What If Abysus was Spared? Creating a scenario for this would be very tricky to do, but I have to make it happen, even if it is slightly out of character.
In this scenario, the combined blast between Daishinkan, the angels, the gods, and the fighters was slightly weaker than in the original. It would be enough to knock Abysus unconscious, but not vaporize him. He, of course, didn't die in the original anyway, but what if he was never vaporized and forced to retreat?
Jiren appears at the side of Goku, adding some of his power into the blast, making it bigger. The blast would take on a red tint, as it is now full of Jiren's raw energy.
"I-IT'S NOT ENOUGH!" Vegeta yells. "WE'LL GET KILLED AT THIS RATE! KAKAROT, YOU WILL NEED TO USE THE SPIRIT BO-"
Then... Daishinkan appears between Goku and Vegeta, placing his hands on the blast, increasing its magnitude and size by thousands of times. "You are not alone, Son Goku-san, Vegeta-san, and Jiren-san! HAA!"
"NNNGH!" Abysus holds out both of his hands, struggling against the blast. He does his best to push against the blast, but it is starting to overpower him.
"MORE POWER!" Goku yells, as he, Daishinkan, Vegeta, and Jiren yell, adding more power to the blast.
Abysus groans, struggling some more. "I AM... LORD... ABYSUS! I WILL NOT... FAIL! YOU ALL... WILL NOT WIN!"
He pushes against the blast, beginning to slowly walk through it, blocking it. "I HAVE WON, YOU FOOLS! THIS WILL NOT WORK!"
"EVERYONE! FULL POWER! KAIOKEN TIMES 40!" Jiren and Daishinkan go into full power, and their blast overpowers Abysus. "HAAAAAAAAAAAAAAA!"
"NNNGH! NOOOOO! I.. WILL NOT FAIL...! AGHHHHHHH!" The blast finishes after a while, and there would be a bright light.
When the light fades, Abysus falls back toward the arena, crashing into it. He'd be unconscious, and everybody would be exhausted.
Daishinkan vanishes next to Abysus and brings up his staff. "It's now or never. I have to destroy Abysus before he can come back stronger."
Goku lands next to Daishinkan, looking up at him. "Wait, let him live."
Daishinkan glances up at him, stunned on how insane this request is. "Son Goku, that is unacceptable. You know how he has nearly destroyed us."
"Let him live to fight another day," Goku insists. "He's incredibly strong. If he can become an ally, he'd be a great asset."
Vegeta goes down to him, grabbing him by the shirt, and slamming him into the ground, causing him to cough up spit. "YOU ARE FOOLISH! BEYOND FOOLISH! HE NEARLY KILLED US ALL!"
"Goku-san," Whis says, "do you realize what you are asking? Abysus is an enemy of the gods. You cannot simply change him. He's not a mortal."
Goku and Daishinkan lock eyes for a moment and then seem to come into an agreement. Daishinkan sighs, as he taps his staff on Abysus, a forcefield surrounding him. "I suppose I do owe Son Goku a debt for saving us... However, Abysus will be locked up with very tight security."
Abysus would be locked up and under tight security. Daishinkan would have gotten some gods to monitor Abysus's actions and inform him immediately if he threatens them.
Abysus grunts, as he wakes up, looking around in confusion. "Wha... Where the hell am I?!" He'd see he is in glowing chains and tries to break out of them, causing dust to fall from the ceiling.
The gods back away, ready to call for Daishinkan. Luckily, Abysus would not be able to break out of the chains. Eventually, he stops, growling. He looks up at the gods, giving them a death stare. "Where... the hell... AM I?!"
One of the angels steps forward, pointing their staff at Abysus with no fear in their eyes. "You have been spared due to a request from Son Goku. You will be locked up here for the time being."
Abysus would take a moment to process this, before tugging on the chains even harder than before. "A mortal...? A MORTAL TAKES PITY ON ME?! I'D RATHER DIE!"
Even with full force, the chains do not break. Abysus grunts, feeling humiliated. "Gch... Once my father returns, you will perish, and he will set me FREE!"
The angel slams his staff on the ground, sending a glow that travels up Abysus's body and makes him feel pain. "Abysus, you should count yourself lucky. You would have died at the hands of Daishinkan if it weren't for the mortals. Be grateful to them."
Abysus hesitates for a moment, then yells back at him. "Why... WHY SHOULD I... Be... grateful?!" His voice weakens slightly, but then his facial expression toughens again. "Damn you... You think you gods are so above everybody else... Once my brother Arysus, the strongest out of us, comes back, you will all perish!"
Abysus would be in complete shock with how the gods actually spared him. He came to the battlefield, expecting to kill as many gods as he could to make it simpler for Zateus, Omesus, and Arysus to take over the multiverse. He thought he'd eventually die by Zeno.
Instead, he'd be locked up and would feel humiliated, and his hate for the gods would slightly dim, but he'd always deny to himself that he'd soften up to the gods.
Due to Abysus never being vaporized and reduced to a small fraction of himself, the second Abysus arc would have never happened. Goku and Vegeta would still get the angelic boosts from Whis. (I made the mistake of not giving them the boosts in "What if Abysus never showed up" what-if because I realized Whis would give them the boosts regardless.)
Vegeta wouldn't get Super Saiyan White yet, but Goku would be taught to do Ultra Instinct Stage Two and do the ritual that he did before fighting Abysus. Whis would have promised Vegeta that he would teach him the White Divine Ki sooner or later.
They continue to train until Broly arrives. By this time, Abysus would have changed a little, but still not trust the gods. He'd be locked up, but he'd be allowed to leave his cell for a walk with some guards.
In this timeline, Whis would have trained Goku some more to use Ultra Instinct Stage Two due to having more time to do so before the Broly arc. This means Goku would be able to activate it at will earlier than before.
Vegeta still wouldn't achieve Super Saiyan White, but he'd be on the brink of doing so. Angered at the gods for keeping Abysus locked up, Zateus would secretly go to Broly and give him a boost before the arc.
Broly arrives and the fight plays out a little differently. Broly would be even tougher and would be able to beat Goku, even in his Ultra Instinct Stage Two state. He'd mercilessly beat on him, knocking him unconscious.
Vegeta would get very angry that Goku has passed him very far. Eventually, he snaps. He enters Super Saiyan White, but this time, he'd be even stronger. He'd have a rage boost similar to when Abysus destroyed Earth in the original.
He and Broly would be equal throughout the fight, but Vegeta eventually comes out on top. Due to Goku being unconscious, he wouldn't convince him to spare Broly and Paragus. Vegeta finishes the two of them off, before taking Goku back at Capsule Corp.
After Broly, the Omesus arc plays out mostly the same, except Broly wouldn't be around, so Gogeta would have to appear earlier on.
When the Zateus arc comes around, things would end up being a lot different.
The Grand Priest appears behind Lord Zateus. "You have made a mistake coming back, Zateus." An invisible force from the Grand Priest knocks Zateus toward the gang at high speeds.
Goku goes Ultra Instinct, as he throws a kick at Zateus knocking him back. Vegeta goes Super Saiyan Blue Evolution, as he throws a punch, knocking Zateus toward the floor. Broly goes into his Legendary Super Saiyan form, as he launches a blast from his mouth, knocking him toward Beerus, who activates his full power and kicks Zateus toward Whis, who swings his staff at Zateus, launching him toward Omesus, who goes into Super Saiyan White, knocking him to the ground, causing a massive crater in the floor.
Later on, when the Grand Priest Angel Fusion gets defeated, Goku suggests something shocking.
"Release Abysus!" Goku pleads, and everyone looks at him, stunned. Goku grunts, clenching his teeth. "Release Abysus, and he'll help us!"
Even Omesus and Zateus would be silent, but Zateus bursts out laughing. "HAH! You expect my son to listen to the likes of you? Do you think you gods can take my son? But of course, release him. We could use a new helper..."
Omesus and Zateus do not fuse yet, since they believe they could also include Abysus in the fusion and make them even stronger. The Grand Priest realizes he has no choice and releases Abysus.
Abysus teleports here, cracking his knuckles and neck. He looks at the gods, then at his father and Omesus. "It has been a while, father..."
"Come forward, son," Zateus says, raising his hand. "Come join us, and we will join together to destroy the gods."
There are two ways this could play out. One, Abysus accepts and fuses with the two, creating Abzasus, who is stronger than Ozatus, but weaker than Abzarus. In this case, none of them would be able to win. Even if Goku gets Ultra Instinct Stage Three, he'd still lose and perish to Abzasus. Later on, he'd be erased by an Order, Oblivion would succeed and then be killed by Tier twos and above, Akuma would succeed, blah blah blah.
Let's stick with scenario two for this what-if.
Abysus stops then turns toward the gods. "You are the only ones who have treated me with even the smallest bit of respect. My father only used me." He walks toward the stunned gods.
Zateus gets a look of rage on his face and raises his hand, charging a blast. "I see your time with the gods has softened you up, son. It's time for a little discipline!" He launches a giant blast toward his son.
Abysus snaps toward him, as he roars, punching the blast away. He'd be close to Zateus, but being SLIGHTLY weaker. The blast is sent out of the palace, exploding in the sky. "Never dare call me your son anymore, Zateus... I have realized the truth, and that is you are CORRUPT!"
Daishinkan glances at Goku, his mouth slightly curling up in a smile. Goku would get the message, and Daishinkan would agree that sparing Abysus was a good call.
Zateus crackles with energy, electricity sparking around him. "You're a failure, Abysus!" He tosses an earring to Omesus, and the two fuses into Ozatus, shattering the palace and shaking the multiverse.
Even Abysus would have no chance against the likes of Ozatus. He'd be quickly knocked around, and events play out similar up until Vegeta is about to die.
However, Daishinkan would have another idea up his sleeve.
He pulls out Potara earrings and raises one toward Abysus, his face deadly serious. "Abysus, I know we are enemies, but right now, we only have one option. We must fuse into one."
The two have a brief argument, but Abysus eventually agrees. He places on the potara earring, and the two gods fuse into one being: Abyshinkan.
The level of power that Abyshinkan has would manage to overpower Ozatus and destroy him. Due to Vegeta never dying, Goku wouldn't unlock Ultra Instinct Stage Three yet.
After defusing, Abysus would start being accepted by the gods as one of their own and release him from his prison. He'd now be free to roam wherever he desires.
Due to Abysus basically saving them instead of Goku, Daishinkan would offer Abysus a place in the Angelic Chamber. However, Abysus requests that Goku AND Vegeta follow him.
Uub wouldn't have much of a role due to not being invited to the Angelic Chamber this time. Daishinkan would train Abysus, Goku, and Vegeta. Due to the two Saiyans sparring with Abysus, they would become even STRONGER than in the original.
Arysus would eventually arrive, and try and destroy Earth. However, Goku, Abysus, and Vegeta arrive.
Arysus would be baffled at why Abysus would be on their side, and how he is so unbelievably powerful. He walks up to Abysus, grabbing him by the collar. "What happened to you, Abysus?! YOU FOOL! YOU TRAITOR!"
Abysus's face tightens, as he waves his hand, sending Arysus crashing through a mountain. "I'm past working with any of your kind. Give it up. You're outnumbered, and you're weaker than us."
After seeing how powerful they were, Arysus wouldn't be as cocky as before. Rather than summon old enemies from earlier in the series, he would choose to use all of his summoning power on Zateus and Omesus. He'd give them a bigger boost than before.
All of the Z-Fighters arrive, and they don't have minor opponents to deal with, unlike the original. They would all gather in front of Arysus, Zateus, and Omesus.
The three evil gods take on all of the fighters, but they are easily outmatched. They are forced to fuse much earlier than in the original. They would be missing a member, but the power loss would be compensated with the boost that was given to Zateus and Omesus. One warrior is formed: Arzatus
Eventually, Arzatus is forced to use 'The End' blast, but the big three power up to their full forms. Abysus and Goku enter Ultra Instinct Stage Three, and Vegeta enters Super Saiyan X, which is 20x Ultra Instinct Stage Three.
Vegeta would have gotten Super Saiyan X a lot earlier due to being invited to the Angelic Chamber. Together, they all overpower and destroy Arzatus, completely incinerating them.
Since Daishinkan never had to sacrifice himself to help defeat Arzatus, he'd remain the Grand Priest, and Goku would remain a mortal. He eventually gets a call on his staff from Adia, who asks to speak to Goku, Vegeta, and Abysus.
In the original, Adia would have been interested due to the high energy coming from their multiverse. She would want to speak to the strongest out of them, and that would of course be Goku, Vegeta, and Abysus.
Things play out mostly the same. They are introduced to the Omniverse, and they spar with Adia and easily win. They then spar with an Order and lose individually. However, Goku and Vegeta fuse into Gogeta.
The two unlock Ultra Instinct Stage Four, shocking Abysus and the Order. Gogeta actually DEFEATS the Order, even if it goes all out. The Order would be very impressed, and would actually convince Ahton to allow him to train them.
The only reason Ahton would have given them training was due to Gogito's power in the original, so he agrees to let them do it.
Due to the three of them being insanely strong, they would have no desire to form a team. The Order would train the three for a very long time and they would come out insanely powerful.
They'd go down the Path to Chaos and meet Omesus, Zateus, and Arysus. Abysus would get mad at them and beat them down. This means they would never get the black mark. He'd eventually let them go, though. They go to the Rogues and enter Ultra Instinct Stage Four to defeat them easily. Due to Adia not coming with them, she'd never be erased.
Goku, Vegeta, and Abysus would see their multiverse pod arrive and they'd find out that Omesus, Zateus, and Arysus had destroyed their multiverse and declared war on the Omniverse and about the return of Chaos.
Angered, the three of them train for a month until the event, making them even stronger than before. Eventually, the war begins.
Rather than Abysus creating soldiers for the first round in the original, Arysus would summon all of Goku's old enemies to fight him at once, and they would be boosted far, FAR more than in the Arysus arc in the original.
Still, Goku, Vegeta, and Abysus would easily pick them off. Next would be Omesus, Zateus, and Arysus. The three of them would have trained harder due to being beaten down by Abysus.
The three enemies would give Goku, Vegeta, and Abysus a run for their money, but they transform and are able to take them down quickly. After that, the multiverse portals open up and out come reinforcements to help the three of them.
The only difference is that Goku's old enemies wouldn't be with the reinforcements, due to just being summoned by Arysus, and never be converted to the good side. Still, there would be a lot of reinforcements.
Right before Arysus dies, he releases Chaos and all hell breaks loose. He'd kill Vados, angering the three fighters. Goku, Vegeta, and Abysus transform into Ultra Instinct Stage Four and just begin WHALING on Chaos.
The three of them would be tossing Chaos around like a ragdoll, beating down on him. This means that Jiren and Future Trunks do not die. Chaos becomes enraged, and he eats the Omni orb.
He transforms into Oblivion and the three of them begin fighting. Unfortunately, Oblivion would be able to easily overpower them with how powerful he truly is. Goku creates a massive Genki-dama, but even that is not enough.
Eventually, he gets enraged and slices his sword through Vegeta's neck, killing him instantly. Goku explodes with rage, his body flickering for a moment. He gathers energy at his fist and slams it into Oblivion, sending him flying back.
He would have temporarily accessed just a tiny bit of the power of Omni Evolution from his rage, but he wouldn't transform, but just use it in a singular punch.
Oblivion would roar and launch a massive blast that destroys all of them, but then it is reversed and Ahton arrives, along with Vegeta, who has Ahton's blessing.
Goku and Abysus also gain the blessing and Ahton's guards attack Oblivion but eventually lose against him. Goku, Vegeta, and Abysus begin to combat Oblivion, eventually being pushed to Ultra Instinct Stage Four. They eventually lose against Oblivion as well.
Ahton would be forced to step in and the battle would play out just as in the original, which Ahton eventually losing to Oblivion. All would seem hopeless, or would it?
Goku would have gotten close to obtaining Omni Evolution with his rage boost from losing Vegeta before the blessing. Now with the blessing, he is able to achieve it with a lot of effort.
His body breaks beyond his limits, and it is no longer limiting his power. He would attack Oblivion and be able to put up a very good fight against him. However, he wouldn't quite be as strong as Gogito in the original.
Daishinkan brings out the same Original Potara earrings Goku and Vegeta used against Abzarus in the original story. They put it on, and the ultimate Omni Evolution Vegito is born.
At this point, it'd be no contest. Vegito tosses Oblivion around like a ragdoll. Eventually, he launches his ultimate Omni Spirit Bomb Final Galickamehameha, but it would be a lot more powerful this time.
No help from other Tier Zeroes would be necessary. Oblivion would be erased, and the day would be saved.
Now, it is time for War Between Worlds. The early part of the story would play out exactly the same as before, with other anime characters fighting the Voidic Beings.
Things would remain normal up until Zalama arrives to train Goku, Vegeta, and Abysus up in Heaven. They would be a lot stronger than in the original story, of course.
Zalama would be impressed when he sees that all three of them have already obtained Omni Evolution through training with each other, (especially Goku). He trains them in his realm and they become UNBELIEVABLY stronger.
Beerus would never have become the Grand Priest, and Daishinkan isn't as careless as him, so he never offers to train Capper, Raddis, or the other anime characters, making them completely irrelevant.
Tiias arrives at the multiverse and completely destroys Daishinkan, killing him, along with the entire multiverse. Because of this, Tiias is able to escape well before Ahton and his Orders arrive.
Adia is forced to face the Voidic Beings alone at the Central and loses before Goku, Vegeta, and Abysus step in. The creatures would prove to be no problem for them.
A while later, Tiias arrives and they begin their fight. With them being even stronger than in the original, they are able to handle Tiias a lot longer. They would still be Tier Three, but closer to a Tier Four.
Eventually, they still lose. Zalama steps in and the fight plays out the same. He loses as well, and Goku and Vegeta are forced to use Arhenahin: Fusion.
Gogito would be immensely powerful. However, just as in the original, Tiias comes out on top. Even worse, with Gogito's level of power, he'd be a Tier Seven.
Reinforcements eventually arrive from many Omniverses, and the fight plays out the same until Arhenahin arrives. This time, his Tier Sevens and Tiias are a lot closer in power, due to him absorbing a stronger Gogito.
The Tier Sevens put up a good fight, but Tiias would defeat them pretty quickly. He attacks Arhenahin, and of course, the fight plays out the same. Everything plays out the same, from him fusing into God, to Akuma appearing.
When God does lose, he would have given Goku, Vegeta, and Abysus a huge boost. They try something they have never tried before: Triple Arhenahin Fusion.
The three fuse into one mega warrior: Abygito
Abygito would be far stronger than even God. He'd be able to toss Akuma around. He'd be closer to the level of Goku's Voidic Form in the original.
He creates the Ultimate Spirit Bomb that incinerates Akuma completely. Due to God not becoming conscious in time, he isn't able to tell them to seal him rather than kill him.
This means Akuma has reformed in the void somewhere away from the Metempiric Space. Eventually, he would probably return, but that would not be for a VERY long time. Goku, Vegeta, and Abysus would continue to train for eternity, preparing for the next threats.
THE END
I hope you enjoyed this what-if! I decided to stop doing this bold text because I noticed how much it can hurt your eyes. I'll probably do just italics instead.
This took hours to do. The butterfly effect really is big!
