Ulysses Klaue

A physicist-turned-arms dealer, Ulysses Klaue murdered the Wakandan chief T'Chaka to steal a cache of vibranium, earning the undying enmity of T'Challa. An accident transformed him into a being of living sound energy, leaving him with a sonic disruptor replacing his right hand.

Born from the legendary imaginations of Stan Lee and Jack Kirby in Fantastic Four #53 back in 1966, Ulysses Klaue is a genuine Silver Age Marvel villain whose shadow has stretched across nearly six decades of comics. With 111 catalog appearances and five key issues to his name, he's far more than a footnote — he's a recurring menace whose presence is felt across Fantastic Four, Black Panther, and even the landmark Marvel Super-Heroes Secret Wars. The company he keeps tells you everything about his stature: his pages are shared with titans like Captain America, Iron Man, and the Human Torch, placing him squarely in the thick of Marvel's most consequential stories. If you're building out your Marvel reading history, Klaue is one of those enduring antagonists whose debut issue alone is a collector's milestone worth tracking down.
