A/N: Meant to shout out my friend's Youtube Channel: WolfxVoidx. She only has a couple of videos but they're great, check her out whenever you get a chance if you like multifandom type videos. For those who only watch Arrow or Originals respectively, I'm going to try to explain everything out for you guys so everyone can understand the story of both shows and who characters are. But here's Chapter 1, hope you enjoy.

Chapter 1

Arrowcave

Felicity Smoak spent most of her free time in the bunker. After the death her boyfriend, Billy Malone, at the hands of Prometheus, she needed a way to take her mind off of things. What better way to do that than being Overwatch.

Oliver walks with great pace towards Felicity, as he always does, "What do we have on our potential serial killer?"

"Besides their obvious love of making a mess? No. Are you sure we're dealing with a serial killer and not a serial mountain lion? All of these victims were either decapitated or ripped apart. I think I saw a heart somewhere in here too." Felicity answered.

"Mayor Landrich did say this person was dangerous." Oliver told Felicity.

"Well with John and the team working on an ARGUS mission and Curtis on leave to deal with Paul, we're the only ones here to handle this." Felicity pointed out.

Oliver let's out a sigh as she is right as his phone rings, he looks to see that it was District Attorney Adrian Chase.

"Adrian?" Oliver answers.

"Oliver, you have to see this. Turn on the news." .

Oliver changes the monitor to the news channel,

"...a limousine was found last night, five people were found dead at the of the victims was identified as New Orleans mayor, Mitch Landrich." Oliver and Felicity watched on shocked at this discovery, "Landrich was found crushed under the limosuine that flipped over on top of him. Sources are saying that he was seen last night before the incident coming out of City Hall after a meeting with Star City mayor, Oliver Queen. Could this be the works of the Throwing Star Killer-"

"I have to go." Oliver interrupts as he rushes out the bunker.

"I'll check the street cameras to see if they captured anything." Felicity told Oliver as he left.

City Hall

"Star City is shaken at the death of Mayor Mitch Landrich," Oliver announces as he stands in front of paparazzi at City Hall, "My condolences go out to his family back in New Orleans, I have already made sure that they are taken cared of."

Oliver pauses for a moment before continuing his speech, "Mitch came to warn me. He came to me about a potential threat, looming in our city. I just wish I could've acted on it sooner… Deputy Mayor Lance and I are working alongside SCPD and the Anti-Crime Unit to ensure that whoever did this is brought to justice. If you see anything out of the ordinary, please contact SCPD. Any questions?"

"Could this new threat be working with the Throwing Star Killer?" A female news reporter asks.

"We are unsure on who the culprit could be, but we are not ruling out the idea." Oliver answers.

"In the report, it says that the limo was forcefully flipped over and that the doors were pried off the vehicle, is there a possibility that we are dealing with one of those metahumans from Central City?" Another female reporter asks.

"As of right now, there is not enough evidence to conclude that question."

Oliver's phone vibrates, he checks it to that it was a text from Felicity reading 'I found something on footage'. Oliver turns back to the crowd, "That is all, thank you for your time."

Oliver leaves the stand with Thea, Lance, Adrian, and a couple of security guards back into City Hall.

"That was short and sweet." Lance told Oliver.

"It was all I can come up with, I have something on the culprit. I'm going to leave City Hall to you and Thea, if anything comes up let me know."

Lance nods in agreement as Oliver heads out of the building.

Arrowcave

"I got here as fast as I could." Oliver says as he marches in.

"Take a look at this," Felicity tells Oliver.

Oliver and Felicity looks at the monitor, they see a limousine driving down the street when all of a sudden a black blur charges at the vehicle, causing it to crash into a nearby telephone poll.

The footage shows a hooded figure staring at the vehicle. Three security guards exit the vehicle and start firing at the woman, the bullets look like they had no effect on her.

The figure suddenly blurs away again toward a security guard and snaps his neck before turning and ripping a nearby guard's heart out.

The last remaining guard starts to cower. He turns to run and as he did, the figure was already there, the figure leaps onto him and from what it looks like, bites his neck.

Felicity fast forwards the footage and sees that Mayor Landrich did manage to crawl out of the limo, but he was met by this murderous figure.

The figure grabs him by the throat and throws him into the vehicle. The figure pauses for a moment, it looks like they had a brief conversation. The figure then moves Mayor Landrich's head to the side and bites him, blood squirts from the artery in his neck.

As he slumps to the ground, the figure goes behind the limo and flips it on top of the mayor. The footage ends with her blurring off again.

"So it looks like we can put a check mark beside metahuman. Think this could be our girl?" Felicity says as she turns to Oliver.

"Possibly. Can you play the audio from the footage? It looked like they were talking about something." Oliver asked.

"The cameras on these streets are old, but I may be able to amp the quality if it's not too gargled up. I'll also call Star Labs and see if they're missing any Metas." Felicity reassures.

"Let me know if you find anything." Oliver says.

"Where are you going?" Felicity asks.

"I'm suiting up. Whoever did this is still out there. If this is the woman Landrich was telling me about, then I need to get her off my streets NOW before she kills anyone else." Oliver says, walking toward his suit.

"I get that Oliver, but don't you think we should call back up? You saw what she did out there." Felicity said worryingly.

"If it get's out of hand, we'll call in back up." Oliver tells her.

"I don't know why I even try sometimes." Felicity says rolling her eyes.

Oliver gives her a smirk. Time passes and Oliver dons his green hood. Oliver, now suited up as the Green Arrow, grabs his bow and walks toward the exit.
