Chapter 1: The Cyber-Daleks Arrive
The Master was now a conqueror. Missy had raised an army of Cybermen back on Earth in 2015. Once she conquered Earth, she set out with Cyber battleships across the galaxy to the planet Xandar, where she hoped to add this planet to her new empire. Unfortunately, the Doctor, S.H.I.E.L.D. and the Avengers destroyed all the Cybermen she left on Earth in her absence. Missy decided to finish her conquest of Xandar before returning to Earth. Her Cyberships had been hovering over this planet for a year now. The Xandarians put up an intense fight, but Missy could tell that her Cybermen would soon emerge victorious. Missy remained on the deck of her primary battleship in space, watching the battle below. With her was Grant Ward, her new companion. Missy knew that the battle would destroy much of the planet. So, she came up with a plan at the end of 2015 to literally teleport New York City onto this planet, instead of having to build a new capital city from scratch. It would've worked if not for the interference of Clara Oswald, Daredevil, and the Avengers. She also made a deal with Thanos, who was searching for the infinity stones. Missy was to find them for him in return for him allowing her to continue her conquests of the universe. Missy had a new plan to rebuild the broken planet below once she conquered it, which involved a terrible price to pay for planet Earth.
"What are we going to do once we finally win the battle?" Ward asked Missy as he stood next to her on the battleship in space, watching the battle rage on Xandar below.
"The plan is the same." Missy said. "If anything it's expanded."
"I thought we weren't doing that." Ward said. "We tried to teleport New York City here, but that didn't work."
"That's why I'm bringing different cities this time." Missy said.
"You want to teleport more cities here?" Ward asked.
"That way we kill three birds with one stone." Missy said. "Xandar gets rebuilt, Earth gets damaged, and then we'll be able to get one of the stones for Thanos."
"Which one?" Ward asked.
"The Mind Stone is on Earth." Missy said. "It's lodged inside the head of Vision."
"That Avenger?" Ward asked. "The one with the red face and green suit?"
"Where do you think he got his powers from?" Missy asked.
"What about S.H.I.E.L.D. and the Doctor?" Ward asked.
"They'll have too much on their plate." Missy said. "Trust me. I've thought this through. Everything is going according to plan."
Los Angeles, United States 1947
It had certainly been an interesting year so far. Agent Peggy Carter moved out to the west coast in 1946 with her friend Mr. Jarvis. Earlier in 1947, she returned to New York City to visit her friends Amy Pond and Rory Williams. There, she met Agent Coulson, Thor, and some others from the future. She helped them and the Doctor stop a future attack by the Zygons. Now, back in Los Angeles, she and Mr. Jarvis were enjoying a nice late night walk on the beach. The moon and the stars were shining bright, illuminating the dark sky. However, something else was glowing in the sky. It was something unusual. A small bright green object was falling to Earth from space.
"Mr. Jarvis." Agent Carter said. "What do suppose that is?"
"Something not of this world." Jarvis replied.
They watched as the small glowing green object fell in the distance in front of them at the very other end of the beach.
"We've got to see what that is before anyone else can get to it." Agent Carter said.
So, the two of them ran down the beach to see what strange green object had fallen to Earth from space.
Avengers Facility, United States 2016
It had been a crazy year for Earth's heroes. In the summer of 2015, Ultron literally tried to destroy the planet. Just days later, the Master (now called Missy) released an army of Cybermen and conquered the planet. She then left Earth with many of her Cybermen to conquer other worlds. With her gone, the Doctor, S.H.I.E.L.D., and the Avengers were able to destroy the Cybermen on Earth by sucking them through the Cardiff Rift. However, something came out of the Rift as well. It was Rose Tyler, the Doctor's former companion. She traveled back to this universe to seek help in defeating the Cyber-Daleks, a hybrid race of Cybermen and Daleks that originated on her parallel universe. The Cyber-Daleks had conquered the entire parallel Earth, which had its own version of the Doctor. However, this human Doctor went missing in the outbreak of the Cyber-Dalek attack and was presumed dead. Rose thought her only chance of saving her world was to find the Time Lord Doctor again. Clara Oswald decided to stop traveling with the Doctor for now so she could focus on her relationship with her boyfriend Danny Pink. So, The Doctor and Rose spent the last few months traveling the universe together again, looking for something she could use to return home and defeat the Cyber-Daleks.
Agent Coulson and S.H.I.E.L.D. were having a busy year as well. After defeating Jiaying, the Zygons, and the Cybermen, they had to focus on an Inhuman crisis. Jiaying had released special chemicals into the world that exposed and created Inhumans, people with super human powers and abilities. S.H.I.E.L.D. raced against H.Y.D.R.A. to find them. On top of it all, Jemma Simmons was missing for six months. She was trapped on the planet Maveth after falling through a portal known as the monolith. They eventually rescued her, but H.Y.D.R.A's evil ambition brought something evil back from that world as well. But that was a problem for another day. Also in 2015, Missy attempted to literally teleport New York City off planet Earth and move it across the galaxy. The Avengers teamed up with Clara Oswald, Danny Pink, some more of the Doctor's companions, and New York's vigilante hero Daredevil to defeat her. Unfortunately, not everyone made it out of this mission alive. The very same day that Clara and Danny set a date for their wedding, Danny Pink was killed in action. Clara was devastated.
Iron Man and Hawkeye took a step back from the Avengers. Thor was on Asgard and the Hulk was still missing. Now, in 2016 at the Avengers facility, Captain America, Black Widow, War Machine, Falcon, Scarlet Witch, and Vision watched as a Cyber-Dalek teleported into the blue sky. This was impossible. These evil killers should not have been able to figure out how to travel across parallel universes. If what Rose Tyler told them last year was true, then they needed to destroy this thing immediately. It looked exactly like a Dalek. However, it was purely silver and was ten times more powerful. On the parallel world, it was created by Tony Stark to defend the Earth when the Avengers couldn't. It was manufactured to be indestructible and powerful. The six Avengers were outside, scattered on the ground. They assumed the Cyber-Dalek would begin attacking. Instead it started talking.
"Where is Tony Stark?" The Cyber-Dalek asked with the voice of a Cyberman.
The question threw the heroes below off guard. An evil alien robot was hovering above them, waiting to strike. Why was it asking about Tony Stark? No one wanted to wait and find out. Captain America threw his shield with intense force at the Cyber-Dalek. However, it merely bounced off the creature and knocked it back slightly. He then caught the shield, surprised that it did not shatter the creature. Falcon and War Machine then flew up across from it and unleashed rounds of bullets at it. However, as with both Cybermen and Daleks, the bullets were ineffective and simply bounced off the creature. The Cyber-Dalek then fired a blue laser blast at the two flying heroes. Scarlet Witch used her powers to surround War Machine and Falcon in a red force field. The heroes were shielded from the blast, but the laser was so powerful that it broke the shield instantly. Vision then flew up in between the heroes and the Cyber-Dalek. He had the Mind Stone, one of the six infinity stones, lodged in his head. If that couldn't destroy the Dalek, then nothing could. A yellow energy blast shot out of its head, hit the Cyber-Dalek, and destroyed it. Soon after the battle, the Avengers regrouped with Agent Maria Hill in the conference room.
"How did that thing get to this universe?" Captain America asked.
"Travel between parallel worlds is supposed to be impossible, but there are always ways around it." Vision said. "Apparently the Cyber-Daleks have found one."
"That means they could be sending more." Maria Hill said.
"We need to warn Tony." Black Widow said. "They clearly want him for something."
"And S.H.I.E.L.D." Maria said. "Coulson needs to be aware of this. They've been doing work with Inhumans and travel between planets. Maybe they have something that can help."
"What about the Doctor?" Falcon asked. "Shouldn't we be trying to contact him."
"We can't." Captain America said. "We have no way to reach him."
"Clara does." Scarlet Witch said.
"She's all the way in London." War Machine said.
"Then it looks like some of you are going to London." Agent Hill said. "Here's what's going to happen. There are six of you. You'll split up into three teams of two. One team will go to Malibu and get Tony. One team will go to S.H.I.E.L.D.'s secret headquarters and get a team from Coulson. The last team will go to London and get Clara Oswald and hopefully the Doctor. I'll watch the base while you're all gone. I suggest you all leave as soon as possible."
It was now night in the United States. A full moon loomed over the dark world below. Three quinjets had left earlier that day. Captain America and War Machine took one out to California to talk to Tony Stark. Black Widow and Vision took one to S.H.I.E.L.D.'s secret headquarters to talk to Director Coulson. Falcon and Scarlet Witch flew one across the Atlantic Ocean to England in order to talk to Clara Oswald. In the darkness of the night over the Avengers Facility, two blue flashes of light briefly shined in the sky. Two more Cyber-Daleks had just teleported to this universe. Unfortunately for them, that was it. The Cyber-Daleks lacked the power to send any more of them from the parallel universe. It was up to these two to find Tony Stark if they ever wanted to complete their evil mission.
