Earth, 2099...
Sloan looked at the monitor with Serena. "Interesting... Atrocity's mere presence in the Gateway room is causing the chronal energy readings to spike more than usual. Discord did his job well. This means that very soon, we can finally create the empire we so desired across time and now through dimensions." he boasted, looking at the wires connected to the large symbiote clone.
"How can we be sure it's not haywire?" Patel asked.
Sloan glanced at the monitor once more and placed his hands behind his back. "His unique powers may be haywire right now. But very soon we will be able to harness his abilities and use them to our advantage. I am already detecting a large number of rifts scattered across Equestria, and the number continues to grow even as we speak. But I am sure the heroes of that world are aware of what's happening and are planning to stop us right now."
Doc Ock 2099 faced the portal. "I will handle them. I have a bone to pick with them anyhow. My robots will distract them while you continue to harness the chronal energy from Atrocity. I myself shall head to their hometown, Ponyville, while my robots divide with me and to that other town they have protected, called Canterlot."
Sloan nodded, "Go ahead. I will open the portal for you and your army first, then I will summon your robots to Canterlot. I will stay here and attend to Atrocity. Even if someone were to show up, it will be too late to stop the collapse of time."
Doc Ock 2099 smirked, gazing at the portal, her robots hovering into the room right before she stepped forward. Once they cleared, Walker summoned more robots and sent them to Canterlot, where the remainder of the robots will be warped to. "The Spider-Men won't be able to stop this. Even if they destroy Atrocity, the timeline is starting to collapse in on itself." he chuckled.
Canterlot, Now...
The Spider-Mobile drifted to a halt, seeing more rifts block its path. Anti-Venom roared, lashing his own tendrils at the attacking tentacles standing in their way. Once they cleared, the Spiders and symbiote jumped out of the vehicle, Spider-Mane hovering over the others at their pace with his jet thrusters.
They approached the castle again, but the noticed that more tears in the fabric of time and space began to open. At this point, Peter and Ben's Spider-Sense began to tingle, warning them of the dangers they were already aware of. 'Alright, Spider-Sense. I get it. Last thing I need right now is a migrane to slow me down.' he scolded his brain, which continued to ring.
"It's getting worse. We're running out of time." Eddie observed.
"What's left of it anyhow." Miguel corrected. "Atrocity's mere shocking existence is somehow doing this. How?" he wondered, slamming his hooves on the ground in frustration. "This is getting out of hand, jam it! How did Warren even create something with that much power?!"
"I'm not sure. He just suddenly did all this without warning." Peter explained the best he could. "We gotta get Jackal and bring him back with us so we won't have to worry about him later on."
Eddie and First Spider hopped put of the way of more rifts opening in front of them in time, seeing Atrocity's tentacles appear out of thin air once again. Kaine shot them with a web-bola, forcing them to retreat into the portal, closing it. Anti-Venom lashed his own tendrils at them, doing the same thing as well.
The Spiders slammed the doors open, seeing the future ponies already grouped at the castle with the princesses. Peter sighed in relief. "Alright. Good to see you all made it fine."
"It wasn't easy." Future Sweetie said. "These portals are getting out of hoof."
Future Rainbow smirked, "But I showed each of them what for when they did show up!" she announced.
"No you didn't. You screamed everytime one of 'em showed up." Future Applejack corrected with a smirk.
"Wha- no, I didn't!" Future Rainbow insisted.
Future Trixie rolled her eyes, "Can we please cut this out?"
"She's right. Where's Jackal? We need to take him back now." Scarlet Spider said.
Celestia and Luna nodded, handing him Jackal's unconscious body. "Heh. Look at that. He's still tuckered out. Alright, now let's get back." he declared.
As Ben said this, another vortex opened up in the castle. But instead of Atrocity trying to attack them, they were robots coming in to draw them out. "Ock..." hissed Spider-Mane 2099, "She's trying to shocking distract us right now!"
Pinkamena unsheathed her sword and swiped upward at a robot, slicing its head off with ease. "You five go ahead! We'll handle these... Mechanical creatures!" she ordered.
"C'mon, kid. We gotta get to 2099 as soon as possible!" Kaine said to his brothers. "They can take care of themselves!" he was the first to hop back in the Spider-Mobile.
Spider-Mane turned around and watched his friends fight off the oncoming robot army, then faced First Spider and the others already waiting for him. With a sigh, he hopped back into the driver's seat and drove off to find a possible rift to go back to Earth to. "Let's do this." he said with determination.
Back in the castle, the future ponies and the princesses were holding off the robots. "So, what does the future hold for us?" asked Luna, curious about their presence.
"I'd rather not say." Future Sweetie responded. "Time travel is a complex, fragile topic. It's a miracle we even came back to this past timeline instead of our own."
"I agree. It would be best if we not learn of what shall happen." Celestia said in response, "It appears time is already falling apart at the seams anyway."
"Yeah... You're better off not knowing." Pinkamena agreed.
Future Rainbow grounded her hooves into a robot's head, tearing it apart upon contact. Future Trixie gritted her teeth, focusing her energy on her horn as she performed a small shockwave spell that tore apart a few more robots in their way. Future Sweetie, Applejack and Pinkamena attacked the same robot together while Celestia and Luna fought off on their own area.
"Let's hope they get rid of the source of these robots." sighed Future Sweetie. "I don't know how long we can hold ourselves before they overwhelm us."
"Pfft. We totally got this." Rainbow said, before she buckled down in pain, "Agh!"
Future Sweetie put a hoof around the pegasus, "Rainbow! What happened?"
"Heh. I'm fine, kid." Future Rainbow assured. "Just a cramp is all."
Trixie rolled her eyes and rubbed her head, "Sure. If you're not up for fighting, no need to put on a tough act. Even Trixie admits she's feeling a little off herself."
Future Applejack tilted her head, "Ah thought that was just me."
Pinkamena scowled once she heard that, "Something is wrong... Unfortunately, now's not the time or place. If things get dire, the three of you should retreat."
"No way! We got... Ack!" Future Rainbow coughed, seeing blood on the floor, "...Oh crap."
Ponyville...
"Thank you." said Twilight, placing the crown over head. The Elements of Harmony were placed on each wielder. Each of them had their cutie mark shown on them, and all of them except Twilight's Element of Magic were worn as necklaces while the alicorn's was a crown. "We should stick close together just in case something happens."
"I agree with Twilight over here." Black Cat said.
The alicorn gritted her teeth, "Nopony asked for your opinion."
Felicia shrugged with a smile, "I assume I can't get on your good side, hm? Can't blame a lady for trying."
Sunset shook her head, "Well, what are we waiting for exactly?" she wondered.
"Wait! Where's Peter and the others?" Spike asked. "Didn't they say that they were coming back here?"
"They all left once they got here to get Brock. Peter mentioned he's on his way to 2099 to stop Sloan once and for all." Twilight explained to thr dragon.
A portal opened up on front of them and Twilight and Sunset shot at them, forcing Atrocity's tentacles to retreat and close the rifts almost immediately. "This whole portal thing is really starting to get on my nerves." Rainbow huffed.
"You're tellin' me." Applejack agreed.
Suddenly, a group of robots descended from another portal, as well as a pony. "Oh great... Not her." Rainbow moaned.
"Is that...?" Fluttershy began to ask.
Pinkie nodded, "It is!"
Doc Ock 2099 landed on the ground with her robots. "I have a score to settle with you pathetic ponies. My robots have been upgraded to take down each and every single one of you. Surrender and I may spare you all in our takeover."
"Pathetic?" asked Rainbow, "Last I checked, we kicked your sorry flank so hard you ran away!"
Black Cat was the first to speak, "How about no? I didn't come here just to have this world become a robotic empire. I like living thank you very much."
Twilight turned to face the children, "Mayday, Applebloom, Sweetie Belle, Scootaloo. Get to Sweet Apple Acres. We don't want any of you getting hurt in what's about to happen next. Fluttershy! Can you get them to safety?"
"Okay, mommy!" Mayday answered. Fluttershy turned around and guided the fillies out of the way while the others kept Ock distracted by talking some more.
Serena hissed, "Very well. If you won't surrender, then I have no choice in this matter. Robots..." she began, the ponies beginning to get ready for the biggest battle they faced in a while, "Attack!"
"Oh of course..." Pinkie sighed.
Rainbow smirked, "We can take them on again!"
Twilight nodded, "Just keep an eye out for any more rifts. Last thing we need is those Atrocity things to catch us off guard."
Felicia rolled her eyes, "I'm getting sick of time-travel..."
Canterlot...
The Spiders faced the nearest rift. Spider-Mane spoke, "There it is. After this, there's no turning back from here. Ben, you got Jackal? We're webbing him up in the building." he asked his clone brother. Scarlet Spider nodded, Warren's body lying on his back. "Then let's head in. Back to the future!"
First Spider groaned, "Was that a reference? Typical..."
"Let's just shocking jump..." Spider-Mane 2099 exhaled sharply.
"Very well..." Anti-Venom growled. "For time itself..."
The five Spiders jumped into the portal, where they seeked to end this once and for all. Spider-Mane was the last to jump, 'I'll come back... And I promise... The others will go home.' he thought, before hovering into the portal.
Earth, 2099...
"It's almost ready..." Sloan chuckled. "In a few minutes, the portal shall be ready and then I can begin bringing Alchemax back and reshaping time itself in my image."
"Not so fast, Sloan!"
Walker turned his head, "Who dares!? Spider-Man!?"
"Were you expecting Howard the Duck?!"
The Spiders revealed themselves, jumping out of the portal and back in their human forms. Peter's armor looked the same, but fit for his original body. "It's shocking over, Sloan! Turn this Gatway off now!" Spider-Man 2099 ordered. "It's five Spiders against you now!" he added with determination in his voice. As he said this, Ben webbed Jackal's body to the wall.
Sloan laughed, "You're not in a position to demand anything, Spider-Man. You are aware that I have Atrocity and time itself bending to my whim, correct?" he pointed to the large symbiote monster standing behind them.
"...We're aware." Peter commented.
"Your time has come, Sloan!" Anti-Venom roared, lashing a tentacle in Sloan's way. He leaped there and uppercutted Sloan so hard that he was knocked unconscious. Eddie them webbed up his body next to Warren's. "Oh, I've waited to do that..." he hissed.
"About time someone shocking shut him up!" Miguel yelled.
First Spider pointed behind them, "We still have this son of a bitch to take care of. And that probably means Ock is back in Equestria... The girls can finish her again."
Atrocity roared loudly, making Scarlet Spider gulp. "This thing can control time? We're in for something big."
Spider-Man nodded, "Oh, you have no idea. Time and space are in our hands... Something tells me we're doomed." he gulped, watching Atrocity charge after the five for the final battle.
