A/N 1: I hated Jiren's backstory, So I decided to redo it. I like the idea of Jiren being from another Universe that got destroyed, and I'll try to tie it into some stuff discussed in Comforting the Weeping Angel.
The destruction of the fight between Toppo, Goku and Vegeta soon is revealed. Where previously there had been three large sections of the arena remaining, now, there was only one fully intact. One was in about a hundred smaller pieces, while the second one was in about 5 large pieces.
With both Zen-Oh's and Grand Priest, Present Zen-Oh said "Oooh, Jiren's on fire", while Future Zen-Oh added "He's on fire"
"So amazing" Present Zen-Oh said, while Future Zen-Oh added "So cool"
Back on the arena, Android 17 said "What unbelievable energy! What kind of monster is he?" Jiren the flared his outermost aura, and blew back Goku, Vegeta and Android 17,
"He was hidin' such power" Goku said.
Back in the stands, Krillin said: "Th-The force of his energy is reaching all the way here!"
"What unbelievable power Jiren has" Master Roshi added. Tien then said, "Can Goku and the others actually fight against that?"
Back on the arena, the calm Android 17 normally showed briefly slipped. Vegeta then smiled, and said "With all your friends gone, you finally got serious? A late mistake to make. If we beat you, the last opponent, we win!". Vegeta and Jiren then stare each other down, before Jiren said "Don't make me laugh. None of you can beat me as banged up as you three are" Goku and Vegeta then powered back up to max, Vegeta to Beyond Super Saiyan Blue and Goku back to Super Saiyan Blue Kaio-Ken x50.
"Cocky bastard" Vegeta said, before rushing at Jiren, with Goku and Android 17 close behind. Jiren, however, rushed behind them before any of them could move very far.
"What the?" Android 17 asked, shocked, before, each in turn, Android 17, Goku and Vegeta are casually kicked into three of the floating rocks at different parts of the arena by Jiren. All three of them leap back and fight Jiren. However, it becomes obvious very quickly that Android 17 can't keep up. Jiren doesn't even need to block Android 17's attacks, they're not damaging him, allowing Jiren to block everything that Goku and Vegeta are throwing at him.
"These guys. Impudent gnats!" Jiren said as he grabbed Android 17 and slammed Vegeta and Goku with him, before throwing Android 17 across the arena. Android 17 barely avoided soaring off the arena by countering his momentum with a constant Ki blast.
"That was close" Android 17 said. Goku got back to his feet and fired a series of Ki blasts at Jiren, but he easily avoided them. Vegeta attempted a Final Flash, but Jiren reflected it back at Vegeta with a glare. This, however, allowed Android 17 to get behind Jiren and strike him with an energy blast, causing a huge explosion that destroyed half of the remaining arena, and also disintegrated a large number of the surrounding rocks.
In the stands, both Krillin and Android 18 yelled "Android 17!", before Android 18 suddenly fell back.
"Android 18, are you alright?" Tien asked as Krillin ran over to her. Android 18 grabbed her head, but as soon as a Migraine hit, it had disappeared.
"What the hell was that all about?" Android 18 asked herself.
Whis, meanwhile, looked puzzlingly at what had just happened with Android 18.
"Are Android 17 and Android 18 twins?" Whis asked, to which Krillin confirmed.
"OK. If that's the case, I had better warn Android 17 about something" Whis said. He then yelled "Android 17, if you can hear me, be careful, you and Android 18 may be life linked"
But back on the stands, nobody heard, partially because they were on the opposite side of the arena to Whis, but partially because the dust blown up had obscured everything for the remaining fighters.
Android 17 pulled himself out of the wreckage and said "I guess getting caught in my own explosion was a bit too reckless" he fell to his hands and knees, breathing heavily, but when the smoke cleared, Jiren was still standing. However, there was a large hole in the back of his uniform, and he had several scratches on him.
In the stands, Khai said "Jiren's wounded"
Back on the arena, Jiren yelled "CURSE YOU!", to which Android 17 replied "The damaged look actually suits you"
"Bastard" Jiren said, and he charged at Android 17.
Android 17 shot many energy blasts at Jiren, but they just bounced off him, forcing Android 17 to leap over Jiren and re-join Goku and Vegeta.
"Are you OK Android 17?" Goku asked, to which Android 17 replied "Kinda"
"Hey, Android 17, we have a problem" Vegeta said, looking up at the stands. Android 17 looked up and saw Android 18 holding her head, the migraine had returned.
"What the? What's going on there?" Android 17 asked, puzzled by this development.
In the stands, Whis took the opportunity to call "Android 17, be careful, there's a chance that you and Android 18 may be life linked"
On the arena, Android 17 looked puzzlingly at Goku and Vegeta and asked, "What's a life link?" to which Goku replied "It's an ability where two being's life forces are linked together. So, if one dies, the other will die as well"
"Oh" Android 17 said. Goku then said "You really are impressive. Thanks to your attack, I know how to deal with Jiren" which surprised both Vegeta and Android 17.
"Looks like gettin' hit by an attack that big, unguarded, can hurt him" Goku said, to which Android 17 added "I see. If we can make an opening with coordinated attacks, and hit him with an even bigger attack"
"Yeah, we might just beat Jiren" Goku finished.
"Are you two done talking? If so I'd like to knock you three off now" Jiren said.
"First, Vegeta and I'll get Jiren's attention. At that moment" Goku said, to which Android 17 replied "Got it"
Everybody then powered up to the max, while Jiren powered up to 75% of his maximum power.
"Good, you're finished. Now to knock you three off and get my wish" Jiren said.
"Don't worry, we're going to pay you back for what you've done to us" Vegeta said, to which Goku added "Now it's our turn"
Android 17 fired an energy blast at Jiren, who stared it away. Goku and Vegeta then charged, and Jiren briefly blocked their attacks, but Goku managed to get a kick on Jiren. Goku and Vegeta then engage Jiren, and manage to land a few hits on him, but can't seem to make an opening. Android 17 tries to follow but struggles to keep up.
Goiku, Vegeta, and Jiren then reach the remains of the rest of the arena not already obliterated by the fighting so far, and leap from rock to rock, trying to land hits on each other. Goku and Vegeta seem to create an opening, but when Android 17 fires his blast, Jiren just said "That will only work once" and used his stare to deflect it around him, before slamming Android 17 into the ground with a devastating kick.
"What the?" Goku asked, while Vegeta also said "Impossible"
Goku and Vegeta then shoot ki blasts at Jiren, but they're easily stopped by counterblasts from Jiren.
"Vegeta, Android 17, let's all hit him at once" Goku suggested. He, Vegeta and Android 17 then headed for different angles, and all fired their strongest blasts. Jiren, however, just used a spinning version of his energy attacks to stop Goku's, Vegeta's and Android 17's blasts from reaching him.
"Pathetic" Jiren said, before firing his energy blast at everybody, completely overwhelming all three blasts. Even 100 Android Barriers weren't enough to stop Jiren's blast, and only bought Android 17 enough time to barely escape, while Goku and Vegeta cop direct hits, sending them slamming into the remaining piece of the arena. Also leaving only Android 17 standing, though barely.
In the stands, Krillin said, "Oh no! They're in big trouble" while Belmod said "This is the end, Jiren's absolute power will wipe out Universe 7", to which Beerus growled and said "This isn't over yet. There are less than 2 minutes remaining, and we're up 3 to 1" which shut Belmod up, briefly. Then he said, "Jiren, wipe all three of them out using your next attack!"
Back on the arena, Goku said "How could he beat our coordinated attack?" to which Jiren said "Time's up"
Android 17 was the first to recover. Jiren, noticing this, asked, "What can you do alone?"
"I haven't given up just yet. Universe 7 will survive"
Vegeta, seeing Android 17 stare down Jiren, said "He", while Goku said "No. 17"
Back in the stands, Belmod said "So You'll survive. And then what? You'll survive. And then what? What will you wish from the Super Dragon Balls?
Back on the arena, Android 17 said "I'm going to obtain the Super Dragon Balls, and fulfill the agreement Universe 7 made, to reverse the erasing of Universe 6's Angel, so Universe 6 can be brought back"
Back in the stands, Belmod said "A noble gesture"
Back on the arena, Android 17 asked "What about you, Jiren? Surely, nothing aside from the title of strongest interests you". After a few moments, Jiren spoke.
"Even I have a wish I want to be granted"
Back in the stands, Khai said "Jiren's wish?", while Belmod added "I see. Jiren, you still", and at this, Belmod went dark. Noticing this, Khai asked "Belmod?"
Finally, Belmod said "Let me tell you all. The reason for Jiren's obsession with strength"
Flashback Begins (Yes, I'm about to reduce the number of Universes destroyed by Zen-Oh tantrum from 6 to 5).
The scene then changes to a teenage Jiren, watching in horror as his Universe is swallowed up by a strange, dark cloud with a demonic face.
"NO! GET BACK!" Jiren yelled, firing his energy blasts at it. However, it didn't affect the shadow. Suddenly, the God of Destruction of the Universe arrives, along with Belmod.
"Zen-Oh's on his way, the only way this thing can be stopped from spreading, potentially to other Universes, is to destroy the one its currently in. Get Jiren out of here, he's our best hope. GO NOW!"
"Martoan" Belmod said. He then nodded, grabbed Jiren, and they fled. Suddenly, Zen-Oh appeared.
"Lord Zen-Oh" Martoan said, kneeling in worship. Zen-Oh looks around and sees the evil spirit rampaging towards them.
"What is it?" Zen-Oh asked, then added "He's annoying", to which Martoan replied "Right? Don't you think you should erase him? Plus our Angel's ignoring us, can he go too please?"
"You're right. A world like this, a world like this must disappear. Sorry Grand Priest, but your son failed in his duty. And as a result, Universe 15 must go" Zen-Oh said, and, within a second, Universe 15 was gone, leaving only Jiren, onto whom Belmod had slapped a Grand Priest protectorate badge onto, as the last person left in the Universe.
"I'll go and take you to Marcartia and Grand Priest, we'll get you transferred to Universe 11" Belmod said, while Jiren just screamed.
Flashback ends.
"Consumed by grief and PTSD form the loss of his Universe. That's when he realized trust was useless. He also realized that strength is justice. Strength is will bring companions. Winning would get him everything, maybe, Universe 11 could fill the hole in his heart left by Universe 15. That's why he's so attached. Emotions mean nothing there. Jiren had been fighting that thing for many years, and it drove his thirst for strength, which is what drew me to him, and why I saved him in the first place. His solitude also drew me to him"
Back on the arena, Android 17 said "I see. Your wish is to bring back at least some part of Universe 15. And here I was thinking you were just a fighting machine. You're a pretty human guy too" Android 17 said. Jiren then grunted, and said "That's enough out of you, Belmod" he then shot an energy blast at Android 17, knocking him well back.
"Trust, huh? So you were just using those guys to your own ends" Android 17 said.
In the stands, Belmod yelled "SILENCE!~ WHAT DO YOU KNOW OF JIREN?"
Back on the arena, Android 17 said "You live, obsessed with the past" Android 17 said as Jiren swung at him, which he barely avoided.
"Looks like I hit a nerve there" Android 17 said. Jiren the grabbed Android 17 and slammed him through ten rockfaces. Android 17 charged back, but his punch was easily blocked by Jiren.
"Do you think you can make things like there were if you win? That you can bury the past?" Android 17 asked as his shirt sleeve slowly disintegrated.
"Ridiculous" Jiren said. He grabbed Andorid 17, and slammed him across the ground, intending to throw or blast him off, but Goku, using Instant Transmission managed to grab Android 17 and teleport him away from the blast.
"That does it. Ultimate Energy Burst" Jiren said. He generated an enormous blast of energy and fired it at Goku, Vegeta and Android 17.
"Strength is absolute. Strength forgives all. Even the past Lament your weakness" Jiren said as the blast cannoned towards them.
In the stands, Krillin said "Goku! Vegeta! Android 17!", which Android 18 added "Android 17"
"Get up, Goku" Beerus said.
Back on the arena, Android 17 throws up another hundred barriers, trying to protect Vegeta and Goku.
"You, what are you doing?" Vegeta asked, shocked by what Android 17 was doing. Goku, also shocked, said, "At least save yourself".
Back in the stands, Android 18 said: "That's crazy Android 17!"
Back on the arena, Jiren pushes himself to 100% as he slowly pushes through Android 17's barriers.
Back in the stands, Android 18 said "You're not strong enough! Run, Android 17!"
Back on the arena, as more barriers are smashed, Android 17 said "Hey, Goku, Vegeta, I leave the rest to you two", before generating shields around both.
"Hopefully you got some rest. Sacrificing myself for others, I kind of like how human that is" Android 17 said.
Back in the stands, Krillin yelled "ANDROID 17, DON'T DO IT!", while Android 18 went further and yelled "ANDROID 17! WE'RE LIFE LINKED! IF YOU DO THIS, YOU'LL BE KILLING ME TOO!"
Back on the arena, though, Android 17 didn't hear them. He turned himself into a bomb, intending to destroy the blast, and himself along with it.
"Android 18, if we are life linked, and you die because of this, then I'm eternally sorry" Android 17 said.
As Android 17 started on his Barrier Explosion technique, the ground breaks apart completely. Goku grabs Vegeta, and attempts to use Instant Transmission, intending to get both onto the central pillar. However, that arm is grabbed by Jiren.
"I've used an energy-momentum move to keep the blast going, even though I'm not controlling it" Jiren said. Goku, in desperation, kicked Vegeta onto the central pillar, allowing Vegeta to narrowly avoid the blast. Jiren then kicked Goku off the arena.
With both Zen-Oh's and Grand Priest, Grand Priest said "Universe 7's Goku has dropped out" and Zen-Oh tapped the godPad, signaling Goku's loss.
Goku returned to the stands, said "Sorry I lost Beerus", to which Beerus said "You had better hope Vegeta wins, or I'm making sure you don't come back", which horrified Goku. He then turned to face Whis but got no more than "Is it OK if I" when, suddenly, Android 18 collapsed as Jiren was consumed by the Barrier Explosion technique Android 17 was using.
'ANDROID 18!" Krillin yelled as she was grabbed by Tien and Goku, Krillin racing over as she began to fade like Kami did as he and Piccolo died in the Saiyan Saga.
"So, Android 17 and I, were life linked after all" Android 18 said, breathing heavily. She turned to face Krillin, kissed him, and said, "Take good care of Marron, and of Android 17's family, until we can be brought back with the Dragon Balls" Android 18 said.
"I will" Krillin said, on the verge of breaking down crying. Android 18 then said one final goodbye, then vanished, leaving an inconsolable Krillin behind.
Back on the arena, Jiren was found lying, seemingly unconscious, on the only remaining rock from the Tournament Arena. Vegeta, meanwhile, was lying on the time pillar, also barely conscious.
"Whis, was Android 17, and Android 18, life, linked?" Vegeta asked, to which Whis nodded.
"Dammit! Thanks, Android 17, I think, he did enough, I can win, from here" Vegeta said.
Back on the arena, Old Kai said "Not only did he put a barrier, but he self-destructed to try to erase Jiren's attack"
"Jiren, you idiot. Why did you knock Goku off? Didn't you realize just how close you were to Android 17?" Belmod asked, shocked.
With both Zen-Oh's and Grand Priest, Grand Priest said "We can assume that Android 17 destroyed himself with a self-destruct. Therefore Universe 11's Jiren shall receive no penalties. In addition, we can also assume that Android 18 died due to the life link, Therefore Universe 11's Jiren will receive no penalties for that either"
Back on the arena, Jiren slowly pulled himself up. The blast had taken its toll, the side that had grabbed Goku was missing the top half of his suit, and he was heavily battle scarred.
"That wasn't a wise move, but I did knock off Goku. Now, only Vegeta left" Jiren said. At the same time, Vegeta pulled himself up, and both Jiren and Vegeta faced each other.
"You're still standing" Jiren said. Vegeta replied, "Jiren, I'm more than enough to knock you off!"
The narrator then said "Android 17's power saved Vegeta from peril. However, Goku was knocked off by Jiren in the process. This, however, cost Jiren heavily. Vegeta musters up the spirit and stamina to go against Jiren in a final showdown. How will he face Jiren's overwhelming power, on the time stand? Just one minute remains in the Tournament of Power".
A/N: Yes, the life link between Android 17 and Android 18 throws up a ton of questions. I'll try to answer what questions you do have.
