Three Stood Together! In this issue, the Black Panther changes his name to the "Black Leopard." This was an editorial decision by Marvel, for a time to distance the character from the political organization, the Black Panthers. This would not last long, with T'Challa quickly resuming his traditional Black Panther title in the pages of the Avengers.
After breaking up a dispute between Ben and Johnny, the FF are contacted by aid in T'Challa's Wakandan tribe calls to tell that two men, Nathan Kumalu and Jeth Robards, stole a device called the Vibrotron and disappeared into the jungle with T'Challa following behind. The chase led into the neighboring country of Rudyarda known for its white supremacy government.
Reed sends Ben and Johnny to Rudyarda to free T'Challa and return the device. Along the way, they stop an airplane hijacker. Arriving in Rudyara, they find that Nathan Kumalu was betrayed and left to rot in the slums where the country's ethnic minorities live. Springing T'Challa out of prison, the three (T'Challa calling himself the Black Leopard) locate Robards and find that he's employed by Klaw, who seeks to gain control of the Vibrotron.
The three heroes manage to stop Klaw and Robards and turn them over to the Rudyara police force. When asked to go back to the "colored" part of town because it's after dark, Thing breaks the wall that segregates the two races in the city before the three heroes leave the country.
