Ten Years Ago
The mountains on the outskirts of Kumogakure were some of the best places for meditation. An older man sat down on the cliff with his eyes closed, simply becoming one with nature; breathing calmly, and getting rid of the troubles on his mind.
For the moment, it felt like no one could throw off his focus. The thought of that brought a smile to his old, wrinkled face. He had long, white hair that was currently flowing in the wind. The man's face was concealed by a fox mask, and his attire consisted of an all black long sleeve, and matching pants. He wore the usual Kumogakure jounin flak-jacket over his outfit, with his head band tied around his right arm.
He continued his deep meditation, letting his energy flow freely. As a result, electricity crackled all around his body. He let out one last breath and let his energy fall, and pushed himself off of the ground.
Behind him, there was a small hut, which he identified with as a home. He was walking to go inside, but as he was about to slide open the door; he heard a loud crash. He turned around, seeing that not too far from his house; there was a giant plume of smoke that could probably be seen from the village. It was followed by the appearance of a large chakra signature he couldn't identify.
As a shinobi of Kumogakure, it was his job to go and investigate. He went to the edge of the cliff and placed his hands on his hip, and quietly sighed. The man felt other shinobi already moving quickly toward the scene, but he was lucky enough to be the closest to the crash site.
In a flash of electricity, he disappeared, and could be seen jumping from mountain to mountain to close the distance. He didn't know what he would possibly be coming across, but he mentally prepared himself before he dropped down to the site of the loud crash.
When he arrived, he saw two rogue ninja already there. He groaned, "You two, get out of here. This is Kumogakure business." He looked past them to see a large metal pod, steaming as it sat in the debris of a crushed boulder.
One of the ninja laughed, "That's hilarious!"
The other quickly ran through hand seals before taking in a deep breath and shooting out a large blast of fire, that expanded and turned into a wall when it connected with the man.
The two shinobi turned and laughed to each other, "Wow, I can't believe it was that easy!" They yelled in unison.
Their celebration was cut short by a kunai knife landing in between them, with an explosive tag tied to the end of it. They both shot each other a look, "Damn," one of them mumbled. They knew they would have to leave the site for a moment, both of them splitting in the opposite direction.
When the tag burned all the way, there was a simple poof of smoke; as it turned out to be the man from before. There wasn't a scratch on him, he formed two clones quickly and they left to pursue the rogue ninja.
He now turned his attention to the metal pod. The man was more than confused as to what was going on. It was silver, with a small red-ish window in the front of it. He walked up to it and tapped it with his foot gently, and surprisingly it opened.
His eyes widened behind his mask and he gasped once he saw what was on the inside. He took a step closer to get a better look.
It was a baby! It was no normal baby, but a baby nonetheless. It cried and held its arms out for help like any other child, and the man had no choice but to help the baby out of the pod.
It was a boy, and the man found that out the hard way because he peed directly on his mask. The baby started laughing and the man couldn't even be mad. He ran a hand through the boy's spiky black hair and almost smiled, "Hey there kid," he greeted the child.
His eyes widened once he realized that the massive chakra belonged to the child, "Wow, you're strong."
Through all this he didn't notice that a tail wrapped around his arm while he held the child, "You're a weird one too aren't you," He laughed a bit to himself, before tickling the kid on his stomach and looking past everything weird about him, understanding he was still a baby. "My name is Gohan! What's yours?"
He knew he wouldn't be getting any real response, just a confused stare. Gohan still smiled, "I'll call you … Goku," He said as he looked at the boy's tail, "It seems fitting anyway."
A few moments later a squadron of Kumo shinobi landed at the scene, surrounding Gohan in an instant.
"Don't worry, I have everything under control," Gohan said as he turned to the crowd, still nurturing the baby. "There are rogues roaming all around here though. Not to take control of this situation, but I say you guys take this pod and hand it over to the ANBU, and report this to Lord Fourth."
One of the men stepped forward, he was tall and slim. He wore his headband over his eye, and his head was wrapped up in bandages. The man offered a light smile, "We understand completely, we'll trust you to relay this to the Raikage while we clean up the scene." His tone did however get serious, "You're being watched, so don't try anything with that kid, okay?"
"Yes sir," the man bowed respectfully before disappearing in a crackle of electricity.
The other man turned to address his squad, "Ok, lock down the area and secure the pod. We've got a lot of work to do boys."
. . .
(The Raikage's Mansion)
Gohan was slowly walking down the halls of the building while cradling the baby. As he strolled, a whole desk was thrown through the wall of the building; making him pause and cover the eyes of Goku.
"WHAT THE HELL DO YOU MEAN AN ALIEN!?" The Raikage yelled while looking for other things to throw in his office. Apparently he had just heard the news.
The masked man playfully covered Goku's ears, "This should be fun." He took another cautious step forward, right through the newly created hole and stood before the Fourth Raikage, "Yes, an alien, sir. His name is Goku actually."
"YOU NAMED IT?" The man screamed before slamming his fist against the wall, "WE NEED TO EXTERMINATE THAT THING IMMEDIATELY."
The Raikage's assistant wasted no time walking up to Gohan and removing Goku from his grasp. She cradled him close to her chest with a motherly touch that Gohan could never provide, "Raikage-sama, don't be irrational." The woman smiled at the baby and tickled its nose, getting Goku to laugh.
"This isn't your place to speak right now, Mabui!" A pointed at her with a shaking finger, "Keeping this child can only lead to nothing but trouble."
Gohan interjected quickly, trying to defend Goku, "Actually, sir, I see that our new friend can end up being a powerful asset to the village in the near future." The man's statement only got a grunt out of the Raikage, but he calmed down and seemed to be more interested. "Surely you noticed the abnormal amount of chakra this baby has."
The Raikage nodded his head, "I did, but we have enough targets as it is!" He instantly started shaking his head in disagreement, "With two Jinchuriki already in the village, adding another super weapon to the mix would only make us a bigger target to the other major villages, and it makes us seem suspect!"
The masked man sighed, "I still understand, but that's why we don't dress up this situation as chance to turn him into a military super weapon, but just a regular shinobi. Nobody has to know that we're harboring an extraterrestrial with otherworldly strength. We'll bring Goku along like any other shinobi and let him realize his potential along the way," Gohan walked over to Mabui and she handed Goku back to him, "There really aren't any cons to this situation, as long as we keep it as low key as possible."
A was now pacing back and forth, gritting his teeth through it all. He stopped in the middle of the room and shot a glare toward Gohan, "And what if he doesn't realize his potential?" Before Gohan could interrupt, A held his finger up to make him wait. "Or even worse, what if he gets too strong to the point where we can't control him, and becomes an international problem. Maybe even a catalyst of war? There's endless possibilities!"
Mabui decided to add to the conversation, despite being told not to, "Sir, you should consider that we took chances with Yugito-chan and Lord Bee, and they came out completely fine under the same conditions." She had a slight smile on her face when she saw the man's expression change, "Also the extra military power wouldn't hurt, especially if it was kept under wraps. Bee-sama and Yugito can be separated from their source of power, while Goku was born this way. That's extremely valuable."
A furrowed his brow and looked between the three people present, "Look," his tone was deathly serious, and it made a chill run down Mabui's spine. "I want this situation completely handled by the morning, and should anything go wrong; you fuckers better be running as fast you can, because I will make sure you're wiped off the face of the earth the minute it does."
The baby started crying once the room fell silent, and that moment helped Gohan grasp the seriousness of what was going on. He tried to calm the boy down but failed tremendously, "I understand." The man turned around and made his way out the door, and Mabui followed him out.
"Look, Gohan-san, I can take care of Goku on a day-to-day basis, as long as you look over his development as a shinobi," Mabui offered, smiling at Gohan who turned to look at her with Goku still in his arms, "I'm busy as Lord Raikage's assistant, but I can find balance."
"... Don't stress yourself out. I appreciate the offer, and I'll even take you up on it, but I don't want you to stress yourself." Gohan ended with a simple nod before continuing to walk away.
Mabui was confused, but she trusted Gohan for the moment. He was a wise old man and he seemed to have a lot planned for the future. When he was ready to hand Goku over to her, he would, and for the mean time she would stay patient.
. . .
(Mabui's House / 4 Years Later)
Goku sprinted full speed through the living room, being chased by Mabui throughout the house. He did a cart-wheel over her table, and landed perfectly on his feet on the other side. The woman wasn't as lucky, crashing into the table trying to dive for the boy. He could only grin and placed his hands behind his head.
Mabui looked up from the floor and shot a menacing glare at Goku, "When I get up I'm going to give you hell, Goku." She pushed herself off of the floor and kicked the table out of the way. The woman pounded her fist into her open palm, "You NEED to take a shower before you go see Grandpa Gohan."
The boy shook his head and tried to back away, but in one swift movement; he was smacked on his head and onto the floor. She put her foot on Goku's back, "Now get your ass in the shower."
Goku still only laughed, "Okay, okay! I'll get in the shower Mabui-chan!" Once she removed her foot, he jumped up and dusted himself off. He had on a white t-shirt and black pants made specially for him, since his tail could wag happily. The only reason he liked to mess with Mabui is because she always gave him a good reaction.
Since Goku started developing his own personality, hers slowly started changing with him, and her patience had gotten very thin. She picked up new motherly traits that no normal twenty-three year old would have. The woman let out a sigh of relief once he agreed to take his shower, "Please hurry up, Gohan is a busy man." She placed her hands on her hips and waited for Goku to leave the room.
He didn't shower for long, but at least when he came back he was somewhat clean. Mabui picked him up and squinted her eyes, examining him up and down. The woman sat him back on the ground, "You passed, let's go." She offered Goku a smile and her hand. He grabbed it quickly and the two walked out the house together.
Since Gohan is normally stationed far outside the village, they agreed on a meeting point within it to make it easier for her. They had gotten access to a small dojo space that they could quietly bring Goku up to speed with. Their main goal was to train him like a clan noble would with their child, and make him the best shinobi he could be.
When they arrived, Mabui was surprised to see the Raikage himself sitting in a chair, with Gohan standing on his side. Goku let go of her hand and ran to give Gohan a high five, and when he attempted to do the same with the Raikage; he got no response. The man simply stared at Goku.
The masked man looked at the Raikage silently, and then back at Goku, "We're doing something different today, kid. I want you to show Raikage-sama what I've been teaching you." He crouched down and pat the boy on the head, "Can you do that for me?"
"You know it!" The boy yelled cheerfully, before bowing toward the Raikage. "I'm ready whenever you are!"
The man got up out of his seat and grinned. He punched his fist into his open palm, "Really?" He folded his arms over each other and took a step forward. A towered over Goku but the boy didn't falter, and he couldn't help but like that. "You can make the first move.-"
The Raikage barely got to finish his sentence, because Goku was more than ready. He quickly tried to punch the man in his knee, but he jumped into the air. Goku rolled across the ground and jumped back up. He got into a proper fighting stance, but instantly leapt off of his right foot and tried to punch the man again.
Instead of dodging, he held his palm out and stopped the boy's attack completely. He closed it into a fist and lifted the boy off of the ground and tried to slam him into the ground. Goku jerked his hand forward and then pulled back hard. He managed to free himself from the man's grab and flipped in the air, so he could land cleanly behind the man. A wasted no time turning to face the boy.
"Even if I am going easy on you, you're better than I thought," A admitted, "Gohan, you're doing a good job with the boy, but he's still not the sharpest kunai."
The boy furrowed his brow, "Huh, what do you mean, old man!?" He ran forward and jumped off the ground and tried to directly punch him in the chest, but the Raikage swatted him out the air like a fly, and sent him tumbling across the ground.
Goku gained his composure fast, jumping back up. He sprinted forward and acted like he was trying to throw another punch, and smiled once he saw A prepare himself. The man was ready to counter, cocking his arm back, but Goku slid right under him and jumped up just to kick him in the back. He only stumbled forward a bit, but it caught him by surprise.
The man turned to face Goku again and actually went on the offensive. He charged forward and got ready to punch Goku, so he could send him flying, but the boy thought he had an advantage with his quickness. The child tried to slide under the Raikage's body again, but the man changed his approach this time, and grabbed him by the tail.
'Shit,' Gohan watched from the sideline. He knew Goku's weakness lied in his tail, and he was hoping that didn't happen today.
The Raikage wasted no time with slamming the boy against the ground repeatedly. He noticed there was way less resistance this time, and with each slam there was a loud scream of pain. The man was weirdly amused by it, but it wasn't in his plans to kill the boy; rather teach him a lesson. He decided to ease up on the boy, fully extending his arm back, and then throwing Goku straight into a wall.
He laughed like a crazy villain, "That's for calling me an old man you fucking baby!" The Raikage walked up to a surprisingly resilient Goku who was starting to get himself together again. "You're a strong brat, I'll give you that, but you still have a lot to learn. I can tell you're going to be great at Taijutsu, but you need to learn how fully use chakra and ninjutsu or you won't be shit."
Goku grinned and wiped a small smudge of dirt off of his face, "Teach me something then old man!"
"Maybe when you're ready, kid."

I'm not really into long ass prologues, I just wanted you to get to know my Goku a little better. I'm going to jump straight into the main plot from here, hopefully you stick along for the rest of his journey.
