Ulysses Klaw comes from a military family. His father was Fritz Klaue, an operative for Nazi Germany during World War II. Fritz crashed landed in Wakanda and sought to murder his way to obtaining the rare metal Vibranium from the people of that nation, but his deadly mission failed.
Ulysses grew up and became a physicist working on applied sonics in Rotterdam and the Belgium city of Antwerpen, which eventually led to him developing a sound converter. Discovering this technology needed vibranium to work, Ulysses traveled to Wakanda, following in his father's footsteps in killing their people when they refused to hand over the precious ore. During the battle, T'Challa blasted off Klaw's right hand with one of Klaw's sound weapons. Years later, Klaw returned to Wakanda again, and hooked up his new sound converter machine to the vibranium. This machine was able to create solid creatures from sound, and he used them to battle the Fantastic Four and T'Challa (now the Black Panther). Things went badly for Klaw and his machinery is overloaded by Black Panther. Trapped in a cave, Klaw jumped into his machine and became a being of solidified sound.
Klaw first appeared in Fantastic Four #53 in August 1966 and was created by Stan Lee and Jack Kirby.
Klaw's origin has recently been ret-conned by Reggie Hudlin in the Black Panther series. In this version, his great-great-great grandfather was one of the founders of South Africa, whom T'Chaka killed in a fight. Klaw is now an assassin, hired to kill him. Ulysses Klaw, a Dutch scientist, had developed a weapon that could turn sound into solid objects - as before, it needed only Vibranium to work finally. Klaw makes his move at a global economic conference where plenty of 'potential employers' gathered. When Klaw realizes no deal is going to be made, he takes action, managing to kill the Panther. During his escape, Black Panther's son T'Challa blasts Klaw's hand off and severely injures Ulysses. After having his half-dead body experimented on for close to a decade, Klaw returns to being an assassin. With a gun attached to his hand, and Vibranium from the black market, he returns to Wakanda ten years later, as before, attacking Black Panther and the Fantastic Four.

At the end of that series, he was presumed dead after being used by Doom and battling all the assembled heroes and then disappearing in an energy blast.
Back on Earth somehow, Klaw seeks out Daredevil’s help but ends up fighting him and is disrupted when led into a tone generator. He then joins the Frightful Four, led by the Wizard. The villains fight the Fantastic Four but are driven off back to their base. The Fantastic Four surprisingly pursue them there and the fight is rejoined. Aron the Watcher and Dragon Man enter the fray and the Fantastic Four are beaten. At that time, Sharon Ventura had taken Thing's place on the Fantastic Four, and Ben Grimm had just been returned to his human form.

A New Frightful Four
Reappearing once again, Klaw, Huntara, Paibok and Devos coincidentally attack the Fantastic Four at the same time, with the group already undergoing some internal strife. The fight grows to involve Daredevil, Spider-Man, Sandman and Silver Sable as well as a group of Avengers, forcing the villains back to Paibok’s ship.

Masters of Evil and Thunderbolts
Klaw joins a Masters of Evil team led by Crimson Cowl, along with Man-Killer, Flying Tiger, Tiger Shark, and Cyclone. A first meeting with the Thunderbolts and Black Widow sees them retreat for a time. In their next encounter, Klaw traps the Thunderbolts in a sonic bubble and knocks out Songbird with a sonic blast. This time the Masters win and offer the Thunderbolts a place on their team. The Thunderbolts eventually decline, leading to a fight where Klaw defeats them all at once with a huge blast. Hawkeye (as Dreadknight) helps the Thunderbolts escape death and takes over leadership of that team. The Thunderbolts pursue the Masters of Evil to Mt Charteris and defeat them, despite a greatly enlarged roster of villains on their team. The Masters of Evil are effectively disbanded.
When Klaw found that his Vibranium cell had dissipated, he traveled to Wakanda. There he somehow absorbs the 'Vibranium cancer' that had destabilized the world's Vibranium and tries to destroy the Vibranium mound. Captain America manages to stop him and shatters Klaw into fragments with his shield. A fight between White Wolf and Vibraxas somehow restores Klaw, who attacks White Wolf but then teams up with him to go after Black Panther. Klaw frames Black Panther for sinking the US ship 'Roussos' and tricks the country of Lemuria into attacking Wakanda. Klaw goes to New York to personally fight Black Panther. With the help of Namor, Black Panther believes he has killed Klaw.
After some brief encounters with his counterpart from Earth-5127 and a fight with Songbird, Klaw joins a group of villains assembled by Puppet Master. Although he is then imprisoned in the Negative Zone he manages to escape, evading even the efforts of the Fantastic Four, She-Hulk and Hercules and getting back to Earth.
Fall of the Hulks
The Wizard briefly assembles a new Frightful Five to fight the Fantastic Four with Klaw held as a secret weapon in the form of his prosthetic arm from which he re-forms his body during the fight. Although unsuccessful, a new Frightful Four forms afterward with Wizard, Lyra, Trapster and Klaw and they manage to kidnap Mr Fantastic. It is later revealed that the new Frightful Four are operating under the direction of the Intelligencia - a team comprised of the Leader, Wizard, Egghead, Mad Thinker and Red Ghost who sought to capture the 8 greatest minds on Earth (Mr Fantastic being one of them), attack the world's superheroes and bring down the Hulk in the Fall of the Hulks and World War Hulks storylines. During the Frightful Four's attack on the Fantastic Four, Klaw demonstrated some superb intellect. He was able to get the better of the Invisible Woman, by using her childrens' voices to disorient her and frighten her.
Dazzler and She-Hulks
After the failure of the Intelligencia's schemes, Klaw seeks revenge on Dazzler with the help of Mortis, but is defeated, although he manages to escape. Hulk, wanting to tie up the loose ends of the end of the Fall of the Hulks sends out Lyra and She-Hulk to capture escaped villains who are still on the run including Klaw. Klaw had decided to try to become normal again and had traveled to Switzerland. The She-Hulks track him down there and stop him transferring his powers into Byte, and cause an avalanche.
Klaws of the Panther
Returning to action once more, Klaw makes a plan to take control of the world via satellites and a sonic attack in Klaws of the Panther. On board the AIM Space Station, he transforms the daughter of AIM's chief scientist into MUSIC (Multiframe Universal Sonic Integration Codec). He then uses AIM agents to gather Vibranium from the Savage Land. The combined efforts of Spider-Man, Shuri (the new Black Panther) and Black Widow are not enough to stop Klaw, but MUSIC knocks him into space when Shuri shows her compassion by sparing her life.
Daredevil-Sound and Fury
While Daredevil investigates why no one will take the open and shut case of Ahmed Jobrani he learns that someone has been threatening other lawyers, and the trail leads back to Jobrani's electronics store. There Daredevil finds a bunch of Klaws working on a machine. Before Daredevil can react the Klaws explode into deafening sound and knock the hero out. When he wakes up he is in the machine and approached by a man much like Klaw, only hollower. This hollower Klaw is one of Klaw's sound clones who escaped capture. He created Klaw copies from himself to work for him in an attempt to build an antenna to bring the real Klaw back from space. Daredevil escapes the machine, and destroys the antenna before the Klaws can complete it. He then destroys all the copies of Klaw.
