What are simba's grandparnet's names?

Answer 1

Mohatu is the first lion king that Disney gave us. His daughter was Uru, who married a rogue, Ahadi. When Mohatu died, his kingdom was given to Ahadi, who became king as Uru was queen. Ahadi and Uru had two sons: Mufasa and Taka/Scar.

A lion named Everu had two daughters: Sarabi and Sarafina. Sarabi married King Mufasa, and had Simba.

It is thought Sarafina had mated with either Mufasa, Scar or a rogue lion and had Nala.

Scar married Zira and had Nuka.

Mufasa and Scar died, and Simba married Nala and had Kopa.

Kopa dies, Zira marries another lion and has Vitanni and Kovu.

Simba and Nala have Kiara.

Nuka and Zira dies, Kovu and Kiara eventually get married.

Answer 2

Ahadi and Uru, Ahadi being his grandfather.
