First Law of Motion

"Every object continues in its state of rest or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it" – Isaac Newton

The island was unnaturally quiet as everyone stood outside, unmoving. Raditz stood on his own, facing Goku, who was closest to him, and then Bulma, Roshi, Krillin, and Goku's son, Gohan.

"Leave this planet." Goku demanded suddenly, raising his fist and stepping forward. Raditz chuckled.

"Or what? You'll kill me? Don't bother, Kakarot. Your power level is nowhere near mine." He smirked and tapped the device on his left ear. The green screen beeped and numbers appeared on the screen. "All of the power levels on this island put together are still nowhere near my skill level!" He laughed and stepped towards Goku. "So what's it going to be, little brother? 100 dead humans this time tomorrow? Or am I going to have to harm my only nephew?" His eyes looked past Goku to Gohan, who squeaked and hid behind Bulma. Goku growled and took a defensive position.

"None of the above," he said, his eyes narrowing. "I'll just have to show you how we do things on Earth!" With incredible speed, Goku dashed forwards towards Raditz. Raditz grinned, and then disappeared. He reappeared in front of Goku and rammed his knee into Goku's stomach. Goku seemed to hover in the air for a mere second before Raditz spun around and kicked Goku into the rolling waves on the shore.

"No!" Bulma, Krillin, and Roshie yelled simultaneously.

"Daddy!" Gohan stammered out, struggling against Bulma's grip to get to his father.

"I guess it's the second choice, then." Raditz said, calmly walking towards Gohan. Bulma, in her terror, let go of Gohan, who immediately ran towards Goku. Goku was still clutching his stomach in pain, his face twisted into a painful grimace. A wordless howl was spilling out of his mouth. Raditz watched for a minute as Gohan cried while Goku screamed, then walked forward. In a silent and fluid motion, he picked Gohan up by the back of his shirt. The others watched in horror.

"I'm sorry it had to come to this, Kakarot. I hate knowing that I have to…dispose…of my nephew." He said, looking at Gohan and grunting. "But maybe I won't." He said, looking up at Goku now. "He has Saiyan in his blood. Maybe I'll keep him alive; he's got to have some kind of use." Goku groaned again in pain, spitting up a globule of blood and saliva. "But you'll probably never know," he added, shaking the young boy. "Now Kakarot, I must be off now. I expect to find 100 bodies here tomorrow, this time. If you fail, there will be only one dead body: your son's." With those words, Raditz pushed himself off of the island and became no more than a black dot in the sky before disappearing entirely.

"Gohan…" Goku sputtered, coughing up blood. Krillin, Bulma, and Roshi rushed to his side.

"Quit crying, brat." Raditz snarled, throwing Gohan onto the ground. He levitated a few feet above Gohan, watching him cry. His boots landed with a soft "tup" on the grass.

"Where's my daddy?" Gohan wailed, moving from a laying position to a sitting one.

"Don't worry about him," Raditz smirked. "You won't see him again anyway."

"You're not going to kill me, are you?"

"No, I think not." Raditz said, pausing to heave a great sigh. "You have Saiyan blood in you, you could very well prove to be a helpful asset." Raditz turned around and looked at his spacepod. There's enough room in there for me and the boy, he thought. He's not Kakarot, but he's half Saiyan, at least. Better than nothing. We'll train him well.

"C'mon, boy." Raditz said suddenly, grabbing Gohan and walking towards his spacepod.

"What're you doing?" Gohan whimpered loudly. He started thrashing in Raditz's grip.

"We're leaving," Raditz said simply; he jumped down into the crater that his ship created when it landed.

"Where?" Gohan asked in a quieter tone. He had stopped thrashing and now as unnaturally still.

He must be terrified, Raditz thought, grunting. The Saiyan blood running through him will come out when we show him what it's like. He threw Gohan into the pod and climbed in.

"Welcome back, Raditz!" His ship chimed happily. "Where are we off to today?" Raditz punched in a few coordinates and leaned back.

"To the planet Tarish." The ship beeped quickly before shooting into the air; it quickly cleared the stratosphere and within minutes, was outside the atmosphere.

"Better get comfortable, brat." Raditz grunted. Gohan sniffled.

"Why?" He asked, whipping his dripping nose. A fine mist began filling the spacepod and Gohan shifted uncomfortably next to the bigger Saiyan, who pointed to it.

"That's sleeping gas. We won't reach Tarish for about a year." Almost on cue, Gohan burst into tears again. However, to Raditz's surprise, the young boy merely cried instead of asking more questions. "See you in a year." He sneered, closing his eyes. Gohan gave a shuddering heave to regain a normal breathing rate before doing the same.
