THE TRUE LEGENDARY SUPER SAIYAN [DBZA/DBS MALE READER INSERT]

THE NIGHTMARES

Y/N wakes up sweating before looking around and seeing that he's in bed with 18, he looks at the clock, seeing that it's only 3AM, he gets out of bed and heads downstairs before grabbing a cup and filling it with water before chugging the whole thing down, then a voice behind him says

18: "Y/N? What are you doing in here?"

Y/N turns around and sees 18

Y/N: "Uh... Nothing... Just... Thirsty..."

18: "Y/N, I can tell when you're lying... Tell me the truth."

Y/N: "Okay 18... The truth is... I've been having these Nightmares recently about when I was in the Frieza force... About all the plansts I've conquered... And all the innocence I've killed... I've killed Quadrillions of people... I'm... I-I'm afraid that I'm gonna end up doing it again... Like Black... He killed nearly all of the population of Earth... He made me think... What if

He looks at his reflection in the glass

Y/N: "I snapped and did the same thing... Killed everyone... And even killed... You..."

Tears flow down his face as he remembers facing Black(In this version, instead of Zamasu turning into Goku, he turned into Y/N)

(Flashback time)

Zamasu has pinned Y/N to the wall and is explaining how he took Y/N's body and says that he killed Y/N

Black: "What about 18 and Andria? N-NO! YOU DIDN'T DID YOU! YOU DIDN'T!"

Black: "Oh, but I DID!"

Then he stabs Y/N with a Ki blade but Y/N just looks Black in horror

(Skip to 0:38)

Y/N looks at Black before a huge Green Aura surrounds him and pushes Zamasu and Black back, Y/N looks at Black with hatred before the surrounding Area changes colors, Y/N screams in sorrow and his eyes turn red before expanding and his pupils burst out of his skull

A gigantic Green bubble surrounds Y/N before exploding, turning into a gigantic Green beam, Y/N rises out of it with Green hair before flying into the air and charging his energy, changing reality once more, the presence is felt so far out that Beerus himself, the one that's not even in this timeline, can feel the immense power, Vegeta looks at Y/N

Vegeta: "Oh no..."

Another Giant Green bubble appears around Y/N and he screams in anger before looking straight at Black and then Y/N starts to absorb surrounding Energy, but not just any Energy, the Energy of all the dead Gods that Black and Zamasu had killed, from  beyond the grave they are giving their power to the one mortal who can handle it all, the energy enters him and his hair starts to wildly change colors before eventually ending back at Green, trillions of Ki blasts expelled from his body as if they were bullets from a Gatling Gun, Black's outfit gets shredded to pieces when he blocks them all before the Green bubble around Y/N grows in size and destroys multiple buildings along with it, he charges towards Zamasu and Black

(End of Flashback)

18 has her hand around Y/N's back

18: "Y/N, you'd never do that. You're a good man, and you'd never snap, Black wasn't you, he was a god possessing your body. And you were able to beat him."

Y/N: "That's not the only problem... I... I'm Afraid!"

(GODDAMNIT! I'M GONNA CRY JUST BECAUSE OF THIS!)

He looks at 18 with tears in his eyes

Y/N: "Not for myself... But everyone here! I'm afraid someone I didn't kill will come for me stronger than me and kill you all... I..."

18 pulls him into a hug and he hugs her back, outside the sun rises and Y/N reverts back to his base form(He was in SSJ4 for the story

18: "No one's gonna kill us Y/N. You're the strongest man I know! I know you'll be able to stop them!"

She kisses him on the lips and continues hugging him
