Sonic: I'm Sonic. Sonic the Hedgehog! Finally took down The Hood only to find out he doesn't have the Tablet anymore. Turns out he sold it to a ninja clan called The Hand. Basic. Doesn't change the fact that they're dangerous and need to be stopped.

Volume 1 Issue 9: The King of the Iron Fist

Somewhere in the Unified World. (1 Day Since The Convergence)

BGM-PlayStation All-Stars Battle Royale OST-Heihachi Arcade Opening Song

A mysterious Japanese man stands atop a cliffside overlooking a forested landscape. This man is not of this world as he sports a distinct style in both design and evil. He is outfitted in a black gi with a tiger head design on the back. And his black hair is like a longer version of Wolverine's. He stands proudly on this cliff, oblivious that he is in an unknown dimension. For all this man cares about, is power.

"Finally, after all those years of research. The formula has been perfected. And the results are astounding." The Mysterious Martial Artist begins monologuing while clenching his iron-like fist. "Ah, to be young again! The whole world looks brand new and is mine for the taking." He cracks his knuckle with the scowling strength of a king. "And now I have the chance to test my abilities. To push myself harder than ever before. My pathetic family and their weaknesses will have to wait." He crosses his arms that discharge scary blue electricity. A power akin to Jin Kazama's. Amidst his monologue, his curious gaze spots a certain woman flying through the sky. It is Nu-13, last seen since the Prison Raft Breakout. Her whereabouts have been unknown and her current objective is a mystery. Doesn't stop this otherworldly warrior from taking an interest in her and this dimension. "Warriors, the likes of whom I've never encountered before, stand ready to fight. But are they ready for the new Heihachi Mishima?" wondered Heihachi Mishima, The King of the Iron Fist.

Elsewhere…

BGM-Dragon Ball FighterZ OST-Synopsis

The Hood sold the Lifeline Tablet to Elektra, who's currently affiliated with the ninja clan known as The Hand. The Dimensional Avengers wasted no time boarding their Aven-Jet Prime and taking to the skies en route to their latest destination, Mistripoor. It'll be some time until they get there. A time they are using to relax. Sonic is doing his atop the jet, leaning on it with his peaceful eyes closed and his cupped hands being used as a pillow. Inside, Tails is piloting their ship while the trio of Ruby, Pit, and Naoto are behind him playing a fun handheld game with each other.

"Man, sucks I couldn't stay with you guys. We had a blast together." The tiny hologram of Ms. Marvel complained from the cockpit, having been assigned to a different mission.

"Sure did. But the world's still in chaos and there're people that only you can help. That's the life of a hero. Have fun in Team Beta." Tails smiled, cheering her up.

"Will do. Good luck finding the Tablet. Bye, guys!" Kamala smiles back, waving goodbye to her new friends.

"Right back at ya. Thanks for everything." Naoto grinned, grateful to her for guiding him through the Unified World at the beginning.

"Let's hang out again once we're all done." Ruby happily said to her new costumed comrade.

"Oh yeah!" Kamala expressed an excited gesture before ending the holo-chat.

"Back to me kicking you guys' butts!" Pit teased, returning his fierce focus back to their video game.

"No you won't!" Ruby retorted, following suit alongside Naoto.

Nearby, in the midst of Jin and Yang's holographic ping-pong competition, most of their friends are playing a rousing game of Go Fish. Amy, Weiss, Blake, Lucina, Palutena, and X are the players. Their pool is almost depleted. Lucina tells Blake to, "Go fish.", and glances at her draw a card from the pool before returning her eyes back to her set. "I cannot believe The Hood sold the tablet to The Hand. Who are they again?" Lucina asked.

"Besides having a name as lame as 'The Hood'? Just your typical clan of ninjas that want to conquer the world. I fought a few during vacation." Blake replied, casually looking through her own set.

"From gangsters to terrorists to ninjas. This tablet is very popular." X commented, then asks Weiss, "Got any threes?"

"I suppose there is an appeal to eternal youth. Not looking forward to growing wrinkles." Weiss quipped, handing him his two threes.

"I'm a reploid. I won't have that problem." X smiled innocently.

"Lucky you." Weiss snarked.

"Any eights, Amy?" Palutena asked.

"Guessin' I'm fishing." Amy grabs the last card from the pool, resulting in the game ending and Palutena being the winner with the most books.

"I win. Woohoo." Palutena expressed adorably.

"No fair! I know you cheated with your god powers!" The irritated Amy accused her.

"Whaaaat? You're crazy." Palutena quips with a sly look that implies her mischief.

"By the way…You're better than I thought." Jin said, complimenting Yang after they completed their round of ping-pong.

"I've had a lot of practice." Yang gestured cockily.

"Why don't I take you on next, Jin Kazama? Then we'll see just what you're made of…" Knuckles challenged him.

"Let me get you a stepping stool…" Yang teased.

"Don't pamper me, Bushy Blondie!" Knuckles snaps furiously at his blonde rival, but of course she is having too much fun ignoring his insults.

"What's their deal? They're always at odds with each other." Jin asked Amy, curious about Knuckles and Yang's friendship.

"They're rivals. Always trying to prove who's stronger. That's just how they get along." Amy answered, getting her cards ready for another round of Go Fish.

BGM End

Yang reaches for the stepping stool that is near Spider-Man's seat. In that instant, she forgets what she was doing and stares at him with sympathetic concern. Peter has been spending this flight minding his own business and being alone, like Sonic. But unlike him, he appears broody. Staring out into space through the window. He hides it well but Yang sees the truth. The man is still feeling guilty about letting the Convergence happen. "Pete…?" Yang mutters at him, wondering what she can do to lift his spirits. An idea lights up in her head that gets her into giving her ex-boyfriend a cheery smile, "Hey Webs! Wanna play ping-pong with us?"

"Huh? No thanks. I'm good." Spider-Man responded after being snapped out of his depressive thoughts.

"Okay. How about you share a story?" Yang asked.

"You wanna hear another of my crazy adventures?" Spidey commented.

"Yeah! They're always a blast to listen." Yang beamed.

"Okay. Which one are you interested in?" Spidey asked her.

"Give us one related to Adam Warlock so we can know him better." Yang requested.

"Alright." Feeling like himself again, Spidey gets up from his seat to move to a position where he can share a tale with the rest of his friends. "Story time, kids! Lemme tell you 'bout the time half of all life in the universe was erased from existence. I like to call this one 'The Blip'." He announced, clapping to his whole team to get their attention, even Sonic by knocking on the ceiling.

"This is gonna be good." Weiss quipped.

BGM-Mega Man ZX OST-Metallic Soul (Tunes Ver.)

Spider-Man flashes back to the past as he begins his tale. Back to a time when a Mad Titan got ahold of a cosmic gauntlet and used its infinite power to literally snap half of reality out of existence. "A few years ago, the worst disaster to have ever hit humanity came out of nowhere. Half the world was dead. Killed by a tyrannical despot that seized control of what has been described as the greatest power in the universe. The Infinity Stones. The Mad Titan was so in love with Death that he decided to impress her by annihilating exactly one half of creation with just a snap of his fingers." He said, recalling New Yorkers collapsing into dust by the cosmic murderer.

"With just a snap? Oh man." Pit expressed his shock.

Peter continues, recalling Warlock coming to Earth's aid in its greatest time of need. "That's what Reed Richards said on the news. Adam Warlock soon showed up and helped him prepare a retaliatory strike consisting of what was left of Earth's Mightiest Heroes. Yours truly included because of my considerable talents. Recruiting a 15-year-old kid that was too used to beating muggers and trigonometry exams screamed desperation. Made ten times louder when requesting help from your worst enemies like Doctor Doom." He remembers himself joining the task force with heroes like Iron Man and Psylocke, and villains like Juggernaut and Magneto. "Captain America was appointed the leader of the task force. Together, we took the fight straight to the Titan at his floating space palace. It was THE ultimate cosmic battle that decided the fate of the universe." He recounts their almighty team fighting the Titan at his palace in outer space. "Everyone versus him. And we were hopelessly outmatched. Us heroes gave it their all, some making the ultimate sacrifices to reveal even the tiniest opening for a counterattack. Even cosmic beings like Galactus came to lend us a hand. In the end, it was Warlock that saved the day and took back the Stones, restoring everything back to normal before making certain that no one abuses their power ever again. That was the last time I seen him." He finished his tale that ends with the Titan defeated, Warlock in possession of the Infinity Gauntlet, and many heroes being restored from a petrified state.

"Wow. I…I don't know what to say." Lucina said, amazed yet slightly bothered by that cosmic tale.

"Sounds like one heck of a fight. Wish I was there to teach this Titan a thing or two." Knuckles grinned.

"Would've made you my most immediate replacement. That fight was intense. First time I helped save the universe. Opened my eyes to just how big and…terrifying it is." Spidey responded, being subtle in how he was mentally scarred by the Infinity War.

"Confronting the power of infinity would do that to anyone, whether man or god at any age." Palutena commented sympathetically.

"Makes sense why the Exo Stones worry you." Blake frowns at her ex-boyfriend, recalling how bothered he was by them during that night they defeated AIM.

"The Exo Stones are just more powerful Infinity Stones. Instead of six, there're eight singularities. Each one in control of different aspects of reality. I hear the originals only work in their home dimension. But the new ones can be used in any world. Affect multiple realities all at once." Spidey explained.

"Should I bother to imagine what happens if someone evil finds these eight Stones?" Naoto asked.

"If you want to have nightmares for a couple of months, be my guest." Spidey quipped. "The Stones are too powerful together. Nothing can surpass them. Not even Super Sonic." He grimly claimed.

"Would still give a good fight." Sonic joked, peaking his head out the ceiling since he was listening to the whole story from the roof.

"Infinity vs. Infinity. Why not we collect the Infinity Stones and use them against the Exo Stones?" Pit suggested.

"No. Warlock separated the Stones for a reason. No one should wield all that power." Spidey rejected his idea.

"Hasn't stopped us from using the Stones we have. What if the worst happens and Doom or some other villain finds the Exo Eight? We'll be annihilated. We need a contingency." Weiss argued sternly.

"We do. Several." Spidey retorted.

"Nothing wrong having a few more." Weiss countered.

"A clash between infinites could very easily destroy everything we've sworn to protect. One tiny slipup and it's over." Amy argues against the heiress.

"I once wielded four Exo Stones during the final battle with Ultron Sigma. Even with the Exo Buster that was specifically designed to control the Stones, I still felt their energies overloading me." X recalled.

"Power that cannot be controlled is meaningless. Both the Infinite Six and the Exo Eight possess infinite power that our bodies will never be accustomed to. It's suicide. At best, we should control one Stone at a time." Jin commented, voicing his own opinion in the argument.

"Then let's just share them amongst each other. Use them as a team." Yang suggested.

"Perhaps as an absolute last resort. The more we use the Stones the more they corrupt us. Kill our morals and turn us into something we're not. Those negative effects intensify when used alongside the others." Tails refuted.

"Sacrifices must be made when all of creation is at risk…" Knuckles said ominously. "But we have enough on our plate as is. No time to go on another treasure hunt. Hopefully Warlock will get our message and his Soul Stone will be just enough." He hoped.

"The best method to beat infinity is by reaching outside the loop. Be unpredictable. Whatever it takes, that's the key." Spidey advised his team.

"Not to mention to have faith within your heart." Ruby added, recalling the lesson she learned during the Ultron Sigma incident.

"Yeah." Spidey nodded in agreement. "Don't worry. If the worst ever happens, we'll figure something out. We've gotten this far together." He encouraged his friends to not give up hope.

"And what of our mystery enemy? Is it possible they could be the Mad Titan?" Lucina questioned him.

"God I hope not. Think I remember Nova telling me he died during some Annihilation thing in space." Spidey answered.

"Let us hope that stays true." Lucina frowned, getting the worrisome sense that the Titan is alive and is coming to destroy everything. Which is true.

BGM End

Just then, Tails receives a beep on his radar that shows their ship nearing their destination. "Almost there to Mistripoor. Landing is gonna be a problem so get ready to jump." He informed his passengers just as the Aven-Jet enters the airspace of the giant island.

Sylvania Beach Zone, Mistripoor.

BGM-Marvel Future Fight OST-Hail Hydra!

Sylvania Beach. A hybrid beach between Sylvania Castle Zone from Mobius and Buccaneer Beach from Earth. A tropical seaside full of palm trees that is connected to castle ruins that has a magical appearance. It is also a chaotic warzone, fought between S.T.R.I.K.E. and Hydra. One grunting gesture from Captain America and STRIKE Agents follow him into battle. His vibranium shield pushes through bullets before bashing down the gunner followed by his fist smacking down another Hydra Soldier. He then throws his mighty shield, watching it curve on several more enemy soldiers and catching it in time to block the sword of an Iron Dominion ninja. Another ninja surprises him by sweeping him off his feet with their staff, but the Super Soldier is quickly aided by the martial arts of Iron Fist that blows away the Hydra allies. Iron Fist helps Cap back onto his feet, right before they spot the Aven-Jet in the sky.

"Got some friendlies!" Iron Fist announced.

The Aven-Jet zooms over the beach in auto-pilot mode. The Dimensional Avengers jumps off it and fall down, avoiding enemy fire until they land next to their fellow heroes. "Captain America and Iron Fist. Whassup?" Pit greeted his two friends in Team Alpha.

BGM End

"Glad you all could make it. Heard from Hill you'd be coming. Sounds like The Hand got their namesake on something dangerous." Captain America smiles at them.

"Understatement of the day. We're supposed to meet with Agent James Woo at a secret Recon Post inside the city. Know where we can find it?" Spider-Man asked.

"I'll show you." Cap replied, right before deflecting bulletfire from nearby enemies, "After we get past this battlefield."

"Hydra and the Iron Dominion working together? When did this happen?" Sonic noticed both factions working side-by-side, much to his confusion.

"For a while. Their invasion of this beach caught us off guard, and they took some prisoners." Iron Fist replied.

"Unfortunately, the LZ is too hot for reinforcements. We need your help rescuing the agents that Hydra grabbed in their initial assault." Cap requested their help in securing this Zone.

"On it. We'll force them to talk where they're hiding them." Jin accepted determinedly.

BGM-Marvel vs. Capcom: Infinite OST-Battle Theme #1

The Battle of Sylvania Beach begins anew now that the Dimensional Avengers have arrived. STRIKE's Alpha Team is led by Captain America and in charge of dealing with supervillain attacks, and this strange alliance between Hydra and the Iron Dominion is no exception. It'll be tough but thankfully Cap unlocked a new dimensional power. Tactical Vision. One good look and he sees the battlefield in literal black-and-white. The only exceptions are the soldiers, their weapons and bases, and the battle flow are highlighted and aiding him in coming up with the most effective strategy.

"Security Squad, bolster our defenses! Assault Squad, take on those armored guards protecting the castle! Keep 'em entertained for our Operatives to slip in through the sunken ruins! Their commander inside must know where they're holding our agents!" Captain America ordered his army, before glancing at both Sonic and Lucina, "You two with me!", and running into defending their bases with him.

The trio confront a large enemy horde about to overwhelm STRIKE Agents. Captain America shield-dashes into the fight and throws a quick combo that pushes the enemy back. One punch stuns a Hydra Soldier, allowing Sonic to fly over the ducking captain with a kick that knocks him down and shoots out a Sonic Wave that sweeps more soldiers. Lucina easily holds her own against a squadron with Falchion but doesn't notice an Iron Ninja about to ambush her. Cap does and throws his shield to aid her, having it bounce off enemies near Lucina so she can catch it and bash the ninja down with it in swift fashion.

"Thank you." Lucina said to the captain.

"You're welcome." Cap responded.

"Sword, Shield, and Sonic. There's no better combo." Sonic joked, beating down enemies at supersonic speed.

"Ego's reminding me more of Iron Man with every meeting." Cap quipped, blocking bulletfire from Hydra Rifle Troopers while ordering Lucina to, "Swing your sword on the sand!"

The Princess Exalt complies, splashing sand on the troopers' eyes to blind them and make it easier for the team to beat them. "Your tactics are as astonishing as Robin's." Lucina complimented.

"I try my best. With extra help from my Convergium Particles." Cap replied humbly.

"You mean you unlocked your own Cross Art?" Lucina questioned.

"Yeah. It's strange. Here on the battlefield, I can…Well, I can 'see' things." Steve said, explaining his Tactical Vision Cross Art to them.

"See things? Like what?" Sonic commented.

"The enemy's strength, their weaponry, the flow of battle…Like my brain's been given another dose of the Super-Soldier Serum to identify anything useful to plan around." Cap explained, swiftly using his Cross Art to better sense and block incoming attacks.

"Robin boasts of a similar skill. Could our Convergium Particles allowing us to adopt certain traits from people across the Crossverse?" Lucina theorized.

"That's a theory for Tony and his science team to answer." Cap retorted, as they continue supporting their fellow STRIKE Agents.

Meanwhile, the Assault Squad is supported by Iron Fist, Yang, and Jin in fighting the troops guarding the castle. Hydra Armored Guards are the most loyal and resilient that are trained to sacrifice themselves for the cause. Iron Fist plays with them while showing off his mastery of chi, uppercutting a horde with a dragon-shaped energy punch that leads them into his skilled combo of kicks and elbow strikes and a large dragon blast that both blows them away and amazes his fellow martial artists.

"Can see why you're called Iron Fist. Your Ki is unlike anything I've seen before." Jin commented.

"Think you mean 'chi'. That's what he calls Aura in his world." Yang quipped.

"Same difference. Now indistinguishable thanks to the Convergence." Iron Fist smiled.

"Seriously?" Yang frowns in confusion.

"Our spiritual energies work differently depending on your world of origin. Distinct but not by much. This Unified World removes that distinction and alters our spirit to be in harmony with others." Iron Fist lectured, basically saying that Chi, Aura, and Soul from Mobius have fused together.

"Sounds more of a X-Aura than Spidey's." Yang teased through the comlink.

"I get the message. From now on I'm calling my awesome power X-Factor. Less corny." snarked Spidey, web-pulling a large rock to flail on enemies in a spinning acrobatic way.

"Try out that Fire Fist technique we were training on. Can sense your energies have been strengthened." Iron Fist advises his pupil.

Yang complies, taking a fighting stance against incoming Hydra Soldiers. She feels her Aura levels have increased substantially and twice as intense than before. And thanks to her summer training with Iron Fist, she has better control over her Aura and learned to manifest it in ways beyond a Semblance. She propels her fists together forward and gathers chi that resemble purplish-orange flames. Once fully charged and her enemies are about to strike, the dragon huntress fires a powerful flaming burst that knocks down her enemies. "Whoo! Finally got it this time." She cheered.

Jin tests out this unified chi himself with his Double Chamber Punch on a Hydra Soldier, executing two powerful punches that electrifies the goon with projectiles he never could unleashed in his homeworld. "Not bad. A compensation if we're unable to activate our Convergium Particles. Would be better if I had stronger test dummies." He commented whilst insulting his enemies.

"There's always Knuckles." Yang snarks with a teasing smirk.

'I heard that!' Knuckles angrily retorted through the comlink.

"We'll have a spar after we recover the Tablet." Iron Fist suggested, as the trio continue fighting with their chi powers.

Cap's plan is working so far. While the main guard is distracted defending the front, STRIKE Operatives attempt to infiltrate the castle through some watery ruins. Knuckles, Tails, and Blake lead this squadron with their expert swimming skills, traveling underwater where several Iron Ninjas await to ambush them. Knuckles is quick to counter them with his Drill Spin Attack that strikes them down in quick succession, leading to him tunneling out their exit inside the castle and using Tails to surprise their enemies with his Fire Dunk move.

"Where did they come from?! Attack! Get them out of here!" The Hydra Commander ordered his troops, watching them defending him from STRIKE with their weaponry.

"Give me a shield!" Knuckles gestured to Blake.

Quickly, Blake uses Earth Dust to create a stone clone that's strong enough for Knuckles to use as a makeshift shield against the bulletfire. He barges right through it and swings his shield to unleash a shockwave that blows away the goons that were protecting the Hydra Commander. A powerful three-hit combo from the stone clone was enough to knock down the pathetic commander and be threatened by Tails's blaster and Blake's sword. "Where are you hiding your prisoners?" Blake coldly asked him.

"T-They're in an outpost! Near the Bamboo Forest, underground! Don't hurt me!" The scared Hydra Commander claimed.

"Got that, Captain?" Knuckles asked through the comms.

"Yeah! On our way now! Rest of you wrap things up out here!" Captain America responded from outside the castle, racing alongside Sonic and Lucina to the hidden Hydra Outpost.

BGM End

BGM-One Piece: Pirate Warriors 2 OST-Frenzy

"Not so fast!" But then, out of nowhere, a large Mobian Ox in fearsome metal armor crashes down from the sky to intercept the surprised trio. A single swing of his magical Tremor Mace was devastating enough to send them flying across the battlefield. Through trees and ruins until their backs slide backwards on the sandy beach.

"You guys good?" Sonic grunted, taking a moment to recover from that surprise hit.

"Yeah…Felt like I was hit by a truck. Who is this guy?" Cap asked, helping Lucina up while they all stare at their latest and strongest foe yet that's approaching them with a menacing snort.

"Jun Kun. The Iron King." Sonic scowled. "This's gonna be tough. He's the other ruler of the Iron Dominion and one of the toughest Mobians around." He proclaimed, recognizing the bull as another from his rogues' gallery.

"Are you saying he is married to Iron Queen?" Lucina questioned him.

"Not in the traditional sense. They don't really like each other that way." Sonic quipped, stating the Iron Couple are in a ceremonial marriage.

"We do love shutting your mouth, hedgehog." Iron King launches an explosive ground pound that is dodged by the trio then slams his mace to the ground that was packing enough earthquaking force to spread multiple shockwaves across the whole beach, harming many STRIKE Agents that were in the middle of beating up Hydra goons.

"Where's Sun Wukong when you need him?" Spidey joked, popping his adorable head out of the large sand he was buried under thanks to Iron King's attack.

"Don't see Team SSSN faring any better." Weiss responded, unaware that he was talking about another monkey that journeyed to the west.

"Why are your forces invading Mistripoor?" Cap asked, hurling his shield that bounces off the invulnerable bull.

"Why else? To conquer it. For the glory of the Iron Hydra Empire!" Iron King answered, slamming his weapon on the captain's indestructible shield.

"Iron Hydra Empire? That's the name of your alliance?" Lucina questioned, clashing weapons with the arrogant warlord.

"Yes. The leader of Hydra visited me and Iron Queen shortly after the Convergence with the proposal to unite our powers. Your STRIKE Force is an eyesore. If we are to survive in this new world, a collaboration was necessary." Iron King explained, overpowering her with a giant mace swing.

"Got that right!" Sonic hits his face with a hyperfast Spin Attack that stuns him so he can be hit by Steve's Hyper Stars & Stripes. Three rising uppercuts from Cap's shield just barely push him back, just enrage Kun into ramming into the two headfirst before bashing them again with his mace.

"Hydra's technology combined with my kingdom's strength is too much for this world! Surrender and I might make your deaths painless!" Iron King smirked, radiating arrogance expected from powerful tyrants like him.

"Thanks for the offer, but we decline!" Iron Fist snarked upon suddenly showing up to the fight, slamming the large bull down with his chi fist as quickly as Jin bombarding him with electrifying blows and Yang blasting him back with her Fire Fist. The rest of the Dimensional Avengers then show up to confront the mobian bull king just as Danny taunts him, "There's no way you can beat all of us!"

BGM End

"Then how about I have some fun with them." A certain Martial Artist chuckled sinisterly.

BGM-Namco X Capcom OST-Tekken Tag Tournament Opening

Out of nowhere comes Heihachi Mishima jumping to Iron King's side with an eager smirk that surprises everyone. "Who are you?" The curious Iron King asked this newcomer.

"Just a wanderer looking for a challenge. Was following some robot girl when I heard all this racket. You all look like the perfect dummies for me to test out my strength." Heihachi answered, having chased Nu-13 to Mistripoor.

"His chi is extraordinary. He is not from this world." Iron Fist sensed.

No one but Jin seems to recognize this mystery man. His eyes looked curious at first until he got a good sense of his ki and his eyes glare at him with an intensity he hasn't displayed to anyone else before. "Heihachi Mishima, huh?" He snarled.

Heihachi heard him, exchanging glares before reacting with shock, "Hmm…? It's…Jin? Jin Kazama? What are you doing here!? Wasn't expecting to run into you so soon."

"Who cares?! So we meet again, Heihachi!" Jin retorted.

"The former owner of the Mishima Zaibatsu and your world's Kingpin. Guessing he got here through a dimensional rift." Blake said, recalling Jin mentioning his nemesis back at the Blood Rose Nightclub.

"Just like me." Naoto remarked.

"Dimension? You're saying I'm in another world? Was wondering why things felt off. But thanks to that I get to beat up my grandson again." Heihachi grinned, surprising the heroes with his relation with Jin.

"Say what?! You didn't tell us Japanese Kingpin is your GRANDPA!" Spidey exclaims at Jin.

"I don't consider him family. Haven't in a long time." Jin replied emotionlessly.

"See you're still pissy about me shooting you in the face. Get over it, 'cause in a few minutes you'll lose your whole life." Heihachi snarked.

"I don't buy that you're his grandpa. You look young enough to be his crazy dad." Amy commented.

"Don't tell me he stole the Tablet from the Hand to restore his youth?" Palutena wondered.

"Tablet you say?" Heihachi mutters with ominous interest, then smirks, "Don't know what you folks are talking about. My new look is the result of a new experimental drug that I've been working on for a long time. But I see Jin knew who I was anyway."

"It's your horrible 'spirit'. Your looks may change, but that never will." Jin snarked.

"Pretty crazy, if that's true. They should market that stuff!" Pit commented.

"Absolutely not! That drug sounds dangerous, and I…" Weiss retorted, quickly coughing with embarrassment once her friends caught her selfishness, "Er, STRIKE should confiscate it!"

Amused by these otherworldly heroes, Heihachi chuckles at Jin, "So, what do you wanna do? Wanna fight it out right here? You commandeered the Zaibatsu while I was gone. I trust you've enjoyed bending it to your childish whims."

"You're the one who disappeared. It's too late for regrets." Jin retorted, shooting at him a threatening glare that is eager to settle the score with his nemesis.

"Wait, Jin! Under these circumstances, you can't just act reckless!" Captain America said, struggling to stop the young Mishima head from jeopardizing their mission.

"You seem confident in your abilities. Fine. We will work together for now to crush these pests." Iron King said to his fellow villain, reluctantly accepting this teamup with the King of Iron Fist.

"Just don't get in my way or you'll regret it." Heihachi snarked. Intimidating electricity discharges from his body as the old master strikes a fighting stance against those that dare to challenge his raw might. "Like it or not, we're having it out right now! This time, Jin, I will kill you, claim your Devil Gene, and become head of the Zaibatsu once again!" He declared, voicing his full intent to murder his own grandchild.

"Heihachi! I'm sending you straight to hell!" Jin declared, allowing vengeance to consume him and run recklessly into danger.

"Jin, no!" Cap exclaimed, reaching out to him in vain.

"We'll back him up! You and some others go rescue the prisoners!" Knuckles tasked the captain.

Cap nods, "Okay. Lucina, Ruby, Tails, with me!", before leading his small team into saving their imprisoned agents.

BGM-Tekken Tag Tournament 2 OST-The Strongest Iron Arena (Silver Mix)

Cap's Team runs past the tag team villains to locate the Hydra Outpost entrance. Only Iron King pays attention and wants to stop them, but is forced to stay behind and fight by the combined fists of Knuckles, Yang, and Iron Fist. Heihachi's focus is solely on Jin rushing at him with murderous intent, easily deflecting his punch with a backfist swing. The two Mishimas trade quick blows with their respective fighting styles, Kyokushin Style and Mishima Style. Jin throws a powerful punch that slams onto his grandfather's cheek, which doesn't faze him at all as the elder knocks him back with his Lightning Crush technique.

"I'm not the same man that I was before." Heihachi claims, with his head performing a narrow dodge of Jin's punch. "The formula has given me reflexes and strength I haven't felt since the prime of my youth." He grabs his grandson to give him a brutal headbutt that knocks him aback in grunting pain. "I am a young man again. The fire that burned within me now burns even stronger." He then sends his foe flying onto some ruins with his Wind God Fist. "All my old strength has returned to kill you!" He proclaimed, ready to crush his grandson with his killer Jichinsai.

"Danny!" Yang shouts at Iron Fist to help out Kazama.

"Tagging in!" Iron Fist retorted, leaving his student and Knuckles to handle Iron King.

At the last second, Iron Fist saves Jin with a surprising uppercut that forces Heihachi aback. "You seem to have some skill…" Heihachi noted.

"Fair warning: I'm registered as a lethal weapon." Iron Fist taunted by showing off his mastery over chi with his two bare hands.

"Stay out of this. He's mine…" Jin panted, struggling to recover from that beating.

"Learn to control your anger and we'll see." Danny advised, before returning his fearsome gaze at the grandfather, "Been a while since I fought a real warrior. Come on, let's see what you've got."

A shining golden aura envelops Iron Fist as an intimidating blue aura does the same to the scoffing Heihachi. Both launch cross-counter punches that knocks each other aback. Danny switches to Red Chi to increase the power of his punch that smashes into his rival's face, then switches to Blue Chi to increase his defenses just in time to block Mishima's whip-like punch, hitting him with a leg sweep before switching to Green Chi and shouting, "Fists of fury!", and unleashing a series of rapid punches that surprisingly pushes back the Mishima Master despite him blocking every blow.

"This is great! Destroying your fists will make this fight be worth the trip!" Heihachi smirked, unleashing the strength to deflect Danny's Iron Rage and hit him with his Demon Breath move that surges his lightning.

"Good thing mine's an Immortal Weapon! No youth serum can give you the strength to break the Iron Fist!" Danny staggers him with a surprise dragon blast to hit him with two rising hopkicks in quick succession.

"Cheeky brat! I am the KING of the Iron Fist! All can be broken by me in any age!" Annoyed by his title, Heihachi assaults him with one of his stronger moves: Raijin's Wrath. The Iron Fist King pummels the Immortal Iron Fist with swift yet brutal blows until he uppercuts him high into the sky. Danny then falls straight down, right into Mishima's thunderbolt-empowered punch before he knocks him down with his Shingetsusen.

Impressively, it didn't take long for Iron Fist to perform a swift recovery from that super combo. It hurt like hell but Danny is a true Iron Fist Master that is resilient to everything. Jin is similar as he regained the strength to rejoin the fight against his grandfather. Iron King is then knocked back to his partner's side, expressing annoyance at both Knuckles and Yang giving him a decent challenge.

"Ready to call it quits?" Knuckles taunted the villains.

"Hardly. The real fight starts now!" Heihachi scoffed, ready to begin the second round of this tag-team bout.

Meanwhile in the Hydra Outpost…

Several STRIKE Agents are locked behind bars in this underground outpost. Lots of Iron Hydra Troopers patrol this base with the simple task to prevent anyone from getting in or getting out. One brave STRIKE Agent tries challenging that by insulting a Hydra Guard from within his cell, "Mind letting us out already? Gonna be sorry once the calvary arrives to do it while cleaning your clocks."

"Shut up." The Hydra Guard retorts by using his electric baton to torture the prisoner into silence, "No one's coming to your rescue. The fewer of you there are out there leaves us more room to nab the Tablet."

"I'm liking this new alliance so far, but do we have to start shouting the whole 'Hail Hydra' thing?" An Iron Ninja asked, having a casual conversation with a Hydra Soldier.

"This is the Iron Hydra Empire, so yeah." The Hydra Soldier responded.

"Why not just 'Hail Iron Hydra'?"

"Ehhh, doesn't roll off the tongue as good."

"I guess."

BGM-Marvel Ultimate Alliance 3: The Black Order OST-Into the Fray

Unbeknownst to the guards is that their outpost has been infiltrated by Captain America and his crossover team. He throws his vibranium shield from the shadows with a clever tactic in mind to make this rescue operation go much smoother. It ricochets off goons and walls at blurry speeds, destroying the lock that was imprisoning that one STRIKE Agent that was tortured earlier. "Wha-?!" The Hydra Guard expressed surprise before being punched into unconsciousness.

"Warned ya." The STRIKE Agent picks up his baton and uses it to help free his comrades.

The Iron Hydra Empire is now surrounded by the heroes and the rescued STRIKE Agents. Their new alliance means squat against true teamwork demonstrated by Ruby and Lucina. Ruby initiates their Storm Slam Crossover Combination by lifting a horde into the air with a whirlwind using her Semblance for Lucina, who assaults them with relentless sword thrusts before slamming them with an electrified sword slash. Tails, in the meantime, has just finished freeing the last of the STRIKE Agents from their imprisonment, asking them, "Is everyone okay?"

"Will be once we're outta this hellhole!" A Faunus STRIKE Agent retorted, picking up a blaster to fight with.

"We've secured an exit above ground! We're heading out! This way! I'll cover our flanks!" Captain America ordered, shielding his retreating allies with his signature tool.

"Don't let them escape!" An Iron Ninja ordered her forces to unleash their relentless firepower at them.

Cap counters this by tapping into his Tactical Vision. Identifying explosive canisters around the massive force, the Living Legend bounces his shield off them and catches it in time for the successive explosions to knock out the incredible enemy horde. "I could get used to this." He smiled, enjoying his Cross Art.

"C'mon, Cap!" Ruby shouted, gesturing him to follow his team back to the surface.

Back at Sylvania Beach Zone…

BGM-Marvel vs. Capcom: Infinite OST-Drone

The tag-team showdown against Heihachi and Iron King is on its way of wrapping up in an intense fashion. Using his magical mace, Iron King delivers a giant swing that smacks Knuckles back to his fellow martial artists and bombards them with ferocious energy shockwaves that pushes them all to evasive maneuvers. Jin had enough, swinging his electrified arm to deflect a shockwave and fire an electrified sphere to stun the powerful mobian, giving Yang the opening to recoil herself to attack. Unfortunately, Heihachi intercepts with his Lightning Hammer technique that nearly knocks the huntress unconscious. Fortunately, Iron Fist tags in with his Dragon's Prey move, knocking the Iron Fist King away with a powerful one-inch punch empowered by his golden chi.

"A little help here…" Knuckles grunted, having caught and struggling to deflect Iron King's mace.

Jin helps him out with his Leaping Side Kick that knocks back the bull and strikes him with the Kazama Style 6 Hit Combo that is doing little damage, prompting Iron King to catch his last kick and taunt, "Such puny attacks don't work on the Iron King!", then slam him wildly on the ground before throwing him aside to focus his smirking glare at Knuckles and Yang.

"This guy invulnerable or what…? Nothing's working." Yang groaned, on the cusp of recovering from Heihachi's surprise blow.

"Would be easier if we had that magic fan. How 'bout you stop pulling your punches and we might get somewhere." Knuckles frowned, taunting his rival to go all-out.

"Don't see you trying!" Yang angrily argues with him.

"Keep him busy and I'll show you!" Knuckles retorted with a plan in mind.

Yang complies by tapping into her Resonance Blaze power, delivering a dashing punch at Iron King powerful enough to burst a huge shockwave upon impact. Surprisingly, her attack did little as the bull blocked it in time, blowing her away with a ferocious roar. "Don't see those kids winning against that bull. His body is as tough as my fists." Heihachi noted, in the midst of his even bout with Jin and Iron Fist.

"Don't underestimate the youth when they're working together. They're just full of untapped potential." Iron Fist argued, while Knuckles is preparing his Maximum Heat Knuckles Attack.

"Any time, Knucklehead!" Yang taunted him to hurry, firing multiple Fire Fists that were in vain to hurt Iron King.

"Focus!" Knuckles retorted.

"Hard to believe that with their bickering." Heihachi scoffed.

"That's how they grow stronger. That's what rivals do. Pushing each other to their limits and shatter them to challenge the unknown!" Jin refuted at his grandfather, recalling what Amy told him in the Aven-Jet.

BGM-Street Fighter X Tekken OST-VS Rival Battle TK Arrange 2

Knuckles's next action is about to prove Jin right. His interdimensional rivalry with Yang is pushing him to reach in deep for greater strength. His determined will to beat her, Iron King, and Heihachi is resonating with the Convergium Particles sleeping in his body. They activate and gift him his Cross Art: Earth Break. The supernatural power of the earth is now his to command as his body glows green and causes beams of green light to emerge from the ground, causing the ground to crack and break and his body absorbing the energy of the land. Just after Yang is smashed down by Iron King, the Echidna Warrior launches his Maximum Heat Attack empowered to the extreme by his new power. "LET'S SEE WHAT YOU GOT!" Knuckles roared ferociously. Yang jumps out of the way just a mere second before Knuckles slams his earthly-powered fist right into his face at unseeable speeds. That attack was too surprising, too powerful for even the invulnerable Iron King to endure. In a blink of an eye, the Mobian Bull King was rocketed right off of Sylvania Beach Zone and sent crashing into the ocean far from Mistripoor.

"They won. Guess you weren't spouting nonsense after all." Heihachi commented, whilst Iron Fist and Jin run at him from opposite sides. "None of that will be enough to conquer THIS Iron Fist King!" He shouted alongside delivering a vicious parry at them with his Raijin Stance.

Jin reels back from that painful blow that only increases his hatred for his grandfather. The Mishima Fighting Style represents everything he loathes about his bloodline and the deadly threat it expresses triggers an uncontrollable response from his Devil Gene. His devil tattoos and his third eye manifest on his forehead, and unlike during his fight with Green Goblin, his regular eyes glow red to symbolize his possession by his devil half. "Wanna bet?" Devil Jin snarked with a demonic tone that frightens Heihachi. He strikes him with his Penetrating Fist that is swiftly followed up by several electric spheres that pushes his evil grandfather toward Iron Fist, who utilizes his Volcanic Roar move. The New Avenger surrounds himself in a pink energy pillar with an energy dragon revolving it that launches Heihachi high into the air for Devil Jin to finish off. "The Mishima bloodline…" Devil Jin spirals into the sky and manifest his pitch-black wings, showing off his wicked smile before screaming, "ENDS HERE!", and defeating his grandfather with an explosive Devil Beam that slams him hard into the sandy beach.

BGM End

Jin returns to his normal form exhausted, prompting Iron Fist to come to his assistance. "You alright?" Iron Fist asked, offering his hand.

"Yeah. Thanks." Jin replied, accepting his hand that pulls him back onto his feet. 'But my Devil Gene…I lost control for a moment, but it felt different from normal. How…?' He thought with a frown, sensing some other factor triggered his Devil Gene.

BGM-Project X Zone 2 OST-Because It's the Right Path

With the exception of Captain America's team, the crossover heroes regroup now that Iron Hydra Forces have been dealt with and STRIKE is cleaning up the Zone. "You guys win?" Sonic asked the fighters that defeated Iron King and Heihachi.

"Yep. Thanks to Knuckles's Cross Art." Yang smiled, sharing a fist bump with her red rival.

"So that's what that was. Awesome. Gained the power to harness the earth's energy." Knuckles grinned, loving his new power.

"All thanks to you two bickering like a married couple." Spider-Man teased.

"Yeah right. Only a klutz like you could fall for this meathead." Knuckles snarks back, earning an angry kick to the sand by the eye-twitching Yang.

"You're the buffoon that loves getting tricked all the time! The only interest I have in you is beating you to a pulp!" Yang retorted.

"Yeah?! Try it right now!" Knuckles scowled, quickly clashing fisticuffs with his fellow hothead.

"Stop it, you two! Save your energies for the Iron Hydra Empire." said Captain America, returning to the beach with his group and the rescued STRIKE Agents.

"Cap, you're back. You saved the prisoners." Pit grinned happily, just as Knuckles and Yang stop their fighting.

"I see you cleaned up nicely too. Good job, team." Cap smiles proudly at his fellow heroes for stopping the Hydra invasion.

"It was a bit tough at times. This Iron Hydra Empire won't be easy to beat." X commented.

"An alliance between terrorists from our homeworlds was expected in this situation. We'll dismantle their empire as soon as possible. For now, let's lead you to that recon post. I suspect the Iron Hydra isn't done here in Mistripoor." Cap proclaimed.

"Right! Off to the city!" Ruby happily announced.

"I'm coming along." Heihachi announced, suddenly returning in a suspicious attempt to join STRIKE.

"Heihachi! Didn't Jin bury your ass into the sand?" Naoto snarked.

"I only came to this world to fight strong fighters. My idiot grandson wasn't my top priority. If Jin and I are here, there's also a chance my idiot son is somewhere here too." Heihachi explained himself.

"I am in no rush to meet Jin's Dad if he's anything like you." Sonic sassed.

"Oh, he's worse. Where do you think the boy got his Devil Gene from?" Heihachi quipped. "Regardless, I'm just looking for fun. So, I figure it'd be faster to just follow you and see where the trail leads. Don't worry about me. I'm just doing what I want here." He laughs heartily.

"You are a crazy old man." Knuckles retorted.

"The word 'subtle' isn't in your dictionary, is it?" Weiss snarks at the Mishima elder.

"Well, better to have him with us than not." Iron Fist commented.

"Do whatever you like. Don't let me stop you." Heihachi responded stoically to their criticisms.

"You have any objections, Jin? He's your grandfather." Captain America asked him, planning to support whatever his decision will be.

Jin exchanges a stern glare with his evil grandfather, spending a silent moment to think carefully about the benefits and consequences of his recruitment. "…Let him come." He decided, much to the shock of some of his teammates. "I won't be stupid enough to put our rivalry ahead of what needs to be done first. Once the time comes, I'll kill him myself." He proclaimed sternly as he accepts Heihachi into STRIKE with great reluctance.

"Well said." Heihachi chuckled.

"What's with all this blood and vengeance with these rich families? This is the last time I get involved in family affairs." Spidey joked, finding the Mishimas worse than the Osborns and Schnees combined.

"So, we were going into the city, right? Lead the way, Captain." Heihachi said to the Avenger.

"Alright. Follow me." Captain America announced, leading his newly-evolved team into the heart of Mistripoor.

BGM End

Later in Mistripoor…

The United Heroes made it to the medieval domain of the hopelessly poor here in Mistripoor. Lowtown. As the nation does not allow any criminal extradition within its borders, the impoverished and crime-ridden business capital became home to a sophisticated and powerful criminal underworld. Heihachi is loving the sights. His newfound allies, not so much. They are doing their best to avoid attraction while Captain America leads them to their destination that strangely resembles a barber shop.

"We gettin' haircuts?" Spider-Man joked.

"Yang could really use one." Sonic teased.

"Have you seen Heihachi's?" Yang retorted in annoyance.

"It's perfection. Don't be jealous." Heihachi quipped.

"Follow me." Captain America told the party.

The door opens and the heroes are greeted by what looks to be an ordinary barber. "Have a seat." The Barber gestured. Everyone takes a seat, some making themselves comfortable. As they wait for something to happen, the Barber presses a button hidden underneath the top of a table. One by one, the heroes are dropped into secret tunnels like they're spies being transported to their hidden base. Most of them like Captain America, Knuckles and Weiss maintain a serious face during the transport. Of course, others like Spider-Man perform the exact opposite.

"YAY! A RIDE!" Spidey hollered, treating this like a day at the amusement park.

BGM-Marvel Future Fight OST-Mission Briefing

Didn't take long for the heroes to arrive in the secret SHIELD Recon Post. Organized by a notable SHIELD Agent that greets the guests. "Gentlemen, my name is James Woo, Agent of S.H.I.E.L.D.. Welcome to Mistripoor, the armpit of the unified world." He introduced himself, projecting a hologram of the city-state for the heroes to look at.

"Yeah, we noticed." Blake snarked.

"The place the bad guys go when the Kitchen gets too hot." Iron Fist summarized.

"I told Nick Fury, 'You want to help Mistripoor? Blow it off the map'." Jin said to the SHIELD Agent.

"Be that as it may, up until recently it was a free-for-all. But now? Now we're seeing a turf war between the new Iron Hydra Empire and the ninja warriors of The Hand." Woo responded, displaying footage of the two factions warring with each other.

"I thought this place was strictly ninja territory." Iron Fist remarked.

"It was. Until Hydra started making some big, bold moves. Say hello to the main players…" Woo said, now displaying images and info of the most important characters in this turf war, "Viper, aka Madame Hydra. Her right-hand man, Crossbones. Their newest ally from the Iron Dominion, Regina Ferrum, also known as Iron Queen. Gorgon, the current leader of The Hand. Elektra Natchios, The Hand's master assassin. And Walter Naugus, their powerful troll wizard. We had Agent Carter in the field, undercover. Word is, her cover's blown."

"We'll go right now. We'll extract her." Captain America retorted sternly, as Sharon Carter is his girlfriend.

"IF she's still alive." Heihachi responded with a teasing grin that serves the purpose of irritating the captain.

"Based on her last report, I think she found out something important to both sides." Woo informed them.

"The tablet." Tails realized.

"That's my guess. When you find her, you're gonna have your hands full." Woo claimed.

"Great. Let's go beat some ninjas." Knuckles said whilst smashing his eager fists together.

"You say that with such glee." Pit quipped.

"Hey, I like what I like." Knuckles scoffed with a smirk that is looking forward into pulverizing this turf war.
