The Battle at the Salvage Yard was a confrontation between Ultron, the Avengers, and Ulysses Klaue's men at an African salvage yard. It erupted in the closing stages of a transaction between Ultron and Klaue, as Ultron purchased the Vibranium that Klaue had stolen from Wakanda years earlier.
Ultron had finished building a new body at the HYDRA Research Base and recruited Quicksilver and Scarlet Witch to his cause. They then proceeded to obtain information on Klaue from Wolfgang von Strucker before murdering him. Ultron went to the Salvage Yard with the twins in order to obtain Vibranium from Ulysses Klaue. The Avengers would soon follow suit. Thor and Captain America attempted to peacefully confront the trio, but Ultron attacked Iron Man.
Iron Man and Ultron started fighting while flying through the Salvage Yard. Thor and Captain America started fighting some Ultron Sentries. Quicksilver also joined the battle fighting the Avengers. Ulysses Klaue's forces started shooting at the Avengers and Ultron's forces. After Captain America defeated the Ultron Sentry he was fighting, he went to fight Quicksilver but Quicksilver knocked him out temporarily.
Scarlet Witch started going around the Salvage Yard looking for the Avengers. She soon found Black Widow, Captain America and Thor. She gave them all visions leaving them powerless. When she went to give Hawkeye a vision he turned around shocking her with a electric arrow until Quicksilver came and knocked him out. Iron Man was able to defeat Ultron's current form and went back to help his friends until he had to go to Johannesburg with the Iron Man Armor: Mark XLIV to stop the Hulk.
