do, what a strange species this is, even with such a ridiculous combination of blue hair and... blue eyes…?
A dawn of realisation settled over him.
"You have… Blue hair and blue eyes…" Bulma raised an eyebrow. "Yes…?"
Radditz narrowed his eyes. "You… know Vegeta." It was a statement more than a question. Bulma looked at the saiyan in the eye. "Vegeta, prince of all saiyans?" She confirmed.
"But… how? When..?" Radditz asked. He had a good guess… a very good guess. Bulma smiled sadly. "Ten years ago."
That was it. "You met him ten years ago on some odd planet with a red sky and blue sand. He gave you a ship." Radditz said. Bulma nodded. Radditz pursed his lips. Ten years ago… that's when everything changed. That's when HE changed.
The saiyan sighed. "I have to call someone." Radditz blasted off into the horizon, leaving a very confused group of fighters staring at his disappearing figure.
