"Thanks, Slade." Oliver said as Slade accompanied the group down the woods.
"Not a problem, kid." Slade assured.
"What brings you here anyway?" Oliver asked and Slade stopped with a haunted look in his eye, which worried Oliver, since last time he saw that look was when…
"I found him, Oliver." Slade said and Oliver's blood ran cold, realizing what had happened. "He's working with that monster."
"Slade…" Oliver trailed off, putting a hand on Slade's shoulder, trying to comfort him, while Sara, Barry and Caitlin, for all their reservations against Slade, felt sympathies for him, knowing from Oliver what had happened to Joe.
"Who is he talking about?" Wanda asked.
"My son. He's working with Apocalypse." Slade said.
"Why would your son work with someone like Apocalypse?" Steve asked, speaking for everyone else, who was in the dark.
"It's a long story. Short version, Joe once saw his father kill someone, when he was a child and that, in addition to his father's actions as Deathstroke, pushed him down a dark path. But it's not the Mirakuru with him, but anger and resentment." Sara summed up and everyone could feel only sympathies for Slade.
"I'm sorry." Oliver said.
"What are you going to do to your son, once you get him?" Logan asked.
"I don't know… I'm not sure I can reason with him anymore… at least right now… but I'm going to make sure he's not going to hurt anyone, ever again. I won't kill him but I'll do whatever I must to stop him." Slade said.
Logan sniffed into the air and growled. "Get ready as he pulled out his claws. We're about to have company."
Steve pulled out goggles and spotted mercenaries and a small group of mutants approaching them, with some of them leaping great distances like frogs to get to them.
"And a lot of them." Steve said, when suddenly, some beams of light started to fly towards them and Barry grabbed everyone and got them to safety to avoid the beams, before Oliver, Slade, Clint, Bucky and Natasha opened fire, shooting some of them down. Wanda lifted the mutants into the air and slammed them to the ground, knocking them out, while Barry sped at the small group, taking them out but suddenly, the leaves started to fly around and towards them, grazing them like if they had razor edges but Wanda evaporated the leaves before they found the mutant manipulating the leaves with gestures of his hands.
Oliver and Clint fired arrows but the mutant sliced the arrows in half with the razor leaves and used them to deflect the shots from Natasha and Bucky before Barry created cyclones, blowing the leaves away and giving Steve an opening as he threw his shield, taking the mutant out of the fight before the shield bounced back to Steve.
"Well, that would do it. Let's just hope that's…" Steve trailed off, when they all heard something and looked up to see something flying towards them, shining in purple light as their eyes widened. "Incoming!"
Wanda immediately formed a shield around everyone, trying to block the volley of blasts falling down upon them but struggled. "I can't hold it for long!"
"On three, let go! One… two… three!" Barry ordered and the moment Wanda let go, Barry grabbed everyone and sped them to safety from the volley of blasts as it bombarded the entire forest.
"They have the Flash on their side." The mutant noted as he stopped bombarding the forest with energy blasts from his hands.
"Doesn't matter. No one gets past us. No one!" Joe ordered.
They got past the barrage bombarding the area as they were outside the facility before they saw the winged man again in the distance, while Logan took a closer look with his goggles.
"Warren?" Logan asked, shocked.
"What?" Everyone turned to him in surprise.
"Wasn't he scouting Apocalypse's movements for you?" Steve asked.
"He was… I guess Apocalypse got him and did something to him." Logan said, noticing that Warren's skin was blue and his wings were made of metal instead of feather.
"We can figure this out later. Right now, we need to get into the facility." Oliver said.
"Uh, I think we've got bigger concerns." Clint said, giving them the goggles as they saw the army guarding the area, among which were some behemoths that could compare to Hulk in size and muscles.
"If Tony were here, he'd have enough tech to take them out." Steve said.
"Pity we couldn't bring Hulk but I guess subtlety is overrated sometimes." Natasha quipped.
"Don't worry, fellas, these folks are in for one hell of a surprise." Mack assured over the comms, when suddenly, they felt tremors shaking the area as the mutants and soldiers were sent flying back by a young brunette girl in standard S.H.I.E.L.D. uniform and next to her were a blonde woman, with some batons as her weapons and a middle-aged man with short haircut and pulling out a gun and Spider-Man, who webbed the soldiers as he swung around and Rhodey in his War Machine suit, shooting down everyone getting in his way.
"Don't worry, Captain, we'll keep the guards occupied. Get in and shut the place down." Rhodey said.
"Got it. Be careful, Rhodey." Steve said as they approached the docking area but stopped, when they noticed several laser gunsights aiming at them.
"I know how fast you are, Flash, but tell me, are you faster than light?" Joe gloated, while some of his men were holding in their hands some hi-tech weapons that Barry recognized, similar to the Plunder's weapon. While he was sure he could dodge most of the shots, there was no way he could protect everyone else.
Improvising, Oliver fired an explosive arrow into the column supporting the bridge above them as it collapsed as most of Joe's men fell down but enough of them had managed to avoid as they opened fire, when Barry tried to help everyone avoid the shots but some of them grazed him as he phased through a wall for the shots to hit it. Clint and Oliver shot the weapons off the soldiers, while Bucky and Natasha took them out as they fired back.
Suddenly, an RPG was flying towards Joe's men as the explosion scattered them around as a man wearing a long black leather jacket with a pair of machine guns with a grenade launchers attached to it, roared, opening fire at the remaining soldiers as blood spattered.
"Well, that's a surprise." Slade smirked.
Frank Castle, also known as the Punisher, reloaded his machine guns as he approached the group. "Heard this asshole was kidnapping people and building an army. No way in Hell I'm gonna miss that." He glanced at the facility in front of them. "Go, we'll handle this."
Joe was running down the catwalk as Slade looked up, narrowing his eye before he pulled out a grapnel and ascended above, chasing Joe down.
As Frank, Slade, Spider-Man, Rhodey and Mack's team were keeping the guards outside busy, the rest group entered deep into the facility, trying to find a way to shut down Apocalypse's operation.
As they entered the facility, they had to fight through more of Apocalypse's soldiers and mutants guarding it but at this point, they worked together like a well-oiled machine, so it was no problem for them to take them out.
The guards were at the gate, preparing their weapons and powers, when the door shattered like ice and a blizzard followed, freezing them before red wave of energy shattered the guards to pieces.
"Nice." Both Steve and Barry said in unison, smiling at Caitlin and Wanda.
More mutants appeared, some of them lunging at the group like animals but Logan lunged at them too, slicing them down before a man covered in metal showed up and picked a giant piece of machinery, slamming the other mutants and started to beat up the guards, who were unable to penetrate his metal skin before Vibe and Jean jumped out from the breach, joining the fray and helping the metal man take them all out as Vibe blasted them down and Jean used her telekinesis to knock them out.
"What are you doing here?" Logan laughed.
"Didn't think you could have all the fun for yourself, did you, Logan?" Colossus smirked.
"Besides, if there's a powerful telepath or anything else here, you know you need my help." Jean said.
"Do you think you can keep them busy?" Steve asked as Colossus chuckled.
"Kapitan Rogers, it will be my great pleasure." Colossus said before he rushed at Apocalypse's men, slamming one of them to the wall, knocking him out and punching another one in the face, sending him sliding down the floor. As powerful as the mutants were, they were no match for Colossus's brute strength.
Joe kept running, while Slade chased him down the maze of catwalks and slicing down and shooting down anyone getting in his way, mutant or human. Even though he did not have Mirakuru in him anymore, the sheer determination and willpower were giving him a clear edge. Slade cut through the spikes one of the mutants threw at him as they were forming in his hands and impaled him with his sword and used him as a shield, to protect himself from energy blasts from another mutant before Slade pulled out his gun and shot the mutant in the head. Slade rolled to avoid the acidic spits from a mutant, who was crawling on the wall above him as the mutant above dodged the shots from Slade's gun but then, he was ensnared in web as Spider-Man web-slinged around, firing web bullets to take out Apocalypse's mutants.
"And here comes the web rain!" Spider-Man quipped.
Slade shook his head at the young boy making quips, only happy that Oliver wasn't like that, when they first met. More mutants and soldiers appeared but a blonde woman in purple suit with metallic batons jumped down from above, catching them off-guard, taking them out, while a Quinjet flew around, piloted by a man in his late 30s with unshaved face and talking with a British accent.
"Didn't think we'd let you have all the fun, did you?" Hunter quipped over the comms.
Bobbi jumped back before the floor under her feet would melt and threw her battle stave at the mutant causing it, knocking him out before the stave flew back to her as Slade cornered Joe to an empty helipad.
In the courtyard, Frank and other S.H.I.E.L.D. agents kept taking out Apocalypse's men before Frank ran out of ammo and pulled out a knife and roared. Frank dodged, when one of the mutants unleashed a torrent of fire at him and Frank rushed at him, slitting his throat and knocking him down before Frank stomped on his chest, crushing his ribcage. Frank picked one of the metallic spikes protruding from the ground and picked it up, using it as a weapon as he impaled a nearby mutant rushing at him with some electric whips before he took cover from energy blasts of another mutant and pulled out his gun, shooting the mutant down.
Thunder roared in the sky as Thor tossed Stormbreaker like a boomerang, cutting down more of the soldiers and then a barrage of lightning bombarded the courtyard, taking out the rest of Apocalypse's forces. For a moment, they thought they had taken control of the outside before Thor was suddenly grazed by something sharp and metallic as a blonde man in blue armor and skin with metallic wings flew around before flying towards Thor, ignoring the lightning Thor threw at him as they exchanged blows.
Steve threw his shield as it bounced off the guards, knocking them down, while Oliver and Clint kept shooting arrows and Wanda tossed the guards around as Cisco fired his vibe blasts, taking the guards out. Sara used her batons to block as one of the mutants with some blades coming from his arms attacked her and dodged and jumped to avoid getting cut before she hit the mutant in the leg, causing for him to kneel and Natasha finished him off by shooting him in the head and Caitlin froze some of them before Steve again threw his shield, shattering them. Logan ignored getting burned by the fire as he impaled another mutant with his claws, while the pyrokinetic mutant tried to incinerate him but Logan healed as fast as he could before Logan finished him off and the mutant gulped, blood filling his mouth before he died.
They approached a nearby computer as Oliver took a look and they saw the footage, which disgusted them. On it, they saw people being kidnapped and experimented on by Thawne and Mr. Sinister as everyone, especially Barry, Caitlin, Cisco, Wanda, Steve and Bucky glared and seethed with disgust.
"I knew he was a monster but this…" Barry seethed and what horrified them was that one of the people were in a tube, screaming and banging on the glass desperately before she melted into some kind of goo.
"My God…" Sara whispered.
"Her cells refused to adapt to X-gene. How unfortunate. I think we need to infuse dark matter." Thawne said.
"They're experimenting on people. Turning them into metas and mutants to bolster Apocalypse's army." Clint realized.
"All the more reason to shut this place down." Steve said.
"They're not only using people but clones using the DNA of mutants they captured back on Genosha, experimenting on them." Caitlin said, reading the information.
"How do we shut it down?" Oliver asked.
"Alright, let's see…" Cisco quickly went over the blueprints on the computer. "Alright, if we overload the fusion core and take out the engineering hub, it should stop the processing." He went over the footage. "There are still survivors. Prisoners on which they're doing experiments. Most likely people they abducted back in the city."
Archangel used his wings as a shield as it absorbed the lightning Thor threw at him before he charged his wings with it and threw his metallic feathers at Thor, grazing him thanks to them being charged by Thor's powers but Thor endured the pain before he flew at Archangel and punched him, sending him flying high into the air until Archangel vanished in the clouds. Thor waited for Archangel to counterattack but to his surprise, Archangel just flew away into the distance. Thor was about to give chase, when Archangel teleported in some kind of a shimmer, vanishing as Thor stopped, realizing that Apocalypse must have ordered him to fall back.
Slade and Joe fenced with their swords before Slade shoved Joe back, pinning him to a tower.
"You're not holding back anymore. Good." Joe smirked.
"I don't want to kill you, but I will stop you." Slade vowed as he attempted to cut into Joe's leg but Joe kicked Slade as he staggered back and Slade barely raised his sword to block as their blades crossed again.
"Do you know what's behind those comas?" Jean asked.
Cisco went over the computer until they found a footage of a purple-haired woman strapped to some apparatus with a helmet on her head, similar to Cerebro and screaming in pain.
"Psylocke…" Logan said.
"Looks like she's unwillingly become his tool too." Wanda noted.
"Alright, let's split into groups. One will stop the processing and another one will take care of the prisoners. Another one will free Psylocke." Steve ordered.
"Oh, great. You're gonna have all the fun in the world, right?"
They turned to face a man in red spandex with black spots on his eyes as the X-Men groaned.
"Great, what are you doing here?" Logan rolled his eyes.
"Oh, don't tell me you're pissed because I was using your face as a mask in my first film, Jackman." Deadpool quipped before turning his eyes on the rest. "So, another Arrowverse/MCU/X-Men crossover, huh? Guess Aragorn, Stand and Bl4ckHunter got more ideas roaming around their minds, I'm surprised there's no blonde quippy girl or a broody tall guy in black coat staking vampires, but though, that would be even a bigger crossover than expected. Should we call Blade?"
"You know this guy?" Steve asked, turning to Logan.
"Oh, great, it's the first Human Torch, but at least he was better than Killmonger." Deadpool said, turning to Steve. "And to answer your question, Mr. Tall and Blue gave me an offer to join his godly crusade or whatever and at least it's not as stupid as him building a giant pyramid, when fighting McAvoy and Fassbander before the whitey decided to experiment on me, when I told him where to shove his plan. Thank you for freeing me, BTW, I just hope Marvel is not gonna fuck up my third film."
"What is Apocalypse planning?" Oliver asked.
"Uh, let me think about it, uh, no spoilers, since that would end this story too quickly, so… not gonna tell you!" Deadpool quipped.
"But—"
"See ya, wouldn't wanna be ya!" Deadpool said before pressing a device on his belt as he teleported himself as everyone stared, wondering what the hell just happened.
"I hate this guy." Logan muttered in annoyance, shaking his head.
"What was that?" Barry asked.
"Don't ask." Jean said, equally annoyed as Logan.
Slade and Joe kept clashing with their swords as sparks flied until Joe disarmed Slade of his sword and was about to finish him off but Slade grabbed Joe by his arm, knocking him down. Joe blocked before Slade could punch him in the face and kicked him back. Joe roared, rushing at Slade but Slade sidestepped him and slammed him to the ground before Slade punched him, knocking him out.
"Sorry, kid. I tried to help you. I tried to reach you… but you've left me no choice." Slade said.
Oliver, Clint and Bucky shot down the guards, while Wanda broke the locks in the prison area, freeing the kidnapped civilians.
"Come on, let's get you of here, come on, move, move!" Oliver ordered before tapping his comms. "Blink, prepare for evac."
A portal opened a moment later as the civilians rushed into it.
Psylocke came to, when she heard noises and the door burst open.
A mutant unleashed a sonic scream, similar to Dinah's but they dodged before it would blast them as Steve threw his shield, knocking the mutant out and they made their way into the chamber, where Psylocke was and freed her.
"Thank you…" Psylocke whispered.
"I see that the people are waking up from their comas. With them awake, the military and other agencies should be able to lead their forces into repelling Apocalypse's army and forcing them out of New York." Xavier said.
"Are all the prisoners freed?" Steve called out.
"Everyone's accounted for, Cap." Cisco said.
"Alright, then. Let's head back and blow this place to bits." Oliver said.
They all retreated through breaches with the freed prisoners, when Thor summoned lightning from above, blasting the facility into kingdom come.
Hope you liked Frank showing up too, since, come on, how could I not put him here? Also, putting in Rhodey, Spider-Man, Daisy, Bobbi and Hunter was fun too. And Deadpool is always tricky to write, so I hope I did him good here, since I couldn't resist a Deadpool cameo.
I know, Psylocke was in X-Men: Apocalypse and should be older but frankly, that film was so much trash that it doesn't exist to me and nerfed Apocalypse, who wasn't even comic book accurate.
So, what do you guys think?
Please review and let me know if you have been enjoying this and want for me to continue.
