I don't own Dragon Ball Z or any of the characters.
Gohan, Trunks, Goten, Tien and Krillin flew as fast as they could to the Son house. They all remained silent as they flew. Suddenly Goten flew to his brother and got his attention.
"Do you think mom's going to like me Gohan?" nervously asked Goten.
Gohan smiled and laughed. He knew this would be the first time Goten had seen their mother since he was three and he was just as excited about seeing her as he had been meeting his dad.
"Mom's going to love you Goten. There's nothing for you to worry about. I'm just a bit worried about what she'll think of me. Here she wanted me to become a scholar and now I'm a battle hardened warrior that's missing an arm. I wouldn't be too surprised if I get yelled at and a frying pan to the head for not becoming a scholar and becoming a warrior instead." responded Gohan.
Goten could remember hearing from both his brother and the Bulma from his time that his mother, ChiChi, had forced Gohan to study and wanted him to become a scholar. It was impossible for Goten to imagine Gohan as anything other than a warrior. And Gohan had realised that same fact a long time ago to.
After he had lost his mother Gohan had focused on nothing but training and even though he hated what the Androids had done, fighting against them had made Gohan realised what he really wanted to be since he first started training. He had Saiyan blood in his vein and Saiyans were warriors, not scholars like his mother wanted him to be. The dream of him becoming a scholar was ChiChi's not his. Gohan only wished he could get his mother to understand that and perhaps convince her that it was the right path for his younger self to.
Trunks flew towards his two friends to see what all the commotion was about. The lavender haired warrior looked at the two Son brothers with a confused look on his face.
"What are you two talking about?" wondered Trunks.
Goten looked back at Trunks.
"I was just asking Gohan about my mom." replied Goten.
Trunks was speechless. He lowered his head and felt a little self disappointment. This was a personal matter between brothers, he shouldn't have gotten involved. Trunks had met ChiChi a few times, but that was only until he was four then she and her father, the Ox King, had been killed by the Androids.
Krillin ad Tien noticed that the three future Saiyans had started to slow down. So the two Z fighters went to investigate and find out what was holding up the flight to the Son house. Krillin was the first to speak.
"What seems to be slowing you three down?" asked Krillin.
Gohan looked at his friends then to his brothers and back to his friends. Trunks and Goten were both being quiet and looked like they didn't want to talk. Gohan knew he had to speak for his two younger brothers.
"Goten just asked me about what mom was like." said Gohan.
That's when Krillin made a connection. He had never once heard any of the future Saiyans mention anything about ChiChi. Perhaps it wouldn't hurt if he asked what had happened to the wife of his best friend?
"So how is ChiChi doing? From what you told us about your world ChiChi has to have changed a lot to let you and Goten fight. How has she been in your world?" unknowingly asked Krillin.
Gohan sighed and looked away from his friend. Trunks and Goten became lock lipped and looked like somebody had died. Finally Gohan answered his friend's question.
"Mom's dead in my time. She died when I was thirteen, here years after the Androids showed up. She was visiting grandpa at his kingdom when the Androids attacked and destroyed everything. After that I trained harder than ever sworn to defeat the Androids. They had taken everything from me. All I have left it Goten, Trunks and Bulma." sadly answered Gohan.
Krillin and Tien were both shocked and apologies for bringing up any painful memories. Gohan assured then that he and his brothers would be alright. The rest of the flight to the Son house was done in complete silence.
The only time anyone spoke was when Krillin told Tien to go get Chiaotzu and that they were going to move Goku to Master Roshi's house. Tien understood and left to go get Chiaotzu. The three half-Saiyans and Krillin picked up on their speed knowing the Androids or the heart virus could claim Goku's life at any minute.
They had finally made it to the Son house. The four landed. Krillin knocked on the door and a few seconds later ChiChi answered it. Gohan smiled at his mother. Trunks and Goten were both shocked by seeing Son ChiChi again after her being dead fourteen years in their time. ChiChi had her black hair in a bun, brown eyes, wore a long sleeved pink shirt, pink pants, a purple sleeveless Chinese dress, and red boots.
Suddenly Yamcha rushed to the front door. The former bandit looked at his friend and the three time travelers. Yamcha smiled as he adjusted his tattered orange go to keep the sleeve from falling off his shoulder.
"I'm glad you made it here safe Krillin." said Yamcha.
"What about Goku?" asked Krillin.
"Don't worry he's safe. He's sleeping right now. I see you three are back. Then if you're here you must have defeated the Androids." assumed Yamcha.
The four warriors all looked guilty. Krillin quickly explained what was going on and that they had to move Goku.
"The Androids we fought turned out to be fakes. Now the real Androids are out trying to find Goku. We need to move him to Master Roshi's before they find him here." exclaimed Krillin.
Yamcha and ChiChi couldn't believe it. The Androids were on their way to fight Goku. They just couldn't believe it. ChiChi couldn't believe it more than anyone and started to go into her overprotective wife/parent mode.
"You expect me to let you move my husband when he is still unconscious. We live in the middle of nowhere. The Androids will never find us. I'm not going to let Goku leave this house until he's able to walk out of this house by himself. Do you hear me! Goku is not leaving!" yelled ChiChi.
Krillin, Trunks, and Goten were all quivering before ChiChi. Gohan was the only one who remained calm. The one armed warrior approached his mother. ChiChi looked at the man approaching her and noticed he looked somewhat familiar.
"The only way you are going to believe us is if I tell you the entire story. We don't have much time so I'll skip most of the details. My friends and I came back in time using a time machine made by Bulma Briefs. The boy wearing the Capsule Corp. jacket is Trunks, the son of Bulma and Vegeta. The other teenager is my brother Goten. All three of us are half-Saiyans. Trunks got his Saiyan blood from Vegeta and Goten and I got our Saiyan blood from Goku. I'm Gohan." explained Gohan.
Yamcha was utterly speechless. ChiChi looked about ready to faint. Something told Gohan that his mother still didn't believe him one hundred present so he did the only thing that would make her believe him, he told the truth.
"I know this is hard to believe but I'm telling the truth. If I wasn't then how would I know you are about seven months pregnant with your second child?" assured Gohan.
ChiChi nearly lost her footing but caught herself before she landed on the ground. No one had noticed that ChiChi's stomach had grown just a bit over the past seven months. She just wasn't the type to show a pregnancy that very easily. The woman was still in disbelief.
"How do you know I'm pregnant? I haven't told anyone yet, not even Goku." shockingly said ChiChi.
Gohan smiled at his mother.
"I know because I'm telling the truth. I am Gohan. You'll just have to decide if you believe me or not mom." stated Gohan.
Tears formed in ChiChi's eyes and she began to cry. She embraced Gohan and held him tightly in her arms. Gohan returned his mother's hug trying his best not to cry. A warm smile was on ChiChi's face.
"You are my little Gohan. But what happened to you? How did you lose your arm and get that scar?" worriedly asked ChiChi.
Gohan sighed before answering his mother.
"I've been fighting against the Androids for nearly twenty years. At first you wouldn't let me fight you kept on insisting that I had to become a scholar. But I couldn't just let innocent people die. I fought against the Androids for a year before you finally gave me permission to fight them and held back on my studying, just until the Androids were defeated. All was going fine until three months after my thirteenth birthday. The Androids had beaten me up pretty bad and I was on life support at Capsule Corp. You left Goten, who was only three at the time, at Capsule Corp so you could go visit grandpa and tell him how I was doing. The Androids attacked the Ox kingdom and you and grandpa died. I didn't find out until Bulma told me a week after the Ox kingdom was destroyed, the same day I was taken off of life support. I left Goten at capsule Corp. and began to fight the Androids on my own more than ever. When Goten was ten I took him with me so he could learn to survive, but I always dropped him off at Capsule Corp. and made him stay there when I was fighting the Androids. Then four years ago in my time I took Trunks and Goten on as my students. It was in a fight with the Androids at Super World that I lost my arm and got this scar. A few weeks later I was nearly killed by the Androids. Trunks and Goten were able to find me before I was dead, though I was as close to death as one can get without dyeing. Bulma harassed me about being more careful and ever since them Goten and I have been living at Capsule Corp. with Bulma and Trunks." explained Gohan.
ChiChi dried her tears and looked at the other two young half-Saiyans. She guessed that the lavender haired teen was Trunks. The other teenager looked like a copy of her husband with only slightly longer hair and was much younger. That teen had to be Goten, the child he had not yet given birth to.
Goten noticed as his mother approached him. A warm smile was on the woman's face. Goten was nervous and shaking like a leaf when his mother was close enough for him to breathe on. It was just too much for the young Saiyan to handle.
"So you are Goten? It's very nice to meet you. You do look a lot like my husband, even more than Gohan does. Does Goku know about you and who Gohan is?" noticed ChiChi.
Goten nervously shook his head.
"Dad does know about Gohan and Trunks, he practically fainted when he found out who Trunks' parents were. But he doesn't know about me. Although I did almost let it slip a few times. And I'm surprised he didn't find out sooner by how I look. Everyone always says that I look exactly like dad, but I'm glad I looked different enough for him to not notice me. I hope he and you mom are both willing to accept me." answered Goten.
ChiChi embraced her son. Goten returned his mother's embrace, tears flowing from his eyes.
"From what I have heard you both had hard lives. I know your father will be proud of you when he finds out who you are. I now I am proud of you Goten. And I'm proud of you to Gohan." stated ChiChi.
Everyone seemed to be enveloped between this touching moment between parent and child, all but one. It seemed that Trunks was the only one who hadn't forgotten that the Androids were closing in and could be near the Son house at any minute.
"I hate to be the bearer of bad news, but we still have the Androids to worry about. They could be here any second. We have to move Goku before they show up." reminded Trunks.
Everyone looked at trunks. Gohan looked back at his mom.
"Trunks is right mom. The Androids are brutal killers. They won't care that dad can't fight back. The only way to keep him safe is to get him to Master Roshi's house and fast." said Gohan.
ChiChi nodded and looked at the older version of her first born.
"Alright you can take Goku. Just make sure nothing happens to him. And I'll be having a little talk with you mister. You don't think you're going to get away with becoming a warrior and not, a, scholar do you? I could just give you a lecture right now, but I'll save it for later. Right now you have to get Goku to safety and defeat those Androids." stated Chichi.
Trunks reached into the capsule container they had brought to the past and selected a capsule. He let the capsule go and a jetcopter appeared before the group. Yamcha and Krillin collected Goku and began to bring him onto the jetcopter. Trunks and ChiChi grabbed some supplies and put it on the jetcopter.
"I think Goku's packed on a few pounds." sighed Yamcha.
"Give him a brake. He hasn't been himself lately." replied Krillin.
Krillin and Yamcha laid Goku down on a mattress. Trunks put a blanket over the father of his master and best friend. The three warriors looked at Goku.
"Yamcha where is Gohan? The kid not the adult?" asked Krillin.
"I don't know Krillin. But he should be here any time now." answered Yamcha.
The three were able to hear ChiChi from outside and she sounded pretty happy.
"Gohan back!" cheered ChiChi.
The three raced outside. Sure enough a young Gohan was coming into view. The younger Gohan landed on the ground. ChiChi raced to her son and squeezed him in her embrace.
"My baby, you're home. I'm so happy to see you." happily said ChiChi.
The young Gohan looked at his friends and the three future half-Saiyans.
"What are you guys doing?" asked young Gohan.
Gohan answered the question for his younger counterpart.
"The Androids could be here any minute. We have to move dad before they get here. We're taking him to Master Roshi's house." told Gohan.
Everyone border the jetcopter. The jetcopter took off and sped to Master Roshi's house. Hopefully they would get there in time before the Androids found out what they had done.
I looked it up and Senzu beans can't heal any old injuries that have already healed. Take Yamaha's scars for example. He's had Senzu beans and he still has scars. That's why Gohan still only has one arm and I like the disabled badass trope. Comment if you like the story.
