Everything in Canterlot had changed in the last 20 years. Creatures from all kinds were now roaming around, not just ponies, all in peace and unification. But a familiar figure in red strolled through, causing many and all to gasp and stare in shock. He stopped and got a long look at a statue of a that showed a very familiar humanoid looking like he was taking a selfie, with the phone in it's hand, and the decapitated head of another humanoid with a very wrinkly chin in the other. He just took the phone out of the statue's hand and looked through the pictures, memories of a past long forgotten.
"Damn. Everything has changed." He spoke before teleporting away.
Inside Canterlot's castle, a new pony sat on the throne, looking almost like Celestia in build and height, complete with a flowing mane & tail as well. But unlike her, she was mostly purple, with a darker mane & tail that had a magenta stripe in both. Sitting next to her was a purple dragon with green scaled running down his back to tail, about as tall as her, but built with a huge top, though small legs.
"Well, what's the problem?" The dragon asked, sounding a bit young, but with a deeper voice.
"Ever since I took Celestia's place, I've been teaching magic." The new princess answered. "But my most Important lesson seems to not be hitting home with my student."
"What do you mean?"
"That I'm glad my royal ambassador and friendship ambassador is here now!"
"Um... your majesty?" A voice spoke, trying to not break into tears. "There's uh... someone familiar here."
"... What's wrong, Gallus?"
"Well... uh..."
The doors busted open with an epic choir with rock & roll music playing. Standing in the doorway was Deadpool, with his cellphone back.
"I'M BACK, BITCHES!!!" He yelled. Gallus, a blue griffin in golden armor, popped his head in, tearing up.
"He's back! My dad's back!!!"
"WHAT!?" The huge dragon yelled.
"Wait... Spike!?" Deadpool asked, appearing next to the dragon. He grabbed the dragon's face, then compared his chest to his own. "Damn! What the fuck were you doing!? You're as built as Arnold Schwarzenegger!" He looked to the princess, who had a bit of a surprised look herself. "And Twilight? You... you look like Celestia... but purple."
"I get that a lot." She answered calmly.
"Are you not seeing this!?" Spike asked in shock. "Deadpool is alive! He's back from the dead!"
"I actually figured something like this would happen." Twilight stood up from her seat and walked out of the throne room to the right, but came back shortly. "Let me guess, you're either a Deadpool from an alternate dimension that just happens to be like ours, but your version of Equestria was destroyed?"
"You'd think that." Deadpool answered, walking around and inspecting her. "But no, I'm his clone that was sent to make sure that the writer would continue writing this fic back when he lived with his dad through that messy divorce those years ago."
"That was my second guess."
"How would you know that?"
"I went back and saw your rotting corpse."
"Ooh! Is it-?"
"Yes, as you wrote before your died, 'Instead of burying my body with sweet-smelling flowers and surrounded by sweat-smelling followers, preserve my body fetal pig style, in a giant mason jar filled with the tear of all the heartbroken private school girls that will miss you, so your body can re-animate and start a zombie apocalypse on March 31st, 2046 at 2:03 PM'."
"Yay! Did you also-?"
"Yes. We got the rock band 'Taranchula' to write and perform your funeral dirge, and played your pre-recorded eulogy on the five boomboxes you had in your disgusting house."
"And my house!? What did-?"
"We burned it to the ground."
"... Oh... I thought you'd turn it into a museum."
"No, but we did take all your weapons, researched them, and upgraded Equestria's defenses."
"Um... am I going crazy, or is that Deadpool?" A new voice asked. Everyone looked to see a unicorn standing in the doorway, looking pink with a mane & tail that looked like the colors of a sun rising or setting.
"Oh! Luster Dawn!" Twilight spoke. "Sorry, but yes, Deadpool, or a different but still the same version, is with us."
"But... how?"
"Cloning." Deadpool answered. "And Oh my god! This is adorable! Twilight is now the new Celestia, and you're the new Twilight!"
"... I... think so?" Luster spoke, though was unsure what he meant. "I mean, I read the stories all about you sir, but the way how you died is all... muddied, to say the least."
"Muddied!?" He looked to Twilight.
"I wasn't there that much." She replied with a shrug. Deadpool took a deep breath.
"Ok, you want to know how I died?"
"Yes, please!" Luster answered.
"Alright... well... it happened..." He took his phone out. "... 20 years ago, starting.... now!"
"Let me get this straight." Deadpool spoke. "You're saying that you went around, acting like Grogar, got the villains back together as a team, and they took away your magic!?"
Standing in the field, surrounded by the X-Force, putting on their gear, was Discord, standing and tapping his paw and claw together nervously.
"I mean... yes?" He replied. "But it was all for a good cause."
"WHAT GOOD CAUSE!?!?!? You Literally f**ked Equestria with this!!!"
"And Discord allow Sombra to smash tree of harmony." Yona replied, putting on her helmet. "Yona would smash Discord for destroying tree!"
"We'll handle with him later!" Light Breeze spoke before getting into his Dreadnaught, turning it on. "EQUESTRIA NEEDS THE X-FORCE NOW THAN EVER."
"Agreed." Summer Flare added, sharpening her sword. "With luck, this'll be over fast." Deapool chugged some whisky from a canteen.
"Just... why on earth did you think this was a good idea?" He asked.
"Why!?" Discord asked. "You abandoned the Taco Squad long ago! I wanted to build a team of villains to reform them!"
"I'm a team player! And we've been getting together every Tuesday, remember!?"
"But I wanted some action! Proper action, not just tacos."
"Blame MrAquino for that!" Deadpool cocked a pistol before holstering it. "And let me guess, Celestia sent you to ask uf just in case her army failed?"
"Uh... yes."
"Damn. Alright... X-Force!" Everyone stood up, all attention onto him. "We head out immediately. If I'm guessing, the new Cyrek is at full power, Chrysalis might look different, and Cozy Glow is more powerful. As we all know, we don't kill kids, so no one better kill Cozy Glow, but feel free to murder the other two. Everyone clear!?"
"YES, SIR!!!" The team answered.
"Alright... let's move out!"
The mane 6 were defeated as young baby dragon, Spike, was dropped off to them. Cyrik, the cyborg version of Tirek, was at full power, standing over everyone and powerful. Chrysalis now adorned green armor on her body, with a yellow hue over her eyes. Cozy Glow was now an Alicorn instead of a pegasus.
"Turns out the magic of friendship was your true weakness." Cyrik mocked as an energy beam built in his chest, with Chrysaliss and Cozy Glow's horns glowing. "A fitting end to your pathetic story."
"No matter what, we face it together!" Rainbow Dash spoke as they all huddled together. Everything seemed to went slow as all 3 villains fired their magic at the group. And then... white...
"Is it over? Can I open my eyes now?" Spike asked. The group opened their eyes to see a towering mech standing over them.
"DAMAGE TAKEN. STILL FUNCTIONAL"
"Wait, you can't be-" Twilight spoke before seeing Deadpool and the X-Force arrive, running to and landing in front of them.
"Better look away, professor." Gallus spoke, putting a clip into an M4, "This is gonna be pretty nasty."
"Oh great!" Cozy Glow spoke. "These guys!?"
"Yes, Cozy Glow." Deadpool spoke. "You might be powerful now, but there's one thing you lack!"
"Ugh, let me guess, 'Friendship'?"
"... No. Firepower." He pulled a gun out and fired at Cozy Glow. The filly didn't have much time as something silent was fired, and she felt a prick between her eyes. She pulled out what looked like a needle with some feathers at the end.
"What was that!? Did you... just... tried to..." Her vision went blurry before she fell to the floor, snoring loudly.
"Heh, powerful alicorn filly can't defeat an elephant tranquilizer dart."
"Bah! She means nothing to us!" Chrysalis hissed. "Cyrek?"
"With pleasure." The centaur cyborg stood proudly, loud beeping everywhere as his cybernetic eye glowed red, and various weapons started to pop out, aiming at the students.
"Spread out!" Selina yelled, jumping and rolling out of the way. The others followed as Cyrek fired a barrage of missiles and lasers at them all, barely hitting them, only causing some to fall to the floor from the impact of the explosion. Deadpool charged ahead, but was tackled by Chrysalis, taking on his form. The two rolled across the floor, landing next to Gallus. He picked up his M4 and aimed at them both. Both Deadpools stopped.
"Don't shoot!" The one on the left spoke. "I'm the real Deadpool!"
"No! I'm the real Deadpool!" The other added.
"... Crap. Sorry about this." He aimed at the left Deadpool and fired everything at him. That Deadpool fell to the floor, a pool of blood forming onto the floor.
"Yes!" The right Deadpool cheered. "I knew I could-" Gallus quickly turned and fired at that other Deadpool, causing him to fall down to the floor, making another puddle of blood to the floor... but this one's was green. In a burst of green flame, the Deadpool turned into Chrysalis, gurgling and bleeding with her own blood. The left Deadpool got up, coughing a bit.
"What was that for!?" He asked.
"Sorry, but only one of you can heal." Gallus answered, looking to Chrysalis. "Plus, I don't think Changelings have red blood, so either way, you were both gonna be shot."
"Hmm... fair enough... but I don't know what Fluffle Puff is gonna feel about this." As he said that, the familiar pink fluff of pony showed up, gasping at the scene, rushing over to Chrysalis and picking her head up, tearing up. She turned to the two, fury in her eyes. Without a word, Deadpool and Gallus pointed at Cyrek, who was smacking everyone to the side. Fluffle Puff began to shake violently before rushing to Cyrek at speeds so fast, the floor was on fire. The pony let out a loud scream, that it was actually heard in locations across the multiverse.
Somewhere in Maretropilis, a young man with twin lightning guns sat and patted the head of a Twilight-looking pony, before stopping and hearing the loud scream, with the pony looking up as well.
"What was that?" She asked.
"I have no idea." The human answered.
"And don't ask us!" A pair of Ghouls from Tokyo Ghoul added, popping their heads out from the side.
A blue, dog headed humanoid overlooking an underground training facility ear's started to flinch as he heard the screaming.
"... Something tells me that Deadpool is behind this."
An actual Warhammer 40k Space Marine and a Halo Spartan polished their weapons before stopping and heard the screaming.
"What was that, brother?" The Space Marine asked.
"Either we've gone mad, or that's a daemon or something similar." The Spartan answered.
A trio of swordsmen from the worst anime not based on an actual video game polished their swords around a campfire before hearing the scream.
"... Should we be concerned?" The woman asked.
"... Nah." The other 2 guys answered.
Princess Twilight, Luster Dawn, Gallus, and Deadpool stopped as they heard the scream.
"Yep. That's how her scream went." Deadpool spoke. "But as I was saying..."
Fluffle Puff tackled Cyrek, who didn't have any time to respond before receiving multiple punches to the face, all rapidly and with so much force, pieces began to fall off. It didn't take long before Cyrek's head was detached from the body, and for the head to become nothing more but a paste of blood, gore, and wires. The body only twitched before falling down, deactivating, and Fluffle puff stood there, snarling hard, before falling to the floor, becoming unconscious.
"... So... we did it?" Roscoe asked.
"Yep. We did." Strongheart answered. "All 3 villains are defeated."
"You killed them all!" Applejack yelled.
"Nu-uh!" Deadpool retorted. "We only killed one! Cozy Glow is just sleeping right now, and Fluffle Puff just stopped Tirek from becoming an even more powerful cyborg. And you're welcome with us saving you from Discord's dumbass plan to get all the villains together to reform them in his own unique way, completely forgetting that Tirek betrayed him, and all these baddies are just gonna backstab each other as soon as they were done. For now though... everyone! Victory dance!"
Music played as the place became a disco floor, and the X-Force performed Jimmy T's Dance, the Feline Fever.
"But that doesn't explain how you died." Luster Dawn spoke. "From the sounds of it, you were all successful... despite not really doing much."
"Eh, it happens with a lazy writer." Deadpool replied. "And I was gonna get to that, actually. But first, folks, if you've been following me, now you've missed your chance for a crossover with me! Because in the next part of this 3 parter finale, all the displaced heroes together as one against a common enemy, one that many of you should've seen coming back in 2016."
"... Who's that?" Deadpool just sighed.
"Thanos."
