FANTASTIC FOUR #53 (2ND APP OF BLACK PANTHER, ORIGIN OF BLACK PANTHER AND KLAW, 1ST APP OF KLAW)
Welcomed as guests of the Black Panther in Wakanda, the Black Panther explains that the nation of Wakanda is unique in that it is home of a rare metal known as Vibranium. Explaining that when explorer Ulysses Klaw came to Wakanda to steal the Vibranium to make weapons, he killed the Black Panther's father. In retribution, the young T'Challa stole one of these weapons and used it to destroy Klaw's camp and in the ensuing battle Klaw's right hand was rendered useless when T'Challa's weapon caused Klaw's pistol to explode in his hand.
When Klaw unleashes solid sound creatures created by a device, the Fantastic Four and Wyatt Wingfoot help Black Panther defend his nation. Tracking Klaw to his hide out, the Black Panther battles him and in the battle Klaw's base is destroyed and his solid sound creations vanish. Surviving and his solid sound device intact, Klaw crawls into the device hoping to gain the power necessary to crush the Black Panther once and for all.
