Everyone is happy and cheering to finally see goku after some years (except Vegeta obviously) all the while goku has a confused face before tell why he has one

Goku: wait your all alive? But how both freiza and cooler was coming here with their dad? I thought someone was going to die.

Y/n: well I took on cooler and by the time I was done the stranger over there *points at stranger * kill everyone else.

Goku: well it nice to meet you um...

???: well if you don't can I talk to you and your brother in private?

Goku: alright.

Gohan: but you just got here after a few years your just going to talk to some stranger.

Goku: I will be quick gohan. Right?

???: I just need to ask you a few things that all.

Y/n: let see what we have to say then we can all do something.

Gohan: fine.

???: well then follow me you two.

The three of them fly to a empty spot near by

???: well then you must be goku *points at goku* and you must be y/n *points at y/n*

Y/n: yes that is our name but who are you?

Trunks: I guess it time to finally tell it so my name is trunks.

Goku: so you beat freiza by yourself.

Trunks: that I did but one question for you goku. How did he said alive from namik?

Goku: well you see I kinda let him live. That probably was a bad idea.

Trunks: if I hadn't come everyone here would have died.

Y/n: *hits goku head* how could you try to let that monster live!

Goku: jeez that hurt sorry ok.

Trunks: also y/n how did cooler survived?

Y/n: well he told me a part of him was still alive and somehow his scientist somehow build him a body.

Trunks: well then on to my next questions. You guys are able to go super sayain right?

Goku and y/n: of course.

Trunks: you two wouldn't mind showing me?

Y/n: why not.

Both goku and y/n turns Super Saiyan infront of trunks

Trunks: that a super sayain alright now let me show you mind.

Y/n: wait what?

Trunks then turn super sayain himself leaving y/n and goku speechless meanwhile Krillin was saying something until Vegeta yelled at him

Goku: so you can turn super sayain that amaz-

Goku was cut off by trunks attacking goku with his sword only for gokubto block them all

Y/n: ok? What was that for?

As y/n finished trunks quickly attach him with kick and slashes only for y/n to dogged them and pin trunks to the ground

Trunks: ok you can let go now.

Y/n lets trunks get up and he turns off super sayain

Trunks: so what my mom said was true you both are really impressive people.
