Well now: this is my first DBZ fanfic, and as the title suggests it's loosely based on the OVA "Super Android 13", except for the fact that this is set in-between "Dragon Ball" and "Dragon Ball Z". Major characters will be Goku (obviously), Piccolo (for he is orsum) and some new Androids. Enjoy.

DRAGON BALL Z:

ANDROID ASSAULT

Chapter 1:

One Year On

The flames towered up into the air, mixing with columns of thick, ashen smoke. Orange light danced over the cracked streets and the crumbling sides of decimated buildings. Somewhere along the highway an overturned fuel truck still burned.

The two creatures had appeared out of nowhere mere minutes before. In moments they'd turned the streets outside their target into a warzone. Even now, the last of the police cars that had arrived was sent hurling through the air. In the heart of the destruction, the two responsible stood in front of the museum that was their target.

The one that had thrown the car lowered his arm. Behind a pair of half-moon glasses a pair of cold, white eyes narrowed and turned around. His appearance was far from anything that could be considered young; his skin was wrinkled and thick, grey stubble accumulated around the bottom of his face. The top of his head was bald and covered in liver-spots and he was dressed in clothing that would have looked more at home in Victorian London. Picking his top-hat off of the ground, he dusted it off and placed it back on his head.

"10!" he barked towards the entrance to the museum, "What's taking you so long?"

As if on cue, the bodies of three security guards were hurled through the museum's battered front door, rolling across the ground as their assailant levitated gracefully out through the front door. She couldn't have looked more different from her accomplice; vivid red hair framed her young face and carried on down to the hips of her toned body, dressed in an elegant evening gown.

"Sorry, 11," she said softly, "most of the guards weren't feeling that cooperative."

"Did you get it, at least?" the old man asked. "You know how I detest these modern cities. Nobody seems to have any manners nowadays."

"Of course I did," the young woman said, producing the item she'd procured from inside the museum. The old man nodded, chuckling darkly to himself.

It was a smooth, perfect sphere of orange crystal, roughly the size of a baseball, glinting beautifully in the light, with six ruby stars suspending inside it.

"Ah," the one called 11 smiled as he took it, placing it inside a pocket of his dinner jacket, "the six-star dragon ball. Excellent."

"That makes three," '10' recited. "Four to go, and then that just leaves the other part of our mission."

"Indeed. Speaking of which, I think this has been enough of a warm-up," the old one said darkly, "the next one should be much more interesting."

"The four-star ball," 10 nodded. "We've known where that one is from the start."

"Right. Just remember not to get too carried away… the mission is to kill him later."

"Of course. Those were the doctor's orders."

It had been five years since the fight with Piccolo at the last tournament, and on the whole, life was good.

Goku hummed an idle tune to himself as, with a lightning-quick motion of his hand, he plucked another fish from the river. The one nagging thought in his mind was that there wasn't going to be another tournament… apparently the whole thing had been permanently cancelled. Then again, there hadn't been an arena since Goku and Piccolo had fought.

"Aw, man," he said disappointedly as he studied the size of his catch, which was roughly the size of a small car. "I thought it was bigger than that. Oh, well, there doesn't seem to be much around, so this'll have to do."

Carrying the fish over one shoulder, he strolled back towards the house that now stood next to his old home. The new place was a lot bigger and more modern than Goku's grandfather's old shrine, but then again, there were two of them in this new one… and, he recalled brightly, three soon enough.

Chi-Chi, his wife for nearly a year now, was in the kitchen smiling down at a package. "Goku, there you are," she smiled, then her expression turned to a shocked stare when she saw the fish he was carrying. "W… what on Earth is that?"

"Lunch?" Goku shrugged, smiling, as he struggled to try and fit the creature through the door.

"Leave that for a minute and take a look at this," Chi-Chi said. "Look what we got in the mail from Bulma."

"Hmm?" Goku inspected the object, which was a tiny blue set of coveralls. "They look kinda small," he said sheepishly.

"It's for the baby," Chi-Chi said flatly, gently placing a hand on her swollen midsection. "The doctor says it'll be any day now. Here, it's kicking…" she guided Goku's hand.

"Wow," Goku smiled, feeling the tiny impact. "You think he'll have his old man's strength?"

"Well, even if the baby does, I don't want you dragging our child out fighting all the time, understand?" Chi-Chi scolded. "Although sometimes I can't help wondering- what do you think will happen to our baby?"

Goku smiled and glanced over at the object that sat on the middle of the table: the four-star dragonball given to him by his grandfather all those years ago. He was still sure that there was nothing he was more eager to pass onto his child.

The mountainside gave way, crumbling into a wave of tumbling rocks and billowing dust, as Piccolo relaxed the muscles in his outstretched arm. The force of the blast had crumbled the solid surface of the rock in a split second.

He returned the green arm, adorned with masses of off-pink muscle, to his side and looked at his handiwork, his twin antennae still buzzing with energy as his cape settled from the aftershock.

"Goku… I promise you; next time we meet I'll finish you for good."

Ok, that's the start of it. Since this is my first DBZ story, so I'm open to constructive criticism about how I used the characters and universe of the manga/anime. Androids 10 and 11 are, obviously, my own creations, and since they're obviously not as powerful as 16/17/18, keep in mind that this is long before Goku managed to become a Super Saiyan. Also, this won't be a straightforward Goku-and-Piccolo-team-up thing, but hopefully it'll be enjoyable. Oh, and I'm sure someone will be able to guess who that "doctor" is…

Next Time: Androids 10 & 11 attack!
