(I think I got it right also this chapter is only on Y/N)
As it becomes morning someone barges in
Goku: Morning Y/N it's time to get up
Y/N: No thank you
Goku: Come on we don't have time to waste your brother already got up and is training with vegeta today me and you are going in the hyperbolic time chamber
Y/N: Do you mind explaining what that is?
Goku: ohh yeah you don't know about it it's a chamber where a day out here is a year in there
Y/N: hmm that sounds cool but does it affect my age?
Goku: yes it does sadly
Y/N: Well can I get something to eat first
Goku: yeah sure
(Time skip to time chamber)
Y/N: so where is this chamber thingy?
Goku: it's on the lookout
Y/N: mind explaining what that is too
Goku: just a floating castle no biggie
Y/N: ooo sounds like home
Goku: like home?
Y/N: yeah me and my brother basically lived in a floating castle off is space I don't know where in space
Goku: hmm interesting well I'll use instant transmission to get there hold on to me
Y/N: instant what?!?
As Y/N finished his sentence they teleported to the lookout Y/N with a shocked expression
Y/N: What was that and where are we?!?!?!!
Goku: Don't be alarmed it's a technique I learned to transport me anywhere as longest I feel the energy of where I wanna go and this is the lookout
Y/N: ok but where do we train and where is the food
Goku: oh that's in the chamber so we need to get to work
Y/N: yes sir
The two walked into the lookout to greet Mr popo and left to the chamber
Goku: Alright little buddy this is the time chamber
Y/N: you mean a void of nothing but white wow very depressing
Goku: yeah i guess you can put it like that so you are my training partner and it's great because you can go super saiyan too speaking of which training starts now
Y/N: aww ok I didn't get to eat yet
Goku: no time for eating when the world might end
Y/N: goku are you feeling ok?
Goku: yeah why
Y/N: cuz I never heard you say no time for food the last couple days I've lived with you guys
Goku: sorry it's been a while since I had a decent training partner that doesn't want to kill me
Y/N: wait vegeta wants to kill you? But why
Goku: I don't know we're more like rivals than enemy's any ways time to start
(Goku goes super saiyan)
Y/N: Alright guess I'll go super saiyan too
( Y/N goes super saiyan)
Y/N: so what now
Goku: we fight to get stronger
Y/N: is that all you guys do?
Goku: yup pretty much no more questions begin
With no time to react goku appears in front of Y/N and kicks him in the stomach flying back Y/N gets up and flies towards goku and fires up a final flash goku powers up a kamehameha and both fire, gokus has kamehameha was on the verge of hitting Y/N but Y/N reappears behind goku hitting him on top of the head sending goku down goku gets back up as if nothing happened with a shocking reaction
Y/N tries to land a KI blast but goku is too fast Y/N powers another final flash as goku approaches him Y/N fires and lands a hit
Goku: not bad but you need more training if you want to be beat me
Y/N: wow you are super strong now
Goku: yup me and my son gohan used the chamber a couple of days ago now time to train you to become stronger than cell
Y/N: I still don't know this cell guy but why do you have so much faith in me
Goku: cuz I see great potential in you and your brother
Y/N: wow thanks for the words of inspiration.
