Fantastic Four #56
"Klaw, the Murderous Master of Sound!" is written by Stan Lee and drawn by Jack Kirby and Joe Sinnott. Klaw, the menace who swore he'd have vengeance on the Black Panther for thwarting his plans to exploit Wakanda's rich resources, has returned. And now, thanks to his exposure to a machine harnessing the wondrous power of Vibranium, he's in control of sound itself. Able to create any object he can conceive of, Klaw moves to gain his revenge on T'Challa, and means to draw the Jungle Avenger out by striking at the Fantastic Four.
His attack comes as Reed Richards begins to peer into the strange Negative Zone as a means of perhaps freeing the Inhumans who are trapped behind an impenetrable barrier created by the madman Maximus. Klaw's attack is merciless striking first at the Invisible Woman and then at the Thing and Mr. Fantastic. But he didn't count on the timely interference of his greatest foe, the Black Panther who comes through with the solution the FF need in the nick of time. Meanwhile, Johnny Storm, a.k.a. the Human Torch, and Wyatt Wingfoot travel through dimensions with Lockjaw, Crystal's faithful hound, trying to find a way inside Maximus' barrier. This is Marvel magic at its best!
