"I'm just a guy looking for a needle in the world's biggest heystack."
"How do you find it?"
"Pretty simple. You bring a magnet."
Loki smiled at this remark.

They were standing in a highly advanced server room. Tony was working a small tablet in the center, and Loki was standing about five feet away from him. They had come to try to find Ultron in the world's biggest junk drawer. The internet.

"Oh, I'm decryptin' codes and you don't want me to."
Loki softly giggled and covered his mouth with his hand.

Tony typed in a few more, whatever he was typing and said, "come and get me."

"Four, Three
Give em' hell."
Natasha dropped out of the Quinjet on a motorcycle. She landed on a road and started driving as fast as she could to the large blue tractor trailer in the distance.
Cap's sheild was laying on the road before her.
"I'm always picking up after you, boys."
She leaned over and picked up the sheild as she was driving. She planted it on the top of her motorcycle.

"Which way?"
"Hard right..... Now."

Natasha took a sharp turn down an allyway and found herself right next to the truck. She sped under it.
Steve and Ultron were battling on the top of the large truck. Natasha threw Steve his sheild, and he immediately hit Ultron with it.

Ultron, with the blue mist he had earlier, pulled a mound of dirt out of the road, blocking Natasha's path. She stopped and turned to follow the truck, driving up steps and being shot at by Ultron's minions.
"Clint, do you think you can hold them off?"
"I can try."

The Quinjet hovered over the tractor trailer and shot at Ultron on top of it. His two minions flew  up to it as Clint tried to fly it away from the truck. The robots planted themselves on the Quinjet and began sooting at it.
Clint spun it in circles, trying to knock the robots off it.

Cap knocked Ultron into a pillar and Utron flew back at him. The two robots that were harassing the Quinjet flew back towards Utron.
"Heading back towards you. Whatever you're gonna do, do it now."

Cap crashed into a bus along with ultron. They stated wailing at each other, cap trying desperately to get in a good hit.

"I'm going in. Cap, can you keep em' occupied?"

"What do you think I've been doing?"

Natasha propelled herself into the tractor trailer, leaving her motorcycle behind.

The two minions (remember, from earlier?) Planted themselves on the sides of the truck.

There was a metal cradel holding a body inside the truck. Natasha messed with the control panel on the thing, but couldn't shut it off.

The robots on the side of the truck flew the truck upwards. The carrier was flying through the air.

"Okay, the package is airborne. I have a clean shot."
"Negative, I am in the truck."
"Wha-"
"Just be ready, I'll send the package to you."
"How do you want me to take it?"
"Mm, you might wish you hadn't asked that."

Meanwhile, Steve got hit in the side by Utron. He almost fell out of the bus, but Quicksilver (I'm finally using his name) knoked Ultron away from Steve. Scarlet witch bent the bag carrier to block Utron from Steve.

Ultron staired at her. "Please, don't do this."
"What choice do we have?"
Ultron held his hand out to shoot some lazers at Scarlet, but Quicksilver moved his hand as he shot, saving his twin sister.
