The Group reached the Vault of the Ages as they saw Apocalypse standing in front of the machine and from left to right, Sabertooth, Quicksilver, Emma Frost, and Polaris were seen in the containment pods unconscious.

"You fools. You should be thanking me, not pursuing me. I'm the one who showed you the X-Men and Brotherhood could work together along with Spirit Force and the Reformed Society. You're stronger for it." Apocalypse said.

"I will admit one thing. This kind of experience has kind of been unexpected for us. I have never imagined that I would have taken part in something like this." Cheetah said.

"But it was through this experience that we were able to learn and understand each other more and more. That's why we were able to defeat your Horseman." Ace said.

"And now it's your turn, Apocalypse. We're ending this here and now!" Zamazenta said.

"You put a stop to me? Hahahahaaa! I don't think so. Even as we speak I have the Harmonic Powers of four mutants flowing through me. With each second I become stronger, faster, more impervious." Apocalypse said.

(Cue- Battle for a Future to Believe In- Tales of Xillia)

"That doesn't matter for people like us. You will soon see for yourself the bonds that have been forged!" Zamazenta said.

"You can gain as much power as you want, but like all the foes we've fought before, that's never stopped us before, and we're not letting it end here!" Ace said, activating Celestial Force with his eyes closed. "Let it be done!" he said, opening them to show prismatic eyes.

"That's good. Because I think you're going to find this fight an exception...exceptionally painful. Hahahahaaa!" Apocalypse laughed.

"Onward!" Zamazenta said.

"There's no way in hell I'm losing now!" Stahn said as fire surged around him. "Kouou Tenshouyoku!" he called, dealing a few spin slashes before ascending into the air as the image of a phoenix formed over him, both phases hitting Apocalypse multiple times.

"Winds of the northern sky...give me strength! Raptor Lance!" Riesz called out as magic eagle wings formed behind her as she then hovered over the battlefield darting toward and stabbing Apocalypse with a flurry of quick, explosive strikes.

"Don't quit on me yet!" Duran said as he dashed towards Apocalypse before throwing his sword into the air as he unleashed a furious onslaught of punches as purple lightning surged from each strike before finishing with a powerful slash. "Hellion Fury!"

"Coming through!" Belladonna said as she charged at Apocalypse.

"I'll lend a hand. Dark Force!" Koren said as he attacked Apocalypse with exploding spheres of dark energy.

"Your future is no more!" Spade said, donning his dark armor. "Finishing Strike...Dark Ravager!" he called, unleashing a flurry of berserk sword strikes and gauntlet punches before finishing with a powerful blast of darkness.

"Time to clock this guy. Behemoth Bash!" Zamazenta said as he glowed red and made an impact at Apocalypse.

"I will send you straight to hell!" Magress said. "Finishing Strike! Judecca!" he called, flying towards Apocalypse and dealing multiple powerful thrusts with Leomurg before trapping him in an orb of darkness and launching Leomurg straight at it, causing the orb to explode into darkness as it formed into multiple spears as they launched through Apocalypse in midair.

"Time for my own brand of red hot." Agito said, throwing his knives at Apocalypse as they were coated in fire.

"Come on, Neptune. Let's finish this." Cheetah said.

"Right." Ace said. "All my friends' hopes and dreams rely on this single shot!" he said as they both charged toward Apocalypse.

Cheetah sliced at Apocalypse with a flurry of slashes all across his body before leaping out of the way of Ace's shot.

Ace struck Apocalypse with both forms of all six of his Celestial Arms before distancing himself as he drew Breidablik as it began glowing a prismatic color. "This is the end for you! Aether...STORM!" he called, firing a massive rainbow beam as silhouettes of the Six Heroes and their Eidolon forms manifested as it engulfed Apocalypse.

"Noooo!" Apocalypse yelled as electricity began surging from him and images of each of the captured mutants appeared over him as their voices overlapped as Apocalypse soon fell to the ground, as he began to vanish into the mists of time.

"*Pant* *Pant*" Ace said as he reverted and collapsed onto one knee. "...It's over, right?"

"Yes… It's finally over." Cheetah said.

It was later outside of the Pyramid as the four groups and their ships were seen as the sun was rising.

"Everyone is safe and Apocalypse is defeated, Erik." Professor Xavier said with Wolverine, Storm, Beast, and Cyclops around him.

"Defeated, yes. But not destroyed." Magneto said as Mystique and Sabertooth stood behind him.

"True. But we'll be prepared should he ever return." Professor Xavier said before turning to Ace and Cheetah. "And I am hoping we can count on your help again as well."

"Don't worry. If he returns, we won't let him have his way." Cheetah said.

"Yes, you can count on us." Ace said.

"Ever the optimists, eh, Charles?" Magneto said.

"I'd say a certain someone I know has been rubbing off on me." Cheetah said.

"Yup, he has that kind of influence on everyone he meets." Ace smiled.

The Brotherhood then eventually left as it was just the X-Men and the two groups.

"So what is next for you and your comrades, Minerva?" Professor Xavier asked.

"Hard to say. We haven't exactly jotted down a course for anywhere." Cheetah said.

"Well there is that one thing concerning Ehto. And the Isekai Heroes as well." Ace said.

"Well, when you think about it with that info… There is...one place we could go in that case." Cheetah said.

"What is it?" Al asked.

"There is a world in the Adventure Universe reminiscent of World War I Germany. It's probably not the best place, but it's as the saying goes. 'Sometimes the best places for a hunt, are the ones least expected.'" Cheetah said.

"You just made that up on the spot, didn't you?" Luke asked.

"I thought it was quite somethin'." Wolverine said.

"I hope to see you again soon." Cheetah said.

"Same here, darlin'." Wolverine said as their hands lightly brushed against each other as some of the girls from both groups lightly giggled.

The X-Men then left as well as it was now just Ace and Cheetah's groups.

"Well, this is where we part ways. For now, at least." Cheetah said.

"Yeah. Good luck in that one world." Ace said.

"We wish you luck in your endeavors as well." Riesz said.

"Yes, we're gonna try and see if we can gather information on other worlds in the Adventure Universe." Ace said. "Best place would be the Town of Tales."

"We'll be seeing you around, then." Koren said.

"Take care everyone." Miriam said.

And so the two groups went their separate ways, both on different missions to help achieve one goal for one of their comrades. Time will tell where their adventures will take them next.
