Before we start, I just wanted to mention that I will be adding aspects from a previous Avengers/Torchwood crossover in this story. It's not completely necessary to read that story, but if you wanted to, it's called The Two Captains. I'll also be using aspects from a SuperLock story of mine. Again, it's not completely necessary to read before this, but if you'd like, it's called You're The Devil In Disguise. Hope you enjoy this story :)
Tonight went as any other night at Torchwood HQ. Captain Jack Harkness just got rid of a pretty fugly alien, Gwen Cooper went back home to her husband, Ianto Jones was upstairs working on some paperwork, and now Jack was at his desk in his darkly lit office with a lamp light supporting the light across his face as he read Hollow Earth. He paused and looked up from his book when he heard a noise in his office. He quickly set his book down on the desk and pulled a sonic blaster from his holster. He pulled it out and pointed it at the two shadows highlighted in front of his desk in the already dark room. "Who's there? How'd you get in here?!" Asked a defensive yet commanding Jack.
"Let's just say this place isn't the most discrete or highly secured organization on the planet. A Cyberman could be in this place and you'd never know it. Now I suggest you put that little pistol away. I can guarantee what I've got is way bigger than that little thing." Said a strong, gruff voice that Jack immediately recognized as belonging to Nick Fury, Commander of SHIELD.
Jack smirked and put away his pistol back in his holster. "Long time no see, Nicky."
Fury groaned. "Jack, how many times do I have to tell you, it's Commander Fury. Damn sure don't call me no 'Nicky'."
"Oh but I like Nicky!" Jack said with a coy smile and a gleeful tone. "Fury sounds so...bland and average, like you're trying too hard to intimidate somebody with a name. A commander should have something more demanding, yet opening. Feared, yet trustworthy. Nicky sounds about right, don't you agree?" Jack winked.
Fury rolled his eyes...er...I mean eye, and placed his hands on his hips. "Jack, if you're done being a pain in my ass, we've got business to discuss." He ordered.
Jack couldn't help but chuckle. Him, leader of a supposedly "low tier organization" as Fury called it, always managed to get on the nerves of the commander of SHIELD, the highest tier organization the planet ever had. Kinda boosted Jack's ego a few notches. "No need to use the mom voice, Commander."
"JACK!" Fury raised his voice, clearly losing his patience.
"Alright, alright. Chill." Jack sighed, defensively putting his hands up, though he still couldn't shake the grin from his face. "Let's talk business. What's the problem?"
"What makes you think there's a problem?" Asked Fury.
Jack raised his eyebrows, wondering why Fury would ask such an obvious question. "Gee, I don't know. First time we spoke you told me Steve was in a tailspin. Last time I saw you, you needed my team to save your team's ass. I know you didn't come to be my own personal kiss-o-gram, so why the Hell are you here?"
Fury sighed slightly, deciding it was time to just cut to the chase. "I'm putting together a special team."
Jack scoffed. "Isn't that what The Avengers are for?"
Fury shook his head. "I mean a bigger team. Something big is coming and The Avengers aren't gonna be enough to stop it."
Jack raised an eyebrow curiously. Fury now had his undivided attention. "How big? End of the world big?"
"Bigger." Fury said bluntly without hesitation. "Bigger than the whole damn galaxy, milky way included. I'm talking the end of ALL worlds. I'm talking the end of the universe."
Jack squinted his eyes in confusion. "What's big enough to overthrow the entire universe, and who the Hell is that with you? I see someone in that shadows overthrow." Jack pointed at the dark area behind Fury where light only highlighted a shine from the person's uniform badge. "When I talk business, I like to see the people I'm making deals with so do you mind coming out of the shadows for me? Thanks." He stated, squinting his eyes, trying to get a good look of the person. He wondered who it could have been. He wondered Clint or Natasha or even Maria, but he still couldn't quite make it out.
Fury chuckled briefly, shaking his head. "Jack, no one's hiding. It's just so damn dark in here, you'd suggest otherwise. You don't need to be a detective...we're already looking for a guy who fits that bill...but if you insist..." Fury walked over to the far corner of a wall. "...you should probably flip the light switch on." The lights plopped on, revealing the formerly shadowed figure. Upon sight, Jack's eyes lit up and his mouth dropped with a clear gasp when he saw the familiar blonde. Fury walked back beside her. "To SHIELD, we refer to her by her codename, Bad Wolf, but to my knowledge you know her as-"
"ROSE?!" Jack gasped as he stood up, face engulfed in pure shock. "Wha...how...when...I thought you were in the parallel...but does-" He was beyond speechless for obvious reasons.
"Hello Jack." Rose said simply and calmly without even cracking a smile. "As much as I'd enjoy catching up with you like the quote on quote 'good ol' days', we haven't got the time. We need you to call Martha Jones at UNIT."
Jack could barely get his words out now. He tried his best to keep his mind on the more important matters at hand, but it was hard and damn near perplexing just looking at Rose in her SHIELD uniform. "Uh..." He gulped, swallowing hard. "...why don't you call her yourself? You know she's at UNIT."
"SHIELD and UNIT don't have the best relationship." Fury admitted. "To be frank, they're a bunch of gun toting idiots who would rather make extra-terrestrial contact by poking it with a stick. Since we share different beliefs, they won't answer our calls. We're pretty sure Ms. Jones will always answer yours."
Jack nodded in understanding. "What do you want with Martha?"
"Martha Jones is the only person on the planet who has a direct line to the key ingredient to the team that will help us salvage the fate of the universe..." Rose started to state.
"...The Doctor."
