Y/n's POV
" Y/n! Y/n wake up! " I hear someone yell.
" Oh, Kami! Not my boy too! " I hear someone else yell.
As I slowly open my eyes, I see Mother, Aunt Chi-Chi, and Videl standing over me. Then I remember Buu and immediately stand up.
" Gohan...! Gohan! Where's Gohan?! " I yell out, panicked.
At this, Chi-Chi tears up.
Chi-Chi: Gohan... They think Gohan is dead.
" Wh-what...? Dead?! " I yell out again.
Bulma: Y/n, your father... He's...
" They think he died too?! "
Bulma begins crying and hugs me tightly.
Bulma: He's dead!
" Father... And Gohan... " I mumble, my mind going blank.
???: Y/n, we need to train.
I look up and see Uncle Kakarot.
" What? "
Goku: ... Now. It's important that we do this as quickly as possible.
I nod and Mother lets go as I follow Uncle Kakarot to the Hyperbolic Time Chamber.
Once we enter the Chamber, Uncle Kakarot immediately turns around.
Goku: Y/n, right now... You're our only hope against Majin Buu.
" What? But you're here- "
Goku: Not for long I'm not. Which is why we're training now. I think you can reach it.
" Reach it...? Reach what...? " I ask, confused.
Goku: Super Saiyan 3.
" Super Saiyan 3?! "
Uncle Kakarot nods and transforms into a Super Saiyan, then a Super Saiyan 2 before powering up more and letting out a guttural roar. His aura engulfs him and as it dies down, I can see he now has long hair and no eyebrows, was more muscular, and had pupils again.
" Wh-what power...! You're even more powerful than Buu! " I exclaim.
Goku: Trouble is... I can only maintain this form for a short amount of time... And it'll eat away at the time I have left. So now that you know what you're shooting for...
He reverts to his base form and nods.
Goku: Show me your full power.
I nod and transform into a Super Saiyan 2, then power up to my max.
Goku: Not bad... Your Super Saiyan 2 form is even stronger than Vegeta's.
" It is...? "
Uncle Kakarot nods and transforms into a Super Saiyan 2.
Goku: Now, show me what you're made of!
He dashes at me and throws a punch, which I barely dodge before he kicks me away, then fires a Ki blast at me, which I counter with a Ki blast of my own before rushing him and throwing a right hook, which to my astonishment, actually connects and knocks him backwards.
Goku: Pretty good.
He disappears from my line of sight and I sense around for him, just barely dodging a punch from my side before I kick him in the face, sending him flying.
I follow up by rushing him and punching him repeatedly before ending my combo with a drop kick. He stops himself and launches a flurry of Ki blasts at me, which I dodge before charging up a Ki blast my own, the energy in my hand rapidly growing before I launch the attack.
" Big Bang Attack! "
Uncle Kakarot fires a Kamehameha wave in response, but by the time he's fired the attack, I rush him and punch him in the jaw.
Goku: Ngh... You're almost there, I can feel you reaching the ceiling of Super Saiyan 2! Now...!
He powers up into a Super Saiyan 3 again and punches me away.
Goku: If you don't want to be beaten down, you'll have to surpass yourself! Go even further beyond!
I wipe sweat off my face and rush him again, only to be punched in the stomach, making me double over and cough up saliva before I'm kicked away. I barely stand up and pant heavily, then I feel something inside me break and I let out a guttural roar as my aura engulfs me, blocking my vision. As my aura dies down, I see Uncle Kakarot smirking.
Goku: I knew you could do it... That's it, Super Saiyan 3.
I look down at my hands and I clench my fists a few times as I get used to the sheer power.
" This power... This is... "
Goku: Don't overdo it though, I've had this form for a little bit, but I've only used it today. That's why you're gonna stay here and master it. You can do it, you have to.
" ... Right. For Father... For Gohan! "
Uncle Kakarot reverts to his base form again and waves as he leaves.
" So... This is Super Saiyan 3. With this... I'll make Buu pay for what he's done. Just you wait, Majin Buu!"
