King Shark

3 weeks Later

It's been 3 long weeks since Jesse was rescued from Zoom, and Dr. Light paid the price. Naruto had been beside himself with sorrow and anger while he was cradling her body in his arms before Linda arrived with lunch and saw her Earth 2 counterpart laying dead in Naruto's arms

It was a releif to Naruto but it still filled him with grief since Linda of Earth 2 was still dead, and they would bury her on her Earth soon as they dealt with Zoom

Currently Team Flash was watching the survellience footage of Naruto who was currently in the Danger Room, which was glowing red from the gravity machine being dialed up to 150x Earth Gravity

They watched as Naruto panted before suddenly he kicked his right foot up into a backflip, and threw a right, and left punch, followed by a left back kick that he also flipped with and began to flip forward 4 times, before he began to go through his katas (Goku 50x Gravity Training in Namek saga)

"Does he always work out like that?" Jesse asked in awe, as Naruto walked to the gravity machine and dialed it up another 10 notches, before he struggled to walk to the middle of the room and began to do one-handed pushups

"As a speedster, Nathan heals faster and his body grows stronger so he can handle the strain of this. It's been a while since he actually worked out to a degree like this though." Caitlin said

"It's ingenious really. The gravity is slowing him down plus the added weighted clothes he is wearing, and his body weight, when he gets used to the gravity and comes out no one will be able to keep up with him. In speed or strength " Harry said sipping his coffee

"That's good to know.' Diggle said walking into the room with Lyla beside him

"Dig? Lyla? How's little Sara, and Baby John?" Caitlin asked standing up and hugging Lyla

"The twins are fine, and how is little baby Flash?" Lyla asked smiling

"5 months to go, we can't wait." Caitlin smiled rubbing her belly bump

"Hey Dig, Lyla. What're you guys doing here?" Cisco asked walking into the cortex

"We came to give Nate a head's up." Diggle said

"About what?" Caitlin asked

"A meta-human who escaped from A.R.G.U.S. custody, goes by the name King Shark." Lyla said causing the geniuses to blink in surprise

"King Shark? You mean the half-man/half-shark that tried to kill Nate months ago." Cisco said getting nods

"I thought he was dead." Caitlin said

"That's what A.R.G.U.S. wanted you to believe when they snatched him up, but believe me, this half-shark is very much alive, and his biological imperative is telling him to do one thing. That's kill The Flash." Diggle said

"We're gonna need a bigger Flash." Cisco said

Moments Later

Naruto was using a towel to wipe the sweat from his face and upperbody as Lyla and Jesse gazed at him wantonly, "So how do you know about King Shark?" Naruto asked looking at Diggle

"Well, as the new Director of A.R.G.U.S., Lyla's job is to clean up Amanda Waller's messes. King Shark was one of the bigger and weirder ones." Diggle said walking over to stand beside his wife who snapped out of her daze

"Yeah, and it appears under her directives, A.R.G.U.S. had been monitoring meta-human activity for the past two years." Lyla said

"Why?" Caitlin asked

"Well, to see if any of those powers could be exploited." Lyla said

"Weaponized." Wells corrected getting a nod from Lyla

"How do you know that he's coming after me?" Naruto asked taking a shirt off the desk and putting it on

"While in our custody, he kept saying the same thing. "Zoom wants The Flash dead" And although he removed the tracker we had in him, the readings we did receive show he that was headed towards Central City." Lyla explained

"Let him come." Naruto said

"Nate, this thing is a killing machine. We just came here to warn you, man. Let A.R.G.U.S. handle it." Diggle said

"It's alright Dig. Zoom and his Earth-2 henchmen have been coming after me all year, and this is the last one. I'm not gonna just wait for him to attack. I'm going after him first. I owe that to Linda." Naruto said getting nods from his team, "Wells, he's from your Earth. What do you know about him?"

"Real name, Shay Lamden, he was a get this marine biologist before my particle accelerator changed him into King Shark, and Zoom put him under his control. Zoom sent him to this Earth to kill Nathan. I just followed."

"You track Grodd down. Can you find King Shark too?" Naruto asked

"I can try." Harry said getting to work

"Okay, well, all these locations are next to a body of water." Naruto noticed

"There must only be a few hours before he needs to get back into the water to re-oxygenate his blood." Caitlin said

"I can take the waterfront. Can you have your team handle the rest?" Naruto asked Lyla who nodded

"I'll get them on it." Lyla said walking off

"What about Dr. Lamden's doppelganger? Maybe he could help us somehow." Naruto asked Cisco who was on the computer

"Or not. Looks like he died when the particle accelerator exploded." Cisco sighed

"What about next of kin?" Caitlin asked

"He's got a widow, Doctor Tanya Lamden. She's a research scientist at Nautilus Labs, and she studies wait for it sharks." Cisco read

Naruto looked to Caitlin and Cisco, "I need the two of you to go and see if she's discovered anything in her research that could help us."

"Sure." Caitlin smiled

"Great." Naruto said before he saw he had a text from Linda as Diggle, Cisco, Caitlin, and Lyla headed for the exit

"Hey, Digg. How's that helmet treating you?" Cisco asked

"Could use some improvements. I'll get to work on it." Cisco said getting a nod from Diggle

Naruto looked at the picture of King Shark and began to roll his wrist as lightning arched around his body before he looked to his palm and suddenly the sound of energy swirling was heard in the room

Naruto's House

Naruto walked into the house to see Linda sitting on the couch watching TV and with a sigh he walked over and sat beside her, "Hey." he greeted

"You don't have to treat me like glass, you know." Linda said causing Naruto to look at her, "I know what happened with my doppelganger shook you up, hell it shook me up too, but this should just serve as a reminder of what we risk to protect the city that we love."

Naruto nodded, as for the last 3 weeks he had been more careful around Linda

"Im going to be heading up to Alex' place to train. You just make sure you get that son of a bitch." Linda said

"I will." Naruto promised before the two shared a kiss

Nautilus Labs

The two were standing before Tanya who was focusing on her work, "Why? It's been two years since your particle accelerator exploded. Seems a little late to be asking questions about my husband, doesn't it?"

"Your husband passed away from cancer, correct?" Caitlin asked

"I suppose you could say that. It only took three days for every cell in his body to grow uncontrollably. Whatever cancer he had, it turned him into something not human." Tanya frowned

"Well, that's why we're here, actually. There's a meta-human in Central City whose body has mutated the same way as your late husband, but he lived and is using his mutation to hurt innocent people." Caitlin said

"What does this have to do with me?" Tanya asked with a frown

"We've read about the research you're doing here on sharks." Cisco said

"Mm-hmm, yeah, I've had some encouraging results, although still preliminary."

"Would you allow us to take a look at your findings, it could help us stop this meta-human from hurting anyone else." Caitlin requested

"You're with Uzumaki Labs. I'm just supposed to trust you?"

"Please, Mrs. Lamden. This could help save lives." Cisco said

"I'll email you what I have." Tanya said walking off as the two sighed

"Thank you." they said

Joe's House

Naruto was sitting on the couch working on a power suppressing bracelet, it was designed to completely suppress dark matter in the bodies of meta humans everywhere, he was working on it for a new friend he had met on his jog

Flashback

Naruto was running through Keystone when he saw a familiar man up ahead on the sidewalk pause in his jog and look into a alley before he electricity from his palms and arrived to see the man take out a man with a gun held to another man

"Jefferson?" Naruto asked causing Jefferson Jackson to look at him

Jefferson Jackson step brother of Joe West turned to see The Flash watching him, "You?"

Jefferson watched as The Flash lifted his mask a bit so that he could see his face, and widen his eyes as he was looking at the boy his estranged brother had taken in

"Naruto."

Later

Naruto was standing in the kitchen looking at pictures of a young him, Iris and two other girls, back before Joe and Jefferson had their big argument

Jefferson walked up with a mug of coffee, "No thanks, Coffee makes me twitchy." Naruto said

"Suit yourself.' Jefferson shrugged sipping the coffee

"So your a metahuman?' Naruto asked getting a nod from Jefferson, "Does Joe know?"

"Yeah." Jefferson nodded

"What happened between you two? I mean when I was a kid you both were so close. And now 9 years later, neither of you have made any inroads to getting back to a good place." Naruto wondered

"You know how Joe is. He's my overprotective big brother, when he found out I was going out at night and cleaning up the streets, he freaked."

"You were a vigilan- oh my god you're Black Lightning." Naruto said with wide eyes

"I was Black Lightning. That isn't me anymore. Black Lightning took my wife and my brother from me."

"Joe is over that trust me. It took a while for him to be okay with me being the Flash." Naruto said

"He knows?' Jefferson asked with a raised eyebrow

"Yeah, but I have to ask, how?" Naruto asked

"I don't know. I just always had my powers, my dad said my mom while she was pregnant with me had some kind of accident, he never went into detail before he died so I think it had something to do with that accident." Jefferson said standing up and walking over to Naruto, "Black Lightning is gone, and he's going to stay gone. It was nice seeing you Nate, I'm also really sorry about Henry."

Naruto nodded before the sound of two footsteps could be heard, "Hey dad what's for bre..." two girls appeared in the doorway and paused when they saw Naruto who smiled

"Hey Nissa, Jen." Naruto greeted as Anissa and Jennifer looked at him in shock before with excited squeals they rushed him

End Flashback

Whatever accident Jefferson's, and Joe's mother had while she was pregnant with Jefferson somehow have her son the ability to control electricity unfortunately he didn't want his powers so Naruto was making this bracelet to help him suppress his powers

Earlier today he and A.R.G.U.S had searched the waterfront only for King Shark to kill a man and get away, and tonight was family game night

Looking up as Joe walked in followed by the girls Naruto put up the bracelet

"Perfect he's already here," Joe said to Whitney causing Naruto to raise an eyebrow

"Um so Nate I'm working on my engineering project and I was wondering if you would lend me some help?" Whitney asked

"Sure." Naruto smiled causing Whitney to grin

"I'll go get my bag." Whitney said before she ran off

Naruto looked to Joe and said, "While she's gone it'll give me time to tell you that you should reach out to Jefferson."

Immediately Joe frowned as his back straightened, "

"I ran into him earlier while I was jogging, It's been 9 years since you and your brother has had a real conversation Joe."

"Its complicated Nate."

"Are lives are complicated, family relationships doesn't have to be." Naruto said as Joe sighed, "You didn't agree with him being Black Lightning, and now you're an important member of Team Flash."

Joe looked down before he blinked in surprise and looked at Naruto, "You know?"

"Yeah, why wouldn't you tell me your brother had powers?" Naruto asked

"To be fair it wasn't my secret to tell, and I told him I would tell no one, secondly I always thought his powers came from the suit he wears." Joe said getting a nod from Naruto, "Ill give him a call in the morning."

Iris and Whitney walked in at that moment, "Give who a call?" Iris asked

"Your uncle." Joe said

Whitney blinked, "We have an uncle?'

"Dad has a half-brother. They had a big argument 9 years ago." Iris said causing Whitney to look at Joe who sighed

"It shouldn't have taken this long." Joe said

"So what exactly did you need help with Whitney?" Naruto asked who handed him her tablet

"So, this is what I got so far for my project essay to get into CCU's engineering program." Whitney said as Naruto looked over what Whitney was working on

"Turbine supercars? Like jet engines?" Naruto asked looking up at her

"Yeah, yeah, it'd use an engine like the ones they have in some helicopters, only it'd run on bio-diesel." Whitney nodded

"Awesome, but remember you are going to need to make it environmental friendly how it'll affect everyday life, and cheaper ways people can afford to refuel it." Naruto said

"That's where you come in." Whitney said sitting beside Naruto "You have any ideas?"

"I might." Naruto smirked before the family jumped when they flinched as the roof was suddenly destroyed and they looked up to see King Shark looking at them

"Where's The Flash? I know The Flash is here. I can smell him." King Shark said sniffing around and secretly Naruto out the power-suppressing bracelet on his wrist and immediately felt his perception and the way his body felt change, and a feeling he's missed come rushing back

Whitney gasp, "Nate?' She asked causing Joe, and Iris to look over and gasp as well, seeing Naruto's spikey sun kissed blond hair had turned completely white, he also had two horns sprouted from his forehead and six magatama markings appeared across his chest, while his eyes were red with slot pupils

"What?' Naruto asked keeping an eye on King Shark before he saw Joe motion over to a mirror and he looked over before his eyes widened seeing his appearance, the closest thing he could call it was when Obito had became the Jinchurriki for the Juubi

"Later, get out of here." Naruto said to Iris, and Whitney before Iris lead Whitney upstairs while Joe opened fire on King Shark but the bullets had no effect, when in a flash of light Naruto was before King Shark and punched him in the chin, causing the half shark half man-monster to stumble back into the street

Naruto smiled as he landed on the street, as he could now feel a huge abundance of chakra flowing through his body, now that the dark matter was completely suppressed

"Ive missed this feeling." Naruto said watching as King Shark got up and quickly Naruto sped in and a Giant Rasengan was in his hand but when King Shark swiped an arm to knock Naruto away, the now white-haired hero appeared above Kong Shark and slammed the Rasengan into his back causing King Shark to yell in pain as he was drivin into the street

Naruto let the Rasengan disperse, and flipped back watching as King Shark struggled up to his feet, "I'll remember this." King Shark said before he left as quickly as his injured body allowed him to, and quickly Naruto ran to the house to see if everyone was okay while A.R.G.U.S. SUV's speed around the corner after the Shark meta

Joe, Iris, and Whitney watched as Naruto took off his bracelet and immediately his body vibrated and lightning surrounded his body causing Whitney's eyes to widen as Naruto's body returned to normal

"Y-your the Flash?" Whitney asked

"Yeah." Naruto nodded

"What was that?" Iris asked

"You remember how I told you how I had 9 chakra entities in my body when I was reborn here?" Naruto asked getting nods from Joe, and Iris while Whitney looked confused, "The side effect it had on my body would've been that had I not got hit with the bolt of lightning that turned me into the Flash."

"So basically, even if Zoom took your speed you would not be helpless?" Joe asked

"I'd say I'd be even more of a threat. " Naruto smirked clenching and unclenching his fist

"Would you three please tell me what the hell is going on?" Whitney called

"Sure, just let me fox the roof." Naruto said before he raced off in a streak of purple lightning and a minute the roof was fixed as Naruto walked in with a paper towel after he washed his hands, "Now it's a long story, I guess I should start with...before I was Nathan Allen, I was Naruto Uzumaki."

Morning, Uzumaki Industries

Naruto was in the cortex with Cisco, Jesse, Caitlin, Harry, John and Lyla, "Just when you thought it was safe to go back in the suburbs, King Shark shows up at Joe's house."

"Yeah, I think we underestimated just how of a shark he was." Naruto said

"How do you mean?" John asked

"Sharks are predators. In order to track their prey, they use what's known as passive electrolocation." Caitlin said as she brought up a hologram of a shark, "

"Passive electrolocation?" Diggle asked

"Yes, it's how they sense the bioelectric potential around a fish's body." Naruto said

"King Shark sensed electricity in your system." Harry said

"Okay, that explains how King Shark can track Nate, but how is that going to help us track him?" Lyla asked

"We flip it. Instead of King Shark being the predator, we make him the prey, and track him using active electrolocation."

"We reprogram our satellite to generate a specific electric field and then measure any electrical distortions that correlate with a 1-ton walking shark." Cisco said

"That'll help us get him. You help me out?" Harry asked Jesse who smiled

"Sure." Jesse said following after her dad

"Great. Let us know when you locate him and we'll provide backup." Lyla said getting a nod before she looked to John "Let's get the team ready."

As everyone began to get to work, Naruto began to work on his own little project: A dark matter suppressor designed so that he could cut out his speedster abilities at will in the situation they got him into situations he couldn't get out of, and give him back his chakra till he could find a way to use both at the same time

Later, Waterfront

Naruto, Caitlin, John, Lyla and a few A.R.G.U.S personnel walked along the waterfront, "What exactly is that?" Diggle asked looking at the mannequin of the Flash out on the buoy

"That, my friend, is bait." Naruto said cracking his knuckles today he was going to see what getting used to 150x Earth gravity did for a speedster

"You made a Flash lure?" Lyla asked

"It's the best I could come up with given the time frame. It's rigged to mimic and enhance the electric field Nate's body generates. King Shark takes one whiff of that, cue the "Jaws" soundtrack. Also stuffed it with enough tranqs to knock him out for a month." Cisco said from the cortex

"Should make him a lot easier to reel in. And that container is strong enough to hold him once he's sedated?" Diggle asked

"It's made of promethium metal. It's impenetrable." Harry said in the cortex with Cisco and Jesse

"Meanwhile, we'll be able to keep track of King Shark with this, and the cameras that are on the lure. Whatever he does, we'll have eyes on him." Caitlin said

"All right, then. Let's go fishing." Lyla said with her binoculars

"Caitlin, I don't understand why I can't be the one playing Quint in this scenario. I should be the one out there, not you." Cisco said

"It is my plan Cisco." Caitlin said

Naruto was standing with Diggle waiting on King Shark, "Water is this monster's natural habitat. He's gonna be a lot stronger here. You sure about this?"

"Have some faith Dig. Water may be this thing natural habitat, but I'm still stronger than him." Naruto said

Hours went by and King Shark had yet to show, but the rain did unfortunately "Maybe he's not gonna fall for this." Diggle said with a flashlight

"He's a shark. He'll come." Naruto said before he got on the comlink "Anything, Cisco?"

"Uh, nope, nothing that looks like it could be him." Cisco said with a small yawn

"You programmed the satellite though, right?" Harry asked

"Yes, Harry." Cisco said

"I mean, you punched in the correct parameters?" Harry asked

"You're insulting my intelligence." Cisco argued

"But they've been waiting for hours. Did you punch in the correct parameters?" Harry asked

"I know they've been out there for hours, but you're insulting my intelligence with this, okay? I know. Okay." Cisco said as Naruto sighed

"Hey, you set the right distortion scope, right?" Jesse asked causing Naruto to snicker

"Oh, for real?" Cisco asked offended, "Okay. You know what, we're gonna play a game here. It's called, if you're from Earth-2, you're gonna be quiet, okay?"

"Yeah." Jesse said

Naruto turned in Caitlin, and asked "You sure you don't want to go inside instead of standing under this umbrella?" he asked

"I'm fine. This is the first step to your rematch against Zoom. I cared about Light just like you and Linda. We'll get you back there and he will pay for all he lives he has ruined." Caitlin said getting a nod from Naruto

"Guys, incoming. He's headed for the bait!" Cisco yelled over the coms, causing Caitlin go look at the device in her hands to see a heat signature headed for the bait, immediate everyone looked to the buoy just in time to see King Shark jump from the water and eat the mannequin

"He ate the lure!" Caitlin said

"Dig reel him in." Naruto said and immediately John got to work

"Come on." Diggle said looking up as he held the button to reel the cable in only for them to discover the destroyed mannequin "Where'd he go?"

"He's headed for the docks." Cisco screamed over the come

"Go." Naruto said to Caitlin and with a nod Caitlin ran back

"Get ready to fire!" Lyla ordered as King Shark jumped out of the ocean and landed on the docks as the A.R.G.U.S. soldiers shot at him but the bullets proved no affect causing John to raise a hand and the soldiers stopped firing and they backed up

"Those guns won't stop me, Flash. First I'll kill y-ush!"

Naruto punched King Shark in the gut causing a shockwave so powerfull that it split the lake, as King Shark flew back over the water, before Naruto sped forward and gave an uppercut that sent King Shark into the air with Naruto still in pursuit

Team Flash and A.R.G.U.S watched as King Shark was attacked from multiple directions by a streak of purple lightning before they saw Naruro appear and kicked King Shark to the lake, causing a large splash, before Naruto landed on the lake and immediately ran in a circle

"What the.." Cisco said

"What?" Jesse asked

"Nathan's lightning its turning white." Harry said

Naruto's purple lightning changed to a white with a hint of gold color, as the water picked up behind him before a large tornado of water electrified by Naruto's lightning was raging causing everyone to look on in shock, before in a flash of lightning Naruto was now on the docks not the least bit exhausted

The tornado began to subside and when it did, King Shark was seen unconscious with lightning arching off his body as he fell into the lake

"Now we can reel him in." Naruto said causing Diggle to smile and slap Naruto's shoulder.

AN: Anyway so I made Jefferson Pierce aka Black Lighthing the half brother of Joe West. He may not be in the Arrowverse but then again this story doesn't take place in the Arrowverse now does it.
