The Z Saga

After getting married, Goku and Chichi had a wondrous honeymoon when they were consummating their love on their first night together.

After a few days, Chichi suddenly grew a tail and went through a dragon-wish-induced transformation, becoming a pure-blooded Saiyan in the process.

Strangely enough, Chichi didn't seem to mind. She felt stronger than ever before and even got more ferocious in bed.

They spent a few weeks together and continued to mate like animals.

After a few more days had passed, Goku decided to take Chichi to go see Bulma.

Thanks to being resurrected at the prospect of seeing his great-grandchild, Grandpa Gohan was around for Goku's marriage.

When he finally saw Chi-Chi and Goku again, the elder informed Goku that girls growing tails after doing the deed isn't normal.

Goku began to worry about Chichi's health. However, Grandpa Gohan was able to calm him down as he said, "It might not necessarily be a bad thing. How about you head over to the smart girl Bulma's house and get her a checkup for Chi-Chi?"

The next thing he knew, Goku was sitting down in Dr. Brief's lab when Bulma came wearing a lab coat, carrying a clipboard with some papers attached to them.

Chichi's face was bright red and showed a happy expression.

"Congratulations Goku, you're going to be a father," Bulma said with a jealous grin.

Goku smiled and jumped up in joy, his eyes widened and his hands wrapped around Chi-Chi's waist, gently lifting her as if he were worried about using too much strength.

Goku then sat her down and placed his ear on her stomach, "Really!? I'm going to be a dad? Grandpa says you can hear the heartbeat."

Bulma sighed and let out a genuinely happy expression, "Yes, Goku, Chichi is pregnant, and it takes a while for the heart to form."

Goku was shaking with nerves when he asked, "Then about Chichi's...condition?"

"Well, she's perfectly healthy, the only difference seems that her genetic code has somehow added an entirely new layer of genomes, this isn't a mutation rather a transformation," Bulma said reading off her findings.

"So, she's okay!?" Goku asked again.

"Better than okay, she's more than human now. Her blood shares a few similar markers to your own," Bulma said scratching her head wondering how this was possible.

Goku hugged her and shouted, "Thank you Bulma! I don't know how to repay you!"

"All right let me down! You're welcome." Goku let her go.

As she fixed her hair, Bulma thought of something and said, "If you want to thank me, you could introduce me to that Yamcha guy Krillin trains with."

Goku rubbed the back of his head, "I don't know Bulma, that guy is literally afraid of women, he won't go near them."

Bulma sighed, "I need a boyfriend, I've been couped up in dad's lab too long."

"Hah! You love it!" Dr. Briefs shouted in the distance.

The tech Vegeta left them to keep them quite busy, however, Bulma had all but forgotten Vegeta, and had almost no idea that he was responsible for all her father's new projects. She just assumed it was something her father made.

Bulma smiled at her father's truthful accusation, "Yeah, I do!"

Turning back to Goku, Bulma took on a serious expression and said, "You should give me a call when he is about to be born, just in case there are any complications."

Goku nodded his head and thanked her again before leaving. After returning home, the timeline continued on like normal until Gohan had been born.

Another difference was Bulma was there and helped them choose the name.

As Goku and Chichi were trying to think of one, she saw how much Gohan got along with his Grandpa.

"How about Gohan Jr," Bulma said with a smile on her face.

The Ox-King smiled and said, "It would be an honor!"

Baby Gohan laughed at the name, Goku seeing this picked him up and said, "Do you like that huh? Gohan!"

"Ahahah!" Baby Gohan laughed.

"I guess it's decided then," Chichi said with a loving smile on her face.

The years passed and Gohan turned 5. Although he had plans to be a scholar, he often snuck off to train with his grandpa. After hearing his father was the strongest person on the planet, his Saiyan blood began to boil at the prospect of surpassing him.

Gohan loved studying, and his mother, but aspired to be strong like his father, even if that meant going against his mother's wishes.

So, not even Chichi could stop him from learning the basics of martial arts. Grandpa Gohan enjoyed his time with his grandchild and even made a game of sneaking around Chichi to train.

Goku eventually received a call from Krillin who set up a party to meet up, this time Chichi came as well. While this was all happening, a brainwashed Turles landed on Earth.

Because of his encounter with the mysterious purple man, Turles never discovered the Tree of Might, and his power stagnated at 1,700.

After landing on earth he used his scouter and located Piccolo, like the original timeline, Turles said, "A Nemekian? What's one doing way out here?"

The two were about to fight it out when his scouter beeped, "Oh so there you are? You're a lucky one, Green-Man, you get to live today."

As he turned around, Turles launched a sneak attack sending a blast out at Piccolo, not caring whether or not he was dead.

Laughing, Turles flew off towards Kame House Island, unaware that what he killed was one of Piccolo's split bodies.

When he arrived people were shocked at the resemblance between him and Goku.

Krillin got too close to his tail, and as a result, was sent flying into the side of the house and while Turles said, "Of course there is a resemblance, I am his uncle after all."

"But you're too young!" Bulma shouted as she hid inside the house.

"Saiyans do not age until we grow very old, we keep our youthful appearance as long as we continue to train and fight." Turles looked to Goku and said, "Now are you going to join me Kakarot, or am I going to have to get rough with you?"

"Humph! I'm Goku, not this, Kakarot! I don't care if I am a Saiyan, I won't help you kill the people of his world."

Goku raised his fist to fight, but all of a sudden, Turles moved faster than he could see and punched Goku in the gut so hard that it caused him to keel over and barf up blood and saliva.

Turles then grabbed Gohan and slapped Chichi away enraging Goku and Gohan.

Both their energies flared, making Turles smile, "Interesting!" He said looking at Gohan's power.

"Power level of 1,100." Grabbing Gohan's tail, all of infant Sayian's fight left him as his power level dropped down to 300, and you can hide your Power Level, 521...so weak."

(Author Note: Goku still has his tail so I had to decide how much of a boost it gives, so I chose something modest, it gives them a quarter of their full power as a bonus, Goku's PL was 417 at the Raditz Saga, so with a 1.25 Times Boost, Goku's power makes sense.)

Holding his finger up to Gohan's head and charging up his Ki, Turles smiled and said, "You have one week to kill all the Earthlings on this planet. If you fail your son will pay the price."

Goku's temper dropped, he gripped his fist to the point blood dripped from his palm.

As he watched his son being carried off by the threat of death, Goku quickly went to pick up Chichi and pulled out his last 2 Senzu Beans.

After feeding them to his wife, and Krillin, he felt his wife's power surge a bit.

Chichi actually got a Zenkai boost and got a little stronger, but not by much, her power went from 145 to 380.

Seeing how the situation was going, Piccolo finally made his appearance. Since Krillin was all healed up, and the bald martial artist knew Bulma was still single, he tried to impress her by shaking off his fear and offering to go along as well.

"Good, we'll take all the help we can get." Goku paused, then looked to his wife, "Chichi, I'll bring Gohan back! I promise."

Chichi was still crying when she nodded her head and felt Goku hug her.

"If you're done now, I'd like to get my revenge!" Piccolo said with a more than unpleased expression.

Goku sighed and called his Nimbus. Hopping onto it, Krillin jumped on his shoulders and said, "Sorry Goku, I can't stand on it and want to preserve my energy."

"Just hold on tight!" Goku said as they took off.

After a few minutes of flying, they settled on the idea of grabbing his tail, "Let's just hope he hasn't trained out that weakness yet," Krillin said as he thought of a plan.

"How about we Solar Flare him then grab his tail," Krillin said placing his finger up.

"Worth a shot," Goku said as they finally reached their destination.

Goku, Krillin, and Piccolo jumped into combat without hesitating.

Gohan was unconscious, and inside Turles's Space Pod, being a was a good distance away from the fight.

Once Goku saw that his son was alive, he clenched his fist at Raditz and demanded that he hand over his son.

Krillin sat back and waited for the perfect chance to use the Solar Flare technique, while Piccolo and Goku teamed up to take down Turles.

The three went back and forward, and it all played out similarly to the original canon. Right up until Goku charged up a full-powered Super Kamehameha and chased Turles with it.

The moment he deflected it, Krillin popped out and used the Solar Flare to blind Turles.

As the Possessed Saiyan lost his sight, he swung out wildly hitting Krillin and sending him flying into a tree, and knocking him out with severe injuries.

Goku grabbed his tail and held him down. Just like how the original event played out, Goku let go after hearing Turles beg for forgiveness and play the, I'm your Uncle Card.

After the two ended up taking another beating, Gohan had snapped and broke out of the Space Pod, this time his Power Level was 2,100.

With a flying head but, he smashed into Turles while shouting, "Don't hurt my daddy!"

Turles was severely weakened from the blow. Goku took the chance to hold him in a full-body grapple, and Picciolo took the chance to finish charging his special beam cannon.

**************

Years earlier on Namek.

Vegeta continued to train the two new Saiyans that he had revived. After the first two years, Bardock and Gine had grown by leaps and bounds. The Timeless Training Grounds truly helped them progress quickly.

Vegeta had ordered Napa and Raditz to take it easy and build up their S cells, only then would they have a good chance of unlocking the Super Saiyan form.

Vegeta made sure to take it easy with his training as well. However, during the final year, Vegeta brutalized both Bardock and Gine every day.

There wasn't a single second that they weren't at death's door, and every time they felt the cold touch of Death's embrace, Vegeta healed them up and started the process all over again.

Once they were able to defend themselves, Napa and Raditz took over their training while Vegeta walked off to focus on becoming a Super Saiyan.

He focused on the things that he cared about, Bulma, his future children, and his friends and rivals, then he imaged his worst fears taking them from him. Then, in popped the image of Moro, the one who would defeat both Goku and Vegeta after the tournament of Power.

The Training Grounds began to alter Vegeta's state of mind, causing it to go berserk with terrifying images and experiences.

Everyone stopped their training because they could feel Vegeta's Power Level skyrocketing. His aura pierced into the sky as he focused all of the energy into his spine.

As he felt his tail tingle, a golden aura erupted as Vegeta let out a long-winded scream, his hair turned to gold, and his eyes turned greenish-blue.

Vegeta smiled and felt the sheer power of the first Super Saiyan form flowing through him.

"Vegeta? That form?" Bardock managed to speak out while the rest mumbled while pointing at Vegeta.

"I have ascended to the first plateau, I, Vegeta, King of all Saiyans have become a Super Saiyan at long last!" Vegeta felt that the realm was helping him acclimate to the new form.

The Saiyan Training Grounds exuded a strange kind of invisible pressure that could keep the transformation from dispelling due to lack of focus, allowing the practitioner to sustain the transformation until they get used to it.

Vegeta powered down and turned it back on, over and over again, he repeated this until he could finally do it at will.

"What did you mean by the first step?" Raditz asked.

"Super Saiyan isn't our final form. I feel a higher form of it exists beyond the Super Saiyan State, a Super Saiyan 2, maybe even a third and a fourth."

Everyone was shocked at the idea of furthering the immense power they already felt.

"It appears that the Super Saiyan transformation carries a 50 times multiplier to all my abilities," Vegeta informed as he waved his hand, causing a windstorm to pass over the terrain.

"Does this mean you can defeat Frieza now?" Napa asked.

Vegeta grinned and answered, "With ease!"

He then turned to the sky and said, "But for now, it's time to go to earth and train up Kakkorot."

Bardock, Gine, and Raditz smiled and thanked Vegeta with a saute.

Nodding his head in approval, the Saiyans left the Training Grounds. However, before they left, Vegeta took the two new Saiyans to Guru to unlock their potential.

Guru's body had slimmed down but was still large, he stood at 8 feet tall and sat in his chair with renewed vigor.

After getting Bardock's and Gine's hidden potential unearthed, Vegeta threw them into the Training Grounds again and let them continue to train by themselves for another 2 years inside, and only 2 days outside.

Vegeta decided on what he would wish for while he waited.
