(Y/n's Inner World)

Y/n:*groans* what the?

Kirito: s...son...

Y/n: father?! What happened?!

Kirito: Miller....he killed all of our friends...

Y/n: what!?

Miller: there you are you brat you and me are going to hell!!

He stabs Kirito causing him to scream in pain. Y/n tries to cover his ears but he couldn't block the screams.

Y/n: stop it!! Please!!!

Miller: what's wrong to weak to save them like in 27th Floor?

Y/n: no more!!

Miller: too bad because I raped your girls and killed. Their screams were music to my ears.

Y/n: YOU BASTARD!!

He punches Miller's face sending him to a wall and charges his power.

Y/n: KAMEHAMEHA!!!

The wave hits Miller destroying every cell in him. Y/n powers down and rushes to his dying father.

Y/n: father please don't leave me!!

Kirito: I'm sorry I wish I can be with you longer to see our little angels and demons grown up...Goodbye my son.

Then he dies turning into pixels.

Y/n:.....

Y/n: if only I was stronger....if I founded the chaos emeralds....if I had a power to make me stronger to save them all....

He charges up his energy as he screams.

Y/n: IF ONLY I WAS STRONGER TO EVEN PROTECT THEM!! HAAAAAAAAA!!! HAAAAAAAAAAAAAAAAAAAAAAAA!!!

Y/n: i have Goku and Vegeta's Ki/God Ki?!

????: come on let's spar my descendant!!

????: Come on do you have the saiyan's pride!?

Y/n: huh!?

Y/n: Son Goku and Vegeta!?

Goku: hey Y/n!!

Y/n: wait how did you know me!?

Vegeta: we've been watching you since your creation. You are in deep trouble because two people will rule Earth if you don't become stronger!!

Y/n: who are those two!?

Goku: I don't know but remember what your spirits told you.

Y/n: those....I see but I need their names.

Vegeta: only your father knows their names Gaki!!

Goku: hey let's spar!!

Then both saiyans when super Saiyan.

Y/n: let's do this!!

Y/n, Goku and Vegeta: HAAAAAAAAAAAA!!!

They all collided causing a huge shockwave. Y/n crashes to the build shocked how strong the two saiyans.

Y/n: very strong. Trained right?

Goku: yeah it was very long to achieve Perfect Super Saiyan Blue.

Y/n: Perfect Super Saiyan Blue?

Vegeta: yes that form is a gamble a high risk-high rewards type because it can cripple your body.

Y/n: I see but how can I achieve super Saiyan forms even with my chaos powers it would difficult.

Goku: training is what you need to achieve and master the forms.

Y/n: got it how long?

Vegeta: since your inner world is like the combination of Whis's Staff, Bulma's Gravity Chambers and The Hyperbolic Time chamber and here time is different.

Y/n: how much gravity in my inner world?

Goku: about 2,000 times more than earth's gravity but since your forms and yourself can handle it you need to use it to become stronger.

Vegeta: let's increase the gravity to 4,000 times.

The inner world's gravity increase was Y/n felt he was being pulled down but he gotten up.

Goku: come on Y/n let's train.

The three people went to Super Saiyan for some time.
(Timeskip)

Y/n was getting stronger, able to achieve all of the Super Saiyan forms even mastered Ultra Instinct with minutes.

Y/n: I felt much more stronger now!!

Goku: okay this is the final test.

Vegeta: we'll be fusing so be ready. But we'll be having some extra people to help us.

Then a fusion person and a boy who was wearing Goku's Gi appeared.

Y/n: such power!!

????: Hey name's Gotenks!! The Grim Reaper of Justice!!

Y/n: wait why I hear two voices at the same time?

Gohan: that's the fusion dance.

Y/n: Fusion Dance?

Goku: yes the fusion dance is when two people fused their bodies to become one powerful person but their is an 30 min limit which like this.

Both Vegeta and Goku begin the fusion dance.

Vegeta: FUUUUU!!!...

Goku: SSSIIIOOONNN!!!...

Goku and Vegeta: HAAAAAAAAAA!!!

Then their bodies fused to become as one as Y/n covered his eyes. The light fades away as he saw the fused saiyan.

????: I'm neither Goku nor Vegeta!! I'm Gogeta it's over Janemba, I'm come for you!!

Y/n: no way that's powerful!!

Gogeta: this Super Saiyan.

Gogeta: this super Saiyan 2!!

Gogeta: this Super Saiyan 3!!

Gogeta: this is Super Saiyan 4 the primal super Saiyan!!

Gogeta: AND THIS IS SUPER SAIYAN BLUE!!

Gogeta: get ready because I'm not holding back!!!

Gotenks: HAAAAAAAA!!

Gotenks: alright!!

Gohan: HAAAAAAA!!!

Gohan: show me what you got!!

Four of them charged as Y/n blocks each of their attacks. Then Gohan counters the block as Gotenks uses Super Ghost Kamikaze Attack.

Ghost Gotenks: Hahahahahaha!!! Hello!!

Y/n: what the!?

The ghost chases him down as Y/n quickly went to Super Saiyan 3. Then he punches one of them as they groan in pain.

Y/n: Got you!!

Ghost Gotenks 1:*chuckles*

Then it glows causing it to exploded as Y/n was send down to the roof.

Y/n: explodes when it makes contact!?

Gotenks: Hehahaha!!

Y/n:*growls* KAMEHAMEHA BARRAGE!!!

He shot barrages of Kamehamehas at the ghosts exploding them.

Gotenks: DIE, DIE MISSILE BARRAGE!!

Gohan: MASENKO!!!

Gogeta: STARDUST FALL!!!

All of the attacks were about hit Y/n then uses chaos control to stop it. Absorbing the attacks and time starts again, he sends the attack back hit them.

Gotenks: ow that hurts!!

Y/n: payback for that ghost attack!!

This continued for a long time in Y/n's Inner World.

(Timeskip)

Five fighters tired from the long fight, luckily Y/n regenerated his injures but slowly getting his ki/God Ki back.

Goku: you go back with your family Y/n.

Y/n: yeah, thanks for training me, that was fun!! I can't to fight again!!

Then everything went white....

Y/n:*groans* what the?

He looks around and freaks out that many of his friends were on his bed even his family where there.

Y/n: WHAT THE FUCK!?
