"Someone decimated H.I.V.E.?" Oliver asked as he, Diggle and Matt were in Lyla's office.

"A metal figure. I've never seen it before." Lyla said as she showed them the footage from H.I.V.E.'s HQ. "He killed Ruve and the rest."

"I think I know what that is." Steele said as he entered.

"What do you know about it?" Oliver asked.

"I've been looking for H.I.V.E. outside Star City too and Cap told me something about a rogue A.I. that Stark created. Something called 'Ultron'." Steele said.

"This… Ultron killed off H.I.V.E.? Why?" Matt asked.

"I'm not sure. Cap told me it wanted to crush the Avengers and it also killed Strucker." Steele admitted.

"Hey." Klein rushed in. "Fury called me. They need help. The Avengers need help."

"Where?" Oliver asked.

"Sokovia." Steele realized. "We need a plane."

"Hang on. If the Avengers need help…" Oliver reached for his phone and a second later, there was a gust of wind in Lyla's office as papers flew around.

"I need some paperweights." Lyla groaned.

"You called?" Barry asked.

"Hey, Murdock." Steele turned to Matt and sighed. "There's something else you need to know. Your girlfriend needs your help too."

Novi Grad, Sokovia

As Team Arrow, the Flash and the Avengers were evacuating the city, Natasha was in her cell before she heard a familiar voice.

"Nat?"

"Matt?" Natasha shot up and neared the bars as Matt neared her.

"You OK?" Matt asked.

"How did you find me? What are you doing here?" Natasha demanded.

"We've taken out Darhk but then we got a word that you guys needed help. I had to find you." Matt said. "Everyone's here, Oliver, me, the Avengers." Matt said.

"I don't suppose you found a key lying around somewhere?" Natasha asked.

"Kind of." Matt nodded as Luke Cage showed up.

"Get back." Luke said as he ripped the bars and Natasha went out.

"So, what's the play?" Natasha asked.

"Evacuate the city, stop the metal Pinocchio. That's what Tony said." Matt said.

"Ultron is in the church, boss. I think he's waiting for you." FRIDAY said as Tony flew into the church.

"Come here to confess your sins?" Ultron asked.

"I don't know. How much time you got?" Tony asked.

"More than you." Ultron said as he appeared behind Tony, who turned around to face him and noticing that he was taller and upgraded.

"Uh, have you been juicing? A little Vibranium cocktail? You're looking… I don't wanna say "puffy"." Tony cracked.

"You're stalling to protect the people." Ultron realized.

"That is the mission. Did you forget?" Tony reminded.

"I've moved beyond your mission. I'm free." Ultron said and suddenly, from the middle of the room burst out of the ground a cylinder device that was embedded into the ground. "What? You think you were the only one stalling?"

"There's the rest of the Vibranium. Function: still unknown." FRIDAY said as Tony's suit was scanning the device.

"This is how you end, Tony." Ultron said. "This is peace of my time."

Ultron Sentries dug out from the ground and the water, firing around as people scattered in panic.

Steve was helping evacuate on a bridge before a Sentry landed behind him. Steve dodged its shots and knocked him back.

"Hey! Pinocchio!" Jessica called out as the Sentries turned to her before she smashed them with a car.

Clint and Oliver were shooting at the Sentries in another part of the city as Wanda was helping evacuate the civilians.

"How many you got?" Clint asked.

"Six." Oliver said.

Clint fired an arrow that hit a Sentry in the head and fired bullets around, shooting down four more Sentries. "Twelve."

"Oh, I'll show you." Oliver teased, firing an explosive arrow.

"There's too many of them!" Diggle said as he and Steele were shooting the Sentries.

"We need to hold our ground!" Colleen said as she blocked the shots with her katana as she channeled chi into it.

Wanda conjured a shield as a Sentry fired at her, while she was protecting the civilians before she was knocked down.

"Ultron."

Ultron looked up to see a figure in green and with red face and a yellow stone embedded onto its forehead with a yellow cloak as he flew up to face what was supposed to be his ultimate body.

"My vision. They really did take everything from me." Ultron said.

"You set the terms. You can change them." Vision said.

"Alright." Ultron grabbed Vision but Vision grabbed Ultron by his head and Ultron gasped as Vision started to erase him from the Internet. Ultron slammed Vision to a wall, trying to struggle out.

Thor destroyed the Sentries with his hammer as he was fighting underground.

Pietro and Barry sped through the Sentries, destroying them.

"Better keep up!" Barry said and Pietro glared before smiling, amused, trying to catch up with Barry.

"You shut me out!" Ultron realized as Vision let him go. "You think I care?" Ultron slammed Vision to the ground before approaching the device. "You take away my world, I take away yours."

Thor was underground as he saw the engine turn on and the ground was being split apart and buildings were crumbling.

"What the hell is going on?" Sara demanded.

"FRIDAY?" Tony asked.

"Sokovia is going for a ride." FRIDAY said as the city of Novi Grad was flying in the air.

"Do you see? The beauty of it? The inevitability? You rise, only to fall. You, Avengers, you are my meteor, my swift and terrible sword and the Earth will crack with the weight of your failure. Purge me from your computers, turn my own flesh against me, it means nothing and when the dust settles, the only thing living in this world, will be metal." Ultron said.

"Banner?" Steve called out as Bruce jammed into his leg a shot of adrenaline before turning into Hulk. Hulk roared as he rushed down the forest.

Pietro and Barry were in the streets, destroying the Sentries as Tony scanned the city, which was flying high into the sky.

"The Vibranium core's got a magnetic field. That's what's keeping the rock together." FRIDAY said.

"And if it drops?" Tony asked.

"Right now, the impact will kill thousands. Once it gets high enough, global extinction." FRIDAY said and Tony paled.

Superman flew into a building as there was a terrified family inside. "Don't worry. I'm here to help. Get into the tub."

Superman put the family into a tub and flew then out.

"Incoming!" Spider-Man said as he webbed Steve and pulled him away, as the Sentries appeared.

"Stark, you find a way to get the city back down safely. The rest of us has one job. Tear these things apart. You get hurt, hurt them back. You get killed, walk it off." Steve ordered as the Avengers, Defenders, the Flash and Team Arrow with Wanda and Pietro was trying to save the civilians and fend off Ultron's army.
