Examining the pod, Raditz was unsurprised but still disappointed at how bad of shape it was in. The outer shell had been beat to hell upon landing and, in the following twenty years of neglect, had been further damaged by the elements to the point that he wouldn't trust in the atmosphere of this weak planet much less deep space. Inside wasn't as bad as it had thankfully re-closed after ejecting his brother but even at a glance, Raditz could tell the majority of the life support systems had deteriorated.
Plugging in the spare battery from his pod, a couple of the secondary systems flickered to life. Booting up the system, Raditz ran a complete diagnostic on the ship. He was unsurprised to see that both the navigation and propulsion systems were both completely offline and the power converter was barely hanging on. However, the communications and data handling systems were both fully operation to his surprise. Raditz attached his scouter to the computer in the pod and began examining the data and, to his eternal relief, he found a copy of the fledgling Saiyan training program.
While Saiyan babies were naturally rowdy and loved to fight as soon as they were taken out of the infant gestation pods, they were still that: babies. Saiyan newborns were the human equivalency of 8-month-old developmentally; within a month of being born they started growing teeth and would want to eat solid foods, developed the ability to move around on their own, learned some basic communication, and had a decent but not great amount of hand-eye coordination. Still, that in no way meant that they would survive being dropped on an alien planet. True that it was somewhat of a natural selection for the Saiyan; if you weren't able to prove yourself strong enough to survive, you would die and not add such weakness to the gene pool. Still, that would result in pretty much the extinction of their entire species as no infant, Saiyan or not, could survive such a thing. As such, the fledgling Saiyan training program was developed. In normal space travel, the Saiyan would be put into stasis but in the case of infants, the gas put them in a state that forced them to be semi-conscious but unable to move much, during which the program would commence. The Saiyan cubs would be able to fiddle around just enough that they could develop further motor control but would be unable to break free or stop the program. Meanwhile the program would be demonstrating various fighting techniques, teaching about Sayina culture, and explaining the importance of purging. This also had the added bonus of causing the infant Saiyan's frustration over being trapped and unable to move for months at a time to be downright explosive once they were finally let out of the pod. The Oozaru form had nothing on a truly pent up Saiyan toddler looking for a target in which to sate their anger.
Raditz adjusted the controls on his brother's pod. Kakarot didn't need motor control training so he could just use the paralyzing gas to the full effect; the pod was in pretty bad shape so even with Kakarot's measly power level, he wasn't certain that he wouldn't break out of it by sheer force if need be. Raditz felt a little bit bad about using such an infantile technique on his own brother but he shoved that emotion down, he did not need weakness right now. Raditz had promised their mother that he would take care of him, and this was the best way. Adjusting the program, Raditz had the AI voice add some extra information based off what he learned about his brother. He really hoped that his brother would just kill the people then be open to learning about their race, embracing his heritage, slaughtering the rest of the earth's population and so on, but Raditz sincerely doubted it and figured some extra insurance wouldn't hurt. As if to immediately confirm his doubts, Raditz scouter went off, announcing a higher approaching power level.
Turning, Raditz looked up to the sky to see his stubborn brother heading towards him riding on a… cloud!?
"How the hell did you find me!?" He yelled up to him, "And what are you doing on that thing!?"
"I followed your ki! Now where's my son!?"
"I don't know what that is." Raditz stared blankly at Kakarot, he would need to ask him some follow up questions about whatever this 'ki' was; if it could track someone around the planet, it would be incredibly useful, "And as for your son, I sent him to get training to be a proper Saiyan. If you can manage your training, we'll meet him at the next purge location."
"What!? But you said if I'd killed 100 people, you'd give him back!"
"First off: I never said that. I said I'd let you see him again; at no point did I agree to give him back. You've utterly failed as a parent so I had to give him to someone else until you can manage his training better. Second: have you killed 100 earthlings yet? Somehow, I doubt it."
"I refuse!" Kararot glared at him, "I would rather die than be like you!"
"Very well then." Raditz sighed, "I guess we'll do this the hard way."
Flickering out of sight for just a second, Raditz appeared right next to Goku. Goku, having had experience with this technique from the beach, was prepared to block the first hit and even the second hit but Raditz simply did not let up. Raditz's hits came in short succession, each one targeting various points on Goku's torso while avoiding vital areas but preventing any retaliation. Shortly, Raditz managed to get a solid knee to Goku's left kidney followed by a chop to the back of his neck that brought him to his knees.
"Honestly, brother. I don't know why you bothered. If I hadn't promised our mother to protect you, I'd have just killed you and been done with it. But of course, you have to be stubborn." Raditz stood above him, glaring down, "Now, what is your name?"
"Son… Goku…" choked out Kakarot.
"Wrong!" Raditz kicked Kakarot in the stomach, propelling him into a tree nearer to the pod, "Your name is Kakarot, and you are a Saiyan. Now try again: who are you?"
"Son Goku, earthing." His brother glared at him from the ground, spitting out a small amount of blood.
"You really are hopeless." Raditz sighed, "Well, I hate to do this but you are leaving me no choice. Remember that you forced my hand."
Sidestepping over to his estranged brother, Raditz smacked him across the face to stun him then, lifting his barely conscious brother, Raditz hoisted him into the pod. After pumping some of the pumped some of the paralyzing gas directly into his face, Raditz strapped him into the seat. Tapping a couple of the buttons, Raditz activated the adjusted fledgling Saiyan training program.
"Enjoy the training Kakarot and please know that it was your own stupidity that made it come to this." He informed his brother he closed the pod, "I think 48 hours should be a good starting point."

Elsewhere on earth, Bulma managed to successfully make it to the Lookout. On one hand, it was absolutely incredible to see: The home of the Guardian of Earth. A place unseen by the majority of humans. A place where reality was just a little bit different. On the other hand, the fact that she, a non-warrior, was able to travel there in a plane was very much not a good thing.
"Hello?" Bulma called out, "I was sent here by the warrior of earth? I'm looking for Kami? Please still be alive."
"I am sorry to tell you this." A dark blob appeared behind Bulma, "But Piccolo was killed and so Kami has since left this realm."
"OH MY GOD!" Shouted Bulma, jumping at the sudden presence, "Who are you!?"
"I am not God." Answered the man-like being, "I am Mr. Popo. I was the attendant of Kami."
"I am sorry for your loss." Managed Bulma, catching her breath.
"I believe you may be able to help me and restore Kami." Mr. Popo stared distantly at the bluenette, "Come with me."
Leading Bulma, the two stepped onto a carpet and suddenly were transported onto a cold, windy desert with steep rocks.
"Where are we!?"
"Yunzabit Heights" Answered Mr. Popo as he began walking though the canyon, "Please follow me."
"Yunzabit Heights!? That's on the other side of the world!" gasped Bulma, "Did we just teleport!? Hey wait up!"
Walking around a bend Bulma suddenly saw what Mr. Popo had brought her here, halfway across the world, to see. A massive white thing covered in moss with an organic sculpted appearance, protruding spikes, and huge bulbous windows sat in the middle of the field. Stepping forward to the structure, Bulma placed her hand on it and was surprised to feel that it was not metal.
"About a hundred years ago, Kami told me a very strange story. He spent his childhood here and when I asked him why he would choose here of all places, he said he didn't know why. I asked him if he lived with his parents and he said no but that they left a note telling him to wait and that they were coming back. He said he waited for them for nearly 30 years but nobody ever came so he left as it is very cold and there's not much resources around here." Mr. Popo looked at the structure, "He told me about his 'house' but I wonder if that's not a spaceship that originally brought him to this planet. If so, it might be able to go to him home world and use those dragon balls to restore him."
"What!?" Bulma stared at the other being in confusion, she was really having to adjust her world view today. To imagine, 24 hours ago her biggest issue was dealing with the breakup of her first long-term relationship.
"He said it opened when he said a certain word: piccolo."
At the mention of the name, the bottom part of the structure between the 'legs' suddenly unattached itself and floated carefully onto the ground.
Mr. Popo and Bulma stepped onto the platform and, after saying the codeword again, the platform levitated itself up, along with the passengers into the building. Looking around, Bulma was very alarmed to be in some sort of mission control center. In the center of the room was a large chair and surrounding it were numerous control panels. Running over, Bulma began examining the surfaces but couldn't find any buttons.
"Mr. Popo, do you know any other words from Kami's native language?" Asked Bulma, if the term Piccolo had activated the door, maybe other such commands would activate the ship as well.
Between the two of them, Bulma and Mr. Popo were able to figure out a series of commands that could control the ship and, after managing to get into the ships mainframe, Bulma was successfully able to find the original coordinates of Kami's home planet, a place called Namak. After doing a thorough examination of the ship, Bulma was confident they could prepare it for a long-term journey within about two weeks.
Pulling out her phone, she texted Krillin a quick summary of her findings: "Kami is dead, Piccolo was killed, probably by Goku's brother so no more dragon balls. Kami and Piccolo were aliens so the plan is to use their spaceship to go to their home planet and use the dragon balls there to restore them. I'll get everything prepped but the actual trip is going to be for multiple months. Any luck finding Goku?"
Krillin responded with: "… No luck finding Goku. Would like a deeper discussion about the spaceship and aliens though."
