BGM-Sonic Adventure 2 OST-It Doesn't Matter (Instrumental)

Sonic: I'm Sonic. Sonic the Hedgehog. So Apocalypse is the big bad behind these outbreaks. He recruited Eggman and other mutants to help him in his conquest to take over the world. Yeah right. As if I'll allow that to happen. With the Freedom Fighters and X-Men teaming-up, he doesn't stand a chance, just like how we beaten Selene from attacking that ISO-8 lab at Ice Paradise. This is just the beginning. Let's keep moving!

Act 5: The Mutant Agenda

Apocalypse's Hidden Base

BGM-Mega Man ZX Advent OST-The Chosen One

Apocalypse crosses his arms to keep his focus on his computer screen, displaying footage of each member of the X-Men and the Freedom Fighters. The ancient mutant has been utilizing Eggman's Egg Flappers to secretly spy on his enemies. Studying them. Testing them, while his forces are wreaking havoc around the world.

"The test is going smoothly." Apocalypse says ominously. "The Mobians are revealing their potential. The Freedom Fighters, though small, has strength that is admirable. Especially the blue hedgehog known as Sonic. His speed and strength are a cut above the rest. To be capable defeating Selene in such a way is rather impressive." He says, watching footage of Sonic's recent fight against Selene at Ice Paradise.

While the eternal mutant was talking to himself, Eggman walks into the room alongside Orbot and Cubot. "I told you Sonic would be a nuisance once he learned I'm involved in your plans." Eggman says to his new boss.

"That is why I ordered Selene to test and capture him, but she has failed. He would've made a worthy lieutenant." Apocalypse replies calmly, saying he wanted to turn Sonic into one of his Horsemen.

"I don't see how you can control that rebellious hedgehog to work for you." Eggman replied.

"I have my ways. Just like how I convinced you to help my cause." Apocalypse calmly insults his human lackey, much to Eggman's annoyance.

"It's okay, boss. Being a lackey isn't all bad." Cubot fails to comfort his master with his words.

"Now you know how we feel." Orbot sassily remarks, angering Eggman enough to kick his lackey bots across the room.

"Why are you testing the Freedom Fighters and the X-Men anyway? Is it to study their strengths and weaknesses?" Eggman asks the super-mutant with curiosity.

"To search for the strong and dispose of the weak. That is how I've always lived." Apocalypse answers, as he is a mutant that devotes his entire being to the survival of the fittest mentality. "The Mobians and the Faunus. For all intents and purposes, they were Mobius and Remnant's counterparts of Mutants respectively. I want to test if they share the same potential. Besides Sonic, the Faunus girl of the X-Men also intrigues me. She has shown promise for her species. My studies suggest that a Faunus' 'Aura' and 'Semblance' are naturally stronger than a normal human." Apocalypse claims, while watching footage of the Faunus X-Man, Blake Belladonna, as he has become interested in her and her species.

"That Belladonna girl shows promise alright. Promises to be utterly annoying alongside those other Huntress brats she's grouped with! They always ruin my fun whenever they're hanging out with Sonic! One of them stopped the freakin' sun I was going to use to win the war! Can you believe that?!" Eggman complains, venting off his anger and frustration of Team RWBY.

"You don't say…" Apocalypse mutters to himself, as he seems interested in Team RWBY and their capabilities. The eternal one slightly turns his head facing Eggman as he says to him, "My army of Infinites are nearing perfection. It is time to move forward with the next phase of my plan and collect the Xavier Protocols."

"The what?" Eggman questioned him with a confused expression.

"Doomsday plans created by Xavier to defeat the most powerful mutants, including his precious X-Men in case any of them become a threat to the planet. I want those plans to utterly destroy them. In the meantime, Doctor, are you ready to prove your worth?" Apocalypse explained.

Eggman sinisterly chuckles, "Of course. Thanks to your generous teachings, I'm finally grasping the power of Celestial technology. Do not worry yourself, eternal one. Everything will go according to plan." He states with an ominous smile that spells doom for his enemies.

Meanwhile at Splash Canyon Zone…

BGM-Sonic Riders OST-Theme of Splash Canyon

"RAAAAAAH!" A large, hulking Test Subject roars as it hurls a giant rock at Sally, who jumps away from the attack while saving a young mutant child in her arms.

"And now we have Hulk-size Test Subjects to deal with. Great. Could use a little help here, guys?" Sally responds as she gets the child to a safe place.

The cybernetic bruiser rushes to attack the princess with a deadly punch only for their attack to be swiftly caught by Colossus. "Do not worry, princess. This brute is strong, but he is no Hulk. Or me!" He claims as the steel hero knocks out the cyborg with a powerful uppercut from the jaw.

Sally's team have been tasked to protect a mutant village in Splash Canyon Zone from Apocalypse's deadly forces, as the heroes do their best to prevent them from invading the little village. Nightcrawler briefly lock swords with an Egg Knight before overpowering it with a spinning slash. He teleports around the area striking down multiple Badniks before they detected him coming. He reappears with a taunting chuckle before he was struck down in the back by a Test Subject equipped with Iso-8 powered energy blades that can theoretically slice air molecules in half.

Sally quickly runs pass the teleporter as she says to him, "I got his front! You get his back!" She blocks the cyborg's energy blades with her Ring-Blades, locking him into position as Nightcrawler ambushes him from behind with a teleporting sword strike that knocks him out.

"Quick thinking, prinzessin." Nightcrawler compliments the acorn princess with his German accent. "I say, we are doing a good job protecting this mutant village from being ransacked."

"Good. We can't allow Apocalypse to kidnap any mutants for their MGH and use them to power his forces. We need to hold them off and take out their commander." Sally replies.

Meanwhile, Bunnie just blasted an enemy dropship outta the sky and defeat some aerial enemies, while Tails fends off the goons from attacking the village's terrified citizens. "Why are these fiends attacking us? We just wanted to live in peace." The mutant mayor of this village says while trembling in fear.

"Don't worry. Things will go back to normal once we deal with these creeps." Tails assures him while using his twin-tails to smack around Infinites and Badniks alike.

Sally strikes down another Badnik as she contacts Wolverine through her ear comm and asks him, "Wolverine, are you doing okay? Is Omega Red giving you trouble?" She asked him.

BGM End

BGM-Marvel Ultimate Alliance 3 OST-Code Red

Next to a big river above a large waterfall, Wolverine is being choked to death by deadly coils belonging to the Russian-born mutant mercenary that he hates a lot known as Omega Red. "A little bit!" Wolverine told Sally while viciously having a hard time breathing and escaping from Omega Red's tentacled grasp.

"My coils will drain your life, Logan." Omega Red proclaims with a sinister smile, as the Russian mutant slowly drains Wolverine of his life force to make himself stronger.

"Chew on this!" Knuckles yells, surprising Red with a brutal attack to his cheek that sends him flying over the river, freeing Wolverine from his coils.

Omega Red recovers just as he's under an assault from Psylocke's psy-blade strikes. He clashes with his Carbonadium tentacles and fights evenly with the telepathic ninja. "Give it up. I don't need to read your mind to know I'm holding the advantage." Psylocke taunts him.

Omega then laughs as he shouts, "As if! Omega Destroyer!" flailing his tentacles in all directions that knocks back the telepath. Psylocke grunts in annoyance as she uses her telekinesis to immobilize his tentacles in midair, leaving him stun and shock, "What?!"

Wolverine takes advantage of his surprise state as he dashes towards his foe with a mighty roar while his claws pop out. "Berserker Barrage!" The wild hero rapidly slashes his claws on Omega Red before throwing a powerful strike that knocks him down momentarily.

"Ever gonna explain to me why a scumbag like you is workin' for Apocalypse?" Wolverine snarls as he demands an answer on Red's allegiance to the ancient mutant.

"He has promised me my own domain to rule in his new world order. But I would have done it for free had I known I would get the chance to crush worms like you." Omega Red answers with a disturbing smile that doesn't faze the heroes a bit.

"You ain't getting' that chance. Not today. Not ever!" Wolverine declared, threatening him with his claws.

Omega Red remains unfazed with a smirk on his face as he throws a tentacle at a large tree next to the heroes and tears it down on them. Wolverine quickly rips the falling tree to shreds just as he and his pals get viciously whip onto the river by Omega. As the evil Russian runs towards them, Knuckles burrows underneath the river for a surprise attack while Wolverine blocks his foe's punch with his indestructible claws. Omega Red leg sweeps Wolverine, knocking him off his feet as he gets utterly punch down. Psylocke tries to slash him from behind, but Omega blocks her strike and entangles her with his tentacles. Just as he reels her to her defeat, Omega was in shock when the ground suddenly rumbles and erupts a pillar of water on his face, followed by Knuckles who pummels him to the sky with a watery spiral uppercut.

"It'll take more than that to beat me, rodent!" Omega Red remarks, throwing his tentacle at Knuckles to bind him while in the air.

"Hey!" Knuckles shouts, as he is pulled into an aerial combo of deadly life-sapping tentacles before being slammed brutally to the ground.

"You will make for a nice appetizer." Omega Red taunts the weakened Knuckles as he throws two tentacles down on him.

Fortunately, Knuckles still had enough strength to stand and grab the tentacles before they entangle him, much to Omega Red's surprise. "You're not getting me with those again!" Knuckles declares as he ruthlessly throws the mutant onto a cliff above the waterfall.

While recovering, Omega Red is surprisingly tackle off the cliff by a roaring Wolverine. "Wolverine, you…" Omega snarls.

"Hope you know how to swim." Logan remarks as punches his foe in the face while falling down the waterfall.

Knuckles and Psylocke rush to the cliff as they watch the arch-enemies beating each other to a pulp while falling from a large height. "Wolverine!" Knuckles shouts in concern for his friend.

Wolverine and Omega Red continue trading violent blows at each other while falling down the waterfall. Wolverine keeps slashing with his claws while Omega Red keeps smacking him with his tentacles. As they fall closer to the large river below that might kill them, Wolverine lets out a mighty roar as he furiously grabs his foe by the chest, stabbing him through his sides while allowing Omega Red to take the full blunt as they crash headfirst into the river together, causing a large splash.

BGM End

Knuckles and Psylocke meet up below the waterfall as they stare at the river where Wolverine and Omega Red crashed into, wondering if either of them survived. "Is he still alive?" Knuckles asks the mutant ninja.

The telepath concentrates her mind as she scans the area searching for their friend and their enemy. After a little moment, she smiles and responds to the echidna, "There's nothing to worry about."

At that moment, an unconscious Omega Red was thrown out of the river behind the heroes as Wolverine walks out of the river, reuniting with his friends after surviving the crash thanks to his highly impressive healing factor. "I hate gettin' wet." Logan snarls.

"So you don't like taking showers, then?" Knuckles quips with a grin, happy that his ally is still alive.

Logan growls at the echidna, "Don't make me use you as a sponge, furball."

Then, Sally contacts Wolverine to ask for his team's status, 'Wolverine, what's your current status?'

"Red's down. Have you taken care of his little army?" Logan replies.

'We did. His forces are down and the village is safe. And there hasn't been any reports of new outbreaks, so I think it's best we regroup at the Sky Patrol. Heard that Cyclops' team was successful in their mission at Ice Paradise, so we're all returning to the Xavier Institute and focus our attention locating Apocalypse.' Sally told him.

"Sounds good." Logan nods, as he turns off his comms and looks at his teammates. "You heard Acorn. We're headin' back to the mansion. Hopefully the Professor have found somethin' while we've been out here partyin' with Apocalypse's goons." He said with a dry joke, as he picks up the unconscious Omega Red and walks with his teammates back to the Sky Patrol.

X-Mansion

Inside the basement of the mansion is a massive spherical room with a lonely bridge, where Professor X is wearing a special helmet that is helping him scan the globe for any signs of Apocalypse. By his side is Blake and Sir Charles, who is thoroughly impress with Xavier's machine.

"Such wondrous technology. Cerebro never cease to amaze me. A device to detect mutants all over the world." The scientist hedgehog voices his lovely opinion on the mutant-detecting device, Cerebro.

"Not just mutants. It can also be used to detect Humans, Mobians, Faunus, basically every living being on the planet. It has helped us save a lot of lives, especially when new mutants uncover their powers and are being hunted by the MRD. Only a telepath like the professor can use Cerebro to its fullest potential." Blake explains Cerebro to the aged hedgehog.

"And I thought my Roboticizer was impressive." Uncle Chuck jokes with a smile.

Xavier sighs as he takes off Cerebro and says, "Unfortunately, not even Cerebro is doing us any good locating Apocalypse."

"How?" Blake asks.

"Apocalypse knows about Cerebro, so it's likely he's using his technology to hide his presence." Xavier answered.

"Then how about Eggman? He's working under Apocalypse. If we can find him, he could potentially lead us to him." Uncle Chuck recommends they search for Eggman instead.

"I'll try. It's rare I use Cerebro to locate a human, but I'll give it my best shot." Xavier remarks as he puts back on Cerebro. He closes his eyes as he uses Cerebro to find any trace of Eggman that'll lead him to Apocalypse. After a moment of scanning the globe for their enemies, he gasps in horror and shock as he opens his eyes, remarking on what he saw, "Oh no…"

"Professor, what's wrong?" Blake asks him as she wonders what got him suddenly spooked.

Xavier quickly turns around facing her and Chuck as he urgently says, "Contact the rest of the X-Men and Freedom Fighters immediately. We don't have a lot of time."

"What's going on?" Chuck asks the professor.

"Genosha is under siege." Xavier answers with a serious expression on his face.

Genosha

BGM-Sonic the Hedgehog (2006) OST-Dr. Eggman Appears

Similar to the former island of Menagerie, Genosha is the island nation that is considered paradise for all mutants who seek sanctuary from being hunted and discriminated by humans. That won't stop all humans from trying to eradicate them, like Dr. Eggman launching a horrendous assault onto the island with his terrifying Egg Fleet, sending out Badniks and Infinites to destroy everything on the island as part of his plan to conquer the little nation in the name of Apocalypse.

"There is no escape for you, mutants! Watch as my superior genius surpass your crazy powers as I conquer your little island!" Eggman laughs maniacally from the bridge of his central battleship.

Two mutants are seen watching the onslaught from the balcony of a large palace. One of them is the beautiful, yet deadly shapeshifter, Mystique, and the other is Wolverine's ferocious rival, Sabretooth. They stand at the balcony in silence, waiting for their master to appear to save them from Eggman's attack.

"How foolish is this human to attack my home with his army of machines?" A middle-aged mutant in red, wearing a purple cape and a helmet that blocks telepaths remarks coldly to the assault as he walks towards the balcony with his followers. "Does he not know who I am? Who rules this nation with an iron fist? I will show him who is superior. He will regret going to war against the Master of Magnetism." The self-proclaimed savior of mutantkind and ruler of Genosha, Magneto, introduces himself next to his Brotherhood of Mutants as he is ready to go to war against Dr. Eggman.

KFX Here: Magneto returns after a long absence and is ready to defend his home from Dr. Eggman, which should be pretty easy considering he can control metal. And in case anyone is wondering what Blake's X-Man costume looks like, it's the same uniform from the movies as a little reference.

D.N. Works: Adam Taurus will not make an appearance in this story. This is primarily a Sonic/X-Men crossover with Team RWBY as important guest stars.

XenoSlayer983: Haven't watched The New Mutants trailer. Not really interested to begin with.

Guest 1 (Chapter 6): I'll stop writing stories when I stop having ideas, which won't be for a while. If you're getting tired of my stories, then simply don't read them. No one's forcing you to read them.

Guest 2 (Chapter 6): I dunno. That Parker Luck loves to work at the wrong moments.

Next time: Battle at Genosha! The Man with the Master Plan vs. the Master of Magnetism!
