*3rd Pov*
3 years had passed. Many things happen in three years, Ryuu, Goku, and Gohan are currently flying to the Kame house for a reunion. Ryuu is currently 3 years old while Gohan is 4 years old.
'Looks like my uncle will be coming today, I hope I can get him to join us for the Saiyan race to populate and be back in peak, making the universe seven get stronger than before' Ryuu thought and recall the past three years living in the Son family.
*Flashback*
1st year - Ryuu is watching his father, Goku, Training martial arts while Gohan is talking to Ryuu.
"Ryuu, let's go play tag," Gohan said excitedly nagging Ryuu to play.
"Nah, let's watch Father first. I need to ask him a question if he can train me" Ryuu said, Ryuu face is similar to Goku but his hair is from the super Saiyan Goku but black.
"Awww, I just want some bonding with my brother," Gohan said.
Ryuu just continues watching Goku train, not minding Gohan who is currently drawing a circle at the corner of the tree. They are under the tree to hide from the sun and watch Goku since Chichi is cooking food for them.
Minutes later, They got called by Chi chi that lunch is ready. Ryuu and Gohan look at each other and smirk.
"Who goes inside first, eat the best part of the meat," Ryuu said and ran off while Gohan chased him.
"Wah, you're cheating, you are running first, wait for me Ryuu," Said Gohan while chasing inside.
Goku who finishes his training look at his two sons running towards the house for lunch.
"Hehe, they are good at each other, *sigh*, I wish I had a brother to train too," Goku said and walk to the house with his gi still hanging.
Inside the house are Gohan and Ryuu eating meat left and right, while chichi is serving the food one by one in precision with no-spill of the foods like soups, a mountain of Meats.
"Hehe, you lose Gohan, I win the race," Ryuu said while chomping the meat, him eating meat at 1 year old is already weird but who cares, it's anime logic or fanfic logic.
"Because you run first you cheater, next time I will win, Ryuu," Gohan said chomping some meat, meat bun, drinking the soup, and eating rice.
"Slow down eating or you might choke your food," Chichi said and look at Goku who arrive.
" You are sweating Goku, go wipe your sweat first and then eat," Chichi said while throwing a towel.
"Hai" Goku then catch the towel that is thrown at him wipe the sweats, seat down and eat the food.
" Dad, can you please teach me martial arts?" Ryuu asks while eating some meat buns.
Goku looks at Ryuu then at Chichi.
"Ask your mother first, then I will allow you to train if your mother allows it," Goku said and continue eating.
"Can I too, Dad. Since Ryuu ask to learn martial arts, I could also do it right, since I'm the big brother, I should also train" Gohan said eagerly while his Saiyan blood getting excited.
"You can if your mother accept your request" Goku said to them.
Ryuu and Gohan look at their mother who is sitting at the chair who is listening at their conversation.
"No, but if you promise me to learn academic knowledge(don't know how to put it), I will allow it" Chi chi demanded, eating gracefully.
"I will do it if that's the price to learn martial arts" Ryuu said.
"I will too" Gohan added.
"Good, be prepared for what's coming for you, you better not run from your studies, okay" Chichi said.
The two nodded and look at Goku who is eating left and right be it dumplings, tempura, meats or soup.
"Looks like you're mother allowed it, Hahaha, be prepared for your training tomorrow" Goku said.
And just like that, they train for two years while also learning some easy knowledge like 1 + 1, 2 + 2, etc., letters like a,b,c etc.
2 year - There is two kids fighting an adult, the little kid who's two years old round house kick the adult to the left side, while the other kid who is three years old punch the right side of the body, while the adult block the kick with his left hand and grab the punch at his right and throw him off while kicking the 2 year old lightly to the 3 year old kid, crashing him.
"Ugh, it hurts" the two year old said while getting up and helping the other kid go up.
"Let's stop or you're mom will get angry at you two for missing your study" The adult says.
Yes this is Goku, Ryuu and Gohan which you already know but if you don't, I don't know if I should laugh at you or concern for your health at your brain, anyway they return to the house.
"Ryuu, Gohan, tomorrow we will start in our next training, it's how to control your ki and sense ki, Ryuu you have a high ki going wild so we better train at suppressing that" Goku said to them.
"Yes Dad" Ryuu said.
"Dad, what's the use of training ki" Gohan ask.
"Hmm, I don't know, but it can help us suppress our ki and be undetected by the other martial artist who train ki, and it can do cool stuff too, like kamehameha, that shoots out a blast full of ki." Goku answered Gohan who question what's the use of ki.
"Wow, can you show us that kamehameha tomorrow, we want to learn it too" Gohan said excitedly.
"Yeah, show us the kamehameha dad" Ryuu said.
"I will, now let's go or we will be screwed by your mother this time" Goku said and run off to the house, while Ryuu and Gohan follow him.
Seconds later, they arrive at the house and get inside, to see chichi waiting for the kids.
"Good, you three finally arrive. Ryuu, Gohan let's study for math today" Chichi said and they follow not questioning.
"Bye bye kids, study hard okay, don't make your mother get angry" Goku said.
With that the flashback is finish, for the next three years is them learning ki.
*Flashback ends*
While Goku, Ryuu, and Gohan is flying towards Roshi's house, a space pod entered the earth crashing towards a farmland.
The space pod open, and a man with tail got out, looking at his surrounding he turn on the scouter to see who have a strongest power level.
"This planet should be where my brother land, according to mother" The man with a tail said, while his scouter beeping until it reads towards the direction where piccolo is meditating.
"That should be kakarot's Power level, what a weakling" The man with tail said with contempt and fly off towards the power level.
(don't know the power level of piccolo when they fight raditz)
While Goku is oblivious of the man who arrive in the planet, just flew off towards the kami house.
