Age 763
As the months went by, Yamcha, Tien, and Chiaotzu were brought back to life with the help of Namek's Dragon Balls.
Everyone had found out that Goku was alive and had defeated Frieza. But he was stranded on a different planet, training while his space pod got repaired, and refused to come back to Earth.
Age 764
Almost a whole year has passed, and
Bulma's and Goku's third child is born. Bikini is almost a spitting image of Gine. Just like her oldest brother, she was born with spiky black hair and eyes and a brown tail.
All Namekians had left Earth after wishing for a new Namek. Now, every Z fighter, including Vegeta, was standing in shock in the middle of a desert, watching as a mysterious Super Saiyan boy cut Frieza in half straight down and easily took out Frieza's father, King Cold, like they were nothing.
The mysterious boy asked to follow him, as Goku would arrive within the hour. As they had waited nearly an hour, Roku noticed the blue-haired boy kept staring at him and his mother frequently.
Upon Goku's arrival, the enigmatic boy approached him. As Goku and the boy disclose his identity. He then inquires of Goku about Roku's identity and why Bulma possessed a Saiyan tail.
Goku told Trunks why Bulma had a tail due to the wish she made when they first met. And that Roku was his and Bulma's second-born son. That confused Trunks a lot, realizing he was in a different timeline.
As Trunks left in his time machine, Goku approached everyone else. When they asked him what the boy wanted and who he was, Goku struggled to explain. Roku then spoke, seeing that Goku was worried.
"Don't worry, Father, I won't say anything that could cause trouble for him. But if you think about it, you have nothing to worry about since there are many changes already."
Bulma then places a hand on Roku's shoulder.
"Hey, Roku, you heard what your dad and that boy talked about from here?"
"No, I don't have that good of a hearing, but I have excellent eyesight and could read both dad's and that guy's lips from here. That guy came from the future. He came to warn us that in three years, two androids will appear and cause chaos in the world. These androids kill most of us in the future that guy came from."
After Roku finished talking, everyone agreed to train for the next three years and meet up at Amenbo Island, nine miles south of South City.
As everyone left, Roku stopped his parents and Gohan.
"There was one more thing that guy said. He said that our dad died in the future from a heart virus and gave him the medication created after his death. We all should make sure Dad takes his medication because he will forget."
His mother and older brother agreed and were ready to fly back home, but Goku stopped them. Goku requests that Gohan and Roku train with Piccolo for at least a month. That he and their mother need a lot of time to catch up.

Roku "Age 10, Power Level after Zenkai Bost from revival After Namek 10,500,000."
Gohan "Age 11.5, Power Level After Namek 5,700,000"
It's been three years since Goku's return from Planet Yardrat. During those three years, Goku and his sons trained constantly in a Gravity room built by Bulma, Dr Brief, and Roku. Within the last six months, Bulma gave birth to Trunks. That's something Goku was trying to achieve since he felt somewhat bad about Future Trunks not existing due to Bulma not ending up with Vegeta. Goku dedicated himself to spending every possible moment with Bulma, often multiple times a day, until she became pregnant. After that, he could finally kick back and focus on his training without a care.
Everything went the same: Goku still got sick, and Yamcha got fisted by Android 20. Gohan and Roku took Goku to their home. Vegeta was able to finish off Android 19 in his Super Saiyan form.
Android 20 or Dr. Gero was killed by Android 17 after being released with Android 18 and Android 16. Vegeta eventually gets his ass kicked by 18, which leaves Vegeta confused. He was embarrassed that a woman had beaten him at his strongest, but also excited that he had found the perfect woman who was able to do so.
Cell finally made his appearance and went on a human buffet feeding spree. Kami finally penetrated and went inside Piccolo's to finally become one again.
As Goku finally fully recovered from his Heart disease, every fighter went to meet at the Look Out and train in the Hyperbolic Time Chamber. Goku trained with Gohan, and Roku decided to go in with Piccolo. The time came when Goku and Gohan emerged from the Hyperbolic Time Chamber as Super Saiyan. It was Piccolo and Roku's time to go in, but tragedy struck, and Roku fell to the ground, holding his chest and struggling to breathe. Everyone quickly realized what was happening to Roku. Goku uses his Instant Transmission technique to appear beside Bulma with Roku in his arms.
Cell announces his tournament is happening in one week to the world.

When Roku recovered, he realized everyone had left to fight Cell. He then rushes to where the fighting is currently taking place. When he arrived, the last thing Roku saw was his father placing his hand on an obese second-form Cell, and then both Goku and Cell disappeared in the blink of an eye.
Gohan and the rest of the fighters felt a power skyrocket in the air, and as they looked up, they saw it was Roku. Lightning began to fall around Roku; his anger was running out of control, and the skies started to darken as Lightning fell upon Roku, covering him in light. As the light slowly disappeared, Roku had finally transformed into a Super Saiyan. Still, the hair color was different; it wasn't the usual golden blonde color that Gohan, Goku, or Vegeta had. Roku was a yellowish neon green.
While everyone was distracted looking at Roku, they all failed to realize that Cell had returned and was stronger than before.
Perfect form Cell then fired a ki beam toward Trunks, but at the last minute, Roku appeared before Trunks and slapped away the ki blast from Cell that would have killed Trunks if it had hit him.
Roku then flew off at top speed toward Cell as he explained how he survived, but was interrupted by Roku with a left hook to the body of Cell. Gohan appears next to Roku and lands an uppercut on Cell's jaw, sending him flying to the sky.
Both brothers looked at each other and nodded. Gohan and Roku both stand with their feet shoulder-width apart, slightly bending their knees to maintain balance. Join their palms in a cupped formation, ensuring a slight space between them. With their elbows tucked in and fingers loose, they focused intensely, gathering a significant amount of ki between their hands. In one swift and forceful motion, they thrust their hands forward, releasing their family signature finishing move, the Kamehameha wave, at Cell, where Cell suffered complete annihilation, vanishing without any remnants of itself to auto-reemerge.
Everyone then decided to head toward Capsule Corp, as Bulma had gathered the Dragon Balls days before Cell's tournament. The first wish after summoning Shenron is to bring everyone back to life whom the androids and Cell had killed. The second wish was to get Goku back from the dead. But he refused, stating that he was a magnet for trouble for the entire Earth. After hearing what Goku said, Bulma stepped in front of everyone.
"The hell you will stay dead in the other world. If you are putting the Earth in danger, you must fix it. We will fix it as a family, plus you got me pregnant again, idiot. You're not leaving me behind to raise three Saiyan toddlers. Plus, Gohan and Roku still need their father. So get your ass back to the world of the living, mister."
Everyone remained quiet after Bulma's outburst. Sharon, not wanting to anger a pregnant woman, forces Goku to return, and then he disappears into the sky with all of the dragon balls.

Seven years have passed since the attacks from the Androids and the bio-android called Cell. Bulma gave birth to Goten, a spitting image of Goku. Goten just turned seven, and to the surprise of everyone, he can go Super Saiyan and does as well as Trunks. Becoming the youngest to achieve Super Saiyan.
Gohan, now eighteen, about to be nineteen soon, decided to attend high school and try to have a somewhat normal life without having to save the world every time. He only trains with Roku and Goku about one or two days of the week sometimes. But it remains true of becoming a Scholar.
Roku, on the other hand, didn't want to go to school, so Bulma hired tutors to homeschool him. By age eleven, he finished High school, and by age fourteen, he had finished college with several degrees in physics and engineering, biology, and botany. Now, sixteen years ago, Roku spent part-time working alongside his mother and grandfather in Capsule Corp, and the rest of the time when he was not working, he trained all day with his little brother, Trunks, and Goten, and his father, Goku. Roku also decided to leave Earth and train on Planet Yardrat for almost two years. Learning Spirit Control, Forced Spirit Fission, Healing, Instant Transmission, Multi-Form, and Magic Materialization.
The 25th Tenka-Ichi Budoukai World Martial Arts Tournament arrived, and most Z fighters decided to join the tournament.
During one of the fights, Gohan's new girlfriend, Videl, was heavily beaten by Spopovich, angering Gohan. A mysterious fighter by the name of Shin approached both Goku and Roku. He had purple skin with a white mohawk and wore a blue coat with red lining, an orange waist cloak, a pale teal long-sleeved shirt with matching pants, and red boots. He also had on a pair of yellow earrings.
Shin revealed that he was the Supreme Kai, having come down to Earth on a crucial mission to stop the revival of a being known as Buu. He suggests we avoid getting involved in the imminent fight between Gohan and his assistant, Kibito. No matter what, we must let Gohan's power be absorbed by Babidi's minions and carefully track them back to their lair.
As Babidi's minions took Gohan's power, a sense of foreboding enveloped Shin. He had completely misjudged the incredible power that Gohan held within him. Roku passed Gohan a Senzu bean, and in an instant, Gohan's power surged back to life after he consumed the Senzu bean. Goku, Gohan, Roku, Piccolo, and Vegeta took off and followed Babidi's minions, Spopovich and Yamu.
As they all flew in the air, Roku increased his speed and approached Shin.
"Hey, Shin, so who is this Buu that you are afraid of so much?"
"Buu is not a person you can talk to. He is a monster. Millions of years ago, I lived in the Sacred World of the Kai with four other Kais. I was the youngest of the Supreme Kai and the weakest. When Buu appeared, that monster killed both the West and the North Kai. But he didn't stop there, and then Buu turned his attention to South Supreme Kai and ate him. Buu then tried to kill me next, but thanks to Grand Supreme Kai, he was eventually absorbed by Buu moments later."
An idea came to Roku after hearing Shin's story.
"Could it be that this Grand Supreme Kai character is still alive inside Buu? If that's the case, I might be able to help him using a technique I learned during my training with the people of planet Yardrat."
Shin began to think as he continued to fly about what Roku just said.
"I would love for you to save Grand Supreme Kai and see him one more time, but releasing him would revert Buu's transformation to his primal self. He would be uncomfortable and unstoppable."
As they reach Babidi's lair, the Z fighters, joined by Shin and Kibito, engage in an epic showdown with his minions and decisively defeat them. Alas, they had come just a moment too late. Buu broke free from prison thanks to all of Gohan's stolen energy. During the battle against Buu, Roku unleashed a colossal ki blast that pierced through Buu's form effortlessly, striking Babidi, who stood unsuspectingly behind him, resulting in his swift demise.
Shin advises everyone to stop because Buu is too much for everyone. As she devised a plan, Roku convinced Buu not to attack anyone on Earth, and in return, Roku gave Buu his stash of junk food he had stored in his capsule.
Piccolo, Krillin, Trunks, and Goten stayed behind to watch Buu in case anything happened. Goku and Vegeta went to the Lookout and trained in the Hyperbolic Time Chamber. As for Gohan and Roku, they went with Shin to the Secret Planet of the Kias.
Gohan proudly pulled the Z sword from the ground and began his training. Roku threw a barrage of massive boulders toward Gohan, who deftly cut them in two with his sword, showcasing his incredible skill. Shin noticed that and began to forge a dark metallic cube. He declared that it was the strongest mineral in the entire cosmos. Gohan unleashed a mighty swing of his sword, aiming to cleave the cube in two, but the blade shattered dramatically upon impact.
As the Z sword shattered, a fresh voice echoed, capturing everyone's attention. It was a more mature version of Kai. He declared himself the Supreme Kai from fifteen generations past, sealed within the sword eons ago by a slothful and dreadful deity.
After deciding that Gohan should be the one to have his sleeping power awakened by the old Supreme Kai, Goku and Roku chose to return to Earth to keep an eye on Buu, preferring not to spend 25 hours watching Gohan stand still, doing nothing. Upon returning to Earth, Roku devised a strategy to confront Buu.
Twenty-five hours had elapsed, indicating that Gohan's ritual was nearing its conclusion. Goku and Roku assembled at the location where Vegeta, Piccolo, Trunks, and Goten were present. He subsequently outlined his plan to all present. Goku asks him if that was his intention and why he had Gohan undergo the ritual. All three have joined forces to confront Buu. Roku gazes at Goku and states that Gohan is the one who needs it the most. In recent years, he has ceased training. There may come a time when an even more powerful opponent appears, and I believe Gohan will be the first to fall.
Roku soared into the sky, determination in his eyes, as he rushed toward Buu after sharing his strategy with his father. Goku nodded in agreement with Roku's strategy, remaining in place until the moment arrived to take action. Roku unleashed a powerful attack on an unsuspecting Buu. Roku appeared before Buu, ascending to Super Saiyan form and unleashing a flurry of powerful strikes against Buu. As Roku unleashed a flurry of powerful strikes, he was meticulously gearing up to execute the technique he had mastered on the distant planet of Yardrat. With a crucial attack, Roku unleashed the Forced Spirit Fission on Buu, triggering a dramatic split in his form. In an unexpected twist, Buu separated and unleashed two entities.
With an energetic gaze, Goku shot into the sky towards the unconscious bodies and landed on them, effortlessly lifting the two unconscious figures as if they were weightless. But before he leaves, Goku gazes at his son and shouts.
"Roku, I'm taking my leave now. I'll let Gohan and Kias know of your plan."
" Okay, Dad, I'll see you guys soon."
Goku then used his Instant Transmission to appear next to the Kias and Gohan.
"I can't believe it, Goku!" The ones you have with you are they the Grand Supreme Kai and the South Supreme Kai? But how could that even happen?
"For that, you owe a debt of gratitude to Roku. He is the one who successfully separated them from Buu using his incredible Forced Spirit Fission technique, a skill he honed during his intense training in Yardrat. That brings to mind, hey Gohan, is your power awakening ritual over yet?"
"Yes, why do you ask, Dad?"
"Well, your brother is coming here with Buu any moment using his teleportation. We'll go to Roku when he arrives using my teleportation, and take out Buu for good once and for all. So be ready and power up all the way. We'll be taking him out in one combined attack, the three of us."
"Okay, sounds good, Dad."
Roku, witnessing his father Ki disappear from Earth and appear in the Kais' realm, grinned as he captured Buu, who was still reverting to his original state. He then vanished in a flash, appearing in the hidden realm of Kai, touching down a bit away from Goku, Gohan, Shin, and the ancient Kai.
Roku delivered a powerful kick to Buu with all his strength. He ascended into the sky, channeling his energy and unveiling his new form, Super Saiyan 2. Moments later, Goku materialized beside Roku along with Gohan. Upon arrival, they were both taken aback to find Roku in Super Saiyan 2 form. Goku, with a smile and beaming with confidence, focuses his Ki and unveils his latest transformation, Super Saiyan 3. Gohan taps into his full potential without undergoing a Super Saiyan transformation. His new power was equal to or even exceeded Goku's Super Saiyan 3.
As Goku and his sons began to channel their Ki energy for the secret legendary technique of the Turtle Hermit School of Martial Arts, the Kamehameha wave. As the creature known as Buu reverted to its original and authentic self, Goku, Gohan, and Roku unleashed the unstoppable blue wave of energy, obliterating Kid Buu upon impact, leaving no opportunity for escape or evasion.
Joy radiated from everyone as they showed their victory over the formidable Kid Buu and the successful rescue of the South Supreme Kai and the Grand Supreme Kai.
"Hey guys, don't you think this was too much overboard?"
"What do you mean, son?"
"You know, we're combining our attacks all in one. Overpowering Buu easily."
"No, Gohan, it was a must. Buu can regenerate himself. So, no, I think we went overboard with all our powers. Now, we must make sure Buu is dead."
" I guess you're right, Roku."
Goku thought of an idea and vanished into thin air, employing his Instant Transmission technique. In the blink of an eye, Goku was back, grinning from ear to ear. Roku narrowed his eyes after seeing his dad smiling.
"Where did you go, Dad?"
"Nowhere, in particular, Gohan. I just paid a visit to my old friend, King Yama. He confirmed Buu's death."
Roku felt uneasy. Something was wrong, but he couldn't think what.
"What did you do, Father?"
"What didn't do anything, trust me."
Roku just sighted. The only thing he wanted to do was to return home and eat.
Age 774
Several weeks have passed, and Roku awoke early in the morning and showered. He went to the Capsule Corp labs to collaborate with his mother and grandfather. Bulma and her father had been collaborating on a Reactor designed to provide free electricity to impoverished villages around the globe for over a year. After countless grueling days and intense lab hours, Roku emerged from the Capsule Corp facilities, walking towards his room to shower, cleanse himself, and recharge for the next challenge. He carefully mapped out his day, beginning with the moment the arc reactor powered up, then, after that, he would fly over to the sacred place, Mount Paozu, at their family vacation home for several days of intense training, thrilling dinosaur tail hunting, and well-deserved downtime.
After Roku had freshened up, an explanation occurred that came from the Capsule Corp labs, and it rattled the entire building. Roku had only his Gi pants on when he used his Instant Transmission technique and appeared outside the labs where his grandfather, Dr. Brief, was with some scientists and interns.
"Grandpa, what happened?
"Roku, we tried to turn on the reactor, and it was working for the first few minutes, then it exploded."
Dr. Brief had a worried look on his face as he stared toward the laboratory.
"Bulma is still in there. We need to get her to safety."
"Mother is still in there."
Roku rushed into the laboratory without a moment's pause. As he took his initial action, he observed a dark hole where the nuclear reactor had been, drawing in everything around it. Bulma's unconscious body was hurtling toward the black hole, on the brink of being consumed by its immense gravity. Roku hurriedly approached and clutched his mother, aware that his father, sensing his ki, was just behind him. Roku threw his mother's body to his father, saving her from being drawn into the black hole. In the end, Bulma was safe, but sadly, Roku fell into the swirling abyss, its immense force closing immediately behind him as he vanished into the unknown.
