Battle of Sokovia

The Battle of Sokovia was a major battle between the Avengers and Ultron in Novi Grad, Sokovia. Convinced that humanity was the greatest threat to peace on Earth, Ultron planned to commit global genocide by creating a device that would lift the city of Novi Grad skyward and cause it to recreate a meteoric impact when it crashed into the Earth. The Avengers' actions, however, resulted in the threat being neutralized and the Ultron Offensive being brought to an end.

The Battle of Sokovia was a very polarizing and controversial incident worldwide; it resulted in a total of 177 fatalities, and a fiscal impact of $474 billion in collateral damage. In 2016, the United Nations ratified a bill of documents enforcing regulation of superpowered individuals under the Sokovia Accords; public opinion was divisive, with most of the blame shifted towards the Avengers. Restrictions were imposed on all artificial intelligence worldwide following the failed integration of the global Ultron peacekeeping program.

First Evacuation
The first evacuation began with Quicksilver and Wanda Maximoff escorting the civilians out of the city. Quicksilver was more aggressive due to them not cooperating at first, then Maximoff used her hypnosis on the people and controlled them to leave their homes. Later, Bruce Banner, along with Thor, were searching for Black Widow, who was held captive by Ultron. Bruce Banner found her first and destroyed the lock with a laser gun, freeing her. Later, Iron Man flew over to the church where Ultron was in his new armor. Ultron then confronted his creator and pointed out that he was stalling to protect the people of Sokovia. Stark replied that that was the mission that Ultron was supposed to complete; however, Ultron countered by saying that he had moved beyond his mission and that he was free.

Suddenly, the Doomsday Trigger jutted out from the ground as Ultron revealed that he too had been stalling until it reached the surface. Just then, the Ultron Sentries also emerged from the ground and the water and began to attack the civilians. This prompted Iron Man and the rest of the Avengers to retaliate by attacking the Sentries. Maximoff attempted to aid her people by moving them off a bridge while Hawkeye bought her time by destroying the drones with his arrows. One of the drones landed and fired at the people, only for Wanda to create a shield and repel the blasts. However, the shield dissipated from the force of the blasts, knocking Maximoff to the ground.

Back at the church, Vision confronted Ultron as the two gazed at one another while taking flight. The Vision pleaded with Ultron that he could change all of this since he was the one who set the terms. Ultron responded by choking the Vision; however, this gave the android the opportunity to hack into Ultron's mainframe and prevent him from escaping through the net. Captain America was battling the sentries on the bridge while Thor fought the robots underground as he made his way towards the machine. Quicksilver soon joined the fray, using his super-speed to take out many drones in the blink of an eye. Vision succeeded in burning Ultron out of the net, but this incapacitated Vision and only stunned Ultron briefly. He smashed Vision to the ground before activating the machine.

Elevation of Novi Grad
Thor reached the boosters of the Doomsday Trigger, only to find himself too late as it was activated. A massive portion of Sokovia began to lift off the ground, as the Avengers could do nothing but watch. The evacuated people watched in horror as their town was lifted towards the sky while those who remained were either crushed by falling debris or falling below.

After Iron Man rescued a family from a collapsing apartment, Captain America ordered the Avengers to destroy the Ultron Sentries and if they got harmed, to harm the opponents in return, and if they got killed, then they should "walk it off." Meanwhile, Wanda Maximoff and Hawkeye rescued civilians while they fought off the Ultron drones. As Hawkeye grabbed Maximoff and took cover inside a house from an oncoming Ultron drone, Wanda began to panic as she felt great guilt in joining Ultron and allowing this to happen. Hawkeye stated that now was not the time to be afraid, and despite being a human with a bow and arrow, he did this because it was his job. Hawkeye could not do a job and babysit at the same time, and it no longer mattered what she did and what she was. What matters was that she fights to protect, and when she does she becomes an Avenger. Hawkeye then went out and continued to fight off the Sentries.

Back in the city at the bridge, two cars were about to fall from the shattered edge. Captain America attempted to save one but the fender dislodged and the two cars fell below. Thor intercepted one of the cars and tossed the woman that was in it back to Captain America as he lifted the second car back up to the bridge. Black Widow joined the battle, using her electric batons to fight off the drones. Captain America and Thor worked in tandem, as Thor batted Captain America's Shield with enough force to ricochet it off of several drones. Thor destroyed many of the drones effortlessly, which irritated Ultron and took him away from his allies. Hawkeye continued to destroy as many drones as he could, but more piled on regardless. However, Maximoff soon joined the fray and used her hex bolts to destroy the Ultron Sentries while using her telekinesis to dismember them. After destroying them, she was carried off by Quicksilver.

Ultron tossed Thor back at the church and began to pummel him savagely. Iron Man was trying to find solutions as to how to stop Ultron's plan and realized that he should redirect the energy back at the thrusters to overload, but F.R.I.D.A.Y. stated that would take the city and everyone else on it. The Avengers, thinking that they were going down along with the city, were then shocked and surprised to see that Nick Fury, along with Maria Hill and several other former S.H.I.E.L.D. agents, had arrived with a Helicarrier provided by Phil Coulson to rescue the stranded civilians. The Ultron drones were about to attack the Helicarrier, only for Nick Fury to deploy War Machine in his new armor, who began to destroy the attacking drones with Iron Man joining the fray alongside his comrade.
