Previously on "Dark Legacy"

The three saiyan's were stuck in place, stunned by the power Goten Black is releasing. Zamasu watch with a smile as he sees his pupil's hair growing longer.

"GGGRRRRRRHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHH

Goten Black screamed for a long period of minutes before stoping, his muscle grew, his hair was longer and spikier, his aura was flaring with sparks of electricity, his eyebrows were gone, and his power was ginormous.

Zamasu: "Marvelous! hahaha! much more powerful than what I expected!"

Goten Black: "Hehe" (points at himself as he became SSJ3) "Feast your eyes mongrels! for I am inevitable!"

Goten has gone far into his power, and transforming into mighty Super Saiyan 3 transformation. The big difference being the high amount ki and power Goten Black is showing is larger than when Trunks transformed into SSJ3 or when Goku went SSJ3.

Vegeta: "Get ready! HAH!" (transforms into Super Saiyan Blue)

Trunks: "Right! I can't lose this time! it has to end here! HAAAAAAAA!!" (transforms into Super Saiyan 3)

Goku: (looks at Goten Black) "I won't allow you to continue down this path Goten, I will save you no matter what" (clenches his fist and powers up) "HAH!" (transforms into Duper Saiyan Blue)

All three went full power, Goku and Vegeta's Super Saiyan Blue looked more controlled and powerful, and Future Trunks seems to have gotten better control of the power he unleashes in Super Saiyan 3. Goten Black power was equal to the two saiyans in blue, if they were going to win this fight, they would have to fight together.

Goten: "Save me huh? I don't need saving" (turns to his master) "look at this master, they're Ki has grown stronger since the last time they were here, shall we fight together master or would you like to observe?"

Zamasu: "I will observe for now, entertain me my boy"

Goten Black: "Hehe gladly" (turns towards Goku, Vegeta, and Future Trunks) "Alright fools, show me your motivation HMMM!" (powers up, his ki flaring with sparks of electricity)

Goten Black stares at Goku, Vegeta, and Trunks. Both sides stare at each other seriously until all four dash towards one another. The final battle begins now, Goten powers grows with every steps and our heroes most grow stronger if they wish to defeat his wrath.

Everything seemed quiet in the future, there were no explosion nor any sort of sound of fighting, screaming, or danger. We see Zamasu standing on the edge of a building, overlooking the desolate sight before him. The same old destroyed buildings, same old craters, same old trees that are still fresh and living, and same old things he once left as the were when he was Black.

Zamasu: "Aaah what wonderful evening . . . or is it afternoon? I can barely tell sometimes with how green the atmosphere is hmm I still wonder how it turned like that to this day, I don't remember really doing anything to it . . . . . you can come out now you know? it isn't wise to stalk on a god right?"

Zamasu turns around, only to be meet familiar sight that was covered by a cloak, but even though the individuals face was hidden, her long white hair was visible, and her staff was held by both her hands. The individual had a female figure and had light purple eyes.

???: "Ooooh~ I'm sorry~ did I disturb you mister god of justice?"

Zamasu: "Hmph! if you've come to belittle me than take your unnecessary humor some where else demon, I'm enjoying the fact that my student is demolishing these fools"

???: "Really now~? Then I guess I have more reason to stay hehehe~ I always love seeing him fight, but don't worry" (turns away) "I'll watch it on my own terms, good day"

Zamasu: "Wait"

???: "Hmm?"

Zamasu: "Why are you here? we informed you that this is something we shall do ourselves, you gave us this path and then I'll hold my end of the bargain, so what are you doing here?"

???: "Can't a girl just come out and make sure to see that their . . . hmm favorite and most lovable boy is fighting our enemies and making sure he shows dominance, plus this the perfect set up I need to gather more energy for Mira"

Zamasu: "Is that so huh? tsk, proceed on demon and don't come close to me hmph! your presence disgust me"

???: "The feeling is most mutual Zamasu" (disappears) "I would watch your next move if I were you"

As the woman disappears, Zamasu looks towards one of the destroyed buildings. Going towards it, we find that the interior of an apartment is surprisingly still intact and actually okay; That is until this happens. The interior of the apartment began to shake and some of the small things began to fall of shelf's while other objects began to crumble and break apart as out of nowhere.

"SMASH!!"

The wall was burst opened and coming out of the smoke in slow motion was Super Saiyan 3 Future Trunks whose face was grabbed onto by smirking Super Saiyan 3 Goten Black. Black tightens his hold on Future Trunks face and slams him against the wall first.

Then drags Future Trunks against the wall before throwing him out the apartment like a ball as he then does a front flip kick because Vegeta tried to surprise attack him, he lands the kick on the prince's chin as Goten Black lands his feet on the ground and spun kicks Vegeta once and then kicks him a second time with a ki blast that appears on his right foot. The result was Vegeta getting launched out the room. Goku appears out of nowhere and tried to shop Goten Black, Black blocks the karate shop and goes to knee Goku, but he blocks it and starts throwing quick punches that Goten Black dodges first before appearing a smaller version of his ki blade and tries to slash Goku with it, Goku sees this and lean back to dodge the attack. When Goku leans back up he's meet with a strong stomach punch that makes him release some air.

Goku: "GAAAH!"

Goten Black: "Heh"

Goten Black drags him out of the now destroyed apartment, with his fist still on Goku's stomach, and then launches him towards the ground below. Goku skids on the ground and rolls before pushing himself up and lands on his feet, but he still feels the pain from the punch as he places his hand on his stomach. Goten Black laughs before dodging a surprise from Trunks, he tried to slice Black, but missed and was meet with punch to the face, Future Trunks doesn't give up and fire a ki blast at Black who deflects it before appearing his ki blade. He lunges towards Trunks and tries to slash him, but Trunks blocks his blade with his own sword and both tried to fight for dominance until Goten Black changes his ki blade into a sphere that traps Trunks inside.

F. Trunks: "What the—!?"

Goten Black: "FAAALL!!!"

Goten Black motions his hand downwards which then sends the trapped Future Trunks downwards as well as when the sphere impacts against the ground, it explodes. Goten Black then turns around and collides fist with Vegeta, both grit their teeth as they fight for control until they pulled away from one another and began to fly around the air while clashing with one another. In the sky you could see a yellow light and Blue light circling around one another before colliding with one another four times before coming in crashing against the ground below. Hands locked on against one another, their Ki's flaring, and their faces only show anger and determination, but they soon let go of each other and jump right in into one another with a barrage of hits that land on one another.

Punch after punch, fist after fist, and knuckle hits knuckle, both Goten Black and Vegeta threw a multitude of punches that clashed in between them. That is until Vegeta was able to slip in a punch that lands on Goten Black's face, pushing Black back a little and then raising his right arm up and aiming it at Black and charging up an attack.

Vegeta: "Big Bang Attack!"

A giant blue sphere appears and Vegeta fire it at Goten Black, he catches the attack and infuses it with his own Ki, making it bigger and strong as he redirecting it back to Vegeta, who's eyes widen when seeing his own attack being turned against him. He catches the attack too, but is suddenly getting pushed by it, so he plants his feet on the ground and tries to hold back his attack. Goten Black smirks and fires ten ki blast at the ball of ki that is holding Vegeta, the ki blast miss purposely and stood motionless behind Vegeta. Vegeta looks back and sees them, making his eyes widen again when Goten Black back his hand which in turn gives the order for the ki blast to attack Vegeta, who's eyes widen is pummeled by both his own attack and the ki blast.

Goten Black: "Hmph! pathetic"

Goku: "HAAAAAA!"

Goten Black blocks a punch from Goku and then ducks under a kick from Future Trunks as he then drops down with his hands on the ground and his feet in the air, kicking both Goku and Future Trunks  at the same time before launching Goku away with a ki blast being shot out of his foot. Goten Black then spun around on the floor before sweeping Trunks feet, and then Black then launches him away with energy air slash that was shot out from his left leg. Future Trunks was able to block the attack on time, but he's getting dragged away by the energy air slash until he increases his power and cuts the attack in two. He sheaths his sword and quick motion with his hands before firing a big version of his attack Burning Attack, Goten Black sees this and appears his ki blade, he uses it to block the attack and then cut it in haft as it exploded behind him.

Goten Black: "Let's go Trunks!"

F. Trunks: "Coming right at ya Goten!"

Both dash towards one another and clash sword and blade as they tried to overpower one another until Goten Black pushes Trunks sword away and kicks him back. He extends his right hand out and appears a second ki blade, smirking sinisterly at Trunks, who is surprised he made a second ki blade when he would normally just use one.

Goten: "They are not as sharp when I'm in rose, but they are enough to cut you all down!!"

F. Trunks: As if I'll let you! I will defeat you!"

Both warriors dashed towards one another before stoping right in front of each other, soon they began to move at fast past with their sharp weapons and clashed with one another.

Ki blades before one sword, Goten Black and Future Trunks moved in a fluid motion against another, but as the clash continued on, Goten Black was starting to become faster and swung his arms with more strength that was making it difficult for Trunks to keep up as he went to blocking Black's attack until he received a cut from one of Goten Black's ki blade. Caught by surprise, Goten Black uses this moment to push Trunks sword aside and then kicks the time traveler on on the chest, pushing him back.

Goten Black: "Take this!" (extended his right hand to the side and the ki blade changes into a disc that spins like a saw) "Destructo Disc!"

Goten Black throws the disc which then splits into four more other disc that go after Future Trunks. The target in mind was surprised to see that Goten Black knows that technique, but he soon goes back into reality and dodges two of the Destructo disc and cuts down the third one. The last one was controlled manually by Goten Black as it makes it miss turn to dodge Future Trunks sword, then controls the other two that missed to circle back with the fourth one. Trunks fire ki blast the Destructo Discc destroying two that make a smoke when destroyed, out that smoke comes the last Destructo Disc. Goten Black, with still one ki blade on his left arm, charges towards Trunks who now has to decide which side to for, that is until a ki blast out of nowhere destroys the Destructo Disc, and then Goku comes flying in and drop kicks Goten Black towards somewhere else. Goten Black skids on the ground before stomping his feet on the ground and launching himself towards Goku with a punch that his father blocks as he then receives a knee to his stomach and a sledgehammer that slams him against the ground.

Goku: "Enough is enough Goten! surrender! . . . . . . . and let me make things right"

Goten Black: "Tsk! ggggrrr" (starts to push himself up until he stand up and stare at Goku with a glare) "never" (throws a punch)

Goku sighs and blocks the punch and then throws his own punch, which hits Goten in the face and makes him stumble backwards until Goku fires a point blank ki blast that launches Goten Black back. Goku stares at where Goten Black is in sadness, a solemn look that changes to surprise when he sees Goten Black disappear and appear in front of him again as Goten Blavk uppercuts Goku strongly to the sky and then places two fingers against his forehead. Using instant transmission, Goten Black disappears and then reappears behind Goku.

He kicks Goku and launches him towards some buildings as he then uses instant transmission again and appears right above Goku, puts the back of his hands on his forehead and charges up an attack. Trunks in the distance looks at the attack he's going to use and is surprised by it.

Trunks: "And that's—!"

Goten Black: "Masenkoooo HAAA!!!"

The energy wave hits Goku, devours him, and destroys everything that's around him, Goten Black continues to fire his attack until Vegeta comes in and punches Black in the face. This stops the attack and make Goten Black look at Vegeta angrily.

Goten Black: "That was very uncalled for Vegeta, you'll regret that"

Vegeta: "The only one regretting anything here will be you Goten, now come at me hybrid"

Goten Black: "With pleasure mongrel!!!"

Goten Black and vegeta launch at each other a collided fists, then collided legs, and then they collided their shoulders, the ki that surrounded both of them flares again as they tried to push on another. Then they disappeared and appeared a few away from another, charging up an attack.

Goten Black: "KamehameHAAAA!!"

Vegeta: "GALICK GUUUN! FIRE!!"

Two purple beam collide with one another, and so they enter a beam struggle scenario where only the strongest one would overpower the other. Goten Black and Vegeta screamed in rage and determination and seemed evenly match until Future Trunks appears out of nowhere and tries to finish off Goten Black right there in the beam struggle. This makes Goten Black smirks as when the sword was merely inches away from him, he disappears before Future Trunks could strike him. With him now gone, Vegeta's Galick Gun pushes on forward and targets Trunks, who turns around and reacts too late. The Galick Gun hits Future Trunks and launches the time traveler away, seeing this Vegeta stops his attack and sees from the corner of his eye a glowing black and purple sphere in someone's hands. He turns to see Goten Black charging up another Dark Kamehameha, not being able to react on time Vegeta is hit point blank by the attack, resulting into an explosion that covers the sky where both warriors are. Smoke covered the sky, and out of that smoke comes out the prince of all Saiyan, battered and defeated, he falls down to the ground. 

Goten Black: (looks down at Vegeta with a satisfied smile) "Blame your son for that one"

Goku: "Goooteeeen!!"

Goten Black: (turns to see Goku flying towards him) "Alright then, let's end this!!" (dashes towards Goku)

Both father and son dash towards one and collided against one another, creating a shockwave that cracks and breaks everything that was around them. Goku then uppercuts Goten Black and grabs his right leg, spinning around Goku throws Goten Black towards the ground and then flies after him. Goten Black lands his feet on the ground and blocks Goku punch, he then grabs his father and slams him against the ground, and then appears a ki blade and tries to stab Goku, who eyes widen as he rolls out of the way and kicks Goten Black before getting up.

Goku: "KamehameHA!!"

Goku fires his signature kamehameha at Goten Black, he recovers from the attack and sees the energy wave heading for him, so dodges the attack and fires a ki blast at Goku. The Saiyan from earth catches the ki blast and throws it back stronger towards Goten Black, but the powerful haft breed catches it too and splits it into six more ki blast that he launches back at Goku.  Goku is hit by all of the Ki blast that were launched at him and smoke covered where he stands, when it disperses he looks around and doesn't find Goten Black until he looks up. Up in the sky was Goten Black and he was charging another Dark Kamehameha.

Goten Black: "HAAAAA!!!"

Firing a powerful version of his own Kamehameha, Goten Black fires a Dark Kamehameha that devours Goku. Inside the blast, Goku was quick enough to create a Ki force field that protects him from the attack, but it was looking that it wasn't going to hold on for much longer.

Goku: "Tsk! I have to break my limit and use the Kaioken!" (clenches his fist and powers up, his blue aura flaring around him) "KAIOKEN!!"

Goku ki flares with the colors blue and red as he screams a warriors cry and overpowers Goten Black's attack, destroying it in the process. With the Dark Kamehameha now destroyed, Goku looks up towards Goten Black with an angry expression.

Goten Black: "Wha-What!?"

Goku: "I will defeat you Goten! HAAAA!!"

Goku flies up to Goten Black with a fist clench and lands a powerful punch against his son's gut, making Goten Black release hair, but Goku wasn't done yet. Goku launches a barrage of attacks that hit Goten Black in multiple areas until he finishes the attack with a punch that launches Goten Black towards the ground. Goten Black lands on the ground and creates another crater in this apocalyptic world, Goten Black groans and rubs his left cheek as he slowly gets back up and sees Goku staring down at him.

Goten Black: "Bastard, don't you dare look down at me!!" (goes back to base form, falling onto one knee) "darn it! guess you tired me out heh good job, lucky bitch"

Goku's red aura disappear and he just descends down with his hair still in Super Saiyan Blue, he lands on the ground a few feet away from Goten Black and stares at his son with a solemn look. Goten Black, who had battered clothes and was in a tired state, stares back at Goku with anger and distain.

Goku: "Let me help you"

Goku takes one step forward, but is stop when he has to dodge a small, thin, and long beam that came from Goten Black. Goten Black had his right arm raised, with two fingers pointed towards Goku.

Goten Black: "You stay right where you are Son Goku, your lucky I missed on purpose" (lowers his arm) "that attack is similar to one Frieza's, it would have pierced your heart and killed you kn the spot"

Goku: "Is that so hmmm your weak now, you've used to much ki in Super Saiyan 3 that you barely have anything left now"

F. Trunks: (lands beside Goku, back now in base form) "Guess you made the same mistake as me Goten"

Goten Black: "Quiet you spoiled brat! unless you want another beating"

Vegeta: (descends down) "With your state, I don't see you beating anyone here kakarot's brat" (lands beside Trunks and hands his son a Senzu bean, then gives Goku one)

Goten Black: "Hehehe oh you have no idea what you're in for Vegeta, I have more surprises just right around the corner" (smirks) "ones that reveal more of a saiyan's power"

Vegeta: "Hmph! your bluffing"

Goten Black: "Am I? am I really Prince hehehe"

F. Trunks: "Even if it were true, who said we would allow you to gain even more power?"

Zamasu: "And who said I would allow you to stop him Trunks?"

Zamasu appears right in front of the trio with a ki blade on his right arm as he lunges forward towards the Future Trunks. Zamasu goes for the kill, but Future Trunks was fast enough to raise his sword and block Zamasu's attack. Though Future Trunks sword shakes as he feels like he's getting overpowered by Zamasu, who smirks when seeing this sign of weakness.

Zamasu: "Still too weak Trunks"

F. Trunks: (powers up to SSJ 2) "Not for long!" (pushes Zamasu back and fires a ki blast) "take this!"

Zamasu sees the ki blast and easily cuts the attack and then sees Goku charging at him with rage, he disappears his ki blade and blocks Goku's fist.

Zamasu: "Hmm I can't help, but think that you hate me for some reason"

Goku: "You will hate for what you did to Goten!"

Zamasu: "Oh please, I haven't done anything to the boy and all I've really done is show him a path were he will stand on top above all, above every Goku, and most certainly above you"

Goku: "I know you're hiding something! I will not let you corrupt him more than you already have!!"

Zamasu chuckled and in a split second was able to knee Goku on the gut before he could react, then he ki blast Goku away and turns to Vegeta. The prince charges at Zamasu at fast speeds, but Zamasu was faster and stronger as he disappears and reappears in front Vegeta.

Zamasu: "Foolish!"

Zamasu lands a strong stomach punch on Vegeta, so strong that Vegeta reverts back to base form even after he just presently ate a Senzu bean.

Vegeta releases air from his lungs and vomits out a bit of saliva before getting launched towards some of the destroyed buildings.

Zamasu: "Well that was certainly easy"

Goten Black: ". . . . . Why the heck were you on the sidelines this whole time master"

Zamasu: "Haha come now my student no time to be feeling ungrateful"

Goten Black: "Yeah yeah"

F. Trunks: "HAAAA!" (powers up to SSJ 3) "Zamasu! Goten!!"

Goten Black: "Shall I try our theory"

Zamasu: "Go for it"

Goten Black: "Alright, cover your eyes master" (puts his hands on his both sides of his face) "Solar Flare!"

A blinding light hits Future Trunks in his eyes, making him temporarily blind as Goten Black then appears a white orb on his right hand and then aims it upwards to the sky. He throws the orb to the sky and smirks when he feels its waves already having effect.

Goten Black: "Now let's set you free" (lifts up the lower haft of his gi, and out comes out a saiyan tail) "I've been waiting for this moment" (powers up to SSJ 1 and looks up at the white orb) "burst open! and mix!!"

Zamasu: (looks up with a sinister smile) "Excellent!"

F. Trunks: (rubs his eyes and looks up at the sky) "What is that!?"

Goku: "Huh?" (weakly looks up, his eyes widen) "that's...!"

Goten Black stares at the ball calmly in Super Saiyan until his head snapped and he began to breath heavily. He clenches his fist as he's heavy breathing increased, but so did his size as his muscle began to grow, and so did he's body, his clothes began to slowly get turned apart and hair began to appear all over his body. Goten Black started to change into one of the Saiyan's transformations when they have a tail, a Great Ape, but with no moon he created an artificial one that he found out his grandpa created.

Trunks: "He-He's changing"

Goku: "Trunks! destroy the white orb!"

Trunks: "Ri-Right!"

Trunks charges up a ki blast to fire at the artificial moon, but Zamasu appears in his way and attacks before Trunks could fire his ki blast.

Zamasu: "Do not disturb him!!"

Zamasy appears a halo behind him and fires multiple red ki blast at Trunks, who gets hit by all of them and forced out of Super Saiyan 3. Goku tries to stand up, but Zamasu appears above him and his feet onto Goku's back, which in turn forces the Saiyan from earth to remain on the ground.

Zamasu: "Oh no no no don't look away Son Goku" (kneels down and grabs Goku's head and face, forcing him to watch as Goten Black turns into a Great Ape that started to slowly glow golden) "Watch as your son unlocks something you Saiyan's never truly committed to achieving, a level beyond that of your supposed last Saiyan form, that repulsive Super Saiyan 3"

Goten Black in Great Ape form roars as the same golden aura that surrounded a Saiyan in Super Saiyan began to on Goten Black, his brown fur changed to golden and the top of his head grew spiky a hair style that was similar to his SSJ 1 hairstyle.

The Ape gritted his teeth, it look to be concentrating and angry with how red his eyes were. Goten Black clenched his giant fist and let out a powerful roar that shook everything around him. His aura flared with sparks of electricity now surrounding him, it is as if this Golden Great Ape form just went from Super Saiyan 1 to Super Saiyan 2.

"RRRROOOOOOOAAAAAAAAAARRRRR

Goku: "Tha-That form"

Zamasu: "Do not worry, unlike you fools who take their time mastering this form, Goten will have full control of it in seconds" (chuckles) "Saiyan legends for told of this state, saying it is a gateway for even greater power that Saiyan could reach"

Goku: "Gate...way?"

Zamasu: "Why yes, this form is powrful, but it is only a gateway towards his real power" (stares determinedly at Golden Great Ape Goten Black) "a saiyan true primal form!"
