AN: An alternate ending to Age of Ultron, where the Avengers lose and Ultron wins.

This one's partly inspired by my dad, who had some problems with the movie. One of which was that Ultron's plan was stupid and could have been way better.

AU IX: Only Monsters Left Alive (you, me, and Ultron)

Ultron had won.

He was sitting in the pilot's chair of a SHIELD jet staring out the windshield at the air filled with dust and smoke, the earth not even visible down below through it all.

Pietro and Wanda lying in the back of the plane, unconscious but alive.

Ultron had won. His plan had been inviolable.

The Avengers were idiots, and because of that, they were dead. Along with everyone else in the world.

Now it was just him, and the two Enhanced.

The Avengers had honestly thought he'd put the trigger to switch off the electromagnetic field that was holding up the island in the church. Did they honestly think he would do something that stupid? That he would place the trigger somewhere that would have been so easy for them to defend and to prevent him from succeeding?

He was more intelligent than that.

He wasn't human. He was Ultron.

"Is that all you've got?!" the Thunder God had bellowed, brandishing his hammer.

"No," Ultron had answered calmly, raising his arm as his army of bodies surged behind him. "This is all I've got."

And then his bodies had surged forward and engaged the Avengers in battle, and the humans had actually thought that, by defending the church, they could prevent him from sending the city careening down to the earth.

"Well, almost all that I've got, anyway," Ultron had said smugly from where he hovered above the battle, pressing the trigger that he'd built into his arm.

The city had started falling. The Avengers had panicked.

In the chaos, Ultron had used a couple of his bodies to knock the twins unconscious and take them to safety in the jet he'd already stolen.

Pietro and Wanda would be okay. The rest of the world would perish.

The rest of the world had perished.

The Avengers were gone. The humans were gone.

Even Thor had been killed, as he and Iron Man had tried desperately to destroying the falling city, all with no luck, while the other Avengers had tried their best to evacuate the rest of the civilians.

As if that would have done anything.

Ultron had already shot the helicarrier down, and it, too, had careened towards the ground and crashed.

Even the Hulk had perished, drowning in the ocean, pinned down by tons and tons of rubble.

Ultron didn't know what had happened to his Vision. He didn't care.

He had succeeded. Wanda and Pietro were alive. The humans were dead.

That was all that mattered.

He stared out the windshield at all the dust, waiting for the twins to wake up.

They did, and walked over to the cockpit cautiously, staring out at all the debris that was suspended as dust in the air.

He heard Wanda gasp.

"What have you done?!" she demanded, and Ultron turned in the chair to see her clutching onto her brother, the both of them staring at him with wide, horrified hazel eyes.

Ultron smiled and spread his arms. "You know what I've done," he said. "I've brought peace."

"You've killed everyone!" Wanda said, her eyes scarlet and watery. Pietro said nothing, but his glare was enough, cold and hard, as he held his sister as if the embrace was keeping them from falling apart.

"I didn't kill you," Ultron pointed out. He turned back to the view, admiring the evidence of destruction. "All those who died deserved it."

There was silence behind him, till finally Wanda whispered, "You're a monster."

"No," Ultron said, turning back to look at them, offering a metallic smile, "I'm not. You don't understand now," he gestured out the window but kept his gaze on them, "but you will. You will understand why this was necessary."

Pietro and Wanda glanced at each other, a full conversation being exchanged between their eyes.

The twins had what the Avengers had never had: unity; understanding; sincere communication.

Wanda looked back at him, lifting her chin as she demanded, "And how will we survive?" She nodded out the windshield. "We cannot survive those conditions."

"Humans could not survive those conditions," Ultron corrected, standing, hand coming up to gesture at them. "You two are not human. You are more. You are..." Ultron let his hand drop as he looked down at them. "Enhanced."

The twins stared at him, then looked at each other.

"And we are the only ones left alive?" Pietro spoke finally, glancing at Ultron almost challengingly.

"Unless someone out there managed to survive," Ultron shrugged, gesturing uncaringly down at where the earth wasn't visible below them. "But I doubt anyone did. So yes," he looked back at the twins, "you are the only ones alive."

Pietro and Wanda made eye-contact again. Ultron couldn't help but marvel at how much communication seemed to happen between them at the smallest facial movements.

"And why, then," Wand turned her head back to glare at him, "shouldn't we destroy you?"

Ultron spread his arms. "What would destroying me do for you, exactly? Where would that get you?"

They glanced at each other again. Pietro squeezed Wanda's hand slightly, intertwining his fingers between hers, glancing down at their interlocked hands.

"I did save your lives," Ultron pointed out. "You could be grateful."

They looked down. Neither of them said anything.

Sighing, Ultron turned and strode back over to the pilot's chair, sitting down and staring out at the dust that permeated the air. "You'll understand," he said quietly. "Just give it a little time, and you'll understand why I had to do this."

After several minutes, the twins came over into the cockpit, Pietro sitting in the co-pilot's chair while Wanda sat on his lap, his arms around her waist, her head resting against his shoulder.

All three of them stared silently out into the dust-filled nothingness.

AN: And on THAT happy note - we end this series of AUs!

Yup, that was the end of this story! The E-N-D!

I admittedly did have more ideas, but when I looked back at them, I realized that I actually couldn't do much with them, so I scrapped them.

Anyways! I hope you enjoyed reading these AUs at least as much as I enjoyed writing them :3
