In this what-if, the Goku from Dragon Ball Super: After Broly will swap places with Dragon Ball Aftermath: The Sequel's.

Part One

There is a glitch in the realities that causes Goku from Dragon Ball Super: After Broly to swap places with his counterpart in Aftermath. What will happen to our heroes? In After Broly, the fight between the heroes and the evil gods has just concluded with Vegeta winning the battle using his Primal Instinct transformation.

In Aftermath, Abysus's return would have ended with Vegeta entering Super Saiyan White and Goku entering Ultra Instinct Stage Two. They would have fused into Vegito to kill Abysus once and for all. Next would have been the Broly arc for them in the original, but in this scenario, it's different.

I am going to go over the scenarios. This is going to be a very fun and interesting one to do. The first swap I will go over is Goku from After Broly going into Aftermath.

I will try to make this as easy to understand as possible. Just imagine the Goku being the one from the current FanFiction I am writing.

Without knowing, Goku and Vegeta from Dragon Ball Aftermath are sent into Dragon Ball Super: After Broly.

Goku suddenly finds himself in the Hyperbolic Time Chamber after resting from the evil god fight in his reality. He gets into his fighting stance, expecting an enemy to pop out and fight him.

However, nothing happens. He'd also realize he is in Ultra Instinct, tired. He would have to find out what happened tomorrow, or however time passes in the time chamber. He climbs into bed, falling asleep.

He leaves the lookout and goes to Mr. Popo and Dende. "Hey uhh... What's going on? Why was I suddenly teleported to the Hyperbolic Time Chamber?"

The two look at him with puzzled expressions on their faces. "Perhaps you used your teleportation technique while sleeping," Popo says, and Goku snaps, thinking he is right. "Oh, you're right! Huh, how silly of me! Anyway, I'm going to go train and get Vegeta's new form. See ya!"

He flies off, and Dende and Mr. Popo look at each other. "What's Vegeta's new form?" Dende asks Mr. Popo. Popo just shrugs.

Goku flies down, feeling something isn't quite right. He goes to Bulma's place to eat food and meets Beerus and Whis there. He begins to eat, and Whis asks him the exact same question he asked before he met Broly. "So tell me, Goku, Why do you seek even more strength than you have already?"

Goku looks up at him, puzzled. "Didn't you ask me that before, Whis, or am I just going bonkers?"

Whis raises an eyebrow. "I don't believe so, but maybe I forgot myself. Anyway, what makes you think you could surpass Ultra Instinct Stage 2? It is the maximum level of even an angel."

Goku would be even more confused. "What's Ultra Instinct Stage Two? You mean Ultra Instinct, orr.."

"It's the form you were using against Abysus when he returned," Whis replies, rolling his eyes. "Don't you remember?"

"You're talking about the evil god battle when Vegeta used his new form to beat them, right?" Goku asks, getting a slight headache. "Wait... Isn't that the leader of the evil gods?"

Whis takes a long pause, staring at him. "I do not recall Abysus ever having evil gods. What do you mean 'leader'? Are you alright?"

Without another word, Goku gets up and walks away. He'd have to talk to Whis later and figure out what is going on. He goes over to Vegeta, who is training in the gravity chamber in Super Saiyan Blue Evolution. "Hey, Vegeta! You notice anything out of the ordinary?"

"Yeah," Vegeta grumbles, "you." Goku sighs. "I didn't mean in that way, Vegeta! What's all this Ultra Instinct Stage 2 stuff that Whis is saying?"

Vegeta pauses, walking over to him. "Your power... It's different than before. You aren't the Kakarot I know, are you? Are you Zamasu?!" He grabs him by the collar, and Goku raises his hands to stop him. "Woah, Woah, Woah! Come on, Vegeta! You too? What's going on here?"

Vegeta scoffs, letting go of him. "With my luck, you're hiding a new form from me. Soon, I will unlock Super Saiyan White and surpass you once again!"

"I-" Goku decides not to question him and whatever the heck Super Saiyan White is. It must've been the name that Vegeta gave his new mysterious form.

Meanwhile, a familiar-looking ship is heading toward the Earth, as it enters the atmosphere. It hovers toward the Arctic.

"Kakarot, do you feel that Ki?" Vegeta asks as he looks up to the sky, expecting to see something crashing down. "That is a massive Ki."

"This energy is very similar to Broly, but... different," Goku replies as they both notice the ship descending on the land. They launch off toward it, soaring through the sky at crazy speeds.

They land in front of the ship, and the hatch opens, as two forms walk out, one of them are large and bulky, and the other is an old man. After them, a familiar figure follows them, as they step into the light.

"Hohohoho!" Laughter is heard, as Frieza steps in front of the two people. "It has been a while, Son Goku and Vegeta!"

"Damn it, Frieza! What do you want?" Vegeta yells. "Are you perhaps here with your daddy to destroy Earth again?"

"No need to have a bad attitude, Vegeta. I have found two surviving Saiyans who have escaped the destruction of Planet Vegeta," Frieza replies as he regards the two Saiyans coldly.

Goku would be overwhelmed by what is happening. "Wait, this already happened... Broly! Why are you with Frieza again? How are you not converted any more? Why is that old guy alive again? I thought this was finished!"

Vegeta stares at him in silence. Paragus walks forward, clenching his fists. "How do you know our names, son of Bardock?!"

Broly pauses, more confused than angry. Goku grunts, sweat going down his face. "Something's not right... Their energies are different... Vegeta! What is happening? What about our fight with Cell, or Beerus's evil counterpart, or Omesus?!"

"Cell died ages ago!" Vegeta replies, getting a little irritated. "Who the hell is Beerus's evil counterpart, and WHO THE HELL IS OMESUS, KAKAROT?!"

Goku pauses, then he realizes that this really is not his world. He'd have to try and get back to his world later. Right now, Broly, Frieza, and his men are threatening Earth... again.

Goku slowly walks up to Broly, and Paragus would try to stop him, but he walks around his father to avoid angering Broly. "Broly, it's me, Kakarot. You do not have to fight if you don't want to. You don't have to listen to what they say. Frieza is using you, and he plans to kill your father and force you into a rage so he can use you to kill us."

Everyone, even Frieza would have fallen into silence. Broly would have never trusted the tyrant, but only followed his orders since his father told him to. He looks toward his father, hesitant.

Paragus turns toward Frieza, then comes to his senses. "What are you waiting for, Broly?! DO IT!"

Broly would have no choice but to oblige. He roars, wind shooting from him. He launches toward Vegeta, bringing back his fist.

Goku roars, entering Super Saiyan Blue Four to block his punch, shocking Vegeta. "What...? What kind of form is that?!" He'd now realize that Goku has his tail again. "Why do you have a tail? What is that form, Kakarot?!"

He and Broly would be in a hand lock, pressing against each other. Goku would have the upper hand against him in his state, as he prevents him from moving. "Broly, we've met before in a different world. Trust me, your father is using you. Frieza is using you. Turn back, it's not worth fighting. Fighting is not what you want."

This time, Broly would listen to Goku, due to Goku knowing all about him at this point. He turns toward Frieza, squinting at him. "So, it's true..."

"Broly!" Paragus yells, getting the electric shock button out of his pocket. "Kill them right now, son!"

Broly walks past him toward Frieza, whose smile fades. "I don't want to hurt you, father. Stand aside."

Paragus growls as he presses the button, but rather than Broly getting the electric shock, it's Paragus. He grabs his neck, yelling in agony, as he manages to press the button to stop it. He'd see that Vegeta had been able to take off Broly's collar and put it on him.

Frieza and Broly walk toward one another. "Well, well... I must say, I am not surprised by a brute, worthless monkey like you turning on me. I'll just have to kill you and your old man painfully."

Saying that last bit was a huge mistake. Immediately, Broly's hair spikes up, and he roars, a green aura shooting up around him. He enters his Ikari form, slamming a punch into Frieza's gut.

Frieza coughs blood, as he is sent crashing through mountains, leveling the landscape. He'd no longer have limits to his power. Frieza yells, a golden aura flaring up around him. "You worthless SAIYAN!"

He launches toward Broly, and the two go back and forth, clashing blows. Frieza lands a punch on Broly's face, pissing him off. He knees Frieza in the chest, then mauls him on the neck, making his eyes go blank for a second.

Frieza is sent crashing into the ground, panting. He then breaks into a smirk. "Hohohohoho!" He gets up, brushing himself off. "If I were as weak as I used to be, I would have certainly died from that." He looks up, smirking. "Well then, I guess it's time to show you a new form I have recently acquired!"

Frieza roars, as his body flickers a brighter color, his body turning whiter, and more clear, as his eyes glow a bit. He yells loudly, lightning crackling around him.

"Behold! My shiny form! I call it my diamond form," he said. "You will stand no chance against me, for I am Lord Frieza!"

The ground glows beneath him, as he launches up at crazy speeds, shattering the ground.

Vegeta grunts, sweat going down the side of his face. "I knew it... He has a new form!"

Frieza roars, spin kicking Broly to the ground, causing a massive crater to form. Broly gets up, his energy continuing to rise. Frieza chuckles, as he points his finger toward Paragus, charging up a death beam. "Watch closely, worthless monkey."

Goku zooms forward at full speed, a bright blue trail following him. Just as Frieza launches it, Goku grabs Paragus and tackles him, the beam piercing his arm. "Tch!"

Seeing his father almost die, Broly lets out a roar of rage, his hair standing up even more. It flashes yellow, as a giant green pillar of energy shoots from him, lighting up the sky.

Paragus would be in complete shock. "Why... Why did you save me?"

Goku glares at him, as he shoves him back, sending him falling onto a clump of rocks. "Don't ever manipulate your son like that again." He walks off toward Broly, cracking his knuckles.

Broly zooms in front of Frieza, his aura sending him exploding back. Broly knocks him around like a ragdoll, then slams him on the ground. He prepares to finish him off with a beam, but Goku shoots up at the last minute and wraps his arms around him and pulls him back, causing the blast to be shot upward into the sky.

Broly grunts and he roars, starting to break out of Goku's restraints. Goku yells as he begins to glow pink, shocking Vegeta even more. "KAIOKEN TIMES TWENTY!"

Goku does lose against Broly due to never gaining the Angelic Boost from Whis. He and Vegeta desperately work together to try and subdue and calm him down.

Broly turns around and sees Vegeta, his hair, irises, and eyebrows were white. A large white aura was around him. "It looks like it is over for you, Broly..."

Vegeta was in Super Saiyan White. He is in the exact same form he had unlocked in a fit of rage against Abysus.

Broly turns around, twitching, as he launches off at Vegeta. The two begin to clash, their powers about equal to each other, as their exchange of punches cause shockwaves and electricity to shoot off in different directions.

Goku watches in awe at the power of Vegeta. "Wow, this reality is insane... Vegeta is so much stronger than me here. I bet he's at the level of Whis."

"I will put an end to you!" Vegeta yells in rage, as he begins to push Broly back a bit, throwing punches into his gut and face. Broly yells, as he begins to push Vegeta back, as they continue to clash. As they clash kicks, punches, and headbutts. as each exchange causes holes to appear in the ground below them.

Meanwhile, Goku gets up, struggling, watching the fight. "So that is Super Saiyan White... That Ki is so extraordinary. In a way, it is similar to Vegeta's new form, but... it's not."

Vegeta is punched in the gut, as he flies back. "FINAL FLASH!" He roars, as he launches a gigantic Final Flash at Broly, who is directly hit by it, and is launched into the rocks right by Goku.

"Woah!" Goku says in shock. "That was close!"

Broly sees Goku and launches small, green blasts at him, as Goku tries to block them, but is being pushed back.

He flies around Broly, trying to land hits, but Broly grabs his arm, throwing him toward Vegeta, causing them both to fall to the ground.

"Damn it, Kakarot!" Vegeta yells. "You just had to get in the way!"

"I'm trying to help, Vegeta!" Goku replies. "It's the least I can do!"

"You are only making things more of a nuisance for me!" Vegeta argues back.

While they are distracted by the pointless arguing, Broly launches after them. He punches them both in the guts, causing them to cough blood and get launched back.

"Look what you got us into, you idiot!" Vegeta yells at Goku. "Guckk!"

Goku sighs, getting up. "Vegeta, we both know I'm not the same Goku as the one here, but we have to cooperate." He pulls out Potara earrings from his pocket. "I had these ready for my next battle in my world. We need to fuse and subdue him."

Vegeta grumbles. "Fine, only because you are a weaker version." The two put on the Potara earrings and get drawn toward each other, sending a bright light across the multiverse.

Vegito opens his eyes, and he'd be in Super Saiyan Four, but he'd have glowing white hair, eyebrows, aura, fur, and tail. He'd be in Super Saiyan White Four, an undiscovered form.

Broly roars, launching at him at full speed. He swings a heavy punch, but Vegito smirks, blocking it with his finger. A short fight happens, but Vegito is far stronger than Broly is.

He brings back his fist, roaring. He covers it in Ki, slamming it into Broly's gut. He is immediately knocked unconscious. Vegito carries him over his shoulder, walking away from an injured Paragus and Frieza.

Years later, Goku would continue to train, having explained the situation to Whis, and he gave him an Angelic Boost. He'd remember the Ki that his Vegeta was radiating off when he used Primal Instinct.

He got training from Whis to obtain Ultra Instinct Stage Two, and with Whis's advice to use full power while suppressed at the same time, he'd be able to improve his Ki control.

Eventually, he'd be able to get a basic understanding of Primal Instinct, which is Angelic Ki plus Super Saiyan in his reality. If he could combine it with Ultra Instinct Stage Two...

Daishinkan does have the talk with the gods, and he is informed by Whis that Goku from a different reality has somehow replaced the one here. This leads Daishinkan to believe that their Goku is in another reality as well, but he doesn't know how to get him back.

Soon, Omesus does arrive. However, things would not be the same for him as in the original story.

They look up at the sky just in time to see a figure flying toward them. The figure reminded Goku of how his brother Raditz looked, but he was much more muscular, and his hair was gray instead of black.

"So," the figure said, "I see my kin have evolved to be stronger than I first thought..."

"Kin?" Vegeta asks. "As in..."

"Yes..." the figure replied. "I am the father of all Saiyans. Lord Omesus..."

Vegeta is shocked to hear this, but Goku immediately knows what he was going to say. "So, you're not so different from my reality, only power is the difference."

"I am disappointed that you all had to end up like this," Lord Omesus says. "You all were supposed to be prideful, merciless... And yet you are living on a planet like Earth... The one I visited tens of thousands of years ago. I hid there for a little while..."

"Don't underestimate us!" Vegeta yells. "It will be your downfall!"

Lord Omesus chuckles. "The last time I saw your race, was when you all turned into the Oozaru. Such a low level of power. I would be surprised if you never managed to acquire true Saiyan power."

Oh, we did!" Goku says, smirking. "We have approached levels far beyond that." Goku roars, his muscles bulging, as he transforms into a Super Saiyan.

Lord Omesus is silent, then he laughs heartily. "That is how my race turned out?! It seems ever since I created all of you, the power has been diluted. That is not even close to the true potential of a Saiyan..."

"How about you fight us, and we will see what we can do!" Vegeta says as he transforms into a Super Saiyan as well.

Lord Omesus uncrosses his arms. "Choosing to fight is a foolish choice, but very well."

Goku and Vegeta roar as they launch at Omesus, throwing punches at his chest, but he is not even budging a bit. He looks up at them, chuckling.

Lord Omesus smirks, as he throws punches at both of their chests, causing them to cough a lot of blood and be sent into space. "Pathetic, that is your true power?!"

The fight goes the same as in the original until Goku enters Super Saiyan Blue Four.

Goku roars a bright blue aura surrounding him. The ground cracks under him, as glowing blue fur grows on his body, and he enters Super Saiyan Blue Four.

Omesus is silent, then laughs. "What kind of transformation is that? It looks-"

Goku launches at Omesus insanely fast, then punches him in the face, causing him to skid back very slightly. Omesus wipes the blood off of his cheek, as he looks at Goku, irritated.

He roars, as he launches a massive energy blast. It pierces through Goku's shoulder, sending him into Vegeta, as they are sent into a mountain.

Goku launches from the mountain in Super Saiyan Blue Four Kaioken x20, as he appears in front of Omesus. He roars loudly, barraging him and sending him into the ground at full force. "HAAAAA!"

"Gck... You somehow managed to multiply your power," Omesus says. He groans from the force of the attacks.

Omesus powers up again, as his hair grows, transforming into the True Legendary Super Saiyan Three, multiplying his current power by eight times. He begins to push back Vegeta and Goku. They would be clashing with each other at speeds that almost rival an angel's, as winds would be sent throughout half the entire multiverse.

Omesus smirks, as he raises his True Super Saiyan power to the maximum. He launches a mega blast, hitting both Goku and Vegeta, launching them into another planet. "AGHHH!"

Goku and Vegeta vanish in front of Omesus, panting a little. Their auras begin to shrink, as they power down back into their base forms.

"Vegeta," Goku says, "Let's go further!"

Vegeta smirks, as he begins to roar, charging. Goku begins to stabilize his energy, rising it. Their energies begin to rise heavily, wind shooting everywhere.

Omesus raises an eyebrow. "You two managed to find power beyond that of Ultra Instinct?"

Goku and Vegeta finish transforming, as Vegeta is in Super Saiyan White, and Goku is in a form that Omesus has never seen before: Primal Instinct. He'd have mastered it during training.

Omesus's eyes widen a little. "What kind of Ki is this? It's very unique. What do you call this form?"

"It's Primal Instinct," Goku replies. "It's a form I'm not going to explain to you anytime soon. Let's begin our battle."

They launch at Omesus, as they punch him in the chest, causing Omesus to almost vomit blood. "GAHHH!" he roars in pain, as he is launched far away from Earth, far away from the Sun.

Space

The Saiyans appear behind Omesus, as they continue to barrage him, further damaging him. They then launch him through hundreds of planets, causing them to explode into millions of fragments each.

Omesus roars, as he launches ki blasts at them, but they simply deflect them. He flies toward them, his aura growing in size. "HRAHHH!"

"FINAL..." Vegeta begins. He charges his strongest attack, the Final Flash.

"KA... ME... HA... ME..." Goku continues. He yells loudly, a blue light coming from him.

"HAAAA!" They both launch the Final Kamehameha at Omesus, as it is just then deflected...? "Hehehe..."

Goku and Vegeta look at Omesus, as his hair is shining blue. "Not bad..."

"Interesting..." Omesus says. "I managed to combine God Ki with the True Super Saiyan form... I suppose I will call it the True Super Saiyan God..."

He launches at Goku and Vegeta, as they begin to clash, their powers equal with one another, as they continue to clash, occasionally teleporting throughout the Milky Way galaxy. Each clashed punch causes the multiverse to shake, as it is in danger from their powers.

Omesus roars, as he activates all of his power, knocking them both into different planets, causing them to explode as well. Just when he was going to launch his strongest blast and incinerate the both of them, he feels an intense blast on his back, sending him forward. "What the?!"

Omesus turns around and sees Beerus and Whis, who launched the blast with their combined power. Goku and Vegeta appear next to them, ready to take on Omesus.

Goku chuckles, and Omesus squints at him. "What do you find funny?"

"We're still not at full power," Goku replies. "Let's show you what we can do."

Whis's eyes widen. "Could it be...?"

Vegeta yells, glowing white fur appearing on his chest. He roars, entering Super Saiyan White Four. Space cracks around him, forcing Omesus to shield his eyes from the power. "What the?!"

Goku inhales while in Primal Instinct. "This could go very wrong, but we'll have to find out if it works or not!" His aura bursts, electricity shooting across the multiverse.

His already white hair glows even brighter, as his aura turns a more purple color. His power rises a lot higher than Vegeta's. He opens his eyes, as he is in Primal Instinct Stage Two.

He'd have combined two angelic forms from separate FanFictions. He'd have the power of Primal Instinct and Super Saiyan White. Vegeta launches forward first, roaring. He swings a punch, slamming it onto Omesus's face.

He is sent back, grunting. He roars, and he and Vegeta clash rapidly, shooting through the Solar System. Goku watches from below, the form a big strain on his body. "It's now or never!"

He roars, launching forward at blinding speeds. He brings back his fist and slams it onto Omesus's face, sending him flying. "UWAGHHH!"

He continues to knock Omesus around, being stronger than him now. He kicks him upward and launches a Kamehameha that sends him flying toward Vegeta, who launches a Galick Gun to send him back toward Goku.

Goku raises his hands and a glowing ring appears in the sky. Beerus, Vegeta, and Whis look up at the ring in shock and confusion.

"What kind of technique is that?" Whis asks.

Goku roars, as energy from throughout the universes goes into it. "OMNI-SPARK!" A MASSIVE beam shoots from it, slamming into Omesus. He coughs up blood, his eyes twitching. "I-Impossible!"

Omesus roars, bringing back his fist. "WHITE DRAGON!" he launches his ultimate attack, it heading for Goku fast.

Goku grunts and brings back his fist. "DRAGON... FIST!" He launches his attack, and it crashes through Omesus's attack. Goku would have fought a different version of Omesus in his reality, so he wouldn't think about sparing him.

He roars, and Omesus is consumed by the attack, vaporized. There is a flicker of light, and a massive explosion ensues. Whis vanishes next to an exhausted Goku, placing a hand on his shoulder. "I must say... You are much different from our Goku. Alas, not even I know how to get you back, so you will have to be here for a while."

They wouldn't have required Broly's help, so they don't think about bringing him with them. They head to Zateus's palace, and the fight begins. When he finds out Omesus is dead, he is enraged.

Zateus clenches his fists, a bright aura flaring up around him. "You bastards!" He roars, launching toward Daishinkan. He kicks him in the gut, sending him flying. "Agh!"

Vegeta enters Super Saiyan White Four, getting into a stance. He flickers, and he launches off toward Zateus, slamming a punch onto his face. "HAA!"

Zateus's head has barely moved. He squints at Vegeta and punches him so hard, his ribs break. He is sent flying through the palace floor, angering Goku. He roars, entering Primal Instinct Stage Two.

He launches beams at Zateus, which he blocks. "You're annoying, mortal!"

Goku smirks, and brings back his fist, launching up toward him. "Omni-Fist!" He slams a punch into Zateus's gut, knocking the wind out of him. "You simpleton!" He mauls Goku to the ground.

Goku lands onto his knees, panting. "Tch... This form is too straining on my body... I can barely maintain it."

"Goku-san," Daishinkan says, "you are beyond the level of an angel. I have a plan."

Goku nods. "Don't waste time telling me it. Just do it."

Daishinkan raises his staff, and all of his children are drawn toward him again. He fuses with them again, causing the multiverse to flash. "Son Goku, you're going to fuse with me."

The Grand Priest taps his staff on the floor, and he fuses with Goku. Electricity dances across the air, and Zateus laughs. "What difference is one mortal going to-"

Before he can even finish, he is already tossed far out of Daishinkan's palace. "AGHHHH!"

Daishinkan vanishes above him, slamming his staff onto him. "This strange power... Angelic Ki, was it? It's very unique. I must learn it myself." He raises his staff, and lightning shoots off into the heavens.

He brings down his staff and a giant lightning strike slams into Zateus, and his eyes go blank. He crashes onto the ground, unconscious.

Ozatus would have never happened due to Omesus dying to Goku. Daishinkan finishes Zateus off before they defuse. This means Goku would not get Ultra Instinct Stage Three yet.

Years pass, and Goku still trains Uub. Daishinkan offers to train Goku and Vegeta. (Partly because he is interested in how Angelic Ki works). This is where we are going to be leaving things for right now.

What do you think of this what-if so far? Normally, I do what-ifs in a single chapter, but this is gonna be a long one. Plus, I have to make more After Broly so that I can correctly portray this version of Goku here.

To Be Continued in Part 2
