I have been planning this for some time. "Arrow V Flash" is not just a one-shot or two-part story. It's a multi-chapter storyline. By the way, this takes place on Christmas, so, obviously, the characters are on Christmas vacation.

NOTE: This story is based on Batman V Superman: Dawn of Justice.

Leave a review after reading, please. (Anything but "please update" or anything sounding similar because it feels pushy)

Thanks to Clash of the Legends, tiny tim, and funnydude for the recent reviews.

December 21 (4 days before Christmas)

It was a noisy, crime-ridden evening in Silverstone City. Fortunately, the Flash and Supergirl are out there to keep everyone safe. The Arrow, meanwhile, was chasing another corrupt one-percenter. Ever since the three costumed vigilantes have appeared on the scene, the public has been going crazy. Nearly every single person in the city is grateful for their dedication to protect them. As for The Arrow, opinions are divided. Half the city thinks he's a killer, while the other half thinks he's a hero, given the fact that the people he kills/put away are corrupt and poison the city.

SCPD Detectives Joe West and Quentin Lance are asked to attend a meeting with Mayor Altman, along with District Attorney Cecile Horton.

"So, what is this meeting about, Mr. Mayor?" asked Joe.

"I want to discuss about The Arrow," said Altman.

"Look, the department is doing their best, but this guy, he's both skilled and intuitive," said Quentin.

"I'm not talking about incarcerating him," said Altman. "I want to talk about recruiting him."

"What?" asked everyone on the table, surprised.

"Adam Hunt. Martin Somers. Leo Muller. Justin Claybourne. Anthony Venza," enumerated Altman. "He's killed or put away some of the worst of this city and public approval has been rising each day. I may not appreciate his methods, but the results are hard to argue with."

"I'm not sure the vigilante would be interested in working for the law," said Cecile.

"I know that, but I have a proposal for him," said Altman. "I just need you to..."

Unexpectedly, an arrow smashes through the window and hits Altman in the chest, shocking Joe, Quentin, and Cecile.

"We need a medic!" shouted Cecile.

While Joe leaves to find help, Quentin looks outside the window and saw who shot the mayor. It appears to be The Arrow.

"Son of a bitch," cursed Quentin.

The Arrow leaves the rooftop and disappears into the night. Quentin turns around and saw Cecile putting her fingers on the mayor's neck. The look on her face tells him the worst has happened.

"He's gone," said Cecile.

Meanwhile, near the edge of Silverstone City, Flash arrives at an abandoned warehouse. He barges in, but the place seemed empty.

"Guys, there's no one here," said Flash through his comm-link.

"But that's where we tracked the cellphone signal," said Cisco.

"Read any heat signatures?" asked Flash.

"That's strange. The only heat signature I can pick up is you," said Cisco. "Maybe our friends have some technology that blocks their heat signatures."

"Not possible. Such technology is decades ahead of our time," said Wells.

The Flash runs around the warehouse until he found something on a work table. It was a Christmas gift box. He opens it and finds a phone. He turns it on and sees messages sent/received by the phone's owner to/from a name that is familiar to everyone in the city.

"Don't you know it's impolite to look at other people's phones."

Flash turns around and saw a familiar face. It was the ice-powered metahuman who kidnapped Jesse Wells. This time, she was wearing something different. She was wearing a long dark blue coat, a corset-like top with a spiked snowflake symbol, a short blue skirt, and thigh-high boots.

"Mistress Freeze," greeted Flash. "Like the new outfit."

"For the record, the name is Killer Frost," said the meta.

"O... kay. I supposed that sounds scarier and cooler, no pun intended," said Cisco.

Flash says, "You killed an innocent girl's mother a few weeks ago."

"That wasn't my intention," said Killer Frost. "I wanted to kill Caitlin Snow, but her mother got in the way."

"Why do you want to kill Caitlin Snow?" asked Flash.

"Just wanted to send Harrison Wells a message," said Killer Frost. "Jesse isn't the only person Wells cares about. Maybe I'll go after Cisco Ramon next."

"Gulp," said Cisco in a high-pitched voice, feeling scared just listening.

"I let you go last time, but it won't happen again," said Flash.

"Well, Come at me," dared Killer Frost.

Flash started running towards Killer Frost. By the time he reached her, Killer Frost takes her hand out from behind her back. The Flash stopped inches from Killer Frost. He looks down and saw her piercing him in the abdomen with an icicle.

"Barry, what's going on? Your vitals are dropping," said Cisco.

Killer Frost removes the icicle from the Flash and then stabs him in the back of his right knee, causing him to shout in pain and collapse.

"Always running towards danger without thinking first. And they call you a 'hero'," mocked Killer Frost.

"Well, what are you waiting for? You call yourself a killer, don't you?" asked Flash, grunting because of the pain.

"As fun as that would be, you're not ready to die yet," said Killer Frost. "I hope you like my gift."

Killer Frost walks away and leaves the Flash lying on the ground in pain.

"Barry, what's happening?" asked Wells.

"I need a minute," said Flash, still grunting and whining in pain.

December 22 (3 days before Christmas)

Laurel arrives at Queen Consolidated's old factory. She enters Oliver's secret bunker and found him exercising on the salmon ladder. It really impressed her how strong and athletic he's become after just one year on an island. Her amazement changed into shock when she saw the scars and burns on his back.

Oliver descends from the ladder and saw Laurel. He quickly grabs his shirt and puts it on before she could see any more of his scars.

"Oliver, I..." Laurel paused, not knowing what to say, still shocked and horrified.

"Not today, Laurel," said Oliver.

While Oliver checks on the names in his father's notebook, Laurel heads to the computer and turns on the news channel. They were reporting about The Arrow murdering the mayor. Laurel crosses her arms and looks at Oliver, giving him the look a parent gives to a child who did something bad.

"I know what you're thinking," said Oliver. "I didn't do it."

"My dad said that the archer stationed across City Hall was wearing a green hood," said Laurel.

"Laurel, after everything's that happened, do you honestly think I would kill the leader of this city?" asked Oliver.

"If his name is on your list," shot Laurel.

"Mayor Altman was one of the few good people in this city," said Oliver.

"So, if it wasn't you, then there's only one other person," said Laurel. "The copycat archer."

"Make sense," replied Oliver. "But why would he pose as me? To frame me? If so, for what purpose?"

"Well, it's hard to do your job if there's a 24/7 manhunt for The Arrow," said Laurel.

"As far as we know, the copycat works for the man who compiled The List, and we just learned that it's not my father," said Oliver.

"He wants you out of the way," concluded Laurel.

"If he thinks that I'm just gonna sit by and let the people on The List continue to poison this city, he's wrong," said Oliver.

"I know you're not one for taking orders, but you may want to lay low for the meantime," suggested Laurel.

"I can't do that," said Oliver.

"Silverstone City has the Flash and Supergirl," reminded Laurel. "They can take care of this city."

"They only go after criminals and metahumans, but that's not gonna save this city," said Oliver. "The people on The List, they're the real problem."

"Speaking of problems, is Thea still rejecting the idea of the Queen Mansion's first Christmas party in five years?" asked Laurel.

"She's stubborn and angry, but I can't blame her." said Oliver. "The party goes on, whether she likes it or not. I'm doing this for my family, not for me. Just because I spend my nights trying to save this city, doesn't mean I don't make room for family."

"You've really changed," said Laurel with a smile.

"I thought I already made that clear," said Oliver.

"Yeah, but you're a completely different person," said Laurel. "The drinking. The girls. The partying. All gone."

"Not everything," said Oliver. "For years, I took you and my family for granted. But deep down, I do care. I was just too much of a party boy to see that. If the island did me any favors, it helped me see the person underneath the playboy persona."

Laurel smiled again. After she learned who Oliver really was, she thought that the person she dated was gone, but she was wrong. There was still traces of the Oliver she knew and loved. He may not show it all the time, but she always sees it.

"What?" asked Oliver.

Laurel catches herself staring. "Oh, um... should we continue my training?"

"Sure," said Oliver.

He picks up an escrima stick and throws it at Laurel. She catches it before it hit her face.

"Nice reaction time," said Oliver.

At S.T.A.R. Labs, Barry was testing his leg on Cisco's treadmill. Cisco and Harrison Wells watched. It wasn't long until Caitlin arrived.

"Hey," greeted Caitlin. "How is he?"

"He's getting better," answered Cisco. "Where were you last night? He needed a doctor?"

"Tannhauser Industries," answered Caitlin.

"Oh, sorry," said Cisco sympathetically.

Barry leaves the treadmill and approaches his teammates.

"So, how're you feeling?" asked Caitlin.

"Well, thanks to my super healing, I think I'm 100%," said Barry.

"I'm sorry I wasn't there last night," apologized Caitlin.

"You were in pain. I can understand that," said Barry.

"So, Cisco told me that the meta calls herself Killer Frost. Sounds better than Mistress Freeze," said Caitlin.

"I promise you. I will stop her and get justice for your mother," said Barry.

"You'd do that for me?" asked Caitlin.

"You're my friend, Caitlin. Of course, I'll do it for you," said Barry.

Caitlin smiles at Barry.

"Man, it's like the only person who can make you smile is Barry," said Cisco.

Barry and Caitlin glare at Cisco. The latter raises his hands and turns away.

"So, did you guys analyze the phone?" asked Barry.

"We did," said Wells. "We analyzed the prints and we got a match. Leonard Snart."

Barry's eyes widened in shock. "Leonard Snart? How?"

"The only logical explanation is... he's Captain Cold," said Wells.

Barry realizes something else. "Which means Heat Wave and Golden Glider are...?"

"Mick Rory and Lisa Snart," said Cisco. "Man, first Barry Allen becomes a superhero, and now the guys who bully him every day become criminals with fancy guns."

"We gotta tell the police," said Barry.

"But we have no proof," said Wells. "The best way we can put them behind bars is capturing them and unmasking them."

"So, why was Snart talking to Maxwell Lord?" asked Barry.

"The phone's number is blocked, so Mr. Lord doesn't know who he's talking to," said Wells. "We read the messages. All we know is that Snart is threatening Lord to hand over Project Kr."

"What's Project Kr?" asked Barry.

"Kr is the atomic symbol for Krypton," said Wells. "Best guess is that it involves Kryptonians."

"Something doesn't add up," said Caitlin. "Why would Killer Frost leave the phone on? It's like she wants you to know about this."

"Well, we need to find out how Maxwell Lord is connected to Snart and Killer Frost," said Barry.

"What are you suggesting, Mr. Allen?" asked Wells.

"Maxwell Lord is having a Christmas charity party tomorrow," said Barry.

"And how are you gonna get an invitation for a party like that? You're not an upstanding businessman or a counselor. You're just a teenager," said Cisco.

"I have an invitation," said Wells. He looks at Barry and says, "You want to infiltrate his party and gather intel."

"Yes, I do," said Barry.

"Okay, but again, you're just a teenager," reminded Cisco.

"No one knows who Barry Allen is. That gives me an advantage," said Barry. "Maybe it's time I become someone else."

Barry receives a message on his phone. It was from Iris.

"Oh, man. I forgot," said Barry, scolding himself. "I was supposed to meet Iris for her interview."

"Then go," said Cisco.

Meanwhile, somewhere in Silverstone City, Iris West was sitting around while talking to someone on her phone.

"Don't worry, dad, it'll be okay," she said to her father on the phone. "Okay, love you, too. Bye."

After the phone call, Iris sees a pickup truck heading her way. Coming out of the truck is a non-Caucasian teenage boy with a camera around his neck.

"Hi," he greeted. "Jimmy Olsen."

"Iris West," said Iris, introducing herself as she shaked hands with James.

"So, you're the SCPN intern I've been partnered with?" asked James.

"And you must be the CatCo photographer I've been paired with," replied Iris.

"So, uh, what do you think of the assignment?" asked James.

"Pretty big for a couple of teenage interns," said Iris. "But Mason Bridge thinks this experience will really help me. You?"

"When you're the first photographer to take a picture of Superman, you can get pretty much get the biggest assignment on Earth," said James.

Iris and James approached a woman who was on the phone. She was a young woman with long, raven black hair.

"Excuse me? Ms. Luthor?" called Iris.

The woman turns her head and saw Iris and James. She tells the one she's calling on the phone, "I have to talk to you later. I have an interview to get to."

Lena hangs up and looks at the two teenagers.

"You're Lena Luthor, right?" asked Iris.

"Indeed, I am," said Lena.

"Fresh out of senior year and already going into the big business," commented James.

"Speak for yourself. You're working in CatCo," replied Lena. "It's gotta feel like an honor."

"Oh, it is," said James.

Lena walks inside her business building, called L-Corp. Iris and James followed. James started taking pictures while Iris turns on her recorder and started interviewing Lena.

"So, Ms. Luthor, what is the goal of your company?" asked Iris.

"To usher in a new era of technological advancement," answered Lena.

"So, you're basically doing the same thing as your older brother, Lex Luthor?" asked Iris.

"While LexCorp and L-Corp do engage in the same field, Lex is more of producing killing machines for the military," said Lena. "My company strictly focuses on making technology to change the future."

Before the interview can go on, screaming can be heard upstairs. A man on fire falls down the stairs, surprising the three teenagers.

"What is happening?" asked James.

Three armed individuals came down the stairs. They were Captain Cold, Heat Wave, and Golden Glider. They fired left and right, trying to make sure everyone was out of their way on their way out. Heat Wave was carrying a small metal crate on one arm and his Heat Gun in the other.

"Well, lookie what we have here. It's the boss-lady," said Heat Wave, aiming his Heat Gun at Lena.

"Hostages could help make our escape easier," said Golden Glider.

"Very well," agreed Captain Cold.

Golden Glider grabs Lena and heads for the exit.

"Hey, let her go!" yelled Iris.

Captain Cold aims his gun at Iris and fires. Before the cold beam could freeze Iris, a yellow streak came out of nowhere and saves her. It was the Flash.

"You have to knack for getting into trouble," said Flash, smiling.

"You have a knack for saving my life," smiled Iris.

"Nice to see you again, Flash," greeted Captain Cold.

"Let Lena Luthor go," demanded Flash.

"Then come over here and take her," dared Golden Glider, pointing her gun at Lena.

Flash zooms over, knocks down Golden Glider, and frees Lena Luthor from her grasp. Captain Cold and Heat Wave fired their guns. The Flash runs around to avoid getting hit. Captain Cold decided to change tactics and targets an employee. He fires his gun. The Flash runs towards the employee and pushes him out of the way of the cold beam, taking the hit. His suit is frozen partly as he lies on the ground.

"You may want to reconsider, Flash," said Captain Cold. "There's a leak upstairs and if that leak isn't taken care of in thirty seconds, this place goes boom."

Captain Cold, Heat Wave, and Golden Glider leave with the piece of tech they stole, while the Flash heads upstairs to repair the leak.

Lena gives the guards an order. "Stop them!" She looks at Iris and says, "I don't want this going on record."

"No problem," promised Iris.

"What exactly was in that crate?" asked James.

"I'm afraid that's classified," said Lena. "You need to leave. We'll continue this interview another time."

Iris and James leave L-Corp.

"Place isn't open for business yet and already, they've been robbed," commented Iris.

"That's Silverstone City for you," said James.

"Hopefully, the Flash can stop those rogues," said Iris.

"That may be difficult. They're long gone," said James, checking the area. There was no sign of the three criminals.

"Where is Barry, by the way?" Iris wondered, looking for him. "Typical. Late as always."

After locking up the latest escaped prisoner of Fort Rozz, Supergirl meets up with Hank and Alex in the main room. They appeared stressed and the other agents were working faster than usual.

"What's going on?" asked Supergirl.

"We've been hacked," said Alex.

"Can't you trace the hack back to its source?" asked Supergirl.

"We're trying, but this proving to be difficult," said Hank.

Supergirl turns her head and found a familiar face.

"Winn?"

Winn turns around and saw Supergirl.

"Hey, Kara," greeted Winn.

Supergirl looks at Hank.

"You think I wouldn't know about him hacking into our system?" said Hank. "Don't worry. I'm not locking him up for that. The fact that he could hack into our system meant he could be useful."

"For the record, I only did part of it. I asked... someone else... to hack in," said Winn.

"But you learned how she did it, therefore, you can hack as well as she can," said Alex.

After a few more minutes, Winn managed to trace the source of the hack. What he found appeared on the screen of every monitor.

"Lord Technologies?" Supergirl was confused.

"How could Maxwell Lord know about us?" asked Hank.

"Son of a bitch," cursed Alex. "We're gonna pay him a visit."

Alex was about to walk away and gear up, until Hank grabbed her arm.

"Maxwell Lord is too big, Alex. We attack him, he reveals us," said Hank. "It could be the end of our operations."

"So, what are we gonna do now?" asked Alex.

"I have an idea," said Supergirl. "It's a terrible idea, but it's the best one I have."

I'm stopping here for now. I hope this was a good start. Remember, "Arrow V Flash" is a multi-chapter story. Be patient for the next chapter.
