CHAPTER TWO - Super Android Eighteen Vs. Kid Buu

"So," said this new stranger. "You think you have the advantage. I beg to differ."
Goku didn't know who this stranger was, but he felt no ki from her. This meant that more than likely she was an android. She looked like android eighteen, except for the fact that her hair was long and white, and she was about six feet; a few inches taller than android eighteen. Could she be related to android eighteen?
"Who you?!" Buu demanded, looking up at his latest aggressor.
With a quick movement, she put a section of her hair behind her ear, and smiled; she was very confident with her posture.
"Me?" She said, her voice with a questioning tone. "I'm super android eighteen!"
Goku gasped at this claim; she certainly looked super, but how did she go from her normal self to this much, much more powerful form? Well, he'd ask questions later; right now, if she could take on Buu, she was definitely worth it. She didn't even need words; she proved that she was worth it. As Buu threw hits at her, she dodged his strikes. That is, until she just seemed to stop, letting him hit her quite hard.
KAWHOOM! Kid Buu unleashed a series of strikes. He kneed her in the gut, kicked her upwards, then teleported up and sent her into the ground with an axe-handle smash. He then flew down to the ground, uppercut her, sending her up, then sending her through a mountain with a powerful kick. Goku and Vegeta were confused as to why he was beating the crap out of her, and she wasn't fighting back. Buu's onslaught continued.
Everyone was confused, but Piccolo seemed to understand the whole thing perfectly. Goku and Vegeta turned to him, wondering why he was smiling widely.
"What's up with you, Piccolo?" Goku said. "She's getting kicked around easily!"
He turned to Goku, his confident smile wide. "Goku, she's taking hits, but no damage. Remember that androids have infinite stamina? She has an endless supply of reserve energy to draw from, so this is a cakewalk."
Goku suddenly realized that he was right; it was true, she wasn't weakening. Buu didn't realize that his attacks were doing little to damage her. Right now, he was lavishing in himself as he repeatedly knocked around the female android. His attack on her was taking much of his reserve energy, and that is what she was hoping for. Goku and the other z-fighters in the area were all cheering her on, Vegeta being the greatest cheerer. Buu grabbed super android eighteen by her head, and began to spin her around in a circle very fast, and released her, causing her to hit the ground very rapidly. Buu descended to the ground, and struggled for breath as he laughed over what he thought was his easy victory.
So you can understand his horror when she stood up, dusted herself off, and began to walk toward him.
"You're quite good," she said, "that hurt. But, I've now seen all your moves and have calculated your fighting style. I've already won."
As soon as she finished saying that, she flew forward and kicked him so fast and so hard that no one saw her move. As Kid Buu struggled with much difficulty to stand up, he realized that he was not in for a good time. The good guys realized that their prayers had been answered. And Krillin was quite glad he was married to this woman.
