Every MCU Movie Ranked By Death Count
7. Avengers: Age Of Ultron - 235
When the Avengers came together for the second time in the MCU, they came up against a maniacal robot created by Tony Stark, who threatened the lives of everyone on Earth by lifting Sokovia out of the sky and dropping it down like a meteor. Naturally, there were many, many casualties.
The majority of these came in Sokovia itself. Before taking on Ultron, Captain America told his team to clear the field and keep the fighting between just them, but in spite of this, there were 177 civilian casualties, including Zemo's family and Charlie Spencer, all of which would posthumously have a huge affect on Civil War.
There were also 44 HYDRA agents who lost their lives when the Earth's Mightiest Heroes infiltrated Strucker's base, most of which were taken by Iron Man and the Avengers' two master assassins. Barton then went on to kill five of Ulysses Klaue's men in Africa, and Ultron himself killed Strucker, three of Helen Cho's colleagues, the train conductor and three civilians in Seoul, all before gunning down Pietro Maximoff.
Things could have been much worse, but the Hulk's rampage in Johannesburg didn't appear to result in any civilian casualties. There were no obvious lives taken on screen at least, and the incident wasn't brought up by Secretary Ross at the start of Civil War.
