"Tell me something. What do you know about Wakanda?"
"It's a third world country. Textiles, shepherds, cool outfits."
"All a front. Explorers have searched for it. Called it El Dorado. They looked for it in South America, but it was in Africa the whole time. I'm the only who's seen it... and made it out alive."
―Ulysses Klaue and Everett Ross[src]

Ulysses Klaue is a black-market arms dealer as well as smuggler and gangster who had operated out of South Africa. He is a former acquaintance of Tony Stark from his weapons-dealing days. During an encounter with Ultron, Klaue sold his stockpile of Vibranium to the A.I. before losing his arm in an argument with Ultron.


Arms Dealer

Mining Vibranium

"Don't tell me your man swindled you; I sent you six short range heat-seekers and got a boat full of rusty parts. Now you will make it right or the next missile I send you will come very much faster... Now Minister, where were we?"
―Ulysses Klaue[src]

While in Wakanda, Ulysses Klaue enslaved Wakandans to do the mining work, which resulted on N'Jadaka's family being exiled from the country[1] and earned him a branded scar with the symbol for 'Thief' as a form of punishment for stealing Vibranium.[2] Klaue claimed that he was the only man from the outside world who had seen Wakanda with his own eyes and came out of it alive.[3] Working as an arms dealer in South Africa, Klaue had met Tony Stark and Baron Wolfgang von Strucker. Klaue was later paid ten million dollars to assassinate Wakandan King T'Chaka. This put Klaue on S.H.I.E.L.D.'s radar as a new potential threat to world security.[2]

Encounter with Ultron

Threatened by the Maximoffs


Klaue defends himself from the Maximoffs

"So if you're going to fiddle with my brain and make me see a giant cuttlefish, then I know you don't do business and I know you're not in charge, and I only deal with the man in charge."
―Ulysses Klaue to Pietro and Wanda Maximoff[src]

In 2015, while inside his ship in the Salvage Yard, Klaue was on the phone with one of his buyers, threatening him for selling him poor quality missiles before hanging up and continuing another conversation with a minister about their deal. Before he could conclude his deal, the lights in the facility were cut out; Klaue took a handgun and readied himself for a firefight. Before he could react, Pietro Maximoff ran into the room and disarmed him of his bullets.


Klaue mocks both of the Maximoff twins

Klaue found himself face to face with Pietro and Wanda Maximoff. Klaue remained confident, mocking the pair for their youth. Klaue explained he was aware of who the pair were, noting that he was saddened to hear of the death of Wolfgang von Strucker, teasing the pair when he noticed that they were not aware of Strucker's murder. Klaue continued to mock and belittle the pair before stating he only deals with the man-in-charge of their organisation.


Klaue is violently confronted by Ultron

The man-in-charge turned out to be the Artificial Intelligence robot named Ultron, who threw Klaue from his office window and told him that there was no man in charge and that he needed his Vibranium for his new body. Seeing himself to be vastly outmatched by the two enhanced soldiers and the robotic warrior, Klaue relented to Ultron's demands and, with his mercenary by his side, opening his safe containing the Vibranium he had stolen from Wakanda.[2]

Dealing with Ultron


Klaue makes a deal for Vibranium with Ultron

"Upon this rock I will build my church. Vibranium."
"You know, it came at great personal cost. It’s worth billions."
"Now, so are you. It’s all under your dummy holdings?"
Ultron and Ulysses Klaue[src]

Klaue handed Ultron the Vibranium he required, but reminded him of its incredible worth and the personal cost he had been through to get it, having been branded by T'Chaka's soldiers. Ultron responded by filling Klaue's bank account with billions of dollars, which he hacked from financial databases on the internet. Their alliance was cut short when Klaue noted that Ultron was quoting Tony Stark, questioning if he was another one of Stark's robotic designs.


Ultron cuts off Klaue's arm in anger

This comment caused Ultron to go into a rage as he deemed it an insult to be compared to the Iron Legion. Without warning, Ultron sliced off Klaue's left arm, only for the limb to be cauterized from bleeding due to Ultron's heated metal hand; Ultron then apologized immediately while Klaue and his Mercenary could only stare in horror at the assault, unable to comprehend what happened. Ultron's rage continued however as he kicked Klaue down the stairs.[2]

Battle at the Salvage Yard


Klaue orders his men to kill the Avengers

"Shoot them!"
"Which ones?"
"All of them!"
―Ulysses Klaue and Klaue's Mercenary[src]

Knowing he stood no chance in a battle with Ultron, Klaue made his escape. When the Avengers then arrived to confront Ultron and the Maximoff twins, Klaue escaped the scene, clutching the remainder of his amputated arm. Klaue ordered his own soldiers to kill both the Avengers, Ultron and the Maximoff twins, leading to a battle in which Ultron had escaped with the Vibranium and Klaue's soldiers were quickly defeated by the combined efforts of the Avengers.[2]


"I only deal with the man in charge."
―Ulysses Klaue[src]

Ulysses Klaue often acts manic in nature due to his thick accent and tendency to trail off in his thoughts, such as his curiosity with cuttlefish while talking to the Maximoff twins. Conversely, Klaue has shown to be a ruthless arms dealer in negotiation and also a difficult person to intimidate. Therefore, he has since made it his motto to only deal with the "man in charge" which can be witnessed by his lack of fear in Quicksilver and Scarlet Witch despite their enhanced abilities due to realizing they were taking orders from someone else. However, Klaue showed some fear when surprise attacked by Ultron.

Powers and Abilities


After losing his arm due to Ultron and replacing it with a prosthetic, Klaue acquired a number of powers.

"I'm the only one who has seen it and made it out alive."
―Ulysses Klaue to Everett Ross[src]
