He was hired to take down T'Chaka at the Blinderberg conference in the case that he refused to negotiate Wakanda's resources, including Vibranium. He has a history with T'Chaka, as the Panther killed Klaue's great grandfather in the 19th Century while this one was trying to anex Wakanda. He was paid ten millions dollars for the kill, which was unsuccessful.
Years later, Klaue went to Wakanda, where he stole large amounts of Vibranium. However, he was discovered by the Wakandian population, who decide to tattoo the word "thief" on his neck.
