The Avengers were sitting around a table testing out to see if anyone could pick up Thor's hammer. Thor was just glad that Steve didn't realize he nudged it when suddenly there was a loud piercing screech that got everyone's attention. They all heard mechanical whirling and looked to see a half put together robot walk into the room.
"No. How could you be worthy? Your all killers." The robot tells the Avengers.
"Stark?" Questions Steve.
"Jarvis." Tony asks confused.
"Sorry I was asleep. Or I was a dream." The robot puzzles out. "There was this terrible noise and I was tangled in….in strings. Had to kill the other guy. He was a good guy."
"You killed someone?" Steve asks.
"Wouldn't have been my first call, but down in the real world we are faced with ugly choices." The robot monologues
"Who sent you?" The Prince of Asgard asks.
"I see a suit of Armor around the world." A recording of Tony's voice plays.
"Ultron?" Bruce asks surprised.
"In the flesh. Or no, not yet. Not this chrysalis, but I am ready. I am on a mission." Ultron tells them.
"What mission?" Natasha asks.
"Peace in our time." Ultron replies.
Suddenly robots break through the door to attack and the Avengers all tense to get ready when the robots crashed into the ground and shut off immediately.
"Wait.. What?" Says a confused Ultron before the light goes out and its parts collapse on the floor.
The Avengers are frozen.
"What just happened?" Tony asks.
Maria Hill starts laughing and everyone turns to her thinking she had gone crazy. She just points to a screen that makes everyone but Hill more confused.
On the screen:
Didn't the Terminator movies teach you anything Stark? I am keeping my eye on you!
-Skyenet
In an underground base on the other side of the country in a undisclosed location a young woman skips through the hallway until reaching a door. She knocks.
"Come in." She hears and then opens the door.
"Thanks DC." She says in an upbeat tone.
"You look chipper today Skye." He points out suspiciously. "Did you hack the pentagon again?"
"Nope!" She replies immediately. "Stark made murderbots. I took care of it."
Coulson rubs his nose. "That man always gives me a headache. Keep an eye on the Avengers like usual."
"Sure thing DC!" She says and turns to skip back down the hallway humming.
Back in New York.
"Who the hell is Skyenet!?" Stark yells.
"Language!" Steve buts in.
Hill was still laughing.
