Chapter 3- New allies

Earth-7

A portal opened as the Waverider flew out, and then docked onto the ground too.

It was near what looked like a cabin, the Healen Lodge. Lyla had brought them here on purpose, as it'd make things easier.

They walked out of the timeship, with Lyla and Oliver in the lead.

"So, this is where the ex-Shinra people live?" Barry inquired just to be sure.

"Yes, and even though Shinra is gone, they have their resources, and are now allies with Cloud's group, in spite of previous grievances", Lyla told them all as the door opened and out walked Reno and Rude.

"Whoa, whoa, whoa, its like we got a whole rabble here, yo", Reno said to his partner while holding his Electro-Mag rod in his left hand.

"What are your intentions?" Rude simply demanded as Tseng and Elena walked out too, pointing guns.

Lyla gave a nod to Barry and he ran, taking both of their guns from them and throwing them down, surprising the group.

"Whoa, does this guy run with lightning behind him?" Reno wondered, then looked at Barry up and down. "I do that too, yo."

"We are here to meet Rufus Shinra", Lyla immediately got down to business.

"And why do you all want to meet him?" Tseng asked, looking at the big and strange group.

"Its about Sephiroth", Oliver finally revealed, noting the shock on all 4 of their faces at the mention of his name. "Yes, that same Sephiroth."

Tseng shared a look with the other three, then gave a nod. Elena gestured to the door. "In that case, come in here."


A while later, the entire group was in, speaking to Rufus Shinra, who was quite the mysterious man. Oliver was reminded of Waller, though Rufus was nicer than her.

Sure he had his share of sins, but he was repentant of those.

"Sephiroth, I had a feeling a person like that could never be put down permanently", Rufus said grimly, holding up his gun as he paced around. "Really good son, isn't he?"

"Well, it's a mess then boss, we got this Multiverse thingy with so many other Universes, which is mind-blowing, and now Sephiroth is back, eh?" Reno wondered and groaned. "Its just messed up, yo."

"I am sure our allies would be of help in this scenario", Tseng said firmly, knowing they were the only ones who could defeat Sephiroth, having done it last time.

"Yes, that is true", Rufus nodded, and turned to Reno. "Reno, call Cloud, have him bring the whole group."

"On it boss, yo", Reno walked off to do as asked.

"Sephiroth's power has grown though", Barry pointed out to no one in particular. "Are we sure Cloud and the rest can stop him this time?"

"Well, it did seem impossible for them before too", Sara reminded Barry.

"I know something that will help Cloud", Lyla assured all of them. "Just let him and the rest come first."

"Whatever it is, let's hope it works, don't want Sephiroth to bring about the darkness again, do we?" Rufus asked no one in particular in a rhetorical tone.


A while later, the door opened and Cloud appeared. Ray commented without thinking. "He's shorter than I thought our savior would be."

Suddenly, Cloud was next to him, holding the massive Fusion Sword at his throat with a smirk. "You were saying?"

"Sorry, it was a joke", Ray assured as Cloud lowered it.

Oliver looked Cloud up and down. While not exactly tall, he was very well-built, and he and the rest had seen his battles with Sephiroth. Hopefully, he could save them.

"The swords here are so big", Mia commented, looking at the size of Cloud's sword.

Cloud shrugged as Sara asked naughtily. "Compensation?"

The blonde warrior groaned as Tifa now stepped in. "More like representation."

The girls all had funny faces at that, while Vincent, Yuffie, Barret, Cid and Nanaki with Cait Sith on top of him walked in. Denzel and Marlene were being babysat by another worker at Tifa's bar.

"So you are the lot from this other Universe, eh?" Barret asked as he took in the group of heroes.

"Other Universe, sounds like bullshit", Cid shrugged.

"Well, its not", Kara told him. "I was just as shocked as you all are now."

"I think we're more shocked", Yuffie said, then looked at Rufus. "So, got any plan?'

"Yeah, Sephiroth's back, and we're supposed to fight him", Cloud muttered, shaking a little, as Sephiroth always had the effect of trauma on him. Tifa held his hand for support, Cloud squeezing back gratefully.

"I believe with the power he has now gained, we may not be enough to really stop him", Vincent gave his verdict to them.

"Doesn't me don't have to try", Clark tried to raise their hopes.

"That optimism is gonna kill someone here, yo", Reno joked as Clark gave him a look but he didn't care.

"He could come here anytime, considering his power", Rude brought them to the matter-at-hand.

"What do we do?" Cait Sith wondered.

"Is there any way we can reduce his power?" Nanaki inquired, the heroes all looking at him strangely, since talking animals even they'd never seen. "What?"

"I'm done, man, I'm done", Diggle said and backed off, the rest all chuckling at him.

"Ignore them", Lyla said, then spoke to all of them. "The Lifestream is much bigger than any of you realize."

"By how much?" Tseng inquired.

"The Lifestream is in truth the combination of the elemental forces of the Universe- the Green, the Red, the Clear. It is connected to the life of the Multiverse", Lyla explained to them all, even Rufus surprised for once at this new knowledge. "And Sephiroth managed to get his power from the corrupted portions of it."

"Are you trying to say someone can get the power of the uncorrupted part then?" Rufus asked her and got a nod. "And I think I know who that'd be", Rufus turned to look at Cloud, as did the rest of them.

"Huh?" Cloud realized, sharing looks with all of them. "Guess it has to be me then."

"Where will we get it though?" Tifa then asked.

"Think its obvious where we have to go", Rufus smirked, Cloud's eyes widening in realization.

"The Northern Cave."


Soon after, all of them had been brought to the Northern Cave via a portal from Lyla, right near the Planet's core, where the final battle against Sephiroth had been waged years ago.

"So, he's just supposed to jump in? Wouldn't that kill him?" Yuffie asked, the concern in her voice clear.

"It won't", Lyla assured, looking at Cloud. "Someone who cares about you is in there."

Cloud nodded, knowing who was being referred to, as Tifa gave him a look. "Good luck, Cloud."

"I'll be back", Cloud assured, sharing a kiss on the lips with her before sharing a look with the rest of them.

"If you don't return, I'll kick your ass", Barret joked.

"Yeah, and I'll join him", Yuffie added.

"We know only you can get your ass out of such situations", Cid caused them all to chuckle.

"You will gain the power, Cloud", Nanaki agreed.

"Just come quick", Cait Sith said.

"Fly", Vincent simply urged.

"Cloud", Cloud turned to look at Oliver. "We're counting on you."

Cloud looked down, then back at Oliver. "I won't disappoint."

With that, he took a deep breath and jumped, taking a leap of faith.

Rufus watched with a neutral gaze. "You better not."


Cloud found himself in what looked like Aerith's church. "Where am I?"

"This is the Lifestream, Cloud."

Cloud turned to see Aerith walking to him with a smile, and both embraced. "Aerith, its so good to see you."

"Its good to see you too Cloud, though I wish the circumstances were better", Aerith replied as they kissed each other's cheeks.

"Yeah, Sephiroth, he never does stop coming", Cloud sighed with clutched fists, Aerith walking off while Cloud followed her.

"You're better than him though", Aerith assured Cloud. "You have triumphed over him 3 times now."

"And you believe this time will be the same?" Cloud asked her.

"Like your new friend Lyla told you, the Lifestream is energy that flows throughout the whole Multiverse, connecting to the Green, the Red, the Clear, basically all life, its powered by all living things, not just humans", Aerith explained to him. "Sephiroth never gained the vastness of the Lifestream's true power because he was not welcomed to it", she turned to Cloud with a smile, "but you are."

At that moment, she stepped aside and Cloud's eyes widened on seeing Zack standing there.

"Hey Spikey, how you doing?" Zack asked.


In the Northern Cave, the others were waiting when Lyla sensed something and her eyes widened.

"What is it, Lyla?" Sara asked immediately.

"He's…..here!" Lyla gasped, horrifying all of them.

"I think he's coming this way too", Clark said as next moment, Sephiroth hovered in the air above them all.

One-Winged Angel plays

"Sephiroth", Rufus snarled, his gun out.

"I wondered where you all were, yet, it seems your party is incomplete. Where is Cloud?" As Sephiroth finished asking, a black wing sprouted from his right shoulder.

"If you're so powerful, why don't you think about it yourself?" Mia taunted him.

"Yeah, you think you and him are connected, don't ya fucker?" Cid asked too as Sephiroth smirked.

"So smug", he shrugged, seeing all were prepared to fight. "Come and try."

Shadow Demons in the form of four-legged creatures appeared, roaring at them as they charged.

"Take them out!" Oliver ordered, firing an arrow as he managed to shoot one down, with Mia, Roy, Thea and Sara taking down one each.

Barry sped around, building up lightning and hitting one hard enough to take it out, as Clark punched one away and Kara did a thunderclap, sending one more off.

Lyla used her powers to reduce two of them to nothingness, as Diggle fired his gun, and Ray flew around in his rebuilt suit, firing beams too.

Reno ran, lightning coming off of him as he leapt and struck one with his Electro-Mag rod, taking it down. "There ya go fodder, yo."

Rude dodged the strike of one before kicking it, while Tseng and Elena shot them down too, and Barret shot many of them with his gun-arm.

Rufus was expertly dodging and one-shotting any ones coming at him with his gun. One wouldn't expect Shinra's former Vice-President to be this skilled but the man had fought even Cloud once alongside Darkstar, so he was full of surprises. At one point, he threw up 2 coins, and fired at those, causing lasers to be shot out as they killed 2 of the creatures.

Tifa managed to kick one away, then leapt and threw one down as Yuffie killed 3 of them with her thrown Shuriken, Cid battling two on his own as Nanaki ripped one apart, Cait Sith on top of him.

Vincent held up the best, taking down a lot of them on his own. Ray then tried to fire at Sephiroth but his suit was cut up again as he fell down, Barry catching him in time. "Thanks."

"No problem."

Clark roared and fired his Heat Vision, Sephiroth blocking it, then hitting him with lightning as he groaned, falling to his knees.

Kara tried to blow him away but he wasn't affected and closing his fist, thrust it outwards while opening it, Kara being sent back and feeling her chest getting a deep cut as she too went down on her knees, weakened.

Sephiroth pointed his sword at Tifa who jumped back. "Cloud is now in a place you can't reach."

"Is that right?" Sephiroth asked mockingly as he tried to slice at Tifa who dodged, then jumped at him with a punch that he dodged effortlessly as she reached his other side.

Tifa charged again, trying to punch or kick, using all her skills, but Sephiroth easily dodged before a punch from him sent her sliding back.

He tried to strike with his sword but she dodged his strikes, though unlike him, she was putting effort into dodging.

Vincent then transformed into Chaos Vincent before firing at Sephiroth, who blocked but this shot managed to send him back a little.

He then swung at Chaos Vincent who flipped up in the air and got behind him, firing again but Sephiroth dodged in time.

Both flew at each other, clashing too fast for the eye to see. They clashed again, then jumped back, ready to fight more.

Chaos Vincent dodged a strike from Sephiroth and shot him, sending him back, before Sephiroth dodged his next shot and flew at him, sending him down. Rufus once more threw up two coins and shot at them, sending lasers at Sephiroth, but he managed to send it away telekinetically.

"You are nothing", he sneered at the former President of Shinra as he charged down towards Rufus, about to stab him.

CLANG!

All fighting stopped for a bit, as everyone looked at the newcomer, and all of them recognized his face, the heroes because they'd seen him in Lyla's projection.

But no one's reaction was as strong as Sephiroth's.

"Genesis", Sephiroth growled in anger, his Masamune now in a draw against the Rapier of Genesis Rhapsodos, who'd saved Rufus Shinra from his demise by flying in the way and blocking Sephiroth.

"Hello, old friend", Genesis smirked, he and Sephiroth circling each other.

"Figured you were dead", Sephiroth commented, the other heroes having the same feelings, considering what they knew.

"No, the Goddess sent me back to actually fulfill my duty- as SOLDIER!" Genesis declared, Sephiroth tilting his head with a smirk of his own.

"Come and try, old friend", Sephiroth shrugged as he and Genesis clashed blades, sending out shockwaves, with both of them now clashing against each other in the air, with stuff breaking apart.

Genesis fired some magic fireballs like in their duel all those years ago, though Sephiroth managed to block all, then charged Genesis, about to stab him, but Genesis blocked in time, though he was punched away.

Chaos Vincent fired at him again, sending him back, and both he and Genesis charged Sephiroth, with Sephiroth blocking both their blows while they did their best to dodge his before Genesis did an 'Apocalypse', casting a red magic sigil under Sephiroth before gathering energy in his hand and casting lightning all over Sephiroth, then detonating sigil, managing to damage Sephiroth with the all of the power while Chaos Vincent shot at him with the Death Penalty, creating explosions with each shot.

Both stood side by side, looking ahead. To their dismay, Sephiroth rose from the smoke, still ready for more. "Is that it?"\


"I'm sorry I forgot", Cloud apologized to Zack.

Zack put both hands on Cloud's shoulder. "You don't have anything to apologize for, buddy. Stuff like that can mess anyone up."

"Yeah", Cloud sighed, then looked up at Zack. "Thanks Zack…..for everything."

"Like I said", Zack reminded Cloud. "You're my living legacy….and also a lot more. You beat him before, you can do it again. Good luck."

Cloud nodded as Zack and Aerith held hands, with Cloud suddenly floating away. Aerith smiled at him. "Good luck, Cloud."


Sephiroth had gained the upper hand, and Chaos Vincent had been sliced all over, with Sephiroth then blasting his face as he fell down, transforming back into normal, groaning in pain.

Genesis's Rapier glowed as he clashed against Sephiroth again, but Sephiroth was still stronger and faster, as he managed to slice Genesis in the gut and shoulder, sending him falling down as well.

Most of the others were down too, having been defeated easily. But Sephiroth would kill them all after humiliating Cloud to show him how he couldn't protect any of his loved ones.

Tifa was still up and tried to sucker punch Sephiroth, only for him to catch her fist. Sephiroth gave her a smirk, and Tifa was chilled to the spine as she remembered the last time he'd looked at her like this.

Just before he could slash her, there was a bright light. Sephiroth turned to look at it and was blown away, Tifa falling down.

All of them then looked up to see Cloud descending, a glowing golden aura around him and a white wing sprouting from his left shoulder.

Sephiroth chuckled, a purple aura around him now, both archenemies facing each other.

"I told you Cloud, I will never be a memory."

"And I told you to stay there."

The rest staggered up, knowing it was about to begin now.


Next chapter is the final fight and ending.

Due to the ending of Dirge of Cerberus, figured Genesis could show after all. Imagine Weiss is still recovering.

Hope all enjoyed and see you all next time with another chapter.
