Outer space. A silent and cold place, illuminated only by the stars. Life everywhere took millennia to devellop the technology to course through it, interplanetary travel was still in its infancy. Cruising through the western galaxy a spaceship of enormous size seemed to soundlessly drift past planets. The scanners on board were checking each and every one of them for the possibility of life. Inside a young Daxterian, one of the thousands of survivors, was vacantly staring out one of the windows. He sighed, silently wishing that none of past events had taken place. It all started with the arrival of the giant.
Six months ago, back on their home planet, a giant man crashlanded on their soil. He seemed to be starving and was suffering from dehydration, but was still very much alive. Compassionate as his kinsmen were, they quickly sent out a rescue team with food and water to retrieve him. It was the first time for their kind to encounter an alien life form and so the Daxterians had every intention of hailing him as a celebrated hero. Surely this was to be the start of a beautiful diplomatic friendship between them and the giant's kind.
Nobody knows for sure what happened, but it was rumored among the survivors that as soon as the giant had replenished his strength with the nourishment delivered by the Daxterian team he went berserk. One of the members of the team was able to broadcast a radio message to the home base but inbetween the cries of agony and sounds of static mixed with destruction and chaos only a fraction was intelligible.
Nobody knows what provoked the giant into attacking, but the radio message was all too clear:
(sounds of the radio message starting, in the background a Daxterian shrieks in agony)..."-ere is Vege- (an explosion could be heard, the person carrying the radio cursed loudly before suddenly going quiet) ...Guess he's not here..." The last few seconds of the recorded message are a devilish maniacal laugh, said to have been from the giant, before the connection was terminated.
Before too long the giant was sighted again. The Daxterians were unable to track his movement on their planet, but when simultaneous messages came in of entire countries being laid to waste by a giant with golden hair they wasted no time. Though they had only just develloped their largest craft, it would have to be their only hope at survival of their species. Worldwide dozens of craft were loaded up with as many people as possible. Each craft had the capacity to carry well over 3,000 Daxterians, a minute number when compared to the global population. Soon the craft were full and the doors had to be closed. Other Daxterians, unable to find a way to get off their home planet and avoid certain doom, decided to aid the Daxterian united military in trying to stall the giant should he come to their region.
Within the hour of the doors being closed, the craft started taking off. The craft were supposed to be the most powerful and fastest known to Daxterians, so nobody was prepared for the bloodbath that ensued.
One by one the giant seemed to be hunting down the craft. His thunderous laugh terrified the fragile Daxterians to their core and because radio contact was kept between craft, the cries of dying kinsmen echoed through the corridors of every other craft, reduced in numbers until only a handful remained. It was at this point that the military became desparate. If the others couldn't escape the entire race would be wiped out. Worldwide they decided to launch and detonate their most deadly weapons: a variation on the earthen nuclear bombs. As the last remaining people on the planet wiped themselves out with these dreadful weapons, some passengers noted the giant turning to face the explosions, hovering in midair. The crimson robe wrapped around his waist flowed in the wind as the giant seemed to simply be laughing at the foolishness of the suicide mission chosen by the Daxterians remaining on their planet. A green barrier appeared around the giant, who ascended into the sky, shooting past the craft. After breaking through the planet's atmosphere he turned around and pointed an open hand at the planet. After this nobody knows exactly what happened as the only craft in his vicinity was destroyed and the passengers of the last remaining spaceship were knocked out by a shockwave.
When they awoke they found their craft drifting through space, its engine disabled beyond repair. There was no trace left of their planet, or of the giant.
On a different planet, a supreme being was awoken quite abruptly as one of the planets in his domain seemed to have faded completely from existence. "Another one? Looks like he's in a hurry now..." The Kai scratched the back of his head, not entirely sure how he was going to handle this one. Silently he hoped the being would head to the Northern galaxy next. At least then it wouldn't be his problem anymore. Besides, the Northern galaxy had been swarming with other Super Saiyans lately...
