Author's Note: I have wondered what things would be like if Yugi Moto was actually a Saiyan or had some Saiyan genes in him.

Prologue: Escape from Frieza
Deep in a distant part of space a long time ago, there was a huge explosion. One strange ball-shaped spaceship was flying away from that explosion containing a severely injured woman, probably very close to knocking on death's door. Soon, two other ships were seen following the first and the woman inside heard a voice, an all too familiar voice, coming from the device she wore on her left ear. "Get back here!" it shouted. "I admit you at least have a few brains trying to run, but this is pointless! We'll catch up to you sooner or later, and then you're dead just like the rest of them Saiyans!"
The woman just responded with "Shut up, Dodoria!" and increased the speed of her ship. Doing so was quite risky, but she was willing to take the risk. Anything to get away from this Dodoria and the certainty of death, but her actions were beginning to take their toll on her ship, as electronic systems were overloading, and there were small explosions inside, but at least she was escaping.
A second voice then spoke. "Dodoria, Zarbon, why are you letting the Saiyan get away?" it shouted, whereupon a third voice, probably Zarbon, told it "Lord Frieza, she is placing enormous strain on her pod's systems, so at this rate, she'll do the job without us needing to lift a finger." For a while, there was no response, but then: "Alright then, come to think of it, one beaten Saiyan female is hardly a threat to us so we shouldn't really even bother. Dodoria, Zarbon, return to the ship," Frieza instructed, "…and sever the connection with her Scouter already for god's sake you idiots!"
After that, all three of the voices stopped talking. At least the woman's gamble was paying off. She still kept her spaceship's speed high in case they were actually pursuing her, and she set it to go to somewhere out of the way, where Frieza's men wouldn't come looking. The planet Earth came into view, and soon, she entered its upper atmosphere. However, the strain on her ship while increasing her speed to escape had destroyed its shields and it started burning up in the atmosphere as a result. Soon, it collided with the ground, disintegrating upon impact, the woman barely surviving as she crawled out from the wreckage. The last thing she remembered was a few people coming towards her, after which she saw no more… for the time being.
