Year 762, December 24th
From the time Gohan found herself in a tree back on Earth along with Bulma and all the newly resurrected Namekians, a lot had happened. Goku had won the battle. The planet Namek had blown up along with her father and luckily Frieza. Gohan felt sad but knew with the Nemekian Dragon balls he wouldn't stay dead for nearly as long this time. Then Vegeta alive and being a Cocky S.O.B. as always tried to assert dominance over Gohan and the rest, she wouldn't stand for it. The resulting fight had both giving and receiving damage, almost even in power, it was Vegeta's expertise and more advanced knowledge of fighting that gave him the edge and beat Gohan, barely, if it wasn't for Piccolo stepping to stop the fight before it got out of control as Gohan would not stand down, and the spectators were afraid it would be a fight to the death. Not long after that Guru the Eldest Namek died again. The Namekian Dragon balls turned to stone once more, luckily the new Elder could resurrect them and in 1 Nemekian year (130 Earth days) they could use them again, in the mean time the Namekians would stay with Bulma at Capsule Corp. When Bulma's father had arrived with a plane big enough for all the Namekians Gohan was reunited with her mother. Once again she was smothered by her mother's love and care.
Year 763, May 20th
Over the first 130 days Gohan spent most of it studying, though she had finished all the homework given to do on the trip before the ship was blown up she couldn't prove it and had to start again. After the things she saw on Namek it was a nice change, like a break from the inevitable battles that seemed to be becoming a regular thing in her life. Finally, the day came when they could summon the Namekian Dragon. Everyone gather in the gardens at Capsule Corp ready to summon the Dragon the first 2 wishes were used to bring Krillin and Goku to the Earth check-in station, where they learnt Goku was still alive the second wish to bring Krillin back to life and Earth, the third was to bring Goku to Earth.
Sadly, Porunga replied it was unable to be done, "the one called Goku does not wish to return, he has unfinished work he needs to attend, he will return in a year or so." Noticing the furious expression on Chi-Chi face he quickly added, "his words not mine." After some confusion and lots of mumbling the dragon demanded they make another wish, it was decided that Yamcha would return first.
During all that Piccolo watched his young student, he could sense her heart breaking even if she tried to hide the emotion on her face her energy screamed it. Piccolo motioned for Gohan to follow him, walking away from the group he placed a hand on Gohan's head, "Ki… uh… Gohan what is wrong? And don't try to deny it I can sense that something is."
Tears began to stream down her face unable to stop them. "Daddy wants to come back to us, I can feel it, he wouldn't stay away unless it was really important. I know that. But something or someone is keeping him away." Needing some more comfort than Piccolo was able to muster Gohan buries her face in his leg hugging it tight. Her head barely above his knee, all the Namek can do it awkwardly pat her head till she can stop her crying and school her features. "We were supposed to have time to catch up after being apart for so long…"
Piccolo mentally cursing his rival he was always getting into trouble and trying to help people again. The warrior bent down to look his student in the eyes. "Gohan, how about I come visit you in a day or so, we can talk to your mum about continuing your training? She may be more accepting if we include her in the decision instead of just going off like last time."
After a short pause contemplating what her mentor just said and liking the idea of not having to sneak around to train like she originally thought she would have to do. "You will have to convince her that training wouldn't interfere with my studies."
"Let me worry about that,"
"Thanks Mr. Piccolo, you're the best!" Feeling a lot better Gohan noticed the group starting to disperse knowing her mother would be looking for her soon wanting to leave, Gohan rubbed her eyes and started walking back.
"Gohan! This conversation never happened!" Piccolo called after her.
Looking back the black-haired girl just smiled and continued to walk.
True to his word in the few days since Porunga was summoned Piccolo was knocking on the Son's door, Chi-Chi was tidying up after lunch while Gohan was doing her studies. Running down the stairs to answer the door, as Gohan already knew who it was, she was so happy he kept his word.
Chi-Chi also walked to the door to greet the strange visitor it was his tone used when addressing her daughter that Chi-Chi realized this was a serious visit. "Gohan, I need to speak with your mother, alone." Gohan already knowing what was going to happen agreed after quickly hugging the Namek. Chi-Chi noticed the slight blush on the big green mans face and was still amazed at the friendship her daughter was able to make with this man who was a monster in her eyes for years after the escapades of the WMAT, and if it wasn't for her daughters joy at seeing him she wouldn't even be entertaining the idea of speaking with him, not after he took her daughter from her for a year.
Sitting in the kitchen Piccolo began, not beating around the bush with pleasantries, "I've come to request the continuation of your daughters training, before you object hear me out." Piccolo quickly added making so he was uninterrupted for his speech as he hates giving them. "Gohan has enormous potential and unlimited learning capacity. She needs to keep herself motivated. At the rate she absorbs information it will likely be hard for you to find school work for her in the near future I imagine. Now my form of fighting utilizes the mind and the body. Resulting in better focus and tact. Even if it is only every second day for half a day letting Gohan train with me will be immensely beneficial to her studies." He continued to praise his unique fighting style and how it helped with physical control as well as emotional, the fact Gohan had mastered it already over a year ago Chi-Chi needn't know that. Eventually Chi-Chi conceded and together they designed a schedule that allowed a balance to her life Gohan had only ever dreamed of.
Starting off in the mornings with Meditation followed by Breakfast than an intense spar followed by lunch and studying the rest of the day till dinner and more studying till bed, with the exception of one day a week there was no studying and no training, and she could do whatever she wanted. This schedule continued until the Namek Dragon balls were able to be used once again, gathering all together like last time they summoned Porunga and wished back Chaozu and Tien with he first 2 wishes, the third was to wish all the Nameks to an uninhabited new planet like their old one, this wish was quite the sad moment as the Namekians had grown attached to their Human hosts but did not belong on this planet.
Dende and Gohan had a teary farewell she was losing the first friend she made that was closest to her own age, whom she had gotten to know well over the last 260 days they had been on Earth, but he belonged on Namek with his people and she was here, it was a shame they couldn't write to each other but maybe one day they may get to meet again. With one last hug Dende disappeared from Gohan's grasp disappearing into the air.
The days rolled by and Gohan couldn't be happier, well she could, she could have her whole family here but was okay with waiting, he said we would be back in a year or so, that time was definitely coming. Gohan couldn't wait for the chance to spar with her father and show him how powerful and skilled she had become under Piccolo's tutelage. Not to mention apparently she had made her way to college level science and maths and was surprisingly enjoying it, her mother didn't seem to yell as much anymore either they had all learned to co-exist together and find a good balance, also spending her days off at Capsule Corp helping Bulma and Dr. Briefs with minor things learning as much as she could.
Year 764, August
It seemed like an average day after lunch Gohan was at the kitchen table studying for a change while her mum washed the dishes from lunch when Gohan felt a terrible power that was supposed to be gone enter Earth's atmosphere. When she dropped her pencil, her mother turned around to look at her worried, suddenly Piccolo burst through the door, it wasn't uncommon for him to let himself in over the past year when Gohan was studying as he enjoyed the cold water Chi-Chi had been keeping in the fridge, Chi-Chi didn't mind either after the first few months she got used to it as he didn't eat their food and didn't lounge around her house he only came for the cold water. When Gohan and Piccolo looked at each other, Chi-Chi knew something was wrong.
Gohan hadn't changed from her sparing clothing from this morning, rising from her chair "Mr. Piccolo! That can't be?...!" Piccolo didn't respond only nodded.
"What's wrong dear?" Chi-Chi starting to worry more.
"You remember my story of the evil space tyrant dad fought on Namek?" at the grim nod, Gohan knew her mother hated talking about her daughters horrors on the other planet it hurt her that her daughter had to go through that. "I can feel his energy coming towards the Earth, we have to go."
Gohan could tell her mum wanted to argue with her it didn't matter to her mother that she is one of the strongest on the planet she still saw her as the 6-year-old little girl, thinking she needed to plead her case to go fight while not disobeying her mother Gohan started, "Mothe…"
"Go," Chi-Chi interrupted, anyone could tell she was having an inner battle, but she knew she wouldn't win against her daughters need to protect the world like her father before her. "Be safe and come back okay."
With the blessing Gohan stormed out the house, she heard her mother yell to Piccolo whom was following behind in his usual no rush pace, "Piccolo! Watch over her will you!?"
The stoic warrior paused and turned around to the Martial Artist turned house wife and gave a rare smile and nod in acknowledgement.
By the time Gohan and Piccolo had landed the rest of the group including Vegeta, as well as Bulma were waiting and assessing the situation while trying not to be detected by their scouters as they watched Frieza and what appeared to be his father along with hundreds of minions scoping the area, when out of nowhere a purple haired teenager showed up and eradicated all of Frieza's minions without even breaking a sweat. Followed by him apparently going Super Saiyan if what they could see was any indication, though Gohan and Vegeta were the only ones to of seen a Super Saiyan before, the later was adamantly refusing the possibility of the boy being one as only he and Goku were the last surviving full blooded Saiyans left while the other just stared in awe. With no trouble at all the supposed Super Saiyan diced Frieza into little pieces and blasted him out of existence, followed by a brief encounter with Frieza's father also killing him and destroying their space ship. The next thing Gohan knew the strange boy was back to being purple haired and addressing the group saying he knew where and when Goku would be landing and was heading to the destination if the rest wanted to join. Gohan didn't need to be told twice and was first to take off with the rest reluctantly trailing behind and Vegeta still ranting about how this kid can't be a Saiyan.
Once they landed the stranger popped a refrigerator Capsule and offered everyone drinks, all the adults besides Bulma were reluctant to get one but Gohan was thirsty, it was hot today in the desert. "Is there Orange?" Gohan asked the stranger walking up to him as he is opening a can.
"Wait Gohan, stay back!" Yamcha yells. I flicker of surprise flashes across the newcomers face at that comment as he stands in front of Gohan seemingly blocking her way. All the fighters tense up, even Vegeta.
They look at each other for a few seconds before he hands her his drink, "here, it's the only orange one, you have it."
Gohan ecstatic she gets the orange one as she isn't familiar with any other flavours, her mother doesn't let her have any fizzy drinks, replies a simple "Thank you." Along with a brilliant smile that should be trademarked for the Son members. After the little exchange Bulma and Krillin get drinks too and the rest seems to be just waiting, watching.
They had been sitting around for over an hour with another 2 hours to go, Gohan had caught the strange boy, who refused to tell them his name but seemed nice enough, alternating between staring at her with what seemed to look like confusion and staring at Vegeta with a look of longing, though he was doing a decent job of hiding it most of the time until Vegeta called him out. Gohan also noticed how tense Piccolo was while they waited, when Gohan asked why, he didn't respond.
Finally, as the 3 hours waiting was up everyone arose, that's when Gohan felt her fathers Ki for the first time in over a year. "It's daddy! He's here!" Gohan couldn't contain her excitement any more and ran towards the giant crater that had formed from the landing. Once the dust had settled Goku slowly emerged from pod, as all his friends were cheering he locked eyes with his daughter and shot up to hug her, engulfing her in a hug ignoring all the comments being shouted at him.
"What took you so long daddy?" Gohan mumbled into her father's shoulder.
Goku finally released his daughter and replied addressing the whole group this time, "I'm sorry, I wanted to come back when the dragon asked but the people that rescued me said they had been given instructions to train me and that I could leave when they deemed it ready."
After explaining what happened to Frieza the stranger asks Goku if they can talk alone. Gohan who hadn't let go of her fathers leg after the hug reluctantly let go when her father bends down with a quick pat on the head and a promise not to be too long. No one could hear what was being said except maybe piccolo if his facial expressions Gohan was watching at times were anything to go by, when both the stranger and Goku powered up everyone could clearly see that they were both super Saiyans. There was more talking after their little fight, suddenly dad yelped, and the stranger pointed at him and he fell over. Eventually the conversation was over the stranger just flew away in the other direction, but dad wasn't coming back to us so after seeing Vegeta being first to go over to him Gohan followed and so did the rest.
By the time we got there Vegeta was already demanding to know what was going on, while Goku seemed to be ignoring him and refusing to say. Surprisingly it was Piccolo whom talked first, "On May 12th."
Goku jumped in then asking piccolo to not explain too much after a short argument about us having a right to change our futures Goku relented and explained that in 3 years, 2 Androids were going to attack us and in the fight everyone but Gohan would die. This spurred on more arguments among them, Gohan was only thinking about how can she be strong enough to help, if she is the only one to survive then either she was too weak to help or the androids took pity, either way it wouldn't happen again.
Coming back to the argument her father declared he was going to train vigorously for the upcoming battle. It was up to the others to do so too. "Hey Piccolo, wana come back to ours and help me train?"
"As I already have your wife's permission to train your daughter every morning. I don't see why not."
Gohan thought she saw a dark shadow pass over her father's face before his usual cheery look was back. "Chichi has been letting Gohan train? That's not like her but that's awesome, it won't be so hard to get her to let you train intensely with us then."
"I hope so daddy, but I only get a few hours training each morning before she makes me come inside to study. And it took a lot to have that. But I want to be strong enough to help. I refuse to be a last survivor again." A look od pride graces her fathers face at her last sentence.
With that the 3 took off. The rest of the group already left before to their training grounds.
Convincing her mother to let her train more than study was the hardest battle Goku had fought, Gohan stayed silent in the background listening, while Piccolo was outside wisely staying away, he was on good terms with the banshee and though he had grudging respect for her being his pupils mother he would do what he could to stay away. It was the loudest her mother had been since before Namek, listening to her parents it was easy to see they both had good points it was mostly that her mother over-powered her father in verbal fighting and made her father so nervous he was unable to get his point across, when her mother started really laying into her father and making him cower Gohan had had enough she wanted to train with her dad.
"Mum, I want to train hard with dad and Piccolo, all the study I have already done would be pointless if we aren't strong enough to defeat the monsters coming and I'm already working on under graduate based science and maths, collage grade English and history and am so adept at engineering I hold my own against Bulma the crowned smartest woman in the world, so a few years of minimal study should be fine. I'll even study after dinner so as not to fall behind. Please. After the androids I'll go back to mostly studying and only training in the mornings. But, I refuse to sit back and watch people die when I can help." Gohan pleaded her case. Her mother had quietly listened.
She was about to answer when Goku good-naturedly patted her on the shoulder, "come on Chi-Chi," resulting in her going through the wall of the house, a tree and smashing head first into a big rock leaving a sizable dent.
"DAD! I had it sorted!" Gohan yelled in surprise.
"Oh my god! Chi-Chi I'm so sorry I guess I've been in space so long I don't know my strength anymore."
Slowly Chi-Chi gained consciousness again Gohan managed to pick her mother up and bring her to a chair grapping the first aid kit and started patching her up while her father stayed in the background remorseful on hitting his wife, he didn't like hitting woman and if he used that power on anyone other than his wife there was a good chance they wouldn't be alive, luckily his wife was strong woman still even though she didn't train like she used to. Slowly her father joined in patching up his wife. Eventually Chi-Chi responded what she was going to say before the accident, "You may train with your father but I don't want you going every day if you plan to train all day long than at least one day a week is for study and another for rest, I want more for you than just being physically strong, a brighter future, is that so much to ask?"
With that all said and done Gohan was able to train intensively with her father and Piccolo.
Training with Piccolo was no picnic he was a tough teacher and Gohan excelled. Training with her father as well as Piccolo was a completely different thing. Her father was as tough as Piccolo when they sparred. Though she was getting adapt at fighting 2 opponents at once. Every evening she was exhausted though she somehow managed to get enough revisions in for her mother's liking. Once again the days started to merge as they got into a familiar pattern all getting stronger and stronger.
After a year Chi-Chi demanded Goku and Piccolo get their driver's licenses as there would be no training that day so Gohan decided to visit Bulma much to her mother's excitement, the sciences was good to study, had lots of potential in its field.
When she got there, she saw Yamcha training in the yard and a spaceship similar to the one her father had used to get to Namek off in the garden, must be for Vegeta, after he had learnt what it took for her father to get as strong as he did and become super Saiyan Vegeta was determined to succeed as well. Something about not being the lesser to a third class warrior and something about being a prince of the Saiyans, Gohan wasn't sure nor understood his reasonings, she was technically a princess and if her Grandfather lived to her 16th birthday she would be crowned first in line above her mother who refused the title and by her 21st birthday her grandfather was adamant about retiring and crowning Gohan Queen to the Ox-Kingdom not that many knew about it nor did the Ox Royal family do much in ruling they were simply a face of the Kingdom keeping hope after her Grandfather's earlier years classed as a tyrant, while an elected government ran the country, like most of the countrys in the world. Though knowing all that and what would be expected of her later in life she still didn't understand Vegeta's way. Maybe when she was older it would be more clear.
Either way she was happy for today to get to do some more practical work with Bulma. Before she made it to the front door however Vegeta paused his training coming out of the spaceship after noticing her energy in proximity.
"You! Brat! Why are you here? Has your father followed? I want to test my strength against him!" Demanded Vegeta.
"Sorry Vegeta, it's just me. I'm here to see Bulma, mum refused to let Dad and Piccolo train me today or let them train as she wants them to get their licences. So, I'm here training my mind as it were."
"Tell me," Vegeta started in a sort of kind tone, well at least for him, "How old are you exactly?"
"Um.. I've just turned 7 last month, why is that? Do Saiyans age differently?"
"Come, we will spar. If you do well against me then I may answer your second question"
Gohan curious to see how soft her teachers had been on her wanted to test her strength against someone who wouldn't pull their punches and followed Vegeta into the ship. Once inside he set the gravity to 50x Earth gravity, Gohan nearly fell to the ground never having experienced such a change in gravity it took her a few minutes to adjust, luckily Vegeta gave her that time. Once she was moving freely, which happened quicker than she would of thought Vegeta struck. Gohan barely managed to block the punch, before she could counter Vegeta was sending kicks almost too fast for her to block or doge, Gohan felt very sloppy in her technique having not been used to the gravity and still trying to find a rhythm. Luckily within 10 minutes they were sparring properly and Gohan seemed to be holding her own. As she predicted Vegeta didn't seem to be pulling his punches, as noticed when he got a few good ones in. She could feel her power growing with each minute they fought, her assumption that Vegeta wouldn't hold back seemed to be correct as each time she tried to push further to get the upper hand Vegeta was able to counter and push her more and more. After around an hour of this Gohan was at her limit breathing heavy while Vegeta was only slightly out of breath, yet he seemed impressed not that he would say it out loud, nor show it in anyway except not throwing insults.
"Not bad for a third-class half breed, you already sit above a lot of second-class full breeds and even a few elites I knew. Guess I should answer your previous question. Saiyans age slower than humans it would seem. Your father and I will keep looking the age we do now, which would be roughly our mid to late 20's in Human terms for quiet a few decades slowly aging onwards by the time your banshee or the woman is over 80 – 90 Human years I will barely look 40. I'm not sure about you, considering you are far more advance than an average 7-year-old but age much the same in looks, we will find out later in life, if I stay on the backwater mud ball of a planet." Having explained more than he planned not realising that he was talking so openly to this little girl in front of him, catching himself, his attitude changed quickly, turning his back to Gohan towards the console, "now begone! I will return to my regular training!" He dismissed abruptly.
"You, being Royalty shouldn't be talking so dismissive to other Royalty especially when you're on their planet." She saw him tense probably not knowing her history or Lineage at all, not that Gohan wanted to use it to her advantage it was just how she was born, before he could respond after turning around to face her. "Thanks for the spar Veggie, I now know dad and Piccolo have been going easy on me." A quick sweet classic Son smile, and she was out of the ship before he could respond, after a quick wave to Yamcha that was watching the ship she set out to look for Bulma her original target.
A few hours later she had been having a break after working on some equations with Bulma for a new capsule design when they heard a huge explosion. Rushing out to the garden they noticed the space ship blown to pieces and no sign of Vegeta, Bulma rushed out to the site while Gohan stood back she could feel Vegeta energy though weak was still alive, buried under all the rubble, what she witnessed next was a sight of tenderness she hadn't even seen her parents show. Once they were sure Vegeta was in one piece and just needed rest she excused herself knowing no more work would be done and decided to check on her Father and Piccolo's exploits for the day. Turns out they had no clue what they were doing and after watching them drive or was it race, she was glad that she never had to get in a car with them any time soon as it turns out they both failed in the end. That night when the trio had made it home Gohan was preparing her earbuds for the onslaught of her mother voice at the fact of her father and Piccolos incompetence. Instead Chi-Chi just fainted. Nothing more was said on the subject for quiet some while.
The next day they started their vigorous training once more and the days rolled into one and other once again, Gohan was unable to visit Capsule Corp again, especially when she made her father and Piccolo go harder on her training.
Over the next 2 years they all got a lot stronger, Gohan especially, she felt like she was working with a barrier on, that she could get stronger but was unable to access it. She told her father and Piccolo such and after some debating they agreed that Gohan was close to the Super Saiyan barrier she just needed the mental push to go over. Sadly, they just didn't have enough time as the androids would supposedly be attacking the next day.
Year 767, May 12th
The day finally came as they were flying to the alleged location, landing on a cliff overlooking the City Gohan, Goku, Piccolo and Krillin, whom they met on the flight there, were greeted by Yamcha, Tien and Bulma, carrying a baby.
Gohan was so shocked by this and when Krillin asked if it was Yamcha's kid and he denied it the non-surprised look on her father face really threw her.
Goku walked right up to Bulma, "I bet he's Vegeta's kid, isn't that right Trunks?" Goku addressed the baby who was hiding his face shyly into Bulma's chest. He said it in his usual cheery voice but Gohan notice a tinge of something else flit across her father face when he said it. Like he knew but didn't really like the fact of it. Not trusting what she saw Gohan put it behind her and focused on the conversations.
Everyone gasped at that while Bulma just looked annoyed. "Now who told you? I wanted it to be a surprise."
Piccolo chose then to speak up wanting to get away from the baby talk, "Speaking of Vegeta, where is he?"
"No Idea, not long after I found out I was pregnant and told him he took off in that darn spaceship, I haven't seen him since. Not that I really mind, I was too busy caring for Trunksie here."
"Don't worry guys, Vegeta will be here, it's not like him to miss a good fight." Goku reassured the group.
With that talking stopped and the group was watching the city below, suddenly Yajarobi arrives with a new batch of sensu beans, though not surprisingly not staying for the fight. As he is about to take off Gohan comes up with a theory she tells the group. "What if we can't sense them, they are machine so probably won't give off an energy signature."
Next thing they know Yajarobi's car is basted out of the sky, when the group search the sky they notice to people in the air, and Gohan's theory was proven correct when they flew into the city and none of the fighters could sense an energy signature. Splitting off to search the city the old-fashioned way while Gohan was sent to rescue Yajarobi. On her was back to Bulma wanting to help her Father and the others not sit on the sidelines, as she was about to leave even with Bulma trying to convince her to stay back she noticed Krillin bringing Yamcha slung over his shoulder severely injured, on closer inspection Gohan noticed a giant hole in his body Bulma started to freak out so Gohan grabbed the bag of sensu's and quickly administered it to the fallen warrior. Once Yamcha was recovered he was determined to get back to the fight as he had information the rest we're sure to need. The three fighters rushed off following the energy signals of their comrades leaving.
Upon landing the first thing Gohan noticed was her father's ragged appearance, he hadn't been fighting the fat clown looking android for that long so there was not way the android could of beaten him so badly. Krillin threw him a sensu bean though it seemed to make him worse.
Voicing the only conclusion Gohan could come up with, "it's the heart Virus! It was supposed to of attacked him over a year ago but never did." She concluded.
Piccolo tried to rush in to save Goku, but the older looking android stopped him lasering him in the chest. Things were looking bad all around when her father dropped out of Super Saiyan and fell to the ground unconscious.
Out of seemingly thin air Vegeta kicking the Clown one away and kicking Goku's body to Piccolo whom was apparently faking the injury waiting for the right time to attack, before Vegeta showed up. "Nobody kills Kakarot but me. Get him the medicine or whatever, he still owes me a re-match. In the meantime, I guess you 2 uglies will do." Addressing the Androids ready to take over attacking.
Yamcha volunteers to take Goku back home to get treatment insisting Gohan stay as next to Vegeta she is now the 2nd strongest. The fight between a now super Saiyan Vegeta and the now named android 19 was relatively quick, in the end only 19's head remained, realising he was way out classed the old man named Android 20 escapes to the nearby cliffs, with the z-fighters following.
After searching for what seems like hours #20 showed himself by trying to suck the life out of Piccolo, luckily Gohan noticed Piccolo's Ki fading and managed to kick him into some cliffs. Before Gohan could continue her assault the purple-haired teenager from the future shows up and in the ensuing confusion when they find out from the future kid that this is not the android who attacked his timeline, #20 blasts Bulma's car out of the sky, whom was trying to follow the fighters, and disappeared.
During all the confusion and arguing about what had just happened, Gohan learns that this teenager is in fact Bulma and Vegeta's son from the future, that the guy they were fighting #20 is Dr. Gero the creator of the androids and that the ones from Trunks' timeline are called androids #17 and #18. Thanks to Bulma's help they find the general location of his lab is rumoured to be and all the Z-fighters besides Gohan leave to search the mountains for Dr. Gero's lab in hopes of getting there before him and stopping them being activated.
Gohan however is tasked with flying Bulma baby Trunks and Yajarobi home before she can go and check on her dad. What a flight that was, it took a lot longer than usual. Finally dropping her passengers off at Capsule Corp. Gohan heads off home. Hoping the rest of the fighters are doing okay as most of the fighters Ki's are back to resting and scattered around. Making it home she sees Yamcha and Trunks loading her father onto a plan along with all his bedding. Just as she is about to address the group her mother comes out of the house and tackles her to the group so happy that she is alright. Turns out the 2 androids from trunk's time have been activated as well as another one and are stronger than the ones he fought and also on their way to his house, hence the moving her father to Master Roshi's. On the way Bulma called wanting to talk to Trunks sending through a photo of what looks like his time machine, though old and worn down sitting outside Ginger town. At the prospect of an adventure Gohan volunteers to go with trunks to check it out.
TBC..
