Today was the day it's supposed to happen. The team has been working nonstop to save Iris and stop Savitar and find the power source for the bazooka and they were able to find one.

The three boys go to ARGUS advanced research group where they find Lyla.

"Gentlemen." Lyla greets them.

"It's a wee bit chilly." Cisco comments on the weather. "Can we head inside?" He asks.

"Every square inch of that building is bugged. Figured it was better if we talked out here." Lyla explains.

"Okay. I love the breeze." Cisco rephrased.

"I got your message, Peter. But I need you to explain exactly what it is that you need." Lyla tells him.

"Okay, there's a evil speedster on the loose who plans on making himself a god and we have built a device to stop him. Except to turn it on, we need something powerful enough to do so." Peter explains the recapped version.

"Okay." Lyla says, as she's following.

"So, I tasked our satellite to look for anything that might have our specific power requirements, and we found something that has exactly what we need. And it's in that building." Cisco explains to her.

"I really don't think you should be spying on me, Cisco." Lyla states.

"Is it spying if we're friends?" Cisco asks.

"Look, we know you have something, right?" Barry asks.

"It's a piece of Dominators' technology. We got it from the stashed ship in Central City. Except you can't have it." Lyla breaks to them.

"Lyla, we searched everywhere. This tech is the only think that we can use." Cisco tells her.

"I can't do it." Lyla explains.

"Is this because of baby Sara?" Barry wonders, remembering what he did in Flashpoint.

"I'll admit, it's been hard not to wonder to have a daughter instead of a son, but this is less about what happened than why it happened." Lyla explains.

"I made a mistake." Barry admits.

"Exactly my concern." Lyla replies. "This is the kind of tech that wars are fought over. If something happens and it gets into the wrong hands, millions could die." She says before she's called away.

"That's exactly what's going to happen if we don't stop the God of Speed." Peter tells her as she walks away.

"I'm sorry, Peter. I can't help you this time. You'll have to find another way." Lyla tells him and leaves.

-

The three return to Star labs and Barry comes with the idea to steal the device if Lyla won't let them just have it.

"We got a few problems." Peter says and pulls up the technology of the base.

"What's that?" HR asks.

"That is a metahuman power dampener. Speedsters aren't going to get in. Nobody with powers." Peter breaks to him.

"What about you? Can't your powers work?" Joe asks Peter.

"Yeah, me and Miles will be able to." Peter admits, not liking the idea of him stealing something. "Before anyone asks me to do something I don't wanna do, this place is more secure than the pentagon. I should know, I've visited both."

"Why did you go to the pentagon?" Miles asks him.

"That is a long story that involves a man with a skull mask and a sword." Peter explains.

"Okay, this is what we're dealing with; surveillance cameras. Eye scans. Palm prints. Heat sensors. Laser sensors. And that's just the first floor." Cisco lists down to them.

"Yeah, I won't be able to do this alone." Peter tells them right off the bat.

"So, you're saying this is the the most fortified structure in the history of fortified structures, only Peter and Miles will be the only ones able to go in, and we have less than 14 hours." Joe lists to them their problems.

"And we don't have any master thieves." May states.

"No, actually we do." Barry says and it takes Peter a minute to see what he's saying.

"No! Not him!" Peter states, knowing exactly who he's thinking about.

-

Barry was thinking exactly who Peter was thinking about as he ran back in time to the Legends first year and recruited Leonard Snart.

"Yeah, I'm not teaming up with this maniac." Peter informs Barry.

"I'll be down in the lab, getting everything ready. You all have a lot to discuss." Snart says and leaves them.

"The Flash has officially lost his mind. You want Spider-Man and Captain Cold to team up to break into ARGUS, a secret government branch, and steal an alien power source that we fought with my doppelgänger to stop a God of Speed. Sounds like the craziest Fan Fiction ever written." Peter states.

"Look, Peter, he's a master thief exactly what we need and is able to think of solutions just as fast as you. This could be the only way to get the power source." Barry explains to Peter.

"If this backfires on us, I will web you and Savitar to the wall." Peter warns him. "So what's the plan?"

-

"My guess is the power source is most likely here. Because it's the deepest part of the facility, and if it's as valuable as you say it is, then the deepest recesses of any facility are usually the most secure." Snart tells them looking over the blueprints of the building Cisco found.

"You have any idea what else might be waiting for us in there?" Barry asks Peter.

"Could be anything." Peter replies.

"It doesn't matter. There are only four rules you need to remember to every heist. Make the plan, execute the plan, expect the plan to go off the rails...throw away the plan." Snart lists off to Peter. "Follow my lead and you'll be fine."

"Stab me in the back, I'll stab you back." Peter warns him.

"Looks like Spidey's grown up. Okay, that's acceptable. The last I saw you, I did kidnap you and almost froze your hands off." Snart remembers.

"Just out of curiosity, you have a plan for getting in there, right?" Joe asks.

"I was able to get in contact with my doppelgänger from Earth-38, said he couldn't help because of some invasion. So, he gave me something that I'll be able to use." Peter promises them.

"Okay, Joe. I need you to take Iris some place far away from here. From me." Barry tells Joe. "If I know, Savitar will know."

"We'll keep her safe, don't worry." Joe promises and they leave.

Peter watches as Barry and Iris say goodbye and remembers he had what they have, and he wonders if he'll be able to get that back.

"I know that face." Snart says and Peter turns to face him. "The Spider-Man has a broken heart. Wanna talk about it?"

"No, not really." Peter says.

"If we're going into a heist, it's best to go in with a clear head. Especially for a job this big." Snart informs him.

"What do you do when the woman you love is on the opposite side of the war you're fighting?" Peter asks Snart.

"Oy vey, you heroes and your emotions." Snart complains and wishes he did keep it to himself. "Which is more important to you, the side you're on or the woman?"

"Both." Peter admits. "I love her, but I can't join her on the dark side."

"Then that's something you need to decide. Wether you love her enough to save her and pull her to your side, or you're willing to let her choose the dark path, and become someone you'll need to stop and can't love." Snart tells him and Peter decides to think of that information and is ready to head out.

"You ready?" Peter asks him, wanting to forget about his problems for now.

"Whenever you are, partner." Snart says and the two walk off as Peter sets his timer for four hours. "What's that?"

"It's how much time we have left before me and the Flash loose the women we love." Peter explains as they leave and he places his Velocity-Spider helmet on.

-

Snart and Lyla enter ARGUS with Snart in handcuffs and his cold gun.

"Director Michaels. I thought you were en route to San Francisco." One of the guards say.

"We received a unexpected gift from the Flash." Lyla says and he realizes who he is.

"Captain Cold?"

"Always nice to meet a fan." Snart replies.

"Taking him to lockup before I'm en route to San Francisco." Lyla explains.

"Of course, well just need your ID." He tells her.

Lyla gives it and it goes through perfectly.

"And your eye scan?"

Lyla does it and it matches up perfectly.

Peter needs to remember to thank his doppelgänger for this amazing holo-tech he gave him.

"You boys really dot the I's And cross the T's." Snart states to this overprotective security.

"And finally, Director Michaels; Elvis, banana." He says and Peter has no idea what that is.

"It's word association." HR tells them from the comms. "You have to come up with the next correct words in the sequence."

"Peter, you're gonna have to stall." Cisco tells him since they never heard of this.

"Oh, screw it." He says and quickly speeds and knocks him and his partner out before deactivating the hologram and revealing him in the Velocity-Spider.

"Getting rather violent for a peacekeeper in such a young age." Snart comments.

"Yeah, what were you doing at this moment?" Peter asks as Snart was able to get himself out of the handcuffs.

"Magic." Snart answers, jokingly.

"Okay, that was neat." Peter admits.

"Was a neat trick, yourself." Snart comments to his device.

"My doppelgänger from Earth-38 invented it. Uses it to create holograms of him to make himself look like others." Peter explains and hands him the cold gun and they follow Cisco's directions.

They make their way through the facility and come across their most secure criminals.

Lizard

Mysterio

Grodd

Electro

Dr. Octopus

Carnage

Rhino

Kraven the Hunter

Vulture

Scorpion

Juggernaut

Mr. Negative

"Who's Grodd?" Snart asks.

"Telepathic gorilla. Hates me almost as much as dr. Octopus does. This must be where Lyla moved the Sinister Six and other villains after they escaped from Iron Heights once, probably didn't want to take the chance again." Peter guesses as they look and sees the power source and the comms aren't working near the vault. A 10,000 lock that takes three different people with three different passcodes to get in.

It took Snart almost half a minute to get through.

"37 seconds. I must be out of practice." Snart states to Peter.

"ARGUS should ask for their money back." Peter says as they're about to go in but Snart stops him.

"Make the plan, execute the plan." Snart reminds him.

"Expect the plan to go off the rails." Peter adds when his senses do in fact alert him something is here when King Shark slams into the window and they both hide on the side of the doors.

"Throw away the plan. Seen a lot of things, but a half-man, half shark takes the cake." Snart says.

"I can't believe this, ARGUS said they were going to help King Shark, not this." Peter states in anger and confusion.

"King Shark, that's adorable." Snart comments.

Peter thinks for a minute and thinks of something he once saw on tv. "Give me your gun." He asks Snart.

"So you can do what exactly?" Snart asks.

"Most sharks are cold blooded, but King Shark is a warm blooded great white. Meaning that if we freeze the room enough, he should fall asleep and we will be able to go in there and take the device. And with this suit, I should be able to stand the cold but my suit's special features won't work in the environment." Peter tells him the plan.

"I like it." Snart says and passes the gun to Peter who takes a piece of the gun apart and throws it into the room and they watch as it releases a cold atmosphere into the room.

It didn't take long for King Shark to go down and they look at the cold cloud covering the ground.

"By all means, you first, Sixth Sense." Snart tells Peter knowing he prefer the person who can sense the danger to go first.

"I see dead people." Peter whispers as a joke as they enter just for his senses go off as King Shark growls through the ice.

"Reminds me of Jaws. They didn't show the shark because they couldn't afford to make it look good." Snart tells Peter as they head towards the device when King Shark's tail fin sticks out from the ice.

The two stand perfectly still as the fin goes down and he goes unconscious.

"How long do you think that'll keep him occupied?" Snart asks Peter.

"Until the room temperature rises above 58.8 degrees." Peter answers and knows that won't take long with a warm blooded creature in here.

They find the device and it looks like something you'd find in the park of New York but a piece of it slides off as Peter grabs it.

As soon as he removes it, King Shark wakes up and the doors begin to close.

Peter works fast and grabs Snart before webbing the outside of the room and pulls them out when Peter drops the device.

Before it could be crushed, Snart grabs it at the last second as King Shark looses his arm. "Ouch. Been there." He comments on the arm and raises the device to Peter. "Indiana Jones much?" He asks as he hands it back to him.

"This place will be crawling with ARGUS agents in two minutes." Snart warns Peter as they stand and watch King Shark regrow his missing limb.

"Okay, time to get out of here." Peter says when his senses go off yet again and he turns to see Lyla is here with guards raising their guns. "Hey, Lyla." He greets calmly.

-

Lyla brings the two to her office and handcuffs them both, which didn't exactly help against Peter.

"I told you I couldn't give you this." Lyla reminds him.

"You technically said you couldn't give it to Barry. I'm not Barry." Peter replies. "Besides, I'm trying to stop the deaths of hundreds of people and saving the woman I love. I'll die I needed to."

"I heard about what happened with Caitlin, Felicity told me." Lyla tells him and let's out a sign. "I knew even way back when we first met, I saw when you loved someone or even cared for anyone, you risk everything to save them. You're willing to die protecting the world and you don't let your emotions get in the way." She says and Peter sees what she's saying then places the device to Peter's hands, confusing him.

"You're just gonna let me have it?" Peter asks him.

"I can't leave Caitlin a cold, heartless criminal knowing that you were focused on this and not her like I know you want to be. And I know you'd do the same thing for me if it were John's life on the line. Or Oliver's. Or Felicity's. Or just about anyone we've come into contact with." Lyla explains to him. "Now go. And get him back from wherever he came from." She says referring to Snart.

"Took the words right out of my mouth," Snart states as he starts walking off.

"And Peter..." Lyla call's and Peter turns back to her, "nice suit."

"Thanks." Peter replies as he leaves by placing his mask back on and speeds Snart off to Star labs and sends a message to Barry they have it.

-

Barry speeds back to Star labs with the news after dropping Snart off onto the past.

"They have it. Peter is on his way with the device as we speak." Barry tells them.

"Yes, yes!" HR says, happy that they did it.

"Hey, where's Iris?" Barry wonders.

"Oh, she's on Earth-2 Star labs, safely stored away." Cisco assures him when Barry turns around and reveals its Savitar.

"Thanks." Savitar says before speeding off.

-

Miles, Wally, and Harry are ready, waiting to fight the God of Speed when he appears in the middle of the room.

Miles goes charging in and punches his head clean off, but it was able to reassemble and Savitar throws Miles into the wall and breaks Wally's leg and continues to Iris.

Joe and Harry do their best to keep him back when Miles swings in and states webbing every piece of Savitar until he was trapped in a cocoon of webbing.

"Ha!" Miles cheers when his senses warn him of something and they turn to see Savitar abandoned his suit.

"It's really true." Joe says, as he didn't believe at first Savitar was Barry. "Listen to me. You were my son once. Whatever I did to make you feel this way...I'm sorry." He apoligizes.

Miles takes this as an opportunity to sneak up behind Savitar and charges up his venom strike.

"That's not my name." Savitar tells Joe.

"Barry..."

"THaT's NoT My NaME!" Savitar tells him and Miles goes to punch Savitar in the back when Savitar speeds and throws Miles against the wall and starts vibrating his hand into Miles' rib cage. "You think I forgot about you, baby Spider-Man?"

Miles would have made some sort of quip but he was more focused on trying to breath and trying not have this guy crush his ribs.

"Please, stop, Okay!?" Iris begs of him. "I'll go with you, just please, do not kill them." She asks of Savitar.

"I'm not gonna kill them now." Savitar promises while chuckling. "They...need to watch you die first." He says before speeding off, taking his suit and Iris before vanishing.

"Where's Frost when you need her?" Miles wonders even when Harry explained she was still in New York cleaning up the last of one Symbiotes.

Barry speeds in and sees he was too late and Iris is going to die in less than an hour left before she dies.

-

Barry brings Wally and Miles back to their world and their both down for the count as Savitar did a number on the two of them meaning the original heroes are on their own.

"What now?" Joe asks them.

"We go to Infantino Street, we know exactly where Savitar's going to be and when he's going to be there." Barry tells them.

"Is the bazooka ready?" Cisco asks Tracy.

"It should be able to trap Savitar onto the Speedforce." Tracy answers.

"I can't be here to know the plan, and you know where I'll be." Barry says and leaves them to plan.

Cisco and Peter were walking down the halls, all packed and ready to go when Cisco gets a vibe.

He saw Killer Frost in the location where he saw the two of them fighting.

"Cisco, you okay?" Peter asks.

"I saw Killer Frost. I saw this coming. The two of us fighting in the forest." Cisco tells him.

Peter was about to tell Cisco to go to her when what his future self told him comes back to him. He said to choose Caitlin when the time came...this must be that time.

"Go help Barry, I'll go to her." Peter tells him the plan and leaves the base to get back to his suits.

-

Peter sped through Central City until he returned to the Spider Cave and heads to his other suit displays and comes across the one he needs.

The Future Foundation Spider-Man suit.

It was a almost completely white costume with a black spider emblem and two giant yellow eyes for him to see through.

Fox said that it was literally made from a foundation that not yet existed and it had the characteristics that will be able to keep him safe in space like temperature environments. He explains it was created for when he had to fight during the winter which is why it's all white.

Hopefully, it'll be what he needs to fight Caitlin.

-

Infantino Street, Barry speeds in and sees the news reports have mostly been changed.

From Flash stoping Plunder, it was Kid Flash and Spider-Man.

And instead of Killer Frost still at large, it was now Good Samaritan metahuman still unidentified. Referring to the fire that Killer Frost took out.

"Everyone, stay alert." Barry warns them.

Joe has taken HR's place on the rooftop and he's ready.

HR and Tracy were in the van and are hoping the basooka works.

-

In the forest, Peter is all dressed in his suit and is ready to fight Killer Frost and sees she got a head start freezing up everywhere.

"I know you're here, Caitlin!" Peter calls out. "Come out and face me."

"Not exactly who I was looking for." Frost says as Peter sees her step out of the woods.

"I know. That's why I came. You want to kill someone? Live up to your name?" Peter asks of her. "Then let's kill two birds with one stone. I'd die before I let you cross that line." He dares of her.

"Savitar thought this would happen. And said to join him as a god, I have to cure myself of Caitlin by killing the one person she loves more than anything." Frost tells him. "Nice wardrobe change by the way." She comments on the suit.

"You know I'd die for you, Caitlin." Peter reminds her.

"Good. That makes this easier." Frost says as she shoots ice at him and Peter dodges them all and the ones that actually hit him don't penetrate the suit.

"I'm sorry." Peter says as he starts shooting webs and flipping around to dodge her icicles.

-

Barry is waiting for Savitar as he finally shows up with Iris.

"Flash...this is it. Now the moment is upon us." Savitar tells him. "My ascension to become a god."

"Not tonight." Barry promises.

"Show me your the hero." Savitar dares. "Let's see what happens."

"I'm gonna stop you." Barry promises as he speeds off and back with the bazooka and starts shooting at Savitar as he speeds around the place until Barry finally catches him and it becomes like the ending of Ghostbusters when they crossed the streams.

They think they've done it, they won when the bazooka fails and Savitar is free.

"Why didn't it work?" Barry asks as he drops the bazooka.

"I spent an eternity in a trap just like that. You think I didn't know how to prevent it from happening again?" Savitar asks as he holds the philosopher stone. "It's made of calcified Speedforce energy, and you have given it to me."

"No...guys!" Barry calls and they see they can't do anything.

"You stuck me with Speedforce for an eternity of hell. Now, welcome to yours." Savitar says as he holds iris up.

"Don't! Don't do this!" Barry begs of him.

Now, finally I am free of you." Savitar tells him.

"Barry...I love you." Iris tells him.

"No, don't say that. I'm begging you!" Barry says.

"You lose, Barry." Savitar says as he gets ready to kill her by pulling out his blade.

"No!" Barry says as he speeds up to Savitar to stop him.
