New York City was a battlefield for the second time in five years. The Chitauri had launched another invasion, only with triple the army size as the first attempt. What was more, they were once more being led by Loki and being assisted by a strange group of aliens called 'Slitheen', a large group of plastic shop-window dummies and a strange middle-aged woman in purple Victorian clothing. All the Avengers were in New York City, old and new, fighting these invaders, with Maria Hill and Coulson's SHIELD team assisting in the evacuation and protection of civilians.

"Okay, so bullets can injure these 'Slitheen' things, but how do we actually kill them, Thor?" yelled Black Widow, a.k.a. Natalia Romanova, through her comm. "I have little idea, Natalia," said Thor as he crushed another Chitauri's skull with his hammer, Mjolnir. "Well, we need to know now!" said Hawkeye as he fired another arrow at the Chitauri soldiers trying to attack him. Thankfully, Stark had convinced the government not to get involved, as more deaths would occur if they did.

"Well, you were right," said Loki, turning to the woman, "using more soldiers, Autons and the Slitheen was a good idea." The woman turned to the God and said in a sardonic voice, "Yes, but it's a double-edged sword. We'll tire out the kiddies in capes and Spandex, but this is so big an invasion that HE is bound to show up at some point." Loki raised an eyebrow in confusion before setting his mind back to the battle on the streets below. All the news outlets in the world were broadcasting the fight live, so just about everybody on the planet was viewing the battle as it was happening right now.

Which meant that everybody in the world heard a strange wheezing sound echo through the main street of the Battle, before a blue police box began to materialise in the heart of the warzone.


The Chitauri, Slitheen, Autons, Avengers and the woman turned their gaze to the blue box, before a grey-haired man walked out, dressed in an indigo jacket with crimson lining, a blue waistcoat with black buttons, black brogues, dark blue trousers and a black dress shirt that was fully buttoned. His blue eyes widened and stared at the chaos that was happening.

"So, there really are people that can protect this planet?" he muttered to himself, before speaking loudly in a Scottish accent, "Why are you here? This planet has been invaded countless times in the past, and each invasion has been stopped with painful casualties for the would-be invaders.

"The human race is just starting to get up and stand by itself. Given another few hundred thousand years, there won't be a single part of the universe where this species, this wonderful, violent, curious species, has not touched. Why do you insist on trying to prevent it from happening?"

Loki scoffed before coming down to the man. "You are the fool. This planet was promised to me; it is rightfully mine! So you would be smart if you-" He was interrupted by the man punching him in the face, knocking him to the ground. Thor ran towards the man and yelled, "Midgardian, I understand my brother has done wrong, but he is my brother. I wouldn't be pleased if you did that again."

The man turned to Thor, then to Captain America, and took out a metal device from his pocket and the nearest TV camera before taking out an object that resembled a stethoscope. A whirring noise could be heard as he placed the parts of the stethoscope-thing to his forehead, above his eyes. Then, the man attached the third end of the device to the camera, and tinkered with the camera to ensure that everybody in the world, and on all the planets that were preparing for invasions or wars involving Earth.

In effect, a universal transmission.


Images began appearing. First was an elderly gentleman in early Edwardian dress commanding two younger people, a man and a woman, to help fight a group of metal men, and then of the same man fighting another man dressed as a monk, and finally the man hugging a much younger woman, who the Avengers concluded was either his daughter or granddaughter. The man was also seen walking into a blue police box, which revealed itself to be much bigger on the inside than the outside.

Then another man appeared, younger than the first and with a black bowl-cut, dressed in a black blazer with bowtie, fixing a machine, before he was shown running at a group of reptilian creatures with a device that looked similar to the metal device the man in New York right now had.

The third group of images showed that same man in a court, being sentenced to exile on Earth, and inside a control room (impressing Tony Stark, aka Iron Man), with a bright light coming from him, which soon covered his face and hands, with his height and build changing. After a few minutes, the light vanished, revealing the man to have changed his appearance to a tall individual with grey hair and a pronounced nose. He was then shown dressed in a velvet smoking-jacket and Inverness cape, activating another metal device, which set off a minefield and destroying several creatures, attacking something that looked like a giant salt shaker with plunger and egg whisk arms and eyestalk called a Dalek, and duelling with another man who had a goatee and a prison uniform.

The fourth set featured a younger man, with a dark coat and an extremely long scarf, facing off against a man whose body was rotting, a giant robot with the aid of a young woman, who Steve, Natasha and Stark recognised as Sarah Jane Smith, an intrepid and dedicated journalist, and then appeared another woman, in a white dress, arguing with the man about a strange cube that appeared to have been made out of a puzzle. There were also images of the same planet the courtroom was on, with the man being elected as President, as well as images of 1930s Hong Kong, and the man and woman with the white dress facing off against some Triad gangsters.

The fifth series showed a man much younger than the first four, dressed in a cricket outfit with a piece of celery on his lapel. He was shown discussing scientific matter with a young woman dressed in purple, and arguing with another woman in a black dress and white shirt. There were also scenes of some metal men with handle-like appendages on their heads.

Then came a man with curly hair and a rainbow-coloured coat, which appalled the young woman he was travelling with. He was shown arguing on the planet he was first tried on (now revealed to be named Gallifrey), about a trial that had been rigged, shouting "Ten million years of absolute power, that's what it takes to be really corrupt!" He was also facing off against another man with a goatee and black clothes, and a middle-aged woman with a short jacket on and several pieces of technology.

The seventh image set showed a dark-haired man around the same age as the last one, dressed in his clothes. He was then shown fighting the Daleks, only dressed in a light blazer, full brogues, Panama hat, question-mark pullover and a paisley scarf and tie, and assisted in defeating them by a young adult dressed in black with a backpack and a baseball bat. He was then shown to be fighting the same metal men, and the second man in a goatee, who had gained cheetah-like facial characteristics.

Then came a younger man in a Victorian frock-coat and cravat, with wavy brown hair, fighting a man dressed the same way as the people on Gallifrey, and kissing an American doctor. He was then seen against the Daleks again, a group of diminutive soldiers with a potato-like head and blue armour, and exiting a console room that appeared to be the same one that had been shown several times already, only this time it was a light brown, and he was wearing shorter hair and gaiters.

The next group featured horrific acts of violence and war, with the Daleks killing people left and right, and the people of Gallifrey committing equally acts to the salt-shaker creatures, with another man shown fighting both, dressed in a leather jacket which became increasingly worn, gaiters, a scarf and a bandolier. Over the ages he was shown to be getting older and older, a beard forming on his face, which showed sadness, weariness and regret, most likely at the atrocities he was involving himself in.

Then there showed a younger man, with a buzz cut and leather jacket, holding hands with a young blonde girl as they ran from the same plastic dummies as the ones fighting in New York, before going to the end of the Earth, World War II and the year 500,000, where they fought an army of Daleks.

A younger, thinner man, with spiky hair and a pinstriped suit that varied, showed up next, kissing a waitress that looked like Kylie Minogue whilst in a tuxedo, marrying Queen Elizabeth I of England, stopping Prime Minister Harold Saxon, meeting William Shakespeare and Agatha Christie, and saving school-students with Sarah Jane Smith and the blonde girl, before fighting the creator of the Daleks and pointing a gun at the President of his people.

Next up, a young man with a large chin and a tweed blazer with bowtie appeared, tricking some new Daleks, kissing a Victorian governess under the mistletoe, battling the metal men, marrying the woman who would apparently kill him, and being chased by vampires.

The final set of images featured this man, staying in a small town, fighting nearly every alien race he had fought before over a period of nine hundred years until the Daleks were all that were left. He then appeared to inhale some energy that came from a crack in reality, before a bright light appeared, causing massive amounts of energy to erupt from him, destroying the Dalek fleet and sending shockwaves throughout the surrounding area. He was then shown in the console room, talking to a young woman who looked too much like the Victorian governess, before removing his bowtie and changing into the man who was currently in New York.


The Avengers watched these images come from the man's head, and Barton realised that all the men shown were the exact same person, and that this was an alien unlike any of the other ones. "Look, the X-ray shows a binary vascular system, he's changing his appearance to avoid death and that technology is not from here!" he explained. Stark landed and saw the man turn to all the aliens, and knew it would be better to stay put.

"I think that little slideshow of all my memories proves to you all who I am, eh?" he yelled. Loki turned and noticed the woman had vanished, having flew off to fight another day.

"I am the Oncoming Storm, the most dangerous man in the Universe. There isn't a single galaxy I haven't set foot in. I am 4,000 years old; I am a Time Lord from the planet Gallifrey in the constellation of Kasterborous. There are armies with as many soldiers as there are humans on this planet right now, armed with nuclear weapons and impenetrable armour, who'd turn tail and run for the hills the moment I say my name. Shoot me now-I'll just regenerate. Try and convert me into a Cyberman- My physiology isn't compatible with them. Attempt to get secrets out of me in prison- The interrogators would end up helping me escape. I am the one man-no, wait, the one BEING you do not let know about an invasion. If you'd killed people, I'd be angry. If you'd killed a LOT of people, I'd be really angry. And forget a woman scorned-Hell hath no fury like me when I'm pissed. Because I. AM. THE . DOCTOR."

He said the last two words louder than the rest of his speech, and Stark thought he was a bit crazy if he thought that a speech and his name would scare off this invasion, but the moment the man said the words "The Doctor," every single one of the Chitauri, Autons and Slitheen ran off, and began retreating from New York and Earth.

"Jesus," breathed out Bruce Banner and Sam Wilson, both surprised at the speed and haste the invaders had left Earth at, and Wanda Maximoff, the 'Scarlet Witch' was rubbing her head, as if she had the worst migraine in history. "What is wrong, Wanda?" asked the android Vision. "I accidentally read his mind," said Wanda. "And?" asked Steve, walking over. "He's seen and done things nobody should have to see or do. That war he showed from his memories, Steve, was like how you described World War II. Only mixed with WW1 and made infinitely more horrendous."


Six hours later, the Avengers and SHIELD team had all gathered at the New Avengers Facility when they heard the wheezing sound of the blue box. They saw the Doctor step out, only dressed in grey-and-black wingtips, a white shirt with the first button undone, his trousers now had vertical stripes, his waistcoat was a lighter shade of blue, and his jacket was a dark purple with scarlet lining, with only the first button done.

"How long did it take you to get here?" asked Stark sarcastically, to which the Doctor replied, "It's been six hours for you, but me, well, I just spent the weekend with my granddaughter, stopped the Daleks from invading the planet Ribos in the space of a day, and spent a week in Barcelona. Not the city, the planet."

Coulson raised his eyebrows. "You mean there's a planet called Barcelona?" to which the Doctor nodded, adding, "It's quite nice, actually."

"So let me get this straight, Doctor," said Bruce Banner, pointing at the box, "that thing can travel to anywhere in the universe, anywhere in space?" The Doctor smiled and answered, "Yes. It can also travel through time and is dimensionally transcendental." Stark, Wilson and Banner looked at each other and grinned. Steve was the first to answer to the 'time-travel' point: "If you can travel through time, can't you prevent Bucky from falling off the train, or Stark's parents from dying, or even Hitler from starting WW2?" The Doctor sighed, looked down at his feet and replied, only in a much more somber voice, "I can't. They're fixed points in time, which means that those events have to occur, or else paradox upon paradox will start happening, and possibly trigger the end of reality."

Steve's expression saddened, though his eyes gained a bit more positivity when he asked, "Could I go see Peggy's wedding?" The Doctor then smirked, saying, "There's nothing that says you can't be there, Steve. I should be able to call you that, after all, you do remember those bullies in 1928, right?"

Steve's eyes widened, and his eyebrow went up, before he asked again, "You were the old guy in the frills and the cape, weren't you?" The Doctor's smirk became a full grin, and he nodded, before beckoning the super-soldier into the box, along with Wanda, Coulson and Barton.

"Why us?" asked Wanda, to which the Doctor replied, "Well, we'll be taking turns. For everybody outside, it'll more than likely be ten minutes. For us, a day or two. Maybe a week." Barton laughed softly, as he and the other two walked in, unaware of the shock they would receive when they were all inside.

"Wait, wait, wait! How will the four of you fit in there?" asked Natasha. The Doctor grinned a mischievous grin, saying, "Why not wait and see?" before he stepped inside and closed the door.


Capaldi's Doctor, because he needs more crossover fics.
